    1. The Macro View of Wind Power Potential in the United States Mark Z. Jacobson Atmosphere/Energy Program Dept. of Civil & Environmental Engineering Stanford University From Local to Global: The Rhode Island Model for Harnessing Wind Power Worldwide University of Rhode Island, April 19, 2007

    3. Global Power Demand and Clean Renewable Supply

    4. Installed Wind Capacity Worldwide

    5. 2006 New U.S. Installations

    6. Mean 80-m Wind Speed in Europe

    7. Mean 80-m Wind Speed in North America

    8. Wind Statistics

    9. Percent of Land+Near Shore Stations With Annual Wind Speeds > 6.9 m/s at 80 m

    10. Global Day vs. Night Wind Speed Profiles Over Land From Soundings

    12. Wind Power v. Number of Farms

    13. Reducing transmission capacity 20% reduces power 9.8% with 1 turbine but only 1.6% with 19 turbines

    14. Aggregate Wind Power (MW) From 81% of Spain’s Grid Versus Time of Day, Oct. 26, 2005

    15. Birds and Wind

    16. Summary Sufficient wind and solar are available worldwide to supply all electric and nonelectric energy needs simultaneously several times over. One-third of wind can be smoothed to the same reliability as a typical coal-fired power plant by interconnecting wind farms. Additional wind can be smoothed with solar, hydro, geothermal. Remaining intermittent wind can be used for HFCVs and electric vehicles. Bird deaths from wind turbines are few compared with other sources of bird mortality and with reduction in bird, animal, human mortality due to displacing fossil fuels. Below 120 m, daytime winds are faster than nighttime winds in the global average; above 120 m, nighttime winds are faster.
