Question: 1 / 400

What is one impact of using fossil fuels for energy?

They are renewable resources

They contribute to air pollution and climate change

Using fossil fuels for energy significantly contributes to air pollution and climate change due to the emissions produced when they are burned. Fossil fuels, such as coal, oil, and natural gas, release carbon dioxide (CO2) and other greenhouse gases into the atmosphere. These gases trap heat and lead to an increase in global temperatures, which is a primary cause of climate change. Additionally, the combustion of fossil fuels releases various pollutants, including sulfur dioxide, nitrogen oxides, and particulate matter, which degrade air quality and can harm human health and the environment. This impact is starkly contrasted with renewable energy sources, which typically produce little to no emissions.
