Electricity costs: the price cap is 28 pence per kWh in the UK
The price of electricity has been a growing concern for many households in the UK. Energy bills have been increasing, prompting people to look for ways to cut down on electricity usage. The energy price cap was introduced on 1 January 2019 by the regulator Ofgem to prevent households from being overcharged. The cap is reviewed and updated every three months, with the price cap level for the next period announced in advance. For example, the price cap between 1 July and 30 September 2025 was set at £1,720 per year for a typical household using electricity and gas and paying by Direct Debit.
The price cap limits the maximum amount suppliers can charge for each unit of electricity and gas, and it sets a maximum daily standing charge, which is a fixed amount that must be paid to have access to energy, regardless of usage. The standing charge is currently £296 per year for households with both gas and electricity.
The price cap is based on wholesale energy prices and applies to providers' standard and default tariffs, which most households use. It is designed to ensure fair pricing for those on standard variable tariffs and to reflect the cost of energy. The cap does not apply to fixed-term energy deals.
With the electricity price cap set at 28 pence per kilowatt-hour (kWh) in the UK, the cost of running electric lights can be calculated. For example, a 5W LED bulb, which is equivalent to a normal 50W bulb, running for 6 hours per day for a month will cost around 26 pence. This is significantly cheaper than using candles, which would cost much more for the same amount of light output.
In summary, the electricity price cap in the UK is 28 pence per kWh, and electric lights are generally much cheaper to use than candles. The price cap helps ensure that electricity remains affordable for households, especially when compared to alternative lighting options.

Candle costs: burning a cheap candle for an hour costs 2.9 cents
The cost of lighting a home is a significant concern for many, especially with the steep rise in energy bills. Some may consider switching to candles as an alternative to electric lighting, but is this a cost-effective solution?
A box of 72 8-10 hour candles costs $18.99. If each candle burns for 9 hours on average, that's 648 hours of light for $18.99, or 2.9 cents per hour. In comparison, a 60W incandescent light bulb costs about 0.72 cents per hour to run, based on an electricity price of $0.12 per KWh. This means that burning a cheap candle for an hour costs about four times as much as using an inefficient 60W light bulb for the same duration.
However, it's important to consider that candles vary in price and burn time. For example, tea light candles cost approximately $19 for 200, burning for about 4 hours each, which works out to be 0.02 cents per hour. On the other hand, taller dinner-style candlesticks that burn for 6+ hours can cost up to 75 cents each.
While it's true that electric lights are generally more efficient and cost-effective, the type of bulb used also makes a difference. LED bulbs, for instance, are the cheapest to run and can be purchased for as little as £12 for a pack of 10. Using a 5W LED bulb for 6 hours a day over a 30-day month will cost around 26 pence, or £3.12 per year.
In summary, while a cheap candle may cost 2.9 cents to burn for an hour, this is still significantly more expensive than using electric lighting, even with the current high energy prices. Candles may be a good backup option for power outages or to create a cosy atmosphere, but they are not a financially viable alternative to electricity for regular lighting needs.

Electricity usage: most is used by the refrigerator and air conditioner, not lights
With energy bills on the rise, many people are looking for ways to cut down on electricity usage. One way to do this is to switch from electric lighting to candles. However, it is important to note that electric lights are almost always much cheaper than candles. For example, burning a cheap candle for an hour costs about four times as much as using an inefficient 60W light bulb for the same duration.
While lighting does use a significant amount of electricity, especially if the lights are on for most of the day, it accounts for about 9% of a typical home's energy use. In contrast, the refrigerator and air conditioner are the most significant energy consumers in a home, making up 26.2% and 31.3% of a home's total energy consumption, respectively. Therefore, while switching to candles may seem like a good idea, it is more effective to focus on reducing energy consumption from these major appliances.
There are several ways to reduce energy consumption from your refrigerator and air conditioner. For example, you can ensure that your refrigerator is well-maintained and energy-efficient. Regular maintenance, such as cleaning the coils and replacing the door seals, can help improve its efficiency. Additionally, you can adjust the temperature settings to find the optimal balance between food safety and energy efficiency.
When it comes to your air conditioner, it is important to use it only when necessary, such as during the hottest parts of the day. Regular maintenance and servicing of your air conditioner can also help improve its efficiency. Another way to reduce energy consumption is to opt for more energy-efficient appliances, such as a toaster oven, microwave, or slow cooker, instead of the oven or stove. These smaller appliances require less energy to operate and can help reduce your overall electricity usage.
In addition to focusing on major appliances, there are other ways to reduce your electricity usage. For example, you can switch to LED lights, which are more energy-efficient and cheaper to run than traditional incandescent bulbs. You can also be mindful of your entertainment electronics, such as televisions and video game consoles, which can utilize a significant amount of electricity, especially when left on standby mode. By being mindful of your energy usage and making small changes, you can significantly reduce your electricity bills and contribute to environmental protection.

Candle drawbacks: naked flames can be a danger, especially with pets or children
While candles and electricity have both been used for lighting, the former has some drawbacks compared to the latter. One of the main disadvantages of candles is the safety risk they pose due to their open flames. This is especially concerning when there are pets or young children in the household.
Candles with naked flames can be a significant fire hazard if not carefully monitored. According to the National Fire Protection Association, half of all candle fires started when a flammable item, such as furniture, mattresses, bedding, curtains, decorations, paper, or clothing, was too close to the lit candle. It is crucial to keep candles away from anything that could catch fire and to never leave a burning candle unattended. This can be particularly challenging in busy households with people coming in and out or when celebrating occasions like Diwali, Bonfire Night, Halloween, or Christmas, where decorations and costumes can increase the risk of fire.
The presence of pets or young children further exacerbates the danger. It is essential to keep candles out of their reach to prevent accidental knocks or burns. Even a moment of distraction can lead to a potential fire hazard. Additionally, pets and children may not fully comprehend the dangers of an open flame, making it challenging to ensure their safety around candles.
Furthermore, the act of blowing out a candle, while traditional, can be risky. The flying sparks from blowing out a candle can ignite flammable materials nearby. Instead, using a spoon or another non-flammable implement to extinguish the flame is recommended. These safety considerations highlight why electricity, with its cost-effectiveness and lack of open flames, is generally a safer and more convenient option for lighting than candles.

Eco-considerations: candles emit 10 grams of carbon per hour of burn time
While candles may be more expensive than electricity, there are other factors to consider when comparing the two, such as eco-friendliness. Candles produce emissions that can be harmful to the environment and human health.
Candles emit 10 grams of carbon per hour of burn time. This includes emissions of carbon monoxide, carbon dioxide, NOx, and organic compounds such as formaldehyde, benzene, and polycyclic aromatic hydrocarbons. These emissions can have negative effects on indoor air quality and human health, with carbon monoxide being a particular cause for concern.
The type of candle can also impact emission levels. For example, candles made of paraffin wax may emit higher levels of carbon monoxide and other toxic chemicals, while those made with soy or coconut wax are believed to produce lower amounts of carbon monoxide. Additionally, scented candles have been found to emit different levels of certain compounds compared to unscented candles.
To minimize the risk of carbon monoxide poisoning, it is recommended to ensure proper ventilation when burning candles and to consider using LED lights as a more eco-friendly alternative. LED lights are not only more energy-efficient but also eliminate the potential dangers associated with open flames, making them a safer option for households with children and pets.
While candles can create a soothing ambiance, it is important to be mindful of their potential impact on the environment and human health. Therefore, when considering the choice between electricity and candles, it is essential to factor in these eco-considerations and prioritize sustainable and safe alternatives.
