Question

which of the following energy sources contributes the least to climate change? choose 1 answer: a natural gas, which is burned to generate electricity b wind turbines, which harness wind energy to generate electricity c coal, which is combusted to produce steam for generating electricity

Explanation:

To determine which energy source contributes the least to climate change, we analyze each option:

• Option A: Natural gas is a fossil fuel. Burning it releases carbon dioxide ($\ce{CO_2}$) and other greenhouse gases, contributing to climate change.
• Option B: Wind turbines are a renewable energy source. They generate electricity by harnessing wind energy, which produces little to no greenhouse gas emissions during operation, so they have a minimal impact on climate change.
• Option C: Coal is a fossil fuel. Combusting coal releases large amounts of $\ce{CO_2}$, sulfur dioxide, and other pollutants, making it a major contributor to climate change.

Among these, wind turbines (Option B) contribute the least to climate change as they are a renewable, low - emission energy source.

Answer:

B. wind turbines, which harness wind energy to generate electricity
