In an effort to reduce our electricity consumption and carbon usage, run builds once a week on a Monday morning rather than every morning.
2am to 6am seems best in terms of the renewable electricity mix based on https://electricityinfo.org/fuel-mix-last-24-hours/ and the forecast for London in https://electricityinfo.org/carbon-intensity-by-region/
