This is the gray energy of uranium, to which we can add that of the concrete plants, among others.
I point out that for wind turbines it's not better.
Climate: CO2 releases decline in China and the United States
By Fabrice Nodé-Langlois The Figaro the 17 / 03 / 2017
Global greenhouse gas emissions from production are stable for the third year in a row. Better, they fell in 2016 in the United States and China. Partly thanks to shale gas.
This is good news for the planet. For the third consecutive year, emissions of CO2 (carbon dioxide, the main greenhouse gas) in the world have remained stable. Better still, greenhouse gas emissions are declining among the first two polluters, China and the United States. This finding of the International Energy Agency (IEA) focuses only on CO2 emissions related to energy production, so does not take into account transportation, industry or agriculture.
Gas displaces coal in the United States
It is in the United States that the decline in carbon emissions is most marked, notes the IEA. They dropped by 3%, which is 160 million tonnes less carbon sent to the atmosphere. This improvement, in terms of pollution, is partly explained by the increase in renewables in America but especially because of the continuing growth of shale gas. Gas is a fossil fuel, which emits CO2 when burned, but much less than coal. For the first time this year, electricity generated in gas-fired plants has outstripped that from coal-fired plants. US emissions have returned to their level of 1992 while since this year US GDP has increased by 80%. The decoupling between production of economic wealth and fossil energy production has indeed taken place.
New atomic reactors in China
In China, CO2 releases decreased by 1%. Two-thirds of the increase in electricity demand last year was met by renewables (mostly hydro and wind) and nuclear. No less than five atomic reactors entered service in China in 2016. The use of natural gas is increasing in China as well, but it still represents only 6% of the energy mix, against 25% on average in the world.
Globally, more than half of the year's additional consumption was met by renewables, with hydropower still accounting for the lion's share of clean energy. Six years after the Fukushima disaster, nuclear power is experiencing dynamic growth as its global capacity has grown better since 1993 with the launch of new reactors in China, Russia, the United States, South Korea, India and India. in Pakistan.
This stabilization observed while global economic growth has increased in 2016% 3,1 "signals a beginning of trend that leads to optimism even if it is too early to say that global emissions have reached their peak," said Fatih Birol , the director general of the IEA.

The structural functioning of a system that is progressively infected allows us to understand this relative sluggishness.

Physical limitations in the end make almost all the work, the rest is green washing.
