“Using less energy to provide the same level of energy service”

Workers roll tarps over a glacier on the Zugspitze mountain to help prevent summer melting. We do need to wait for future temperature rises to see that we are in trouble. This picture calls for a crash program to cut down carbon emission.

"Supporting the development of the latest industrial technologies plays an important role in helping U.S. industry to lead the world in energy efficiency and productivity"

“Hybrid electric charging stations will soon connect to cars in the most convenient places. These areas will be located in parking spaces and sidewalks in an effort to reduce carbon emissions and to reduce our dependency for foreign oil”

Considering the above two ideas means moving towards Lester Brown’s Plan B and this is a good sign that at least we are trying to act now.

In his book Plan B 3.0, Brown says that wind , being the most abundant, low cost and widely distributed makes it the center piece of Plan B

Solar thermal collectors simply convert light into infrared energy (heat energy). Efficiency levels reach levels as high as 75%, which proves to be economically when utilized in commercial and residential solar hot water systems. Brown also says that with the cost of rooftop water and space heating systems declining, most countries will join in mandating that all new buildings incorporate rooftop water and space heaters.
