Agency Calls for ‘Energy Revolution’ – NYTimes.com

BRUSSELS — The International Energy Agency, a group that advises industrialized countries, said Friday in a report that investments of at least $45 trillion might be needed over the next half-century to prevent energy shortages and greenhouse gas emissions from slowing economic growth.

Nobuo Tanaka, the agency’s executive director, called for “immediate policy action and technological transition on an unprecedented scale.”

Mr. Tanaka said the world would “essentially require a new global energy revolution which would completely transform the way we produce and use energy.”

The report sends a strong warning that the combination of growing demand for energy in countries like China and India, the dangers of climate change and the scarcity of resources are going to require huge shifts in the global economy. Countries will have to overcome objections to building nuclear power plants and to storing large amounts of carbon dioxide underground or beneath the ocean floor.

The report also described emissions-cutting pathways that broadly match the advice of some leading scientists who have recommended cutting emissions in half by 2050 as a way of avoiding devastating climate change. Environment ministers from the Group of 8 industrialized countries have backed a 50 percent target. The ministers said governments should endorse that target at a G-8 summit in July.
