New energy scale from small to large, standard from scratch, technology from follower to lead to run, run control ability from weak to strong, the development of new energy in China has reached a new level. After several years of practice and exploration we have a deeper understanding on the exploration, development of wind power and other new energy. State Grid Corporation Of China.

China's wind energy resources are mainly concentrated in the "Three North" region, accounting for more than 90% of the country; solar energy resources are concentrated in the western and northern regions, regions accounting for more than 80% of the country. Currently, more than 90% of the installed new energy capacity is concentrated in the region of the "Three North". China's wind energy resource maps State Grid Corporation Of China.

Mengxi, g , Eastern Inner Mongolia, g , Gansu,, northern Hebei four regional wind power installed capacity accounted for 50% of the country, but only 10% of the country's electricity consumption. Reverse distribution of new energy resources and load determines that China's new energy should large-scale centralized explored and long-distance delivery delivery. ■Wi d power generation ■Wind i ratio i for f the h country China's electric power distribution diagram 黑龙江 load 吉林 辽宁 内蒙古 新疆 青海 宁夏 甘肃 京 河北津 山西 山东 陕西 河南 西藏 湖北 四川 贵州 云南 浙江 湖南 江西 福建 广西 海南 广东 香港 澳门 ■ Electricity used accounts for the country 风电发电量占全国比例 用电量占全国比例 50% 51.3% 40% 江苏 安徽 上海 重庆 60% 30% 20% 10% 台 湾 18.1% 12.0% 33.3% 3% 0.7% 9.7% 2 0% 2.0% 11.6% 9.3% 3.4% 0% State Grid Corporation Of China.
