It has been predicted that by 2030 the world’s population will be about 1.6 times that of 2004. The energy consumption will increase by 60% by 2030. This new book discusses the Wind turbine generation and photovoltaic power generation which are expected to increase ten-fold by 2030, but their combined percentage of the generation will only total 7%. The expectation for nuclear power generation is large, but under present conditions, the amount of natural uranium resources will have a share for only 80 years. Development of the fast breeder reactor is being pushed forward, but it is not expected to be commercial before about 2050. Therefore, it will continue to be necessary to depend on fossil fuel. Carbon dioxide capture and storage (CCS) techniques for thermal power plants will also surely become important.
