That’s 7 Percent more power using less natural gas than the 22kW, and 14 percent more power than the 20kW on slightly less gas. The most efficient conventional gas-fired storage water heaters are ENERGY STAR models with energy factors between 0.67 and 0.70, corresponding to estimated gas use of 214 to 230 therms/year. As illustrated, even when a range of electric prices are considered, natural gas prices are consistently two to three times lower than electric prices.
In an op-ed, our researcher Jonathan Buonocore argues why companies' climate pledges must include emissions reduction strategies to protect frontline communities. A new inventory of air pollution impacts from stationary sources over the past decade shows this trend may continue. Increasing ventilation is one of the most accessible and important actions to reduce sources of indoor pollution. Opening windows and turning on a vent that exhausts to the outside when cooking are simple steps that can lower the risk of indoor exposure. The Consumer Product Safety Commission has the authority to set performance standards for gas stoves and ventilation hoods to limit air pollutant emissions.
Consumption & Efficiency
Wood is used as a main heating fuel mostly in rural areas but many homes throughout the country use it for supplemental heating. Approximately 10% of households in 2015 used a heat pump as their main heating equipment. 1 The number of homes with small-scale solar photovoltaic systems has increased substantially in recent years. Broad ranges in winter temperatures and capabilities of different technologies mean that certain heating choices are better suited to certain climates. Overall, 47% of households rely on natural gas as their main heating fuel, compared with 36% who rely on electricity.
The Northeast is the exception, as both natural gas and electricity have been increasing while distillate fuel oil and kerosene have declined. Despite this massive increase in the proportion of homes using natural gas, the actual volume of natural gas consumed has not increased to the same degree, due to increased efficiency of natural gas appliances. Modern top of the line gas furnaces can achieve efficiencies of over 90 percent . Even low-end natural gas furnaces achieve high efficiencies, around 78 percent. Households using propane to heat their homes consumed on average 20 GJ of fuel per household.
Heating equipment and heating fuel
Energy Star is an internationally recognized symbol indicating that the product has been tested and found to meet or exceed higher energy efficient levels without compromising performance. The purchase of energy efficient appliances is another way households can reduce the amount of energy they consume in the home. In 2011, 71% of households in Canada used at least one Energy Star appliance . The main refrigerator was the most common Energy Star appliance, found in 50% of households, followed by the washing machine (48% of households). The quantity of energy used by a household depends on many factors, such as the type and size of the dwelling, the quality and condition of its insulation, windows and doors and number of people living in it. Households with multiple occupants may use more electricity for heating water , cooking and home entertainment .
However, for both periods the most common retrofits were improvements to heating, ventilation or cooling equipment and improvements to doors, windows, exterior siding and caulking. The main type of heating system used by households varied depending on the province . While furnaces were used mainly in Ontario and the Prairie Provinces, electric baseboards were used by the highest percentage of households in Quebec (66%), Newfoundland and Labrador (56%), and New Brunswick (48%). Canadian households use energy in their homes to heat, cool and light their homes, heat water, and run appliances such as stoves, refrigerators and other devices such as televisions and computers. The amount of energy used within a home depends on many factors such as climate, fuel prices, the number of people in the household and the age, construction and size of the dwelling.

For convenience, DOER uses the term households when referring to the ACS data. To get a LEED certification of a certain level, you will have to build your house in a neighborhood that is surrounded by trees and should have green spaces. The eco-friendly interiors with trees and greenery will ensure that you stay connected with nature as well as with mainstream society.
Electric heat pumps are well-suited to the relatively mild winters in hot-humid areas and some mixed-humid areas. Of the 12.1 million households that use electric heat pumps, 9.3 million are in these two regions, which cover much of the Southeast. Electric resistance heating is effective but relatively expensive to operate. There is no definitive answer to this question as it depends on a number of factors, such as the size of the home, the number of people living in the home, the climate, and the appliances used.
That adds up to millions and millions of fossil fuel furnaces that need to be replaced. Until fairly recently, the conventional wisdom was that highly efficient natural gas furnaces were the environmentally preferable option, given that electrical appliances often draw on coal-heavy grid power . Natural gas heat is still generally considered the cheaper option (though, as we will see below, that’s not always true). On a national basis, natural gas has long been the dominant choice for primary heating fuel in the residential sector. Lately, electricity has been gaining market share while natural gas, distillate fuel oil, kerosene, and liquefied petroleum gas have declined.
However, natural gas burns hotter or cooler depending on its precise chemical makeup. As a result, natural gas providers use an adjustment called the “therm factor” to calculate how much energy you’re using. Natural gas providers give you a price “per therm” of natural gas you use. Will switching to a cheap natural gas plan save you hundreds of dollars, or just a few pennies? Here’s what you need to know about typical natural gas consumption in different households.
Water heaters, especially, can be scheduled to heat their water at night when power is cheap, or at midday when more solar is on the grid. They can also provide “ancillary services” like frequency regulation to the grid. Third has to do with electricity rates and how they’re structured — whether they are a flat rate or vary with the time of day. I found, in my quest to ditch oil for electricity, virtually no encouragement, help, or guidance from any agency or organization.
Major Democrat-led cities such as San Francisco, Seattle, Denver, and New York are on the offensive. Lawmakers proposed or enacted measures calling for a ban or discouraging the use of natural gas in homes. Annual residential natural gas bills vary across Canada from $727 to $1,432 per year, depending on the climate and gas supply circumstances in the region.
Households using natural gas consumed an average of 92 GJ of this fuel per household. In New England as a whole, a smaller share of households heat their home using natural gas. Heating oil remains the second most prominent heating fuel, closely behind natural gas. Lack of natural gas infrastructure in Maine, Vermont, and parts of New Hampshire means less access to gas supplies. Several New England states offer incentives for high efficiency electric heating technologies which is increasing conversion from oil-sourced heating to air-source heat pumps.
