Wind+solar+storage = full grid power by 2030

Wind, solar power paired with storage could be cost-effective way to power grid – Recent research from the University of Delaware and Delaware Technical Community College says this can be done by 2030 at costs comparable to today’s.  The study drew on data from 13 states, about one fifth of the U.S.’s current electrical grid.  Via Clean Technica.

“The key is to get the right combination of electricity sources and storage — which we did by an exhaustive search — and to calculate costs correctly.”  …

The study used estimates of technology costs in 2030 without government subsidies, comparing them to costs of fossil fuel generation in wide use today. The cost of fossil fuels includes both the fuel cost itself and the documented external costs such as human health effects caused by power plant air pollution. The projected capital costs for wind and solar in 2030 are about half of today’s wind and solar costs, whereas maintenance costs are projected to be approximately the same.
