Chapter 17 SOLAR ENERGY - Pennsylvania State University
Chapter 17 SOLAR ENERGYR enewable technologies represent an important opportunity, but not a panacea for the economy. Their long-term contribution is predicated on overcoming remainingtechnical and cost barriers, mainly through intensified R&D. The National EnergyStrategy's renewable ENERGY initiatives are based on these conclusions and on a clearunderstanding of the contributions that renewable ENERGY can and cannot be expected tomake. For example, given policies to address existing regulatory barriers and marketimperfections, SOLAR thermal or photovoltaic electricity technologies can compete today toprovide electricity generation in remote locations and for peaking purposes.
Chapter 14 we discussed nuclear fusion; it could solve all our energy problems, but many technical problems need to be overcome before it can be harnessed and commercialized. The production of electricity using fusion must go through the ‘bottleneck’ of thermal-to-mechanical energy conversion, which is inherently inefficient.
