Research says

• If each child saves one sheet of paper a day, then 40,000 trees are saved per year by students alone!
• If you take 1 hour break in office per day and switch off your monitor everytime you leave your desk, it would save 150 W-h (or 0.15 "units") of energy, which is enough to light a small lamp for 10 hours! So you can probably save electricity for five families
• Screen savers save computer screens, not energy. Start-ups and shutdowns do not use any extra energy, nor are they hard on your computer components. In fact, shutting computers down when you are finished using them actually reduces system wear - and saves energy
• Dirty tube lights and bulbs reflect less light and can absorb 50 percent of the light. So dust your tube lights and lamps regularly
• Save energy by reducing the amount of time refrigerator's door remains open
• Switching off your refrigerator when you go on holidays is a best way to save energy. To avoid smell, you can spread newspapers in it.
• Adopting light coloured walls and ceilings is an easy way to reduce energy consumption
• If you need to warm up or defrost small amounts of food, use a microwave instead of the stove to save energy. Microwave ovens use around 50 percent less energy than conventional ovens do. For large meals, however, the stove is usually more efficient.
• Drying clothes in sun instead of using auto-dryer of washing machine saves large amount of energy
• Using cotton napkins for every day use is better than the dispoable paper subtitutes
• The Gangotari glacier is retreating at a speed of about 30 metres every year. If warming continues, it will melt rapidly, releasing large volumes of water but once this source begins drying, there may be dry periods with very little water flowing in the river
• A 1-metre rise in sea level would displace about 7 million people in India
• And last but not the least, tell your friend to save energy and adopt the above measures
