Make your home more sustainable

Improve your home’s insulation

Investing in proper insulation can regulate temperature all year round, keeping it warm in the winter and cool in the summer. The materials used to ensure that the temperature inside your home isn’t affected by the heat or cold outside. 

How much can you save?

With insulation, you could save up to 50 % on energy bills. 

Upgrade your boiler 

Getting a new boiler helps to set some money aside. Though splashing out might be costly and it isn’t really an exciting purchase, it is a long-term investment that can help your household save up. 

How much can you save?

That depends on your old boiler, as well as whether it uses electricity or gas. You can find calculators online that determine how much you will save up by upgrading.

Use smart power strips

Smart power strips are designed to improve the energy efficiency of your home. A lot of devices use electricity even on standby mode, the so-called phantom power. The special circuits of the smart power strip monitor and control the voltage in each outlet. When it recognizes that certain appliances aren’t in use, it automatically shuts off the power supply to that particular outlet causing you to spare some money.

How much can you save?

An average household could save up to €90 a year by estimations of the Energy Saving Trust. Don’t let the phantom electricity drain your power and wallet.

Use energy-efficient lightbulbs

Your home’s energy efficiency can be boosted by simply replacing your old lightbulbs with ones that employ new technologies. LED and CFL lightbulbs use less electricity than traditional lightbulbs, thereby decreasing your lightning bills.

How much can you save up?

Replacing your former lightbulbs with a modern LED version could cut your lighting bill by around 69 %.

Use energy-efficient appliances

Energy-efficient appliances use the minimal amount of energy required to complete a certain task. The potential to save money is enormous, but it is a long-term investment, as these appliances tend to be a bit more expensive than the not so efficient ones.

How much can you save up?

A four-person family can save up to  €80 a year by simply swapping their showerhead. Changing bigger devices may lead to saving around €300 every year. 

Install solar panels and an energy storage system

Out of all the listed tips, this one is intended for the long haul. There is a common misconception that installing solar panels breaks the bank. An investment up-front brings to a big return in the following years. 

To not waste any energy from your solar panels, it’s a smart idea to install an energy storage system. Such a battery stores all the excess, unused electricity produced by your solar panels. It can even store electricity when it is cheaper so that you can use it when it is more expensive. 

How much can you save up?

Installing solar panels may reduce your bill by up to 50 %. Adding an energy storage solution to it could decrease your bills by another 30 to 40 %. 

Use sparingly to save substantially

Turn off the lights

This one goes without saying, but I still have to. When you don’t need them, don’t use them. As my mom used to say, we don’t live in Bethlehem, no need to leave all the lights on.

How much can you save up?

That depends on what kind of lightbulb you have, but you can save up to €70 a year by turning off a single lightbulb for 18 hours a day. 

Take shorter showers

Who doesn’t like a long, hot shower? Your electricity and water bill. Taking shorter showers reduces your bills, it’s as simple as that.

How much can you save up?

Some estimates say you could save up to €120 every year by showering for 4 minutes instead of 12.

Air dry your clothes

It damages your clothes and it doesn’t do a favor to your bills either. 

How much can you save up? 

Up to €220 a year by switching from an automatic dryer to line drying.

Adjust your thermostat

There is no nicer feeling than being cozy and warm, while it’s freezing outside. And you don’t need to give that up. Lowering the temperature by just one degree can result in lower payments.

How much can you save up?

As much as €90 every year, without giving up any comfort. 



Some of this advice might seem pretty obvious, but actually doing it doesn’t always happen. Other tips may come across as being too expensive. While they may take a bit of payment up-front, the amount that you’ll get in return is well worth the wait.
