  1. 1. Current Options, Future Problems: New York City’s Current Fuel Options, the Energy Situation, and Their Effects on the Ecological Footprint Presented by: Yoni Jacobs HNRS 226
  2. 2. Abstract <ul><li>Current energy decisions are not the best </li></ul><ul><li>New York and U.S. too dependent on oil </li></ul><ul><li>Fossil fuels have damaging effects </li></ul><ul><li>Can coal be used? </li></ul><ul><li>Should we switch to other energy sources? </li></ul><ul><ul><li>Nuclear </li></ul></ul><ul><ul><li>Wind </li></ul></ul><ul><ul><li>Solar </li></ul></ul>
