This task and Zero Waste Day are the most difficult ones. I live in a flat in Madrid that I rent, so it's challenging to save energy in a place where the washing machine is over 10 years old, there are no dishwashers, so needs to be cleaned manually. The positive part is that I live alone, so there aren't many stuff to clean, and the idea is to group many things (clothes, plates, cookware, etc.). I've tried to convince my landlord to change the washing machine, but it's not possible. I check my energy and water bills and follow up to maintain and reduce consumption. Is the least I can do.
