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.
Saudi Arabia can transition to a 100% renewable energy system by 2040, according to another Finnish study. While the country is known for its oil deposits, it is also rich in another energy source: sunshine to power solar energy.
By 2050, solar power could account for 79% of the country's energy demand, supported by enhanced battery and water storage solutions to lower energy system costs.
This study emphasizes the central role that energy storage will play in the transition to a sustainable energy landscape, to overcome the intermittent nature of solar and wind resources and provide power when there is no wind or sunshine.
