Save loads of money on energy by:

Energy Saving – Save Electricity.

There are a few ways we can conserve energy by looking specifically at how we use electricity in the home.

Use Led or Energy-efficient Lightbulbs

ThisisMoney claims that for every light bulb you replace, with an energy-efficient one, you save £3 a bulb over the year.

This mounts up to saving over £100 of energy just on one simple change.

Another cool fact is that the bulbs last 10-20 times longer, so you will save a fortune over time!

For example, 20 years @ £100 = £2000

There are super cheap bulbs online now – it's worth a look. 

LED light bulbs

These bulbs should be around $15 for six and come in whichever fixing you need (bayonet or screw) 

Check current prices on energy-efficient bulbs. 

Conserve Energy by Using Energy-efficient Appliances

No, I'm not suggesting rushing out and buying all new appliances.

When it's time to replace an appliance, looking at the energy rating will save you a considerable amount.

Prices are more expensive, but the operating costs are between 9% and 25% lower per year.

EnergySage's article has examples of what you can save on different appliances.

For example, ENERGY STAR-certified clothes washers consume at least 25% less energy and 45% less water than conventional ones, whereas ENERGY STAR refrigerators use only 9% less energy. So is it does to do research before buying to consider this carefully:

At what rating would it save you the most money on energy against the costs of  buying it?


This Bosch Washing Machine uses 35% less energy, so it pays itself quickly over time. It has a triple-A rating.

Energy Efficient Kettles


The Breville Hot Water dispenser is by far the most popular energy-saving buy of our readers.

It is versatile, as you can make only one cup at a time, yet it has a superb tank, holding 1.5l. (5 – 7 cups worth)

Making a few cups at once has a super quick boil time for each cup of 50 seconds—ideal for busy families.

It also has a tonne of 5-star reviews. If you can get it for under $35, grab it!

Install a Smartphone-controlled Energy System

My husband has installed Smart Things.

This allows us to:

  • To set the lighting as we want.
  • To set the heat in the house how we want it in different rooms.


In the dining room at night, as we walk through the kitchen, the light is triggered by a sensor and lasts for 5 minutes.

 All the fittings we have bought using Zigbee or Z wave technology.

We sat together and talked about where in the house we use the most energy, heat, what doesn't need to be on, etc.

First, we fitted controllable valves to our radiators, Â so now we can heat our house zonally. They are so easy to fit into standard radiators. Usually, they are around $50 each, so if you see them for cheaper, they are an absolute bargain.

Heating Zonally for Higher Energy Efficiency

Now we have a scenario where only the lounge and downstairs are heated in the evening, but then at 10 o'clock, the bedroom radiator is triggered to 20 Celsius so that I am warm when I go to bed.

We have seen savings of $30 a month on electricity and gas in total.

Switch Electricity Providers?

This guide from Dan over at the Financial wilderness debates whether it was an excellent idea to auto-switch your energy bills in 2021.

A Reliable Smart wireless thermostat is essential to energy conservation in the home.

Now we have a Nest Learning Thermostat connected to the system. It means we can control the boiler direct from our phones also!

We have an energy-efficient Vaillant boiler, which is superb and exceptionally well made, but the wireless thermostat they supplied might as well be kicked down the road.

It was constantly losing connection and, therefore, losing us money via wasted heat. Please don't ever try Vaillant's wireless thermostats!

We have been on holiday in America, and it was cool to switch on the bedroom lamp! Seriously though, you should consider investing in a system like this.

Save Electricity Tips

Don't Overfill The Kettle.

  • Filling the kettle unnecessarily causes you to use too much energy for the water you need. The BBC claims it can save you up to $68 a year.

Switch Appliances off at The Plug

  • The electricity saving on this is not to be sniffed at – it will bring $30 a year extra to the pot, according to Moneysupermarket.com.

Fill Your Freezer Up.

  • Filling your freezer up will be a significant energy saving. It will keep the cold within the food. Therefore the freezer needs less energy to keep it at a constant temperature. This will give the machinery inside the freezer a break. This also works the same with your fridge.

Avoid Using The Dryer To Conserve Energy.

  • Driers suck up energy – try and hang your clothes outside. Not only will you be more energy efficient, but you will also be using the world's natural resources for free.

Fill The Washing Machine as Fully as Possible.

  • I manage to have two full washing loads every week. This maximizes the space inside the machine. It doesn't save a fortune, but on an A-rated machine, it will save you $4 a year on your electric bill. This works well with a dishwasher, also.

Wash at Lower Temperatures

  • Did you know that washing at 30 degrees can be a third cheaper than at 40? Moneysupermarket believes it could lower your electricity bill by around $52 a year.

Other Methods of Energy Conservation To Save Money

Insulate The Loft

  • Use loft insulation to line your loft and stop the heat from escaping from the roof. Look out for deals from the local DIY store. Sometimes they offer this for free, depending on the government's policy on energy.

Upgrade To Double-glazed Windows

  • In one house we fitted these in, the electricity and gas bills compared to the previous were halved – it's ridiculous, I know, but true.

Change That Old Wooden Door to a Composite Door.

  • Wow, what a difference this made – we don't have places with a significant temperature difference in the house. Composite doors are priced between $600 and $1000 but are well worth their weight in gold.

Buy Smaller Appliances

If you invest in a large American fridge, don't be surprised if it uses lots of energy. If you keep your appliances compact, they will use less energy overall.

Invest in Cavity Wall Insulation

If this is possible for your house, this is a big win – mainly if your house is the end one in the row and has one wall against the cold winter air. Look out for free energy grants from local companies – we had ours at the time, done for free.

Shut Doors in Rooms You Are Not Using

This keeps unnecessary cold air in rooms where you have turned the heat down.

Shut Windows in Winter

Only air the house once a week – sounds a bit obvious, but if you have the windows open, you are letting your hard-earned cash float out of the windows in the form of heated air.

Turn Down Your Thermostat by One Degree

For every degree you turn down your thermostat, you could potentially save £50 a year. So crack out the woolly jumpers and put more layers on them instead of reaching for the thermostat too quickly. (the greenage)

In The Winter, Open Your Curtains During The Day

If you let the sunlight in, chances are it will contribute to heating your house during the day for free. So the base temperature will be higher throughout the evening, therefore not needing as much heat to heat it as hot.

Avoid Drying Clothes on The Radiator

It will save you money and make the boiler work harder to heat the room. There are also other reasons not to that bestheating.com goes into more detail in this article.

So as you can see, negligible savings all add up to give you a figure saved in the hundreds every year! Pretty amazing what things we can get started doing straight away.
