Electricity from shale gas vs. coal: Lifetime toxic releases from coal much higher

ANN ARBOR — Despite widespread concern about potential human health impacts from hydraulic fracturing, the lifetime toxic chemical releases associated with coal-generated electricity are 10 to 100 times greater than those from electricity generated with natural gas obtained via fracking, according to a new University of Michigan study.

Windparks erzeugen lange Wirbelschleppen

Forschungsteam misst erstmals direkt das großräumige Windfeld hinter Offshore-Windparks in der Deutschen Bucht

Ein Forschungsverbund hat erstmals großräumige Nachläufe hinter Windparks in der Nordsee mit einem Forschungsflugzeug nachgewiesen und vermessen. Die sogenannten Nachläufe oder Wirbelschleppen hinter Offshore-Windparks entstehen, weil diese den Wind als Hindernis bremsen und ihm Energie entziehen. (more…)
