This week, a total solar eclipse crossed the United States for the first time in nearly a century. The eclipse dimmed the sun for several hours, leaving utilities questioning the impact on solar power generation and whether grids are prepared to handle state policies mandating a greater renewable energy mix. As solar output plunged along the route of totality, grid operators and utilities were forced to manage the drop by bringing on greater amounts of natural gas and hydro. Those states with high solar producing capacity, such as California and North Carolina, were significantly impacted by the path of the… [more]

Many people are hoping for wind and solar PV to transform grid electricity in a favorable way. Is this really possible? Is it really feasible for intermittent renewables to generate a large share of grid electricity? The answer increasingly looks as if it is, “No, the costs are too great, and the return on investment would be way too low.” We are already encountering major grid problems, even with low penetrations of intermittent renewable electricity, which in the U.S. was 5.4% of 2015 electricity consumption. In fact, I have come to the rather astounding conclusion that even if wind turbines… [more]
