Renewable energy can be a viable power source for our airports, stadiums & homes. Piu entered the house panting one summer afternoon and said, “I have no energy to do anything.” She had come back from school and was completely exhausted. Her mother came to her rescue and handed her a glass saying, “This should energise you.
How does light get converted into electricity and what are the components that constitute a solar panel module? Let's find out.
Just step into your house and look around. All our appliances from our refrigerator to air-conditioner to smartphones, everything would become useless in a world without electricity. This is why electricity is considered one the most valuable commodities in the world.
D Suresh lives in Kilpauk in Chennai in his green and sustainable home.

The movement towards a cleaner environment got a huge push recently when the Irish Parliament passed a bill that would make Ireland world's first country to fully divest public money from fossil fuels.
Wind is a form of kinetic energy, i.e. energy in motion. For centuries, people have used windmills to convert moving energy into mechanical forms to perform tasks such as grinding grain and pumping water. Let's learn how to make a pinwheel. We will see how a basic turbine works and how wind can create mechanical force.
Oh, no . . . The climb to the third floor was killing me! The lift was not working. Our security uncle said there had been a power cut. My legs hurt. We had had our inter-house football matches at school today. I was tired and famished. After much huffing and puffing, I reached home. My dad opened the door. “Pa, the lift is not working. I had to climb up the stairs!” I said, as I dropped my heavy bag with a "thud" on the floor. “
“Pom! Stop now, hfff . . . hfff . . . I can’t run anymore,” shouted Piu.

It was getting dark. Soon there was a big moon over the sky.
“Piu we have to go home,” said Pom...
There are some schools that have taken up energysaving initiatives to become energy-efficient.
Electric bulbs, cars, fans, air conditioners, televisions, cooking ovens, chulhas, machines... the word ‘energy’ conjures up images of almost everything that makes up our everyday lives. Some forms of energy are renewable, including energy harnessed from the sun, wind and water. Energy produced from garbage, such as dead trees, branches, leftover crops and gobar, or dung, along with other forms of livestock manure—resources collectively called ‘biomass’—can also be used and then replenished.
There is also a second category, non-renewable energy. All forms of fossil fuel—oil, coal and natural gas—are examples. These fuels were made over 300 million years ago and we are slowly and surely depleting the reserves.
Are appliances in India energy efficient? Does the government promote the best technologies? Do companies sell their most energy efficient products? This short whiteboard animation tries to answer these questions.
