Answer: Switching to renewable energy could prevent 4 to 7 million deaths from air pollution annually worldwide.
Explanation: . It's possible to switch to a fully sustainable global energy landscape within the next 30 years, according to research.
. Greater geographical connectivity of solar, wind, and hydro power, can reduce energy use and cut costs.
. Without the support of policymakers, businesses and other organizations, the transition may not happen quickly enough to stay under the 1.5 degrees Paris warming target.
Renewable 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 theses 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 form air pollution annually, while first slowing and then reversing the effects of global warming and in doing so, stabilizing the global energy sector.
Hope this helps! :) If not, I am sorry. :( If it does help, then Your Welcome! :)
