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.
Renewable energy alternatives also exist. These include solar energy, wind energy, geothermal and hydroelectricity as well as other sources. These sources are said to have much lower emissions, and almost minimal secondary by products. The production of renewable energy is projected to grow in nearly every region in the World. [78]
The study also found that the environmental and health costs of nuclear power, per unit of energy delivered, was €0.0019/kWh, which was found to be lower than that of many renewable sources including that caused by biomass and photovoltaic solar panels, and was thirty times lower than coal at €0.06/kWh, or 6 cents/kWh, with the energy ...
These are usually sources of only electrical energy but sometimes sources of heat are evaluated. [1] The findings are presented in units of global warming potential per unit of electrical energy generated by that source.
Emissions arise from several sources. These include CO 2 released by the decomposition of the kerogen and carbonate minerals in the extraction process, the generation of the energy needed to heat the shale and in the other oil and gas processing operations, and fuel used in the mining of the rock and the disposal of waste.
During the 20th century, energy consumption rapidly increased. Today, about 80% of the world's energy consumption is sustained by the extraction of fossil fuels, which consists of oil, coal and natural gas. [4] Another non-renewable resource humans exploit is subsoil minerals, such as precious metals, mainly used to produce industrial commodities.
The role of non-renewable energy sources in sustainable energy is controversial. Nuclear power does not produce carbon pollution or air pollution, but has drawbacks that include radioactive waste , the risk of nuclear proliferation , and the risk of accidents .
The depletion of resources has been an issue since the beginning of the 19th century amidst the First Industrial Revolution.The extraction of both renewable and non-renewable resources increased drastically, much further than thought possible pre-industrialization, due to the technological advancements and economic development that lead to an increased demand for natural resources.
