Excellent uplifting article – read the full story (link at bottom). This map shows a path that creates twice as many jobs, while improving health conditions and our climate.
“by eliminating oil, gas, and uranium use, the energy associated with mining, transporting and refining these fuels is also eliminated, reducing international power demand by around 13%. Because electricity is more efficient than burning fossil fuels, demand should go down another 23%.
100% renewable energy
The latest roadmap to a 100% renewable energy future from Stanford’s Mark Z. Jacobson and 26 colleagues is the most specific global vision yet, outlining infrastructure changes that 139 countries can make to be entirely powered by wind, water, and sunlight by 2050 after electrification of all energy sectors. Such a transition could mean less worldwide energy consumption due to the efficiency of clean, renewable electricity; a net increase of over 24 million long-term jobs; an annual decrease in 4-7 million air pollution deaths per year; stabilization of energy prices; and annual savings of over $20 trillion in health and climate costs. The work appears August 23 in the journal Joule, Cell Press’s new publication focused on sustainable energy.
These analyses have also been criticized for the massive investment it would take to move a country to the desired goal. Jacobson says that the overall cost to society (the energy, health, and climate cost) of the proposed system is one-fourth of that of the current fossil fuel system. In terms of upfront costs, most of these would be needed in any case to replace existing energy, and the rest is an investment that far more than pays itself off over time by nearly eliminating health and climate costs.
“It appears we can achieve the enormous social benefits of a zero-emission energy system at essentially no extra cost,” says co-author Mark Delucchi, a research scientist at the Institute of Transportation Studies, University of California, Berkeley. “Our findings suggest that the benefits are so great that we should accelerate the transition to wind, water, and solar, as fast as possible, by retiring fossil-fuel systems early wherever we can.”
