The article I read, says that CO2 emission of electric and fossil fuel cars are neck and neck. However, the article did not take into account several important factors. 30% of electric power generation in the US is from non-fossil fuels, primarily, nuclear and hydroelectric which have essential zero emissions. Secondly,the emissions due to transportation of the fuel to power plants is much less than the transportation to service stations, particular transportation of natural gas.Posted an RT video on that earlier, if an electric car gets energy generation from coal (or other non-renewable source) then it produces more carbon emissions/pollution into the atmosphere than a fossil fuel vehicle. Most countries use non-renewables, so it would be a stretch to suggest that electric cars would be 'better for the environment', as even many European countries can't reach current electricity demands without fossil fuel generation.Your post brings up the question of co2 emissions due to fossil fuel electric power generation to power an electric vehicle versus emissions from fossil fuel used to power a gas vehicle. Would there be more or less co2 emission from a gasoline vehicle driving say a hundred miles or from the fossil needed to generate the electricity to power an electric vehicle driving that distance?However, the market is barely keeping pace with current projected electricity needs, any increased use is bad for the environment and will make it difficult to meet 'green energy' targets. What electric cars will lead to, is more non-renewable power and coal or gas plants.Still too expensive when compared to gas vehicles, and 2017 is too far away.
The ultimate test will be how many they sell in comparison to hybrid cars, but I doubt they will out sell them or change the market.
The EV market will continue to grow. Generating electricity will also grow. The renewable generation of electricity has come a long way, and will continue to do so.
As the need grows, so will the need for nuclear power plants. Properly run they are our best option right now.
yeah it is a good thing however windmills and solar panels do not do much
for demand times
we need many more nuke plants but good luck getting that through
But another point to be made is how would electricity companies possibly build the required capacity to keep up with out of control energy demands, as in this hypothetical near future (where every car is standard electric and not hydrogen fuel cell). The answer is four options:
A) Increase electricity prices to pay for the new infrastructure, possibly by 100% or more given the massive energy demands.
B) Only add infrastructure as required or when new plants can be budgeted, resulting in big power outages only usually seen in third world countries.
C) Heavily subsidize electricity companies, out of the taxpayers pocket in state and federal taxes. Expect everyone's taxes to increase by 20% or more. This would create an oversupply, but high power bills would be paid in taxes.
D) A combination of all three.
If we were faced with electric cars claiming a large portion of the market in the near future, generating capacity would be a big problem but that's not the case. Using current sales figures, in 20 years, electric cars would account for only a half of one percent of the cars on the road. That is certainly not going to create a power shortage. Lastly, new power plants coming on line are more efficient at generating power and reducing emissions.
