  2. 2. Solar Power <ul><li>Photovoltaic or </li></ul><ul><li>Photoelectric cells </li></ul>University of Manchester CIS Tower, Manchester Courtesy: solarcentury
  3. 3. Wind power <ul><li>A typical turbine (1.8MW) generates: </li></ul><ul><li>4.7 million units of electricity each year </li></ul><ul><li>Power 750 homes </li></ul><ul><li>Make 170 million cups of tea </li></ul><ul><li>Run 1,620 computers for a year </li></ul><ul><li>Saves emissions of 1,333 cars </li></ul>Courtesy: Scottish Power 25,022 tonnes 83,405 tonnes 7,172,850 tonnes 1,774,579 3173 2388 197 NO X reductions (pa) SO 2 reductions (pa) CO 2 reductions (pa) Homes Equiv.

  5. 5. Fuel cells: hydrogen to replace oil? <ul><li>Proton exchange membrane splits hydrogen into hydrogen ion and electron </li></ul><ul><li>Electron moves around the circuit </li></ul><ul><li>Proton, electron and oxygen recombine to form ‘waste’ water </li></ul><ul><li>Hydrogen may be produced by the electrolysis of water, using electricity from photovoltaics </li></ul>Honda Puyo concept vehicle powered by a fuel cell.
  6. 6. Biofuels <ul><li>Bioethanol – mixed with petrol (5-10%) or used in modified engines (85%) </li></ul><ul><ul><li>fermentation of sugars and starch (food crops) </li></ul></ul><ul><ul><li>developing systems using cellulose and lignin (non-food part of plant) </li></ul></ul><ul><li>Biodiesel – diesel from crude oil mixed with vegetable oils (up to 30%) </li></ul>
  7. 7. Gas to liquid <ul><li>Large reserves of natural gas (methane) but difficult to transport </li></ul><ul><li>Convert methane into larger molecules that can be blended into diesel fuel </li></ul><ul><li>Transport and use becomes easier to allow greater exploitation of gas reserves </li></ul><ul><li>Gives ‘cleaner’ diesel </li></ul>
