The demand curves for competitive firms, however, are almost perfectly elastic because no matter how these firms change their production, in a perfectly competitive economy, there are so many firms out there that its production will not affect anything.onopolistic competition, because there are so many relatively weak firms, there are no barriers to entry. Companies can enter the market relatively easily (although, of course, not as perfectly easy as in perfect competition). This makes for a long-term equilibrium competition of no profit.
How Is Natural Gas Produced. Natural gas is found in oil fields, natural-gas fields and coal beds. Since natural gas isn't a pure product, it needs to undergo processing before it can be used as consumer fuel. The gas is extracted from a field using a decompression process called retrograde condensation.
Natural gas is a versatile, clean-burning, and efficient fuel that is used in a wide variety of applications. In the 19th and early 20th centuries, natural gas was used primarily for street and building lighting, providing what was known as gaslight.Today, improved distribution of gas has made possible a wide variety of uses in homes, businesses, factories, and power plants.he fastest growing use of natural gas today is for the generation of electric power. Natural gas power plants usually generate electricity in gas turbines (which are derived from jet engines), directly using the hot exhaust gases of fuel combustion.
