PRESIDENT Obama has laid out an ambitious agenda for dealing with our energy needs and climate change: he proposes to double the supply of renewable energy within three years, establish a cap-and-trade program to reduce carbon emissions and use federal stimulus dollars to help homes, businesses and governments use energy more efficiently. This is the right blueprint for increasing the number of green jobs, encouraging economic growth, ensuring that the United States has the energy it needs at reasonable prices, and reducing the risk of global climate change.

But as Congress translates this grand plan into legislation, lawmakers should resist calls to add an extensive and costly new transmission system that would carry electricity from remote areas like Texas, the Great Plains and Eastern Canada to places with high energy demands like Boston, Chicago and New York. This idea is being promoted by energy companies and by elected officials who see it as an economic development opportunity for their particular state or region. Long-distance transmission lines are needed, they argue, to ensure that the president’s energy goals are met.

But there are better  and cheaper  ways to get more clean power flowing to the big cities.

Renewable energy resources are found all across the country; they don’t need to be harnessed from just one place. In the Northwest, the largest amount of green power comes from hydroelectricity. In the Northeast, the best source may be the wind over the ocean, because it blows harder and more consistently there than on land. Offshore wind farms have been proposed for Delaware, Massachusetts, New Jersey and Rhode Island. In the Southwest, solar energy can be tapped on a large scale. And in the Southeast, biomass from forests may one day be a major source of sustainable power. In each area, developing these power sources would be cheaper than piping in clean energy from thousands of miles away.

Unlike our federal highway system, which is needed to transport goods across the country, or the “information superhighway” of the Internet, which is the fastest way to carry information around the world, long-distance transmission lines have no inherent value. On the contrary, the farther electricity is transported, the more of it is dissipated. “Line loss,” as this is called, gobbles up an estimated 2 percent to 3 percent of electricity nationally.
