Conventional energy reserves in the world and some can only be maintained for half a century (such as oil can only be mined for 41 years). Gas can only mining 67 years, most only 192 years of mining coal.The world consumes 84 million barrels of oil a day, today the world's population has exceeded 6 billion more than the 19th century more than 2-fold increase in final energy consumption according to statistics has increased more than 16-fold.

Facts have proved that we must be the world's carbon dioxide emissions in 2050 reduced by half. As the carbon emissions of the main cause of the energy demand will double. Renewable energy must be used, but this is not enough to change today's energy portfolio we look at the world of 2030:

1,80 million people, of which 60% will be living in cities

2,20 million people will become middle class

3, the demand for electricity than the 2007 high of 76%

4, only China and India, the two countries will be incremental energy demand accounts for more than 50%

Concept of sustainable development:

Showed a growth in demand for energy in all aspects of the global community, the most acute problem is issued every three units of the power plant's energy, only one unit is the effective use of the client. Therefore, for the work carried out by the waste of that take full advantage of the unused power of work, the most likely to bring the best return for the business and residential.
