Investigating Energy Resources & Transformations

What is an advantage of power plants powered by natural gas when compared to coal and oil?

• Natural gas generates more electricity when burned.

• Burning natural gas releases less pollution to the atmosphere.

• Natural gas requires long pipelines to reach power plants.

• Explosions are less likely when leaks occur in pipelines.
