"This WWF report seeks to answer the question: "Is it technically possible to meet the growing global demand for energy by using clean and sustainable energy sources and technologies that will protect theglobal climate?" In other words, can a concerted shift to the sustainable energy resources and technologies that are available today meet the more than doubling of global energy demand projected by 2050, while avoiding dangerous climatic change of more than two degrees Celsius above pre-industrial levels?
The report's conclusion is that the technologies and sustainable energy resources known or available today are sufficient to meet this challenge, and there is still sufficient time to build up and deploy them, but only if the necessary decisions are made in the next five years. Yet it is clear that the economic policies and governmental interventions needed to propel this transition are not now in place, or even in prospect in most cases. This is a matter to which the world needs to give urgent attention."
