  2. Learning Outcomes • An understanding of energy efficiency • Simple suggestions to save your wallet and the environment • Why an energy audit makes sense • The NELC and its purpose • Signing up for an audit and expectations

  3. Electric Bills in the United States eia.gov

  4. What could you spend the savings on? • Let’s estimate 25% savings using 2012 numbers: • $107.28 * 0.25 = $26.82/month • $26.82 * 12 months = $321.84/year 1288 gumballs!!!

  5. Where do we use energy in our homes?

  6. What is energy efficiency? • Energy efficiency is the ratio between the useful output of an energy conversion machine and the input, in energy terms. The useful output may be electric power, mechanical work, or heat. • Our definition? Using less energy to provide the same service. • Fact: 100 million homes, or 80% of US houses, are built with no regard to energy efficiency!
