"Researchers at the Lappeenranta-Lahti University of Technology (LUT) in Finland and Energy Watch Group (EWG) have completed a 4½ year study that examined how to meet the goals of the Paris climate accords without such measures as carbon capture and geoengineering. Their conclusion? Run everything on electricity and generate all of that electricity using renewables, primarily solar.
When the scientists say electrify everything, they mean that quite literally — all transportation, all building heating, all manufacturing, and all desalinization. A fantastical, theoretical goal? Not at all, the study says. “A global transition to 100% renewable energy across all sectors — power, heat, transport, and desalination before 2050 — is feasible.” In fact, the authors say it could be done quicker than that, according to RenewEconomy.
“Existing renewable energy potential and technologies, including storage, is capable of generating a secure energy supply at every hour throughout the year. The sustainable energy system is more efficient and cost-effective than the existing system, which is based primarily on fossil fuels and nuclear. A global renewable transition is the only sustainable option for the energy sector, and is compatible with the internationally adopted Paris Agreement.”"
