A white person's right hand is touching the meter at the point where the numbers are going up, perhaps to convey the idea that the person is worried about their gas consumption. There is a thick layer of dust on the meter.

The place of natural gas in a clean energy future is hotly debated. But, there is a simple answer to whether natural gas is renewable.

Hydrogen is a fuel source that is a possible alternative to fossil fuels. It can be used in fuel cells and to create heat, and its only by-product is water, meaning it does not release any greenhouse gases when burned.
