Climate Impacts of Biking vs. Driving

By Daniel Thorpe with help from David Keith

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

See our free course on edX that debates issues like this and teaches you how to do the kinds of research and calculations in this blog post.

NOTE #1: this is a back-of-the-envelope estimate of the marginal impact of biking or driving a Read more about Climate Impacts of Biking vs. Driving

Cheap Solar Power


Over the last few years solar PV has got cheap. Cheap enough to start impacting some commodity energy markets today. Cheap enough that with continued progress, but no breakthroughs, it might alter the global outlook for energy supply within a decade.

I have long been skeptical of solar hype. In 2008 we did an expert judgment exercise suggesting only even odds of getting to module prices of 0.3 $/W in 2030. In 2011  Read more about Cheap Solar Power

Harvard Grants for Solar Geoengineering

The Keith Group is grateful to have been the lead recipient of three grants from internal Harvard programs over the past few months: The Star Family Challenge for Scientific Research, The Weatherhead Initiative Research Cluster in International Affairs, and The Harvard Climate Solutions Fund. We thank these generous programs for funding research on a variety of important topics related to solar geoengineering. Grants with a total value of 450 $k (without overhead) will enable researchers to address key scientific and governance questions surrounding solar geoengineering:
