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 availability and uptake of green electricity in the United Kingdom has increased in the 21st century. There are a number of suppliers offering green electricity in the United Kingdom.

Sustainable distribution refers to any means of transportation / hauling of goods between vendor and purchaser with lowest possible impact on the ecological and social environment, and includes the whole distribution process from storage, order processing and picking, packaging, improved vehicle loadings, delivery to…

A bifacial solar cell (BSC) is a photovoltaic solar cell that can produce electrical energy from both front and rear side. In contrast, monofacial solar cells produce electrical energy only when photons are incident on their front side.

Solar power is an important source of electricity in India. Since the mid-2010s, India has increased its solar power significantly with the help of various government initiatives.

The use of solar energy began in Israel in the 1950s with the development by Levi Yissar of a solar water heater to address the energy shortages that plagued the new country. By 1967 around 5% of water of households were solar heated and 50,000 solar heaters had been sold.

Concentrated solar power (CSP), also called concentrating solar power or concentrated solar thermal, involves systems that collect solar heat for multiple purposes like cooking, desalination, or the generation of electric solar power, by using mirrors to concentrate a large area of sunlight toward a receiver. …

The Sudair PV IPP is a solar photovoltaic (PV) power plant located in Sudair Industrial City, Saudi Arabia.

Solar water heating (SWH) is heating water by sunlight, using a solar thermal collector. A variety of configurations are available at varying cost to provide solutions in different climates and latitudes.
