Name a renewable energy source.

Solar energy is considered a renewable energy source because it is derived from the sun, which is an abundant and naturally replenishing resource. Unlike fossil fuels like coal and natural gas, which can be depleted and contribute to greenhouse gas emissions, solar energy harnesses sunlight using solar panels to generate electricity or heat, making it sustainable over the long term. Solar power can be used in various applications, from powering homes to large solar farms, and it does not produce pollutants, making it an environmentally friendly option.

In contrast, coal and natural gas are non-renewable resources that contribute to environmental degradation and climate change through carbon emissions when burned for energy. Nuclear energy, while it produces low emissions during electricity generation, relies on uranium, which is finite and poses other environmental and safety concerns. Thus, solar energy stands out as a clean, infinite, and widely available renewable energy source.
