Oil and gas as a source of energy in the U.S. have been plentiful. We had unlimited supplies and enjoyed it for a long time. In the past oil and gas have been fairly low in cost until OPEC increased prices.
Now America consumes great amounts of natural resources which means the feasibility of whether gas and oil will be around in the future as a source of energy. We may have to limit the use of gas and oil to making necessities only. At the present we are importing the majority of the gas that we use from other countries and holding on to ours.
Energy is vital to human existence and extracting of raw materials from the earth requires lots of energy and technology. Eventually there will be an energy shortage which means that we must develop new means of developing energy. For now we are safe but not for long. We must continue to explore and find new reservoirs to supply our growing consumption. There are alternatives that we can use to supply our energy needs.
