An updated analysis of the 2005 Energy Efficiency Potential Study completed by KEMA for the Kauai Island Utility Cooperative (KIUC), which identifies potential energy efficiency opportunities in the residential sector on Kauai.
Traditional electrical lighting consumes almost 15 percent of household electricity on average, while using readily available alternative lighting technologies can reduce energy use by 50 to 75 percent.
By reducing the need for electric light, daylighting can substantially lower home energy use. Since excessive daylighting can increase both heating and cooling loads, a balanced approach is needed which involves whole building design.
This low maintenance house, built in Cannon Beach, Oregon, produces as much energy as it uses. This home incorporates a number of basic technologies in an innovative way to produce heat, hot water, and electricity.
Improving the energy efficiency of buildings and industrial facilities as winter approaches will not only save on utility bills, it will also prevent carbon dioxide emissions and improve the reliability of the nation's energy supply.
