Save The Climate : solutions for the future, action now

What we want :

unrestricted consumption of fossil fuels is inducing, via GHG emissions, a global climate change whose foreseeable consequences are daunting. Save The Climate (SLC) seeks to bring a neutral, scientific, Cartesian contribution to the debate. SLC considers that a powerful popular movement is urgently needed that, far from ideological stands, would express the real facts and the consequences that they imply.

  • Nuclear Power reduced to 50 %:  Less Security, More CO2 (Presentation)



    A Short Presentation

    The planned decommissioning of 14 reactors by 2035 so as to reduce to 50 % the share of nuclear power has been presented as a necessary diversification, in order to "not put all the eggs in the same basket" and to better secure the country's supply. In truth, the result will be the exact opposite. Indeed, perfectly "dispatchable" production units, i.e. units capable of producing according to demand, will be replaced by wind turbines and photovoltaic panels whose production is contingent on the amount of wind or sun and is in no way related to the demand... Photovoltaic production is nonexistent at night and wind is statistically nonexistent 36 days per year on average; thus, there will be some ten long winter nights, a time of high demand, when the wind + photovoltaic fleet production will be close to zero, regardless of the installed capacity. Result: the certain effect of decommissioning 14 reactors will be to deprive the country of some 10 GW capacity several times each winter! A considerable loss, 6 times larger than the supply security margin on the grid!

  • Fessenheim: the Second Step in a Disastrous Drift




    Next June 30, the second reactor at the Fessenheim nuclear power plant will be shut down for good. This means an annual continuous production capacity of 6 TWh of decarbonized electricity will be scrapped although it could have continued to generate safe power for many years.

  • Nuclear Excluded from EU Sustainable Finance? An Aberration!


    On April 15, 2020 the European Council adopted the "green taxonomy" sustainable finance regulation, the result of a political agreement reached last December with the European Parliament. This text includes only renewable energies; nuclear power is excluded in spite of its being carbon-free. In the perspective of "Save the Climate", the taxonomy as it has been adopted supports a mix of renewable & gas for electricity generation, an environmental and economic aberration.

  • Fessenheim Nuclear Reactor Permanent Shutdown - An Immense Waste for the Climate and for the Country



                 With its decision to permanently shutdown reactor number 1 at the Fessenheim nuclear power plant, France has chosen to deprive itself of a dispatchable, carbon-free, operational electricity production unit: the reactor had the potential to last another ten years or more; no other carbon-free source of electricity production capable of compensating for this shutdown has been put in place prior to the closure. Yet, the President of the French Republic has stated loud and clear that France aims to be exemplary in the struggle against climate warming...

                Terminating this reactor represents at least a triple penalty for the country.

  • Australia: Has the War Against Climate Change Begun?



    Australia is on fire, but no one knows how to suppress the wildfires.

    Only abundant rain, in spite of the country's sophisticated technology, is susceptible to end this catastrophe. The time has come for a global call to arms.


  • Which Energy Sources to save the climate ?

     At the COP25 held in Madrid in December 2019, Sébastien Richet of GISOC (Global Initiative to Save Our Climate, created by members of Save the Climate) presented a poster in which the results of a scientific study on the element limitation factors till 2050 relative to various carbon-free energy sources are summarized. This study concludes that only nuclear power with reprocessing and Gen-IV reactors, with a complement of hydraulic power and bio-energy based on wood where applicable, can cope with the most demanding scenarios.



  • In 2020, France Must not Spoil Its Excellent "Climate Assets" pdfclic


    Let us hope that, in 2020, France will take all the possible steps to improve its climate performance and will begin a period of emissions reduction with the conversion to electricity of its mobility and its heat production for housing and offices. Let us hope that the country will not surrender to a very costly (see the Court of Auditors report) politically biased temptation to reduce its nuclear based electricity production, at the root of the country's climate excellence.

  • A Political Decision: The Early Shutdown of the Fessenheim Nuclear Power Plant[1]... an Approach à la Gribouille[2]


    RTE (the French Electricity Transmission Network Operator), the entity in charge, by delegation of the State, of balancing electricity production to demand for France, has recently published its supply forecast for the next few years.

    In it, we learn that the supply should be enough over the 2019-2020 winter, barring any intense cold spell... But things take a turn for the worse later: during the 2022-2023 winter, the situation requires "careful attention" an understatement in RTE's coded language, meaning there is a high risk of power shortage. Why? Two reasons: the definitive shutdown of the Fessenheim Plant during the first semester of 2020 (after winter), removing 1 800 MW. And, by 2022, the definitive shutdown of 3 000 MW from the five-remaining coal-fired power plants, in compliance with the recently passed energy-climate legislation, whose purpose is, rightfully, to reduce the country's CO2 emissions.

  • EU must include nuclear power in its list of sustainable sources

    This letter has been prepared under the banner of "weCARE"


    Nuclear power is the single biggest source of low carbon electricity in Europe today and is recognised by the Intergovernmental Panel on Climate Change, the IEA and other organisations as having an essential role to play in responding to the climate emergency. It is therefore vital that nuclear is included in the EU's new classification system for environmentally sustainable activities which is currently being negotiated in Brussels. The "taxonomy" is supposed to provide clear definitions to fund managers and investors about which products are environmentally sustainable and which are not. For this initiative to serve its purpose, which is to increase the volume of financial capital flowing to sustainable activities, financiers must have confidence that the definition of a sustainable activity is developed with rigour, robustness and in an objective way. However, progress is being blocked by several countries, including Germany, who claim nuclear should be excluded because of their concerns about nuclear waste. This is in spite of clear evidence that nuclear waste does not and will not cause harm to sustainability objectives.   >>>

  •  A James HANSEN Release

     figure 1 hansen

     July 2019 was the hottest month ever in the GISTEMP analysis, i.e., since 1880 when adequate instrumental data became available. July was +0.93°C relative to 1951-1980 or +1.17°C relative to 1880-1920, which is significantly warmer than prior Julys (left figure above). July was the second consecutive month of a monthly record high (right figure).  The real temperature (not anomaly) exceeded that in August 2016, which had been the warmest month.

  • The New EU Parliament - A Change of Climate?

    The outcome of the European Parliamentary elections shows that climate warming is now at the heart of European considerations. This is good news. Yet, to what extent are we unanimous on the solutions that should be implemented?

    The French Greens along with the associations they are close to (Greenpeace, WWF (World Wide Fund for Nature), FNE (France Nature Environnement a French federation of associations for the protection of nature) and others), the Syndicat des Énergies Renouvelables (federation of renewable energy industries), the public agency ADEME (French Environment & Energy Management Agency) all remark that France is lagging behind Germany in the development of renewable energies. Indeed, Germany produced 3.8 times more wind electricity and 3.9 times more photovoltaic electricity than France in 2018. However, the per capita CO2 emissions of Germany (8.88 metric tons) are twice those of France (4.38 metric tons). This observation alone shows that resorting to nuclear power for electricity generation is much more efficient in terms of CO2 emissions than resorting to intermittent renewables.

  • What Is to Be Done with Nuclear Waste?

     Hervé NIFENECKER                                                Translation by Elisabeth Huffer


    France is in a distinctive position. Almost all of the electricity it produces is carbon-free, thanks to its hydroelectricity and nuclear power. The "Sauvons le Climat"  organization endeavors to put forward the pathways that are best adapted and most efficient to further limit carbon dioxide emissions rapidly, thus mitigating the potentially considerable risks associated to uncontrolled climate warming. It is thus duty-bound to be involved in the recently launched debate on the PNGMDR (Plan National de Gestion des Matières et Déchets Radioactifs - National Plan on Management of Radioactive Materials and Waste).

    "Sauvons le Climat" which was involved in the previous debates on radioactive wastes considers it is essential, in such a complex issue, to review basic data so as to enable our fellow citizens to make an informed judgment on the impact of radioactive waste and materials, as compared to the part played by nuclear science and technology in the struggle against climate change, and also in numerous other fields, such as medicine, industry, energy independence, competitiveness.

  • German Electricity and its Negative Prices


    In this study, we discuss the results obtained from a thorough analysis of the electricity production prices displayed by Fraunhofer ISE, an "Institut für Solare Energie-systeme" on its internet site Our analysis whose title is "Negative Electricity Prices in Germany?"[1] is a comprehensive compilation and tight analysis of the Fraunhofer data covering all of 2017. The study also includes tutorial help for the curious reader in his/her navigation of this very rich site, were he/her to perform a personal verification of the exactitude of this study based on indisputable data provided by a German institute dedicated to the promotion of solar photovoltaics and the Energiewende policy.

  • Carbon Neutrality: Yes, but How?

    Carbon neutrality by 2050 is the new, ambitious, objective set by the French Government, instead of the objective that had previously been set, a division by a factor 4 of our CO2 emissions.

    Carbon neutrality is achieved by a country when the amount of CO2 absorbed in this country, either naturally or via human action, entirely compensates the emissions of that country. In its 5th report in 2013-2014, the IPCC anticipated that the global mean surface temperature increase in 2100 could be limited to 2°C provided carbon neutrality at the global scale could be reached before the end of the 21st century. The IPCC SR15 special report published in autumn 2018 stipulates that carbon neutrality will have to be achieved by 2050 if the global temperature increase is to be limited to 1.5 °C.

  • Is the French Government Turning a Deaf Ear to Youth Demanding Climate Warming Action?

     European Youth are rallying against climate warming.

    While the French government has decided to shutdown two operational nuclear reactors, we observe that it is hesitating to shutdown some coal-fired plants. The nuclear reactors are large capacity installations that produce electricity with no CO2 emissions while the coal-fired plants are, on the contrary, the installations that produce electricity with the largest CO2 emissions. Are we really intent on wanting to fight climate warming?

  • Spontaneous balancing of wind power in Western Europe: origin and limits

    1. H. Flocard[1], translated by Jean-Louis BOBIN


                Grounded on data from six Western European countries, the limits of natural balancing from the sum of wind power productions over several thousand-kilometre distances are investigated. We show that data and the associated balancing are satisfactorily reproduced using simple probabilistic laws. Observations and the subsequent analysis show that the hoped for smoothing of wind power production fluctuations does not happen. Consequently, the foreseen implementation of a high voltage network across national borders is not considered as a valuable contribution to overcome the drawbacks of wind power in the management of the national and European grids.

  • Health Impacts of the Different Energy Sources

    Energy in all its forms is an essential element of life in our societies. However, along with the many benefits it provides, every stage of its implementation has negative repercussions.

    At a time when a growing sensitivity is developing to control and reduce the consequences of human activities that are detrimental to the environment, the production and use of energy are subjected to close scrutiny. Similarly, weighing the various sources of energy involved with regard to their impacts on public health proves to be essential.



  • Translation of  La stratégie bas carbone de la Suède by Jean Fluchère

    France always puts Germany forward as a model but Germany's "Energiewende" is an obvious failure as even France Stratégie[1] recognizes.

    On the contrary, we have a remarkably successful low carbon strategy example with Sweden and its 10 million residents.

    As early as 1991, Sweden embarked upon what we now call a low carbon strategy.
