Renewable microgrids in Alabama, India and South Africa and solar net metering’s effects on utility business models and rates are highlights of this past week’s distributed clean energy news.
I got into renewable energy in the 1970’s, partially in response to the prospect of an expansion of nuclear power. I was videotaped by CBS News at Seabrook asking people to hire me to chop wood for them rather than support nuclear power. Then Three Mile Island happened and for 3 decades it looked like the nuclear power industry was dead. We got complacent and worried more about peak oil and climate change. […]
The first true “smart grids” are already being built, but they aren’t where you would expect. It is not Boulder Colorado’s much-hyped SmartGridCity, built by Xcel at a cost of $140 million dollars. That is little more than a collection of smart meters and a fiber optic network. If you want to see a smart grid today with distributed load control, energy storage, and extremely high penetrations of renewable power you need to […]

If the world is going to transition to a sustainable energy future, then renewable energy must eventually supply more than a 20% share of the power sector. However, large utility companies are very frank about their lack of understanding of how to integrate solar and wind power at those higher levels. That is why they continue to propose large coal plants. Utility systems can indeed have much higher shares of renewable power, as […]
