Roger Letsch, unbesorgt.de: Das Projekt Desertec wurde 2009 voller Euphorie gestartet. Es sollte die Energieversorgung mit Solarstrom für Europa sichern helfen und dem Erzeugerland hohe Einnahmen sichern. Wie fast immer bei Energiewendeprojekten hat man auch hier versucht politische, öknonomische und Naturgesetze auszuhebeln. Und ist erwartungsgemäß gescheitert. Roger Letsch fasst den Iststand zusammen.

Edgar Ocampo Tellez, energy expert working to develop long termenergy master plan for Mexico: 27,000 wind turbines in Germany provide only 2 % of their primary energy consumption. And like South Australia they rely on their neighbours to keep the lights on.

Bruno Comby, President of Environmentalists for Nuclear: Michael Shellenberger, Founder - President of Environmental Progress: Over the last year, the media have published story after story after story about the declining price of solar panels and wind turbines. People who read these stories are understandably left with the impression that the more solar and wind energy we produce, the lower electricity prices will become. And yet that’s not what’s happening. In fact, it’s the opposite.

Michael Shellenberger, Environmental Progress: • En Allemagne, selon les Amis de la Terre (BUND), de nouvelles éoliennes offshore pourraient « conduire à l’extinction d’espèces individuelles », y compris le marsouin, rare et menacé. • En Amérique du Nord, les populations de chauves-souris migratrices pourraient disparaître, selon les scientifiques, si l’expansion de l’énergie éolienne se poursuit. Une seule ferme solaire californienne, Ivanpah, a nécessité le massacre de centaines de tortues du désert, et tue chaque année 6 000 oiseaux en les brûlant en vol. Vous pensez peut-être que ces impacts sont minimes par rapport à d’autres menaces ? Après tout, les chats domestiques tuent entre un et quatre milliards d’oiseaux par an aux États-Unis.

Fritz Vahrenholt, PhD Chemistry, Chairman, German Wildlife Foundations: You have called the German energy transition a "disaster". How so? Fritz Vahrenholt : First of all, after the tsunami in Japan, the German government decided within a weekend to renounce nuclear energy, which until then had created the base load for German industry. Since then, the government wants to replace this secure energy with fluctuating electricity from sun and wind. Everyone knows that this is not sensible.

John Shanahan, President of Environmentalists for Nuclear - USA: This is a summary of articles about wind and solar technologies without discussion of subsidies posted on this website. It includes comparisons with fossil fuels and nuclear.

Daniel Wetzel, Die Welt: Im ersten globalen Energiewende-Ranking kommt Deutschland nicht mal in Europa unter die Top Ten der Klima-Schützer. Nur gemeinsam mit Frankreich könne Deutschland auf Ökostrom umstellen. Energiewende und Klimaschutz gehören nicht zu den Prioritäten der Regierung. Erreichbar sind ihre 2030er-Klimaziele nur, wenn wir sofort gezwungen werden, jeden Kessel, Ofen, Motor stillzulegen. Völlig illusorisch.

Eric Rosenbloom, writer and science editor: In the U.S., 61.5% of the energy used is “lost,” i.e., only 38.5% of the energy consumed is actually extracted.20 In transmission alone, 7.34% of the electricity generated is lost. There is obviously much that can be improved in what we already have and will continue to live with for quite some time. Many alternative sources of energy, as well as dramatic improvements in the use of current sources, are in development. But wind turbines exist, so they are presented by their manufacturers and managers as the solution. Every effort is made to maintain the illusion that they are in fact a solution when a few simple questions reveal they are not.

Capell Aris, Fellow of the Institute of Engineering and Technology: This paper assesses the cost effectiveness of installing a battery for storage of electricity generated by solar PV rooftop panels. Solar PV can reduce grid import by as much as 40% without need of battery storage. Consumers can shift electric demand to the solar peak production. The low level of winter solar generation in the UK means that battery storage will not be worthwhile.

John Droz is the publisher of "Energy and Environmental Newsletter." A hundred-plus years ago, wind energy was recognized as an antiquated, unreliable and expensive source of energy – and now, after hundreds of billions of wasted tax and consumer dollars, we find that (surprise!) it still is an antiquated, unreliable and expensive source of energy. This is what happens when science is relegated to a back-of-the-bus status. When a major turbine manufacturer calls a catastrophic failure like a blade falling off "component liberation", we know we are in for an adventurous ride in a theme park divorced from reality.
