Natural gas in the United States natural gas and natural gas liquids. The exploration for and production of natural gas and petroleum form a single industry, and many wells produce both oil and gas. Because of the greater supply, consumer prices for natural gas are significantly lower in the United States than in Europe and Japan. The low price of natural gas, together with its smaller carbon footprint compared to coal, has encouraged a rapid growth in electricity generated from natural gas. Between 2005 and 2014, US production of natural gas liquids (NGLs) increased 70%, from 1.74 million barrels per day in 2005 to 2.96 million
Carbon dioxide whiteflies and spider mites in a greenhouse. It has been proposed that from power generation be bubbled into ponds to stimulate growth of algae that could then be converted into biodiesel fuel. In medicine, up to 5% carbon dioxide (130 times atmospheric concentration) is added to oxygen for stimulation of breathing after apnea and to stabilize the balance in blood. Carbon dioxide can be mixed with up to 50% oxygen, forming an inhalable gas; this is known as Carbogen and has a variety of medical and research uses. Carbon dioxide is used in enhanced oil recovery where it is injected
