Now that it’s the middle of summer, Californians are taking advantage of their pools. What many homeowners might not know is that keeping their pool clean via pool pump could be a lot cheaper. If you still have an old single- or dual-speed pool pump and are tracking your energy consumption, you likely know that your single-speed pump is a giant energy hog.

One of the biggest drivers of the rooftop solar trend has been net energy metering (NEM). NEM is an agreement between a homeowner and the local electric utility. Under NEM, homeowners generating excess electricity from their rooftop solar systems can send it back to the electric utility, which credits the customer’s bill. NEM benefits homeowners because the bill credits increase the return on their rooftop solar investment. Depending on how the arrangement works, it can also benefit utilities, who can lock in low rates for power that they don’t have to generate elsewhere.
