Renewable energy technologies have made outstanding progress in the last decade. The cost of solar panels has plummeted. Wind turbines have become massively more efficient. In many places some forms of renewable energy are cost competitive. And yet…just as these exciting changes are taking place, the renewables movement seems to be shifting its focus to something that has little or no connection to the fundamental environmental goals: distributed generation, particularly at the residential level. In practice, this means rooftop solar PV.
Instead of seeking the most affordable way to scale up renewables, the loudest voices (though possibly not most of the voices) in the renewables movement are talking about “personal power”, “home energy independence”, “empowering the consumer”, and rejecting “government-created monopolies”. In the not so distant future, residential PV may be augmented with onsite storage (as suggested by Tesla’s announcement this week of its Powerwall home battery system).
