Today's challenge is up:
Only use your washing machine when you have a full load, and run it on cold whenever possible. Run at maximum spin to reduce drying time and avoid using a tumble drier. A typical washing machine uses 90% of its energy to heat the water. Generally, cold water gets your clothes just as clean and saves about 2 pounds of CO2 per load.
Until tomorrow ...
