10. Use water and electricity more efficiently
Conserving water protects from future water shortages and saves energy in the process of transporting it to you. There are many other reasons to protect water supplies, so it’s worth assessing your own use.
Are you filling up more jugs of water for customers in advance than you actually need? Is your dishwasher (if using) or washing machine Energy Star-qualified? Can you wash more things in the sink, using less water, than the dishwasher? Is your toilet using lots of water and can be replaced with a better flushing mechanism?
With electricity, switch off as many things as you can at night so there are no unnecessary lights or machines on standby overnight. Use sensors for the lights in the toilet, and check if your fridges, freezers and brewing equipment are energy-efficient too. Avoid tumble-drying which uses a lot of energy; instead, hang out textiles to dry naturally.
If you rely on high-energy equipment, set some rules about when to have it off or at least on standby.
