Summary
A large-scale wind, water, and solar energy system can reliably supply all of the world’s energy
needs, with significant benefit to climate, air quality, water quality, ecological systems, and
energy security, at reasonable cost. To accomplish this, we need about 4 million 5 MW wind
turbines, 90,000 300-MW solar PV plus CSP power plants, 1.9 billion 3 kW solar PV rooftop
systems, and lesser amounts of geothermal, tidal, wave, and hydroelectric plants and devices.
The obstacles to realizing this are primarily social and political, not technological. As discussed
above, a combination of feed-in tariffs and an intelligently expanded and re-organized
transmission system may be necessary but not sufficient to enough ensure rapid deployment of
WWS technologies. With sensible broad-based policies and social changes, it may be possible to
convert 25% of the current energy system to WWS in 10-15 years and 85% in 20-30 years.
Absent that clear direction, the conversion will take longer, potentially 40-50 years.
90000 centrales solaires de 300 MW. Voila un peu de travail pour Remundo.
