How Much Money Do We Spend On Energy At Home?
The average American household spends $1,500 annually on energy billsa number that may go up as much as 50% this year.

  • Almost half of that energy goes to heating and cooling your home.
  • Lighting and appliances represent about a quarter, and
  • Home electronic products like computers, TVs and cell phone chargers take a significant and growing share of what is left
A Light Bulb?
If every household changed a light to an ENERGY STAR one, together we'd save enough energy to light 7 million homes and reduce greenhouse gas emissions equivalent to that of 1 million cars.

What About My Screen Saver?

There is a common misconception that screen savers reduce energy use by monitors; they do not. Automatic switching to sleep mode or manually turning monitors off is always the better energy-saving strategy.

Will On/Off Damages My Computer?

Many people believe that equipment lasts longer if it is never turned off. This incorrect perception carries over from the days of older mainframe computers.

How Much Hot Water Do I Use?
A family of four, each showering for 5 minutes a day, uses 700 gallons of water a week; this is enough for a 3-year supply of drinking water for one person. You can cut that amount in half simply by using low-flow aerating showerheads and faucets.

So What If I Have A Small Water Leak?
Slow leaks from pipes and plumbing fixtures will deplete your precious water storage, causing the pump and the water heater to run and waste energy.
