Gas prices have been through the roof in recent weeks.

Last week, the gas price briefly peaked at 162 euros per megawatt hour (MWh), making it almost 11 times higher than a year ago.

Although prices have fallen somewhat, they remain unprecedentedly high.

Due to the sharp rise in gas prices, the energy bill for many households is higher.

Fortunately, there is also something that can be done about it.

Below is an overview of five quick measures to save money on the gas bill.

The main reason for the sharp rise in gas prices is the increased demand for gas and a supply that cannot keep up. When demand is greater than supply, prices rise. Last year, the cabinet decided to "completely phase out gas extraction in Groningen as quickly as possible", making us more dependent on other countries. At the moment, they prefer to keep their gas for their own residents, unless the Netherlands pays coarsely for it. Although the rise in gas prices is not only a Dutch problem. Other countries in the EU, but also outside it, are starting to suffer more and more from the troubled energy market.

What can you do to reduce your gas consumption as much as possible? Cavity insulation, roof insulation, floor insulation (at the ground floor) and in any case double glazing. This is how the classic insulation advice can be summarized. You can hire companies for it or do your own work with insulation material from the hardware store, but in both cases you have to dig into the pouch. However, the difference in gas consumption with a house without added insulation is so great that insulation pays for itself quite easily: the annual gas bill can quickly drop by hundreds of euros. If you have two or more measures carried out in an owner-occupied home, you can also receive a subsidy to cover part of the costs.

Good wall and roof insulation make the biggest difference and are actually indispensable for those who want to live energy-efficiently.

But what if you are a tenant, you don't have time to do odd jobs for the time being, or you already have the four major measures in order - and are looking for some extra profit?

NU.nl has a list of practical tips, which hopefully you will still benefit from:

1. Also check the thermostat (before you close the front door)

The most important tip of all: don't forget the thermostat.

Saving gas is more than insulating, it also depends (of course) on how high you heat.

Is there no one at home during the day?

Then a few notches lower is actually so smart.

Are you a forgetful type?

Hang your house key next to the thermostat.

Then smarter heating may become part of your regular departure routine.

Alternative: a smart thermostat.

It knows when you're home and automatically adjusts the heating levels.

You can save more manually, says the Consumers' Association.

2. Ventilate, but not too long

Good habit: open the windows in the morning.

But then you also bring in the coldest air.

In winter it is therefore better to do this later in the day.

That can make a difference of 8 degrees.

And don't forget to close the windows again.

A house is blown through in no time, and with a forgotten open window or back door, your heating will continue to work hard all day.

3. Curtains closed - and open again (take advantage of every ray of sunshine)

You can take advantage of the weather forecast.

Will it freeze hard?

Closing curtains makes another difference to the weakest spot in your walls: the windows.

But don't forget to open the curtains again during the day, especially on south-facing windows: they act like a greenhouse - and the weak winter sun can also bring a few degrees of free heat into your home.

4. A green garden can help (preferably with tall trees)

Do you have a garden?

Be sure to plant a few trees!

In recent years, the tip was mentioned after summer drought and heat: remove tiles, put plants in.

A green garden retains moisture and can provide shade, keeping it cooler in the summer.

The reverse is also true in winter.

Then it is mainly about the wind: on the outside of the house the air is always in motion.

But the slower that goes, the less heat the walls and windows continuously give off to that air.

That is why it can make a big difference to heating costs whether you have a corner house that is on the wind.

So for those who still wanted to prune that wild hedge before winter, we have the simplest tip: don't do it.

And where a tall tree does not fit, ivy may be an option to give an unsheltered wall an extra blanket.

Every little bit helps.

5. Hot water contains a lot of energy (and you can recycle it)

Before we forget: we heat not only the air, but also our water with gas.

That is why, for example, taking shorter showers is a frequently heard saving tip.

But we do have another one: if you consider how much energy went into that water to heat it up, it's actually a real shame to always flush it away into the sewer immediately after use.

For example, do you have a bath?

Let your bath water cool down after use before you pull the stopper out.

That heat then moves into your house, so that your heating has less to do.

Washing up bowls, baby baths, cooking liquid from the pasta, you can also turn this into a hobby: hot water from the tap, cold water in the gutter.

Are you immediately rid of that dry air that bothers you indoors in winter?
