Comparing Greenhouse Gas Impacts from Domestic Coal and Imported Natural Gas Electricity Generation in China

Comparative life-cycle air emissions of coal, domestic natural gas, LNG, and SNG for electricity generation.

The U.S. Department of Energy (DOE) estimates that in the coming decades the United States' natural gas (NG) demand for electricity generation will increase. Estimates also suggest that NG supply will increasingly come from imported liquefied natural gas (LNG). Additional supplies of NG could come domestically from the production of synthetic natural gas (SNG) via coal gasification-methanation....

Greenhouse Gas Analysis of Electricity Generation Systems

All renewable energy systems make some contribution to climate change. This is due to the emission of greenhouse gases from the fossil fuels combusted for their construction, and as back-up energy during their operation. Accurate calculation of greenhouse gas emissions per kilowatt hour of electricity is difficult, but is an important part of policy making and planning. Calculation methodologie...

The Domestic Natural Gas Shortage in China

Understanding Greenhouse Gas Emissions from Unconventional Natural Gas Production

Natural gas comprises almost one-fourth of all energy used in the U.S. New technologies, sometimes referred to as “unconventional” have enabled the production of more natural gas and have expanded domestic energy reserves. Natural gas is generally recognized as a clean-burning fuel source, producing less greenhouse gas (GHG) emissions per quantity of energy consumed than either coal or oil. How...
