Electricity in a Sustainable Future Downside: Population growth Enhancement of economic well-being Ignoring true life-cycle costs Upside: Decreases in energy intensity per capita and GDP New technologies for efficient use of energy Public awareness California can lead the way in making a difference!
Power Generation Trends (IEA) • World electricity demand increases by 2.7% p.a. • Coal remains N0. 1 source for power generation • Coal’s share declines in OECD area, but triples in developing countries • Natural gas grows 350% by 2020 • Shares of hydro, nuclear and oil decline • Renewables will increase rapidly, but remain at a low level

PowerLight’s PowerGuard PowerLight’s insulated 30 year roof system reduces building air conditioning loads while it’s PV surface generates electricity during hot and expensive peak summer hours While California is known for its hot dry summers, that same solar resource provides a clean, safe and reliable way to generate electricity
The Wind Turbine Company • Design, develop and demonstrate a utility-scale wind turbine • Horizontal axis, two-blade, downwind design • Prototype developed for PIER and tested at NREL rated at 250 kW • Commercial prototype demonstration sited at the Fairmont Reservoir in LADWP territory for a 500 kW - scaled up to 750 kW - wind turbine demonstration to begin in October 2001 • Goal is to produce electricity $0.035 cents per kWh per 100 unit wind farms with wind resources 15 mph.
Fuel Cell / Turbine Hybrids • Integration of a fuel cell and a gas turbine into a single unit • Efficiency: 70% • Cost: 20-25% lower than non-hybrid fuel cell • Year: 2010
