Energy costs seem to be on a constant rise. Part of it is because of inflation, but in part it is due to the depletion of natural resources which are used to generate the energy.
With that in mind, it is in your best interest to keep an eye on energy spending in your home and how it can be controlled.
For example, if you have a lot of old fashioned incandescent bulbs in your home, you will find that they waste a lot of energy. Only about 5% of the energy those light bulbs draw is being converted into light while the rest is wasted as heat. If you install LED or CFL bulbs in their place, you will see significant energy savings.
Having a smart or programmable thermostat will also let you control how much of your energy is used for heating and cooling. You can save a significant amount of money by turning off your air conditioning or heat while you are out of the house or sleeping.
