  1. Renewables: Who’s Leading the Way?

  2. Units of Energy Consumption • Watt (W): basic unit of electrical power • kilowatt (kW): 1,000 watts • kilowatt-hours (kWh): unit used for expressing energy use per hour (useful for billing) • Megawatt (MW): 1,000,000 watts

  3. Electricity Consumption • 21.38 trillion kWh consumed globally • U.S. consumes 3.9 trillion kWh • China consumes 5.5 trillion kWh • European Union 2.8 trillion kWh • Japan 934 billion kWh • Russia 1 trillion kWh • India 973 billion kWh CIA World Factbook, 2014

  4. Electricity Consumption • What percentage of the world’s electricity is consumed by the United States? (18%) • What percentage is consumed by the top 6 electricity-using countries? (71%) CIA World Factbook, 2014

  5. The Energy Forecast: 2040 • Nonrenewable sources of fuel for electricity will still dominate the market, with 70-75% of the world’s consumers still relying on fossil fuels and nuclear power Source: DOE/EIA-0484(2015)

  6. Nonrenewable Energy Sources • Will not be replenished naturally • A finite amount exists—once it’s gone there is no more • Fossil fuels [petroleum, coal, natural gas] • Radioactive ore • Their use has environmental and economic consequences

  7. The Energy Forecast: 2040 • An estimated 20-25% of the world’s electricity will come from alternative, renewable sources of power • 33% of the electricity in the U.S. will come from renewable sources Source: DOE/EIA-0484(2016); US EIA Energy in Brief

  8. Renewable Energy Sources • Regenerate naturally in a relatively short amount of time • Biomass—from plant material and organic waste • Geothermal—from the earth’s heat • Solar—from the radiant energy of the sun • Hydro—from falling water or ocean tides • Wind • Their use also has environmental andeconomic consequences

  9. How Much of Our Electricity Comes from Renewable Sources? http://wnew.www.eia.gov/energyexplained/index.cfm?page=renewable_home

  10. Who’s Leading the Way in Biomass Power Production? • 75 garbage-to-electricity plants in the U.S. • 601 landfills have 654 operating gas-to-energy projects in the U.S. • California has 106 landfill gas energy projects; Michigan has 77, and Illinois has 45 • Biomass use is underreported globally, as itcan include burning wood or trash for heating and cooking Source: EIA, Energy Kids

  11. Where’s the Geothermal Activity? Source: U.S. Department of Energy, Energy Efficiency & Renewable Energy

  12. Who’s Leading the Way in Geothermal Use? • California—The Geysers is the world’s largest plant generating electricity from steam produced from geothermal power (725MW) • Philippines (1870 MW) • Indonesia (1340 MW) • Mexico (1017 MW) • Italy (916 MW) • New Zealand (1005 MW) • Iceland (665 MW) Source: eia.gov, wikipedia (2016)

  13. What Do These Geothermal Regions Have in Common? • They are near fault lines (earthquake zones, volcanoes, etc.) = geologically active

  14. Who’s Leading the Way in Solar Power Production? • California: Solar Energy Generating Systems consists of 9 concentrating solar plants in the Mojave Desert; largest thermal solar plant in the world • Portugal and Germany have large photovoltaic installations • China is now the largest manufacturer of solar panels • Covering just 4% of the world’s deserts withPV cells would provide electricity for the whole world Source: EIA Energy Kids; NYT, “China Leading Global Race to Make Clean Energy

  15. Who’s Leading the Way in Hydro?

  16. Who’s Leading the Way in Hydropower Production Globally? • China (549 billion kWh) • Brazil (387 billion kWh) • Canada (363 billion kWh) • United States (272 billion kWh) • Russia (162 billion kWh) • Norway (125 billion kWh) Source: EIA, International Energy Statistics, 2009

  17. Who’s Leading the Way in Wind?

  18. Who’s Leading the Way in Wind Power Production Globally? • United States (190 billion kWh) • China (186 billion kWh) • Germany (88 billion kWh) • Spain (48 billion kWh) • United Kingdom (40 billion kWh) • China is now the world’s largest maker of wind turbines Source: https://www.ieawind.org/annual_reports_PDF/2015.html
