1. select all that apply.

which three examples are of clean energy sources that help reduce air pollution?

• wind turbines
• coal
• solar panels

Explanation:

Question 11

Carbon capture and storage (CCS) technology is mainly used to capture carbon dioxide (CO₂) from large - scale emission sources. Power plants, especially those that burn fossil fuels (like coal - fired power plants), are major emitters of CO₂. Rivers are water bodies and do not emit significant amounts of CO₂. Homes have relatively small - scale emissions compared to power plants, and forests are carbon sinks (they absorb CO₂ rather than being a source of emission that needs to be captured from). So the correct source to capture CO₂ from is power plants.

Clean energy sources are those that produce little to no air pollution during operation. Wind turbines generate electricity using wind energy, and there is no air pollution from their operation. Solar panels convert solar energy into electricity, and their operation also does not produce air pollution. Hydropower uses the energy of flowing water to generate electricity, and it is a clean energy source. Coal is a fossil fuel, and burning coal releases a large amount of pollutants like sulfur dioxide, nitrogen oxides, and particulate matter into the air. Natural gas, although cleaner than coal, still produces some pollutants when burned. So the three clean energy sources are wind turbines, solar panels, and hydropower.

Answer:

D. power plants
