Some time in the future, Earth will run out of the fossil fuels available for producing energy.
Vaughn Nelson, a retired West Texas A&M University physics professor, stresses that point in “Introduction to Renewable Energy,” a textbook released this year that discusses how renewable sources can be used to help the world rely less on coal, natural gas and oil in the future.
The work in the textbook stems from lessons Nelson taught during a WT course on renewable energy last year, he said.
“As I told my students all along, the first thing is conservation and energy efficiency and the second priority is renewable energy,” he said. “We’re going to have to shift that way, especially given all the money we send overseas for imported oil.”
Nelson’s book is part of a much greater push to increase the use of energy from wind, the sun, water and biomass.
