Dunny ice

The Energy and Climate Week Show: While in the Arctic of Icefall continues and energy companies hinder the expansion of wind energy use, the Federal Environment Minister vibrates to the Furspecher of Kohlelobby

The combustion of coal is worldwide by far the big source of greenhouse gases. This is not different in this country: In power plants with an efficiency usually less than 40 percent is covered from the burning of stone and lignite almost half of the power consumption, which causes around 42 percent of German CO2 emissions.

Then you should mean that Federal Environment Minister Sigmar Gabriel is at the very beginning when it comes to preventing new power plant buildings, as you are currently doing (HTTP: // mercury.Wordpress.com / coal /) are in conversation. But far. According to an agency, he threw the opponents of new coal-fired power plants to demand nuclear power. In addition to the coal-fired power plants already under construction, ten more feasible, without harming the climate protection goals of the Federal Government.

The question is, however, whether they are sufficient. Also with the contested reduction of emissions by 40 percent against the 1990 degree level, the German per capita emissions with 7.3 tonnes of CO2 per year (or. 8.8 tons, if considered the other greenhouse gases) far above the two tons per capita and year, which the climate system is currently contracted. Two tons of CO2 per earth dweller and year will be included by Oceans and Biosphare. This amount thus does not contribute to the increase in the atmospheric CO2 concentration.

Poleitheater

Gabriel’s exercises fell in the context of the Polittheater, which is currently under the power supply. Lobbyists of the coarse energy companies have been providing the media for a few weeks and again with wordwalent warnings before the "current prere", which threatens 2020, sometimes in 2012. Also Minister of Economics Michael Glos and the German Energy Agency under him Dena is in this horn.

The probably decisive motive is the interest of the striking companies to extend the maturities of nuclear power plants. After all, the ages are among them, as it has been depreciated, pure money printing machines, with which 200 to 400 million euros a year leaving. Anyway, the Federal Environment Agency (UBA) has responded to the current campaign with a small study. A "current prere" is not to be expected if the following three goals were realized:

  1. Reducing the gross electricity consumption by eleven percent by the year 2020 against 2005,
  2. Expansion of power-warm coupling (CHP), mainly on natural gas based to double the proportion of CHP stream to 25% by the year 2020 and
  3. Expansion of renewable energies to just under 30% of power generation by 2020.

The office otherwise ames that there will be a power plant construction, but not necessarily in the fracture:

The question of which power plant type is built, in the opinion of the UBA, is influenced by the European emissions trading. The shortage and auction of the certificates as well as rising fuel prices and the increase in investment costs for power plant construction – counter-consuming electricity prices are amed – for this result that producing condensation coal-fired power plants (hard coal or lignite) – in contrast to the power-warm coupling and renewable energies – uneconomical will. This was allowed to act from the self-interest of investors towards low-emission power generation and economical electricity use.

Grunes light in the US

Beyond the Atlantic, in the US, romp very similar conflicts of interest. Also there many electricity companies want to build new coal-fired power plants, whereas burger defend. But there are also the trail of renewable energy sources. Through the last week a breath, according to which the Senate passed a law that demands the tax relief for wind and solar systems.

Now only the Reprosign House has to agree, then the continuation of the boom is of wind CO. nothing in the way. In 2007, wind facilities with a total capacity of 5 were in the USA.244 megawatts have been installed, the World Watch Institute reports in Washington. Some suggests that it can continue at this tempo.

Worldwide boom

Also elsewhere, the market continues to expand. According to the data of the Young Deputy Status Report Renewable Energies 2007 of the World Watch Institute, 71 billion US dollars were put into new wind chairs, solar cells and similar. Almost 50 percent accounted for wind energy, 30 percent on photovoltaic systems. Unlast, the market has come out of his niche-eating and became a torque of investment bankers and fund managers who are attracted by the enormous growth rates: the capacities of the world-wide wind farms grew by 28 percent to 95 gigawatts.

Photovoltaic and solar thermal are offered less for their mostly small-scale applications less, but here the rates are considerable. The solar power capacity grew by 50 percent in 2006 and 2007, which of warming from the sun for heating and hot water by 19 percent. With worldwide 7.7 gigawatt capacity is the contribution of photovoltaics for power supply but still tiny. But should the current growth pace be maintained for a few more years, then the rapidness could change.

While otherwise it crunches in the building of the global economy and sweat the bankers of blood and water, the manufacturers of solar systems, wind rackets and similar from crisis is nothing to traces. Accordingly, the quotations of many companies have now climbed high. The 140-worldwide stock corporations in the industry bring it together to a market capitalization of Uber $ 100 billion in US dollars. However, this is some share whose value is just justified when in the corresponding company in the obsumption is really all round. The demand programs, which are now in 66 states, including 23 developing countries, were allowed to provide for excellent conditions in the coming years.

Dispute over the networks

However, it looks less pleasing with the German offshore program, for which the starting signal was announced by the author of these lines several times ahead of TelePolis. The Baltic Sea newspaper reports from a sticker of the expansion in front of the custodians. By 2030, according to the planning of the Federal Government 25.000 mw to performance in front of the custs installed. There, the wind gears are favorable than on land, so that a higher yield per system is to be expected.

Planned wind farms and Natzbindungen in the North Sea. The dashed line marks the wing water, the dark blue flat the lovable economic zone (AWZ). The AWZ is no longer belonging to the territory of the Kustenanrarer, but they have as the name already says, cherical rights of use. The small green flat top right before the Danish Kuste is an already running wind farm. The ocher-colored flat and lines already mark approved parks and cables. Red flat designation parks still in approval procedures are dark blue lines planned cables . Graphic: Dena

But the construction is complicated: special vessels and other equipment is scarce, says the business carrier of the Federal Year of Wind Energy, Ralf Bishop, in the sheet. In addition, exploding commodity prices had the cost within a few years by 30 to 50 percent in the high driven. Bishop towards the Baltic Sea newspaper: "If not energetically counteracted, the market 2010 is dead."

Most headaches, however, the windmullers prepare the power supply. The energy industry obliges the coarse network operators – Vattenfall in Mecklenburg-Vorpommern, E.On in Schleswig-Holstein and Lower Saxony – for cable construction from the wind farms to the Kuste and the corresponding expansion of the networks. But one is decorated. The state could not force the corporations at unprecedented investments, beginning Marz the Peiner General Zeitung quoted unnamed voices from the industry. May be that you want to play a little time on time, because the rule is only valid for wind farms, with their construction up to 31. December 2011 started.

Planned wind farms before the Baltic Sea Custody. Early as above. On the two parks in front of the car, which after the present stand both for a lanan binding should be read, you can read quite well, how little coordinates so far has been done in the question of grid connection. Graphic: Dena

An immediate reason for the consolidated growing was a Vattenfall study, which had aroused unpleasant: Investments in the network connection of the Wind farm "Baltic 1" before the Darb in Mecklenburg were only a return of three percent for the Group. The keeping the company – Vattenfall boss Lars Goran Josefsson is UBERGER’s climate counselor of the Chancellor – apparently for unreasonable. According to DENA, expenditures for high-sea cabulants amount to about one third of the total project costs. By 2015, in the North and Baltic Sea, an investment requirement of 2.6 billion euros for the mains connection is calculated.

Another bottleneck is the networks on land that transport the electricity from the low-consumed custodian regions into the metropolitan centers in the south. Be a long time is known that the high voltage network must be required by about 850 kilometers. The situation was encouraged in addition to the fact that a whole series of coal-fired power plants were planned at the custo, which were widely produced by the regional needs electricity (plane, among others, for Emden, Wilhelmshaven, Stade, Brunsbuttel, Hamburg and Lubmin). Schleswig-Holstein’s Minister of Economic Minister Dietrich Austermann means these should be built above all to cover the supply of wind turbines at lulls (see also coal at any price). In the trap, coal and wind have no competition to make transfer capacity. In fact, however, the coal-fired power plants for the operators are correctly profitable if they are about 6.000 from 8760 hours a year.

So far, the network operators with the expansion can be plenty of time, so that the Baltic Sea newspaper is already speculated, it could be with the acquaintances (E.ON) and suspected (Vattenfall) sighted sales. Whoever wasted the net anyway, will hardly take big sums in hand. Like that: Ulf Gerder from the Federal Association Wind Energy complains in the interview with the same newspaper that everything could go much faster. MUSE MUSE instead of the unloaded in the burgers and therefore heavily enforceable overland lines just make ground cable. A variant that also requires the Schleswig-Holstein state parliament for a long time, but at E.On and Vattenfall is insisting that this is too expensive.

Meereis to Dunn

Meanwhile, in the Arctic, the sea ice has exceeded its freely maximum and starts to tauen. As reported several times, the ice cover was significantly coarse than in the Vorwinter, which was followed in the summer of 2007 a record minimum. However, in winter 2007/2008, the ice covering on the Arctic Ocean and its neighborhoods was even smaller than the long-term average. Ice deficiency was mainly in the Baltic Sea, in the Barents Sea between Spitzbergen and the northeastern custo and in the Gronlandsee.

Dunny ice

Age of the Arctic sea in years. The illustration clearly shows that the flat alter and thus thicker ice from 2007 is further reduced to 2008. About 70 percent of the ice is built in a year old, which has been formed in the resuming winter. In 1985, this value had still been below 40 percent and has since never been continuous since.

In any case, the researchers of the US National Snow and ICE Data Center in Boulder, Colorado, no reason to get the all-clear: More than ever before the sea ice is from Dunnem, built-in ice this year, which easily disappears this summer again could. Currently, 72 percent of the Arctic basin is covered with the particularly sensitive ice. In Marz 2007, it had been 59 percent, which had been one of the highest values until then. Only about 30 percent of the one-year ice is used for usual ice cream. Or in other words:

Also this summer, the sea ice will be back with great chance. Rough parts of the Polarmeer could be created for months from the sun, and the devil circulation of less ice and warm water continued to take his course.
