  2. Solar energy conversion - Wikipedia

    en.wikipedia.org/wiki/Solar_energy_conversion

    Many steam generation systems have adapted to using sunlight as a primary source for heating feed water, a development that has greatly increased the overall efficiency of boilers and many other types of waste heat recovery systems. Solar cookers use sunlight for cooking, drying and pasteurization. Solar distillation is used for water treatment ...

  3. Photosynthetic efficiency - Wikipedia

    en.wikipedia.org/wiki/Photosynthetic_efficiency

    68% of the used energy is lost in conversion into d-glucose; 35–45% of the glucose is consumed by the leaf in the processes of dark and photo respiration; Stated another way: 100% sunlight → non-bioavailable photons waste is 47%, leaving; 53% (in the 400–700 nm range) → 30% of photons are lost due to incomplete absorption, leaving

  4. Outline of solar energy - Wikipedia

    en.wikipedia.org/wiki/Outline_of_solar_energy

    Solar power – the conversion of sunlight into electricity, either directly using photovoltaics (PV), or indirectly using concentrated solar power (CSP).. Active solar – technologies are employed to convert solar energy into another more useful form of energy (for example, to heat or electrical energy).

  5. Photosynthesis - Wikipedia

    en.wikipedia.org/wiki/Photosynthesis

    Photosynthesis (/ ˌ f oʊ t ə ˈ s ɪ n θ ə s ɪ s / FOH-tə-SINTH-ə-sis) [1] is a system of biological processes by which photosynthetic organisms, such as most plants, algae, and cyanobacteria, convert light energy, typically from sunlight, into the chemical energy necessary to fuel their metabolism.

  6. Solar energy - Wikipedia

    en.wikipedia.org/wiki/Solar_energy

    The molten salts then transfer their heat in a heat exchanger to water, generating superheated steam, which feeds a turbine that transforms the kinetic energy of the steam into electric energy using the Rankine cycle. [60] In this way, the Cerro Dominador plant is capable of generating around 110 MW of power. [61]

  7. Solar thermal energy - Wikipedia

    en.wikipedia.org/wiki/Solar_thermal_energy

    Heat gain is the heat accumulated from the sun in the system. Solar thermal heat is trapped using the greenhouse effect; the greenhouse effect in this case is the ability of a reflective surface to transmit short wave radiation and reflect long wave radiation. Heat and infrared radiation (IR) are produced when short wave radiation light hits ...

    In July, divers with a research team descended into tropical waters off southwest Puerto Rico, along a reef in La Parguera Marine Preserve. Schools of bar jack fish swam through, rays of sun ...

  9. Sunlight - Wikipedia

    en.wikipedia.org/wiki/Sunlight

    [4] Sunlight is a key factor in photosynthesis, the process used by plants and other autotrophic organisms to convert light energy, normally from the Sun, into chemical energy that can be used to synthesize carbohydrates and fuel the organisms' activities. Daylighting is the natural lighting of interior spaces by admitting sunlight.
