We (well, at least in the UK) have plenty of them. It's all that tricky, expensive, and financially unrewarding infrastructure that's holding things back.
We pay Scottish windfarms about £200million per year to curtail their output, just because we can't get the power from source to sink.
So it's easy to throw up some wind turbines and solar panels, but difficult, expensive, and requires cutting-edge technology to make them useful as power sources to the national grid?
If modern renewables are so affordable as investments, provide quick returns, and produce electrictiy that's 30% the cost of nuclear, then why isn't it everywhere and electric power very cheap?
