The sun is shining, the wind is blowing a gale, and just 2.4% of British electricity is coming from fossil fuels. See the live data at https://grid.iamkate.com.
@katemorley As the amount of battery storage and return increases, that might become a figure of interest? I don't know how it would best be represented. Possibly no more than a green/blue meter as on my car, for saving Vs using, but perhaps even another ring reflecting source.
#electricity I do like your existing meters.
