Wind energy
Explanation
Wind energy is considered intermittent because it depends on wind conditions, which can vary significantly.
Common mistake
Renewable energy is always pollution‑free
Students often think that renewable energy sources such as solar, wind or hydroelectricity produce no environmental impact, ignoring issues like land use, habitat disruption or resource extraction.
Explain that while renewables emit little or no greenhouse gases during operation, they can still cause environmental impacts—for example, large solar farms require land and materials, wind turbines can affect bird and bat populations, and hydroelectric dams can alter river ecosystems and displace communities. Emphasise that all energy resources have some environmental footprint, but renewables generally have lower long‑term impacts compared with fossil fuels and nuclear energy.
