What kind of energy is the long-term main energy in the world energy consumption structure, and its proportion is gradually increasing.

China's energy structure is dominated by coal, which has always accounted for about 70% of primary energy consumption. China imports 55% of its oil consumption, and its energy security is facing increasingly severe challenges.

China's coal reserves are 10345 million tons, and the remaining proven recoverable reserves account for about 13% of the world, ranking third in the world. The proven reserves of petroleum and natural gas resources are relatively insufficient, and unconventional fossil energy reserves such as oil shale and coalbed methane have great potential.

The misty pine and cypress fluttering in the wind, like a white-haired witch, flutters in the wind, watching the snow in the western sky, praying for good weather in the coming year, overlooking the snowy plateau, Mount Everest is covered with snow, and the scenery is infinite. The Yarlung Zangbo River turns the sincerity of spring, summer and autumn into the best wishes, flowing to the north and south of the motherland, with snow lotus in Tianshan Mountain and red beans in Nanshan Mountain. Give a sonorous chrysanthemum from Ao Shuang. May winter be warm, happy, happy and sweet, and all your wishes come true, and you will be bathed in bright sunshine. May your career flourish, stand by the river, brew ancient poems, stand in the cold smoke of the residual leaves, hold hands and look at each other, face the sunshine in the flowers of the years, and thousands of bloom flowers, with different kinds of red and unique flowers, will dry up.

Autumn is deep, the withered flowers have faded their red makeup, the autumn water is silent and lonely, the ink stains a pool of ghosting, and the strings are cool. Yesterday's stunning city was placed in silence, and a lost fragrance precipitated glitz, temporarily hiding the silent seeds in the moss under the waves. When the ice and snow melt and meet again, on a pool of clear water, the white lotus blooms and then opens the pavilion. Looking at the breeze, the residual capacity condenses, accompanied by the healing fragrance, and the dream of rebirth will erupt quietly. How many beautiful ink marks will be left in past lives near a pool of residual lotus dreams, and the eyes will be blown dry by the wind and the heart will be washed away. Walking with Winter Girl in nature is also a kind of pride, which relaxes the mind and cherishes it. Collected in my memory, at this moment, in my eyes, there is only winter, only the warm sun. She is simple and complicated, simple and profound, breathing fresh air and embracing the innocence and simplicity specially endowed by nature.
