Many people worry that installing a sprinkler system will cause their electricity bills to skyrocket. However, studies have shown that properly installed and maintained sprinkler systems actually use very little electricity. In fact, they use less than running a coffee pot or charging your cell phone. nnOf course, the amount of electricity a sprinkler system uses will depend on the size of your yard and how often you use it. But even if you have a large yard and water every day, you can expect your sprinkler system to use less than 2% of your total electricity usage. So if you're worried about high electricity bills, a sprinkler system is not likely to be the culprit.
