Here in the UK it seems to be getting windier with each passing year. If

There more alternative energy sources , there will not be one or two

Nuclear will be back for example in different forms like Thorium
reactors. Bio fuels geothermal power tidal power ,wave power and many
more locals solutions . And fusion is as alwa

But it's a solved problem in many countries fossil fuels are simply to
cheap in the U.S. .
Sweden for example have almost no fossil fuel power plants they are
basically for emergencies .
So 98% of the production is with a low carbon footprint already.
It's basically the transport sector that use
