Three big utility CEOs agree: "there’s no issue with grid stability with deploying solar."

To sum up the so-called “intermittency and storage” problem for renewables: Geothermal has no intermittency issues and experiences fewer ephemeral shut downs than coal, nuclear, and natural gas. Solar thermal — with molten salt as its storage medium — can be designed to have no intermittency issues. Offshore wind yields power more or less 24/7 with relatively limited intermittency compared with onshore wind. The two most common sources of renewable electricity, onshore wind and solar photovoltaics, are, of course, complementary : wind turbines (which, in the case of GE, already have built-in storage capacity ) yield more power at night, while solar panels yield power during the day; hence, used in tandem, they can provide electricity 24/7 with “intermittency” being experienced only locally at each individual solar installation. The experience in Germany shows that the more...
