Renewable Energy: the Time is now

“The use of vegetables oils for engine fuels may seem insignificant today but such oils may become in the course of the time as important as the petroleum and the coal tar products of the present time”

“The fuel of the future is going to come from fruit like sumac out by the road, or from apples, weeds, sawdust-almost everything”

“I’d put my money on the sun and solar energy. What a source of power! I hope we don’t have to wait until oil and coal run out before we tackle that”

Rudolph Diesel 1912

Henry Ford 1925

Thomas Edison 1931

Even if it was not the Time then
