Energy from renewable sources, such as the sun, wind and water, emit little or no carbon and could play a role in addressing climate change.

In an ideal world, energy would be limitless, affordable, and clean. Of course, the real world isn’t always ideal. Today, most of the world’s population gets its energy from carbon-based fuels like oil, natural gas and coal. These fuels are critical to meeting the growing demand for energy, yet they create emissions that have an impact on air quality and climate change.

Many big companies like BP, Exxon, Oil India, etc are working on alternate sources of enrgy but I do not think that any one is taking them really serious and understands the true potential of energy available for free. Just imagine every house has a wind mill producing sufficient energy for the home, or solar cells in each home.
