The Futility of Hybrid Cars

BY Janet Crain

The widespread adoption of hybrid cars needs a good hard look at its ability to cut greenhouse emissions , etc. This is not likely to happen under an Obama administration and by the time he is out, things may be so screwed up we will have squandered all our resources chasing after this mirage.

Could plug-in hybrid cars actually increase greenhouse gas emissions? Is energy efficiency being oversold as a greenhouse gas reduction measure? A new report from the research arm of Congress raises troubling questions about the direction in which President Obama is taking us.

Produced by the Congressional Research Service (CRS), Carbon Control in the U.S. Electricity Sector: Key Implementation Uncertainties provides the lowdown on a variety of carbon control options for the electric power sector, including energy efficiency, renewable energy, nuclear power, advanced coal technology, carbon capture and sequestration, plug-in hybrid vehicles and small-scale power generation technologies.

President Obama has proposed that we reduce our CO2 emissions to 1990 levels by 2020. For the electric power sector, this goal translates to reducing what is projected to be 2.6 billion metric tons of CO2 emitted in 2020 to approximately the 1.8 billion metric tons of CO2 that were emitted in 1990 -- a more than 30 percent reduction in emissions over a period of about 10 years.

Could this goal be achieved through gains in energy efficiency? Numerous private and government sources have claimed, after all, that 25- to 30-percent gains in efficiency are possible over a 5- to 15-year time horizon. But according to the CRS, “the diffuse nature of efficiency opportunity and the economic complexity of decision making” has historically made moving beyond the 5 percent to 7 percent electricity savings range “a persistent challenge to conservation proponents.” Although more aggressive policies could be attempted, the CRS says, there is “little track record upon which to base projections of future effectiveness.”

The CRS report cites sources that say a significant increase in biofuel production “would require harvesting various energy crops at a scale that vastly exceeds current practice.” A 2007 study from MIT estimated that as much as 500 million acres of land would be required, which would displace so much cropland that the U.S. would have to become a “substantial agricultural importer.”
