Coalbed Methane In The United States
The 2017 production of coalbed methane in the United States was 0.98 trillion cubic feet (TCF), 3.6 percent of all US dry gas production that year. The 2017 production was down from the peak of 1.97 TCF in 2008. Most coalbed methane production came from the Rocky Mountain states of Colorado, Wyoming, and New Mexico. Coalbed methane reserve estimates vary; however a 1997 estimate from the U.S. Geological Survey predicts more than of methane within the US. At a natural gas price of US$6.05 per million Btu (US$5.73/GJ), that volume is worth US$4.37 trillion. At least of it is economically viable to produce. The EIA reports 2017 reserves at 11,878 billion cubic feet (BCF) or 11.878 trillion cubic feet, which at a current market price of US $2.97 as of May 14, 2021, are worth approximately $36.2 Billion USD. History Coalbed methane grew out of venting methane from coal seams. Some coal beds have long been known to be "gassy," and as a safety measure, boreholes were drilled into ...

Total Dissolved Solids
Total dissolved solids (TDS) is a measure of the dissolved combined content of all inorganic and organic substances present in a liquid in molecular, ionized, or micro-granular ( colloidal sol) suspended form. TDS concentrations are often reported in parts per million (ppm). Water TDS concentrations can be determined using a digital meter. Generally, the operational definition is that the solids must be small enough to survive filtration through a filter with 2-micrometer (nominal size, or smaller) pores. Total dissolved solids are normally discussed only for freshwater systems, as salinity includes some of the ions constituting the definition of TDS. The principal application of TDS is in the study of water quality for streams, rivers, and lakes. Although TDS is not generally considered a primary pollutant (e.g. it is not deemed to be associated with health effects), it is used as an indication of aesthetic characteristics of drinking water and as an aggregate indicator of the ...

Coal In The United States
Coal mining is an industry in transition in the United States. Production in 2019 was down 40% from the peak production of in 2008. Employment of 43,000 coal miners is down from a peak of 883,000 in 1923. Generation of electricity is the largest user of coal, being used to produce 50% of electric power in 2005 and 27% in 2018. The U.S. is a net exporter of coal. U.S. coal exports, for which Europe is the largest customer, peaked in 2012. In 2015, the U.S. exported 7.0 percent of mined coal. According to the U.S. Energy Information Administration (EIA), in 2015, Wyoming, West Virginia, Kentucky, Illinois, and Pennsylvania produced about , representing 71% of total coal production in the United States. In 2015, four publicly traded US coal companies filed for Chapter 11 bankruptcy protection, including Patriot Coal Corporation, Walter Energy, and the fourth-largest Alpha Natural Resources. By January 2016, more than 25% of coal production was in bankruptcy in the United S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Methane
Methane ( , ) is a chemical compound with the chemical formula (one carbon atom bonded to four hydrogen atoms). It is a group-14 hydride, the simplest alkane, and the main constituent of natural gas. The relative abundance of methane on Earth makes it an economically attractive fuel, although capturing and storing it poses technical challenges due to its gaseous state under normal conditions for temperature and pressure. Naturally occurring methane is found both below ground and under the seafloor and is formed by both geological and biological processes. The largest reservoir of methane is under the seafloor in the form of methane clathrates. When methane reaches the surface and the atmosphere, it is known as atmospheric methane. The Earth's atmospheric methane concentration has increased by about 150% since 1750, and it accounts for 20% of the total radiative forcing from all of the long-lived and globally mixed greenhouse gases. It has also been detected on other plane ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Four Corners Methane Hot Spot
The Four Corners Methane Hot Spot (also called the San Juan Basin methane leak or New Mexico methane source or various related permutations) refers to a clustering of large methane sources near San Juan Basin, near Four Corners, New Mexico, United States. It is perhaps the largest source of methane release in the United States and accounts for about a tenth of the annual gas industry amount. The area has upwards of 40,000 oil and gas wells. The exact cause of the leak remained unidentified as of 2015, but appeared to be related to coalbed methane extraction. The San Juan Basin contains the Fruitland coal formation. Ashley Ager, a geologist with LT Environmental, Inc., a company with oil and gas industry contracts, has argued that the leak is naturally occurring due to this formation contacting the surface. However, NASA The National Aeronautics and Space Administration (NASA ) is an independent agencies of the United States government, independent agency of the US fede ...

Natural Gas In The United States
Natural gas was the United States' largest source of energy production in 2016, representing 33 percent of all energy produced in the country. Natural gas has been the largest source of electrical generation in the United States since July 2015. In 2012, the United States produced 25.3 trillion cubic feet of marketed natural gas, with an average wellhead value of $2.66 per thousand cubic feet, for a total wellhead value of $67.3 billion. In 2013, the country produced 30.0 trillion cubic feet (TCF) of marketed gas. With 7,545 billion cubic feet (BCF), the leading gas-producing area in the United States in 2013 was Texas, followed by Pennsylvania (3,259 BCF), and Louisiana (2,407 BCF). US natural gas production achieved new record highs for each year from 2011 through 2015. Marketed natural gas production in 2015 was 28.8 trillion cubic feet, a 5.4 percent increase over 2014, and a 52 percent increase over the production of 18.9 trillion cubic feet in 2005.

Carbon Offset
A carbon offset is a reduction or removal of emissions of carbon dioxide or other greenhouse gases made in order to compensate for emissions made elsewhere. Offsets are measured in tonnes of carbon dioxide-equivalent (CO2e). One ton of carbon offset represents the reduction or removal of one ton of carbon dioxide or its equivalent in other greenhouse gases. One of the hidden dangers of climate change policy is unequal prices of carbon in the economy, which can cause economic collateral damage if production flows to regions or industries that have a lower price of carbon—unless carbon can be purchased from that area, which offsets effectively permit, equalizing the price. Within the voluntary market, demand for carbon offset credits is generated by individuals, companies, organizations, and sub-national governments who purchase carbon offsets to mitigate their greenhouse gas emissions to meet Carbon neutrality, carbon neutral, net-zero or other established Emission standard, e ...

Aspen Times
''The Aspen Times'' is an 11,500-circulation, 7-day-a-week newspaper in the ski resort town of Aspen, Colorado, United States, with a history dating back to 1881. History The Aspen Weekly Times' first issue was published April 23, 1881 when Aspen was a silver mining town, and the purpose of the newspaper was to bring news about the outside world to miners. The original owner was D.H. Waite & Co under the leadership of Davis Hanson Waite who sold the paper to B. Clark Wheeler in 1885 and later became Governor of Colorado. Within months, Wheeler converted the paper into a daily. Wheeler was a promoter and had various business interests. In 1880, Wheeler changed the name of the city from Ute City to Aspen. In the 1890s, the paper returned to a weekly publication schedule as the population of Aspen dropped due to the bust in silver prices. In 1956, Bil Dunaway, a U.S. Army 10th Mountain Division veteran, bought The Aspen Times, and over the next 35 years would amass a local media ...
