Detailed plan outlines total global conversion to renewable energy sources
By Summit Voice
SUMMIT COUNTY — Most of the world’s energy demands could be met from renewable sources within the next 20 to 40 years — without waiting for a technological magic bullet, according to a pair of California researchers who said the only obstacle is the lack is the political and social will.
The study was co-authored by Stanford University’s Mark Z. Jacobson and Mark Delucchi, of the University of California-Davis. It outlines the costs, technology and material requirements of a complete conversion to renewable energy sources based on a plan they developed. The researchers approached the conversion with the goal that, by 2030, all new energy generation would come from wind, water and solar, and by 2050, all pre-existing energy production would be converted as well.
“Based on our findings, there are no technological or economic barriers to converting the entire world to clean, renewable energy sources,” said Jacobson, a professor of civil and environmental engineering. “It is a question of whether we have the societal and political will … We wanted to quantify what is necessary in order to replace all the current energy infrastructure – for all purposes – with a really clean and sustainable energy infrastructure within 20 to 40 years,” Jacobson continued (more…)
