Gas generally appears cheaper per kWh. However, appliance energy efficiency and usage are crucial for a comprehensive comparison.
Energy efficiency: A key factor in cost
Appliance efficiency is as important as price per kWh in determining overall energy expenses. Appliances converting energy more effectively require less energy, potentially offsetting electricity's higher unit price.
Comparing appliance efficiency
Household appliance efficiency varies significantly. These differences can inform choices about which appliances to use. This section explores how specific choices impact overall energy costs.
- Heating: Gas boilers typically achieve 80-95% efficiency. Electric radiators boast 100% efficiency. Heat pumps, with a Coefficient of Performance (COP) over 3, generate more heat per electricity unit. The Energy Saving Trust notes potential savings of between £165 and £690 per year when switching from a gas boiler to a heat pump.
- Cooking: Gas cookers are less efficient than electric cooktops. Induction cooktops directly heat cookware and offer more efficiency than radiant electric or gas options.
- Water Heating: Electric water heaters can be more efficient, especially on-demand models. Tank heaters lose heat, reducing efficiency.
- Lighting: LEDs consume up to 75% less energy than incandescent bulbs, offering cost savings and a longer lifespan.
Consider heating a small room requiring 1 kWh of energy. An electric radiator directly consumes 1 kWh of electricity. An 80%-efficient gas heater needs 1.25 kWh of gas. Factoring in unit prices, the cost difference may decrease due to gas heater inefficiency.
| Appliance Type | Efficiency |
|---|---|
| Gas Boiler | 80-95% |
| Electric Radiator | 100% |
| Induction Cooktop | 84% |
| LED Bulbs | 75% more efficient than incandescent |
Certain electric appliances may compensate for electricity's higher price, mainly long-term. Choosing efficient appliances helps minimize energy bills.
Consumption patterns and scenario analysis
The most cost-effective energy source depends on your home's energy use. Various factors such as home size, occupancy, and appliances will drastically affect your energy needs. Analyzing usage patterns can assist in determining the overall energy cost.
Scenario 1: gas central heating in a standard home
Most UK households use gas central heating for hot water. Gas also fuels cookers. Electricity powers lighting, appliances, and electronics. This configuration often results in gas as the primary energy expense.
- Heating, hot water, and cooking primarily rely on gas, affecting the energy bill.
- Electricity largely powers lighting and appliances, a secondary expense.
For such households, gas is the larger expense due to heating demands. Consumption habits will determine the breakdown. A well-maintained boiler can reduce gas use. For instance, a household might use approximately 12,500 kWh of gas and 3,100 kWh of electricity annually.
Scenario 2: All-Electric residences
All-electric homes use electricity for everything, including heat pumps, induction cooktops, and electric vehicles. Efficiency makes this surprisingly affordable.
- All energy needs are met through electricity.
- Solar energy use can greatly cut electricity costs.
All-electric homes benefit from heat pumps, which produce more heat per electricity unit. Solar panels can further reduce costs. All-electric homes might use roughly 10,000 kWh yearly. Investing in a 4kW solar panel system can cut yearly bills by up to £500. The upfront cost is high but long-term benefits outweigh the initial financial hurdle.
Scenario 3: small apartments without central heating
Smaller dwellings may use electric heaters and water heaters, primarily in older buildings. This results in higher electricity use, especially in winter. Gas bottles offer an alternative for some in order to reduce the amount of electricity use.
- Electricity is primarily needed for heating, causing a high electricity bill.
- Bottled gas helps in cutting these expenses.
Managing electricity consumption is essential for these homes. Energy-efficient heaters and reducing water usage help. For example, a small home using electric space heaters may consume approximately 6,000 kWh annually. Prioritising insulation ensures that you get the best mileage out of your electric heaters.
