A new study from Stanford University has emerged out which says that the world can reach 100% renewable by 2050.

The study led by Stanford’s Atmosphere/Energy program made a new detailed analysis on energy road-maps of 139 countries. Basically, the road-map calculated the energy requirements of countries by 2050 for agriculture, transportation, electricity, heating, cooking and forestry purposes.

Atmosphere/Energy program director Mark Z. Jacobson who published the study, stressed upon “WWS”- Wind, Water and Sunlight. According to the study, WWS can fully meet the energy requirements of each country by 2050 and 80% by 2030.

“People who are trying to prevent this change would argue that it’s too expensive, or there’s just not enough power, or they try to say that it’s unreliable, that it will take too much land area or resources,” Jacobson said in an interview to the website Co.Exist

The study also provided the technologies to be used under a 100% WWS scenario.

With 100% WWS, ground transportation will be completely electrified with Battery electric vehicles and hydrogen fuel cell vehicles acting as a means of transportation. Electric heat pumps will serve the purpose of air heating and cooling.

The energy road-map lays out a profitable analysis with $5 trillion savings from an environment, climate damage and fuel cost.

Interestingly, Stanford has also published a separate research paper on 100% renewable possibility in the US by 2050. The study laid out a separate detailed plan for each of the 50 states to fully turn renewable by 2050 .
