All calculations are rough estimates only. The Annual Energy costs for your appliances shown above do not reflect your actual home energy costs. They are not to be used as a representation of what your specific costs might be as a result of the implementation of any or all of the energy savings measures. Your actual energy bill will be different from these estimates because this tool does not use your actual billing history and energy savings may be affected by factors not considered by the Home Energy Calculator.
