Sometimes the most logical, most obvious solutions are the most difficult to see.

While the presidential campaign was mired in the egregious and the trivial last week, there was a hearing in Washington that addressed what should be a critical component of the nation’s energy strategy. It got very little attention.

Put aside for a moment all the talk about alternative fuels. They are no doubt important and the wave of the future. But the fastest, cheapest, easiest and cleanest step toward a sane energy environment  a step available to all of us immediately  is the powerful combination of efficiency and conservation.

That was the message delivered again and again at a hearing of the Joint Economic Committee that carried the title, “Efficiency: The Hidden Secret to Solving Our Energy Crisis.”

Two political leaders who are no longer very fashionable were on to this long ago  former Gov. Jerry Brown of California (derided as “Governor Moonbeam”) and former President Jimmy Carter, who presciently said of the energy crisis in 1977: “With the exception of preventing war, this is the greatest challenge our country will face during our lifetime.”
