DENVER — Cheers fit for a revival meeting swept a hotel ballroom as 1,800 entrepreneurs and experts watched a PowerPoint presentation of the most promising technologies for limiting global warming: solar power, wind, ethanol and other farmed fuels, energy-efficient buildings and fuel-sipping cars.
“Houston,” Charles F. Kutscher, chairman of the Solar 2006 conference, concluded in a twist on the line from Apollo 13, “we have a solution.”
Hold the applause. For all the enthusiasm about alternatives to coal and oil, the challenge of limiting emissions of carbon dioxide, which traps heat, will be immense in a world likely to add 2.5 billion people by midcentury, a host of other experts say. Moreover, most of those people will live in countries like China and India, which are just beginning to enjoy an electrified, air-conditioned mobile society.
The challenge is all the more daunting because research into energy technologies by both government and industry has not been rising, but rather falling.
In the United States, annual federal spending for all energy research and development — not just the research aimed at climate-friendly technologies — is less than half what it was a quarter-century ago. It has sunk to $3 billion a year in the current budget from an inflation-adjusted peak of $7.7 billion in 1979, according to several different studies.
