11 Factors Inhibiting Pace and Volume of Renewable Energy Market Entrance Capital mobilization Lack of consistent, stable policies Electricity pricing: valuing externalities Further technology advances

12 Mobilizing Capital: Creative Business Partnership Models Catalyze entrepreneurs Enhance strategic partnering Attract new corporate entrants Invigorate private equity/venture capital

13 State Policies are Opening Markets for Renewable Energy

14 Renewable Electricity Standards Nevada: 15% by 2013, solar 5% of annual California: 20% by 2017 Arizona: 1.1% by 2007, 60% solar Minnesota: 19% by 2015* Iowa: 2% by 1999 Wisconsin: 2.2% by 2011 New Mexico: 10% by 2011 Texas: 2.7% by 2009 New York: 24% by 2013 Maine:30% by 2000 MA: 4% by 2009 RI: 16% by 2019 CT: 10% by 2010 NJ: 6.5% by 2008 Maryland: 7.5% by 2019 Washington D.C: 11% by 2022 Pennsylvania: 8% by States + D.C. Colorado: 10% by 2015 Hawaii: 20% by 2020 *Includes requirements adopted in 1994 and 2003 for one utility, Xcel Energy.

15 Western Governors Association Clean and Diversified Energy Initiative Western U.S is rich with fossil, hydro and renewable energy resources. Goal of 30,000 MW of clean energy by 2015, using solar, wind, geothermal, biomass, clean coal technologies and advanced natural gas technologies. Goal to increase the efficiency of energy use by 20% by Meet the West s generation and transmission needs over the next 25 years.

16 Create an Electricity Pricing Structure that Values Externalities Intangibles have value Greater value if dealt with in resource planning Allow a broader perspective Hard to quantify Has been controversial No accepted methodology

17 The Future for Renewable Energy: A Technology Outlook Wind Solar Biomass
