Question

Quizplus · Accepted Answer

Better energy efficiency would reduce the amount of energy needed to perform certain tasks, ultimately reducing the production of greenhouse gases and other pollutants. This approach would have the biggest impact on improving the quality of the environment. Hydrogen gas and clean biomass are also clean energy sources, but their production and deployment can still cause environmental damage. Wind energy is clean and renewable, but it requires large amounts of land, and the turbines can sometimes negatively impact wildlife habitats.
