Figure F Impact of wind technology improvements

The achievement of these research goals would lead to cost reductions that can be viewed from two perspectives. On the one hand, the available land areas for cost-effective machines (i.e., 50 kWh) would be substantially increased. On the other hand, if a wind farm can produce electricity for 50 kWh at a good site, then it can produce electricity for 30 to 40 kWh at better sites. Excellent wind sites, while less common than the good sites, can provide an economic wedge to begin penetration of...

Renewable Energy Technology Today

Renewable energy technologies are being developed to produce marketable energy by converting natural phenomena into useful energy forms. These technologies use the energy inherent in sunlight, the direct and indirect results of its impact on our planet photons, wind, falling water, temperature differentials, and plant matter , gravitational forces the tides , and the Earth's heat as resources for producing energy. These resources represent a massive energy potential see Table II-1 that dwarfs...

Estimates of the RET Contribution Potential

Estimates of RET contribution potential depend on several first-order considerations. The first is resource availability. In order to expect any level of contribution from a particular RET, the resource must exist to be exploited. Further, it must be of sufficient intensity that the RET can produce energy at or below the price of competing resources. Second, the RET must be able to supply energy in a form that can be effectively used in energy-consuming sectors. For example, to penetrate the...
