  1. IPED COAL POWER CONFERENCE Current Trends in Renewable Energy: Tangible and Intangible Benefits presented by January 18-19, 2007 St. Petersburg, FL David L. Patton, P.E. R. W. Beck, Inc.

  2. Which Renewable Candidates are Realistic Now? • Wind • Biomass • Fuel Cells • Geothermal • Hydro • Ocean (Tidal, OTEC) • Solar (PV, Thermal)

  3. Biomass (Total) Wood/Wood Waste MSW/Landfill Gas Geothermal Other Biomass Solar Wind Renewable Energy Capacity Trend,1999 - 2006 14,000 12,000 10,000 8000 Installed Capacity, MW 6000 4000 2000 0 2006 2000 2001 2002 2003 2004 2005 Year Source: U.S. DOE EIA, August 2005

  4. U.S. Renewable Electric Generating Capacity 2005 Coal 23% Nuclear Biomass 8% 46% Natural Gas 23% Renewables 6% Conventional Hydroelectric 46% Geothermal 5% Wind 2% Petroleum Fuels Solar 40% 1% Source: U.S. DOE EIA, January 2007

  5. Wind Energy – Tangible Benefits • No Fuel Price Uncertainty • No Fuel Cost • Low Operating Cost • Relatively Less Complex • Mature Wind Turbine Technologies • Addresses Environmental Issues • Lease Payments Support Family Farms • Government Financial Incentives & Grants

  7. U.S. Annual Wind GeneratingCapacity: Installed and Projected 3500 3250 3000 2750 2500 2250 2000 1750 MW Installed During Year 1500 1250 1000 750 500 250 0 2007 (projected) 1981 1983 1985 1987 1989 1991 1993 1995 1997 1999 2001 2003 2005 Source: U.S. DOE Wind Energy Program and AWEA

  8. Biomass Energy – Tangible Benefits • Lower Fuel Costs • Addresses Environmental Issues • Domestic Sources • Local Economic Benefits • Mature Biomass/Biogas Process Technologies • Government Financial Incentives & Grants

  9. Biomass Resource Availability Biomass Fuel for Generation is Widespread Within Most States MA, CT, RI, NJ, DE, MD, DC States with Renewable Portfolio Standards (RPS) / Goals Source: NREL and PEW Center, Global Climate Change

  10. States with Renewable Portfolio Standards (RPS) / Goals Source: NREL and PEW Center, Global Climate Change

  11. Intangible Benefits – All Renewables • Positive Public Image • Desire for Diversified Portfolio • Public Support/Perception • Political Support • Greenhouse Gas Drivers • Energy Independence / Security • Offset Emissions from “Dirtier” Energy Sources

  12. RPS Goals vs. Renewable Status * As a percent of state generation or actual generation / use. Source: U.S. DOE EIA & PEW Central Global Climate Change, December 2006

  13. Summary • Realistic Renewable Candidates • Renewable Energy Capacity Trends • Recent Renewable Capacity • Wind Energy – Tangible Benefits • Biomass Energy – Tangible Benefits • Intangible Benefits – All Renewables • RPS Goals

  14. Electricity Generation by Fuel, 1980-2030 (billion kilowatt hours) 4000 History Projections Coal 3000 2000 Natural Gas 1000 Nuclear Renewables Petroleum 0 1980 2020 2030 2005 1990 Source: U.S. DOE EIA

  15. Conclusions • Biomass and Wind are Currently the Most Commercially Realistic Renewables • 25,000 to 50,000 Megawatts New Renewable Energy Capacity Nationwide in Next Decade • Policy Consistency and Continuity
