2. Toyota Prius
The first mass-produced hybrid vehicle. First sold in Japan in 1997 and the U.S. in 2001.
Hybrid Synergy Drive gas/electric engine
Averages 46 miles per gallon, making it the most fuel-efficient vehicle sold in the U.S.
Classified as a Super Ultra Low Emissions Vehicle (SULEV). Produces less than 10% of the air pollution of a comparable all-gas vehicle.
Electric motor is powered by a 200-volt nickel-metal hydride (NiMH) battery that stores over 1300 watt-hours of energy

3. Green Features
Regenerative braking uses a generator to recapture energy that would normally be lost as heat during braking.
This is used to recharge the battery when slowing to a stop or going downhill.
Electric engine is used alone at low speeds to reduce gas consumption.
The highly efficient gas engine is optimized to run at a high RPM, since the electric engine is used a lower speeds.
Warm coolant is automatically stored in an insulated container when the car is not in use and pumped back in when the car is restarted. This saves gas by reducing engine warm-up time.
The unused space in the gas tank is filled by a bladder that expands as the gas is consumed. This reduces gas lost to evaporation.

4. Energy Efficient Appliances
Compact Fluorescent Light bulb
These light bulbs are becoming increasingly popular as a highly efficient alternative to standard incandescent bulbs.
A single 20-watt CFL will provide the same amount of light as a 75-watt incandescent light bulb and last up to seven times longer.
CFLs use less energy and last longer
Laundry
Optimal Size Load
Use Lower Temperature settings
Use energy saving features
Reduce drying time
