On a cold winter night we would have snuggled under a blanket to keep ourselfs comfortably warm. imagine if one would cover us with a dozen blankets it would get very hot !if we have experience this ,then we will understand global warming better.?

Global warming is the name given by scientists for the gradual increase in temperature that is from 15 Celsius to 22 Celsius of the Earth's surface that has worsened since the industrial revolution Over the past two decades the effect has become more marked. Considerable evidence exists that most of this warming has been caused by human activities... that's to say we have altered the chemical composition of the atmosphere through a buildup of greenhouse gases – primarily carbon dioxide, methane, and nitrous oxide. this is what the carbon footprints calls for


A carbon footprint is a measure of the impact our activities have on the environment, and in particular climate change. It relates to the amount of greenhouse gases produced in our day-to-day lives through burning fossil fuels for electricity, heating and transportation etc. 

The carbon footprint is a measurement of all greenhouse gases we individually produce and has units of tonnes (or kg) of carbon dioxide equivalent.

The pie chart above shows the main elements which
make up the total of an typical person's carbon footprint in the developed world.

A carbon footprint is made up of the sum of two parts, the primary footprint (shown by the green slices of the pie chart) and the secondary footprint (shown as the yellow slices).

1. The primary footprint is a measure of our direct emissions of CO2 from the burning of fossil fuels including domestic energy consumption and transportation (e.g. car and plane). We have direct control of these.

2. The secondary footprint is a measure of the indirect CO2 emissions from the whole lifecycle of products we use - those associated with their manufacture and eventual breakdown. To put it very simply – the more we buy the more emissions will be caused on our behalf.

In this day and age, the world needs to look at the different natural energy sources available to us. Global warming could be due our energy craving lifestyle, so we should look into more environmentally friendly energy sources LIKE SOLAR POWER.


Solar power is probably the cleanest, most viable form of renewable energy available and it can be used in several forms to help power your house. solar energy work by converting some of the energy in sunlight into a clean form of electricity that can be used in our houses .

Advantages of Solar Energy
There are many advantages of owning and operating a residential solar power system. • Solar panels have a long operational life. Most manufactures warrantee their solar panels for 20 years. • Producing electricity from solar panels is completely silent process • Once you have reached the pay off point, the amount of time it takes to pay for the residential solar power system's installation cost, from there on the system is earning you money. Money you did not have to spend buying electricity from the power company. • Once the solar power system is installed and configured it is pretty much a maintenance free electricity production system. If your system includes a battery pack you will need service the batteries periodically.

With all of these advantages why isn’t everyone using solar power for the home? There are some disadvantages to solar energy that you need to be aware of. These need to be taken into account as you consider installing a residential solar power system in your house. • A residential solar power system once installed becomes part of the house. When you move, the system stays with the house. • Solar power does not work well for large devices that use an electric heat element. Devices like electric hot water heater, electric whole house furnace, electric oven and range....
