  • Arizona\'s Renewable Energy Resources

    1. 1. Arizona’s Renewable Energy Options A Summary of Current Technologies and Generation Potential Prepared by: Todd Landfried, Government Relations & Marketing Director
    2. 2. Concentrated Solar Power <ul><li>Solar Thermal Dish </li></ul><ul><li>A self-contained solar power system utilizing mirrors to automatically track the sun and focus solar heat onto a power conversion unit (PCU). This in turn converts the intense heat to grid-quality electricity. </li></ul><ul><li>These are utility-scale systems. </li></ul>
    3. 3. Concentrated Solar Power <ul><li>Solar Thermal Array </li></ul><ul><li>Uses flat mirrors called Heliostats to focus sunlight on a single point on a tower to heat water or molten salt to create high temperature steam that turns a steam turbine to generate electricity. </li></ul><ul><li>These are utility-scale systems. </li></ul>
    4. 4. Concentrated Solar Power <ul><li>Solar Trough </li></ul><ul><li>Uses a parabolic mirror to focus sunlight to heat a tube filled with oil. This oil is then used to vaporize a secondary fluid which is used to spin a turbine/generator that produces electricity. </li></ul><ul><li>These are utility-scale systems. </li></ul>
    5. 5. Solar Tower <ul><li>Uses a greenhouse to heat air at ground level that is then channeled into a large tower containing wind generators at the base. </li></ul><ul><li>Simple convection draws the warm air up through the tower, turning the turbines that generate electricity. Heat can be stored to extend power generation periods. </li></ul><ul><li>This is a utility-scale system. </li></ul>
    6. 6. Solar Photovoltaic (PV) <ul><li>Uses specially designed silicon (or other like materials) to convert sunlight to DC electricity. Can be mounted on the ground or on rooftops. </li></ul><ul><li>Dramatic improvement in efficiency through introduction of new manufacturing methods and technologies. </li></ul><ul><li>These are residential, commercial or utility-scale systems. </li></ul>

    8. 8. Hydroelectric Dam <ul><li>The basis of hydroelectric power generation is that water at height has certain potential energy. The height is referred to as the head. Water is released through an intake at the base of the dam and the pressure turns a turbine that produces electricity. </li></ul><ul><li>These are utility-scale systems. </li></ul>
    9. 9. Pumped Storage Hydroelectric <ul><li>Pumped storage facilities consist of both high-elevation and low-elevation reservoirs. The pumped storage uses electricity during low demand times to pump water from the low-elevation reservoir to the high-elevation reservoir. Then during peak power demands the water is allowed to flow back down, turning a turbine like that used in a dam. </li></ul>
    10. 10. Biogas Power <ul><li>Takes animal waste, primarily from dairy cows and food processors, and use the natural decomposition process to create natural gas. The renewable natural gas is used by utilities and other power providers to produce electricity or inject into commercial gas lines. </li></ul><ul><li>These are small-to medium size systems. </li></ul>
    11. 11. Landfill Gas (LFG) <ul><li>Landfill gas is produced by the decomposition of the organic portion of waste stored in landfills. Considered one of the more mature and successful waste-to-energy technologies, LFG can be used to generate electricity, process heat or can be further refined for pipeline sales. </li></ul><ul><li>These are small-to medium size systems. </li></ul>

    13. 13. Geothermal Power <ul><li>Energy generated from heat stored in the earth, or the collection of absorbed heat derived from underground. </li></ul><ul><li>Closed-loop systems pass moderately hot geothermal water by a secondary fluid with a much lower boiling point than water. This causes the secondary fluid to flash to vapor, which then drives the turbines. The water is then pumped back into the Earth for reheating and reuse. </li></ul><ul><li>These are utility-scale systems. </li></ul>

    15. 15. Wind Power <ul><li>A wind turbine is a rotating machine which converts the kinetic energy in wind into mechanical energy, which is then used to generate electricity. </li></ul><ul><li>Current capacity of wind turbines is typically 1-3MW, although the capacity factor is expected only 20-40% of the time. </li></ul>
