Abstract: | Appropriate technology for energy supply requires the use of the most effective energy resources and conversion technologies that will also result in the minimum acceptable impact upon the environment. A useful parameter for evaluation of energy resources for large-scale production of electricity and hydrogen fuel is the specific energy of the appropriate energy resources. Available resources for such large-scale applications must come from some mixture of renewable, fossil, and nuclear energy. Analysis is made of the appropriate use of solar energy, chemical combustion fuels, and nuclear energy on the basis of their specific energy. The results show that the most appropriate resources for large-scale production of electricity and hydrogen are low-specific solar photovoltaic and wind turbine energy for large numbers of distributed small-scale applications and high-specific nuclear energy for smaller numbers of large-scale applications. |
