Also you need to carry along many hundreds of pounds of excess weight in the form of batteries which also consume space plus the expense of replacement and the pollution created in the manufacture and disposal of those batteries.
Well there is couple advantages to electric, firstly the coal supply and other forms of electric are firmly within the US borders. The combustion gas engine is not that efficient where as the process for burning coal and delivering electric is improving and has a lot of room for improvement, you're getting much more energy with less fuel being burned.
I read a study on gas powered lawn mowers Vs. Electric and the conclusion was the electric ones were much more environmentally sound. The only issue that the study raised was that overall the battery powered were probably the worse since they almost all used lead based batteries. One thing to keep in mind is that the gas powered lawn mowers had no pollution control. I haven't really researched it but I'll bet the same holds true for gas powered car vs electric car. Not only that but if it's from coal plant it's one single source of emissions to deal with instead hundreds of millions of them.
Personally I think all this technology is inevitable, there nothing wrong with it but I think they are jumping the gun with all these mandates. The one major issue I have is by adding all this stuff you're adding whole lot more stuff to break especially with the hybrids. The cost to repair these cars is going to be significant and the day of the neighborhood gas station where you can get reasonable rates is going the way of the dodo bird.
