Mankind depends on energy to survive! Without energy it would be impossible to maintain our lifestyle.

For many years mankind has generated energy by burning fossil fuels. Until today 80 % of the World energy comes from fossil fuels. In China over 92 % is based on fossil fuels. As fossil fuels are not renewable and one day will come to an end, so...

Renewable energy sources!!!

Oxford Dictionary

Noun (usually renewables) A source of energy that is not depleted by use, such as;
 Biomass  Biofuels  Geothermal  Water  Wind

 Solar

What about the environment?

Fossil fuel processing and energy generation accounts for 14 billion tonnes of CO2 per year!

Biomass and biofuels are burnt to generate energy, producing CO2!

Not only renewable, it must be clean!

Renewables which generate energy without generating CO2.

Market outlook

Solar and wind power grew the most within the clean renewable sources, both have achieved and surpassed early forecasts.

In the past ten years:  Solar energy has grown over 35 times.  Wind power grew over 10 times and by the end of 2010 reached the expected for 2012.
