Gigawatt
The watt (symbol: W) is the unit of power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantify the rate of energy transfer. The watt is named after James Watt (1736–1819), an 18th-century Scottish inventor, mechanical engineer, and chemist who improved the Newcomen engine with his own steam engine in 1776. Watt's invention was fundamental for the Industrial Revolution. Overview When an object's velocity is held constant at one metre per second against a constant opposing force of one newton, the rate at which work is done is one watt. : \mathrm In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere (A) flows across an electrical potential difference of one volt (V), meaning the watt is equivalent to the volt-ampere (the latter unit, however, is used for a different quantity from the real power of an electrical circuit). : \m ...

Renewable Energy In The European Union
Renewable energy plays an important and growing role in the energy system of the European Union. The Europe 2020 strategy included a target of reaching 20% of gross final energy consumption from renewable sources by 2020, and at least 32% by 2030.Share of renewables in energy consumption in the EU reached 18% in 2018 News Release, 23 January 2020. The EU27 reached 22% in 2020, up from 9.6% in 2004. These figures are based on energy use in all its forms across all three main sectors, the heating and cooling sector, the electricity sector, and the transport sector. The main sour ...

Hydroelectricity In Brazil
As of 2018, renewable energy accounted for 79% of the domestically produced electricity used in Brazil. Brazil relies on hydroelectricity for 65% of its electricity, and the Brazilian government plans to expand the share of wind energy (currently 11%), solar energy (currently 2.5%) and biomass as alternatives. Wind energy has the greatest potential in Brazil during the dry season, so it is considered a hedge against low rainfall and the geographical spread of existing hydroelectric resources. Brazil held its first wind-only energy auction in 2009, in a move to diversify its energy portfolio. Foreign companies scrambled to take part. The bidding lead to the construction of 2 gigawatts (GW) of wind production with an investment of about $6 billion over the following two years. Brazil's technical potential for wind energy is 143 GW due to the country's blustery kilometres coastline where most projects are based. The Brazilian Wind Energy Association and the government hav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydroelectricity In Canada
According to the International Hydropower Association, Canada is the fourth largest producer of hydroelectricity in the world in 2021 after the United States, Brazil, and China. In 2014, Canada consumed the equivalent of 85.7 megatonnes worth of oil of hydroelectricity, 9.8% of worldwide hydroelectric consumption. Furthermore, hydroelectricity accounted for 25.7% of Canada's total energy consumption (37.3% of non-oil sources). It is the third-most consumed energy in Canada behind oil and natural gas (30.9% and 28.1% of total consumption, respectively). Some provinces and territories, such as British Columbia, Manitoba, Newfoundland and Labrador, Quebec and Yukon produce over 90% of their electricity from Hydro. All of the dams with large reservoirs were completed before 1990, since then most development has been Run-of-the-river hydroelectricity, run-of-the-river, both large and small. Natural Resources Canada calculates the current installed small hydro capacity is 3,400 MW, with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydroelectricity In China
Hydroelectricity is currently China's largest renewable energy source and the second overall after coal. China's installed hydroelectric capacity in 2015 was 356 GW, up from 172 GW in 2009, including 23 GW of pumped storage hydroelectricity capacity. According to the International Hydropower Association China is the worlds largest producer of hydroelectricity in 2021. In 2018, hydropower generated 1,232 TWh of power, accounting for roughly 18% of China's total electricity generation. Due to China's insufficient reserves of fossil fuels and the government's preference for energy independence, hydropower plays a big part in the energy policy of the country. China's potential hydropower capacity is estimated at up to 400 GW. There is therefore considerable potential for further hydro development. Hydroelectric plants in China have a relatively low productivity, with an average capacity factor of 31%, a possible consequence of rushed construction and the seasonal variability of rain ...

Hydroelectric Power
Hydroelectricity, or hydroelectric power, is electricity generated from hydropower (water power). Hydropower supplies one sixth of the world's electricity, almost 4500 TWh in 2020, which is more than all other renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants.

Ground (electricity)
In electrical engineering, ground or earth is a reference point in an electrical circuit from which voltages are measured, a common return path for electric current, or a direct physical connection to the Earth. Electrical circuits may be connected to ground for several reasons. Exposed conductive parts of electrical equipment are connected to ground, to protect users from electrical shock hazard. If internal insulation fails, dangerous voltages may appear on the exposed conductive parts. Connecting exposed parts to ground will allow circuit breakers (or RCDs) to interrupt power supply in the event of a fault. In electric power distribution systems, a protective earth (PE) conductor is an essential part of the safety provided by the earthing system. Connection to ground also limits the build-up of static electricity when handling flammable products or electrostatic-sensitive devices. In some telegraph and power transmission circuits, the ground itself can be used as one condu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Power Outage
A power outage (also called a powercut, a power out, a power failure, a power blackout, a power loss, or a blackout) is the loss of the electrical power network supply to an end user. There are many causes of power failures in an electricity network. Examples of these causes include faults at power stations, damage to electric transmission lines, substations or other parts of the distribution system, a short circuit, cascading failure, fuse or circuit breaker operation. Power failures are particularly critical at sites where the environment and public safety are at risk. Institutions such as hospitals, sewage treatment plants, and mines will usually have backup power sources such as standby generators, which will automatically start up when electrical power is lost. Other critical systems, such as telecommunication, are also required to have emergency power. The battery room of a telephone exchange usually has arrays of lead–acid batteries for backup and also a socket ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
