How can electricity/water/energy be saved? This appears to be a question so mundane

Thinking Outside the Box: Summer Energy Conservation

Read the following the information that I collected from the net

It’s time to say “hello” to summer and for those of you living in a hot climate like I do, you’re also saying a

reluctant “hello” to high summer electricity bills. Most of us already take the standard energy conservation steps,

such as setting our thermostat a degree or two higher and using ceiling fans to keep the air circulating, but there are

other ways to reduce energy use this summer. If you take a few minutes and challenge yourself to think outside the

box, you can brainstorm a bevy of unconventional energy conservation ideas. Here are a few I’ve come up with to

help you get started!

1. Head underground: If you have a basement, use it. It is cooler underground, which makes the basement the

perfect place for a playroom or a study place. You avoid the use of ac and fans thereby saving electricity

2. Air dry your hair: Skip the energy-hogging hair dryers and let your hair naturally dry. For those of us that live

in Delhi standing outside for about five minutes should do the trick! A two in one trick of saving electricity and

standing in the fresh air. 3. Walk down to burn the fat :If the distance to the market is not very far and is walking distance, you save even

more energy because you can leave the car/bike at home. 4. Exercise outdoors: Walking to your local market/coffee shop is one way to conserve energy this summer. If

you usually workout at home, whether it’s walking on the treadmill or exercising to your favorite DVD, head

outside a few times a week in the parks and gardens of Delhi! This gets you closer to the natural environment

invoking the divine spirit in you. With reference to our mission the fresh air is good for you and you’ll be

minimizing electricity use. 5. Ditch the oven: On the hottest days, avoid using the oven and use your solar cooker outside instead. Again

minmising exposure to electromagnetic radiation and saving electricity 6. Plug your outlets: Use child safety plugs in your unused outlets; this will prevent the hot outdoor air from

getting in. The benefit of this idea may be nominal but plugging the outlets certainly won’t hurt your energy

conservation efforts.Similarly avoid metal cupboards and almirahs(or place them in enclosed place) in your

bedrooms where you have airconditioners to ensure quicker cooling. A perfect energy saving effort.

7. Cover your terrace with 2,3 sacks in a pile and keep them wet with the water you wash clothes or the outlet of

your washing machine(needs planning to instal) and best have a garden water sprinkler (ideal) can maintain the

house at much lower temperatures and cool to the effect of an airconditioner. You need to convince your parents

for this innovative idea, it should have the cooling effect and does the work of 3 or 4 airconcitioners, provided

you are able to use recycled water(water that goes into the drain) 8. By changing the conventional bulbs at home to the LED bulbs the electricity and cost cutting of bulbs become

multifolded as these bulbs consume less than one fifth times the electricity as otherwise used by the conventional

ones

If these ideas have inspired you to think outside the box, I’d love to hear your unconventional tips to reduce energy

use this summer.

Not only hearing you can work on these ideas and implement these and get them when your back after school

vacations.

Make a project (working model) wherein you can improvise an existing machanism for saving energy or use your

creativity to initiate the process of using your basic scientific knowledge to put “science in action” for saving

energy.

Channelise your energy and brain power in this “OUT OF THE BOX THINKING IDEAS”

Your project in Physics/Chemistry could be a very simple practical and innovative idea. Incorporate the basic

concepts of Biology, Physics and Chemistry to complete this project.

This will be a stepping stone for - may be KVPY Exam or Intel project for CBSE Science fair competition

You can work in groups and the size of the group should not exceed 5

to create a lasting living garden.

How to go about making your miniature garden

1. Select a shallow medium sized dish of any shape.

2. Divide it into two halves using plastic sheet. Put soil on one side where plants are to be grown and sand on

the side to be used for landscaping. You can use marble pieces, pebbles etc for this purpose.
