Renewable Energy Integration The Only Real Sensible Approach must be done a resource optimized regional level
Overall Focus • Current and future sources of energy • What’s best in terms of most efficient combination of capital cost, land use, ecological footprint, material use. • Distributed Generation • How to improve the Grid • Local Energy Storage

And if we require continued Fossil Fuel usage as transport fuel then • Alternatives to Crude Oil must be used • These alternatives will do incredible environmental damage due to the great inefficiency involved in extracting a barrel of oil. • And of course, Coal remains the choice for producing the bulk of electricity

Centralized vs. Distributed Generation http://www.nfcrc.uci.edu/fcresources/FCexplained/stationary.htm
Central Power Generation (today) • Remote, Large, Expensive • Long Distance Delivery • Fossil Fuel Plants • Waste Heat (Nuclear) • Environment Unfriendly (Co2) • Health Unfriendly (Nox, So2, Pm10, Hg) • Nuclear Plants • Waste Disposal • Hydroelectric Plants • Flooding • Unreliable (2000-2003) • 110 Grid Failures • Cost $80-123 B./Yr • Adds 29-45% To Electric Bill http://www.pharmaciaretirees.com/distributed_generation.htm
Distributed Generation • Located next to user • Range of energy sources • Fossil fuel, waste gas, renewables, • Hydrogen, nuclear • Capacity kw –Mw • Economic benefits • “Waste” heat used • Lowers fossil fuel use • Low investment • Power failure losses eliminated • Environmental/ health costs reduced • Grid costs – peak/capital • Lower electric bills • Flexibility of location • Cogeneration • Combined heat & power (CHP) • Micropower http://www.pharmaciaretirees.com/distributed_generation.htm
Sources of DG • Solar – photovoltaic and thermal • Wind Turbines • Hydroelectric (large scale and micro) • Geothermal • Oceanic • Nuclear • Fossil Fuels • Combined Heat & Power (CHP) http://www.pharmaciaretirees.com/distributed_generation.htm
Microturbines • Low to moderate initial capital cost • Fuel flexibility, • burn either gaseous (natural gas, propane, biogases, oil-field flared gas) or liquid fuels (diesel, kerosene) • Heat released from burning the fuel also providing heating and cooling needs (CHP • Extremely low air emissions • NOx, CO, and SOx • Continuous operating even during brownout or blackout A cutaway of a microturbine; 30 and 60-kilowatt units have just one moving part – a shaft that turns at 96,000 rpm.

Summary • Solutions Exist both on small scale and very large scale • We do not really have an energy crisis – we do have an energy by fossil fuel crisis • Transition requires leadership and courage and commitment – a true test of humanity as a global entity. • OTEC, Wind, Small Scale Solar, Snakes, Dragons, Hydrogen Production represents solution space
