History of Energy in 10 Minutes

Charlie Hall recently shared the link to the nice video below via his email blast. He even appears himself in the section on Energy Return On Investment (EROI). The description of the video: 

"All forms of economic production and exchange involve the transformation of materials, which in turn requires energy. Until recently cheap and seemingly limitless fossil energy has allowed many to ignore the important contributions from the biophysical world to the economic process and potential limits to growth.

The video that follows, commissioned by the United Kingdom's Department for International Development (DFID) and developed by the State University of New York College of Environmental Science and Forestry (SUNY-ESF) and Next Generation Energy Initiative (NGEI), examines the energy used by modern economies over time. This work centers on assessing the relation of energy costs of modern day society and its connection to the quality of human life. A focus of this video is energy return on investment (EROI) and some important characteristics of our major energy sources over time."
