What are the 3 main uses of solar energy?
The most commonly used solar technologies for homes and businesses are solar photovoltaics for electricity, passive solar design for space heating and cooling, and solar water heating. Businesses and industry use solar technologies to diversify their energy sources, improve efficiency, and save money.
What do you mean by solar energy?
Solar energy is defined as the transformation of energy that is present in the sun and is one of the renewable energies. Once the sunlight passes through the earth’s atmosphere, most of it is in the form of visible light and infrared radiation. Solar cell panels are used to convert this energy into electricity.
Why is solar energy useful?
Solar power systems derive clean, pure energy from the sun. Installing solar panels on your home helps combat greenhouse gas emissions and reduces our collective dependence on fossil fuel. Traditional electricity is sourced from fossil fuels such as coal and natural gas. Renewable energy also improves public health.
