  1. Energy Alternatives CDAE-06 Renewable Intro Gary Flomenhoft http://www.uvm.edu/~gflomenh/CDAE06/

  2. World Energy

  3. DIRECT-GAIN • Large south facing windows that let in the sunlight. • Thermal mass is used to absorb the radiation. • At night the absorbed heat is radiated back into the living space.

  4. CDAE 170 Solar Building Strategies PV system design Dec. 1, 2003 Gary Flomenhoft BSME, MAPP, CEE Research Associate Gund Institute, SNR

  5. Photoelectric Effect A picture of an typical silicon PV cell Now a short video: http://www.eere.energy.gov/solar/multimedia.html

  6. Biomass: In Vermont VT Energy Consumption Sources • Nuclear 36% • System 14% • Hydro Quebec 35% • Oil 2% • Gas 1% • Other Renewable 5% • Small Hydro 7% Since 1984, Vermont has met all increase in energy demands(a total of 125 Mw) by renewable in-state sources: -40 Mw Small Hydro -73 Mw McNeil/Rygate (Biomass Plants) -6 Mw Searsburg Wind Farm EPA Landfill Incentive Program http://www.epa.gov/lmop/

  7. Pros of the Project •Replaces 113 million tons of oil per year • “Zero-emissions” •Boost to Cape Cod’s economy -600-1,000 new jobs for Cape Codders •Does not require land •May help with navigation and rescue

  8. The Alliance’s Simulation from Cotuit

  9. Currently • 1/10 of electricity, US. • 20% World electricity

  10. Inside of Micro Turbine • 4 inch diameter impulse turbine • Creates 200 watts of power • Cost $1440

  11. How it works • First generation, barrage-style tidal power plants • Works by building Barrage to contain water after high tide, then water has to pass through a turbine to return to low tide • Sites in France (La Rance), Canada (Annapolis), and Russia • Future sites possibly on Severn River in England, San Francisco bay, Passamaquoddy

  12. Barrage not need, limiting total costs Two types- vertical axis and horizontal axis Davis Hydro turbine….. Successfully tested in St. Lawrence Seaway Harness the energy of tidal streams More efficient because they allow for energy production on both the ebbing and surging tides One site has potential to equal the generating power of 3 nuclear power plants Second-generation tidal power plants

  13. Wave Power

  14. Tectonic Plates • Plates are in constant motion (several centimeters/yr). • When collision or grinding occurs, it can create mountains, volcanoes, geysers and earthquakes. • Near the junctions of these plates are where heat travels rapidly from interior.
