A detail too, to raise the water you need a hell of a bundle of energy that only a nuclear power plant can provide today.


It is quite possible to use wind power for "pumped storage" (in Spain, there is a device of this kind).
The "overflows" of energies, during strong windy episodes, are used to pump water into a reservoir, which is released when there is a stronger demand on the network.


To my knowledge, there is a project of this kind (STEP *) in Corrèze, the installed power would be 1100MW.
It will therefore be enough to install 1100 wind turbines of 1MV, that there is wind when it is necessary and that we do not need the electricity that they produce at that time .... In short no need for a drawing

Or, we install 5 wind turbines, it fills a "basin", it costs a small fortune, it produces 0,0 ...% of what we need and the ecologists are happy : Lol: finally as usual.

New technologies are emerging that could quickly change the economic picture
as a higher temperature photovoltaic combined with thermal energy with an efficiency of more than 50%!

New solar energy conversion process could revamp solar power production
http://www.physorg.com/news199962208.html

Photon-enhanced thermionic emission for solar concentrator systems
http://www.nature.com/nmat/journal/vaop ... t2814.html
Solar-energy conversion usually takes one of two forms: the 'quantum' approach, which uses the large per-photon energy of solar radiation to excite electrons, as in photovoltaic cells, or the 'thermal' approach, which uses concentrated sunlight as a thermal-energy source to indirectly produce electricity using a heat engine. Here we present a new concept for solar electricity generation, photon-enhanced thermionic emission, which combines quantum and thermal mechanisms into a single physical process. The device is based on thermionic emission of photoexcited electrons from a semiconductor cathode at high temperature. Temperature-dependent photoemission-yield measurements from GaN show strong evidence for photon-enhanced thermionic emission, and calculated efficiencies for idealized devices can exceed the theoretical limits of single-junction photovoltaic cells. The proposed solar converter would operate at temperatures exceeding 200 ° C, enabling its waste heat to be used to power a secondary thermal engine, boosting theoretical combined conversion efficiencies above 50%



Another interesting discovery is a new simple compound to decompose water with light and make hydrogen:

http://www.physorg.com/news195231833.html

have demonstrated that a simple inorganic compound, silver orthophosphate, can efficiently be used to oxidise water with only the power of light. The oxidization process can be used to convert solar energy to clean energy or break down contaminants in water. The research is published in Nature Materials.

this time, Germany really decides to get out of nuclear power.

The end of nuclear law approved by the German Parliament

July 08, 2011 Usine Nouvelle

The Bundesrat validated the law providing for the end of nuclear power in the country on July 8. A measure that definitively endorses the project.

Unsurprisingly, the upper house of the German Parliament has endorsed the government's plan to halt the development of nuclear energy in the country following the Fukushima disaster.

In detail, the law was approved by an overwhelming majority of representatives of regional states. This vote follows that of the lower house of Parliament during the week.

This law provides for the end of operation of the last nuclear reactor in Germany at the latest in 2022. Seven reactors have already been shut down after the Japanese disaster and another will not be reactivated. For the other nine, the law provides for their progressive cessation between 2015 and 2022.

At the same time, the Bundesrat has adopted a series of complementary measures, such as the construction of new coal-fired and gas-fired thermal power stations which are expected to make up for the energy shortfall. Indeed, nuclear power provides 22% of total electricity in Germany.

Germany to finance new coal-fired power plants with climate fund

Many experts doubt that Germany can at the same time leave nuclear power and reduce its greenhouse gas emissions by 40% by 2020.

The German government wants to help finance the construction of new coal and natural gas power plants with hundreds of millions of euros to promote clean energy and the fight against climate change.

They are preparing for it, but it is a "last resort". According to all the ratings.

And also because they set the bar very high with a very short delay.

Nuclear and climate change: Stop misconceptions!
Climate: what do scientists say?

According to the international scientific community, the rise in the average temperature of the globe must be kept below + 2 ° C to avoid the most catastrophic effects of climate change. To this end, global greenhouse gas emissions must be reduced by at least 80% by 2050, compared to 1990. As for the industrialized countries, the first emitters of greenhouse gases, they must have already reduced their emissions by 40% by 2020! [1]
Technology "off topic" and inefficient

75% of global greenhouse gas emissions come from sectors unrelated to electricity production, or for which using electricity is particularly poor: agriculture, forestry, industrial processes, transport, heating, etc. [2]. Nuclear is therefore irrelevant!

Its ability to reduce the remaining 25% of emissions is extremely poor. Far from being anti-nuclear, the International Energy Agency encourages, against all reason, the continuous growth in energy consumption. However, it calculates that the contribution of nuclear power to the reduction of CO2 emissions would be barely 6% at a cost of at least 1 billion euros ... against 000% for energy savings and 54% for renewable energy, at a much lower cost! [21]

Since it takes about 10 years to build a single reactor, this derisory and hypothetical reduction would not start until after 2020, so far too late.
Yes, nuclear emits greenhouse gases!

The nuclear industry emits significant quantities of greenhouse gases, linked to the life cycle of the reactors (construction, dismantling, etc.) and their fuel (extraction, transport, reprocessing, etc.). But above all, unlike other technologies, nuclear power does not recover the heat released during the production of electricity. It therefore requires producing additional energy for our heat needs. Producing electricity and heat in co-generation makes it possible to emit 7 times less greenhouse gases than a nuclear energy system! [4]
Nuclear: expensive ... and counterproductive!

For one euro invested, energy efficiency and certain renewable energies are up to 11 times more efficient than nuclear to reduce greenhouse gases! [5] However, nuclear technology is a real financial chasm. As a result, it hampers the rapid and massive development of real solutions against climate change.

Indeed, nuclear power requires considerable investments in infrastructure and monopolizes huge public subsidies, including 2/3 of the European research budgets on energy. [6] Since 1974, OECD countries have officially spent 55% of their energy research budgets on nuclear, or $ 250 billion. [7] The future costs of dismantling nuclear installations and managing radioactive waste will amount to hundreds of billions of euros.
Power plants vulnerable to climate change

The warmer it is, the less operational the nuclear reactors: 1/4 of the French nuclear fleet had to be shut down in 2003 because of the summer heat wave! In addition, nuclear consumes 25 times more water per kWh produced than wind and solar energy. [000] Extreme climatic events (storms, floods, etc.), which are increasing in frequency, increase the risk of accidents. Thus, in 8, the French nuclear power plant of Blayais, which borders Bordeaux, came close to disaster due to a flood, and the city was nearly evacuated. [1999] Flooded by the tsunami of December 9, 26, the Indian power station of Kalpakkam was urgently shut down. 2004 families were reportedly evacuated the next day as a precaution. Worrying levels of radioactivity were measured 15 months later in an area of ​​000 km around. [2]
A polluting and dangerous industry

In normal operation, the nuclear industry pollutes water and soil, particularly during uranium mining. It constantly releases radioactivity into the environment. A German scientific study has shown an increase of 117% of childhood leukemia up to 5 km from certain plants. [11] The very official International Commission on Radiological Protection itself affirms that "any dose of radiation carries a carcinogenic and genetic risk". [12] A major accident, always possible, would contaminate vast areas for thousands of years, and there is no solution to managing nuclear waste. Finally, the proliferation of nuclear reactors favors the proliferation of atomic weapons.
Create more jobs with other energies

In less than 10 years, Germany has created nearly 300 jobs in renewable energy [000]. This still emerging sector already employed at least 13 million people worldwide in 2,3. Industrialized countries are not alone in benefiting from this, and some are developing some of the most dynamic solar energy programs in the world. Thus, 2008 photovoltaic roofs have been installed in a few years in Bangladesh, and this sector could create 100 jobs in the country by 000. [100] With equal investment, energy savings and renewable energies create 000 times more jobs than nuclear! [2015]
The real solutions exist, let's use them!

Many relevant measures must be implemented in terms of energy policy (energy efficiency, energy savings, development of renewable energies, etc.), but also in other sectors: fight against deforestation, transition to sustainable agriculture, relocation of economic activities,… Without forgetting the reduction of methane emissions, a gas that heats 49 times more than CO2. Its recovery from French landfills would avoid far more greenhouse gases than the construction of 3 EPR reactors! [16]

Numerous studies [17] have shown that the energy alternatives already available would make it possible both to fight climate change effectively and to do without nuclear electricity entirely… which today represents only 2,4% of energy consumed in the world! [18]

Please give the source of the citation with the link to this basic analysis that all French people should read and assimilate !!!!

There is a lack of heating, without CO2 or pollution in perpetuity, thanks to the free and wasted summer solar heat currently stored for the winter.

This solar heat is currently completely wasted in summer and therefore the detractors who say that we will lose too much by storing, are not consistent, because the part recovered in winter, even if less than that stored in winter, reduces the heating bill and will always be better than nothing at all, as currently, and all the CO2 released !!
In addition, the more storage there is in free land, the more we will save!
In addition since the solution is in perpetuity, the amortization is certain, with a short time, if we reduce the price of drilling (very possible given what is already used at www.geosec.fr or uretek), since all the other elements already have a reduced price.
It's really the effective solution if you want it and nobody realized it, even the environmentalists !!
