Futurology

Every region will have renewable/clean energy that is better suited to it. Investing in many approaches and deploying them where they're most effective is definitely the right approach. Alaska would be terrible for solar, but I imagine this solution wouldn't have anywhere near the amount of seasonal fluctuation. My only concern would be the potential effects on marine life, though I'm sure it would be far less than the heating and accidification of the oceans due to emissions.
