This could be an fruitful area of research.  We tend to look at the pros and cons of each type of renewable energy in isolation and each is found wanting in some way, usually for its intermittence or unpredictability.  Much more useful would be a serious search for the right mix of renewables to best meet our needs.

"For a more distant future,  the balancing of solar and wind is another issue: intriguingly, the day/night and weather patterns of these can be combine to give not a constant power, but one roughly following the daily human usage curve!"

I find this idea very interesting.  I would be grateful for any links you might have.

We all bleed the same color.
