Better Technology Promotes Wind Power Use: On the 1920s and 1930s, farm families in the Midwest used wind to generate enough electricity to power their lights and electric motors. After rural electrification in the 1930s and 1940s, however, wind-generated electricity became much less common. Technological advances that have cut production costs, the need to comply with...; Tags: wind energy, global warming; Case studies
Windmill Power: The village of Elmore began using windmill power in November to provide electricity to a small percentage of homes. In November, Elmore began participating in an energy program called the Wind Farm project to receive a small percentage of their electricity from two windmills located just east of Bowling Green....; Tags: wind farm; Case studies
County Health Department Taps Sun's Power for Electric Needs: The Athens City/County Health Department is now using solar power, thanks to grant funding and the work of an Athens County business. The solar panels will provide backup electricity to the refrigerators that hold vaccines. The panels collect solar electricity and then store it for use if the main electricity...; Tags: Backups, HEALTHCARE, Telecom & Utilities, Vertical industries, solar energy, vaccine, backup, health care; Case studies
Complementarity Problems In Restructured Natural Gas Markets: The restructuring of the gas industry did not so far generate the same modeling activity as in electricity. While the literature of activity in electricity market models is now abundant, it is still rather scant on the gas side. This paper explains some of the existing models and attempts to...; Tags: University of Maryland, modeling, knowledge, industry; White papers 2005-05-09
electricity Retail Price Fact Sheet: The restructuring of the electric power industry is transforming the historically monopolistic industry into one that will have increased competition in its generation and retail sales components, thereby changing the way electricity is priced, traded, and marketed in the United States. This fact sheet focuses on the retail electricity market...; Tags: Sales strategy, Sales force management, Department of Energy, sales, industry; White papers 2004-10-27
Renewable electricity in the Netherlands: The Dutch policy goal is to achieve a share of 17% renewable electricity in the domestic demand in 2020. It is uncertain whether and under which conditions this aim can be achieved. This paper aims to explore the feasible deployment of renewable electricity production in the Netherlands until 2020 by...; Tags: Netherlands; White papers 2004-09-23
How the electricity Grid Works: Controlling the Power Grid: Electricity is generated as it is used. There is very little ability to store electricity. Because of this instantaneous nature, the electric power system must constantly be adjusted to ensure that the generation of power matches the consumption of power. Although Control Area Operators run the grid within their control...; Tags: U.S. Department of Energy, grid; White papers 2004-07-13
