Question

Article on topic solar power in 120 words please

Answer 1

Article shared by Solar energy is the energy received by the earth from the sun that is converted into thermal or electrical energy.Solar energy influences Earth’s climate and weather and sustains life. Although solar energy only provides 0.15% of the world’s power, experts believe that sunlight has the potential to supply 5000 time as much energy as the world currently consumes.Broadly speaking, solar energy is a term for describing a range of methods for obtaining energy from the sun. For instance, wind, biomass and hydropower are all forms of solar energy.Wind develops through lows and highs in temperature. Wind drives waves. Rainfall, created by sun-warmed evaporated water feeds the rivers that are sources of hydro power. Fossil fuels are also forms of stored solar energy. Coal, oil and gas formed hundreds of millions of years ago from decomposed plant matter. Plant matter that grew by aid of the sun.

Answer 2

Solar power

This article is about generation of electricity using solar energy. For other uses of solar energy, see Solar energy.

Not to be confused with Solar luminosity.

Potential of solar energy. The small black dots show land area required to replace the world primary energy supply with solar power.

Solar power is the conversion of energy from sunlight into electricity, either directly using photovoltaics (PV), indirectly using concentrated solar power, or a combination. Concentrated solar power systems use lensesor mirrors and tracking systems to focus a large area of sunlight into a small beam. Photovoltaic cells convert light into an electric current using the photovoltaic effect.[1]

Photovoltaics were initially solely used as a source of electricity for small and medium-sized applications, from the calculatorpowered by a single solar cell to remote homes powered by an off-grid rooftop PV system. Commercial concentrated solar power plants were first developed in the 1980s. The 392 MW Ivanpah installation is the largest concentrating solar power plant in the world, located in the Mojave Desert of California.

As the cost of solar electricity has fallen, the number of grid-connected solar PV systemshas grown into the millions and utility-scale solar power stations with hundreds of megawatts are being built. Solar PV is rapidly becoming an inexpensive, low-carbon technology to harness renewable energy from the Sun. The current largest photovoltaic power station in the world is the 850 MW Longyangxia Dam Solar Park, in Qinghai, China.

The International Energy Agency projected in 2014 that under its "high renewables" scenario, by 2050, solar photovoltaics and concentrated solar power would contribute about 16 and 11 percent, respectively, of the worldwide electricity consumption, and solar would be the world's largest source of electricity. Most solar installations would be in China and India.[2] As of 2016, solar power provided just 1% of total worldwide electricity production but was growing at 33% per annum.
