Switch that off!

We use electrical energy in our homes for lighting, cooking and even washing our clothes. A lot of this electrical energy comes from burning fossil fuels like coal and diesel. 

How does burning coal light a bulb?

The fuel (petroleum, coal or natural gas) is burnt to release heat. This, in turn, heats the water to produce steam that moves turbines to generate electricity.

It took millions and millions of years to create the fossil fuel that is available today. It will take millions of years to make more! Fossil fuels are therefore limited resources. If we continue to use them like we do today it will finally run out! To add to this, burning fossil fuels releases more greenhouses gases (carbon dioxide) into the Earth’s atmosphere, which leads to global warming. 

The best thing we can do is use less. We need to conserve!

Here are some simple things we can do at home ourselves to help reduce energy and pollution:

1.    Turn off the lights when you leave a room. In fact, make it a habit to go around the house to check – just in case mom has forgotten!

2.    Turn off all electrical devices when you are not using them. Yes, all of them, including your iPod!

3.    Encourage your family to buy energy saving electrical devices (bulbs, air conditioners, televisions etc.) – there are many options today. 

4.    Unplug devices rather than leaving them on standby. Devices like televisions, video game consoles, phone charges etc. continue to consume electricity even on stand by unless they are switched off from the power source.

5.    Research natural and renewable sources such as solar heaters and cookers. Suggest them to your family.

We don't grow into creativity!

It is not what we know that is important today, but what we do with it! It is our ability to analyze, think out of the box, ideate and create. We need creativity to get on with our lives.
