Meeting Energy Demand And Stopping Global Warming is both possible.Sustainable energy and technology can curb climate change and meet projected growth in demand for energy but only if key decisions are made within the next five years, according to a new WWF report. Climate Solutions: WWF’s vision for 2050 concludes that sustainable technologies can meet global projected energy demand while avoiding the most dangerous impacts of climate change. But it warns that the governmental policies needed to propel this transition are not now in place, or even in prospect in most cases.
