What You'll Learn
Electric heating
One option is to use a heat pump, which uses electricity to move heat from one place to another. In summer, it cools your home by moving heat from inside your home outside. In winter, it pulls warm air from outside and moves it indoors. Heat pumps are energy-efficient, save money, and work in cold weather. They also save you money in the long run by using less energy.
Another option is to use electric space heaters, which are portable appliances designed to heat specific rooms or areas of your home. They are a great alternative to central heating systems as they allow you to target your heating efforts to the room you are currently using. Space heaters with heat settings can help you regulate the temperature and save energy. Additionally, some space heaters have built-in thermostats that automatically turn off when the desired temperature is reached. Oil-filled radiators are another type of electric heater that retains heat better than other room heaters, continuing to radiate heat for a short while after being switched off.
To calculate the running costs of electric heaters, you need to know the power of the appliance in kilowatts (kW) and the electricity rate per kilowatt-hour (kWh). The average cost of electricity in the US is 16 cents/kWh, while in the UK it is £0.26/kWh, and in England, Scotland, and Wales, it is 25.73p/kWh.
It is worth noting that electric heaters can be expensive to run if used for long periods, so they should be used intermittently to heat a room, unlike central heating systems that can be left on for longer. Additionally, proper insulation in attics, windows, and basements can help reduce heating and cooling costs by up to 15%.
By reducing your reliance on fossil fuels for heating, you not only save money but also improve your health and contribute to the global effort to mitigate climate change.

Heat pumps
There are two main types of heat pumps: air-source heat pumps and ground-source heat pumps, also known as geothermal heat pumps. Air-source heat pumps are more popular for residential heating and cooling as they are cheaper to install. However, geothermal heat pumps are generally more efficient and have lower operating costs due to the consistency of the ground temperature throughout the year. Geothermal heat pumps can also control humidity and are very durable.
Minisplit heat pumps, a ductless variant of air-source heat pumps, are highly effective for homes without ductwork and offer an efficient alternative to baseboard heating. They can reduce energy costs significantly, especially for zone heating. In colder climates, a dual fuel system combines a heat pump with a furnace, providing an energy-efficient solution even on the coldest days.
Upgrading to an ENERGY STAR-certified heat pump can result in better efficiency and lower operating costs. Heat pumps with the latest inverter technology can provide high-efficiency performance even at extreme temperatures. Many states are now offering rebates for homeowners who switch to these models.
By switching to a heat pump, you can reduce your emissions, improve your health, and save money in the long run.

Water heaters
To reduce the environmental and health impacts of water heaters, it is essential to transition to more sustainable alternatives. One option is to use a heat pump water heater, which uses electricity to transfer heat to a water tank instead of generating heat. This type of water heater is more efficient than conventional electric water heaters and can save money in the long run. Additionally, by using electricity instead of fossil fuels, you can drastically lower your emissions, provided you live in an area with a clean electricity grid.
Another option for a more sustainable water heater is to use solar power. Solar-powered water heaters use the sun as a heat source, reducing your home's energy consumption by 40%-50%. There are two types of solar water heating systems: active and passive. An active system uses electrical elements to pass heated water through the heater and into your home, while a passive system relies solely on the sun and gravity to provide hot water. However, in colder climates, there may be concerns about the amount of water that can be heated by a solar-powered system.
While gas-powered water heaters are marginally better for the environment than electric heaters in some regions, they still produce a significant number of harmful emissions. Additionally, the cost of electricity generated from fossil fuels is subject to the volatile global fossil fuel market, which can result in unpredictable price increases.
By transitioning to renewable energy sources for water heating, such as heat pumps or solar power, we can reduce our carbon emissions, improve air quality, and protect our health and the environment. These alternatives are more cost-effective and environmentally friendly, making them a crucial step towards a more sustainable future.
