Solar energy is the energy that is generated from the sun. It is a renewable energy source, that it can be used over and over again without running out.
The Clean, Renewable, and Affordable Energy Source of the Future
Solar energy is the energy that is generated from the sun. It is a renewable energy source, meaning that it can be used over and over again without running out. Solar energy is also clean energy, meaning that it does not produce greenhouse gases or other pollutants.
There are two main types of solar energy:
- Photovoltaic (PV) solar energy converts sunlight directly into electricity. PV cells are made of semiconductor materials, such as silicon, that generate electricity when sunlight hits them. PV cells are used in solar panels, which can be installed on roofs or in other sunny locations.
- Solar thermal energy uses the sun's heat to generate electricity or heat water. Solar thermal collectors use mirrors or lenses to focus sunlight onto a heat transfer fluid, which can then be used to generate steam or heat water. Solar thermal power plants can generate electricity on a large scale, while solar thermal water heaters can be used for domestic hot water or space heating.
Solar energy is a growing source of energy around the world. In 2021, solar power generated about 2.9% of the world's electricity. Solar energy is expected to continue to grow in the coming years, as it becomes more affordable and efficient.
Industry applications of solar:
A single photovoltaic cell contains semiconductors that can convert sunlight into electricity. As photovoltaic cells only generate a limited amount of energy, numerous cells are connected together to create a single solar panel.Read More
Some of the benefits of using solar energy
Reduces reliance on fossil fuels
Lumber is the most common wood product. It is made from sawed logs and is used to build houses, furniture, and other structures.
Clean and renewable
Plywood is made from thin layers of wood that are glued together. It is stronger and more stable than lumber and is used for a variety of applications, including flooring, subflooring, and cabinetry.
Paper is made from wood pulp. It is used for a variety of purposes, including writing, printing, and packaging.
