The wind turbine can't extract any energy without slowing the wind down

What I was getting at is that after flowing around wind turbine the air
will have less energy and apparently will also be more turbulent. So be
it. However, I really don't think understand just how incredible an
energy source fossil fuels are, regardless of their terrible downsides.

There more alternative energy sources , there will not be one or two
dominant solutions in the future as it is now .
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

Solar and wind generation plants are already cheaper to build than
fossil fuel plants. The fuel is free and environmentally friendly. What

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
