Since 1995, David Fridley has been a staff scientist at the Energy Analysis Program at the Lawrence Berkeley National Laboratory in California. He is also deputy group leader of Lawrence Berkeley’s China Energy Group, which collaborates with China on end-user energy efficiency, government energy management programs, and energy policy research. Mr. Fridley has nearly 30 years of experience working and living in China in the energy sector, and is a fluent Mandarin speaker. Prior to joining the Lab, he spent 12 years as a consultant on downstream oil markets in the Asia-Pacific region and as business development manager for Caltex China. He has written and spoken extensively on the energy and ecological limits of biofuels. David is co-author with Richard Heinberg of Our Renewable Future: Laying the Path for One Hundred Percent Clean Energy (2016). David is a Fellow of the Post Carbon Institute.
What Will it Take to Avert Collapse?
In our view, at some point scientists and policy makers must begin discussing the one scenario that world leaders seem to want to avoid at all costs, i.e., managed economic contraction. The irony is that this scenario could reliably cut greenhouse gas emissions and is achievable without appeal to magic (CCS or decoupling).

Embodied energy: An alternative approach to understanding urban energy use
Everyone knows that it takes energy to produce anything. The energy used in mining, transport, processing, manufacturing, delivery, and disposal is “embodied” in every product we consume, from food to diapers to televisions and insurance policies. Our traditional way of looking at energy, however, highlights only current consumption, traditionally disaggregated into agricultural, industrial, transportation, commercial, and residential sectors.

Nine challenges of alternative energy
Unlike conventional fossil fuels, where nature provided energy over millions of years to convert biomass into energy-dense solids, liquids, and gases–requiring only extraction and transportation technolgy for us to mobilize them–alternative energy depends heavily on specially engineered equipment and infrastructure for capture or conversion, essentially making it a high-tech manufacturing process.
