Using an electric blanket can keep you warm while spending very little on heating.

Top prize - the mighty electric blanket

Are electric blankets a secret weapon against the fuel crisis? And why do we think they are the most low-carbon prize in the Shop4good quiz competition?  Let’s talk about the benefits of electric blankets for saving money and CO2.  And we announce the winners of the Shop4good competition below.

Helping us reach net zero 

Heating British homes accounts for around 20% of the national carbon footprint, and is a major challenge on the path to net zero. The humble electric blanket has an astounding capacity to keep us warm with a fraction of the CO2 emissions - and cost - of room heating.  And as they cost little to buy, they could help reduce heating bills for those in fuel poverty.

Types of electric blankets

There are three kinds of electric blankets:  under blankets and over blankets for your bed, and electric throws.  Most models have 5-10 temperature settings and timers for 1, 3 or 9 hours (and can be switched off at any time).  There are also electric foot warmers for sitting on the sofa or working at your desk.  
  • Under blankets. These go on the mattress, under your sheets, and you sleep on top of them.  They warm the bed before you get in, or can be left on all night on a low setting in the very coldest of weather.  
  • Over blankets.  These go over a sheet over you, with a duvet or blanket on top.
  • Electric throws are to have over your knees when on the sofa or at your desk.  They come in a range of colours and finishes to look nice in your sitting room.  
  • Electric foot warmers are like a big woolly double shoe which you slip your feet into while seated at your desk or on the sofa.

Costs and CO2 emissions of electric blankets


Cost Savings 

With electricity currently costing around 25 pence per kilowatt-hour, an electric blanket typically costs a penny an hour to run.  Compare that to a 2,000 watt electric room heater which costs around 50p per hour or central heating at £1.50 or more per hour.  If you use it for 8 hours a day for the 5 coldest months the cost is just £10 a year for an electric blanket, whereas the room heater would be over £500, and a typical central heating system around £1,500.

Carbon Savings

The UK average CO2 emissions is 35kg per person per day.  If we use an electric blanket as our source of heating, it produces around 80g CO2 per day which is a tiny fraction of your carbon footprint - far less than one percent.  For the 5 coldest months, that would be just 10kg of CO2. While an average electric room heater would emit 500kg of CO2 (½ a tonne) for the same period. So electric blankets are phenomenally good for the planet and you pocket!

Quality of life

Using an e-blanket means you can feel warm while being in a cooler room - which helps you to be more alert while working or relaxing at home.  In spring and autumn it allows you to open the window a crack, increasing air quality which is good for long term health and wellbeing, while staying cosy.
