Renewable energy could by 2050 an 80% of our total use. This would be great for our environment and us. Still there is a long road ahead that we must cover. Back in the 1800's we had electric cars. Edison was a big investor, but oil companies stepped in. They pushed gasoline and diesel fuel as better for our economy. Windmills were common in rural areas. Coal burning generators were pushed by energy companies. Today over 50% of our electricity comes from coal and the percentage is going up. People need to understand energy execs. All they want is to make more money. Sadly, this is the cause of our lack of energy resources. OK my solution is wind power generators and electric cars.
