The transition to a 100 percent renewable energy grid is a major undertaking. If implemented, it will have a dramatic impact on the economy and jobs. It will also help reduce pollution and air pollution deaths.
Many countries are pursuing this goal, including the US, Canada, China, India, Sweden and Norway. In Germany, the new government has announced a reform that will see 80% of the country’s power needs generated by renewable sources by 2030.
There are also several studies that are being done that aim to help guide the transition to a 100 percent renewable energy world. These studies show the positive impacts of such a change, outline the development of the renewable energy sector, and outline roadmaps for individual countries.
A study released by Stanford University and the University of California at Berkeley has produced a roadmap for a global transition to 100% renewable energy. According to the researchers, the global demand for energy could be reduced by almost forty-two and a half percent. This would help to avoid global warming by as much as 1.5 degrees Celsius.
Several large population regions, such as Iceland and Costa Rica, are currently at or near 100% renewable. They get their electricity from solar, geothermal, hydropower and wind.
Almost 100 cities in North America are already at or near 100% renewable. Spain, Portugal, Austria, Ireland, New Zealand, and the South Island of New Zealand are at or above the 100% mark.
