Emissions & Generation Resource Integrated Database mix, and heat input. eGRID data also include plant identification, location, and structural information. The emissions information in eGRID include carbon dioxide (CO), nitrogen oxides (NO), sulfur dioxide (SO), methane (CH), nitrous oxide (NO),and carbon dioxide equivalent (COe). CO, CH, and NO are greenhouse gases (GHG) that contribute to global warming or climate change. NO and SO contribute to unhealthy air quality and acid rain in many parts of the country. eGRID's resource mix information includes the following fossil fuel resources: coal, oil, gas, other fossil; nuclear resources; and the following renewable resources: hydroelectric (water), biomass (including biogas, landfill gas
Nitrous oxide and inhibit pain signalling. Exactly how causes the release of endogenous opioid peptides remains uncertain. Nitrous oxide is a colourless, non-toxic gas with a faint, sweet odour. Nitrous oxide supports combustion by releasing the dipolar bonded oxygen radical, thus it can relight a glowing splint. The above reaction is the route adopted by the commercial chemical industry to produce azide salts, which are used as detonators. The gas was first synthesised in 1772 by English natural philosopher and chemist Joseph Priestley, who called it "phlogisticated nitrous air" (see phlogiston) or "inflammable nitrous air". Priestley published his discovery in the book
