Aerosols influence Earth’s climate both directly, by scattering and absorbing sunlight, and indirectly, by altering the reflectivity of clouds. (...) Albedo effect Albedo is the ability of a surface to reflect sunlight (solar radiation). Snow and ice have high albedo – much of the sunlight hitting surfaces covered with snow and ice bounces back. (...) Therefore, snow and ice which are covered in soot from pollution no longer reflect sunlight, but absorb it and so melting increases.

Too little Sun impacts our mood and well-being and increases the risk of Vitamin D deficiency. Overexposure to sunlight causes harmful effects on the skin, eyes, and immune system. (...) This influence is seen in seasonal variations of psychiatric phenomena related to exposure to longer and shorter sunlight hours, especially mood and anxiety symptoms, as well as suicide.  Sunlight is also necessary for the production of vitamin D, which helps to regulate the amount of calcium and phosphate in the body, both are needed to keep bones and teeth healthy.

Passive solar techniques include orienting a building to the Sun, selecting materials with favourable thermal mass or light dispersing properties, and designing spaces that naturally circulate air. The solar photovoltaic system consists of an arrangement of several components, including solar panels to absorb and convert sunlight into electricity. Concentrated Solar Power (CSP) systems concentrate direct sunlight to reach high temperatures. This heat can then be used to power a steam turbine which drives a generator. Solar water heating is the conversion of sunlight into heat for water heating using a solar thermal collector.

The Sun and seasons The tilt of Earth’s axis relative to its orbit around the Sun determines the duration of daylight and the amount of sunlight received at any latitude, ranging from polar to equatorial regions. (...) When it is the summer solstice in the Northern Hemisphere, the areas north of the Arctic circle receive sunlight for a full 24 hours, while areas south of the Antarctic circle have a full day of total darkness. (...) During the summer solstice the Northern Hemisphere of Earth is tilted towards the sun resulting in increased sunlight and warmer temperatures, this results in continuous daylight in far northern countries such as Iceland and Norway.

(...) To calculate how much electricity a proposed solar energy installation will produce, they need to know how much sunlight will be available on sunny days and cloudy days, or on short winter days versus long summer days.

Renewable energy is energy derived from natural sources that are replenished at a higher rate than they are consumed. Sunlight and wind, for example, are such sources that are constantly being replenished. (...) Solar technologies convert sunlight into electrical energy either through photovoltaic panels or through mirrors that concentrate solar radiation.
