New Electric Car Charger: Consider the Source

Reposted from Discovery News

By Bruce Chapman

The Japanese have come up with a new electric car charger that can provide a Nissan Leaf (for example) a complete charge, good
for 200 miles, in only five minutes. It’s a potentially serious advance.

However, it is important with all these stories to note that energy
is still needed to CHARGE a car. You save gasoline (and its fumes) in
this process, but you don’t save net energy. If one lives in an area
that generates energy through hydropower, it’s all a plus; almost the
same with nuclear power; less so with natural gas; none at all or even a
minus with coal or oil.
