Around 25 percent of the electricity consumed by American households is used to heat water. Jake's average monthly electricity bill is $186. If Jake installs a solar-powered water heater that does not use any electricity, about how much money will he save on electricity every month?
he would save $186 because instead of using the electricity that he gets from another source that he has to pay for. it makes it so he doesnt have to pay for it at all.
