Gas Cost

There is a lot of talk about getting off of dependence on oil. Though gas prices are going up, it is still not as expensive as what is payed in Europe. But, alternate energies come at a cost, too. Electric cars would save all sorts of gas, great. But we aren’t building any more power plants – no one wants one by them. So, limited amount of electricity means more outages and higher bills. How much will the increased electric bill be vs the higher gas bills?
Ethanol…less CO2 emissions, yeah (of course nitrogen based emissions are higher..and worse for the environment). As people are just discovering, there is only so much farmland. Every acre of farmland used for ethanol is one less for food (can we say food shortages or higher prices). Not to mention, how much energy is used creating the ethanol?
I am not saying that we shouldn’t try to have alternatives. I am saying people need to take off the rose-colored glasses and make a realistic comparison.
Thoughts?
