Whilst we can’t control the weather that the good Lord has given us, there are still ways in which we can become more energy efficient. By targeting the most energy-consuming appliances and prioritizing energy-saving practices, we can reduce our bills and make our homes warmer on those cold winter nights.
Electricity consumption in U.S. homes varies by region and type of home
Electricity bills vary in the United States. The National Renewable Energy Laboratory reports that the average U.S. household consumed 11,012 kWh of energy in 2008, but this figure varies considerably depending on location and housing type. On average, apartment buildings in the Northeast use less energy than single-family homes in the South. Apartment buildings are more likely to use gas for heating and hot water and to use electric heating in the winter. They also tend to have more insulation than single-family homes.
Electric power is the most technically advanced and reliable generation source available today. Unlike natural gas, petroleum fuels and wood, which are needed for a handful of uses such as heating and cooking, electricity can power those and well over 100 other energy end uses for households.
The three largest categories and their shares of residential electricity consumption in the USA in 2015 were; air conditioning 17%, space heating 15%, water heating 14%.
Each year, billions of lights are lit across the world. In the US alone, about 12% of all electricity is used for lighting.
Air conditioning use is now common in most homes
No matter how you look at it, air conditioning has been one of the fastest-growing energy uses in homes over the past few decades. Nowadays about 87% of homes use some sort of AC. Back in 1980, only around 57% of homes used it. The percentage of homes with central air conditioning has more than doubled since 1980 when 27% of homes had central air conditioning systems compared to 64% in 2015.
The HVAC system is the most energy-consuming system in a home. According to Energy Star, your whole-house HVAC unit is responsible for 46% of the energy consumption in your home – even more than refrigerators, washers, dryers, and water heaters. All HVAC systems require some amount of energy to operate. In an average 24-hour period, a system running continuously would use somewhere between 28 and 63 kilowatt hours (kWh), depending on its efficiency. The lower efficiency units would use around 850 kWh per month, while the higher-end units could use 1,950 kWh in a month’s time. Here are a few ways you can reduce energy usage
Most homes have refrigerators and many have more than one
Your home is likely to have a refrigerator. Most people in the United States do. About 30% of American homes have two or more refrigerators. These extra refrigerators are more common in the Midwest than in other parts of the country.
Refrigerator No. 1 can accommodate an average of 39 items per week at a cost of $0.10 per item, whereas Refrigerator No. 2 can accommodate 27 items per week at a cost of $0.08 per item. A separate freezer that is only used six months of the year costs an average of $69 per year to operate.
Your refrigerator, although an essential part of your life, actually uses a lot of energy. An average fridge uses 225 watts when it’s on, so if you leave your fridge on all day, you’ll use 162 kilowatt-hours per month. Over the course of a year, this amounts to 488 kWh or $57.36 at today’s prices. Although you can’t turn your fridge off or decrease how much time you spend in your kitchen
A water heater that uses natural gas or electricity can use nearly 30% of your home’s energy. Conserve power and save energy with a tankless water heater, which uses 60%-80% less water than a traditional water heater. This also results in an annual 10% saving on your utility bills.
Dishwashers use a lot of energy. They can cost you more per month than your light bulbs. You probably don’t think about them much, but you probably should. There are some easy changes you can make to reduce the amount of electricity your dishwasher uses.
Washer and Dryer
Washing machines and dryers use a considerable amount of energy, accounting for about 5 percent of your home’s total energy usage. These appliances consume about 3045 watts/hour each, which means that both machines together can consume roughly about 91 kWh per month if they are used for one hour every day.
Electric Oven and Stove
At an output of 2,500 watts and 1500 watts respectively, on medium-high heat for one hour a day, these appliances can result in 75 kWh and 45 kWh a month, respectively. These appliances, particularly your oven, can increase the temperature of your house which also increases the amount of electricity needed to keep it cool.
You need a light bulb that will help you stay environmentally friendly and save money on your power bill. That is why you should use a LED Light Bulb. It is a more sustainable and energy-efficient alternative to traditional lighting. It can help you save up to $50/year in electricity costs. A common household item, light bulbs are essential for illuminating homes across the country. Most bulbs require about 10 watts of energy per hour to function. In some states, more than 35 percent of a residential electricity bill is spent on lighting.
Television and Media Equipment
Electronics incorporate everything including computers, televisions, and tablets. Electronics make up about 4 percent of our energy use. Our electronic entertainment in particular, including laptops and video gaming programs, can consume a significant percentage of our residential energy. If you watch an average of five hours of TV a day and play video games for 6.3 hours a week, your electronics can use about 55 kWh per month. These electronics are also culprits of using standby power even when they are not in use.
