Solar energy is radiant light and heat from the Sun that is harnessed using a range of technologies such as solar power to generate electricity, solar thermal energy (including solar water heating), and solar architecture. It is an essential source of renewable energy, and its technologies are broadly characterized as either passive solar or active solar depending on how they capture and distribute solar energy or convert it into solar power. Active solar techniques include the use of photovoltaic systems, concentrated solar power, and solar water heating to harness the energy. Passive solar techniques include orienting a building to the Sun, selecting materials with favorable thermal mass or light-dispersing properties, and designing spaces that naturally circulate air.

 

How Does Solar Work?

Solar energy works by converting sunlight into electricity or heat. There are two main types of solar technologies: photovoltaic (PV) and solar thermal.

 

 

Why is solar energy important?

As a renewable source of power, solar energy has an important role in reducing greenhouse gas emissions and mitigating climate change, which is critical to protecting humans, wildlife, and ecosystems.

What are the 5 uses of solar energy?

The five main uses of solar energy are solar electricity, solar water heating, solar heating, solar ventilation and solar lighting. There are more uses for solar energy, but home solar installation and businesses typically use solar energy for these purposes.
