Environmentalists have an honest concern over the welfare of our planet but I don’t think we all realize the energy consumption of our nation. This one statistic of roughly 400 million gallons of gasoline a day is mind boggling. And this is just one product. I can’t even begin to fathom the amount of all the other products. So, yes lets keep switching to cleaner energy as long as we don’t punish the consumer with shortages and higher costs.
