Nuclear power

Central nuclear

Nuclear fuels are used in plants to produce electricity. A large amount of heat is obtained from the process of fission of plutonium or uranium, which is then used to heat water and produce steam, which in turn is passed through a turbine to generate electricity.

This source is very energy-intensive, so it can provide an enormous amount of energy in a relatively compact space, without producing greenhouse gases in the process. Nevertheless, the radioactive waste produced remains active for years and must be managed for storage under sealed conditions.

Countries such as France made a clear commitment to this form of electricity generate and made great investments in the construction of over 58 reactors across the country in 19 nuclear power plants. In 2011 Germany, the first European industrial power, decided to take all its nuclear power plants out of service by 2022.

Nuclear fusion

Although still at an incipient phase of research, this technology would be a great step forward in obtaining clean energy in the future. It would also avoid the problems created by the disposal of radioactive waste from fission.

Nuclear energy (fission)


  • Low land occupation. Produces a large amount of energy in a small space.
  • Continuous energy is obtained, and in large amounts.
  • CO2-free, so a strong tool against the greenhouse gas effect.


  • Scarcity of raw materials.
  • Produces hazardous radioactive waste that remains active for thousands of years.
  • Although accidents are rare, they have serious consequences.
  • Despite being a proven and mature technology, its safety largely depends on the human factor.
