Natural gas and propane offer significant opportunities for major reductions in carbon emissions compared to electric and oil equipment on a full fuel cycle ("source-to-site") basis.
Historically, this fact has not been generally recognized by policymakers, regulators, customers, and environmental groups. Large increases in U.S. carbon dioxide emissions are being driven in the residential and commercial sectors by electricity usage.
The public perception is often that natural gas and propane are part of the carbon problem, rather than part of the solution. But natural gas and propane have the ability to provide source energy savings and carbon emissions reductions in addition to the savings that can be achieved by using renewable solar thermal and biogas energy solutions. Furthermore, natural gas has the potential to offer life cycle cost savings over comparable electric or oil systems.
