Coal, produced over millions of years, is a finite and non-renewable resource on a human time scale. A non-renewable resource (also called a finite resource) is a natural resource that cannot be readily replaced by natural means at a pace quick enough to keep up with consumption. [1] An example is carbon-based fossil fuels.
The most common fuel used in conventional nuclear fission power stations, uranium-235 is "non-renewable" according to the Energy Information Administration, the organization however is silent on the recycled MOX fuel. [3] The National Renewable Energy Laboratory does not mention nuclear power in its "energy basics" definition. [4]
Nuclear energy and renewable energy have reduced environmental costs by decreasing CO 2 emissions resulting from energy consumption. [ 2 ] There is a catastrophic risk potential if containment fails, [ 3 ] which in nuclear reactors can be brought about by overheated fuels melting and releasing large quantities of fission products into the ...
This is the fissile isotope of uranium and it makes up approximately 0.7% of all naturally occurring uranium. [13] Because of the small amount of 235 U that exists, it is considered a non-renewable energy source despite being found in rock formations around the world. [14]
Resource depletion is the consumption of a resource faster than it can be replenished. Natural resources are commonly divided between renewable resources and non-renewable resources. The use of either of these forms of resources beyond their rate of replacement is considered to be resource depletion. [1]
A fission nuclear power plant is generally composed of: a nuclear reactor, in which the nuclear reactions generating heat take place; a cooling system, which removes the heat from inside the reactor; a steam turbine, which transforms the heat into mechanical energy; an electric generator, which transforms the mechanical energy into electrical ...
Different isotopes have different behaviors. For instance, U-235 is fissile which means that it is easily split and gives off a lot of energy making it ideal for nuclear energy. On the other hand, U-238 does not have that property despite it being the same element. Different isotopes also have different half-lives. U-238 has a longer half-life ...
For each unit of energy produced, nuclear energy has caused far fewer accidental and pollution-related deaths than fossil fuels, and the historic fatality rate of nuclear is comparable to renewable sources. [115] Public opposition to nuclear energy often makes nuclear plants politically difficult to implement. [126]
