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

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.

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
