Rapid energy transformation at the national level is possible. Transformation is also necessary if we are to mitigate the impacts of climate change and peak oil. The kind of transformation we need in the U.S. has been demonstrated vividly by an increasing number of nations shifting rapidly to a renewable energy economy. Spain and Portugal are currently the most powerful examples of this transformation.
Spain has grown from using just two percent wind and solar power to almost 20 percent in a decade. Figure 1 demonstrates this growth at the same time as Spain’s electricity consumption grew rapidly – by 50 percent – from 2000 to 2008, only to drop equally rapidly from recession and price-induced conservation since 2008.
Spain now enjoys about 35 percent total renewables, when we include large hydroelectric, with the rest of its power coming from natural gas, coal and nuclear. Moreover, Spain is a good comparison to California because its population and climate are very similar to ours.
