Are Electric Cars Really Green?|5 Minute Video
Are electric cars greener than standard gasoline cars? If so, just how much greener? What about the CO2 emissions produced throughout electric cars and trucks’ production? And where does the electricity that powers electric cars originate from? Ecological economist Bjorn Lomborg, director of the Copenhagen Consensus Center, examines how eco-friendly electric cars truly are.

Script:
Do electrical automobiles truly assist the environment? President Obama thinks so.
The argument goes like this:
Regular automobiles run on gas, a fossil fuel that pumps CO2 straight out of the tailpipe and into the environment. Electric cars and trucks run on electrical energy. No gas; no CO2.
More than a 3rd of the life time carbon-dioxide emissions from an electric vehicle comes from the energy utilized make the car itself, particularly the battery. When an electric cars and truck rolls off the production line, it’s already been accountable for more than 25,000 pounds of carbon-dioxide emission.
That’s not the end of the CO2 emissions. Since while it’s real that electrical cars don’t operate on fuel, they do operate on electrical energy, which, in the U.S. is typically produced by another nonrenewable fuel source– coal. As green venture capitalist Vinod Khosla likes to explain, “Electric cars and trucks are coal-powered automobiles.”
The most popular electric car, the Nissan Leaf, over a 90,000-mile life time will emit 31 metric lots of CO2, based upon emissions from its production, its electricity usage at average U.S. fuel mix and its supreme scrapping.
A comparable Mercedes CDI A160 over a similar lifetime will release simply 3 lots more throughout its production, diesel intake and ultimate scrapping. The results are comparable for a top-line Tesla, the king of electric cars. It releases about 44 lots, which is just 5 tons less than a comparable Audi A7 Quattro.
Throughout the complete life of an electric cars and truck, it will discharge simply 3 to five lots less CO2. The U.S. federal government essentially supplies electric automobile purchasers with an aid of up to $7,500.
Paying $7,500 for something you could get for $35 is a very bad offer. Which doesn’t include the billions more in federal and state grants, loans and tax write-offs that go straight to battery and electric-car makers
The other primary gain from electric automobiles is supposed to be lower pollution. But remember Vinod Khosla’s observation “Electric vehicles are coal-powered cars.”
Yes, it might be powered by coal, supporters will state, but unlike the routine cars and truck, coal plant emissions are far from the city centers where most people live and where damage from air pollution is biggest. Brand-new research study in Proceedings of the National Academy of Sciences found that while gas cars and trucks contaminate closer to home, coal-fired power in fact contaminates more– a lot more.
