  2. Solar wind - Wikipedia

    en.wikipedia.org/wiki/Solar_wind

    The solar wind is observed to exist in two fundamental states, termed the slow solar wind and the fast solar wind, though their differences extend well beyond their speeds. In near-Earth space, the slow solar wind is observed to have a velocity of 300–500 km/s , a temperature of ~ 100 kilokelvin and a composition that is a close match to the ...

  3. Hybrid power system - Wikipedia

    en.wikipedia.org/wiki/Hybrid_power

    Hybrid power are combinations between different technologies to produce power. In power engineering, the term 'hybrid' describes a combined power and energy storage system. [1] Examples of power producers used in hybrid power are photovoltaics, wind turbines, Wind-hydrogen system and various types of engine-generators – e.g. diesel gen-sets. [2]

  4. Solar System - Wikipedia

    en.wikipedia.org/wiki/Solar_System

    Solar wind from the Sun created the heliosphere and swept away the remaining gas and dust from the protoplanetary disc into interstellar space. [23] Following the dissipation of the protoplanetary disk, the Nice model proposes that gravitational encounters between planetisimals and the gas giants caused each to migrate into different orbits ...

  5. Wind power - Wikipedia

    en.wikipedia.org/wiki/Wind_power

    Wind power is the use of wind energy to generate useful work. Historically, wind power was used by sails, windmills and windpumps, but today it is mostly used to generate electricity. This article deals only with wind power for electricity generation. Today, wind power is generated almost completely with wind turbines, generally grouped into ...

  6. Solar energy - Wikipedia

    en.wikipedia.org/wiki/Solar_energy

    Electricity production. Solar power, also known as solar electricity, is the conversion of energy from sunlight into electricity, either directly using photovoltaics (PV) or indirectly using concentrated solar power. Solar panels use the photovoltaic effect to convert light into an electric current. [63]

  7. Renewable energy - Wikipedia

    en.wikipedia.org/wiki/Renewable_energy

    Renewable energy (or green energy) is energy from renewable natural resources that are replenished on a human timescale. The most widely used renewable energy types are solar energy, wind power, and hydropower. Bioenergy and geothermal power are also significant in some countries. Some also consider nuclear power a renewable power source ...
