> utilizing or selling "free" energy from fossil fuels? Companies extract these, they often don't pay for the energy (just the cost of extraction)

Is "solar" and "wind" energy not free in the same sense?

Also: are the balancing costs of the network paid by those people selling the "free" renewable energy? As I see they often don't pay for that (not to mention the pollution that causes, which is still not paid by any energy producer)
