The main aim for preventing global warming is to decrease the use of the non renewable source of energy and to increase the use of renewable source. This resource includes the use of:
Sunlight,
Wind power,
Tidal energy
Geothermal energy,
Hydro energy
Hydrogen
Nuclear power not exactly a renewable source.
The burning of fossil fuels releases large amounts of carbon dioxide. The leading cause of global warming, but renewable energy does not have that effect.
The most effective of all these renewable source of energy is the sunlight. The most efficient of all this is hydrogen fuel. A lot of research is going on the development of these non efficient renewable sources of energy but till date very little achievement has been found.
Cars and trucks apart from industries are another significant source approx 25 percent of U.S. carbon dioxide emissions. It is very important to address global warming due to the sources like emissions from cars and trucks.
Making policies among the top developed and the developing countries of the world to make a protocols to check the pollution. Like the Protocol' that industrialized countries — called 'Annex I' countries — should reduce emissions of greenhouse gases to at least five per cent below their average 1990 levels by 2012.
