Project Wind

Other sources of energy worth noting are the extensive wind farms, solar projects, and related emerging unconventional technologies. These renewable resources provide only small quantities of energy to the U.S. economy as of this writing.

Floating hollow spheres are made of polypropylene with projections to prevent rotation. They restrict oxygen absorption and reduce emissions with an effectiveness of 80 to 90 percent. High winds can pose serious problems by blowing the spheres away (University of Arkansas and Louisiana State University, 1985). 

Project delineates between cleaner new gas technologies and polluting old natural gas technologies—and reserves a third cleanest category for energy efficiency/conservation, solar, wind, and geothermal (but not hydro or biomass). 

The annual LCOE for wind turbines has decreased dramatically since 1980. At that time, the LCOE was 0.35/kWh. In 1998, wind power plant projects were bid from 0.03kWli to 0.06/kWli. These numbers still exceed similar figures of merit... 

A = Total area, in ft, projected on a plane, perpendicular to the direction of the wind, except that the exposed areas of two opposite sides of the mast or derrick shall be used. 

This chapter summarizes climate projections presented by the recent Fourth Assessment Report (AR4) of the IPCC, both for the global scale and for the so-called European and Mediterranean region. Besides the IPCC projections, other results regarding the Mediterranean area will be reviewed as well. The emphasis will be mostly placed on temperature and precipitation projections, while other variables, such as wind, solar radiation, or sea level, will not be commented in depth. Some attention will be paid to methodologies used to develop projections, and the corresponding uncertainties will be commented. In general, projections will be given for the end of the current century. 

The extreme events which have been discussed differ in their characteristic spatial scales of importance. Each event which causes wind-throw occurs on a smaller spatial scale than a pollution event, as recently seen by the very extensive scale of the Chernobyl fallout (Johnston, 1987). At an even greater scale, the projected extent of the nuclear winter will be global (Covey, 1987). Examples of this hierarchy of scales of events are shown in Table 1. 

Figure 31.4 shows the biplot of the trace elements and wind directions for the case when a = p = 0.5. Since here we have that a + P equals 1, we can reconstruct the values in the columns of the data table X by means of perpendicular projections upon unipolar axes. In Fig. 31.4a we have drawn a unipolar axis through Cl. Perpendicular projection of the four wind directions upon this axis reconstructs the order of the concentrations of Cl at the four wind directions as listed in Table 31.1. Now we have established a way which leads back from the graphic display to the tabulated data. This interpretation of the biplot emphasizes the one-to-one relationship between the data and the plot. Such a relationship is also inherent in the ordinary bivariate (or Cartesian) diagram. 

In Fig. 31.4b we have constructed a bipolar axis through Cl and Si. Perpendicular projections of the wind directions upon this axis are in the same order as the... 

Revegetation is a cost-effective method to stabilize the surface of hazardous waste disposal sites, especially when preceded by capping and grading. Revegetation decreases erosion by wind and water and contributes to the development of a naturally fertile and stable surface environment. It may be part of a long-term site reclamation project, or it may be used on a temporary or seasonal basis to stabilize intermediate cover surfaces at waste disposal sites. 

In theory, the application of radon barriers should be adequate to avoid elevated radon levels in houses. In practice, however, a backup radon mitigation system has been found essential for maintaining indoor radon concentrations below 4 pCi/L in most homes studied. In the recent radon-resistant residential construction projects conducted by U.S. EPA and/or private builders, several of the homes designed to be radon resistant have contained radon concentrations above 4 pCi/L. In each of those houses, a backup system consisting of an active (fan-assisted), or passive (wind-and-stack-effect-assisted), SSD system was installed at the time of construction. When mechanical barriers failed to adequately control radon, the soil depressurization methods were made operational.

During 2004 and 2005, four major wind-hydrogen projects have been launched in Europe the Utsira project in Norway the HARI project at Loughborough the promoting unst renewable energy project in Unst, UK and the RES2H2 project in Greece and Spain. 

In the "PURE" project on the Shetland Islands, the wind-hydrogen system is composed of two wind generators of 15 kW power each, a 15 kW advanced alkaline electrolyzer operating at 55 bars, a 16-cylinder stack of 44 Nm3 H2 capacity at the same pressure, and a 5 kW PEM fuel cell [54],...
