Saving energy at home
Hello we are Laszlo, Max and Julia. We are going to do some research on saving energy at home. We’ll describe how we use energy at home and how much energy we use at a regular sunday (from 9am till 9pm). With this we’ll come aware of how much energy we use, and for what we use the most energy. We’ll look for what we use the most energy and find some ways to reduce our energy consumption which you can also try yourself. Secondly we’ll make an interview to ask to a company which is specialized in materials to save energy at home and we’re going to find such a house in which that method is being used and estimate the amount of energy which can be saved by this method. We’ll hope after you’ve read this article you’ll also help saving energy at home, because if everyone helps maybe we can make the world more green, so go green! Plan + task division Plan

Energy consumption at home on sunday
Home measures Laszlo Brief introduction: I live in Bergambacht, a place between Schoonhoven and Bergambacht, I live together with 6 people, a brother, 2 sisters and my parents. My brother is 17 years old and my sisters are 12 years old and 19 years old. We use electricity in our daily lives very often like every other person in the world. I mainly use my electricity for charging my stuff because the batteries are low, but my family may be using the electricity for other things. We try to save energy just like every other person in the world; try to shower shorter, use power-banks instead of the outlet. We also have solar panels on our roof and we mostly have too much energy because our solar panels work very good. House and expectations: Here are a few pictures of my house. As you can see we have solar panels attached to the roof and they are collecting sun everyday. When we all get up in the morning (everyone wakes up at a different time) one of the first things we do is showering, everyone of us showers around 5-10 minutes. The heating we don’t use when it is hot outside (summer, spring) but when it gets colder we turn up the heating so that it stays warm inside (autumn, winter). We use a lot of electronic equipment such as an xbox, phone chargers, computers etc. We also quite often use the dishwasher and the washing machine for clothes. But furthermore we try to save electricity as much as possible.
Home measures Julia Brief introduction: I live in a home at Bergambacht with my parents and 4 other brothers and 1 sister, so seven persons. My brother Bram is 18 years old, Joost is 16 years old, Dirk and Marieke are 13 and I'm 14 years old. I think our main use of energy is showering. However we do have limits on how long you may shower in our house (we only may shower 5 minutes). Secondly we use a lot of electricity for the water kettle and other stuff.
House and expectation: This is my house. We need to heat our house every day, however we don’t use any gas, water or electricity for it because we’ve got hearth. We make around 10 cups of tea a day, so the kettle is used ten times a day. The coffee maker is also used around 10 times a day. Everyone in our family showers one (or 2 times) a day, this means our shower is used around 8 times a day for usually around 5 minutes. We use the TV everyday and charge seven smartphones everyday. We have got 3 chromebooks and 4 laptops. I think the sum of all the devices will cost is a lot of energy. Secondly I think the water consumption will be very high because of the showering.
The measurements: This sunday everyone was home the whole day, which doesn’t happen very often. This means we’ve used even more energy then usual: Electricity: My mother has been vacuuming the house for 1 hour: the vacuum cleaner uses around 2000 Watt per hour, which is 2 kWh. The kettle is one of our biggest electricity consumers. Today the kettle is used 11 times, we’ve got a kettle which uses 1725 Watt per hour. The kettle is on 11 times 5 minutes so, 55 minutes, which is around an hour: 1,725 kWh Two TV’s (one downstairs for football, the news, etc., and one upstairs for Nickelodeon) were on for around 2 hours, so together 4 hours. They’ve been on standby the whole day which uses around 0,3 Watt per day. This together is around 0,22 kWh The dishwasher has been running one time today. We put them on the ECO modus which is around 50 degrees. However it does take a little bit longer. The energy consumption of a dishwasher (on ECO modus) is on average 0,93 kWh The freezer is a big energy the consumer as well as the refrigerator. Both have been running for 12 hours. We haven’t got a big freezer but we do have a big refrigerator. Our refrigerator and freezer use around 1.5 kWh per day Dirk, Marieke and I, have got a chromebook (all the same one: HP Chromebook g5 ee), which uses a 45 Watt netadapter. Marieke didn’t charge her chromebook. Dirk and I did for an hour, which means two hours: 90 Watt, which means 0,09 kWh My parents, Joost and Bram, have a laptop. Bram and my mom didn’t use it. However my Joost did for 3 hours, my dad used it for 2 hours. The laptops both used around 65 Watt per hour, there are two laptops so, 0,13 kWh, this for 5 hours is 0,65 kWh We live with 7 person in one house, so also 7 smartphones. However smartphones don’t consume a lot of energy because they haven’t got big screens. Everyone in our family charge the smartphones 1 or 2 times. I have charged it today 1 ½ times and my brother Bram did as well. Together we’ve charged our smartphones 8 times which is 0.06 kWh The lights: Marieke has got 3 lights bulbs in her room, which have been on for around 2 hours. Bram has got 2 light bulbs in his room which have been on for around 8 hours. Joost has got 4 light bulbs in his room which has been on for 3 hours. My parents have got 4 light bulbs which have been on for 5 hours. Dirk has got 3 light bulbs which have been one for 7 hours. I have got 3 light bulbs which has been one for 5 hours. In the kitchen we have got 8 light bulbs which has been on for 24 hours. Upstairs in the living room we have got 4 light bulbs which have been on for 12 hours. In the living room downstairs we have got 2 light bulbs which has been on for 6 hours. The light bulbs in the bathrooms have been on for 8 hours. All together the lights bulbs have been on for 68 hours. We have got energy-saving lamps, which consume around 15 Watt per hours. This is around 0,02 kWh per hour. We used the lamps for 68 hours so: 0,02 x 68 = 1,36 kWh We didn’t use the oven today which is usually a big consumer.
Together we use around 8 kWh per day. Four persons use on average 5.2 kWh per day, but then the wasmachine and the tumble dryer are included and it is for 24 hours (but that doesn’t make a big difference because you don’t use a lot of energy in the night). This means we are a little bit below average, I think that’s mainly because we haven’t used the radiator, wasmachine and tumble dryer.
Water consumption: Today everyone showered once. We’re allowed to shower 5 minutes because else we consume to much water. This means the shower is used 35 minutes. A shower uses 7.8 liter per minute on average this means we have used 273 liter water. My mother used around 2 liters of water for cooking We drunk around 3 liters of water (for making tea or just drinking water) To flush the toilet cost around 5.7 liter everyone goes to the toilet twice a day, and some three times per day, which means we flushed the toilet around 20 times today. Which is around 114 liter. For washing our hands, brushing our teeth and all the remaining stuff we use around 8 liters a day
This means we consume around 400 liters of water per day. An average person uses 119 liter of water per day. Which means we use a lot less water per person then the average person. I think this is because we only shower 5 minutes.
Methods to save energy at home
Laszlo: In order to save a lot of energy at home;
We take short showers;
We have solar panels on our roof;
We do not use a dryer for the clothes
Instead of turning up the radiator we put on some warm clothes.
Julia We have got a few methods to save energy at home
Put the hearth one instead of the radiator, this doesn’t reduce the Co2 emissions but it does make the electricity bill less high
Shower five minutes, this reduces the water bill and is also good for the environment
Put the lights out when you leave a room
Use electricity-saving light bulbs
The hearth is only on downstairs, if you get cold upstairs you should put an extra sweater on instead of putting the radiator on
Put curtains in front of the windows and night, this keeps the heat inside.
Interview
can you introduce yourself? I am Dimitri Noorlander I am 30 years old and I work for pk zontechniek a part of electro H. oudenes
Can you give us a brief description of the company? well we sell and inform people about solar panels it’s is not very large, it’s more of a people working for the people type of company.
What kind of energy saving products does your company produce? well like he name of our company already states we provide solar panels and information about solar panels and their electricity gain.
Can you explain us how these products decrease your energy consumption? well they transform the rays of sunlight into electricity and that either get stored, used immediately or send to a elektricity power plant that sends it to other houses, so in a way your helping society
Can you give me a brief explanation about how your company produces these goods, is that in a green way? well i don’t actually know if we produce them like greenpeace wants to make them, but I think that we in numbers don’t add anything to the greenhouse effect because we make other people add less carbon dioxide to the air.
Do you think these products that your company sells must be installed in every house and why? Ofcourse we need to preserve our planet, but just solar panels aren’t going to do it, it would be a good start and I think that it would be really cool if everyone would get their electricity from the sun
How much energy can be saved by using that product on average? Around 250 kw a year.
What do you think is the most important thing people have to have in their house to save energy? well I don’t have a lot of energy saving items in my house but if I would have to name the best overall energy saver inside your house would be those energy saving light bulbs, people seem to underestimate how much energy they actually save
Julia and Laszlo have been measuring there energy consumption at a sunday, in what way do you think Laszlo and Julia and their families can reduce their energy consumption? By installing more solar panels and by just looking at how much electricity they are using, and reducing the unnecessary electricity expenses, like leaving a light on the entire night for example.
