The energy production is a process that is critical for most activities of the human being on earth, and also for goods produced for consumption and production. The human body itself is capable of producing energy for the activities it carries out, but not for the potential of the objects that have been formed throughout the extensive process of civilization.
Energy sources are the sum of the existing resources in nature from which people can obtain energy to use in these activities, and it is divided basically into two groups.
Examples of non-renewable energy
The non – renewable energy or conventional is obtained from limited natural resources, once totally consumed offer no possibility of being substituted. There are a number of reserves in the world for this form of obtaining energy, but nothing beyond that.
It is common for the means to produce these energy sources to be burning fossil fuels, which releases large amounts of greenhouse gases, contributing to global warming.
Some examples of non-renewable energy:
- Natural gas: Fuel of fossil origin, which is a mixture of light hydrocarbons composed mainly of methane, nitrogen, carbon dioxide, and methane. It is located underground or under the sea and must undergo a double transformation from its extraction to its possibility of effective use.
- \Petroleum: Organic compound present in different deposits, whose formation takes hundreds of millions of years. After extraction, it must be separated from gas and water through the process known as refining.
- Coal: Mineral of organic origin, consisting mainly of carbon. It also takes millions of years, and its energy use is made in thermal or thermoelectric plants to generate electricity: its steam can reach a temperature close to 600 ° C:
- Nuclear fuels: Materials that through fission or fusion release different types of energy, usually thermal. The technology that uses these energy sources is called nuclear technology, and X-rays and gamma rays appear as an example. The main nuclear fuels are uranium and plutonium.
