How is solar energy utilized? Discover the most popular applications of solar energy and what the future holds for its use.
The sun is essential for all life on Earth, providing energy that can be harnessed in various ways. It generates two main energy types—light and heat—that we can utilize for diverse activities, from powering photosynthesis in plants to generating electricity through photovoltaic (PV) cells and heating water and food.
Let’s explore 51 common applications of solar energy in our everyday lives.
1. Solar Electricity
Solar electricity has gained significant traction in recent years. As the costs of solar panels continue to decline and awareness of their financial and environmental benefits grows, more homeowners and businesses are adopting solar energy. While it only accounted for 2.8% of electricity generation in the U.S. in 2021, solar power is rapidly expanding, allowing users to generate their own electricity and contribute excess power to the grid.
2. Solar Batteries
A solar battery connects to your solar energy system, enabling you to utilize solar power during nighttime or emergencies. Many homeowners opt for solar battery systems to go off-grid, depending on factors like daily energy usage, sunlight availability, panel efficiency, and battery capacity.
