Renewable energy is a source of energy that can never be exhausted. We can obtain renewable energy from the sun (solar energy), from the water (hydropower), from the wind (windmills), from hot dry rocks, magma, hot water springs (geothermal) and even from firewood, animal manure, crop residues and waste (Biomass).

Solar Energy Facts
Something that keeps a lot of people from deciding to take the plunge into solar energy is the mistaken idea that solar energy is in some manner a lower quality energy than electricity produced from fossil fuels. In actuality, solar energy's emissions free conversion to electricity makes it an even more beneficial energy source as far as the environment is concerned.
Do you know which country utilizes solar energy to the highest degree? Despite its Northern location far from the equator and its comparatively small population, Germany presently employs more solar energy than any other country. This should dispel any of the misconceptions about solar energy not being a credible energy solution in northern climates.
GLOBAL WARMING AWARENESS
Global Warming Facts - 8 Facts about Global Warming
Causes of Global Warming - The Green house gases are the main culprits of the global warming. The green house gases like carbon dioxide, methane, and nitrous oxide are playing hazards in the present times.
Green House Gasses are the ingredients of the atmosphere that add to the greenhouse effect.
Al Gore Global Warming Initiative - Gore has written a book that archives his advice that Earth is dashing toward an immensely warmer future.
Global warming is caused by green house gases, which trap in the sun’s infrared rays in the earth’s atmosphere, which in turn heat up the earth’s atmosphere. These green house effect warming is called as global warming. The effects of green house effect are visible more prominently in the recent years, with number of natural calamities on the rise in the whole world.
The global warming has happened in the past few years and is evident from the rise in mean temperature of the earth’s atmosphere. The main causes for the global warming are attributed to release of green house gases by human activities. The main gases contributing to green house effect are carbon dioxide, water vapor, methane and nitrous oxide. The largest producers of these gases are the thermal power plants, which burn the fossil fuels and produce these gases in large quantities. The second biggest sources of these green house gases are the road vehicles and industries.
The global warming has led to increase in mean earth surface temperature and thus melting of polar ice. There are frequent melt down of glaciers that result in floods and other natural calamities. The melting of ice at the poles had led the mean sea level. And further increase in temperature may further melt the ice and lead to further increase in mean sea level, which will engulf low lying countries.
The effect of global warming is very evident on the animal kingdom also. Some animals have become extinct due to loss of their natural habitat or their inability to evolve to the rapid changes in the climate. Also there is a change in their life style because of the changes in the seasons. The migrating birds have changed their time of travel and also their place of migration.
