New paper shows that renewables can supply 100% of all energy (not just electricity) Posted on 20 August 2015 by michael sweet A new paper: 100% clean and renewable wind, water, and sunlight (WWS) all-sector energy roadmaps for the 50 United States by Jacobson et al 2015 describes the wind, solar and other renewable technologies needed to supply all the energy used in the USA That is all the energy, not just the electricity. They find that using wind to generate 50% of energy, solar photovoltaic (PV) for 38%, concentrated solar power (CSP) for 13% and a combination of hydro, geothermal, tide and wave power for the remainder (5%) allows all energy in the USA to be supplied at a lower cost than using fossil fuels. (The total is over 100% as extra power is required to stabilize the power grid because the wind does not always blow and the sun does not always shine).
