Solar and wind potential is far higher than that of fossil fuels and can meet global energy demand many times over, unlocking huge benefits for society. With current technology and in a subset of available locations we can capture at least 6,700 PWh p.a. from solar and wind, which is more than 100 times global energy demand. Opportunities unlocked The collapse in renewable costs in the last three years means that half of this solar and wind technical potential now has economic potential, and by the end of the decade it will be over 90%. The land required for solar panels alone to provide all global energy is 450,000 km2, 0.3% of the global land area of 149 million km2. This differs by country as highlighted below. Humans specialise in extracting cheap energy, and fast, as witnessed by the rapid development of shale gas. Now the opportunity has been unlocked, expect continued exponential growth of solar and wind deployment. The technical and economic barriers have been crossed and the only impediment to change is political. Sector by sector and country by country the fossil fuel incumbency is being swamped by the rapidly rising tide of new energy technologies. Even […]
