on feedback from the policy and the media, at least in the early days, one would have thought the energy concept of the federal government has merely to extend the term of the nuclear power plant facilities. Here this measure is only to win for the realization of the true energy-time approach and funding.
first It is worth noting first that the CDU / CSU-FDP government under Chancellor Angela Merkel has ever presented an energy plan. Because that has been married in the last 20 years no government, because it so given the many controversial energy issues in Germany no one can make law, which also shows again. The government plans remarkable long-term; extends the concept in its plans by 2050, far beyond the period can meet for a government in a democracy commitments. But it still has consequences in the energy sector, which is characterized by specific long-term. Power plants often run for more than half a century, so have the choices of a long day of action in the future. Of course, future governments to change the concept, it is not a plan that is now carried out the next 40 years. You can count on this time and even with an increase of knowledge, which may allow a correction of the climate protection goals, and hope for new technological innovations.
The second basic pattern of Ener2. energy concept is clearly "green". For the first time is a federal government climate protection top priority and declared the intention of the German energy supply to an entirely new basis, because that means that if in the next 40 years some 80% of electricity from CO2-free and half of the should come from renewable energy sources.
form 3 fühlbarste good measure for most people the very broad objectives for the thermal insulation of new buildings and existing buildings. From a technical standpoint, this is very welcome, because the reduction of energy use for space heating has a particularly profound effect. While the ambitious goals can be achieved for the future demand for heating buildings with new buildings even with affordable costs, requires the subsequent isolation of the nearly 20 million existing buildings requires considerable effort. By 2020 the heat demand can be reduced by 20% by 2050 by 80% in order to leave the building sector carbon neutral. The estimates for the costs reach up to 1,000 € per square meter. Even if it's cheaper, would now need to average costs of 1 € per square meter per month, a return on investment for several decades, what is due to uncertainty over the level of energy prices over the next decades, but can not predict accurately. The phrase "checks, the Federal Government, as the tenancy can be changed so that the future offers more incentives for owners to retrofit their homes for energy." Is widely interpreted as an announcement of a partial allocation of expenses to the tenants, through lower energy costs so also benefit from the investment have. Contrary to assumptions in the scenario calculations, which are the basic premise to the federal government has decided to impose the new thermal barrier targets for new buildings and existing buildings formally too big would be the risk that this system of complaints because of an expropriation, with surgery . Kock Whether the objectives of the voluntary, can be realized only by the state-funded and not required measures as planned, at least openly. The debate on the threat of rent increases has already begun.
4th Very also ambitious plans for the expansion of renewable energies, the main burden is to be carried by the wind. This requires the construction of offshore wind farms, since the potential on land is already largely been exhausted, where will the future be made more for less, because to provide by 2020 a slightly smaller number of wind turbines on land, twice the power. By 2030 the offshore wind farms to 25 GWe to be developed to replace the shut down nuclear power plants by then. Have the necessary spare capacity for increasing lately downturns of up to 2 weeks, there is no wind information. Whether the expansion of offshore wind energy sufficient moving forward is, of course not. The financial risks will protect the Federal Government through a special program of KfW. Establishment and maintenance of the systems but also provide new technological challenges. Restrictions may also result from the competition for suitable sites that are reserved for protected areas, roads and military training areas.
internationally but is an issue of growing concern, especially in poor countries.
6th The energy concept assumes that the retention of CO2 will be on the market from the flue gas of coal power stations (CCS) from 2025 and allows the construction of climate-neutral coal-fired power plants. This is in part necessary if one aims for a balanced mix of energy sources, has always been the successful foundation of the German energy supply, because this avoids one-sided mix of technological and economic dependencies. And even with such an ambitious Goal, as the 50% share of renewable energies by 2050, so the other half must be provided as climate-neutral, and without the previously switched-off in any case, nuclear power plants. Second, additional power plant capacity is needed, as it would with the increasing proportion of available renewable energy staggering otherwise the risk occasional bottlenecks in size. Also this approach requires energy that is the construction of many new coal plants, which pushes the time but well accepted issues.
seventh Big goals pursued by the Federal Government of electric vehicles. As soon as the current can be generated largely carbon-neutral, that they also as many vehicles are driven electrically in order to avoid the CO2 emissions from gasoline and diesel engines. By 2020 1 million, his 2050 even 6 million electric vehicles on our roads. This fleet will then be used as storage for electrical energy. This means that parked vehicles must always be connected to the mains, but not just for charging the battery, but even at peak demand shortage in the supply of renewable energies cover by partially unloading to. This of course assumes that the customer is thinking , Get used to the limited range of the electric vehicle of about 150 km, which should at least be enough for a second car, not always fully available.
eighth part of the energy concept and the structure of an intelligent network ("smart grid") and the introduction of smart meters ("smart meter"). The network upgrade is mandatory, since the large capacity of the future, mainly in the north standing wind turbines and the subsequent shutdown of nuclear power plants much more electrical power than must be transported long distances. In addition, the Government expects that will be imported by 2050, up to about 30% of electricity, although it is questionable whether our neighboring countries will be willing to build such a large power plant capacity for us to operate. The expansion of the European network but is definitely a requirement. So we have built a considerable amount of new power lines. The network must be "intelligent" because constantly increasing share of renewable energies to compensate for the fluctuating energy supply must be found. It is expected that one in a system with 50% renewable energy to go to "load management" must. This entails giving time flexible energy consumption in times of abundant supply, washing machine and dryer would be set by remote control after loading into operation, some devices may be turned off by the hour. This is not a doomsday scenario, but surely getting used to and certainly a sign that an "energy revolution", as it heralds the approach of the federal government, not without consequences for any individual and can be left without a change in habits.
9th The energy concept is. significant additional costs. The federal government calls an annual investment requirement of € 20 billion, calls but no number for the federal budget for the various support measures envisaged. Electricity prices will continue to rise, initially due to the large volume of investment, from 2025, the introduction of CO2 capture in coal-fired power plants that will double the power generation costs from coal. For this reason, the authors of the scenario calculations, based on the energy concept, says with great urgency, that such an approach may only be implemented if a legally binding international agreement on climate protection, all other industrial and major emerging countries committed themselves to similar efforts. Otherwise, such a program would be just for the long-term export world champion Germany associated with great competitive disadvantage. The noticeable then in the labor market effects would quickly force a correction of this energy policy, which would be pointless because the world's climate by German unilateralism is not to change.
10th Here's the real reason for the lifetime extension of nuclear power plants. It bridges the time until hopefully international climate change agreement is an accelerated development of renewable energy makes a competitively neutral. Without the continued operation of nuclear power plants would be the CO2 reduction target to reach 40% by 2020, only exceptional extra effort, because the recent savings of approximately 20% would not only doubled in 10 years, but it should also compensate for the additional 15 percentage points be found to save the nuclear power plants in the atmosphere. In addition, the fuel tax and the obligation for operators to promote renewable energy reduces the felt after the financial crisis, debt-overloaded federal budget. The Federal Government has the unpopular measure that is taken for good reasons, it facilitates the start of a very ambitious energy plan, no more and no less. It does not alter that for the first time a federal government gives top priority to climate change and clearly the leading role of renewable energies in future energy supply in Germany says.
