Renewable energy is very important for human development, which has become a consensus. The development of renewable energy has already experienced a period of exploration, exploration, design, development, investment and output. It is very important to evaluate the global renewable energy resources.

The evaluation method mainly includes observation data and numerical simulation, and the numerical simulation method can obtain the spatial and temporal continuous wind and solar energy distribution data, and is the most effective method of resource evaluation. This method mainly through data collection and collation, through the collection of terrain data, SST data, reanalysis data, observation data, the data assimilation into the WRF mesoscale numerical model, and simulation calculation, the simulation results were statistically analyzed, the wind energy, solar energy resource distribution map, so you can clearly describe what resources are distributed in which.

Through the observation of our team, we found that the wind resources in the north of China and the east of the East are very rich, but most of the regional wind resources in Central Asia are also relatively good.

According to estimates, the global wind energy resources amount to 1640 terawatts, better developed 73 tw. According to the abundant degree of wind energy resources and the global climate zones, the global wind energy resources are mainly distributed in the 4 latitudes:

One is the high latitude North wind. Mainly includes the Arctic region and some Russian, Canada and America, is located at 60 degrees north latitude. The wind energy is the most abundant area is located in Greenland and east of the ocean, the annual average wind speed reached 12 meters / seconds, the wind power density reached 1000 watt / square meters.
