We keep reading or hearing about air pollution and its deadly effect on our health and environment. More recently, we have also been hearing this new abbreviation being mentioned quite regularly: AQI – or Air Quality Index.
As the name suggests, AQI is nothing but a report on the quality of air that we are breathing in a particular place – it informs us and the authorities how polluted the air is, so that a decision can be taken on the measures to control the pollution level...
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.
