In Canada, the use of solar energy to generate electricity and heat is growing quickly and is helping reduce pollution related to energy production. Despite Canada''s cold
The amount of sunlight that strikes the earth's surface in an hour and a half is enough to handle the entire world's energy consumption for a full year. Solar technologies convert sunlight into electrical energy either through photovoltaic (PV) panels or through mirrors that concentrate solar radiation.
Solar energy is any type of energy generated by the sun. Solar energy is created by nuclear fusion that takes place in the sun. Fusion occurs when protons of hydrogen atoms violently collide in the sun’s core and fuse to create a helium atom. This process, known as a PP (proton-proton) chain reaction, emits an enormous amount of energy.
An electric grid with lots of solar power must pair it with other technologies for reliability: energy sources like hydropower that can be powered up and down at will, energy storage (like batteries) to save up solar energy when it’s plentiful, and/or long-distance transmission to move electricity from the sunniest spots to where it’s needed.
There are several ways to turn sunlight into usable energy, but almost all solar energy today comes from “solar photovoltaics (PV).” Solar PV relies on a natural property of “semiconductor” materials like silicon, which can absorb the energy from sunlight and turn it into electric current.
In most places on Earth, sunlight’s variability makes it difficult to implement as the only source of energy. The Agua Caliente Solar Project, in Yuma, Arizona, United States, is the world's largest array of photovoltaic panels. Agua Caliente has more than five million photovoltaic modules, and generates more than 600 gigawatt-hours of electricity.
There are different ways of capturing solar radiation and converting it into usable energy. The methods use either active solar energy or passive solar energy. Active solar technologies use electrical or mechanical devices to actively convert solar energy into another form of energy, most often heat or electricity.
