24 seconds: Active solar energy is a common source of renewable energy that is cleaner and more cost effective than fossil fuels. Active solar energy uses mechanical systems, such as photovoltaic cells, to store and convert energy from the sun into electricity or heat. These systems can be easily installed, requiring little to no maintenance, and will provide for years of solar benefits. This energy can be produced every day, even on cloudy days, and the use of the storage units within the system allows for the excess solar energy to be stored for later use. While there are extremely low levels of CO2 and other greenhouse gases being emitted during the installation process, no air pollutants are released afterwards. The reliance on fossil fuels and non-renewable resources can lessen as we convert to cleaner energy sources, creating a cleaner environment
