How to save money with tech: Smart lighting

Any home or small office can have intelligent lighting that works only when a room is occupied. Unless you are determined to divest yourself of cash you should consider LED bulbs.

How to save money with tech: Energy-usage monitor

Energy-usage monitors are your friend. They keep you accountable, inform you of how much energy you’re using within the home in real time, how much it’s costing – and how much you can save, prompting a change of expensive habits if need be.

There are two types of energy monitor – hand-held screens that work alongside a separate unit, which can clip onto your electricity meter, or online house energy monitors.

Smart meters may soon be rolling out, replacing current meters. Information on your gas and electricity could be automatically sent straight to your energy supplier using wireless networks, getting rid of manual reading.

The Geo Minim Electricity monitor alerts the user to unusual patterns of energy, and uses a CT clip around the mains incomer. It has an easy-to-read LED screen too. You can buy it from Amazon for £35 here.

Other energy monitors include Efergy’s portable e2 or the same company’s Engage Hub, which displays real-time electricity usage on your web browser or via a smartphone app.

How to save money with tech: Efficient showerhead

The average shower in the UK lasts eight minutes, and in that time around 60 litres of water is used, water that uses energy to heat. With an efficient shower head, you’re restricting the volume of water coming through.

The Ecocamel Jetstorm Plus can be used with all shower types, including electric showers, and offers three spray patterns. The showerhead injects air into the water stream so you use less water.

You can buy the Ecocamel for £40 here.

How to save money with tech: Hybrid computers

A laptop that is also your desktop and a tablet is more than just a cool gadget and a way to work on the hoof. Hybrid devices mean one computer instead of several: and that has the potential both to save you money, and to save precious resources. The most energy a computer will ever use is in the construction of its parts, so being able to use a single laptop or tablet wherever we are is a huge efficiency. And – obviously – buying one device rather than three is a good way of saving money, even if you will have to shell out to get a decent hybrid.

How to save money with tech: Keep your old PC

Not unrelated is the value of keeping your existing computer rather than giving in to the constant upgrade cycle. Computers these days last longer than once they did, in part because of the greater reliability of components, but also because once you have a sufficiently fast system with enough storage, there really is no need to upgrade. Reader, we are at peak PC.

This can lead to inefficient power usage, of course. But the laptop that lasts for five years is better for the environment than replacing it with a brand new and more efficient device every year or two. We all change our phones far too often, too.

You can elongate the life of most tech hardware without having to replace the whole thing. Replace that inefficient spinning hard drive with an SSD. Displays can be replaced or upgraded, as can power supplies.

If you do have to buy a new phone or PC, be sure to recycle your older kit, either by donating it, selling it or passing it on via a freecycle site.

You will want to keep your internet router turned on when you’re at home during the day, but there’s no realy reason for it to be on when you’re asleep. Some routers offer a power schedule which you can program to make it turn on and off automatically.

How to save money with tech: Standby power

The average household spends around £70 per year keeping household electronic devices on standby. That’s over 10 percent of a house’s total electricity consumption. Think about those TVs, set-top boxes, DVD players, PCs, audio systems and games consoles. Do you really need to leave them on standby through the day and night?

Obviously it makes sense to leave a Sky or Virgin box on standby if you have scheduled programme recordings, but aside from that items can be completely switched off.

How to save money with tech: Solar charger

So you’re saving energy on your big home gadgets, but what about the small gadgets that still need charging every night? Why not investigate a solar charger, which just requires the power of the sun in order to charge your smartphones, tablets and cameras? Check out our review of the best solar chargers here.

How to save money with tech: Kitchen tech energy saving tips

You can’t turn off your fridge or freezer at night to save money but you can cut down these devices’ electricity usage. Keep the inside of a fridge between 0-5°C. Defrost food in the fridge, as frozen food helps to cool the fridge. Keep your fridge and freezer at least three quarters full, recommends Which? Magazine. You could fill them with bottles of water to take up space – although over-filling will stop air circulating round the compartments properly.

• Washing clothes at 30 degrees C as opposed to 40 degrees C, uses 40 percent less energy and is generally as efficient, according to the UK’s Energy Saving Trust. Look for Eco cycles to further cut power.

• Don’t pre-rinse dishes before putting them in dishwasher. This can save a significant amount per year. If you have a water meter letting the dishwasher do all the cleaning is more efficient than putting stuff under a running tap.

• Use your dishwasher only when it is full, maybe every two days.

• Adjust the water level on your washing machine to match the load size, especially when using hot water. Always use a cold rinse. Also, clean the lint filter regularly.

• Try not to use a clothes dryer. Tumble dyers and the like are incredibly energy greedy! Which? Calculates that one load in a C-rated electric tumble dryer costs around 49p, compared to just 14p per load in an A-rated heat pump dryer.

• Don’t overfill your kettle, just boil the amount of water you need. Check how much energy a kettle uses with an energy monitor. You’ll be shocked at how much electricity is used making a cup of tea. And keep it descaled, as all that limescale makes the kettle work harder to boil.
