consumption of energy is unavoidable, China must take steps to change the form of its economic growth and increase substantially the energy efficiency of industry and society. Among other things, China should find new points of economic development that move it away from being the "World's Factory" and improves energy efficiency. It also must avoid unnecessary waste, foster a sustainable economy and encourage renewable energy to reduce its reliance on petrochemical energy resources. Since June 2006 when Chinese Premier Wen Jiabao visited the Shenhua Group's coal liquefaction project and expressed that coal-to-liquids production was one important part of China's energy security, there have been many new 'coal to oil' projects announced by many large coal producing provinces and cities. As of the end of 2006, 88 methyl alcohol projects were planned; their total was 48.5 megatons/year. By 2019, methyl alcohol output reached 69.9 megatons/year. This rapid development to build coal to oil projects prompted concerns about wasteful development and unintended consequences; these include wasteful extraction of coal, excessive water use (this process requires 10 tons of water for every ton of oil produced), and likely increases in coal prices. China and Russia are linking their electric power networks so that China can buy power from the Russian Far East to supply Northeast China (Dongbei) and thus conserving domestic resources, lowering energy consumption, lessening China's dependence on imported oil (80%–90% of which must be shipped through unsafe waters), and reducing pollution discharge. Multiple long-distance high-tension, high-capacity line for international transmission have been built, including a 110kV transmission project, and three others with 220kV, 220kV, and 550kV. China also is considering connecting its power transmission lines with Mongolia and several former Soviet states that border China. Until 2020, Russia exported a total of 30.42 TWh electricity to China, decreasing coal consumption in the latter by 10.17 million tons. By importing electricity China not only reduced its dependence on imported crude oil, but also enhanced energy security by diversifying its foreign energy sources, making China less vulnerable to disruptions in supply. In 2021 a total of 8571.4 TWh of electricity was generated in China, up from 7814.3 in 2020, from an installed base of 2380 GW of power generating capacity, 12.6% among which from windpower sources and 12.2% from solar sources. Challenges There are significant logistical challenges to renewable energy in China. One such issue is grid connections from renewable energy power plants
