# Energy efficiency labels Vs Prize tags: why are both important

– Energy efficiency labels –

If you have recently bought a home appliance like a dishwasher or a washing machine you most probably know

If not, you must know that the energy efficiency labels aim to be a clear and simple indication of the energy efficiency of product at the point of purchase.

The ratings on the energy efficiency labels go from A+++ to D (A+++ being the most efficient and D the least efficient).

Those ratings are defined by the EU for each type of appliance (e.g. fridge, tumble drier,…) through a number of different tests and criteria. This means the ratings can only be compared between one type of appliance (e.g. fridge to fridge).

– Prize tags –

And, well, when it comes to the prize tag, the more efficient the appliance the bigger the prize will be. This is because the energy efficient appliances use less electricity and water than those less efficient appliances.

– The dilemma –

The dilemma is: Is it really worth to buy a more expensive but also more efficient appliance or should I buy the less efficient but more economic appliance?

The answer is: Depends on how high the prize tag is.

Let’s have a detailed look.

## Buying and energy efficient appliance: Payback period

You have to choose between two fridges:

– Fridge A: It uses 252 kWh per year and it has a prize tag of 899 euro

– Fridge B: It uses 174 kWh per year and it has a prize tag of 1159 euro

Fridge B it is more efficient but also 260 euro more expensive that Fridge A so, which one do you choose?

The only way to make an informed decision is to figure out how much electricity you would be saving per year by choosing fridge B, and then calculating how many years it will take for those savings to compensate the initial extra 260 euro.

We know that we are paying 0,217 euro per kWh (do you know what a kWh is?) so for us that means that

Fridge A will have a yearly electricity bill cost of  252 x 0,217 = 54,7 euro

– Fridge B will have a yearly electricity bill cost of  174 x 0,217 = 37,8 euro

For us, there is a difference of 16,9 euro per year on electricity cost between the A+++ and the A++ fridge.

That means that if we buy the A+++ we will be paying an extra 260 euro but we will be recovering that amount due to the lower electricity bill within 260/16,9 = 15,4 years…

Well, in this case the payback period it is far too long because nowadays a fridge does not last 15 years.

That means that for us it makes more sense to buy the cheaper and less efficient fridge.

## Conclusion

– Cost –

From the cost perspective, you really need to know how much you are paying per kWh before making an informed decision.

Do not just buy the more efficient but more expensive appliance by assuming that lower energy or water consumption will compensate for the higher prize tag.

– Environmental impact –

From the environmental perspective, of course that it would make more sense to buy the most efficient appliance but here comes into play the prize tag.

The appliances manufacturers and the distributors need to make sure that the prize tag it is reasonable.

# Dishwasher Vs Hand Washing: Save electricity, water and time?

We have an energy efficient dishwasher that we use efficiently and it only consume 0,15 euro in electricity and 0,024 euro in water per load.

Note that here the most important keyword it is EFFICIENT. Our dishwasher it is an ENERGY EFFICIENT APPLIANCE that we have learnt to USE EFFICIENTLY by learning what cycle consumes less energy and water.

For us it is a much better option to use the dishwasher rather than washing the dishes by hand because we are saving a considerable amount of time by using the dishwasher while saving water and not significantly increase the electricity cost.

Still, every case is different so we are going to show how you can find out if you are saving money, time and effort by using the dishwasher or if it makes more sense for you to clean your dishes by hand.

## Dishwasher Vs Hand Washing: Electricity consumption

– Dishwasher –

Our dishwasher, like any other dishwasher, has several cycle options. We have measured every cycle power consumption using a plug in power meter so we can know what cycle is the most economic. The results are displayed on the table below.

CyclePower consumptionTotal cost
70 degrees1,21 kWh0,31 euro
Auto0,80 - 1,10 kWh0,20 - 0,28 euro
Auto + Vario Speed1 kWh0,28 euro
Eco0,60 kWh0,15 euro

If you would also like to measure the power consumption of your dishwasher, have a look to the article where we show how to use a plug in power meter.

Since we came to know that the most economic it is the ‘Eco’ cycle, we are using this cycle every single time. It takes 3,5 hours to complete the cycle, but we leave it working overnight so this is not an issue for us.

– Hand washing –

But, how much electricity would we be consuming by heating the amount of water needed to clean the plates by hand?

Well, first we need to know how much water we are using for cleaning the plates by hand and then calculate how much energy in kWh our boiler uses to heat that amount of water.

By washing the dishes by hand and measuring the water consumption, we know that we use 14 liters of hot water to clean by hand the same amount of dishes that we can fit on our dishwasher.

It is difficult to find out how much does it cost to heat up 1 liter of water but out of doing some research we estimate that it takes 0,05 kWh.

As we are paying 0,217 euro per kWh, that means that it does cost us 0.1519 euro to heat up 14 liters of water.

Power consumptionTotal cost
Dishwasher0,60 kWh0,15 euro
Hand Washing0,7 kWh0,1519 euro

RESULT

Energy wise, it does cost us the same to clean the dishes by hand or by using out dishwasher.

Even assuming that we are using the dishwasher 20 times a month (this estimation takes in consideration vacations) we are saving a meager 0,5 cents a year by using the dishwasher.

## Dishwasher Vs Hand Washing: Water consumption

– Dishwasher –

We have measured the amount of water needed by our dishwasher to complete a cycle. For this, we just started a cycle and checked on the water meter the amount of water consumed from start to finish.

As we know that we are paying 2 euro per cubic meter of water, we can easily calculate the water cost. The results are shown on the table below.

Standard Cycle15 liters0.3 euro
Eco cycle12 liters0,024 euro

We have an efficient dishwasher so it consumes very little water. If you would also like to measure how much water your dishwasher is using, have a look to this article where we show how to read a water meter.

Also, if you want to calculate the water cost but you are not sure how, start by having a look to this article where we explain what a cubic meter of water is.

– Hand washing –

Now we need to know how much water, hot an cold, we would be using to clean by hand the same amount of dishes that we are able to fit in our dishwasher. For that, we will also check on our water meter the amount of water consumed from start to finish.

The results are that we are consuming 12 liters of cold water and 14 liters of hot water to hand wash the dishes. Let’s not that we have tried to use as little water as possible.

Dishwasher12 liters0.024 euro
Hand Washing26 liters0,052 euro

Water wise, it does cost us just an extra 3 cents more to clean the dished by hand.

Assuming that we are using the dishwasher 20 times a month (this estimation takes in consideration vacations) we are saving 7,2 euro a year on water by using the dishwasher.

Also, from the environmental point of view, we are saving 220 liters of water per month, or 2640 liters of water per year.

RESULT

Water wise, we are saving water and money by using the dishwasher rather than washing the dishes by hand

## Dishwasher Vs Hand Washing: Time consumption

– Dishwasher –

It takes us around 5 min to load the dirty dishes to the dishwasher and another 5 minutes to unload then dishwasher. This is, a total of 10 minutes per load.

– Hand washing –

To clean that same load by hand and then put back all the dishes to their place it takes us 30 minutes.

RESULT

As we are using the dishwasher almost once a day, that means that by using the dishwasher we are saving a total of 20 minutes per day that we can use for other activities.

By estimating that we use the dishwasher 20 times per month (this estimation takes in consideration vacations), we can calculate a total saving of 400 minutes (or 6,6 hours) per month by using the dishwasher instead of cleaning the dishes by hand.

This is 6,6 hours per month or 80 hours SAVED per year, well over three full days, by using the dishwasher.

Time consumed (per month)
Dishwasher3,3 hours
Hand Washing10 hours

Just note that it takes over 3 hours for the ECO cycle to finalize. Those three hours in any calculations because our time it is not being consumed.

## Dishwasher Vs Hand Washing: Supplies consumption

– Dishwasher –

For washing the dished at the dishwasher, we use one dishwasher tablet per load that costs around 0,13 euro per unit. Also, every month we need to use some dishwasher care liquid to clean the dishwasher and each bottle does cost us around 2,5 euro in supplies.

– Hand washing –

By washing the dished by hand, we need to have some dish washing liquid that it cost us around 2,5 euro per liter. Also we need a dish washing sponge that it cost us around 0,3 euro per unit.

Assuming that we are using 2 sponges per month and 1 liter of dish washing liquid, washing the dished by hand does cost us around 3 euro a month.

Assuming that we use the dishwasher 20 times per month (this estimation takes in consideration vacations), using the dishwasher does cost us around 5 euro in supplies.

RESULT

From the supplies perspective, the difference between hand washing or using the dishwasher it is nearly negligible.

Supplies cost (per month)
Dishwasher5 euro
Hand Washing3 euro

## Conclusion

From the direct costs perspective (water and electricity), it is nearly cost us he same to wash the dishes by hand or using the dishwasher.

ElectricityWaterSuppliesTotal cost (per month)
Dishwasher3 euro0,48 euro5 euro8,48 euro
Hand Washing3,03 euro1,04 euro3 euro7,1 euro

Still, two other major factors they need to be taken in consideration:

– The cost of having to purchase an energy efficient dishwasher, which is approximately 700 euro

– The time saved by not washing the dishes by hand, which is approximately 6,5 hours a month.

Even though 700 euro seems like a big cost, if we assume that the dishwasher will last us for 5 years, using the dishwasher is taking out of our budget only around 12 euro per month.

ALL IN ALL

Using the dishwasher does cost us more money than if we would be washing the dishes by hand. Approximately an extra 13,5 euros per month.

Still, we consider that in our case, those 6,5 hours that we save every month by using the dishwasher are worth more to us than those 13,5 euro per month that we would be saving by washing the dishes by hand. That time is better spent playing with our children, relaxing or writing this article.

# Do rechargeable batteries save money and reduce waste?

Rechargeable batteries Vs disposable batteries: Is it really worth the hassle of buying a battery charger and charge the batteries when they run out of power?

Is it not way easier to change an already discharged battery for a new one and just keep that expended battery on a box until you have time to take it to a collection spot?

Well, disposable batteries may have both an economic and a environmental impact so keep reading to know if in your particular case it is is worth to start using rechargeable batteries.

IKEA has recently made an announcement stating that:

Following IKEA’s commitment to inspire and enable people to live a healthier and more sustainable life at home, all non-rechargeable alkaline batteries will be removed from the global home furnishing range by October 2021.

With this decision, IKEA wishes to inspire consumers who need to frequently use batteries to make a switch to rechargeable batteries.

Regular use over time enables consumers to both save money and reduce waste at home.’

On the same announcement, IKEA mentions that:

‘Already after 10 charges of a rechargeable NiMH battery, such as the LADDA range sold in IKEA stores, greenhouse gas emissions are lower as compared to using alkaline batteries to obtain the same amount of energy.

When about 50 charges are reached, the overall environmental impact [2] of NiMH batteries is equal or even less than the impact of using alkaline batteries.[3]‘

As well as:

‘ IKEA sold roughly 300 million ALKALISK alkaline batteries last year and estimates that discontinuing them could lead to a reduction of 5,000 tons of global waste if all customers switched to rechargeable batteries and used them at least 50 cycles (which is just 10% of the 500 charge/discharge cycles each LADDA battery is rated for).’

Well, from IKEA’s perspective, it really looks like that it makes sense to change to rechargeable batteries but let’s have a look to what is the economic and environmental impact for the average household.

## Is it worth to buy and use rechargeable batteries?

A rechargeable battery it is roughly 4 times more expensive that a disposable battery and on the top of that we also need to buy a battery charger.

Also, charging the batteries must consume some electricity so, does charging batteries increase our electricity bill?

All those factors need to be considered as well as each one’s individual case.

If you are an individual and you only use batteries for the TV remote control and maybe for your wireless mouse, then having to buy a batteries charger for the more expensive rechargeable batteries makes no sense.

This is because maybe you will be using a pack of 8 batteries per year so the payback period would be far too long. In your case, from the money perspective, it makes sense to use disposable batteries

Still, if as an individual you have a hobby (e.g. photography) that requires the frequent use of batteries, than it really makes sense to buy rechargeable batteries.

On the other side, if you have one or more children at home you must know that many toys consume batteries at an alarming rate so in your case it is quite probable that you will be saving money by using rechargeable batteries.

As shown on the picture above, it takes only 16 recharges to pay back the battery charger and the extra cost of having to buy rechargeable batteries. For some families, 16 battery recharges can take place over a single Christmas period…

But, how much does it cost to recharge the batteries? This factor should be considered when deciding if buying rechargeable batteries it is worth, isn’t it?

Well, personally I pay 0,217 per every kWh I consume and using a plug in power meter I have measured that charging 4 AAA batteries has cost me just over 2 cents. The cost of charging the batteries it is nearly negligible.

## The environmental impact of disposable or rechargeable batteries

But, apart from the cost, there is another very important factor that we need to have in consideration. The environmental impact.

According to a publication on  ‘For the impact categories Acidification, Human toxicity (cancer effects), and Particulate matter, an “inefficient” use of the rechargeable devices (for only 20 charge cycles or less) could cause higher impacts than the employment of disposable batteries.

Additionally, in the same publication it is stated: ‘Moreover, for the Ozone depletion, NiMH batteries are hardly environmentally better than alkaline batteries even with 150 recharges.’

And as conclusions and recommendations, the following it is mentioned in the publication: ‘The number of uses of rechargeable batteries plays a key role on their environmental and energy performances. When compared to disposable batteries, a minimum number of 50 charge cycles permits a robust reduction of the potential impacts for all the analyzed indicators excluding the Ozone depletion. Hence, the use of rechargeable batteries should be mostly encouraged for high consumption devices such as cameras, torches, and electronic toys.’

Well, all in all we come back to the same situation. If you are an individual barely using batteries, it may actually not be environmentally friendly to buy rechargeable batteries.

If you are an individual using a big quantity of batteries because you are into photography, or you have a hobby that requires many batteries, most probably you will be recharging the batteries 50 or more times within a few months. In your case, using rechargeable batteries you would be reducing your impact to our ecology.

And, in the same situation, if you have small children at home and plenty of toys using batteries, from the environmental perspective it makes sense to buy rechargeable batteries.

## Conclusion

It seems that the key factor to decide what type of battery is better for you it is the number of times you will be recharging it.

If a rechargeable battery is disposed before going through 50 recharges, the environmental impact is greater than using disposable batteries.

From the money saving perspective, if you are using a significant amounts of batteries per year, or even per month, it is really worth to consider to swap to rechargeable batteries.

## Where to buy a battery charger and some rechargeable batteries

It is up to you but I personally use the most basic and economic battery charger I found in the market.

If you want to have an idea of the cost range, have a look to the battery chargers in Amazon. Amazon sells some rather economic AAA/AA battery chargers as well as an assorted range of rechargeable batteries.

Have a look, compare the reviews and decide which one suits your needs.

# Energy efficient appliance payback period

An appliance that uses less power it is going to consume less electricity, there is nothing to argue here…

But, is it worth to pay more money for an appliance that uses less power?

For example, as shown on the image below, if you have to chose between a more expensive but a more efficient appliance or a more economic but less efficient appliance, which one would you choose?

## Buying an efficient fridge payback period

The payback period refers to the amount of time that it takes to recover an investment.

The more efficient fridge (A+++) it is 260 Euro more expensive than the less efficient one (A++) but it uses less electricity. Only 174 kWh per year, which is significantly less than the 252 kWh per year that the less efficient fridge will be using.

If we want to know if buying the more expensive fridge it is a good decision, we need to find out how long it will take to recover those 260 Euro through electricity savings.

Well, assuming a prize of 0,17 Euro per kWh, it will take us 20 years to recover those additional 260 Euro that it will cost to buy the more expensive fridge

The problem here is that it is very unlikely that a fridge will last for so long. Therefore, at 0,17 Euro per kWh, buying the more economic but less efficient fridge it is the best choice.

## Payback period calculator

Of course, not everyone pays the same prize per kWh so in order to know if buying a more efficient but a more expensive home appliance makes sense, we need to run some calculations.

With the calculator below, anyone can easily calculate the total cost (appliance cost + electricity cost) over time and decide which appliance is the most economic to buy.

As a rule of thumb, the higher it is the cost per kWh, the more makes sense to buy energy efficient appliances. If you don’t know what a kWh is or how much you are paying per kWh, have a look to this where we explain those concepts.

# Nimiq makes learning about crypto simple and easy

For most of the people, cryptocurrency and blockchain are vaguely familiar terms which are associated to Bitcoin and ‘stuff’ too complicate to understand or learn about.

To bridge the gap, Nimiq is making crypto simple and easy to use so everyone can learn about blockchain technology and start using cryptocurrencies.

The financial system revolution is already here and Nimiq will be your gateway towards learning and understanding cryptocurrencies and the blockchain. There are many opportunities already available to those who are willing to step out of their comfort zones and grab them. Will you?

## How to open a NIMIQ account

Nimiq can be used by anyone who have access to a web browser (Brave, Chrome, Firefox,Opera,…).

You can create a NIMIQ account in no time… if you don’t care too much about the avatar.

If you are actually looking for a cute avatar, to open an account it may take a couple of minutes until you find the right one…

Just give it a try and you will see.

Once you have created you first account, there are a few of ways to start earning your first NIM coins. After all, you don’t want just an empty account…

## Earning NIM through a NIM faucet

First and easiest, you can get some small quantity of NIM through this Nimiq faucet

It used to be possible to get 1 NIM per day but recently the amount has been reduced to 0,1 NIM. Still, this is a super simple way to earn some NIM every 24 hours.

## Earning NIM by mining

The second way to get some coins it is by mining NIM through a web browser. Without going into too much detail, anyone can mine NIM through a web browser (Brave, Chrome, Firefox,Opera,…) but you must be aware that it will take processing power and electricity.

Still, if you are using your PC or laptop anyway, it may be worth to have the Nimiq web browser miner running in the background as the additional amount of electricity consumed will not be significant. This way of earning NIM can be considered a way to earn

Just be aware that mining consumes CPU power which may make your PC run slower, but the processing power usage can be adjusted by increasing or decreasing the number of threads.

The process it is quite straightforward, once you know the basics, so it could be useful to first watch some Youtube videos and get to know the basics. Simply go to YouTube, type something like  ‘mining NIM through web browser’ and have a look to a couple of videos.

As you can see, we mine NIM on daily basis and the rewards are automatically paid to our account.

Mining NIM through the web browser is not the fastest or the most efficient way no mine NIM. As an alternative, it is possible to install a desktop miner which mines NIM at much quicker rate.

As shown in the picture below, with an i7 PC we are able to reach up to 31 kh/s which is around 10 times faster than mining NIM through the web browser.

Again, it is a quite straightforward process but could be useful to have a look to some YouTube videos first to know the basics.

## Earn NIM through donations

The third way is through donations. If you have a website you can add a NIM button so anyone with a Nimiq account can donate NIM to you.

This a more limited option available to those who have a website or a blog but if you want to see how it works, scroll down to the bottom of this page to see our donate NIM button.

## Where to use your NIM

Well, after earning some NIM maybe you may want to spend them so you have some options like purchasing gift cards or products from the Nimiq shop.

Eventually, maybe by middle next year, there will be more ways to use our NIM. Have a look to the Nimiq roadmap every so often to know about what are the plans of the Nimiq team and what they are planning to deploy.

By the way, one very good deal is to purchase a Ledger Nano S hardware wallet though the Nimiq shop so you can store your NIM on an extra secure location.

That you don’t know what is hardware wallet?! Well, that is normal because you have just started you Crypto journey and little by little, day by day, you will increase your knowledge.

## Keep learning

By now you should already be a proud owner of a Nimiq account, have got some NIM through and faucet and, maybe, have mined some NIM.

This post is just meant to show you a handy way to start giving your first crypto steps though the Nimiq blockchain. Now it is up to you to keep walking and leaning more.

Let us know what do you think of this post. We have tried to keep it simple but we can expand it if anyone has questions or wants more details

## How to save electricity at home

If you are considering to mine Nimiq or any other cryptocurrency, you must know that mining can consume quite a bit of electricity.

Still, there are ways to save electricity at home that can compensate for the electricity used for mining crypto.

In this video we are showing you where we are using the most electricity at home and ways to reduce your electricity consumption.

All our videos can be found in YouTube, in both and Spanish languages.

Additionally, if you are looking for energy saving opportunities but you don’t know where to start, use our electricity usage calculators to become aware of your electricity consumption, the electricity costs and the potential savings.

# - Laundry washing ball - How to wash without detergent

We have been using a laundry washing ball at home at we can state that it works for us.

For those clothes that do not have any major stains, the laundry washing ball it is more than enough to have the clothes washed properly.

DETERGENT

We are paying 15 euro for a 3,5 liters detergent bottle that, at 70 ml of detergent per cycle, allows us to run 50 cycles per bottle of detergent.

Or, what it is the same, a cost of 30 cents per washing machine cycle.

LAUNDRY WASHING BALL

We have paid 16,95 euro for our washing ball and it has a lifespan of 1000 washing cycles, or three years, which gives us a cost of 0,016 euro per washing machine cycle.

Cost per cycle
Detergent30 cents
Laundry washing ball0,016 cents

## How does the laundry washing ball works?

The washing ball that we are using works by using a combination of magnets, minerals and ceramic balls.

This combination it is used to increase the water PH value so impurities can be loosen more easily and washed away.

You just need to put the washing ball inside your washing machine drum along the clothes, and that is it. Your clothes will be washed and no harmful substance or bleaches from detergents will finish up as part of the groundwater.

You can even add some fragrance for a natural laundry scent.  During the washing process, the fragrance is distributed throughout the laundry.

Just remember that after 25 washes should you place your washing ball in the sun to reactivate the effect of the mineral and ceramic balls.

## Sustainable washing

Conventional detergents release ingredients into the ground water that are difficult to degrade and cannot be fully filtered by sewage systems.

The fragrances, bleaches and ingredients contained in detergents are a burden for the ecosystem.

Additionally, many of these ingredients cause allergic reactions in humans.

By using a laundry washing ball instead of detergents, you will be actively avoiding the pollution of the ground water and protecting the environment sustainably.

## Save money on your laundry and reduce the cost per load

Do the math. It is very simple.

You must already know how much you are paying for your laundry detergent and how many loads you can run per bottle or per pack.

Now just divide the cost of the detergent by the number of loads and you get the cost per cycle.

A laundry ball can be used up to 1000 times so it is just matter of dividing the cost of laundry ball by 1000 to know the cost per cycle.

Cost per cycle
Detergent30 cents
Laundry washing ball0,016 cents

## Choosing a laundry washing ball

Clicking on the picture below will redirect you to the Amazon Germany website and to the product we have purchased for own use but, if you cannot get the same exact product in your country, there are many other vendors to choose from.

Just have a look to the product reviews to find those with the most positive feedback.

We want to leave very clear that for those clothes with major stains the washing ball may not be able to fully remove the stains. In those cases we are using detergent, until we come up with an eco friendly alternative.

For those clothes which just require to be washed up and refreshed, a laundry washing ball it is perfect alternative to detergents.

# Water usage calculator

Do you know how much water is your household using daily?

Is it 50, 100, 200, 300 or even more litres a day?

It may come to a surprise to get to know how much water we are using every single day and how much of that water it is being wasted.

Many of us are lucky enough that our water cost it is relatively low, it may amount to just one or two euro per 1000 liters of water, but that doesn’t mean that we should be wasting water.

## Simple water consumption calculator

If you want to find out how to know how much water you are using, first have a look to this post.

If you already know how much water your household is using, use the calculator below to find out how much money you are paying per year and how much could you have by reducing your water consumption.

## Shower water consumption calculator

The fist step towards reducing our water consumption it is to be aware of where and how much water we are using. It is quite common to see advice like, reduce the length of your showers and save water but there is more to it.

If your shower head water flow rate it is very high, you may be wasting water. Instead of reducing your shower length, it may be enough with reducing the water flow.

## Tap water consumption calculator

The same principle applies to our water consumption in other areas, like the tap water consumption.

Do you need to consume 6 liters per minute to just wash your hands?

Do you need to consume 6 liters per minute to just clean your teeth?

It is both important to control the time using water and the water flow rate as both factors determine how much water we use.

# Learn how to read a water meter

A water meter it is a device that measures and records how much water it is being consumed over a time.

Every time that we use water at home, the amount of water being consumed it is accounted by the water meter and the reading on the water meter it is used by the water providers to invoice us for our water consumption.

Most of the households have a water meter and every so often someone is coming to get the readings.

This is what most of the people knows about water meters but for those with a little more of knowledge and awareness the water meter can be a very useful tool to learn about our water consumption habits and find out ways to reduce our water consumption.

» Do you know how much water you are using every time you are having a shower?

» Do you know how many liters per minute you bathroom tap is consuming?

» Are you wasting water without knowing it?

If you want to learn how to read a water meter and decrease your water consumption, have a look to this video from the Youtube Effiworkx channel.

In this video where we are explaining not only how to read a water meter and what a cubic meter of water is but also how this knowledge can translate into reduction our water consumption.

## Water consumption calculators

For those which access to the water meter, it is quite simple to figure out the daily water consumption and the total cost.

The calculator below calculates the water cost per year based on an average daily consumption.

# What is a cubic meter of water?

A cubic meter (m3) of water is the equivalent to 1000 liters of water.

1m3 = 1000 liters

The cubic meter is the measurement unit used by the water providers to calculate the water cost based on an agreed cost per cubic meter.

Most of the houses have a water meter which measures the amount of water being consumed and if we are able to understand the value displayed by the meter we can calculate the water cost by ourselves.

As an example, the water meter below is showing a water consumption of 1,214 cubic meters (m3) which is the equivalent to 1214 liters.

1,214 cubic meters x 2 euro per cubic meter = 2,5 euro (approx.)

## Water consumption calculator

For those which access to the water meter, it is quite simple to figure out the daily water consumption and the total cost. The calculator below calculates the water cost per year based on an average daily consumption.

# - What is a Kilowatt Hour (kWh)? -Find out how much electricity you are using at home

A Kilowatt Hour (kWh) it is a unit of measurement used to measure electricity consumption.

Therefore, if you are really interested in knowing how much electricity you are using at home and how much the electricity cost is, you need to learn what a Kilowatt Hour is.

For example, as you can see on the picture below, this household is using an average of 2700 kWh per year and it is paying 0,2173 euro per kWh they consume.

If we multiply the 2700 kWh by 0,2173 per kWh, this gives us an electricity variable cost of approximately 600 euro per year.

One Kilowatt (kW) it is the equivalent to 1000 Watts (W) so, for example, if we have a 60 Watts bulb and we want to find the equivalent in Kilowatts we just need to divide 60 by 1000 and that gives us a power consumption of 0,06 Kilowatts.

60 W /1000 = 0,06 kW

If we want to know how many Kilowatts hour are used by that bulb over a period of 10 hours, we just need to multiply 0,06 kilowatts by the 10 hours and that gives us a total of 0,6 Kilowatt Hours (kWh).

0,06 kWh x 10 hours = 0,6 kWh

## Watt (W), Kilowatt (kW), and Kilowatt Hour (kWh) relationship

In this video we are explaining how Watts (W), Kilowatts (kW) and Kilowatt Hours (kWh) are related and how this knowledge translates into useful applications like deciding if purchasing a more energy efficient appliance it is really cost effective.
