Electric Cars Hurt the Environment
The U.S. and other countries have spent billions subsidizing electric cars,
an environmentalist solution which has been met with only lukewarm
enthusiasm from customers. And it turns out environmentalists are split over
whether these things are in fact worse for the environment than what we’ve
got. A new research paper from the Norwegian University of Science and
Technology has this to say (via The Guardian):
The study highlights in particular the “toxicity” of the electric car
’s manufacturing process compared to conventional petrol/diesel cars. It
concludes that the “global warming potential” of the process used to make
electric cars is twice that of conventional cars.
The study also says – as has been noted many times before – that
electric cars do not make sense if the electricity they consume is produced
predominately by coal-fired power stations. “It is counterproductive to
promote [electric vehicles] EVs in regions where electricity is produced
from oil, coal, and lignite combustion,” it concludes.
Making batteries for electric cars is a dirty process, and if the electric
cars are run off a grid which is primarily powered by coal, as it is in
China, the environmental benefits completely disappear.
Green jobs, green energy, green cars: the record of green public policy is
far more problematic than most environmentalists are willing to acknowledge.
Like the “peace activists” of the 1930s whose foolish policies helped
Hitler stage a bid for global mastery by disarming the democracies, green
activists today are often doing more harm than good.
The world needs better environmental policies; unfortunately,
environmentalists are often some of the biggest obstacles to clear thinking
and smart policy. The movement isn’t ready for prime time. | P*********0
