that region. Transporting this coal or transmitting this electrical power to the coastal regions would result in higher charges for electricity consumed in those locations. In contrast, the nuclear options (LWR, LMFBR, and fusion) could be sited in any region, minimizing the differences in macroeconomic effects between regions. TPV is most economically located in areas of high insolation. These are primarily in the South and Southwest. Deployment at a significant level relative to national electrical energy needs could result in long-haul transmission, as in the case of low-sulfur western coal, and subsequently higher prices to consumers in other areas. It may be possible to site SPS rectennas in every region in the U.S. This would minimize regional differences just as the nuclear options would. However, if it became necessary to transmit SPS power for long distances due to local siting difficulties (or any other reason), regional differences would result. 4.6.3 Socioeconomic Comparisons The focus of the socioeconomic analysis is on labor requirements of the various technologies, with some comments on potential "boomtown” effects. Table 4.47, compiled from technology characterization data in Sec. 3.2, lists the labor requirements of the energy technologies. The average number of people on site during construction and during operation (for operations and maintenance) are given along with construction time. The entries for SPS include only the rectenna site. The figures given for construction are for the average work force per year over the construction interval. The peak work force would be somewhat higher (by about 30%) than this. Furthermore, families would Table 4.47 Energy Technology Labor Requirements
