But there is free energy in the wind that can obviously be harnessed. The harnessing isn’t free, but the energy is.

???????????????????????????????????????
It costs more for electricity generated form wind than conventional but the wind is free? Coal is free but the harnessing isn't. Nuclear is free but the harnessing isn't. weirdo green ideas are free but the harnessing of them is the most expensive.

If you want green energy there’s nothing cheaper than hydroelectric. Fortunately my state is relaxing the regulations for retrofits on hundreds of dams in the state.

Its like anything else, cost effectiveness is related to availability.
