  3. Solar activity and climate - Wikipedia

    en.wikipedia.org/wiki/Solar_activity_and_climate

    The finding that solar activity was approximately the same in cycles 14 and 24 applies to all solar outputs that have, in the past, been proposed as a potential cause of terrestrial climate change and includes total solar irradiance, cosmic ray fluxes, spectral UV irradiance, solar wind speed and/or density, heliospheric magnetic field and its ...

  4. Renewable energy debate - Wikipedia

    en.wikipedia.org/wiki/Renewable_energy_debate

    Variability inherently affects solar energy, as the production of electricity from solar sources depends on the amount of light energy in a given location. Solar output varies throughout the day, the seasons, with cloud cover and by latitude on the globe. Windblown sand erodes glass in dry climates, protective layers add expenses.

  5. Solar energy - Wikipedia

    en.wikipedia.org/wiki/Solar_energy

    Solar energy is the radiant energy from the Sun's light and heat, which can be harnessed using a range of technologies such as solar electricity, solar thermal energy (including solar water heating) and solar architecture.

  6. Ground level enhancement - Wikipedia

    en.wikipedia.org/wiki/Ground_level_enhancement

    The method by which solar flares and coronal mass ejections (CMEs) produce such high-energy particles is still uncertain, with some studies suggesting that they are produced mostly by a CME shock wave, by strong flare events or some combination, or related to the connection between the active solar region and the magnetic field of the Earth.

  7. Solar phenomena - Wikipedia

    en.wikipedia.org/wiki/Solar_phenomena

    A solar flare is a sudden flash of brightness observed over the Sun's surface or the solar limb, which is interpreted as an energy release of up to 6 × 10 25 joules (about a sixth of the total Sun's energy output each second or 160 billion megatons of TNT equivalent, over 25,000 times more energy than released from the impact of Comet ...

  9. Photovoltaic effect - Wikipedia

    en.wikipedia.org/wiki/Photovoltaic_effect

    The first demonstration of the photovoltaic effect, by Edmond Becquerel in 1839, used an electrochemical cell. He explained his discovery in Comptes rendus de l'Académie des sciences, "the production of an electric current when two plates of platinum or gold immersed in an acid, neutral, or alkaline solution are exposed in an uneven way to solar radiation."
