During the U.S.’s initial spring lockdown, the weather was rather temperate in most areas of the country. By the time COVID-19 outbreaks started becoming more rampant nationwide, summer was in full swing. This made for uncomfortable conditions in terms of social distancing guidelines. For example, the pandemic forced hundreds of restaurants to seat more patrons outside — right about the time a heat wave swept the country.1
Expenses like future energy bills are worth considering as part of your retirement income plan, because they can cause your household bills to fluctuate once you’re on a fixed income. Consider investments in your home you can make now to help curb bills, power grid shutdowns or both. We can help you with creating your long-term budget to help you determine your future retirement income needs. Contact us to learn more.
Because this summer was particularly harsh in many areas of the country, the demand for air-conditioning increased. According to the Netherlands Environmental Assessment Agency, the global demand for heating energy is expected to rise throughout the short term, and then level off around 2030. However, the energy demand for air conditioning is expected to increase rapidly all the way until 2100, even surpassing energy demand for heating by the middle of this century.2
Worldwide, there are currently about 2 billion air conditioning units in operation — mostly in residential buildings. In the U.S., 87% of homes use air conditioning. About one third of our energy bills represent heating or cooling; in some areas it’s more than half. On an individual household basis, residents can save 3 to 5% in air conditioning expenses per each degree increase on the thermostat.3
One of the newer innovations in electric grid savings is the use of battery packs to store energy sources, including energy absorbed by solar panels. Not only can this help your own house maintain a desired temperature, but less usage can help reduce strain on your local power grid. The use of battery storage is increasing rapidly as commercial and industrial companies are using up to five times more energy storage resources this year than the previous year. This has helped reduce peak electricity demand this summer in densely populated states like New York, California and Massachusetts.4
Energy storage units use distributed energy resource (DER) optimization software
to reduce energy by switching to the storage system at peak times instead of siphoning power from the grid. This type of software uses machine learning to determine a facility’s behavior and anticipate electricity consumption, which is saved into the software’s algorithm. By continuously evaluating this information within the context of market prices, utility rates, demand response, demand charges and battery storage, the software transfers usage to energy storage resources during times when it is most financially prudent.5
