Two new papers examine how turbine-atmosphere interactions shape wind-power’s environmental impacts

By David Keith

Today Lee Miller and I published a pair of papers on the interaction between wind turbines and the atmosphere. “Observation-based solar and wind power capacity factors and power densities” in Environmental Research Letters, and “Climatic impacts of wind power” in Joule. (Many thanks to the journals for arranging simultaneous publication.) Don’t miss Lee’s video abstracts for Joule and ERL....

Why we chose not to patent solar geoengineering technologies

By David Keith and John Dykema

We broadly oppose commercial development solar geoengineering. In our view, a central objective of solar geoengineering research is to develop credible assessments of its risks and efficacy. Credibility depends, in part, on confidence that the risks of solar geoengineering are not concealed, that its effectiveness is not exaggerated. Such credibility can, in our view, be best generated by a transparent multipolar research effort. Where, “transparent,” means open access to the full research process, including raw data, dead ends, and experimental failures. Where “multipolar” means the research is conducted by a diversity of independent entities including research by groups that focus on finding the ways that it will fail....

Climate Impacts of Biking vs. Driving

Paleo-diet cyclists warm the planet as much as Prius drivers — but under the usual (but crazy) assumption that nothing matters beyond 100 years in the future
