Well it is because it depends on heavy industry to manufacture it. I'm curios, are there stats on the energy that goes into manufacturing a windmill + battery setup vs the expected energy output over the lifetime?
In other words, are they at least self sustaining? Haul trucks and crushers for mining take massive amounts of energy that are currently being driven by fossil fuels. So renewables are subsidized by fossil fuels and the question is how much?

Wind turbines are pretty simple, cheap, and tend to last a while. https://en.wikipedia.org/wiki/Energy_returned_on_energy_invested https://en.wikipedia.org/wiki/Energy_returned_on_energy_inve...
