Winkraft means not only clean energy, but also angry residents and conservationists, especially in Germany, who are warning about the potential consequences of the expansion for birds and bats. But the large, stationary wind turbines are not the only way to convert the power of the wind into electrical energy. Airborne Wind Energy (AWE) uses … Read more
Federal Minister for Economic Affairs Robert Habeck is speeding up: to become independent of fossil energy imports as quickly as possible, he has presented the so-called Easter package. This also includes an expansion of wind energy in Germany. By 2030, new power stations with a total capacity of 110,000 megawatts must be built. For comparison: … Read more
It has been clear for several years now that the use of fossil fuels has no long-term future. For a long time, however, natural gas played a somewhat separate role. Some sort of bridging function was intended until the expansion of renewables had progressed far enough. This also applied to the planned hydrogen economy: here, … Read more
The environmental and climate balance of electric cars improves significantly when they are charged with green energy. It is not far from this realization to the idea of solar cars. Ideally, these no longer need to be charged externally at all, because they store the extracted solar energy directly in their battery. In practice, however, … Read more
Amazon obviously takes its climate goals seriously. In 2019, the group announced its intention to be CO2 neutral by 2040. To this end, the truck fleet is now being tackled: little by little the diesel trucks are being replaced by e-trucks. The first five vehicles will start in the UK. The new fleet saves 170 … Read more
Some things are not a luxury in themselves in this country – or at least not considered as such. This actually includes a warm apartment and electricity. However, rising energy prices currently pose major challenges, especially for relatively low-income households. And there is no relief in sight. On the contrary, according to the comparison portal … Read more
In principle, electricity can also be transported without a cable. This is reflected, for example, in inductive chargers for smartphones. Some developers are also working on systems that will transfer the principle to electric cars. The US military is pursuing even more ambitious plans. They want to drive troops into distant lands from space. Background: … Read more
Solar cells are made for sunshine, hence the name. As is known, the energy yield drops quickly on cloudy days and sharply to zero at night. For homes that are not connected to the electricity grid, this often means switching on an expensive battery that has to be discharged after a relatively short time. In … Read more
When the sun shines intensely, often more electricity is generated than is needed in Germany. The larger power stations will then be taken off the grid. When the weather is good, wind turbines do the same. There is a lack of storage which saves the energy during times when the weather is not cooperating. But … Read more
Fossil fuels are a finite resource. Even the largest oil and gas fields will eventually be exhausted. Until now, the finance companies have just moved on and looked for new sources. However, the fight against climate change makes it necessary to look for new and sustainable energy sources. This is where the old oil wells … Read more
