Nuclear energy is primarily called the technology for secondary energy by nuclear fission. This technology has been used on a large scale to produce electricity since the 1950s.
As of January 2020, 447 reactor units with a total capacity of 397 GW were in operation in 31 countries. A further 53 reactor units with a total capacity of 54.7 GW are under construction. In addition, more than 100 nuclear power plants are planned for the coming decade.
Nuclear energy is obtained from nuclear, known as "radioactive" fuel. In this process, natural uranium is enriched and then used in a nuclear fission reaction to generate heat. Nuclear energy has the great advantage of being relatively cheap and environmentally friendly. At present, uranium is also still available in relatively large quantities.
However, the cost of mining uranium is very high. In addition, large amounts of CO2 are produced in the process, which has a very unfavorable effect on the climate. However, opponents see the greatest danger in the event of a nuclear meltdown.

Which raw material is needed?
A) carbon
B) uranium
C) palladium
D) copper
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.
Consumption in Switzerland
- Consumption in Switzerland increase every year -> also the waste
- 690 kg of rubbish per person in 2012 -> Nr. 2 waste producers in Europe More...
Future Mobility
I suspect that electric cars will prevail over the hydrogen cars in the long-term.
Through research, the batteries of the future will be better and more efficient. The new batteries will contain less of the rare metal like cobalt. The life span of the battery should also be longer. Many start-ups are working on recycling solutions.
In addition, in the last years the whole road infrastructure is being fully designed for electric cars.
Hydrogen cars are very dangerous and storage is very complicated. The production of hydrogen also needs a lot of energy.
Hydrogen is a very exciting topic. I think that hydrogen will become a good long-term solution for ships and airplanes. Trucks maybe, cars less.
