Hybrids are they really good for the enviroment?

I agree we need to get more fuel efficient cars, but are hybrids the way to go? I mean they use some type of nickel batteries, which are terrible for the environment when made and eventually disregarded. The product lifestyle for a hybrid is less than a regular care because the batteries go bad around 100000 miles. Furthermore their gas mileage is not phenomenally better than regular cars, realistically they get about 40-45mpg, while regular cars can now get 30 maybe 35.
With the electric car it again uses batteries, and electricity. Many assume that because they use electricity they are automatically green. However whats the number 1 way of producing electricity in the USA, coal, gas, nuclear, does that not defeat the purpose of an electric car? I must admit an electric motor is highly more efficient than a combustion.
People are talking about ethenol, but how much work does it take to grow, harvest, and produce it.
Everyone needs to look at all the benefits and shortcomings to every technology, from production to destruction.
Basically their is no silver bullet for our energy needs. What we need is another Manhattan project for energy.
