Investment in the first new nuclear plant to be built in the UK in 20 years - at Hinkley Point, Somerset - has secured final approval.
Following that agreement, legally binding contracts will be signed and construction work can begin.
But critics warn of environmental damage and potential escalating costs.
They are also concerned that the plant is being built by foreign governments. One third of the £18bn cost is being provided by Chinese investors.
EDF hopes to have more than 2,500 workers on site by next year.
Announcing the approval of investment, EDF described the plant as "a unique asset for French and British industries", saying it would benefit the nuclear sectors in both countries and would give a boost to employment.
