  1. Energy Conservation By Shannon Beauregard, Chris Bruno, and Dan Gutter

  2. Easy Ways to Conserve Fluorescent Light bulbs Better insulation in the house Reducing air infiltration by sealing cracks, loose joints Caulk around doors, windows, foundation joints, electrical outlets Turn off appliances

  3. New Ideas for Conservation All new washing machines will use 35% less water Air conditioners will be required to be 20% more efficient New houses will be built with super insulated walls Special double-glazed windows and walls Internal reflective coatings Sod Roofs Houses shaded by trees or roof overhangs Straw-bale construction-high insulating qualities and inexpensive material

  4. Housing Examples

  5. Transportation Stats Cars and trucks account for 40% of U.S. oil consumption and create 1/5 of Carbon Dioxide emissions Raising the average fuel efficiency of each car by 3 mpg would save U.S. 25 Billion dollars a year There are more vehicles in the U.S. then licensed drivers Averaging 1 billion trips per day

  6. Transportation Efficiency Hybrid Gasoline-Electric Vehicles: Highest efficiency rating and lowest emissions in the U.S. Diesel vehicles are also more efficient Hydrogen fuel-cell powered vehicles: produce water as their waste product (these are too expensive right now!) Most hydrogen is currently created with natural gas

  7. Net Energy Yield Based on the total useful energy produced during the lifetime of an entire energy system minus the energy required to make useful energy available(ratio) Example: Nuclear Power-large amount of electricity from a small amount of fuel This is good for comparing the efficiency of different energy sources

  8. Negawatt Programs Instead of producing new plants, we’re finding it is less expensive for energy companies to conserve energy Conservation costs about $350 per KW while a new Nuclear Plant costs between $3000-$8000 per KW of installed capacity

  9. Cogeneration The simultaneous production of energy (electricity) and heat This increases the net yield of energy from 30-35% to 80-90% In the 1900’s this was popular, but eventually power plants moved away from communities and long transmission lines were used, making cogeneration unpopular-more expensive Starting to make a comeback! It saves money, is cleaner, and efficient
