A new world record on clean energy has been set by China’s Qinghai – 82.9% of energy generated in the first half of 2019 in Qinghai, a province in Northwest China, is of clean energy which means these energies are from wind, solar, hydro and/or geothermal.
In June this year, Qinghai did an amazing clean energy test to use only clean energy for 15 consecutive days. From 02:00 6/9/2019 to 24:00 6/23/19, all energies consumed within Qinghai province are clean energies. With 290,00 square miles and 550 million population, the test is the largest clean energy test in human history.
Qinghai locates at Northwest China where it has abundant wind and solar resources. in 2018, Qinghai’s wind energy installed capacity has surpassed that of hydropower, and became the largest power source for the province. Two more million kilowatt-class wind energy bases are currently under construction.
Wind energy is the use of air flow through wind turbines to provide the mechanical power to turn electric generators and traditionally to do other work, like milling or pumping. Wind power is a sustainable and renewable alternative to burning fossil fuels, and has a much smaller impact on the environment. China has been rapidly expanding its wind installations, mostly in Northwest China, in the late 2000s and passed the United States in 2010 to become the world leader.
Qinghai is sparsely populated with flat terrain. The unused desertification land covers an area of over 38,610 square miles (larger than South Korea) which can be used to build large-scale grid-connected photovoltaic power station.The large magnitude of solar energy available in Qinghai makes it a highly appealing source of electricity. Qinghai has the largest solar energy installed capacity in whole China.
Another energy source worth nothing is geothermal. While geothermal energy development in Qinghai is still at very early stage, Cilitech expects there will be significant increase in the sector in the near future. Three types of geothermal resources have been discovered in Qinghai that includes underground hot water, shallow geothermal energy, and dry hot rock.
In August 2017, Geological Survey Bureau of China drilled 236°C high-temperature dry-heat rock mass at a depth of 3,705 meters in the Gonghe Basin in Qinghai. The discovery is a major breakthrough in the exploration of dry and hot rock not only in China but also in the world. It is estimated that the recoverable reserves of geothermal energy within China, mostly in Qinghai and Tibet, is equivalent to 12 trillion tons of oil, 50 times of world proved oil reserves.
