The Energy and Climate Week Show: From Zive emissions, Gabriel’s failure, high-flying energy and athiopia climate-friendly development

For a variety of a good news in terms of climate protection: In the European Union, the emissions of the greenhouse gas carbon dioxide (CO2) in the past year are raised at least fun percent.

This is apparent from a report of the EU statistical persons. The information is only a premier estimate based on the monthly energy statistics.

Accordingly, they do not affect all greenhouse gases, but only the CO2 released when burning fossil energy carrier. In Germany, the approximately 80 percent of the greenhouse gases, if they are weighted according to their climate efficiency and expressed in so-called CO2-aquivalents. The emission data for all EU states and greenhouse gases until 2012 can be found here.

The most strongest was the percentage racy in Slovakia with -14.1 percent and in Danemark with -10.7 percent. There, wind energy had a share of 39.1 percent in the power supply last year. In Germany, the ruckle with -3.1 percent fell very moderate.

In the Netherlands, however, the ruckle was -6.9 percent, writes the English speaking newspaper NL Times.

However, thanks to the liberalization of the electricity market, the neighboring land imports large amounts of electricity from the RWE lignite power plants in the Rhineland. A good example of this that the market faults by no means always show meaningful results.

Before the largest electricity trade has been extended so much, the Netherlands has largely supplied with electricity, among other things, from gas power plants, which were now displaced by the cheap lignite. RWE itself had bought some of them in the context of his expansion to the neighboring country and has been shut down now.

Anyway, it remains to be seen whether the last-year-old racy of emissions in the EU was sustainable. Fluctuations around a few percent up and down are normal in Europe and are affected by the weather and their influence on the demand for heating energy.

In the Netherlands, the sheet writes, emissions in the first quarter, according to the local statisticians, are already pushed up again. Debt were lower winter temperatures also strong economic activities.

Gabriel can not prevail

In order to really sustainably reduce emissions, coal-fired power plants had to be made auber service, which in this country without further benefits.

Finally, Germany has exported the production of approximately seven coal-fired power plants in recent years alone alone. In 2013, Netto-StromExport was around 32 billion kilowatt hours around 32 billion hours around 30 and 2014.

This year, it was already 23.2 billion kilowatt hours. And how the example shows Netherlands, it usually does not matter that the need inland could not be covered. Rather, German coal-fired power plants impregnate competitors on the respective market.

This could be prevented with different means if the political will to be a bit more climate protection. For example, the CO2 certificates had to be more expensive that the power plant operators have to show.

This had reduced its competitive advantage, but the Federal Government has ensured that the corresponding European emissions trading system is only reformed from 2019. Whether the changes will be effective at least then remains to be seen.

Another possibility is a special CO2 levy for the old and above-average inefficient coal-fired power plants, as they were emerging in the Federal Ministry of Economics. But it’s bad for this.

Vice-Chancellor Sigmar Gabriel (SPD) can not prevail with the idea of his house right in the coalition. The delivery is before failure, reported the Handelsblatt last week. From the Union and from some SPD-ruled federal stations come too much resistance.

As maybe Chancellor Merkel (CDU) is silent for important confrontation and sees how party friends and coalition partners dismantle each other in the openness. Meanwhile, she continues to celebrate from the media as a climate dish. Rhong politics flat.

Energy

For wind turbines one thinks of usual tower, on which three-flattened rotors turn. Maybe on hectic small plants, like this in Berlin or this here on Heligoland.

However, there are still completely different ways to convert the motion energy to electric power in the wind.

At the technical university in the Dutch Delft, you have been researching the use of steering dragons for several years. However, the Delft Group is not the only one who pursues such ideas.

Since yesterday’s Monday, a specialist conference with around 100 participants is true at the Delfter TU, as the magazine renewable energies reports.

The preferences of the so-called high wind turbines consist of their high flexibility – if they are not a rail-bound, as the German Start Up NTS plans – the much lower cost of materials and in the fact that the wind can be used in high over 200 meters.

There he blows more inventory and more forceful than in land. In addition to steering dragons, such as the Delfter and other form also use German Enerkite GmbH, there are also static flights where rotors are attached with generators, as they developed the Google-based company Markani.

The Federal Association Hohenwinden Energy speaks of 30 companies that work mainly in Western Europe and North America on various projects.

Marktreif is none of the concepts. One of the problems is the automation of the operation. If they have been resolved, then appropriate plants could probably – industrial mass production provided – providing electricity with growing costs under funf cents per kilowatt hour.

That’s how it hopes the land of NTS. Enerkite talks about it, "Automated flying tufts", want to create, "which use the steady wind above the sheet peaks today’s wind ratings and deliver with 90% less material to double energy yield in case of halved electricity stations."

Less Burocracy

A concern will definitely do not have any users of the Hohenwinds in the future: they do not have to build any of their systems, nor complicated heavy duty transportation. You easily drive your mobile systems to suitable sites.

For modern wind turbines, however, numerous special transports are necessary and the Turmhohe stobs to its limits, because the diameter of the segments is limited by the full high of the highway brood.

MODULAR SYSTEMS Like the wooden palm of Timbertower offered remedies.

But they make first careful steps on the market and even a wooden tower will not get along without the corresponding complicated transport long rotor blatter and heavy generators and gondolas. This was pleased to simplify the Federal Association Wind Energy.

In a press release sent on Monday, the association indicates the considerable burial and technical effort, which currently around 35.Require 000 special transport.

He is aware of the art not only the police, but also private companies to secure the transports that are replaced individually by collection authorizations and the procedures and regulations are standardized across the land borders.

Model Athiopia

In the run-up to this-year UN climate conference, the states gradually range from self-commitments in which they describe their national climate protection goals they want to achieve in the next decade.

It’s still sluggish, but after all, a round Funtel has already submitted his documents in the Secretariat of the UN Climate Framework Convention in Bonn.

The youngest explanation comes from Athiopia. The country undertakes to restrict its greenhouse gas emissions to 145 million tonnes by 2030. Although these were only fun millions of tons less than being emitted, but opposite one "Keep it up" An enormous progress.

If, on the other hand, the country was further developing his economy as previously as before and technologically take an example of the industrialized countries, then 400 million tonnes of CO2 aquivalents were blown into the air in 2030.

So scheduled is a relative reduction of 64 percent. (For comparison: Converted to the population, emissions in Athiopia 2010 were 1.7 and in Germany 11.6 tonnes per capita and year.To)

The country at the Horn of Africa currently has a little more than 94 million inhabitants. The population grew by average 2.9 percent in the past two decades, for the period 2012 to 2030, the Fischer Welthalmanach expects an average rate of 2.3 percent.

The economy is still growing faster. In recent years, the increase was usually between seven and over ten percent. So the land seems to be slowly out of poverty, but certainly has a long way to go.

According to Fischer Weltalmanach was the gross national income in 2013 at 470 US dollars per capita. In 2003 it was only 90 US dollars per capita and year. (For comparison: 2013 were $ 7030 in Bulgaria, in China 6560 and $ 46100 per capita in Germany.To)

The Athiopian commitment is subject to the subject that in November at the UN Climate Conference in Paris "Ambitious multilateral contract is completed, which allows Athiopia to get international support and investment stimulates".

The occasion of emissions should rest on four pillars: modernization of agriculture, protection of the Walder, generation of electricity using renewable energy carrier and the development of transport infrastructure and the city with modern, energy-efficient technology.

Among other things, this day is inaugurated in Addis Ababa an electric light railway. The railway network should also be expanded. On the top of the blue nil, the further – controversial – dam under construction, which will have six gigawatts.

This corresponds to about seven modern coal-fired power plants from the rough, as they were built last in this country. The country already has a number of wind farms.

Should Athiopia have success and, in fact, can hold its greenhouse gas emissions in the fence as described above, then it became all elaborations of Germany, where you still see themselves as a pioneer, leave far behind.

The Athiopical emissions (CO2 and other greenhouse gases) were at 1.2 tonnes per capita and year, if the population will probably grow 126 million people and prosperity on the level of the poor EU members.

In Germany, on the other hand, they were – constant population, which ames the absence of the rough euro crash and the achievement of the goals formulated by the Federal Government – still at 6.7 to 7 tonnes per capita and year.
