It's kind of sad that we stop talking about alternative forms of energy when gas prices are down.  A few years ago when gas prices were in the $4 range, there was always a story about how to reduce it, how to buy a hybrid, etc. People complained. Hummers stopped being popular. Hybrids were the thing. Everyone called for better mileage. Now, not everyone cares so much, but this shouldn't stop us. There are millions of cars available today and you have the choice and the power to decide what is best for you, but what is also best for the environment.
