Which energy source is considered sustainable?

Which energy source is considered sustainable?

• A. Wind
• B. Coal
• C. Oil
• D. Natural Gas

Answer: (A)

Sustainability in energy means choosing sources that can meet our needs far into the future without exhausting resources or causing unacceptable environmental harm. Wind energy uses a free, inexhaustible resource—the movement of air—so it can keep producing electricity as long as wind continues. Its operation emits little to no greenhouse gases, reducing air pollution and climate impact compared with fossil fuels. In contrast, coal, oil, and natural gas are fossil fuels that exist in finite quantities and release significant greenhouse gases and pollutants when burned, making them unsustainable choices for long-term use. Because of the combination of abundant supply and low emissions during operation, wind is the sustainable option.
