Passive solar building design
In passive solar building design, windows, walls, and floors are made to collect, store, reflect, and distribute solar energy, in the form of heat in the winter and reject solar heat in the summer. This is called passive solar design because, unlike active solar heating systems, it does not involve the use of…

The closure of the Strait of Hormuz, through which over 20% of the world's oil trade passes, and attacks on energy infrastructure in Iran and several Gulf Cooperation Council countries led to a large…
Solar power in Switzerland
Solar power in Switzerland has demonstrated consistent capacity growth since the early 2010s, influenced by government subsidy mechanisms such as the implementation of the feed-in tariff in 2009 and the enactment of the revised Energy Act in 2018. In 2025, solar power contributes nearly to 8 TWh of generation to the…
