Either the United States Department of Energy likes Carbonocracy, or we’ve just got some good timing. Shortly before we linked to this story in Bloomberg on the approval of the first United States commercial tidal power permit, the DOE released two reports that paint an encouraging picture of the long-term viability of tidal energy and its ocean-going companion, wave power. The Energy Department press release announcing the reports boasts that they “represent the most rigorous analysis undertaken to date to accurately define the magnitude and location of America’s ocean energy resources,” and given the overall dearth of mainstream information out there on ocean energy sources, they’re probably right.
In total, the reports estimate that when combined with hydropower and other water-based resources, tidal and wave could help to account for up to 15 percent of the US electricity supply by 2030. As we’ve been saying all along, while that won’t necessarily keep the lights on all by itself, when combined with growing solar and wind sectors, tidal and wave have the potential to add to a strong and expanding renewable energy portfolio. Of course, much of this depends on the ability of these early-stage technologies to attract enough private capital to get off the ground, which largely depends (at least in the initial stages) on continued federal support, which is not necessarily a guarantee.
Still, the DOE report is another indication of the United States’ vast potential to develop clean, home-grown energy (and attract that jobs that would come along with that development). 15 percent by 2030 sounds a long way off, but the decisions we make today will have a big impact on whether those figures constitute pure fantasy or legitimate reality tomorrow.
