The energy sector is likely to continue to diversify, in part because diversification is good for resilience and for financial management.  The Economist article notes:

Nearly half of last year’s investment was in developing countries, notably China, whose energy concerns have more to do with the near term than with future global warming. It worries about energy security, and it wants to clean up its cities’ air, made filthy partly by coal-burning power plants.

Sometimes lost in the discussion about cleaner energy is that climate concerns are not the only reasons to consider other resources. Cleaner air, more stable prices, and locally sourced energy can all be good reasons to consider renewable energy sources along side more traditional resources. Prices, are the big one, of course, but when it's close, other considerations can more easily be part of the analysis.  It appears we're approaching that point, which means more opportunity, along with more upheaval. That's why some of us like the energy business so much. If nothing else, it's usually interesting,
