FAQ

How does nuclear energy compare with other energy sources?

Answer

Nuclear power emit very limited green gases and therefore helps and will even help more in the future to limit COemissions, a condition to reduce climate changes. It is economical, safe and reliable. It contributes to security of energy supply.

Background

Nuclear power provides large scale energy supply and is an important part of the solution to meet the world’s ever increasing demand for energy. Nuclear energy is cost competitive with other forms of electricity generation, except where there is direct access to low-cost fossil fuels. It is a mature and safe technology, it contributes to security of energy supply, and It has a low impact on the environment. Furthermore it contributes to a more equitable access to energy and thus to social and economic development which could constitute an ethical argument in favour of nuclear power.
Energy production has to meet three criteria: accessibility - access to affordable modern energy for all people, availability - reliable and secure energy supply acceptability - protect and preserve the local and global environment.
Fossil fuel (coal and gas) will also be needed to meet electricity demand but for coal CO2 sequestration will become soon a must and the industrial application is not yet available, prices of electricity by this technique are not known. For gas, the major problem is security of supply for geopolitical reasons. 
All renewable sources will also be needed but will never achieve the high power density that you find in a reactor. Their capacity factors should be increased.  Wind power is linked to availability of wind and needs compensation through fossil fuelled plants when stopped.
