China’s need for energy to serve its citizens and industries will accelerate tenfold in the period 2000-2035, i.e. from 1TWh to 9.6 TWh. Until now the share of renewables in China’s energy mix is about 17% while the major part of its energy, about 80%, is provided through fossil coal.

China’s challenges are related to its relatively very young renewable programs, and that the regions of highest energy demands are not matching China’s geographic distribution of its renewable energy production. Another challenge for China is the integration of its regional grids to a more efficient and optimized grid especially with consideration to the additional emerging renewable energies and the associated needs for storage. With these challenges a clear energy saving policy is needed for integrating renewable energy into China’s system. This is not an overnight and easy task especially if sustainable policies have to be taken in consideration for the reduction of greenhouse gas emissions which will remain to be one of the most serious difficulties for China not only from climatic view point but also from environmental and air quality prospective.
