Energiewende doesn’t translate as “energy mess”

This year, US Senator Lamar Alexander has lashed out against Germany as an example of where the United States should not go. The desperate attempt to reframe the Energiewende as an “energy mess” shows what the real threat is: Germany is poised to prove that a low-carbon future without nuclear is the best option for a thriving industrial country. read more »

Bladeless Wind Turbine — Reality Check

Bladeless wind turbines are back in the news although the technology has no potential, as tests decades ago demonstrated. But the story does show that both journalists and the public need stories about breakthroughs, so we will continue to get such reports even though we already have the technologies we need. A guest post from Clean Technica. read more »

German Medical Association looks into health effects of wind power

Reports have turned up in Australia and France about a GMA document from the Association’s recent conference. The text allegedly claims that German doctors are concerned about the health impacts of wind power. So why aren’t German media covering the news? read more »

Germany proving skeptics wrong on renewables

With more than a quarter of the country’s electricity now coming from renewable sources, Germany’s energy transition – or Energiewende – is delivering reliable electricity, reducing emissions, and even decreasing overall costs. To see that, all we need to do is look at the data. read more »

A (silent) revolution in the wind sector

Over the past few years, a dramatic shift has taken place in the type of wind turbine installed, as the US market shows. The focus is clearly on raising capacity factors by increasing tower height and rotor blade length relative to generator output. Despite already high capacity factors exceeding 40 percent, Bernard Chabot says 60 percent is within reach. read more »

World's oldest operating wind turbine turns 40

If you can make it up to Denmark on May 30, you can take part in a special birthday. Tvindkraft, a 1 MW Turbine built as a school project, will be turning 40. The machine was built right under the noses of heavily funded R&D projects by aerospace engineers. Their turbines were scrapped after only a few years. As guest author Paul Gipe explains, this one keeps turning. read more »

Are the poor paying for the rich in the Energiewende?

A new study in Germany looks into the social impact of the country’s energy transition – not only how much is being paid, but whether specifically low-income families are subsidizing green pet projects for the rich. read more »

Silent wind revolution in Germany

Bernard Chabot is back today with an impressive overview of a trend in the German wind sector. The focus is increasingly on smoothing out power production, not increasing peak capacity. And it is happening without specific policy incentives. read more »

The right way to integrate solar + storage on the grid

Around the world, the discussion about storing solar power focuses on on-site consumption. But that approach does not do what the grid needs. Today, US utility expert James White presents a proposal to fix that problem. read more »
