In 2016, as told by the U.S. Energy Information Administration (EIA), the energy produced in the United States was about equal to the amount consumed by residential and commercial sectors. Per person, total U.S. energy consumption was approximately 301 million Btus., although energy consumption varies depending on the climate where we live and the types and numbers of energy consuming devices we use (EIA, 2016). For example, residents of the Southwest states such as Arizona, California and New Mexico, often use the most energy to cool their homes during the summer.
In recent years, however, using energy more efficiently has become an important priority for residents, businesses, and governmental agencies alike. In fact, many states have adopted policies to encourage energy efficiency; Washington included. Homeowners are making energy efficient improvements by installing ENERGY STAR certified equipment and insulation with high R-values. New technologies designed for energy savings are also beginning to emerge. Here are just two of the emerging technologies we can look forward to soon, but in the meantime, there are many things you can do save energy.
First there were smartphones, then came smart speakers, and now smart windows. Researchers at Princeton University have developed a futuristic smart window that has the potential to reduce energy costs by up to 40 percent. According to Science Daily, “the self-powered smart window controls the amount of visible light and infrared heat into the building, while the new type of solar cell uses near-UV light to power the window.” The technology promises to be inexpensive and easy to apply to existing windows. Researchers hope that once installed, users will be able to control the amount of sunlight entering their homes, and thereby improving energy efficiency, comfort and privacy via an app.
R25 Insulating Materials
Insulation can greatly reduce your heating and cooling costs. Other advantages include absorbing emitted sounds and controlling humidity. The Oak Ridge National Laboratory (ORNL) and Building Technologies Office (BTO) is developing two-inch thick polyisocyanurate board insulation with modified atmosphere insulation (MAI) cores that have an R-value of 25 (R12/inch). According to the U.S. Department of Energy, “these panels have the potential to pay for themselves from energy savings within 10 years, while saving more than one percent of all of the energy used in the U.S. today.” This insulation would be beneficial for both residential and commercial applications.
