5. Solar energy
• In India 45% of households, mainly rural ones,
do not have access to electricity.
• India receives solar energy equivalent to more
than 5,000 Trillion kWh per year
• Geographical location
• Conventional Water Heaters Pollute-
Electric water heater needs about 6,400 kilowatt
hours of electricity per year which emits eight
tons of carbon dioxide (CO2) annually, which is
almost double that emitted by a typical modern
automobile Page 5

8. Light Bulb
• CFLs contain mercury. Is it dangerous?
• CFLs emit ultraviolet (UV) light
Light bulb of the new era
• General Electric has a new LED nine-watt
bulb that is energy-efficient, has a 22,500
hour life span (twice the amount as a CFL)

9. Benefits of LED bulb
• It will last at least 17 years
when used four hours a day.
• It's omnidirectional.
• It uses 10 percent less energy
than a 40 watt equivalent bulb.
• There's no mercury or other
toxic junk floating around inside.

10. Green Mobile Phones
• A mobile phone is made of hundreds of
different substances, some of which are
toxic, including PVC, phthalates, zinc,
lead, brominated flame retardants and
arsenic
• Nokia introduced a whole line of phones
and accessories free of PVC, and in 2008,
the company marketed the first phone with
no toxic flame retardants Page 10

12. Tips for Going Green
• Recycle bottles, cans, newspapers, cardboards, aluminum, glass,
electronics, plastics and packaging.
• Buy in bulk! Most local co-ops and health food stores carry bulk
items. You will be surprised at how much food you can buy in bulk.
Packaging is one of the main costs for food items, so not only is it
more earth-friendly to buy in bulk, but it saves the consumer money.
It also saves gas and time, especially if you have to bring items to
the recycling center.
• Don’t buy bottled water. Not only is bottled water expensive, but
plastic generates large amounts of waste. Get a good water filter to
purify your tap water.
• Go to your local library instead of buying books and movies. It saves
money, paper and ink.
• Invest in high-quality, long-lasting, earth-friendly products. You might
pay more now, but you'll be happy when you don't have to replace
items as frequently (and this means less waste). Page 12

13. • Many co-ops and health food stores carry bulk shampoos, conditioners,
lotions, oils and detergents. They are usually good quality and free of
chemicals. All you have to do is bring your own bottles.
• Make your own cleaning products. They are nontoxic, cut down on waste
and save your pocket book. All you need are a few simple ingredients like
baking soda, vinegar, lemon and soap.
• Buy only as much as you can use.
• If you eat meat, add one meatless meal a week. Meat is salty, and it's even
more expensive when you consider the related environmental costs of
mass-produced meat.
• Buy local and organic. It supports your community and saves on
transportation costs.
• Americans consume one third of the world’s annual paper production. It is
imperative that each of us do our part to consume as little paper as possible
in our daily lives. When working on the computer, edit as much as possible
before printing. Make double-sided copies and use the computer to e-mail
documents.
• Use wax paper whenever possible; it can be composted and plastic can’t.
Composting is a great way to reduce waste production and is beneficial for
the soil if you grow your own food.
• Use cloth whenever possible. Paper towels and napkins aren't good for the
environment. Page 13

14. • Use glass containers, cups and cookware.
• Paper or plastic at the grocery store? Neither! Bring your own bags.
Get into the habit of putting them back in your trunk when you are
finished putting groceries away.
• Don't buy disposable batteries, they are not eco-friendly. Buy a
charger and rechargeable batteries. They are much cheaper, and it
takes 50 times the energy contained within batteries to make them.
• Buy fruits and veggies loose from a local market rather than
packaged from supermarkets. This can be cheaper, saves
packaging, and the produce is more likely to be locally grown.
• Use energy efficient light bulbs; they can last eight times longer.
• Old clothes can be shredded and rewoven. If they're in good
condition, make sure you donate to charity shops in your
community.
• Keep your cell phones, computers and electronics as long as you
can. When you are done, recycle them responsibly, E-waste
contains mercury and other toxins, which are a growing
environmental problem. Page 14
