Which countries or areas in the world are the best in saving energy? Which countries are wasting the most energy and why?
Our target is to compare countries which are consuming the most energy and which are efficient in saving energy. We would like to give an overview of the „Top 5 in saving energy“ and „Top 5 in consuming / wasting energy“ and we want, that people start thinking about their wasting and how they can improve themselves avoiding too much waste. Our big challenge is to find a reliable map and sources.
Top 5 countries which save the most energy and are the most efficient
When speaking of Germany, it is not uncommon to hear the phrase “German efficiency.” Therefore, it is not surprising to find Germany on top of this list. According to a recent study put out by the American Council for an Energy Efficient Economy, Germany was the best country over all for energy efficiency, scoring high in multiple categories for a total score of 65 points out of 100 on their study.
While Ireland’s economy is based mostly on the service and IT sectors, the Land Of The Leprechaun did come in as sufficiently green. Ireland has reduced its carbon emission by 15% per year for the last several years.
Denmark has a population of about half the size of New York City, but, even still, its energy usage is remarkably low. Each Dane consumes about half as much energy as each American, and that does not have to do with the difference between alternating current and direct current.
The United Kingdom recently vowed to cut carbon emissions by a whopping 80% before the year 2050. And, in addition, the country’s main business, its financial sector, uses very little energy anyway.
Norway derives almost all of its energy from sustainably green hydroelectric dams and would be much higher on this list if not for its incredibly high per capita consumption of energy, which may be caused by its cold climate.

This map gives us a good overview of which countries are the most efficient. It is clear that we are not sure if this map is reliable but we just want to show you an overview.

Because of to the hydro- and nuclear power stations – which emit less CO2 – the Swiss electricity is with only 33 grams of CO2 per kilowatt an hour one of the cleanest in the world. This value is referred to as “CO2 intensity” and corresponds to the amount of CO2 that is produced per unit of electricity through the burning of fossil fuels (gCO2/kWh). Countries which produce their electricity with coal power plants have a much higher CO2 intensity: 800 to 1000 g CO2/kWh.
The European electricity mix has an average CO2 intensity of 524 g CO2/kWh. However, you must make a decision between the electricity which is produced in Switzerland and the current electricity which is consumed in Switzerland. The electricity which is produced in Switzerland has a CO2 intensity of 33 g CO2 kWh. However, CO2 intensity of our consumed electricity is about (129 g CO2/kWh) imported from Germany which are generating a lot of their energy with coal plants. The Swiss citizens have an emission of 5.6 tons of CO2 per year, which is the average in the world. The highest CO2 emissions have the countries of the Arabian Peninsula (20 to 40 tons per capita and year) followed by Australia and the United States (17 tons).
Despite their clean electricity, Switzerland is not the star in the international level, because CO2 emissions do not respect national borders. Switzerland must reduce greenhouse gas emissions.

5 countries which consume the most gas
In fact, there are many rankings of countries but they all show different results. In our case we used the foundings of the CIA pagestatistics about oil, gas, and electricity consumption. In the end it is not really possible to find a statistic which shows us which country is wasting the most energy. However, in this statistic you can see which countries in general use the most energy over all.

We asked the Swiss Government “why does Switzerland not belong to the top 5 countries in saving energy?“ We got the following answer:
“Wir sind uns bewusst, dass es in der Schweiz noch viel Potenzial gibt, um Energie zu sparen. Mit der Energiestrategie 2050 (admin.ch) möchten wir dieses Potenzial nutzen. Mit der ES2050 sollen nicht nur erneuerbare Energien gefördert und der schrittweise Ausstieg aus der Kernenergie geschafft werden, sondern auch die Energieeffizienz gesteigert werden. Weitere Informationen zu diversen Energiesparmöglichkeiten finden Sie bei EnergieSchweiz (energieschweiz.ch).“
Swiss Energy Strategy 2050 (admin.ch)
About the Energiestrategie 2050
„Bundesrat und Parlament haben im Jahr 2011 einen Grundsatzentscheid für einen schrittweisen Ausstieg aus der Kernenergie gefällt. Die bestehenden fünf Kernkraftwerke sollen am Ende ihrer sicherheitstechnischen Betriebsdauer stillgelegt und nicht durch neue Kernkraftwerke ersetzt werden. Dieser Entscheid sowie weitere, seit Jahren zu beobachtende tiefgreifende Veränderungen insbesondere im internationalen Energieumfeld bedingen einen sukzessiven Umbau des Schweizer Energiesystems bis ins Jahr 2050. Hierfür hat der Bundesrat die Energiestrategie 2050 erarbeitet. Sie basiert unter anderem auf den Energieperspektiven, welche zu diesem Zweck aktualisiert und erweitert wurden“
Am 4. September 2013 unterbreitete der Bundesrat dem Parlament ein erstes Massnahmenpaket für die langfristige und nachhaltige Sicherstellung der Energieversorgung. Der Bundesrat setzt in erster Linie auf eine konsequente Erschliessung der vorhandenen Energieeffizienzpotenziale und in zweiter Linie auf eine ausgewogene Ausschöpfung der vorhandenen Potenziale der Wasserkraft und der neuen erneuerbaren Energien
We have to say, that our research for countries which are efficient in saving energy was a success. On the other hand, the research for countries which are wasting the most energy wasn’t really a success because there weren’t enough representative statistics. For this reason we have different scales for the wasting/consuming countries divided in oil, gas, and electricity. As we have already mentioned, our challenge was to find a reliable source and map. During this project we gained a lot of information about different countries which enhanced our knowledge.

I think you have chosen a very interesting topic. It’s nice to know which country waste or save the most energy, because in the future it’s more and more important to reduce the energy consumption.
The only thing that also would be very interesting is which and how much renewable energy each country uses to produce energy.
It was very interesting to read your work and in my opinion you did a really great job.
I could learn a lot about this topic and I want to say thanks for your efforts.
With kind regards
Dear Q23 Team
I think your topic is very exciting and you guys wrote a very good contribution.
It is well structured, logical and gives enough information about these countries and their energy consumption. You also added the link after each topic and focused on different types of energy, which is great. I was quite suprised that countries like Germany and Ireland are the leading ones in energy saving. Furthermore the question why switzerland does not belong to the top 5 countries in energy saving was very intersting, because I automaticallly thought they already would belong to the leading countries in this field.
It would also be nice to know how countries like USA, Russia, India etc. can improve their energy consumption and also which countries try to use more renewable energy sources. You could also add some picures to it, that would make it more colourful.
Altogehter you’ve done a very good job!!

Dear Top 5 Countries Group
Your topic sounds very interesting. You give a very good insight about energy usage of every country and the ranking is well structured and informative. Also the idea to show first the countries with the lowest energy consumption and then the countries with most energy consumption is really interesting.
The only thing I miss is the information about the high consumption countries, like facts how much of which energy source they consume. And I would maybe add one or to pictures to shape your project a bit more colourful.
Dear Q23 Team,
you\’ve made a huge project or well, you wrote pretty much. In my opinion its really interesting to see which countries are using the most energy. It was a little surprise when i saw Iceland or Finland in the top 5 of the countries which consum most electricity per Person. You never think about countries like these because they seem to be so small but as we can see they need a lot of energy in their daily life!
Do you know why they use that much electricity?
The top 5 of the countries which consum most oil wasn\’t a surprise. Actually I thought that at least the USA would be in every list in top 3. And I also thought that Switzerland would be better because we always think switzerland is so clean and nice and stuff but when we see it overall we aren\’t that good.
I think you did a nice project and it\’s interesting to see which countries are using which kind of energy the most.

I was very interested when I read your work. The theme was very complex but in my view you have made a good job!
I was very surprised when I saw that Germany is the country which saves the most energy. On the other hand the fact that China, USA and Russia need the most energy was not so surprising for me because of their size and the high population.
In your work you wrote that Switzerland needs to reduce the greenhouse gas emissions. How could we do that?
The ranking with the different countries which you made were very useful and informative to understand your work. Good job!
