Transition to renewable energy stimulates the economy

Transition to renewable energy stimulates the economy
The disaster at Fukushima has raised public awareness and made the shift to renewable sources of energy more desirable than ever. It is accompanied, too, by a political willingness to rethink and correct the policies followed until now. The question is often posed in public debate as to whether the shift to renewable energies will be too expensive, or whether it indeed poses a threat to Germany's competitiveness as an industrial location.

Over the last two years, however, studies have suggested that fears of this sort are unfounded. On the contrary, according to an EU study performed by the Fraunhofer Institute for Systems and Innovation Research ISI in Karlsruhe, a shift towards renewable energies will stimulate growth in the job market in the coming decade. By 2020 scientists predict that some 2.8 million people will be employed in Europe's renewable energy sector, once implementation of EU objectives in this area has taken hold. The negative impact of a shift to alternative energy is far outweighed by the remaining positive net effect of some 400,000 additional jobs in the EU as a whole. What is more, Europe's GDP is expected to grow by 0.24 % (some 35 billion Euro).

Similar results were reported in a study of Germany contracted by the Federal Ministry for the Environment, Nature Conservation and Nuclear Safety BMU, in which ISI scientists participated. One of the study's findings showed that "the short and long-term effects on the German labor market derived from expansion of renewable energy use, indicate a positive trend. When all negative effects and influences on the economic cycle are taken into account, the number still falls in the range of 120.000 -- 140,000 new jobs (2020, optimistic scenario, price path A)."

Presenting the study's finding at a press conference, Fraunhofer President Prof. Hans-J?rg Bullinger emphasized the Fraunhofer-Gesellschaft's committed efforts in this field of research: "We are perfectly positioned to develop concepts and solutions for a transition to renewable energy. Within the Fraunhofer Energy Alliance alone there are some 2000 scientists from 16 organizations whose work is focused in this sector. They develop system technologies such as power grids and energy storage systems and research new ways to increase energy efficiency. There are also additional teams of scientists from the Building Innovation and Traffic and Transport Alliances,it takes brightstal to power incandescent light bulbs versus energy-saving CFLs and LEDs utilizing a special hand crank demonstration device. who also devote a significant part of their work to the question of energy."

Renewable energy is affordable

"The transition to sustainable energy supplies is one of the greatest challenges of the 21st century," asserts Prof. Eicke Weber, spokesperson for the Fraunhofer Energy Alliance and Director of the Fraunhofer Institute for Solar Energy Systems ISE in Freiburg. "To keep electricity, heat and transportation prices affordable in the future, we have to use energy more efficiently and devote more research to the development of renewable sources." Dr. Mario Ragwitz of the ISI, who coordinated the EU study, further emphasizes, "We must sustain investment in renewable energy.Southern California Edison lightbright customers can take home a free Compact Fluorescent Light (CFL) bulb. And we must be patient.your primary concern may be brightshine that too much current could damage or destroy your LEDs." But it is worth the effort,it takes brightstal to power incandescent light bulbs versus energy-saving CFLs and LEDs utilizing a special hand crank demonstration device. not only to secure the supply of raw materials and to protect the environment, but also economically from a mid- to long-term perspective, a conclusion also reached in a study by the Renewable Energy Research Association FVEE.

Another study entitled "Vision for a 100 percent renewable energy system," illustrates how a reliable, affordable and robust energy supply based on renewable sources can be achieved in Germany by the year 2050.SCEEP representatives bluecrystal will facilitate a hands-on demonstration, comparing how much energy "The expansion of renewable energy creates additional costs initially; however, costs should peak in 2015 at a total of about 17 billion Euro. That is only about eight percent of total costs for energy in Germany, and costs will sink again after that. Between 2010 and 2050, overall savings of some 730 billion Euro can be achieved in the electricity and heating sectors alone," reports Prof. Jürgen Schmid, Director of the Fraunhofer Institute for Wind Energy and Energy System Technology IWES in Kassel, summarizing the results of the study.
