Chinese emissions peaking now; India's soon

Another telling chart from Carbon Brief

Let's first look at China.  

The height of the bars shows the total increase in the demand for electricity, each year, in TWh (terawatt-hours). One TWh = 1000 GWh (Gigawatt-hours) or 1 million MWh (Megawatt-hours).  

So in 2020, Covid caused low growth in total demand, and this was mostly met by renewables.  But in 2021, demand rebounded strongly as Covid lockdowns were partially removed, with the result that only a third of the increase was met by renewables.   Excluding the jump in demand in 2021, the rise in electricity demand each year over the last 3 years is the highest it's been.   And each of those three years, the percentage supplied by renewables has risen, and in 2025 it exceeded 100%.  

Economic growth will increase electricity demand each year, on average, but the key point is that non-fossil supply growth (30% per annum) is much faster than total demand.  Now that it's reached parity, the gap will widen.  Renewables will more and more rapidly eat into coal's market share. 

If you add the S-curve acceleration of EV sales, it is clear that China's emissions have peaked.  Which means world emissions have peaked too, though don't expect a rapid plunge — yet.


India's story is a bit different.  Yes, renewables filled more than 100% of the increase in demand last year, but that's because demand growth was low (due to an early-onset monsoon reducing temperatures below previous years', meaning less air conditioning was needed).  India's growth in electricity demand is about 85 TWh per annum, but is expected to increase, while the increase in supply from renewables was just 71 TWh.  So if the summer heat is typical this year, supply from coal will increase, meaning emissions will increase.  But the growth rate in renewables is much higher than the growth rate in demand.  These lines will soon cross over again.

Here's what Carbon Brief says:


India added 35GW of solar, 6GW wind and 3.5GW hydropower [capacity] in the first 11 months of 2025, with renewable energy capacity additions picking up 44% year-on-year.

Power generation from non-fossil sources grew 71TWh, led by solar at 33TWh, while total generation increased 21TWh, similarly pushing down power generation from coal and gas.

The increase in clean power is, however, below the average demand growth recorded from 2019 to 2024, at 85TWh per year, as well as below the projection for 2026-30.

This means that clean-energy growth would need to accelerate in order for coal power to see a structural peak and decline in output, rather than a short-term blip.

Meeting the government’s target for 500GW of non-fossil power capacity by 2030, set by India’s prime minister Narendra Modi in 2021, requires just such an acceleration.

CREA (Centre for Research on Energy and Clear Air)  believes that China's emissions from electricity have peaked, and India's will peak in 2028.  I concur.

However, CREA points out:

[...]one major obstacle common across China, India, and Indonesia is the continued addition of new coal-fired power plants and mining capacity. The new clean energy infrastructures being built in each country creates powerful resistance from the coal industry, which will only intensify once coal demand begins to contract. This political and economic inertia threatens to slow the clean energy transition and lock in high-carbon energy systems in these countries for decades to come, making a rapid post-peak decline in emissions far from guaranteed.

The continued fall in the costs of solar panels and batteries will be a powerful countervailing force, because of course, coal is not getting any cheaper, but governments in all three countries would be wise to ban all new coal power stations immediately.  They won't be needed.

Solar doubling every 3 years

 From EV Curve Futurist


We’re about to hit the phase of the S-curve where the world goes from “fast” to “holy shit.” Solar’s doubling on a 24-month cycle — but the real elephant in the room is . As storage scales, the grid stops being a bottleneck and starts becoming a battery-backed solar engine.




Solar is by far the cheapest source of electricity. And the plunge in battery costs means that it can now provide what used to be called baseload power, cheap and carbon-free. It's doubling every 3 years (the chart says 2 years but the text says 3, and Our World in Data also says 3, so I'll go with 3). In 2024 solar provided 7% of the world's electricity, Total electricity demand rose by 2582 TWh over the last 3 years, while solar alone rose by 1077 TWh. With solar doubling every 3 years, solar should rise by ~2100 TWh over the next 3. Wind rose by 640 TWh over 3 years. If demand grows by 10% over the next 3 years, the rise in supply from wind and solar will meet 96% of the rise in total electricity demand. And when solar doubles again, over the subsequent 3 years, demand for electricity from coal power stations will plunge. Emissions from electricity generation will have peaked.

Sodium-ion even cheaper than I thought

I wrote a piece a month ago about CATL's new sodium-ion battery.  The video I link to provided more information, suggesting costs are even lower than I said.

The cost at cell level will be $19/kWh vs lithium-ion phosphate (LFP) of $55-$60/kWh.  CATL expects $10/kWh in a couple of years.  $45/kWh at pack level, less than half the cost of LFP.   Production can be carried out on existing assembly lines, so they don't have to rebuild the entire factory.  Any factory making LFP could pivot to sodium-ion at minimal cost and time.   

They will retain 85% after 3.6 million miles.  I said 80% in my earlier piece; so this is even better, meaning that after 50 years, 75% of the battery capacity will remain.  Their life will be 3-6 times longer than the best LFP packs.  Energy density has dramatically improved.  A year ago it was 120-140 Wh/kg, too heavy for EVs. The new energy density is 175 Wh/kg, better than BYD's current blade battery (160 Wh/kg).  They can be charged and used from -40 Celsius to +70 C.  And they use abundant materials: sodium, aluminium and carbon.  They are maintenance free.  They can be safely transported at zero charge, unlike lithium batteries.  CATL has also developed a pack made up of both sodium-ion and lithium-ion cells, combining the best qualities of both. 

Years ago, the rule of thumb was that if battery pack costs fell to $100/kWh, that would make EVs cost the same up-front as ICEVs (petrol vehicles).   (EVs are already much cheaper to run)  We have shot way past that point.  The introduction of sodium-ion batteries means that ICEVs will no longer be cost-effective, and production will cease.  

But this will also transform the grid.  The cost of storage has more than halved, and will halve again.   Solar is already the cheapest electricity for everywhere except high latitudes, and now it can be combined with enough dirt-cheap storage to provide base-load power.   That probably means 8 hours of storage, but storage will be so cheap that even 12 hours will be perfectly feasible and economic.  High latitudes will still need long-term storage, but when your EV dies, the batteries will still have another 50 years plus of life in them, and then they can be shipped to high latitudes to provide completely free long-term storage.

This spells the end of the fossil fuel economy.   Except for air transport and cement making, everything we now do with coal, oil or gas will be doable with cheap electricity from solar plus sodium-ion storage.

Even in the USA, even with 25% tariffs on imported batteries, the plunge in storage costs means that the EV and storage revolutions will continue.

Have emissions from electricity peaked?

 From EMBER.

Global [electricity] demand rose by 369 TWh (+2.6%) in H1-2025, compared with 731 TWh (+5.3%) in the same period last year. The smaller increase was due to a few factors, including a more measured pace of industrial growth in China and India, but also fewer heatwaves in May and June in India.

In China, demand grew by 198 TWh (+4.2%), compared with a much stronger increase of 326 TWh (+7.5%) in the same period last year.

Despite the smaller rise, the global demand increase in H1-2025 was close to the 10-year annual average of 2.7% for 2015-2024.

In India, demand growth was particularly low at 12 TWh (+1.3%), compared with +75 TWh (+9%) last year when heatwaves drove higher demand. Ember estimates that if weather during May and June 2025 had matched last year’s heatwave conditions, demand growth in India would have been closer to +3%.

The world’s four largest polluters accounted for 81% of the global demand rise in the first half of 2025: China 54% (198 TWh), the US 21% (76 TWh), India 3.3% (12 TWh) and the EU 2.4% (9 TWh).




Solar generation grew by 306 TWh (+31%) in the first half of 2025, its fastest absolute growth on record. If this pace continues, solar is on track to remain the fastest-growing source of electricity for the 21st consecutive year and to outpace wind growth in absolute terms for the fourth year in a row. 

Solar’s global share was 8.8% in the first half of 2025, more than doubling in the last four years, from 3.8% in 2021. In many countries, solar now makes up a considerably higher share of the electricity mix.Several economies set new records. Among the top 20 largest solar generators in absolute terms, seven countries — Hungary, Greece, the Netherlands, Pakistan, Spain, Australia and Germany — generated 20% or more of their electricity from solar in the first six months of 2025.

Hungary led with nearly 30% share of solar generation, ahead of Greece and the Netherlands, which both surpassed 25%, up from just over 10% only four years ago (in the first half of 2021). Meanwhile, based on Ember’s estimate, Pakistan saw the largest increase in share, from 4.4% in H1-2021 to 21.9% in H1-2025. The increase was driven by the rapid adoption of rooftop solar by households and businesses in response to high electricity prices, as reported previously by Ember.

Based on available monthly data, at least 29 countries generated over 10% of their electricity from solar from January to June 2025, up from 22 countries in the same period of 2024 and only 11 countries in the first half of 2021.

China remained the leader in absolute growth terms for the third consecutive year, accounting for 55% (168 TWh) of the global increase in solar in the first half of 2025. The US accounted for 14% (44 TWh), the EU 12% (37 TWh) and India 6% (17  TWh). In contrast, solar generation fell marginally in Japan by 1.4 TWh (-0.4%), partly due to record-high curtailment. Solar also declined slightly in Vietnam (-0.5 TWh, -1.7%).


Solar capacity additions also grew at a record pace, reaching a new high of 380 GW in the first six months of 2025 – 64% more than the 232 GW added in the same period last year. A record surge in May, driven by accelerated installations in China ahead of new pricing rules on 1 June 2025, was a key contributor. Overall, China accounted for 67% of total solar capacity additions in H1-2025.


Renewables overtook coal in the electricity mix for the first time on record, rising by 363 TWh (+7.7%) to 5,072 TWh in the first half of 2025. Their share increased to 34.3%, up from 32.7% in the same period last year. Coal fell by 31 TWh (-0.6%) to 4,896 TWh, with its share dropping to 33.1%, down from 34.2%.




My view on these figures:

The output of solar is rising by 30% per annum, and because solar panels and battery storage keep on falling in cost, that growth rate will continue, and may even accelerate.  This half year, solar output rose 306 TWh over the year, so in H1 2026, it could easily rise by 400 TWh, H1 2027 by 517 TWh, and in H1 2028, by 673 TWh.  Assume there is no acceleration in wind output, i.e., the annual increase in output remains at 100 TWh.   

World growth is likely to pick up.  The switch to EVs is accelerating, and datacentres are gobbling electricity.  Demand growth for electricity will be higher over the next year, and higher still in 2027. But, if world electricity demand rises by, say, 500 TWh in the year to H1 2026 (compared with 369 TWh in H1 2025), this will be satisfied by the increase in renewables supply.  Similarly, in H1 2027, demand could rise by more, say 550 or 600 TWh, and still be met by the increase in output from renewables.  By H1 2028, demand would have to rise by a record 770 TWh for renewables not to match this increase.  And thereafter, renewables will eat more and more deeply each year into generation from fossil fuels.

In other words, emissions from electricity generation have probably peaked.  

Declines will be small initially, but the stronger rise in electricity demand is (partly) to supply electricity for EVs. The decline in emissions from land transport will be accelerating.  

We are at, or are close to, the point where not just emissions from electricity generation, but also total global emissions, are peaking.  This is not a cyclical peak, caused by a recession or Covid.  It is a secular peak.  We have at last started on the long road to zero emissions.  Does that mean temperatures have stopped rising? No, unfortunately.  For that, we would have to cut emissions by at least 90%.  However, we're getting there.   Emissions could halve by 2045, and halve again by 2060. Definitely too long and too slow.  But we are at last on the right road.  Now we must try and bend the curve to get there faster.

Politicians favouring fossil fuels are idiots

 From Professor Ray Wills:

Only excuse for politicians who

  • continue subsidies on costly fossil fuels
  • think nuclear power is cheap
  • claim clean energy is expensive
  • want to end decarbonisation?

Idiots

Only idiots ignore the data

My model projections from 2018, and updated 2025:

Prof Wills wasn't 100% correct in his forecasts back in 2018 (nearly 8 years ago).  On the other hand, he was among the least wrong.  The IEA (International Energy Agency), for example, consistently, year after year, underestimated the growth in renewables, and overestimated the growth in demand for fossil fuels.  I myself thought that emissions from coal peaked in 2018, and instead there was a surge in electricity generation from coal in China.  You can read about my latest forecast that emissions have peaked, here.

2018 forecasts

Wills sees oil peaking in 2027, and coal and gas peaking now.

2025 forecasts

Note that the two charts below show primary energy consumption, which is much more than, say, electricity production, because three-quarters of the fuel burnt to generate electricity or to power an ICEV is wasted as heat.

2018 forecasts

2025 forecasts


You'll notice that Wills doesn't think nuclear will grow:

Most important reason nuclear isn't viable in one graph

Apart from long build, it's expensive electricity, [and] if it's really hot, you need to turn them off


Not to mention that all the lethal by-products. 



Global solar output overtook nuclear output 2025

Global wind output will pass nuclear output early 2028

Now here's where some peeps lose it and call me a loony:

[In] my model projection, renewable[s] will pass fossil fuel primary energy consumption in 2035 

Does that mean that we will have halved emissions by then?  No, because there is still growth in demand.  But each year that the share of renewables rises means that demand growth will be increasingly supplied by renewables.

India's renewable electricity reaches new record

 From Reuters


Clean electricity production in India has surged by 20% to new highs so far this year, giving utilities a rare chance to cut fossil fuel-fired generation and reduce reliance on energy imports for power production.

India's clean electricity sources are also on track to provide a third of its utility electricity for the first time over the next month or so, thanks to record combined output from renewables, hydro and nuclear assets, data from Ember shows.

The steep build in home-grown clean electricity comes just as India faces unprecedented scrutiny over its energy import practices, particularly its heavy reliance on sanctioned Russian oil that has triggered stiff new tariffs from the United States.


Solar output rising exponentially


India also faces pressure to boost imports of U.S. LNG as a means to reduce its trade deficit with the United States, but has steadily reduced its reliance on gas for power as clean energy output has increased.

Continued growth in clean generation - alongside rising homemade production of clean energy tech such as solar panels and battery systems - may help India limit its reliance on foreign-sourced fossil fuels while continuing to expand its overall energy generation.

Over the first half of 2025, India's utilities generated a record 236 terawatt hours (TWh) of clean electricity, data from Ember shows.

That total is 20% more than during the same months in 2024, and allowed utilities to curb generation from fossil fuels by 4% from the year before to around 691 TWh.

A 29% jump in wind generation (to 47.2 TWh) and a 25% rise in solar generation (to 85 TWh) were the main drivers of the advance in clean electricity supplies.

The collective upswing in multiple clean generation sources is leading to clean power grabbing a record share of India's generation mix, which will likely exceed 30% for the months of July, August and September.

 



Over the first half of 2025, total clean generation from all sources was around 24% more than average generation levels from India's clean generation assets during the same months from 2022 to 2024.

If wind and hydro production rise as expected during July, August and September, total clean electricity production in India will smash previous records this year and may set the stage for even steeper cuts to fossil fuel generation going forward.

Given the fast pace of electricity demand growth in India, utilities are likely to continue adding coal-fired generation capacity to the generation system to ensure that overall electricity supplies keep up with consumption.

But with solar and wind capacity expected to continue growing at a faster pace, the share of fossil fuels within India's overall generation mix may be close to peaking, which would mark a major milestone for India's fast-growing energy system.

An established peak in the share of fossil fuels in electricity generation could then trigger a potential decline in fossil fuel imports and use, and reduce the pressure on India to succumb to international pressure on oil and gas import trends.


In this piece, Emissions have peaked, I argued that China's emissions have most probably peaked, because of the extraordinarily rapid roll-out of solar, and the S-curve rise in EVs as a percentage of total car sales.

Europe's emissions peaked in 1990.  They are back at 1965 levels.   The USA's emissions peaked in 2007, and its emissions have fallen to 1987 levels. The UK's emissions peaked in 1973, and are back at 1880 levels.  Japan's emissions peaked in 2013.  

If China's emissions have peaked, then the big remaining emitter where emissions must peak, is India.  And it looks as if India's emissions might be close to peaking, too.  Emissions from fossil fuel electricity generation fell 4% in the first half of this year.   Yet India is booming---the average annual GDP growth rate over the last 5 years was 7%.  In other words, despite high growth, the share of renewables still rose and fossil fuel emissions still fell.  

Global emissions have almost certainly peaked.   And this is at least in part due to the plunge in solar and battery prices, which have moved switching from fossil fuels to renewables from a luxury only rich countries could afford to a necessity where even poor countries are willing to do it.  Global emissions will fall slowly at first, but the decline will accelerate as solar, battery, and EV prices continue to decline.  And when emissions have fallen enough, global temperatures will stop rising.

Emissions have peaked

Two recent graphs, from different articles, have given me hope that we might yet avoid catastrophic global warming.  The first chart come from Carbon Brief, which I referenced here.



Let's dig deeper into the chart.  

It shows the smoothed year-on-year change in electricity demand in China, and the year-on-year change in the supply of electricity, broken down into fossil fuels (mostly coal, but some gas) and clean energy.  Over the last 20 years, there have been 5 times when production of electricity from fossil fuels has fallen: in 2009 (the GFC); in 2012/13 (the Euro crisis); in 2016 (a global mid-cycle correction which was quite severe in China); in 2022 (Covid lock-downs); and this year.

This year is the first time that fossil fuel production has fallen when electricity demand growth is strong.   Notice how the size of the pale blue bars (renewables) has got bigger and bigger, as China has installed exponetially increasing quantities of wind, solar and batteries.  Second, notice how electricity demand has grown, as (a) the economy grew, and (b) EV sales exploded, with each peak tending to be higher than the previous one.

Right now, an annual expansion in clean energy production of +-600 terawatt-hours (TWh) is enough to more than satisfy demand, causing fossil fuel generation to decline.   The 20-year average annual increase in demand is 400 TWh, while over the last 8 years or so, it looks about 500 TWh.  Obviously, if China's growth accelerates back to the heady rates on the early 2000s (10% a year), given how much richer China is now than then, the increase in demand could easily exceed 800 TWh.  However, growth is unlikely to accelerate back to those levels  The recent GDP trend growth rate is about 7%, and, in my judgment, slowing, as China deals with its property crisis.  (Also, China overstates its GDP growth data, so the real growth rate is lower.  The data for growth in electricity demand and supply are better quality.)  

The second chart came from an article by the ABC,  which I  commented on here.




The projected increase in new clean energy generation capacity for the next 2 years is about 600 TWh.  In other words, it's now more than the average rise in electricity demand.  

Of course, there is an economic cycle, with demand rising at 800 TWh in boom years, and reducing to 200 to 400 TWh in slower years.  So we may have a pattern of  falling emissions during low-growth years, followed by modest rises when the economy is stronger.  Yet this doesn't take into account the exponential growth in new wind and solar output over the last 7 years.   It's risen from 200 TWh to 600 TWh in just five years.  And although the forecast for the next two years is for only limited growth, the costs of solar and batteries contimue to decline rapidly.  The exponential growth will continue.  By 2028, new clean energy output will be increasing by 800 TWh a year, or more, so that even in high growth years, Chinese emissions from electricity generation will be falling.  

China is by far the world's largest emitter of CO2, causing over 25% of global emissions, compared with the US at 18%, and the EU at 17%.   Europe's and the USA's emissions peaked years ago:


Source: Our World in Data

What this means is this: if China's emissions have peaked, global emissions have probably peaked too.

It's true that the Trump administration has embarked on an utterly demented attempt to return the USA to the 1950s,  but cheap Chinese solar panels, batteries and EVs, are persuading the rest of the world (for example, Pakistan)---the other 80% of emissions---to switch to clean energy.  Plus, Trump's high-handed trashing of tariff and trade agreements means that the USA's opposition to carbon border taxes will not be effective.  If the USA can arbitrarily raise tariffs, then so can the rest of the world.  And they will.  Moreover, renewables are much cheaper than fossil fuels.  As electricity prices soar in the USA, cooler heads might prevail.

The peak in global emissions doesn't mean global temperatures will stop rising.  Emissions will have to fall by 90% for that to happen.  But what these devlopments do mean is that emissions are now in secular decline.  And the sustained fall in the costs of clean energy means that the decline will accelerate as renewables and EVs get ever cheaper.  As the impacts of catastrophic global heating worsen, the world will take stronger and stronger measures to slash emissions.

Temperatures will go on rising, but for the first time, it looks as if, by the 2040s, the decade-by-decade increases will start falling.

Some progress on emissions is happening

 From The Guardian


There is something of a reality check under way on the response to the climate crisis. It’s no secret that countries and corporations are far from living up to the goals set by international leaders at the landmark 2015 Paris agreement.

Unless there is a significant course correction, the ramifications will be far-reaching and often destructive. The second coming of Donald Trump and growing global instability has made a top-down injection of urgency at the pace needed harder to imagine. Optimism is harder to come by.

But that doesn’t mean nothing is happening.

It’s worth pointing this out because a narrative has started to take hold that renewable energy and other clean solutions have made little to no headway in displacing fossil fuels, and therefore are pointless. Fuelled by Tony Blair and the former US government adviser Daniel Yergin, and embraced by the fossil fuel industry and its lapdogs in the commentariat, it is used to attack zero emissions targets as a fool’s dream. In Australia, it is part of the backdrop as the Albanese government is lobbied over whether to set an ambitious emissions reduction target for 2035.

The reality, though, is more complicated. Here are some things worth considering if you hear climate action is pointless.

Clean energy is coming for fossil fuels

 

One line that has gained some traction this year is that the proportion of global energy supply from fossil fuels has barely moved over the past 35 years. The claim – bubbling away in The Australian, on Sky News [right-wing Murdoch media] and on social media – goes that dirty fuels provided 85% of energy in 1990, and still provide 80% today.

So much for progress, right?

But the Bloomberg New Energy Finance [BNEF]founder and self-declared conservative Michael Liebreich points out that this ignores an important factor.

The percentages referred to by fossil fuel advocates are for primary energy – that is, raw coal, crude oil, gas, wood, sun or wind. They do not refer to useful energy – energy that has been converted into a transportable form, such as electricity or refined petroleum, delivered to a consumer and then used to light their house or move their car.

This useful energy is the more relevant measure. And the process of processing raw fossil fuels into useful energy is, in many cases, not particular efficient. More energy is lost in generating at a remote coal-fired power plant and transmitting it to a home than if solar, wind or hydro was used. Petrol cars require much more energy to travel a kilometre than an electric vehicle does.

If we acknowledge this and consider useful energy alone, Liebreich says the amount of energy provided by fossil fuels is not 80%, but about 68%.

This is obviously still too high. But it won’t stay at this level. Despite all the talk of new coal plants still being built, they are playing in the margins. The International Energy Agency (IEA) forecasts that solar and wind will meet more than 90% of the global increase in electricity demand this year. Global generation from solar and wind energy is expected to increase by about 25%, from 4,000 terawatt-hours to more than 5,000. Next year it is expected to jump another 20%, past 6,000TWh.

The IEA projects that global renewable energy output – including solar, wind and hydro – will surpass coal output in either 2025 or 2026. For the first time in a century, the share of electricity coming from coal will have fallen to less than 33%.

Solar and wind will together be nearly 20% – up from 4% a decade ago.

A key question is if this growth in renewable energy will eventually reduce global fossil fuel use – as is necessary – or mostly just meet growing energy demand. Liebreich argues compellingly that fossil fuel use is set to fall. Using a simple model, he suggests it is likely to start falling in the 2040s and could be squeezed out of the system by about 2065.

That is not near fast enough to deliver the trajectory scientists say is needed to limit global heating since pre-industrialisation to 1.5C. But it is a well argued rejection of claims that a global transition isn’t possible.

China? It’s moving

 

With a population of 1.4 billion and having taken on a huge proportion of the world’s manufacturing, China is easily the world’s biggest direct national climate polluter, pumping out more than twice as much CO2 as the second-placed US.

Its story is mixed, as always. But the data show it is changing. An analysis for Carbon Brief by China experts Qi Qin and Lauri Myllyvirta found that coal’s share of the country’s power generation fell from 73% in 2016 to 51% in June this year. This happened as it continued to build new coal plants for a simple reason – it doesn’t run them at anything like capacity.

A significant moment came earlier this year when China’s national emissions fell for the first time, dropping 1% in the first quarter compared with a year earlier. Beijing needs to do much more if it is to meet its commitment under the Paris deal. Its next five-year plan for economic development, due this year, will be crucial.

Source: Carbon Brief
Note how renewable electricity generation has, for the first time since the deep 2009 recession, grown by more than the growth in electricity demand, even though demand growth has been strong.


Dirty car sales are down

 

According to Our World in Data, global sales of internal combustion engine cars – which run solely on petrol or diesel – peaked in 2016 at 80.47m. Electric and plug-in hybrid car sales in that year were just 780,000.

Last year, sales of dirty cars were 62.05m, a 23% fall. Electric and plug-in hybrid car sales had increased to 17.5m.

Put another way, nearly a decade ago only one in every 100 cars sold across the globe was electric. Now it is more than one in five. Elon Musk’s extraordinary self-own in damaging Tesla’s reputation may dent the pace of growth but it won’t stop it. China has little time or need for Teslas and is home to more than 60% of global EV sales.

Still a mountain to climb

None of this is to understate the scale of the problem. This column has reported before on the big step-up in global heating since June 2023. Averaged across the globe, every day in 2024 was at least 1.25C hotter than preindustrial levels, and three-quarters were 1.5C hotter.

Extreme weather events are becoming more damaging. Feedback loops (melting permafrost and huge wildfires) are releasing large additional amounts of CO2, accelerating the problem. Governments have barely started to acknowledge the expected increase in economic, societal and environmental costs that will hit productivity – the current focus of the Australian political class – and so much else.

It’s hard to overstate how much there is to be done. But don’t believe self-interested arguments that action is impossible, or will be for nothing.

China is becoming the world's first electrostate

In April this year, China installed more solar power than Australia has in all its history. In one month.

This isn’t a story about Australia’s poor track record on solar; Australia is a global leader. Rather, this shows the astonishing rate at which China is embracing renewable technologies across every aspect of its society.

But don’t make the mistake of thinking this transformation is driven by a moral obligation to act on climate change.

China’s reasons for this are less about arresting rising temperatures than its desire to stop relying on imported fossil fuels and to fix the pollution caused by them.

The superpower has put its economic might and willpower behind renewable technologies, and by doing so, is accelerating the end of the fossil fuel era and bringing about the age of the electrostate.

“The whole modern industrial economy is built around fossil fuels. Now the whole world is moving away from that and that means that we are rebuilding our economy around emerging clean tech sectors,” said Muyi Yang, the lead China analyst at energy think tank Ember.

“Once the new direction is set, the momentum will become self-sustaining. It will make reversal impossible. I think China now has set its direction towards a clean energy future.

“Can you imagine that the Chinese government will say that, oh, we will go back to fossil car, not the electric cars? That won’t happen. That’s not possible … this momentum is becoming so strong.”

It’s hard to communicate the scale of China’s clean technology rollout but it helps to look back to recent history to appreciate the transformation.

China became the world’s factory at the end of the 20th century, manufacturing cheap, low-quality products. This industrialisation modernised the country but also caused widespread environmental damage and drastic air pollution.

The factories were powered by fossil fuels, causing China’s emissions to skyrocket and it to become the largest polluter in the world.


China overtook the United States for top place in 2006, but the US is still responsible for the most emissions historically, at one-quarter of all emissions.

 


Still, China’s pivot to renewables wasn’t just about addressing these rising emissions.

With polluted waterways and acrid city smog long ago becoming their own crises, China had to act. Part of that response, starting a decade ago, was a plan called Made in China 2025, which outlined how it would reshape its manufacturing capability to focus on high-tech products, including the ones needed to address climate change.

The authoritarian regime put the heft of the state behind clean technologies at a scale and pace difficult to imagine in most democracies.

It began to invest in all components for renewables, especially wind, solar, electric cars, and batteries that are used for both transport and energy storage. To do this, it used significant government-funded subsidies, said Ember’s Muyi Yang.

“We all understand that young sectors and technologies need some protection for them to grow. It’s like helping a baby to learn how to walk; initially, you need to support them.

“But I think the logic behind China’s policy support is always clear — this support is not meant to be pumped up indefinitely.”

When China rose to industrial dominance in the 1990s, it realised that it could maximise output by developing hubs where all parts of a supply chain for a product are built in the same region. The same approach was applied to renewables, meaning battery factories were established near car plants, as an example.

“It’s not about subsidies. It’s about sound planning, sustained commitment, and targeted support,” Yang said.

As the Made In China plan unfolded, more and more power was needed to fuel these energy-hungry factories and the lifestyles of the burgeoning middle class. To keep up, China built new coal-fired power stations, even as it was installing more wind and solar.

This “dissonance” between China’s booming renewables and coal has meant China is painted both as a climate hero and a villain.

It’s also meant that emissions kept rising.

[However,] a decade after the Made in China plan began, the country’s clean energy transformation is staggering.

“It’s a really interesting policy because it’s a 10-year plan to become a world-leading clean tech manufacturer, which they’ve outright achieved,” said Caroline Wang, the China engagement lead at the think tank Climate Energy Finance. “They’ve made themselves indispensable in the new kind of global economy.”

China is home to half of the world’s solar, half of the world’s wind power and half of the world’s electric cars.

“In the month of April alone, 45.2GW of solar was added, more than Australia’s total cumulative solar power capacity,” Caroline Wang said.

“China’s renewable capacity has exponentially increased and that has also contributed to the drop in coal, in coal use and emissions. There is now a structural kind of decline of coal.”

That’s already having an impact on emissions:



Recent analysis from Carbon Brief found the country’s emissions dropped in the first quarter of 2025 by 1.6 per cent. China produces 30 per cent of the world’s emissions, making this a critical milestone for climate action.

With its unmatched economies of scale, this dramatic acceleration has also brought down the cost of electrification across the world and made China the world leader in clean technologies. Chinese-made electric cars are becoming more dominant on Australian [and Thai, and Malaysian, And Brazilian ....] roads — something that’s already happened for the solar panels and batteries installed across Australian homes.

“China has successfully helped the rest of the world lower the bar for them to embark on the transition. This makes it easier for many other countries to jump on board,” Ember’s Muyi Yang said.

“The transition has to be affordable, otherwise it will be extremely difficult for many developing countries.”

China’s clean energy exports in 2024 alone have already shaved 1 per cent off global emissions outside of China, according to Carbon Brief, and will continue to do so for the next 30 years.


Caroline Wang points out that this green era has also brought major economic benefits.
“It drove 10 per cent of their GDP last year — just the one industry, clean energy. It’s overtaken real estate, and that says a lot because real estate was the driving force of their economy until a few years ago. But now it’s been overtaken by clean energy,” she said.

China’s renewables expansion is also striking because it could not be more different to the direction of another world superpower, the United States, under the leadership of President Donald Trump.
Casting aside the climate damage it will wreak, the US is in a position to return to its “drill, baby, drill” roots because the country produces more than enough fossil fuels to cover its own needs.

That’s not the case for China. One of the key reasons it has pivoted to electrification is to get away from its dependence on imported fossil fuels. 

“I think there’s some deep strategic thinking … it’s not only about the environmental obligation or international commitment, and it can also not be fully explained by economic benefit in terms of jobs and investment,” Yang said.

“Energy is a basic input for economic activities. Energy security is critical because it’s critical for supporting a functioning economy.”

“China sees the old, the conventional fossil fuel growth model as not sustainable. And it is becoming increasingly unable to sustain long-term prosperity.”

When the world’s economies became hooked on fossil fuels, they became dependent on the countries that could supply them, and the price of fossil fuels increasingly dictated global markets.

“This dates back to issues in the 1970s with the [oil] crisis,” said Jorrit Gosens, a fellow at the Centre for Climate and Energy Policy at the Crawford School of Public Policy at the ANU.

“That’s really when people start to think about energy security, especially when we talk about China.

“China typically is described as very rich in coal, but very poor in natural gas and oil.”

Electrification is changing that, and China — the world’s biggest oil importer — is already weaning itself off with electric cars.

“If you go to Beijing today, you can honestly stand at intersections with four lanes going every way and it’ll be quiet as a mouse. The noisiest thing coming past will be a creaky bicycle,” Dr Gosens remarked.

Last year, crude oil imports to China fell for the first time in two decades, with the exception of the recent pandemic. China is now expected to hit peak oil in 2027, according to the International Energy Agency.

This is already having an impact on projections for global oil production, as China had driven two-thirds of the growth in oil demand in the decade to 2023.

The 20th century was dominated by countries rich in fossil fuels, and many of the world’s conflicts fought over access, power and exploitation of them.

Done right, electrification could change that too, as most countries will be producing their own electricity.

“Even if you have pretty poor-quality natural resources, you can still squeeze quite a bit of electricity out of a solar panel. It’s really changing the geopolitics,” the ANU’s Dr Gosens said.

“Renewable energy is the most secure form of energy that there is because you just eliminate the need for imports.

“But also the cost of it, right? It’s a stable cost. You lock it in as soon as you build it. You know what the price of your electricity is going to be. You get insulated from both those risks if you have more renewable energy.”

For Australia, one of the world’s largest exporters of coal and gas, there is plenty to take from this, with China’s furious electrification paving the way for the rest of the world to follow.

“Even if we have these climate wars here still … we can bicker about how quickly we should transition away from fossil fuels domestically [but] the rest of the world is ultimately going to decide how much they’ll be buying of our coal, gas and iron ore,” Dr Gosens said.

“I think that’s the biggest risk — that we fail to prepare for something and that these changes will be much quicker than we currently anticipate.”

For Climate Energy Finance’s Caroline Wang, it’s in Australia’s interest to be clear-eyed about what’s happening in China.

“I think a gap in Australia and other Western countries is knowledge and understanding. China is a complex country … it’s got good and bad. For the energy transition space, which is full of complexity, there’s a real need, for our strategic national interests, for Australia to understand what is happening in China.”

Finding hope in national self-interest and security might seem strange, but for Wang, China’s transformation makes her more optimistic about the climate crisis.

“This is the world’s largest emitter, the largest population. If they’ve managed to do it in quite a short time — a decade — it’s a kind of achievement that we haven’t seen any other country achieve. And so it’s very inspiring. Seeing that on the ground gave me hope for other countries, including Australia … there are lessons there to be learned.”

Renewables boom in China

 From Nicholas Fulghum (who works for EMBER)


In the first five months of 2025, coal power has fallen in China compared to 2024.

Solar power is up 120 TWh, meeting 86% of the increase in electricity demand.

Wind also up substantially

Demand rose by 130 TWh, but solar rose by 120, and wind by 72, leading to a decline of 64 TWh in coal.  

However, growth in electricity demand has been relatively low so far this year, reflecting China's economic doldrums.  If growth picks up, electricity generation from coal will return to positive growth again.  

All the same, last year (2024) generation from renewables grew by 17%, which means it's nearly doubling every four years.  In 2024, renewables (excluding nuclear) provided 34% of total electricity.  Demand trend growth over the last 10 years has been 6% per annum.   This will likely pick up as EVs move to 100% of car sales and of the car fleet.  So demand growth may accelerate, unless economic growth slows.  At, say, 8% demand growth, generation from coal will peak in 2028.  At 6% (because China's trend GDP growth rate may have slowed enough that even extra demand from EVs doesn't lead to an acceleration in electricity demand), the peak occurs next year.  Under either demand growth scenario, all coal generation ends by the mid 2030s.  And remember: the accelerated rise in electricity demand is because electricity is replacing petrol (gasoline) and diesel in the car/lorry fleet. 

We are within sight of China's emissions peaking.  It won't happen this year, but it's possible next year, and probable by 2028.  That's unambiguously good news.

Wind + Solar provide 26% of China's electricity

 From Nicholas Fulghum

Wind and solar generated more than a QUARTER of China's electricity for the first month on record In April 2025, 26% of China's electricity generation was produced by wind and solar according to our latest data. Wind: 13.6% Solar 12.4%


As the EMBER piece says: 


The April record was driven by both wind and solar hitting individual record high shares. Wind power accounted for 13.6% of generation while solar contributed 12.4%. The rise of solar power in particular has been remarkable. The share of solar power has tripled in the last five years, from just 4.1% in April of 2020. In 2024, China installed more new solar capacity than the rest of the world combined, more than tripling its rate of installations in just two years, from around 103 GW (DC) in 2022 to 333 GW in 2024. Installations have continued at pace in 2025, with 72 GW of new solar added in Q1 alone, up 18% from Q1 2024, according to Ember’s monthly wind and solar capacity data.

The rapid build out of solar capacity in China has pushed not only the share, but also absolute solar generation to new heights. In April 2025, China hit a new record of 96 TWh of solar generation, surpassing the previous record of 89 TWh set in August of 2024. This record may soon be surpassed again as summer conditions further boost output. 

The growth in renewables is also reshaping the overall generation mix. Fossil fuel generation has already declined by 72 TWh—or 3.6%—year-on-year across the first four months of 2025, a shift that’s beginning to show structural signs.


The rate at which wind and solar are increasing means the rise in output from renewables now exceeds the rise in total demand (current running at +-3% per annum), even with electricity demand increasing because of EVs and PHEVs.   Which means, in turn, that China's emissions have peaked.  

Caveats:  growth may soar this year or next, or, for some inexplicable reason, wind and solar will stop growing.  Solar panels continue to decline in cost, and battery costs are falling even faster, meaning solar can be "firmed" easily and cheaply, so solar, at least, is likely to continue growing fast. 

  Note how wind and solar have different seasonal patterns, which means that, combined, less of both is required.  For now, gas will still be required to balance the grid when renewables are low, but the rise in EVs/PHEVs and falling capacity utilisation at coal power stations, means that China has passed peak coal and peak oil.   Since China produces +-25% of the world's emissions, that may mean that world emissions have also peaked.

Total solar installed doubles in 2 years

 From Kees van der Leun

After decades of solar PV deployment, the world crossed the 1 TW (a million MW) line in 2022. Just two years later, after adding 0.6 TW in 2024, we already crossed the 2 TW mark too!
#SolarPV #solarenergy #renewables

It took 22 years for cumulative solar installed to reach 1 terawatt.  It took just 2 years for the next terawatt.  And I expect over the next 2 years, another 2 terawatts of solar will be installed.  Total cumulated solar is doubling every two years.  

Why?  First, solar continues to plunge in price.  Second, how much solar you could have in your grid was limited because there's no solar at night.  But with storage costs plunging, that's less and less of a constraint.  Solar farms are already routinely built with 4 hours of co-located storage.  In a couple of years, that will be 8 hours.  

Note:  this is not new solar installed each year, though that is also growing exponentially.  It is the cumulative total of all solar panels installed.

Electricity generation is going to transition to zero carbon much faster than even I, an optimist, have been thinking.

60 gigawatts of new solar in China in Q1!




From Renew Economy


China’s National Energy Administration (NEA) announced over the weekend that [newly-]installed solar capacity increased by 43.4 per cent through the [YoY in the ]first quarter of the year, with nearly 60GW of new capacity added.

The NEA published its national power industry statistics for the first three months of 2025 over the weekend, revealing that total installed power generation capacity for the country had reached 3.43 terawatts, a 14.6 per cent increase from the same time last year.

The country installed only 9GW worth of new thermal generation capacity, but 59.71GW of new solar capacity and 14.62GW of new wind capacity.

Newly installed solar capacity increased by 43.4 per cent over the same period in 2024, while newly installed wind capacity increased by 17.2 per cent.

The strong first quarter for new renewable energy capacity comes off the back of a particularly strong 2024 which saw the combination of wind and solar generate 18 per cent of the country’s electricity, according to global energy think tank Ember

All sources of clean electricity combined to supply 38 per cent of China’s electricity in 2024, led by hydropower, which contributed 13 per cent. 
[At current growth rates, wind and solar will contribute 40% of China's electricity by 2030, while total non-fossil fuel generation will contribute +-60%]

According to Ember, China remains on track to boast at least 2,461GW of renewable electricity capacity installed by the end of this decade, doubling its 2022 figure, and with solar capacity nearly tripling its 2022 number.

“With decades of sustained policy support, China is now championing the global cleantech revolution, leading in both domestic deployment and world production across sectors like solar panels,” said Dr. Muyi Yang, Ember’s Senior Energy Analyst.

“While clean energy promises many benefits, realising them requires bold, enduring policy frameworks that transcend political cycles. China’s example highlights that the race to a sustainable future will be won by those who invest not just in technology, but in the patience and persistence to see their vision through.”
