In Denmark, greener is better

In Denmark, political parties are fighting over which has the greenest policies.  What a nice problem to have.  In Australia, the ruling "Liberal"/"National" coalition has just been re-elected after a scare campaign about how much the opposition Labor Party's emissions reduction plans would cost.  The L/NP has no plans to cut emissions.  Indeed, it wants to subsidise coal power stations.  Peak stupid.  Or Venal.

 Actually, Denmark is on track to dramatically cut emissions, whoever wins the Danish elections.  For example, by 2026 Denmark will have zero emissions from electricity generation.


Wind should produce 70% of total generation, and solar 20%.



But more electricity will be needed to power electric cars.  Eliminating natural gas and coal will require only 61% wind, even without solar.  If EVs increase electricity demand by 30%, the expansion of wind and solar will ensure there is enough power even without fossil fuels.  And remember: an EV stores a few days' worth of household electricity demand, so EVs will balance the grid.  Electricity pricing will be adjusted to encourage charging when electricity is surplus, and discouraging it when supply is tight. 

A 100% carbon-free economy.  And its political parties are vying with each other to make it happen faster!  Cause for hope.


Nuclear and hydro are imported.
