The plunging costs of renewables

From Information is Beautiful

 

Batteries were once the weak link. Solar and wind were clean but couldn’t keep the lights on after dark or when the wind dropped. 

Not any more.

Solar panels and battery storage have seen particularly spectacular reductions since 2010.

Battery storage is 93% cheaper than in 2010, making round-the-clock renewable power feasible and affordable. 

Cheaper technology spreads faster, which makes it cheaper still. 

That loop is now running in clean energy’s favour. 

Cleaner electricity is no longer necessarily the expensive alternative. In many markets, it's the economic choice.
