I see no downside in reducing or even ending our dependence on fossil fuels. This should have been done years ago.
Your inability to discern fact from fable is something I can't change. You deal in beliefs and feelings not logic.
Get out your bike and skates and you will be doing your part. Man's use of fossil fuels is goodness, not evil and ending our use of them isn't going to happen until there is a more efficient way to provide energy.
The downside is higher costs and less productivity and since you can't understand that, that puts you in the company of your fellow travelers, marx, lenin and hillary.
So what do we do when fossil fuel runs out? I want someone introduce a cleaner, cheaper fuel to the market and let the consumer decide.
We have to start finding alternatives NOW. Kennedy said he wanted a man on the moon by 1970 and it happened. When this country goes to work on something, it usually gets done.
There has to be a sane solution to the problem. We are too dependant on fossil fuels. I welcome to day that we can leave the middle east and let them turn it into a giant glass factory if they are so inclined.
