Мировой рекорд эффективности солнечных батарей
A new world record has been achieved for the efficiency of tandem solar cells. With a perovskite silicon solar cell researchers at Helmholtz Berlin have achieved an efficiency of 29.8 percent for the first time. Like silicon, the mineral perovskite is found in the Earth’s crust, but is now also produced artificially. Due to their physical properties, […]
Основные итоги Всемирной климатической конференции COP26 в Глазго
The COP26 world climate conference has come to an end in Glasgow. In its final document, the international community agreed on a wide range of measures and declarations of intent. Reactions to the results of the conference differ widely. Some established politicians speak of a success, while environmental activists describe the results as insufficient. “The […]
ГМО для производства зеленой энергии
Solar energy is a good thing, but there is just one “but”: With current batteries, for example, it is difficult to store the energy that accumulates during production peaks. It would take a tool to flatten the sinusoidal production curve. In the article “N-Butanol production by Rhodopseudomonas palustris TIE-1” in the journal Communications Biology, a […]
Как сократить чистые выбросы до нуля к 2050 году?
The International Energy Agency’s (IEA) World Energy Outlook (WEO) was all about the big picture this year: ahead of the start of the COP26 global climate conference in Glasgow, the IEA presented its “Net Zero 2050 Roadmap” on how net emissions can be reduced to zero by 2050 so that the agreed 1.5-degree target is […]
Отрицательные выбросы благодаря технологиям улавливания и хранения углерода
Just a few years ago, the issue of negative emissions through CCS (“Carbon Capture and Storage”) was little discussed for Germany’s strategy in reducing its greenhouse gas emissions. However, with the agreement to achieve carbon neutrality in Germany by 2045, a key problem emerged: even with an optimal energy economy, based on renewable energies, residual […]
Законопроект об обязательной установке солнечных батарей на крышах в Германии
In some German states, including Baden-Württemberg and Berlin, solar roofs will be mandatory for commercial buildings as early as January 2022. Now, a draft law of the new federal government also provides for the nationwide installation obligation of solar systems on public and private buildings in the coming year. The law is to apply both […]
Более 100 стран обязуются защищать леса
At the COP26 International Climate Change Conference in Glasgow, more than 100 countries pledged to stop deforestation by 2030. Those countries with the world’s largest forest areas – Brazil, Canada, Russia, Colombia and China – also pledged to comply with the agreement. To this end, the states intend to provide 12 billion U.S. dollars, with […]
Constant PV additions – significant differences in market segments
According to the Federal Network Agency in Germany, in the first eight months of 2021, i.e. from January to August 2021 – excluding large installations based on Power Purchase Agreements (PPAs), which would still have to be added – around 3.62 gigawatts of new PV capacity has already been installed in Germany, an increase of […]
Фотоэлектрические системы для крыш грузовиков
Unlike cars, which have hardly any surface area for photovoltaics, installing PV modules on trucks can be worthwhile. The Fraunhofer Institute for Solar Energy Systems ISE has now built Germany’s first solar truck. The particularly lightweight PV modules for the vehicle were developed by the Fraunhofer Institute for Transportation and Infrastructure Systems IVI together with partners from industry. The […]
Системы отопления в Германии с применением фотовольтаики
With rising gas prices and the emergence of new environmentally friendly technologies, gas heating is declining in Germany relatively and will increasingly be displaced by the combination of photovoltaic systems with heat pumps. It is also high time for such solutions, with very few climate-relevant emissions, since heating contributes to about a quarter of Germany’s […]
