Question

essay on save energy ?

Answer 1

Saving energy is a very important thought which we must put in practice immediately and regularly.

We are dependent on the ecosystem on Earth. We have limited natural resources including water, minerals etc. We have a lot of Solar energy that is available to us. But we have not been able to convert it to other forms cheaply yet.

We are depleting oil, gas and other sources much faster than they can form again in the Earth's crust. We need to conserve energy and use of fuels in order that in future our descendants can still use them. We should depend more on renewable resources.  Saving energy also reduces pollution.

Save Earth movement works for the awareness of Energy saving. On the Earth day, all lights are switched off to remind ourselves of the importance of energy savings.  Reduction of use of energy also reduces pollution.

How to save energy:

We must switch off lights, TV, motors etc., when they are not in use. We can switch off computers when not in use.   Use gas stove carefully to save cooking gas. Use cell phones judiciously so the batteries last longer.

Many Europeans have downtowns (village centers) where people cannot take motor vehicles. They can only walk through the streets. We can also implement the same rules. We must walk nearby distances instead of using motor vehicles.

We must switch off engines at the red traffic lights while waiting.  Sharing transport or using public transport reduces fuel usage. reduces pollution too.

Recycling technologies and methods must be more encouraged and implemented in India to reduce wastage and to save energy too.  More efficient fuels can reduce energy usage.

Answer 2

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.
