Staggering cost of a wind and solar future in the Northwest

· Some academics claim that the U.S. can end reliance on fossil fuels by electrifying most everything - cars, trucks, space and water heat, etc. - and supply the needed electricity solely with wind, solar and hydroelectric energy, without increasing costs. But our study of the cost of doing so just for Oregon and Washington state shows this belief to be a fantasy. Both states

Renewable Power Generation Costs in 2022

In 2022, the global weighted average levelised cost of electricity (LCOE) from newly commissioned utility-scale solar photovoltaics (PV), onshore wind, concentrating solar power (CSP), bioenergy and geothermal energy all fell,

Here''s what it would take for the US to run on 100% renewable energy

No uniform definition for 100% renewable energy systems has been adopted across the published literature. Recent studies show that a global transition to 100% renewable energy across all sectors – power, heat, transport and desalination well before 2050 is feasible. According to a review of the 181 peer-reviewed papers on 100% renewable energy that were published until 2018, "[t]he great majorit
