Within a few decades...the United States might get 30% of its electricity from sunshine.
Christopher FlavinThe real potential of electricity lies not in providing social amenities but in stimulating long-term economic development
Christopher FlavinThe 1,230 gigawatts (GW) of renewable power generating capacity in place at the end of 2009 now constitutes just over 25 percent of total generating capacity worldwide. This is over three times nuclear generating capacity and roughly 38 percent of the capacity of fossil fuel-burning power plants worldwide.
Christopher FlavinThe sunlight ... that strikes Earthโs land surface in two hours is equivalent to total human energy use in a year. While much of that sunlight becomes heat, solar energy is also responsible for the energy embodied in wind, hydro, wave, and biomass, each with the potential to be harnessed for human use. Only a small portion of that enormous daily, renewable flux of energy will ever be needed by humanity.
Christopher FlavinRenewable biofuels are meanwhile making inroads in the transportation fuels market and are beginning to have a measurable impact on demand for petroleum fuels, contributing to a decline in oil consumption in the United States in particular starting in 2006... The 93 billion liters of biofuels produced worldwide in 2009 displaced the equivalent of an estimated 68 billion liters of gasoline, equal to about 5 percent of world gasoline production.
Christopher FlavinThe challenge now is to renovate the baroque structure that the Kyoto Plan has becomeโor else scrap it and get ready to start all over.
Christopher FlavinImproved energy productivity and renewable energy are both available in abundanceโand new policies and technologies are rapidly making them more economically competitive with fossil fuels. In combination, these energy options represent the most robust alternative to the current energy system, capable of providing the diverse array of energy services that a modern economy requires. Given the urgency of the climate problem, that is indeed convenient.
