“Near-Zero Energy Homes” help with demand reduction during the peaks ZEH4, a 1,200 ft2 Habitat for Humanity house in the research park in Harmony Heights, Lenoir City, Tennessee Ambient temperatures compared with temperatures in ZEH5 on August 16, 2007, the day that TVA met its all-time high demand for electrical power. Demand for electricity was lowest at the hottest part of the day on August 16, 2007. Presentation_name

Hydropower- kinetic energy a new twist • new directions of wind-hydro integration, hydrokinetic turbines, wave energy technologies • More testing and demonstration are needed to understand design tradeoffs (energy vs environment) • Research opportunities include environmental science and hydraulic engineering, computational fluid dynamics, and advanced materials • Hydropower is an important part of the Energy~Water Nexus Presentation_name
Adapted from: EPRI: “The Power to Reduce CO2 Emissions,” 2007. (Steam) Cleaner coal use as a sustainable technology • Coal-fired power plants are major contributors to air pollution, but they cannot be phased out quickly • Implementation of carbon management strategies on current coal-fired plants has the potential to make a large reduction in CO2 emissions in a relatively short time • aiming for best practically attainable levels (rather than 100% removal) would produce significant changes in the shortest time • the level of CO2 reduction could be ramped up as technologies evolve Presentation_name
Deep-Savings EE/RE Solutions for Buildings are Potentially Less Costly Than Business-As-Usual • Incentives may be less costly than the avoided supply-side investments Presentation_name
EE Measures Could Keep U.S. CO2 Emissions Constant to 2030 as the Economy Doubles • And RE could make deep cuts below today’s levels Presentation_name
