Researchers at Fraunhofer IFAM have developed a casting technique that can be used to produce lightweight aluminum windings with a higher groove fill factor to replace copper windings in electric motors. To show this in a direct comparison, the Fraunhofer team used 250W commercial pedelec motors. © Fraunhofer IFAM.

Extracting energy from the wind causes climatic impacts that are small compared to current projections of 21 st century warming, but large compared to the effect of reducing US electricity emissions to zero with solar. They find that large-scale wind power generation would warm the Continental United States 0.24 degrees Celsius.

This year has brought a significant shift in the generating cost comparison between renewable energy and fossil fuels, according to detailed analysis by technology and region, published this week by Bloomberg New Energy Finance. In the US, coal and gas are still cheaper, at $65 per MWh, against onshore wind at $80 and PV at $107.

For comparison: This is equivalent to the output of a 700-megawatt offshore wind farm with coupled electrolyzers. The feedstock pellets from the pre-treatment plant will then be converted into hydrogen in a second RWE plant which the company is to build at the Chemelot industrial park in Limburg.

The key enabler for the dual-rotor concept is a new distributed winding concept with a slot-filling factor above 80%. DeepDrive says that their motor will have less than 30% of the cost per N·m in comparison to current state-of-the-art motors.

Green steel will be a critical raw material for developing renewable energy infrastructure, such as wind turbines, as well as in segments such as construction, the automotive industry, and consumer goods. Inkoo power plant. Fortum’s 1,000-megawatt Inkoo power plant was commissioned during 1974–1978. The now-demolished Inkoo coal plant.
