Dan mentioned a few places to go deeper with any of the energy issues brought up during his talk. First and foremost, Dan said just Google it. If there is a particular energy issue you want to learn about, google it + your city and you’ll find it.
Dan also highlighted the biggest problem, in his opinion, facing us globally: poverty. A few of the links below are groups working locally on the connection between poverty and environmental justice.
Latino Issues Forum
Ella Baker Center
Environmental Entrepeneurs
Environmental Defense - Take Action
ICLEI - Local governments for sustainability

Popular Mechanics did an interesting fiscal analysis of various gasoline substitution technologies. Even though the only ethanol source listed is from corn, the analysis illustrates how conventional gasoline still tops the charts. Many technologies were compared including E85/ethanol, M85/methanol, B100 biodiesel, compressed natural gas, electricity (EV cars), and Hydrogen fuel cells.

Don’t let the table fool you, each of the potential fuels above is fret with problems. The greatest potential for widespread use lay with 2: biodiesel and ethanol. Why? Infrastructure change is highly expensive and these require the least amount of change.
