The importance of Bee's and their problems in climate change:
Audio: Elevator pitch
Many big car companys like Mazda, VW-AUDI Group or japanese companies like Honda are developing "E-Fuel" cars. Also BMW is looking into the technology and trying to get petrol cars with "2-Butanol". These cars should use very little and organic fuel which would be really environment friendly. This could be a great alternative for the electrical cars, which sometimes are far worse for the enviroment as a normal petrol car. Currently the VW-AUDI Group is looking forward to release their first full E-Fuel 911 Porsche in 2025.
Is E-Fuel really an alternative? Could current petrol cars getting an "upgrade" for E-Fuel? Are electric cars really good with the lithium batteries?

So I was thinking about, if it`s possible to survive 100 years in a 200 square meters in a closed space with 12 other people underground the earth. I`m going to have a look at all the possibilities. Leave a comment down below if you have some information.
Livia and I thought, that it would be interesting to know how the clothes in India are produced and how bad the transport to the markets in Switzerland is for our environment. Is there an eco-friendlier way to transport the clothes? Why don't we produce the clothes only in Switzerland instead of abroad?
We'd like to collabrate with some students form India to find out more about the clothes production there. We also would like to get in contact with some clothes stores in Switzerland and try to find out from which country they get/import their clothes.

Can glacier melting be provided?
How dangerous is glacier melting for the humans, the animals and the nature?
EN - Fast fashion has changed the textile industry from the ground up. The clothing industry is virtually flooding the planet with textiles: 56 million tons of clothing are sold every year. Influencers and neuromarketing are driving sales. But cheap clothing comes at a high price, such as precarious employment conditions and the disastrous environmental balance.

Hydropower is the usage of water to operate machines or generate electricity. Water is in a constant state of movement through a huge global cycle: it is evaporated [1] from lakes and oceans, it forms clouds, it drops as rain or snow, and then it returns to the sea. The energy of this water cycle, which is powered by the sun, can be drawn on to generate electricity or for such mechanical tasks as the milling of grain [2]. Hydropower uses a source of fuel water [3], that is not reduced or used up in the process. Because the water cycle is an infinite, ever-renewing system, hydropower is classified as renewable energy.
If running water is captured and transformed into electricity, it is referred to as hydropower or hydroelectricity. There are various types of hydropower plants, they are all powered by the kinetic energy of flowing water as it moves downstream. Turbines and generators turn the energy into electricity, which is then fed into the power grid [4] for use in households, companies and industries.
Types of hydropower and dams
There are different kinds of hydroelectric power plants [5], all of these are powered by More...
Wood is one of the oldest used plants and one of the most important plant-product as a resource. It's considered humankind’s very first source of energy. The deforestation was one of the first big intervention of mankind in the ecosystem. Today it is still the most important single source of renewable energy providing about 6% of the global total primary energy supply. More...
The term "geothermal energy" refers to the energy that is stored in the form of heat below the earth's surface. At a depth of around 15 metres the temperature of the ground is constant throughout the year. In Switzerland, generally speaking the temperature below the surface increases by around 30° C per thousand metres of depth. The temperature at a depth of 5,000 metres is approximately 160° C. Significant quantities of heat above 40° C are available at depths greater than 1,000 metres. This geothermal energy can be extracted with the aid of a variety of methods.More...
"Biomass" is a fancy word for something very simple: stuff that’s found in nature. People have used biomass energy ever since the very first caveman (Höhlenmensch) thought to make a fire out of wood! Today, biomass power plants use everything from animal waste to wood pellets to create electricity. There are lots of advantages to biomass energy, which is a renewable energy source.More...
In our cellar we have a heating and oil storage room (Heizungsraum und Heizöltank). Almost all the homes in our neighbourhood use oil for heating. Its sadly not the most eco-friendly way of heating.
We also have underfloor heating in most rooms in our house like the kitchen and bathrooms. This is very practical because it saves lots of space. (You don’t have a big heating unit in the centre of the room).
In the cold Winter months, we heat our house with a small wooden oven. It gives a nice cosy winter cabin feel. You’d be surprised at how much heat can be produced in this small fireplace (see picture below). We use local wood to support climate friendly transportation emissions.
