Sunlight, readily available for 250 to 300 days in most parts of India, can help schools operate better.

India has set a target of 227 GW of installed capacity from renewable energy by 2022. Of this, nearly 144 GW would be sourced from solar energy, while 67 GW would come from wind energy. Although wind, solar, biogas and water are all renewable energy sources for power, solar energy is considered to be the most affordable alternative to polluting fossil-fuel based power-plants. Easy installation and electricity generation also make solar energy the best bet among renewables...

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.

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.
