Good morning all.
This time the Gazette comes to you after your vacation or free time because there are no more meetings, conferences, phone calls …. calm for 1 month.
I took back elements for an energy plan. Finally more exactly I compared the arguments. It’s up to you to make up your mind.
The Japanese have once again shown that their safety authorities are not up to the task: steam leak from the turbine of “pressurized water” (1976- Mihama 3- 826 MWe).
The leak had been detected but the operators preferred to attempt a repair without stopping production. The toll is heavy 4 dead and 7 burned.
Obviously the leak is not on the primary therefore a priori no radioactivity and this type of accident can occur on all fuel oil or coal power stations as nuclear. But the question is not there: why (except for reasons of Kwh) continue with a leak on the steam pipes, especially when it persists and of course increases?
This is part of the accident on the gas line: we do not report that we have broken a pipe and it explodes.
Our risk societies cannot afford the rough-and-tumble. And let us not be told once again that “all human endeavors involve risks”. Certainly, but when we know that it is leaking and that we continue all the same, the risk has its back.
This type of accident is obviously possible everywhere, on all nuclear reactors or not. However, trying to repair while running is certainly a breach of the rules for working on a pressurized and high temperature pipeline. If it had been possible to seal it in a few minutes, perhaps we could have postponed the repair but, from the moment the leak persisted and became stronger, there was only one solution, ‘stop.
Y. Bandajewsky is finally out of prison and is in relegation; it is better but it is not yet sufficient. We must continue to write to him to help him and to cheer him up.

In the gadget radius but why not one day efficient. But beware the sea cannot be exploited beyond the possible:
In Greek mythology, Pelamis was the name of a giant sea serpent.
In Scotland, today, the sea monster has become a project of “wave power station”, ie generating electricity by the movement of the waves.
(…) Commercially, the designers of Pelamis foresee its deployment in herds of 30 or 40 units.
Enough to occupy an area of about 1 km 2, perhaps less if the engineers manage to immerse the device at a depth of 50 or 60 meters to save on cable lengths and take advantage of the swell of the depths. The power generated by a single “snake park” (30 MW) could supply 20,000 homes. Twenty zones of this capacity would be enough to cover the electricity needs of the city of Edinburgh and its 450,000 inhabitants.

To be continued …
Over the course of many messages, I found the small text afp on charcoal (See last news). Apart from the fact that France has put itself in the delicate situation of no longer having coal-fired power stations, others have resorted to them and are avoiding monoculture. What do you want we failed to get the message across, so what do we have left?
This text is symptomatic of the fact that we can open up choices if the political will is present. But we can regret that there is never any question of energy savings which must always be put forward if we want to put in place a coherent energy policy, respectful of man and his environment.

Coal still at the heart of energy choices in many European countries
Abandoned in favor of nuclear power in France, in decline in several other countries, coal remains at the heart of energy production in Central and Eastern Europe as well as in Germany, where this mineral was in 2003 at the origin of a quarter of electricity production.
” Coal and lignite power stations will remain the backbone of German electricity production for many years to come ,” Chancellor Gerhard Schroeder assured in November 2003. The share of coal is all the more preponderant in Germany as the country has chosen to give up nuclear power, and that the share of renewable energies is still insufficient.
Ten mines are still active in Germany, compared to 179 in 1945.
The first Spanish electricity operator, Endesa, is also betting on coal, the price of which is considered less volatile than that of gas. It has thus invested 275 million euros to extend the activity of its coal-fired power station in Galicia for twenty years, and plans to open another after 2007.
Coal plays a strategic role in the production of electricity in Poland. , in the Czech Republic, Romania, Bulgaria and Hungary, countries with strong mining traditions. In these five countries combined, the share of coal in electricity production is 65.5%, against 27% in the EU-15.
Thus, in the Czech Republic, despite a restructuring plan implemented in 1992 after the fall of communism, coal will continue to have an important long-term role in the country’s energy supply. According to projections by the Ministry of Industry, it will still represent 30% of primary energy consumption in 2030, against 55% in 1995 and 45% today.
In Slovakia, Slovenia and the three Baltic countries, the absence of mines has historically led to favoring other sources of energy.
In constant decline compared to natural gas, with 32% of electricity production, coal is the second energy source in Great Britain, behind gas (38%) and ahead of nuclear (23%). Sixteen mines are still in operation, but the Commerce Ministry estimates that most of them will likely be exhausted in ten years. In Portugal, coal represents 30% of energy production, behind hydraulics (34%), but is steadily declining compared to natural gas (16%).
Most of the countries where coal still plays an important role in electricity production now favor importation, the ore being too expensive to extract at home. This is the case of Croatia, which ceased production in 2000 when about half of the country’s electricity is produced from coal, as well as Great Britain which brings the ore from the United States. United, Russia, Colombia and South Africa.
Conversely, in Italy, where the abandonment of nuclear power was adopted by referendum in 1987, the idea is to develop domestic production of coal, an ore which only contributes 9% to production.
national energy. A project is under study to increase production at the country’s only mine, in Sardinia, from 400,000 tonnes to one million tonnes per year.
Coal only represents a very small part of energy consumption in France (4%, as a back-up), as well as in Belgium and the Netherlands. In the latter country, the authorities have chosen natural gas as a priority and are developing “clean” energies, while in Austria, hydropower takes priority at 70%.
