Photovoltaics: meeting the environmental imperatives of clean air and climate change

Abstract

In order to stabilize atmospheric concentrations of carbon dioxide even at current elevated levels, computer models suggest the need to reduce emission rates by approximately 75%. An analysis of policy options shows that a combination of vastly improved energy efficiency strategies and carbon-free energy production technologies will be essential to even slowing the rate of global warming. Current knowledge of the greenhouse effect and its consequences area summarized, and how photovoltaic (PV) electricity can contribute toward atmospheric stabilization goals is examined. Some specific examples and strategies that may accelerate the rate at which PV technologies can penetrate the market are given.<>
