Most people will already be familiar with the basic situation: it is usually noticeably warmer in large cities than in the countryside. Urbanization, industrialization and climate change are responsible for different effects. As a result, the soil in the cities also warms up faster and only cools down later. An international research team has now … Read more
There is much to discover for divers around King Island in Tasmania. More than sixty sunken shipwrecks have already been found there. They are a testament to the power that the waves can unleash around the small island. This is exactly what Australian company Wave Swell Energy (WSE) now wants to take advantage of. The … Read more
Large container ships sometimes sail the oceans for weeks. Unlike a car, you can’t just equip them with a battery and an electric drive. Because there are not enough charging stations at sea. Experts therefore see a possible application for the fuel cell here. It converts hydrogen into electricity and uses it to power an … Read more
The energy company RWE likes to present itself green and sustainable in advertisements. For a while, the slogan “go ahead” was used for this. In fact, it is still one of the largest CO2 emitters in all of Europe. The group also has to catch up in the field of solar energy. RWE’s coal-fired power … Read more
At first glance, the idea sounds fantastic: if the entire Sahara were equipped with solar panels, the world’s energy needs could be covered four times. Researchers calculated that some time ago. The idea is also gaining traction because the area is largely inhospitable and uninhabited. So there would be no competition for space. The first … Read more
The Sahara is literally overflowing with energy: within a few hours, photovoltaic cells can harvest more electricity there than humanity uses in a year. Unfortunately, so far this energy is only available regionally, as an early 2000s project to import the electricity to Europe failed. Now British entrepreneur Simon Morrish wants to pick up the … Read more
The German-Spanish joint venture Siemens Gamesa recently made mostly negative headlines. Losses lined up on missed forecasts, so the boss had to be replaced twice. Meanwhile, majority shareholder Siemens Energy has lost patience and wants to take over the company completely. Then the costs have to come down. In fact, the entire industry is suffering … Read more
Experts and most politicians agree: renewable energy sources will have to be massively expanded in the coming years. Only in this way can we leave the era of fossil energy production behind us. But no matter how clear this basic orientation is, there are always discussions about detailed questions. This starts with the supposedly simple … Read more
Solar energy can now be produced very cheaply in many places in the world. Germany also wants to significantly increase its share in the electricity mix. However, in the production of the necessary solar panels, there is a risk of dependence on China which is not without concern. In principle, however, solar energy has the … Read more
When it comes to energy supply, Mecklenburg-Western Pomerania has long relied on the new Nord Stream 2 Baltic Sea pipeline. This is to transport gas from Russia to Northern Germany. The country even set up a so-called climate foundation to avoid potential US sanctions. With the Russian war of aggression in Ukraine, however, this approach … Read more
