essay on energy conservation

When we save energy, we also save money. For it reduces the demand for fossil fuels like coal, oil and natural gas. Such fuels form non­renewable energy sources.

 

So the more we use them the less there is to go around. If we depend solely on them we will reach a point where we will go energy- bankrupt. This is why a lot of research is being done on alternative sources of energy which are also renewable. For instance, wind and solar power are renewable.

The sun and the winds are always part of our life. And they are abundantly available in many countries. Also, such energy is clean energy which does not emit carbon dioxide, the main culprit in global warming. Today there are many energy- efficient alternatives for all kinds of appliances. So we have the power to make better choices for reducing our consumption of energy.

There are many ways to conserve energy. Instead of using incandescent bulbs, we can use CFLs (compact fluorescent bulbs). They use only one-fourth the energy of the former and last 8-12 times longer. Instead of taking the car for every occasion, we can walk, take the bus or train, or join carpools. Every gallon saved reduces 22 pounds of carbon dioxide emissions.

We could also buy smaller, fuel-efficient cars instead of big gas guzzlers. We should try to avoid the use of plastic by buying reusable products instead of disposable ones. We should recycle as much as possible. For each pound of waste reduced or recycled, we can save energy and reduce C02 emissions by 1 pound. We must also try to reduce the garbage we generate daily.

We must plant trees which give shade. Green buildings which use natural light and energy- efficient materials save a lot of energy by reducing the need for more lights and air-conditioners, central heating, etc. On March 28, India observed Earth Hour day, when people all over India switched off lights for one hour from 8.30 pm to 9.30 pm. In other countries too, people did the same. It was part of a campaign for action on climate change. The concept of Earth Hour was born in Sydney, Australia, in 2007. Today it spans 65 countries.

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 degrada?tion 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-conven?tional sources of energy. Another aspect of energy conservation is related to the reduction in consump?tion 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 re?placed 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 an?other 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 pil?ferage. Privatisation is another suggestion which can obtain desired results and improve the genera?tion, transmission and distribution in the power sector. Energy is key to the modern development.

Hence, there is a need for serious thinking to im?prove this sector by inducting new technology, at?tracting more investment, developing non-conven?tional sources and inculcating habits for saving and conservation.

energy conversation is a very important of energy planning and its management is not only save energy resources for future, awards wasteful utilisation of energy, provide solution to energy crisis and their shoes highest per capita availability consumption birth control environmental degradation and pollution .

The electricity generated by the water is called hydro electricity
