Hey guys...
Here is a very simple way of reducing power consumption and the best part is that anyone can do this without almost no effort at all!!
Its simple just change all wallpapers everywhere( cellphones, mp3 players, laptops) to use just a blank screen... Its simple yet effective, this way your battery lasts longer which means that you will have to recharge less and hence save power. Who needs these wallpapers! also it would be awesome to disable mp3 ringtones which consume loads of power...
Well its small steps like these which one day will make a big difference....
Cheers..
What is climate change ?
Imagine going for a picnic during your summer hols. You break into a sweat just thinking about it! And to think that your parents would have loved nothing better during their childhood days! Yes, the change in climate over the last few decades has been truly amazing.
Ever since the earth came into being there has been a climate system. The climate of a place is the average weather that it experiences over a period of time. The factors that determine the climate at a location are the rainfall, sunshine, wind, humidity, and temperature.
While changes in the weather may occur suddenly and noticeably, changes in the climate take a long time to settle in and are therefore less obvious. Throughout the earth's history there have been changes in the climate. There have been well-marked cold and hot periods and all life forms adapted naturally to this change.
The atmosphere surrounding the earth is made up of nitrogen (78%), oxygen (21%) and the remainder, 1%, is made up of trace gases (called so because they are present in very small quantities) that include the greenhouse gases carbon dioxide, methane, ozone, water vapour, and nitrous oxide. These greenhouse gases act as a blanket and protect it from the harmful ultra violet rays of the sun.

Here are some rather exaggerated versions of what sceptics believe might be our future...
As noted, an all white web page uses about 74 watts to display, while an all black page uses only 59 watts. I thought I would do a little math and see what could be saved by moving a high volume site to the black format.
Take at look at Google, who gets about 200 million queries a day. Let's assume each query is displayed for about 10 seconds; that means Google is running for about 550,000 hours every day on some desktop. Assuming that users run Google in full screen mode, the shift to a black background [on a CRT monitor! mjo] will save a total of 15 (74-59) watts. That turns into a global savings of 8.3 Megawatt-hours per day, or about 3000 Megawatt-hours a year. Now take into account that about 25 percent of the monitors in the world are CRTs, and at 10 cents a kilowatt-hour, that's $75,000, a goodly amount of energy and dollars for changing a few color codes.
Recycling is an excellent way of saving energy and conserving the environment. Did you know that:
- 1 recycled tin can would save enough energy to power a television for 3 hours.
- 1 recycled glass bottle would save enough energy to power a computer for 25 minutes.
- 1 recycled plastic bottle would save enough energy to power a 60-watt light bulb for 3 hours.
- 70% less energy is required to recycle paper compared with making it from raw materials.
Some Interesting Facts
- Up to 60% of the rubbish that ends up in the dustbin could be recycled.
- The unreleased energy contained in the average dustbin each year could power a television for 5,000 hours.

Some impacts from increasing temperatures are already happening.
* Ice is melting worldwide, especially at the Earth’s poles. This includes mountain glaciers, ice sheets covering West Antarctica and Greenland, and Arctic sea ice.
* Researcher Bill Fraser has tracked the decline of the Adélie penguins on Antarctica, where their numbers have fallen from 32,000 breeding pairs to 11,000 in 30 years.
* Sea level rise became faster over the last century.
* Some butterflies, foxes, and alpine plants have moved farther north or to higher, cooler areas.
* Precipitation (rain and snowfall) has increased across the globe, on average.
* Spruce bark beetles have boomed in Alaska thanks to 20 years of warm summers. The insects have chewed up 4 million acres of spruce trees.
Other effects could happen later this century, if warming continues.
* Sea levels are expected to rise between 7 and 23 inches (18 and 59 centimeters) by the end of the century, and continued melting at the poles could add between 4 and 8 inches (10 to 20 centimeters).
* Hurricanes and other storms are likely to become stronger.
* Species that depend on one another may become out of sync. For example, plants could bloom earlier than their pollinating insects become active.
* Floods and droughts will become more common. Rainfall in Ethiopia, where droughts are already common, could decline by 10 percent over the next 50 years.
* Less fresh water will be available. If the Quelccaya ice cap in Peru continues to melt at its current rate, it will be gone by 2100, leaving thousands of people who rely on it for drinking water and electricity without a source of either.
* Some diseases will spread, such as malaria carried by mosquitoes.
* Ecosystems will change—some species will move farther north or become more successful; others won’t be able to move and could become extinct. Wildlife research scientist Martyn Obbard has found that since the mid-1980s, with less ice on which to live and fish for food, polar bears have gotten considerably skinnier. Polar bear biologist Ian Stirling has found a similar pattern in Hudson Bay. He fears that if sea ice disappears, the polar bears will as well.
| Pollutant | Sources | Effects |
|---|---|---|
| Ozone A colorless gas that is the major constituent of photochemical smog at the Earth's surface. In the upper atmosphere (stratosphere), however, ozone is beneficial, protecting us from the sun's harmful rays. | Ozone is formed in the lower atmosphere as a result of chemical reactions between oxygen, volatile organic compounds, and nitrogen oxides in the presence of sunlight, especially during hot weather. Sources of such harmful pollutants include vehicles, factories, landfills, industrial solvents, and numerous small sources such as gas stations, and farm and lawn equipment. | Ozone causes significant health and environmental problems at the Earth's surface. It can irritate the respiratory tract, produce impaired lung function and cause throat irritation, chest pain, cough, and lung inflammation. It can also reduce the yield of agricultural crops and injure forests and other vegetation. Ozone is the most injurious pollutant to plant life. |
| Carbon Monoxide Odorless and colorless gas emitted in the exhaust of motor vehicles and other kinds of engines where there is incomplete fossilfuel combustion. | Automobiles, buses, trucks, small engines, and some industrial processes. High concentrations can be found in confined spaces like parking garages, poorly ventilated tunnels, or along roadsides during periods of heavy traffic. | Reduces the ability of blood to deliver oxygen to vital tissues, affecting primarily the cardiovascular and nervous systems. Lower concentrations have been shown to adversely affect individuals with heart disease; higher concentrations can cause dizziness, headaches, and fatigue. |
| Nitrogen Dioxide Light brown gas at lower concentrations; in higher concentrations becomes an important component of unpleasant-looking brown, urban haze. | Result of burning fuels in utilities, industrial boilers, cars, and trucks. | One of the major pollutants that causes smog and acid rain. Can harm humans and vegetation when concentrations are sufficiently high. |
| Particulate Matter Solid matter or liquid droplets from smoke, dust, fly ash and condensing vapors that can be suspended in the air for long periods of time. | Industrial processes, smelters, automobiles, burning industrial fuels, woodsmoke, dust from paved and unpaved roads, construction, and agricultural ground breaking. | These microscopic particles can affect breathing and respiratory health, causing increased respiratory disease and lung damage, and possibly premature death. |
| Sulfur Dioxide Colorless gas, odorless at low concentrations but pungent at very high concentrations. | Emitted largely from industrial, institutional, utility and apartment-house furnaces and boilers, as well as petroleum refineries, smelters, paper mills, and chemical plants. | One of the major pollutants that cause smog. Can also, at high concentrations, affect human health, especially among asthmatics, and acidify lakes and streams. |
| Lead Lead and lead compounds can adversely affect human health through either ingestion of lead-contaminated soil, dust, paint, or direct inhalation. | Transportation sources using lead in their fuels, coal combustion, smelters, car battery plants, and combustion of garbage containing lead products. | Elevated lead levels can adversely affect mental development, kidney function, and blood chemistry. Young children are particularly at risk. |
| Toxic Air Pollutants Includes pollutants such as arsenic, asbestos, and benzenes. | Chemical plants, industrial processes, motor vehicle emissions and fuels, and building materials. | Known or suspected to cause cancer, respiratory effects, birth defects, and reproductive and other serious health effects. |
| Stratospheric Ozone Depleters Chemicals such as chlorofluorocarbons (CFCs), halons, carbon tetrachloride, and methyl chloroform. These chemicals rise to the upper atmosphere where they destroy the protective ozone layer. | Industrial household refrigeration, cooling and cleaning processes, car and home air conditioners, some fire extinguishers, and plastic foam products. | Increased exposure to UV radiation could potentially cause an increase in skin cancer, cataracts, suppression of the human immune response system, and environmental damage. |
| Greenhouse gases Gases that build up in the atmosphere that may induce global climate change or the “greenhouse effect.”They include carbon dioxide, methane, and nitrous oxide. | The main man-made source of carbon dioxide emissions is fossil fuel combustion for energy-use and transportation. Methane comes from landfills, cud-chewing livestock, coal mines, and rice paddies. Nitrous oxide results from industrial processes, such as nylon fabrication. | The extent of the effects of climate change on human health and the environment is still uncertain, but could include increased global temperature, increased severity and frequency of storms and other “weather extremes,” melting of the polar ice cap, and sea-level rise. |
Here are 50 things that everyone can do to stop global warming and its effects. Most of them are simple things that hardly require any effort on your part. So please try them out and pass it on.
1.
Replace a regular incandescent light bulb with a compact fluorescent light bulb (cfl)
CFLs use 60% less energy than a regular bulb. This simple switch will save about 300 pounds of carbon dioxide a year.
2.
Install a programmable thermostat
Programmable thermostats will automatically lower the heat or air conditioning at night and raise them again in the morning. They can save you $100 a year on your energy bill.
3.
Move your thermostat down 2° in winter and up 2° in summer
Almost half of the energy we use in our homes goes to heating and cooling. You could save about 2,000 pounds of carbon dioxide a year with this simple adjustment.
4.
Clean or replace filters on your furnace and air conditioner
Cleaning a dirty air filter can save 350 pounds of carbon dioxide a year.
5.
Choose energy efficient appliances when making new purchases
Look for the Energy Star label on new appliances to choose the most energy efficient products available.
6.
Do not leave appliances on standby
Use the "on/off" function on the machine itself. A TV set that's switched on for 3 hours a day (the average time Europeans spend watching TV) and in standby mode during the remaining 21 hours uses about 40% of its energy in standby mode.
7.
Wrap your water heater in an insulation blanket
You’ll save 1,000 pounds of carbon dioxide a year with this simple action. You can save another 550 pounds per year by setting the thermostat no higher than 50°C.
8.
Move your fridge and freezer
Placing them next to the cooker or boiler consumes much more energy than if they were standing on their own. For example, if you put them in a hot cellar room where the room temperature is 30-35ºC, energy use is almost double and causes an extra 160kg of CO2 emissions for fridges per year and 320kg for freezers.
9.
Defrost old fridges and freezers regularly
Even better is to replace them with newer models, which all have automatic defrost cycles and are generally up to two times more energy-efficient than their predecessors.
10.
Don't let heat escape from your house over a long period
When airing your house, open the windows for only a few minutes. If you leave a small opening all day long, the energy needed to keep it warm inside during six cold months (10ºC or less outside temperature) would result in almost 1 ton of CO2 emissions.
11.
Replace your old single-glazed windows with double-glazing
This requires a bit of upfront investment, but will halve the energy lost through windows and pay off in the long term. If you go for the best the market has to offer (wooden-framed double-glazed units with low-emission glass and filled with argon gas), you can even save more than 70% of the energy lost.
12.
Get a home energy audit
Many utilities offer free home energy audits to find where your home is poorly insulated or energy inefficient. You can save up to 30% off your energy bill and 1,000 pounds of carbon dioxide a year. Energy Star can help you find an energy specialist.
13.
Cover your pots while cooking
Doing so can save a lot of the energy needed for preparing the dish. Even better are pressure cookers and steamers: they can save around 70%!
14.
Use the washing machine or dishwasher only when they are full
If you need to use it when it is half full, then use the half-load or economy setting. There is also no need to set the temperatures high. Nowadays detergents are so efficient that they get your clothes and dishes clean at low temperatures.
15.
Take a shower instead of a bath
A shower takes up to four times less energy than a bath. To maximise the energy saving, avoid power showers and use low-flow showerheads, which are cheap and provide the same comfort.
16.
Use less hot water
It takes a lot of energy to heat water. You can use less hot water by installing a low flow showerhead (350 pounds of carbon dioxide saved per year) and washing your clothes in cold or warm water (500 pounds saved per year) instead of hot.
17.
Use a clothesline instead of a dryer whenever possible
You can save 700 pounds of carbon dioxide when you air dry your clothes for 6 months out of the year.
18.
Insulate and weatherize your home
Properly insulating your walls and ceilings can save 25% of your home heating bill and 2,000 pounds of carbon dioxide a year. Caulking and weather-stripping can save another 1,700 pounds per year. Energy Efficient has more information on how to better insulate your home.
19.
Be sure you’re recycling at home
You can save 2,400 pounds of carbon dioxide a year by recycling half of the waste your household generates.
20.
Recycle your organic waste
Around 3% of the greenhouse gas emissions through the methane is released by decomposing bio-degradable waste. By recycling organic waste or composting it if you have a garden, you can help eliminate this problem! Just make sure that you compost it properly, so it decomposes with sufficient oxygen, otherwise your compost will cause methane emissions and smell foul.
21.
Buy intelligently
One bottle of 1.5l requires less energy and produces less waste than three bottles of 0.5l. As well, buy recycled paper products: it takes less 70 to 90% less energy to make recycled paper and it prevents the loss of forests worldwide.
22.
Choose products that come with little packaging and buy refills when you can
You will also cut down on waste production and energy use... another help against global warming.
23.
Reuse your shopping bag
When shopping, it saves energy and waste to use a reusable bag instead of accepting a disposable one in each shop. Waste not only discharges CO2 and methane into the atmosphere, it can also pollute the air, groundwater and soil.
24.
Reduce waste
Most products we buy cause greenhouse gas emissions in one or another way, e.g. during production and distribution. By taking your lunch in a reusable lunch box instead of a disposable
one, you save the energy needed to produce new lunch boxes.
25.
Plant a tree
A single tree will absorb one ton of carbon dioxide over its lifetime. Shade provided by trees can also reduce your air conditioning bill by 10 to 15%. The Arbor Day Foundation has information on planting and provides trees you can plant with membership.
26.
Switch to green power
In many areas, you can switch to energy generated by clean, renewable sources such as wind and solar. In some of these, you can even get refunds by government if you choose to switch to a clean energy producer, and you can also earn money by selling the energy you produce and don't use for yourself.
27.
Buy locally grown and produced foods
The average meal in the United States travels 1,200 miles from the farm to your plate. Buying locally will save fuel and keep money in your community.
28.
Buy fresh foods instead of frozen
Frozen food uses 10 times more energy to produce.
29.
Seek out and support local farmers markets
They reduce the amount of energy required to grow and transport the food to you by one fifth. Seek farmer’s markets in your area, and go for them.
30.
Buy organic foods as much as possible
Organic soils capture and store carbon dioxide at much higher levels than soils from conventional farms. If we grew all of our corn and soybeans organically, we’d remove 580 billion pounds of carbon dioxide from the atmosphere!
31.
Eat less meat
Methane is the second most significant greenhouse gas and cows are one of the greatest methane emitters. Their grassy diet and multiple stomachs cause them to produce methane, which they exhale with every breath.
32.
Reduce the number of miles you drive by walking, biking, carpooling or taking mass transit wherever possible
Avoiding just 10 miles of driving every week would eliminate about 500 pounds of carbon dioxide emissions a year! Look for transit options in your area.
33.
Start a carpool with your coworkers or classmates
Sharing a ride with someone just 2 days a week will reduce your carbon dioxide emissions by 1,590 pounds a year. eRideShare.com runs a free service connecting north american commuters and travelers.
34.
Don't leave an empty roof rack on your car
This can increase fuel consumption and CO2 emissions by up to 10% due to wind resistance and the extra weight - removing it is a better idea.
35.
Keep your car tuned up
Regular maintenance helps improve fuel efficiency and reduces emissions. When just 1% of car owners properly maintain their cars, nearly a billion pounds of carbon dioxide are kept out of the atmosphere.
36.
Drive carefully and do not waste fuel
You can reduce CO2 emissions by readjusting your driving style. Choose proper gears, do not abuse the gas pedal, use the engine brake instead of the pedal brake when possible and turn off your engine when your vehicle is motionless for more than one minute. By readjusting your driving style you can save money on both fuel and car mantainance.
37.
Check your tires weekly to make sure they’re properly inflated
Proper tire inflation can improve gas mileage by more than 3%. Since every gallon of gasoline saved keeps 20 pounds of carbon dioxide out of the atmosphere, every increase in fuel efficiency makes a difference!
38.
When it is time for a new car, choose a more fuel efficient vehicle
You can save 3,000 pounds of carbon dioxide every year if your new car gets only 3 miles per gallon more than your current one. You can get up to 60 miles per gallon with a hybrid! You can find information on fuel efficiency on FuelEconomy and on GreenCars websites.
39.
Try car sharing
Need a car but don’t want to buy one? Community car sharing organizations provide access to a car and your membership fee covers gas, maintenance and insurance. Many companies – such as Flexcar - offer low emission or hybrid cars too! Also, see ZipCar.
40.
Try telecommuting from home
Telecommuting can help you drastically reduce the number of miles you drive every week. For more information, check out the Telework Coalition.
41.
Fly less
Air travel produces large amounts of emissions so reducing how much you fly by even one or two trips a year can reduce your emissions significantly. You can also offset your air travel carbon emissions by investingin renewable energy projects.
42.
Encourage your school or business to reduce emissions
You can extend your positive influence on global warming well beyond your home by actively encouraging other to take action.
43.
Join the virtual march
The Stop Global Warming Virtual March is a non-political effort to bring people concerned about global warming together in one place. Add your voice to the hundreds of thousands of other people urging action on this issue.
44.
Encourage the switch to renewable energy
Successfully combating global warming requires a national transition to renewable energy sources such as solar, wind and biomass. These technologies are ready to be deployed more widely but there are regulatory barriers impeding them. U.S. citizens, take action to break down those barriers with Vote Solar.
45.
Protect and conserve forest worldwide
Forests play a critial role in global warming: they store carbon. When forests are burned or cut down, their stored carbon is release into the atmosphere - deforestation now accounts for about 20% of carbon dioxide emissions each year. Conservation International has more information on saving forests from global warming.
46.
Consider the impact of your investments
If you invest your money, you should consider the impact that your investments and savings will have on global warming. Check out SocialInvest and Ceres to can learn more about how to ensure your money is being invested in companies, products and projects that address issues related to climate change.
47.
Make your city cool
Cities and states around the country have taken action to stop global warming by passing innovative transportation and energy saving legislation. If you're in the U.S., join the cool cities list.
48.
Tell Congress to act
The McCain Lieberman Climate Stewardship and Innovation Act would set a firm limit on carbon dioxide emissions and then use free market incentives to lower costs, promote efficiency and spur innovation. Tell your representative to support it.
49.
Make sure your voice is heard!
People must have a stronger commitment from their government in order to stop global warming and implement solutions and such a commitment won’t come without a dramatic increase in citizen lobbying for new laws with teeth.

Greetings fellow earthlings....
First Off , a few facts about our Home.
Earth is the third planet from the Sun and is the largest of the terrestrial planets in the Solar System in diameter, mass and density. It is also referred to as the Earth, Planet Earth, the World, and Terra.
Home to millions of species,including humans, Earth is the only place in the universe where life is known to exist. Scientific evidence indicates that the planet formed 4.54 billion years ago, and life appeared on its surface within a billion years. Since then, Earth's biosphere has significantly altered the atmosphere and other abiotic conditions on the planet, enabling the proliferation of aerobic organisms as well as the formation of the ozone layer which, together with Earth's magnetic field, blocks harmful radiation, permitting life on land.
Earth's outer surface is divided into several rigid segments, or tectonic plates, that gradually migrate across the surface over periods of many millions of years. About 71% of the surface is covered with salt-water oceans, the remainder consisting of continents and islands; liquid water, necessary for all known life, is not known to exist on any other planet's surface. Earth's interior remains active, with a thick layer of relatively solid mantle, a liquid outer core that generates a magnetic field, and a solid iron inner core.
