Renewable energy is derived from natural processes that are replenished constantly. In its various forms, it derives directly from the sun, or from heat nuclear energy definition pdf deep within the earth. Renewable energy resources exist over wide geographical areas, in contrast to other energy sources, which are concentrated in a limited number of countries. In ISO 13602-1:2002, a renewable resource is defined as “a natural resource for which the ratio of the creation of the natural resource to the output of that resource from nature to the technosphere is equal to or greater than one”.
Nuclear fission reactors are a natural energy phenomenon, having naturally formed on earth in times past, for example a natural nuclear fission reactor which ran for thousands of years in present-day Oklo Gabon was discovered in the 1970s. Conventional, human manufactured, nuclear fission power stations largely use uranium, a common metal found in seawater, and in rocks all over the world, as its primary source of fuel. A cutaway model of the 2nd most powerful presently operating fast breeder reactor in the world. In 1983, physicist Bernard Cohen claimed that fast breeder reactors, fueled exclusively by natural uranium extracted from seawater, could supply energy at least as long as the sun’s expected remaining lifespan of five billion years. Presently, as of 2014, only 2 breeder reactors are producing industrial quantities of electricity, the BN-600 and BN-800. Estimates of Available Uranium-235, an isotope required for the present world fleet of light water reactors, that is, not the uranium-238 feedstock needed for some breeder reactor designs, one of which was discussed above.
Known economic reserves, a figure that has increased from 80 to over 100 years after this estimate was made in 2005. The world’s measured resources of uranium-235 in 2014 was estimated to be enough to last over 135 years at 2014 consumption rates. Inclusion under the “renewable energy” classification as well as the low-carbon classification could render nuclear power projects eligible for development aid under more jurisdictions. A bill proposed in the South Carolina Legislature in 2007-2008 aimed to classify nuclear power as renewable energy.
The bill listed as renewable energy: solar photovoltaic energy, solar thermal energy, wind power, hydroelectric, geothermal energy, tidal energy, recycling, hydrogen fuel derived from renewable resources, biomass energy, nuclear energy, and landfill gas. In 2009 the Utah state passed the bill ECONOMIC DEVELOPMENT INCENTIVES FOR ALTERNATIVE ENERGY PROJECTS including incentives for renewable energy projects. The bill passed the house with 72 yeas, 0 nays, and 3 absent, passed the senate with 24 yeas, 1 nay, and 4 absent, then received the governor’s signature. In 2010 the Arizona Legislature included nuclear power in a proposed bill for electric utility renewable energy standards.
The bill defined “renewable energy” as energy that is renewable and non-carbon emitting. It listed solar, wind, geothermal, biomass, hydroelectric, agricultural waste, landfill gas and nuclear sources. In 2015 the Arizona bill specified that “Nuclear energy from sources fueled by uranium fuel rods that include 80 percent or more of recycled nuclear fuel and natural thorium reactor resources under development” are renewable. Nuclear energy has been referred to as “renewable” by the politicians George W. Bush, Charlie Crist, and David Sainsbury. London: Parliamentary Office of Science and Technology.

Our Common Future: Report of the World Commission on Environment and Development. Today’s primary sources of energy are mainly non-renewable: natural gas, oil, coal, peat, and conventional nuclear power. There are also renewable sources, including wood, plants, dung, falling water, geothermal sources, solar, tidal, wind, and wave energy, as well as human and animal muscle-power.
