Situation of nuclear energy in the world

Situation of nuclear energy in the world

Nuclear energy began to develop during the first decade of 1940. Initially, the research was aimed at the development and production of the atomic bomb. Subsequently, research began on other applications of nuclear energy; the investigation focused on the peaceful use of nuclear energy.

Currently, there are 30 countries in the world that have nuclear power plants for the generation of electricity. In any case, the number of countries that take advantage of nuclear energy is much greater since countries such as Denmark and Italy, which do not have any nuclear facilities, obtain about 10% of their electricity from nuclear energy imported from other countries.

Worldwide, about 450 nuclear power reactors are operating. All these reactors together generate around 11% of the electrical energy consumed in the world. However, 60 more reactors are currently being built. Which would increase the power generated through nuclear energy by 16%.

In 2016, nuclear power plants supplied 2477 TWh of electricity, compared to 2441 TWh in 2015.

World electricity production in 2015

According to data from the IEA Electricity Information of 2017, the main source of electricity generation was coal. Coal-fired power plants accounted for 39.3% of the world's electric power. In second position is the gas power plants, with 22.9%. Next, with 16% is the hydraulic energy, the first source of renewable energy that appears in the list. Then we found nuclear energy, with 10.6%.

Finally, with a more discrete percentage we find certain renewable energies. 4.9% of the electric power generated in the world is produced by solar energy, wind energy and geothermal energy. Next, 4.1% of electricity is generated by burning oil and 2.2% is generated by other systems.

This implies that non-renewable energies continue to have a majority share in the generation of electricity in the face of renewable energy worldwide.

In the classification of countries with the highest production of electricity through nuclear power plants, we find the United States in the first position, which in 2016 generated 805 TWh (one hour watt). The following countries in nuclear energy production are: France, China, Russia, South Korea, Canada, Ukraine, Germany, United Kingdom, Sweden, Spain, Belgium, India, Czech Republic, Finland, Switzerland, Japan, Brazil, Bulgaria, Hungary , South Africa, Slovakia, Mexico, Romania, Argentina, Iran, Pakistan, Slovenia, the Netherlands and Armenia.

Four AP1000 reactors had been built, but two of them have stopped. One of the reasons for the hiatus in new construction in the United States to date has been the extremely successful evolution in maintenance strategies.
