Your hot water bill can be brought way down with these simple tips. (KABC)

What's the biggest energy expense in your house?

If you guessed heating and cooling, you're right. But there's good news.

The second biggest expense -- heating water for laundry, washing dishes and bathing -- can be brought way down with these simple tips from Consumer Reports.

Nearly 20 percent of water used in the average household comes out of the shower. A standard shower head releases 2.5 gallons of water a minute.

Consumer Reports says that replacing with a low-flow Watersense-approved head that uses two gallons per minute or less can save you 2,900 gallons a year.

And a few habit changes can make a big difference.

First, try a shorter shower.

And quit letting the water run when shaving or brushing your teeth.

After scraping, there is no need to rinse dishes before putting them in the dishwasher. Consumer Reports' experts said you're essentially cleaning them twice, and you could cause the dishwasher's sensors to adjust to a lighter wash and not get them clean.

For best results and energy savings, always run your dishwasher fully loaded.

And consider replacing your old dishwasher. New, energy-efficient models use as little as four gallons per load.

Ninety percent of your clothes washer's energy goes to heating the water. Using warm water instead of hot for your laundry can cut a load's energy use in half. And using cool water will save even more. Consumer Reports tests showed your clothes will still get clean.

"Because energy-efficient washers operate at cooler temperatures, detergents have been reformulated to do a fine job in cool water," Emilio Gonzalez with Consumer Reports said.

And a word about leaks from faucets, shower heads or toilets. One drip per second wastes nearly 1,700 gallons of water a year.

Here's one last tip. To find out if your toilet is leaking, put a few drops of food coloring into the tank. In 10 minutes if there is color in the bowl, you've got a leak, and it's time to fix or replace it.
