We're saved!: By 2015 or 2020, maybe solar photovoltaic energy will have produced more energy than it's consumed!

Toward Perpetuity: Global Solar Is Skyrocketing, Will Soon Be Net Positive Energy Source | ThinkProgress

Solar photovoltaic production consumed more energy than it produced while it was getting started. The whole industrial process has taken more energy to create than solar PV has produced — and created more greenhouse gases than it prevented — since 2000. However, a study from Stanford University found that in recent years, all the electricity produced by solar panels in the world has become greater than the energy required to produce it. Due to the amazing growth of the industry, it will generate enough energy by 2015 or 2020 to have “paid back” the energy debt accumulated while the industry got on its feet.
