Show MoreEnergy Consumption
Continuing expansion of the world population results in increasing demands for energy to support human existence. I will concentrate on countries that use a lot of energy from fossil fuels, as well as examine countries that are increasingly becoming dependent on alternative forms of energy, such as nuclear energy and hydroelectricity, and others including geothermal and solar energy. The fossil fuels I am going to examine are coal, natural gas, and oil. Within the sector of oil, I will specifically show the demand for petroleum imports. I will also concentrate on renewable energies, such as nuclear energy, hydroelectricity, geothermal, and solar energy consumption. Some forms of energy are rapidly depleting, such…show more content…
Although natural gas is the cleanest fuel, it produces greenhouse gas emissions, lowers air quality and increases acid rain, and pollution from industries and transportation sectors. The United States imports the most natural gas, which amounts for 110,000 billion metric meters. Germany comes in second with about 80,000 billion cubic meters. 703,766 is the world total of natural gas imports (Key World Energy).
Oil is probably the most hazardous fossil fuel, with negative effects such as numerous oil spills, Co2 emissions, and other dangerous chemical emissions. This type of energy supplies the most widely used sector, being petroleum products. Most of this sector is primarily used for transportation. Not surprisingly, of all fossil fuels, the United States consumes the most crude oil, coming in at 526 Mt’s. The second highest consumer is Japan, with only 209 Mt’s. The world total is 2,057 Mt’s, and therefore, the United Sates consumes over 25% of the world total of oil consumed (Key World Energy). This excessive rate of consumption poses serious threats to the economic future of the United
States. If the country wants to keep unemployment down, inflation rates low, and the deficit to a minimum, then there needs to be more research and expansion in alternative fuel sources. This is becoming increasingly important due to uncertain relationships with the Middle
Energy conservation is a very important part of energy planning and its management. It not only saves energy resources for future, avoids wasteful utilisation of energy, provides solution to energy crisis and ensures higher per capita availability/ consumption but controls environmental degradation and pollution.
New strategy emphasies greater reliance on non-exhaustible and non-conventional sources of energy so as to conserve exhaustible conventional resources like coal, petroleum, natural gas etc. That is why efforts are being made to promote the development and use of non-conventional sources of energy. Another aspect of energy conservation is related to the reduction in consumption of energy.
This can be achieved by change in the individual habits, utilising latest technology, reduce the subsidy and increase the price of the energy. For example, a lot of electricity can be saved by using energy efficient lamps. The Superglue gives 20 per cent more light and saves up to 10 per cent energy.
Similarly many conventional boilers could be replaced by gasifies and a gas turbine stage could be added to the steam turbines to give a combined cycle operation producing 25 to 30 per cent more power from the same amount of coal. Increasing the plant load factor (PLF) of existing thermal plants is another area which offers good scope for energy planning. It is estimated that one per cent increase in PLF yields additional 4 billion units of electricity costing rupees 2,500 crores.
Another significant step in this direction would be to bring down the wastage of energy. In India about 23 per cent of electrical energy is lost during transmission and distribution. This can be curtailed by adopting appropriate measures. Penalty may be levied and legal actions initiated against power pilferage. Privatisation is another suggestion which can obtain desired results and improve the generation, transmission and distribution in the power sector. Energy is key to the modern development.
Hence, there is a need for serious thinking to improve this sector by inducting new technology, attracting more investment, developing non-conventional sources and inculcating habits for saving and conservation.
