What is an example of a renewable energy source?

Solar energy is an example of a renewable energy source because it is derived from the Sun, which is a natural and virtually inexhaustible resource. The Sun's energy is continuously available and can be harnessed through various technologies, such as solar panels, to generate electricity and heat. Unlike fossil fuels, which can deplete over time, solar energy can be captured repeatedly without diminishing its availability. This makes it a sustainable option for meeting energy needs while contributing to lower greenhouse gas emissions and reducing dependency on non-renewable energy sources.

In contrast, coal and natural gas are considered non-renewable energy sources because they are finite resources formed over millions of years and will eventually be exhausted due to extensive extraction and usage. Nuclear energy, while it is low in carbon emissions during operation, relies on uranium and other radioactive materials that, despite being more abundant than fossil fuels, are also not renewable on a human timescale. Thus, solar energy distinctly stands out as a renewable alternative, showcasing the importance of sustainable energy in combating climate change and promoting environmental health.
