Natural gas (in its gaseous state) may not be "renewable", but it is still relatively plentiful, cheap, clean and can be stored. Natural gas consists primarily of methane, and is used to generate about a quarter of all the electricity generated in the United States. Although natural gas is not as clean as wind and water, it will continue to be seen as a viable energy source readily available in the United States. Natural gas boils water, which makes steam, which turns electric generators.

Natural Gas Pipelines.

Williams operates three natural gas transmission pipelines. Together, these pipelines map deliver approximately 14 percent of the natural gas consumed in the United States.

Williams Natural Gas Pipelines.

Gas Transmission Northwest, also known as GTN, has been transporting natural gas to Western energy markets for more than 40 years. GTN has been asked by Portland General Electric to seek a permit from the Federal Energy Regulatory Commission to construct a natural gas pipeline lateral in north-central Oregon to serve a proposed electric generation facility.

Natural Gas Pipelines.

Mist Oregon not only contains buried Natural Gas, it also contains a natural gas storage capability. The Mist Gas Fields have been developed into the only producing natural gas site in Oregon. The gas is found in relatively shallow pockets (2200 feet) with a solid dome above it and salt water below it. The geology is also ideal for gas storage. It is controlled by NW Natural (formerly Northwest Natural Gas) and is connected by several pipelines, including a 16-inch and a 24-inch pipeline along the Nehalem Highway.

St John's Landfill (now closed)

Decaying waste produces methane gas, which is the primary ingredient in Natural Gas. But it poses risk of fire and explosion in closed landfills, like St. Johns Landfill St John's Landfill Map.

Metro installed a network of about 188 wells and trenches and 16 miles of pipeline across the St. John's landfill (right) when the facility was closed. The methane gas is drawn to a compressor station from where it is pushed through two miles of pipeline to the Ash Grove Cement Company, where it is used to fuel lime kilns.

Three years ago NW Natural launched Smart Energy, a voluntary offset program to reduce carbon footprints, while assisting dairies in turning cow waste into a renewable fuel.

The Climate Trust, a local nonprofit developes offset projects. They helped fund three regional biodigesters – two in Washington and one in Oregon. Pipes deliver manure to a digester tank, which captures and combusts the methane in a generator to make renewable electricity.

Portland Superfund Sites

The initial focus of the study was the heavily industrialized area between Swan and Sauvie Islands. The investigation area currently extends from the Columbia Slough to the Fremont Bridge.

More than a century of historical industrial use has resulted in Willamette River sediments being contaminated with many hazardous substances, such as heavy metals, polychlorinated biphenyls (PCBs), polynuclear aromatic hydrocarbons (PAH), dioxin/furans, and pesticides.

Bend-based InEnTec has recognized for its waste gasification system, which the company calls the Plasma Enhanced Melter that transforms industrial wastes into a gas that can be used to produce electricity.

Hydraulic fracturing

Hydraulic fracturing (fracking) has revolutionized the potential extraction and recovery of fossil fuels. The energy from the injection of a highly-pressurized fracking fluid creates new channels in the rock which can dramatically increase the release petroleum, natural gas and shale gas.

Fracking has resulted in a 180 degree change of attitude regarding importing Natural Gas (in its liquid state). Now it's all about EXPORTING Liquified Natural Gas.

Proponents of fracking point to the vast amounts of formerly inaccessible hydrocarbons the process can extract.

Detractors say it can contaminate ground water, risks air quality, risks migration of gases and hydraulic fracturing chemicals to the surface, and has potential health effects like cancer.

Shale Gas Map

Shale gas refers to natural gas that is trapped within shale formations. The combination of horizontal drilling and hydraulic fracturing has allowed access to large volumes of shale gas that were previously uneconomical to produce. The production of natural gas from shale formations has rejuvenated the natural gas industry in the United States.

According to the International Energy Agency, the global use of natural gas will rise by more than 50% compared to 2010 levels, and account for over 25% of world energy demand in 2035.
