rawan239 Working of wind turbines Wind turbines are a type of renewable energy that can be used to generate electricity. They work by converting the kinetic energy of the wind into mechanical energy, which is then used to turn a generator. The generator produces electricity, which can be used to power homes and businesses. Wind turbines … Read more
The International Solar Alliance (ISA) is a global alliance of 121 countries, most of which are located between the Tropics of Cancer and Capricorn. The ISA was founded in 2015 by India and France with the goal of promoting solar energy and reducing dependence on fossil fuels. The ISA has three main objectives: To promote … Read more
Luminescent Solar Concentrators (LSCs) Luminescent solar concentrators (LSCs) are a type of solar cell that uses a luminescent material to convert sunlight into electricity. LSCs are made up of a thin layer of luminescent material, such as a dye or a semiconductor, that is sandwiched between two electrodes. When sunlight hits the luminescent material, it … Read more
International Renewable Energy Agency (IRENA) The International Renewable Energy Agency (IRENA) is an intergovernmental organization that supports countries in their transition to a sustainable energy future. IRENA was established in 2009 and is headquartered in Abu Dhabi, United Arab Emirates. IRENA’s mission is to promote the widespread and sustainable use of renewable energy in the … Read more
Solar thermal technology is a type of renewable energy that uses the sun’s heat to generate electricity or heat water. Solar thermal systems can be used to provide hot water for homes and businesses, or to generate electricity for the grid. Solar thermal technology has been around for centuries, but it has only recently become … Read more
Concentrated solar power (CSP) is a type of solar power that uses the sun’s heat to generate electricity. CSP plants use mirrors or lenses to focus a large area of sunlight onto a small area, which heats a fluid to very high temperatures. This hot fluid is then used to generate steam, which drives a … Read more
Potential of solar energy in India India is one of the most promising countries for solar energy development. The country has a huge solar potential, with an estimated 5,000 trillion kWh of solar energy available per year. This is more than enough to meet the country’s current energy needs. In recent years, India has made … Read more
Solar Energy Solar energy is a type of renewable energy that comes from the sun. It is a clean and sustainable source of energy that can be used to generate electricity, heat water, and power vehicles. How does solar energy work? Solar energy works by converting sunlight into electricity or heat. This can be done … Read more
Photovoltaic Electricity Photovoltaic (PV) electricity is a type of solar energy that converts sunlight into electricity using semiconductors. PV cells are made of materials that allow electricity to flow when light hits them. When sunlight hits a PV cell, it knocks electrons loose from their atoms. These free electrons flow through the cell, creating an … Read more
