When the sun shines or the wind blows, solar panels and wind turbines gather their energy to generate electricity, powering homes and businesses. And these renewable sources of electricity support peoples’ lives without emitting the planet-heating gases that come from burning fossil fuels like coal, oil, and gas.
Wind is a form of solar energy caused by a combination of three concurrent events: The rotation of the earth. Wind flow patterns and speeds vary greatly across the United States and are modified by bodies of water, vegetation, and differences in terrain.
Solar energy is harnessed from the Sun using solar panels. As long as there is sunlight, we can use solar energy. Solar panels are made out of photovoltaic cells and they absorb energy from the Sun. Unlike many other renewable energy sources, solar energy doesn’t require a turbine to generate electricity.
Wind is air that is in motion, and the kinetic energy of wind is the renewable energy. How wind energy works: 1. When the wind blows, it transfers some of its kinetic energy to the blades. 2. The blades of the turbine spin around a rotor, which drives the turbine. 3. The turbine turns the generator, which generates electricity.
And when air moves quickly, in the form of wind, those particles are moving quickly. Motion means kinetic energy, which can be captured, just like the energy in moving water can be captured by the turbine in a hydroelectric dam. In the case of a wind-electric turbine, the turbine blades are designed to capture the kinetic energy in wind.
The generator turns that rotational energy into electricity. At its essence, generating electricity from the wind is all about transferring energy from one medium to another. Wind power all starts with the sun. When the sun heats up a certain area of land, the air around that land mass absorbs some of that heat.
