We need new sources of energy for a whole variety of reasons, especially the fact that we're changing the climate (perhaps even driving it towards tipping points like permafrost melt and ocean acidification much more quickly than we thought -- indeed, NASA scientists say we now have less than ten years to act).
There is no simple answer to the question "How do we fuel our society sustainably?" Indeed, there probably isn't even an answer. Instead, we've got to be willing to explore a whole variety of technologies, approaches and business models, and to acknowledge that the answers change with the context. Wind turbines, for instance, make a lot of sense in California, with its well-established grid and coast-to-mountain winds, while distributed independent solar photovoltaics may make a lot more sense in the rural developing world. The best approach will be one which emphasizes diversity
What's called for is lots of research, open debate and investment. We need a decade or two of furious exploration, collaboration and competition.
We've written a lot about this issue, hundreds of articles, in fact, but here are some pieces we hope you'll find informative and thought-provoking:
