You could install low-flow shower heads, take shorter showers, or both. And while you're washing up, cut back a bit on the hot water. Clear, cool water is better for your skin anyway, Bain said.
Cold water is also fine for most laundry, and is more economical. And if you're going to wash laundry, Bain said, wait until you need to do a full load. Washing machines take 15-40 gallons of water per load, depending on the machine. Newer machines use less, but with a new machine and a small load, it still takes the equivalent of 15 one gallon containers of water to do the job.
How does a full load help? Bain feels using 120 pounds of fresh water to clean a pair of socks may not be the wisest use of resources.
