Global Energy Interconnection
The Global Energy Interconnection is a proposed global electricity network (Super grid). Idea Conception The proposal is an eighteen-line backbone of ultra high voltage connections to link 80 countries in networks incorporating smart-grid technology and significant renewable energy sources. The scope of the proposal spans 50 years. The first phase focuses on integrating national grids, building new smart grids, and increasing renewable energy usage. The second phase would connect continental grids. The third phase, proposed for the period 2030 to 2070, would develop Afro-Eurasian transcontinental grids linked by ultra high voltage systems. The idea was conceived by State Grid Corporation of China (SGCC), and put forward by SGCC Chairman Liu Zhenya, at a workshop on November 12, 2015. President Xi Jinping supports the proposal and has linked it to the principle of ecological civilization and highlighted it in international forums including a 2015 speech before the UN General A ...

Electricity Network
An electrical grid (or electricity network) is an interconnected network for electricity delivery from producers to consumers. Electrical grids consist of power stations, electrical substations to step voltage up or down, electric power transmission to carry power over long distances, and finally electric power distribution to customers. In that last step, voltage is stepped down again to the required service voltage. Power stations are typically built close to energy sources and far from densely populated areas. Electrical grids vary in size and can cover whole countries or continents. From small to large there are microgrids, wide area synchronous grids, and super grids. The combined transmission and distribution network is part of electricity delivery, known as the ''power grid''. Grids are nearly always synchronous, meaning all distribution areas operate with three phase alternating current (AC) frequencies synchronized (so that voltage swings occur at almost the same tim ...

Super Grid
A super grid or supergrid is a wide-area transmission grid (electricity), network, generally trans-continental or multinational, that is intended to make possible the trade of high volumes of electricity across great distances. It is sometimes also referred to as a "mega grid". Super grids typically are proposed to use high-voltage direct current (HVDC) to transmit electricity long distances. The latest generation of HVDC power lines can transmit energy with losses of only 1.6% per 1,000 km (621.4 miles). Super grids could support a global energy transition by smoothing local fluctuations of wind energy and solar energy. In this context they are considered as a key technology to Climate change mitigation, mitigate global warming. History The idea of creating long-distance transmission lines in order to take advantage of renewable sources distantly located is not new. In the US in the 1950s, a proposal was made to ship hydroelectric power from dams being constructed in the P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
High-voltage Power Line Grid Of The World
High voltage electricity refers to electrical potential large enough to cause injury or damage. In certain industries, ''high voltage'' refers to voltage above a certain threshold. Equipment and conductors that carry high voltage warrant special safety requirements and procedures. High voltage is used in electrical power distribution, in cathode-ray tubes, to generate X-rays and particle beams, to produce electrical arcs, for ignition, in photomultiplier tubes, and in high-power amplifier vacuum tubes, as well as other industrial, military and scientific applications. Definition The numerical definition of depends on context. Two factors considered in classifying a voltage as high voltage are the possibility of causing a spark in air, and the danger of electric shock by contact or proximity. The International Electrotechnical Commission and its national counterparts (IET, IEEE, VDE, etc.) define ''high voltage'' as above 1000 V for alternating current, and at ...

Ultra-high-voltage Electricity Transmission In China
Ultra-high-voltage electricity transmission (UHV electricity transmission) has been used in the People's Republic of China since 2009 to transmit both alternating current (AC) and direct current (DC) electricity over long distances separating China's energy resources and consumers. Background Since 2004, electricity consumption in People's Republic of China has been growing at an unprecedented rate due to the rapid growth of industrial sectors. Serious supply shortage during 2005 had impacted the operation of many Chinese companies. Since then, China has very aggressively invested in electricity supply in order to fulfil the demand from industries and hence secure economic growth. Installed generation capacity has run from 443 GW at end of 2004 to 793 GW at the end of 2008. The increment in these four years is equivalent to approximately one-third of the total capacity of the United States, or 1.4 times the total capacity of Japan. During the same period of time, annual ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Renewable Energy In China
China is the world's top electricity producer from renewable energy sources. China's renewable energy capacity is growing faster than its fossil fuels and nuclear power capacity. China Installed over 373 GW of renewables in 2024, reaching a total installed renewable capacity of 1,878 GW by the end of the year. The country aims to have 80% of its total energy mix come from non-fossil fuel sources by 2060, and achieve a combined 1,200 GW of solar and wind capacity by 2030. Although China currently has the world's largest installed capacity of hydro, solar and wind power, its energy needs are so large that renewable sources provided only 29.4% of its electricity generation in 2021. The share of renewables in total power generation is expected to continue increasing to 36% by 2025, in line with China's pledge to achieve carbon neutrality before 2060 and peak emissions before 2030. China sees renewables as a source of energy security and not only a means to redu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Energy Policy Of China
The People's Republic of China is both the world's largest energy consumer and the largest industrial country. Since the country's industrialization in the 1960s, China is currently the world's largest emitter of greenhouse gases, and coal in China is a major cause of global warming. China is also the world's largest renewable energy producer (see this article), and the largest producer of hydroelectricity, solar power and wind power in the world. The energy policy of China is connected to its industrial policy, where the goals of China's industrial production dictate its energy demand management. Being a country that depends heavily on foreign petroleum import for both domestic consumption and as raw materials for light industry manufacturing, electrification is a huge component of the Chinese national energy policy.
