  1. Solar Energy Global Energy Production Solar Energy – How to capture it? Storage Cost Prospects

  2. Worldwide Energy Sources (1)

  3. Photovoltaics or Concentrated?

  4. Two Main Issues Storage (Dealing with Intermittency) Relative Cost

  5. Thermal Energy Storage Approximately 93% efficient

  6. Battery Banks • Approximately 90 % efficient • Common uses Lead Acid batteries

  7. Pumped-storage Hydroelectricity • Approximately 75% efficient

  8. Prospects • Background shows solar ‘hotspots.’ • Study by IAE (International Energy Agency) asserts that Solar Energy will be main source of global energy within 50 years. Optimistic? • >50% of cost is Photovoltaic cell

  9. Prospects cont’d • Economies of scale • Small scale vs. large scale • ~8000:1
