Spending time to cut your utility bills and save energy adds up over time. Energy efficiency is cumulative, do it once and keep saving, and saving. As a former environmental consultant and publisher of environmental magazines, I learned a lot about energy efficiency. One of the favorite things I did was getting something for nothing (over time).
Creating hot water is typically the largest energy user in the home after heating and cooling (HVAC).
The GE hybrid water heater we purchased in 2012 uses about 60% less energy to heat water verses a standard water heater. With the energy efficiency tax break, it paid for itself in less than four years and it continues to save energy. In addition, it is good for the environment.
