It's no surprise that we Americans are energy hogs. But everyday there are new developments that help us reduce our energy consumption. Soon auto shoppers will actually be able to believe the gas mileage stickers found on cars in dealer lots! The feds used to put fake numbers on the stickers because the test used to calculate mileage efficiency was bogus. So you could purchase a vehicle expecting to get something like 26 miles/gallon (city) or 38 miles/gallon (highway) and get substantially lower real mileage. Now the government is enforcing a legitimate mileage test, so all cars shipped to dealers after Sept. 1 will have real numbers posted on them. Why the sudden change? The Toyota Prius really pushed this along. People were expecting to get 50-60 miles/gallon but the actual numbers were so much lower that people really ripped off and complained.

Another positive change that's a little further off involves LED (light emitting diode) lighting. Clark and his wife often battle over using regular or CFL (compact fluorescent lamp) bulbs in their home. He has a number of CFLs from the '90s when the technology still had a lot of kinks. In fact, once he was doing a TV story about energy-smart homes and he wanted to demonstrate his lighting for the camera crew. The CFLs took about 70 seconds to come on after he flipped the switch! Today's CFLs are much better (and faster to light up), so his wife is now more open to using them in their home. But CFLs may soon be a thing of the past when LEDs hit the market. LED are now used in new billboards and offer just about the best artificial light possible while eating up low energy. They don't release extra heat and they last for years. LEDs will probably be in offices, retail stores and industrial parks before they're available for home use. Clark thinks within four years LEDs should become a popular consumer product.
