Electric cars be not so eco-friendly

A latest report has claimed that an increase in electric cars is probable to lead to more electricity production from coal, gas and nuclear plants, without necessarily reducing oil demand for conventional cars

Putting more electric cars on the road may increase CO2 emissions, three foremost environmental lobby groups said on Monday - issuing a warning to the European Union as it prepares to maintain the new technology.

Electric cars are seen as a way for European car producers to improve their green credentials and build up a technology that would permit them to keep in front of the competition. European governments, sequentially, expect this would allow them to reverse a trend of job cuts in what is currently an ailing industry.

Though, a report by Dutch consultancy CE Delft, backed by Greenpeace, Friends of the Earth Europe and Transport & Environment, claims that "under current policies, an increase in (electric cars) is probable to lead to more electricity production from coal, gas and nuclear plants, without essentially reducing oil demand for conventional cars." The three groups call for the abolition of so-called super-credits in the EU's laws on car emissions, which permit manufactures to add up electric cars as zero-emission vehicles, serving them meet generally pollution targets for their entire model line-up.

Unless current rules are altered, the report claims, growing sales of electric cars "may then lead to abridged efforts to improve the energy efficiency of conventional (...) cars with the result that (they) will possibly not reduce oil consumption and CO2 emissions in the transport sector." EU industry ministers are set to meet on Tuesday in San Sebastian, Spain, to endorse an action plan for the development of electric vehicles. The plan was presented in January as a top precedence for Spain’s EU presidency, planned to run until June 30.

The CE Delft report says that CO2 emissions over the whole car production chain — the so-called 'well-to-wheel' cycle — would increase if electric vehicles were to be powered by lignite-derived electricity.

They would fall "significantly" if gas-fired power plants were used instead, and be abridged to "near zero if carbon-free renewable energy (were to be) used." The environmental groups, consequently, want the EU and national governments to make sure electric cars are charged with electricity produced from renewable energy sources, for instance wind and solar power.
To accomplish this, they propose fitting 'smart meters' that would automatically identify 'renewable energy' to every electric car.

We need elegant electric vehicles that cooperate with smart electricity grids so cars can blame up on green power. Dump electric vehicles plugged into a dump electricity grid would merely add demand for coal and nuclear power and drive us away from a sustainable energy future, said Greenpeace's Franziska Achterberg.
