China Finds Something Strange in Sample Retrieved From Moon
ca.news.yahoo.com
Lunar Graphene Chinese scientists have made an unusual discovery while analyzing the sample Chang'e-5 collected from the Moon's surface in December 2020. They found naturally occurring "few-layer graphene" for the first time, as state-run news agency Global Times reports, which could have major implications for our plans to make use of local resources once on […]

      bad for the environment

      A short summary:

      Offshore wind farms have a big impact on underwater pollution. From their construction to their deployment, offshore wind farms, with their turbines and metallic foundations, generate noise and vibrations below the sea surface (called “anthropogenic noise” because it is unnatural and human-made) that disturb marine life and flora, especially for the underwater mammals that rely on sound (like echolocation or vocalization) to survive in the ocean.

      But here's a full report on environmental impacts where it is all rated "moderate" severe: https://www.boem.gov/sites/default/files/documents/renewable-energy/state-activities/Revolution_Wind_DEIS__Vol1and2_508_compressed.pdf

      impossible to recycle

      The blades are impossible to recycle.

      In the US alone, some 8,000 blades were pulled down in 2021. Most blades were landfilled because there wasn’t much else that could be done with them.

      By 2030, it is estimated that more than 52,000 tons of wind turbine blades will need to be recycled each year in Europe alone.

      less efficient than the alternative (nuclear)

      I already posted a link to the MIT website where they say you need around 900 wind turbines to match the power output of an average/medium-sized nuclear power plant.
