Energy In Wales
Energy in Wales (Welsh: ''Egni Cymru'') refers to the production of electricity in Wales. Electricity production In 2018, the annual production of electricity in Wales was 30.2 TWh and consumed 14.9 TWh, which means that Wales generates twice as much electricity as it consumes and is a net exporter of electricity to England, Ireland and Europe. In the same year, 25% was from renewable sources, up from 22% in 2017. Electricity generation encompasses a broad mix of technologies including Coal (e.g. Aberthaw), Gas (e.g. Baglan Bay), Wind ( Cefn Croes), hydro-electricity (Dinorwig), solar thermal/PV and biomass electricity. Fossil fuels Fossil fuels are not renewables; historically, the economy of Wales has been driven by fossil fuels. The coal industry in Wales had reached large proportions by the end of the eighteenth century, and then further expanded to supply steam-coal for the steam vessels that were beginning to trade around the world. The Cardiff Coal Exchange set the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wylfa Pano
Wylfa nuclear power station ( cy, Atomfa'r Wylfa) is a Magnox nuclear power station undergoing decommissioning. Wylfa is situated west of Cemaes Bay on the island of Anglesey, off the northwestern coast of Wales. Construction of the two 490MW nuclear reactors, known as Reactor 1 and Reactor 2, began in 1963. They became operational in 1971. Wylfa was located on the coast because seawater was used as a coolant. In 2012, Reactor 2 was shut down. Reactor 1 was switched off on 30 December 2015, ending 44 years of operation at the site. Wylfa Newydd (literally New Wylfa) was a proposed new nuclear station on a site adjacent to the old plant. An application to build two advanced boiling water reactors was submitted by Horizon Nuclear Power to the Office of Nuclear Regulation on 4 April 2017. , parent company Hitachi has withdrawn from the project. In 2022, the UK parliament expressed interests about the construction of a possible set of two EPR reactors on the site. History Wy ...

Renewable Energy
Renewable energy is energy that is collected from renewable resources that are naturally replenished on a human timescale. It includes sources such as sunlight, wind, the movement of water, and geothermal heat. Although most renewable energy sources are sustainable, some are not. For example, some biomass sources are considered unsustainable at current rates of exploitation. Renewable energy often provides energy for electricity generation to a grid, air and water heating/cooling, and stand-alone power systems. Renewable energy technology projects are typically large-scale, but they are also suited to rural and remote areas and developing countries, where energy is often crucial in human development. Renewable energy is often deployed together with further electrification, which has several benefits: electricity can move heat or objects efficiently, and is clean at the point of consumption. In addition, electrification with renewable energy is more efficient and therefore ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anglesey
Anglesey (; cy, (Ynys) Môn ) is an island off the north-west coast of Wales. It forms a principal area known as the Isle of Anglesey, that includes Holy Island across the narrow Cymyran Strait and some islets and skerries. Anglesey island, at , is the largest in Wales, the seventh largest in Britain, largest in the Irish Sea and second most populous there after the Isle of Man. Isle of Anglesey County Council administers , with a 2011 census population of 69,751, including 13,659 on Holy Island. The Menai Strait to the mainland is spanned by the Menai Suspension Bridge, designed by Thomas Telford in 1826, and the Britannia Bridge, built in 1850 and replaced in 1980. The largest town is Holyhead on Holy Island, whose ferry service with Ireland handles over two million passengers a year. The next largest is Llangefni, the county council seat. From 1974 to 1996 Anglesey was part of Gwynedd. Most full-time residents are habitual Welsh speakers. The Welsh name Ynys M ...

Tidal Lagoon Swansea Bay
Tidal Lagoon Swansea Bay was a proposed tidal lagoon power plant that was to be constructed in Swansea Bay off the south coast of Wales, United Kingdom. Development consent was granted by the UK government in June 2015, and in June 2018 the Welsh Government approved the plan and offered to invest £200 million; however, later that month the UK government withdrew its support on value-for-money grounds. Other options to enable the proposal to go ahead were reportedly still being explored. If built, the project would have become the world's first tidal lagoon power plant; other types of tidal power plants do exist. Initial project proposals The scheme is promoted by Tidal Lagoon (Swansea Bay) plc. According to the company, generation could operate 14 hours per day with a maximum output of 320 MW (nameplate capacity), enough to power around 155,000 homes. There are different ways to evaluate tidal energy output. The UK government considered intermittency due to the tides and that t ...

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.

Ffestiniog Power Station
The Ffestiniog Power Station () is a 360 megawatts pumped-storage hydroelectricity scheme near Ffestiniog, in Gwynedd, north-west Wales. The power station at the lower reservoir has four water turbines, which can generate 360 MW of electricity within 60 seconds of the need arising. The scheme has a storage capacity of around at maximum output for four hours, and the capacity to power the whole of North Wales for several hours. The station, commissioned in 1963, was the first major pumped storage system in the UK. The upper reservoir is Llyn Stwlan with a capacity of approximately which discharges of water to the turbine generators at the power station on the bank of Llyn Ystradau (Tanygrisiau reservoir). The building of the lower reservoir flooded the route of the Ffestiniog Railway which had to build a deviation around the reservoir and power station. The plant is operated by First Hydro, a UK company owned by a joint venture of International Power and Mitsui & Co., and has ...

Gwynedd
Gwynedd (; ) is a county and preserved county (latter with differing boundaries; includes the Isle of Anglesey) in the north-west of Wales. It shares borders with Powys, Conwy County Borough, Denbighshire, Anglesey over the Menai Strait, and Ceredigion over the River Dyfi. The scenic Llŷn Peninsula and most of Snowdonia National Park are in Gwynedd. Bangor is the home of Bangor University. As a local government area, it is the second largest in Wales in terms of land area and also one of the most sparsely populated. A majority of the population is Welsh-speaking. ''Gwynedd'' also refers to being one of the preserved counties of Wales, covering the two local government areas of Gwynedd and Anglesey. Named after the old Kingdom of Gwynedd, both culturally and historically, ''Gwynedd'' can also be used for most of North Wales, such as the area that was policed by the Gwynedd Constabulary. The current area is , with a population of 121,874 as measured in the 2011 Census. Et ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plas Tan Y Bwlch
Plas Tan y Bwlch in Gwynedd, Wales, is the Snowdonia National Park environmental studies centre, administered by the National Park Authority. It is located approximately east of the coastal town of Porthmadog, overlooking the valley of the River Dwyryd and the village of Maentwrog. The centre provides courses about the Snowdonia National Park and the surrounding region of Wales. History Plas Tan y Bwlch was built by the Oakeley family during the 19th century on the site of a first house probably built in the early 17th century. Additions designed by the Chester architect John Douglas were made to the house for W. E. Oakley in 1872. The nearby Oakeley Arms Hotel was also once part of the estate but was sold off in the early 20th century. The Oakeley family owned a huge slate quarry in Blaenau Ffestiniog from which slates were carried to Porthmadog by the Ffestiniog Railway which passed through the estate. Plas Tan y Bwlch is thought to be the first house in No ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tidal Power
Tidal power or tidal energy is harnessed by converting energy from tides into useful forms of power, mainly electricity using various methods. Although not yet widely used, tidal energy has the potential for future electricity generation. Tides are more predictable than the wind and the sun. Among sources of renewable energy, tidal energy has traditionally suffered from relatively high cost and limited availability of sites with sufficiently high tidal ranges or flow velocities, thus constricting its total availability. However, many recent technological developments and improvements, both in design (e.g. dynamic tidal power, tidal lagoons) and turbine technology (e.g. new axial turbines, cross flow turbines), indicate that the total availability of tidal power may be much higher than previously assumed and that economic and environmental costs may be brought down to competitive levels. Historically, tide mills have been used both in Europe and on the Atlantic coast of N ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wave Power
Wave power is the capture of energy of wind waves to do useful work – for example, electricity generation, water desalination, or pumping water. A machine that exploits wave power is a wave energy converter (WEC). Waves are generated by wind passing over the sea's surface. As long as the waves propagate slower than the wind speed just above, energy is transferred from the wind to the waves. Air pressure differences between the windward and leeward sides of a wave crest and surface friction from the wind cause shear stress and wave growth. Wave power is distinct from tidal power, which captures the energy of the current caused by the gravitational pull of the Sun and Moon. Other forces can create currents, including breaking waves, wind, the Coriolis effect, cabbeling, and temperature and salinity differences. As of 2022, wave power is not widely employed for commercial applications, after a long series of trial projects. Attempts to use this energy began in 1890 or earlier, ma ...
