The world could be 100% renewable by 2050
A new study by Stanford University’s Atmosphere/Energy Program makes the case that the world could be fully powered by renewable energy as early as 2050 by detailing the necessary resources for each country.
Researchers analyzed energy roadmaps for 139 countries and calculated how much energy they would need to meet demand for:
- household electricity
They examined the best renewable energy sources for the different countries and which ones made the most economic sense for each nation.
According to their findings, solar, wind and hydro power could cover most of the energy demand in each country.
Geothermal energy would also benefit a number of countries
100% renewables by 2025
Presenting a timeline for full adoption of renewables, the study says countries would stop building new coal, natural gas, biomass or nuclear plants by 2020
- new home appliances like stoves and heaters would be electric, not gas
- By 2025, new cargo ships, trains, and buses would be electrified
- followed by cars and trucks by 2030
- by 2050, the transition would be complete with less than 10% greenhouse gas emissions comparing to 1990
Benefits green power
Green, renewable energy will reduce risks and has a lot of benefits:
- Adoption of a global green energy infrastructure would provide power to 4 billion! people
- The energy independence of countries would eliminate a major cause of global conflict
- Decentralizing power would reduce the danger posed by terrorism and lower the risk of outages by storm
- As for the added benefits to health and climate, the study estimates that widespread use renewables would save 4 to 7 million lives a year of people who would have died from air pollution
- Green energy sources would lead to a stabilization of energy prices, since renewables are not dependent on a commodity fuel
- and would create some 20 million more jobs than those lost in the fossil fuel sector
- Climate greatest risk to world’s economy
- COP21 – 1.5 degrees? Only with CO2 storage and fossil-free by 2030
