So if the automotive industry moves toward electric cars, and most electricity is produced by coal. How is that a clean form of energy. How much carbon production will be reduced? Additionally, if 30% of fuel - gasoline - cost is taxes where will this new revenue come from in order to maintain the roads?
One last thing if the the Utilities pay the infrastructure cost for energy production and distribution and recoup that cost later, how are we truly going to switch to alt energy in 10 years? Who pays for the new infrastructure and what happens to the old stuff.
I am not an expert in your area of concern but would offer the following observations. I suspect the move to electric cars is occuring not to reduce carbon emissions (although that may be the result) but is more in response to consumer demand due to increased gas prices. Certainly a few would buy the electric cars because of the environmental ethic but most would buy to save a few dollars. You are probably correct that the use of coal for generating electricity will cause this all to be wash.
Perhaps an electric car can be designed that generates the power for the battery via solar cells on the roof. Although more envronmentally friendly, I would think the cost would be excessive. If, in fact, these cars are being built, not in response to an environmental concern but because they will now sell, then the increased cost using solar power versus coal would limit the sales.
I think it has an advantage and disadvantage..It is enviroment friendly yet expensive to have because the solar cells are highly expensive. By then its the consumers decision if they want to use that.
