Increasing your water heater temperature by just 10ÂºF from 130ÂºF to 140ÂºF may increase heat loss resulting in a larger electric bill from $30 to $75 dollars annually. Setting the temperature to 140ÂºF can also increase demand losses resulting in an annual expense of up to $500 dollars.

GPE = mass * g * height. GPE = m*g*h. 1  Elastic-Elastic potential energy is stored when materials stretch or compress. 2  Examples of elastic potential energy include springs, rubber bands, and slingshots. 3  Electric-Electric potential energy is the capacity for doing work based on the object's electric charge.
