Saving Water Saves Energy… Who knew?


In today’s episode of Hawai‘i: Energized!, we connect the dots on two things that most folks don’t realize go together – saving water and saving energy!

Tannya/Johnny is joined by Hawai‘i Energy’s Shayna & Ramsey, along with special guest Steven Norstrom of the Honolulu Board of Water Supply, to explain how there’s significant energy savings when we all do our part to cut down on our water use.

The fact is, a large amount of energy is needed to treat millions of gallons of water and then pump it to your home or business each day. There are a number of things we can do at home that you might not have thought about in order to save water:

–    Use water saving aerators for bathroom and kitchen sinks, as well as water-saving shower heads.  If you install these, you’ll see your water flow rate drop from 2.2 gallons per minute to about a gallon a minute.

–    Use a shower timer to limit how long you spend under the water. Every minute you trim from your time in the shower saves between 3 to 6 gallons of water. In fact, cutting your daily shower from 12 minutes down to 4 minutes can save you up to $130 a year on your water and electric bills.

–    Place filled bottles in the toilet tank. For those who have older, traditional toilets with a large tank, you can save water by placing a filled glass or plastic bottle in the tank to decrease the amount water that flushes out.

Regarding water conservation, the Honolulu Board of Water Supply offers a $75 rebate for qualified residents who purchase water-efficient appliances, such as ENERGY STAR®-certified washing machines for your clothes.

ENERGY STAR®-certified washing machines use 33% less water than standard models.  Adding one more layer, it takes energy to heat the water in your home. So folks can save money by washing clothes in cold water.

For more information on the rebate program visit, send an email to or call (808) 237-6877.

The bottom line here is every little bit counts. Water is such a precious resource, let’s not waste it. Also know that when we save water we’re also saving energy, which is a win-win all around!
