Srsly what do u expect? Do you know how expensive a bunch of windmills and solar panels on god knows how much land is?

UKP 1,125/kW all in for wind turbine

Land area per home for a solar farm is 645 square feet. On a rooftop the same installation needs about 300 square feet because you don't need space between rows like a solar farm. Rooftop installations don't use more land since the house is already there.

Enough solar farms for all 25 million UK residences would take up 578 square miles. You wouldn't build that much because there are other renewable sources. If you did, the UK's land area is 94,000 square miles, so about 0.6%

Agrisolar is dual-use of land for solar and agriculture. A common example is grazing sheep under the panels. That reduces the net land usage.

Land-based wind turbines consume about 1% of the wind farm's area, for access roads and the turbine base. They are compatible with other land uses, like farming. Offshore wind turbines consume no land area, of course.

That doesn't include decommissioning, or the cost for backup energy when the wind isn't blowing as much.

You need to look at system cost, not LCOE.

Fuck all compared to every other form of power generation.

I’ll never understand you people, so fucking arrogant that with two seconds of “thinking” you somehow have the impression you’ve come up with pricing problems nobody who actually works in the industry has ever noticed
