pollution free energy source

Now energy is produced from the following sources

• Coal -(Disadvantages: Pollution/Strip Mining)
• Natural Gas - (Disadvantages:Cost and Lack of Infrastructure)
• Hydro - (Disadvantages:Limited Availability/Environmental Concerns)
• Wind - (Disadvantages:Limited Site and Resource Availability)
• Solar Photovoltaic - (Disadvantages:Higher Cost)
• Nuclear – (Disadvantages:Waste disposal)

Among this power sources Solar PV (Photovoltaic) systems effectively deliver 10 Watts per square foot. Not one square inch of new land would be required to site PV. Theoretically, there are adequate residential, commercial, Government rooftops, and parking structures in California to power a substantial percentage of our State's electrical needs from solar.
At today's prices, a typical solar system costs approximately $6.00/watt, installed and has an operating life in excess of 25 years. For all intents and purposes, maintenance and operating costs are minimal.

What can you do about Global Warming ?

 Carbon dioxide is a colorless, odorless gas. It is produced both naturally and through human activities, such as burning gasoline, coal, oil, and wood.

Are you wandering that i start this topic with Carbon dioxide ?? Carbon dioxide is the main green house gas cause for global worming.So CO2 emission produced by your car is a cause of  the global warming.So what can you do ? Many thing you can do just decrease your petrol or gas consumption by car.Do not use the car if you in long ride.Another nice solve can be the use of pollution free Hybrid vehicle.

Effect of Carbon dioxide in global worming

Carbon dioxide is a colorless, odorless gas. It is produced both naturally and through human activities, such as burning gasoline, coal, oil, and wood.The carbon dioxide itself can cause headache, dizziness, nausea and other symptoms.CO2 plays an important role in the energy balance of our planet: It acts like a blanket over the planet by trapping long-wave radiation, which would otherwise radiate heat away from the planet . CO2 in the atmosphere will remain for a very long time, of the order of thousands of years.

To alleviate global warming, the emission of greenhouse gases like Carbon dioxide (72%),18% Methane and 9% Nitrous oxide (NOx) must be reduced.see effect of global worming in natural life.
It is seen that Carbon dioxide emissions therefore are the most important cause of global warming.The emissions of CO2 have been dramatically increased within the last 50 years and are still increasing by almost 3% each year.
