Stanford researchers roadmap leads to 100% renewable energy in 139 countries

A team of researchers at Stanford University have published a study which paths a roadmap to the powering of 139 countries across the world entirely from renewable energy sources by 2050.

The study describes a future where nations including the US, China and the UK have electrified their energy sectors, allowing them to run 100% on solar, wind, hydropower and geothermal energy sources.

A complete transition away from fossil fuels within these countries could lead to a net increase of 24.3 million long-term full-time jobs, an annual decrease of up to 7 million deaths from air pollution and could crucially prevent a global warming of 1.5 degrees Celsius.

“The roadmaps are not a prediction of what might happen,” said the research team led by Professor Mark Jacobson.

“They are one proposal for an end-state mix of wind, water, sunlight (WWS) generators by country and a timeline to get there that we believe can largely solve the world’s climate change, air pollution, and energy security problems.”

The study was a follow-up to a controversial research report in 2015, which suggested the US could switch to 100% renewable energy by 2050.
