The end result of solar/wind is that the cost per KWH is significantly higher than any other source that we know of. My brother had access to a local wind power company's balance sheet. According to him, it would take 70 years to pay back the cost to install and maintain the plant if they were to sell the power at current market rates.
Not only that, most solar we talk about (in the US) is solar thermal, and not just solar panels. Solar thermal generates a lot more power per square foot, which is somewhat more economically viable than solar panels, but such systems require massive re-distribution of water which in and of itself is a major ecological concern.
Back from the dead, I'm afraid.
