<研究ノート>Efficiency Electricity for the Environment and the Economy

Abstract

This paper presents the case for increased energy efficiency not only as a way to reduce global warming but also as a way to achieve economic benefits. The case for energy efficiency is illustrated with examples of lighting, appliances, efficiency gains in businesses, and efficiency in the production of electricity. Electricity can be produced at up to 90%efficiency through cogeneration systems compared to the 33%efficiency of standard power plant produced electricity by the time it is delivered to the user. Efficiency is economical and suitable for both the developed and developing world. Rather than being an expensive way to respond to global warming, efficiency is a money saving way to protect the earth. Finally, in order to increase the use of efficiency three steps are necessary. First, information and education about efficiency is needed. Secondly, governments should reduce subsidies that encourage wasteful energy use. Third, consumers need to choose efficiency when making decisions related to energy.
