What would a more sustainable world powered by renewable energy look like? We have a better sense, thanks to a special collection of research from experts from around the globe.
Collated by Stanford University, a collection of 47 peer-reviewed research papers by 91 authors analysed different scenarios to examine whether individual countries or entire regions could get by solely relying on renewables.
The papers look at a range of different situations and geographies, including small island states, major powers and countries in sub-Saharan Africa. In each case, they found energy for electricity, transport, building heating or cooling, and industry can be supplied reliably with 100% — or near-100% — renewable energy, at different locations around the world.
One study in the collection looked at global warming, air pollution and energy insecurity, creating Green New Deal roadmaps for 143 countries to overcome these problems.
The roadmaps call for these countries, which are collectively responsible for 99.7% of global CO2 emissions, to switch to 100% clean, renewable wind, water and solar power no later than 2050, with at least 80% renewables by 2030.
The study divides all the planet’s countries into 24 regions which can work together on grid stability and energy storage solutions, so energy demand matches supply between 2050 to 2052. After that, it’s possible to power the planet entirely by sustainable energy.
Switching to wind, water and solar worldwide could eliminate 4 to 7 million deaths from air pollution annually, while first slowing and then reversing the effects of global warming and, in doing so, stabilizing the global energy sector.
