Natural gas, or methane, is one of the cleanest, safest and most useful forms of energy. It has a number of distinct advantages:

• Simple chemical make-up: one atom of carbon and four atoms of hydrogen (CH4).
• Burns cleanly: with the highest hydrogen-to-carbon ratio of any hydrocarbon, natural gas produces less greenhouse gases and particulate matter (i.e. soot).  
• Plentiful resource: natural gas is abundant in North America and worldwide. Biomethane (renewable natural gas) produced from landfill gas, food and animal wastes, also contributes to this abundant supply of clean, renewable energy.
