Our heat source at home is geothermal energy and we us underfloor heating. The house is almost ten years old.

The heat level can be regulated and have more different levels. Our heating will reduce additional costs.

Geothermal is renewable energy.

In this post it will explain how a wind turbine works and the context of its use in Switzerland. 

What is Wind and how we can use this to generate electricity?

Wind is the result of the sun's uneven heating of the atmosphere. Warm air expands and rises, and cool air contracts and sinks. This movement of the air is called wind. [1]

How does a wind turbine work?

The wind turbine consists of a mast, a rotor and a generator . The mast is up to 164m high, but can reach over 200m. The rotor has a diameter of up to 10 metres. This has an output of up to 2-3 MW. Behind the rotor is a generator which generates electricity through the rotation of the rotor. [2]

The picture shows a classic wind turbine on a wind farm on the water. [3]

Wind turbines use the kinetic energy of the incoming air to rotate the blades. The More...

Natural gas is a fossil fuel(1) that essentially(2) consists of methane(3). Methane is a hydrocarbon(4) with a high energy content that causes the lowest carbon dioxide emission of all fossil fuels. This hydrocarbon is split into hydrogen and carbon monoxide in the fuel cell system and converted into electricity. There is already an extensive(5) infrastructure for the production and use of natural gas. The natural gas resources are large, but ultimately finite(6). [1]

Gas is a non-renewable energy. Non-renewable energy is the largest part of Swiss energy consumption, namely around 79 percent. Because there isn't any fossil fuels found in Switzerland. That means they have to be imported from abroad. [2]

Photovoltaics 

Photovoltaics (PV) is the conversion of light into electricity using semiconducting(1) materials that exhibit(2) the photovoltaic effect. The photovoltaic effect is the generation of voltage and electric current in a material upon exposure to light. 

A photovoltaic system employs solar modules, each comprising a number of solar cells, which generate electrical power.  

PV installations may be ground-mounted, rooftop mounted(3), wall mounted or floating. The mount may be fixed or use a solar tracker to follow the sun across the sky. 

Did you know? The term "photovoltaic" comes from the Greek (phōs) meaning "light", and from "volt", the unit of electromotive force, the volt, which in turn comes from the last name of the Italian physicist Alessandro Volta, inventor of the battery.

The wind is a clean, free, and readily available renewable energy source. Each day, around the world, wind turbines are capturing the wind’s power and converting it to electricity. Wind power generation plays an increasingly important role in the way we power our world – in a clean, sustainable manner. More...

We heat our house with wood heating. The water is stored in a 5000 litre boiler. We also generate electricity with our own solar system. At its peak, it generates 5 kWh. We consume about 7GWh in a year.

We made it happen! Our post is finally on don't waste my energy!

We're really excited and happy with the result. The whole process was a great learning experience. 

Don’t forget to leave a comment;)

Thank you and kind regards,

Today we have to edit our text again, because the whole formation, we already did, got deleted. Another issue is that the formation we want to do will not be taken over and we have to do it again and again.

We are looking forward to finishing our project today and publish it on DON'T WASTE MY ENERGY! We hope that you enjoy reading our project.

Our goal was to enlighten the people on the subject of city parks and how they have a great impact on the world. We've learned a lot during the research and the progress of the project. We also were lucky, that we were able to work with the Grün Stadt Zürich and use their informations and documents.
Overall, it was a great project and we are looking forward to feedbacks on donstwastemy.energy.

After all these days we are ready to publish our work. In general, we had no trouble with Wordpress and took a lot of effort to present our project attractively. We are happy to show you what Green Roofs have to offer.

This link will take you to our project:
