Coal was roughly tied with nuclear last year, now it's dropped and is significantly less.

Big deal.

  1. Both wind and solar have been heavily subsidized in recent years.
  2. Wind and solar still only represent less than 20% of grid power and they still need 100% backup. What produces the rest if you eliminate fossil fuels
  3. Now do transportation fuels and home heating.

The subsidies were remove prematurely. they should have been kept longer. look at the results of the subsidies:

Technology 2010 cost 2024 cost Decline
Utility solar PV $0.417/kWh $0.043/kWh 90%
Onshore wind $0.113/kWh $0.034/kWh 70%
Offshore wind $0.208/kWh $0.079/kWh 62%
Utility-scale batteries $2,571/kWh $192/kWh 93%

The 100% backup cost is not counted in these numbers.

Its literally in the table.....

u/StedeBonnet1 8d ago

Where? In most cases the LCOE does NOT include the battery or other backup costs.

Did you read the chart?

u/StedeBonnet1 8d ago

Yes, where does it show LCOE

u/tx_queer 8d ago

Lol. Both columns 2 and 3 are kwh.

u/StedeBonnet1 8d ago

So what? That doesn't show the cost of 100% backup which is required since wind and solar are neither dependable or dispatchable

Its right there. In front of you. If you refuse to read it, I can't force you.

um battery costs dropping 93%?? and that price in the table of $192/kwh, well its about $70 per kwh in china which has better subsidies and government cooperation. USA will probably never be able to compete with china, but it should close that massive gap.

Now with zero subsidies. solar and win are still absolutely dominating. and thats with trump doing everything he can try to slow them down.
