An
alternative to the internal combustion engine is gaining in popularity,
especially with rising gas prices. That alternative is the electric car. Back in 2009, President Obama, along with
Congress decided to include a $7500 tax credit to those that chose to purchase
an electric vehicle. In Oregon, Governor Ted Kulongoski included a $1500 tax
credit.
While
the electric car seems like a practical alternative (other than say, public
transportation and “human powered” bicycles), there may possibly be some downsides.
While it’s convenient for an electric car owner to plug their car into an
outlet in their garage at night, they would be less damaging to the environment
if the energy used to charge them came from renewable sources such as wind,
solar and hydroelectric sources, but that’s not the case. In Oregon, home to a
world-renown hydroelectric system, the electricity needed at night would most
likely come from coal plants, which happens to be one of the dirtiest sources
of energy.
There
is debate on whether or not electric cars would be contributing to greenhouse
gas emissions. Some say that using an electric car, even while being charged by
a coal powered source would reduce greenhouse gases by one quarter, but others
say that unless coal gets cleaner the benefits are negligible.
There
are more environmentally friendly alternatives out there, including cellulosic
biofuel, which is made from garbage, switchgrass and wood waste and could cut greenhouse
gas emission in half. Another
alternative is hydrogen fuel cells, which, depending on how it’s produced can
cut greenhouse gases further.

Oregon's one and only coal plant (Boardman) is currently scheduled to be closed. http://www.oregonlive.com/business/index.ssf/2010/04/pge_files_to_close_boardman_co.html
ReplyDeleteElectric cars can be powered renewable energy. The solar panels on my house create enough energy for 19,000 miles of electric car driving annually.
You mention several other alternatives. Some of these have promise, but battery powered cars are possible right now. They can reduce fossil fuel use, foreign oil imports, CO2 pollution...
Interesting. I hadn't heard this claim before. Electricity to affect thermal coal? I would be interested to hear any evidence which suggests it does. Angie www.coalportal.com
