U Chicago, MIT study suggests ongoing use of fossil fuels absent new carbon taxes

Green Car Congress

A paper by a team from the University of Chicago and MIT suggests that technology-driven cost reductions in fossil fuels will lead to the continued use of fossil fuels—oil, gas, and coal—unless governments pass new taxes on carbon emissions. for oil, 24% for coal, and 20% for natural gas.

False Starts: The Story of Vehicle-to-Grid Power

Cars That Think

They wanted to see whether an electric vehicle could feed electricity back to the grid. The concept behind V2G had gained traction in the late 1990s after California’s landmark zero-emission-vehicle (ZEV) mandate went into effect and compelled automakers to commercialize electric cars. AC Propulsion’s experiment was timely.
