 Residential energy

The U.S. uses a lot of energy.  While we account for less than five percent of the world's population, we consume about one fourth of the world's energy resources.  Annually, the nation spends about $440 billion a year for energy.ô

Because everything we do requires energy, the subject cannot adequately be addressed in a website of this nature. Therefore, this portion is meant to give a brief overview of only the residential portion of energy, or how we use energy in our homes, apartments, and dorms.  Elsewhere on this website, you can see information about energy use in transportation

As far as our residencies are concerned, we depend on energy for cooking, heating and cooling, and entertainment.  Even something as simple as turning on a light requires energy use. 

Where does this energy come from?  Basically, there are two sources of energy- renewable and nonrenewable.  Renewable sources, such as wind, are constantly being restored or “renewed.”  Across the state, energy companies are researching renewable sources of energy, and trying to use more of them.

However, we obtain a lot of our energy from nonrenewable sources, such as oil, natural gas, and coal.  These fossil fuels took years to create and cannot be replenished over night.  Burning these greenhouse gases may also be contributing to the global climate change.

Therefore, it is important to examine how we use energy in our homes. Looking at the table to the right, you can see that over half of the energy in our homes goes to heating and cooling.  Then almost one fourth of our energy is used for lighting and appliances.

There are many ways we can use less energy and use it more resourcefully.  Please check out the other tabs to the left for tips about conserving energy.  Soon, we also hope to have information available for buying efficient appliances.
