VISION-2050 (100% RENEWABLE)

Scientists have revealed an in depth road map to maneuver 139 countries to 100% renewable energy by 2050, in keeping with a recent study.

Energy specialists at Stanford University according that using wind, solar, geothermal and water (hydropower, tidal and wave) energy to electrify all economic sectors that require power to control — as well as the electrical grid itself, transportation, heating and cooling, industrial, and therefore the agriculture, forestry and fishing industries — would considerably reduce energy consumption, decrease deaths from air pollution, produce a lot of jobs, stabilize energy costs and save trillions of dollars on health care and climate-related prices.

"We have individual plans for each of the 139 countries, and these represent more than 99 % of all of the emissions worldwide," Mark Jacobson, director of Stanford University's Atmosphere and Energy program, told Live Science. [Top ten Craziest Environmental Ideas]

The study checked out the world's energy wants, starting with 2012 and projected resolute 2050. In 2012, the world used 12.105 terawatts (TW) of energy that is up to 12.105 trillion watts. By 2050, the world can want 20.604 TW if nothing changes and each country continues with identical approach it presently uses to fulfill energy demand, the researchers wrote in the study.

But if those same business sectors were to show to renewable energy sources to electrify their all of their power necessities, the world would want simply 11.804 TW to fulfill world power demands, in keeping with the study. This can be as a result of electricity is a lot of economical than combustion, according to the researchers.

In a video explaining the main points of the study, Jacobson offered an example: In an electrical car, he said, 80 to 82 % of the electricity used goes toward moving the car; the remainder is wasted as heat. During a gasoline-powered vehicle, on the opposite hand, only 17 to 20 % of the energy within the fuel goes toward moving the car, and also the rest is wasted as heat, he said.

Energy is additionally required to mine, refine and transport fossil fuels. As such, switching to 100% renewable energy would eliminate these energy-intensive and environmentally harmful processes, the report authors said.

Still, there are ways that to resolve the problem, he said. These regions might turn to offshore wind energy, or they might exchange energy with a neighboring country, he added.

"With this info, we're giving confidence to countries that they'll be independent," Jacobson said. "I'm hoping that totally different countries can plan to 100% renewable energy [by 2050] and 80% by 2030."
