Whitelee Wind Farm – Introduction

Whitelee wind farm is the largest onshore wind farm in Europe, with 140 Siemens wind turbines and a total capacity of 322 megawatts (MW). Whitelee was developed and is operated by ScottishPower Renewables, which is part of the Spanish company Iberdrola. Positioned 370 metres (1200 feet) above sea level and 15 kilometres (9 miles) outside [...]

Severn Barrage – Environmental impact

The Severn Estuary is a Special Area of Conservation due to the European importance of its ecology. The inter-tidal area provides food for over 85,000 migratory and wintering water birds, and represents 7% of the UK’s total estuaries. There are nature reserves and Site of Special Scientific Interest (SSSI) on the islands of Flat Holm [...]

Prairie Hills Motorsports Club – Facility Design

Noted race track architect [http://www.paxtonwatersarchitecture.com/ Paxton Waters] is in the final stages of designing the complete facility. His design will include a prominent hotel, conference center, restaurant, spa, retail space, garages, condominiums, karting track, and a 6,000 to 8,000 seat amphitheater for concerts. Duke Energy also has agreements to erect 240-foot-tall wind turbines on part [...]

Cape Wind – Controversy

Supporters of the project, led by the non-profit grassroots organization Clean Power Now, cite wind’s ability to displace oil and gas consumption with clean, locally produced energy and claim the project is the best option for much needed new generating capacity in the region. It would supply 75% of the average electrical needs of Cape [...]

NaREC – Operations

POWER cluster – Offshore wind power

Compared to onshore wind power, offshore wind power is more complex and costly to install and maintain but also has several key advantages. Winds are typically stronger and more stable at sea, resulting in significantly higher production per unit installed. Wind turbines can also be bigger than on land because it is easier to transport [...]

Microgeneration – Microgeneration as integrated part of domestic self-sufficient system

Microgeneration can be integrated as part of a self-sufficient house and is typically complemented with other technologies such as domestic food production systems (permaculture and agroecosystem), hydrogen or other extra electricity generation systems for self-sufficient transport, rainwater harvesting, composting toilets or even complete greywater treatment systems. Domestic microgeneration technologies include: photovoltaic solar systems, small scale [...]

Wind power in Texas – Large wind farms

Roscoe Wind Farm (781 MW) The Roscoe Wind Farm in Roscoe, Texas is the world’s largest wind farm (as of September 2009) with 627 wind turbines and a total capacity of 781 MW, which is enough to power more than 250,000 average Texan homes. Horse Hollow Wind Energy Center (735 MW) The Horse Hollow Wind [...]

Yaw drive – Introduction

Wind Energy

yaw drive is an important component of the horizontal axis wind turbines’ yaw system. To ensure the wind turbine is producing the maximal amount of electric energy at all times, the yaw drive is used to keep the rotor facing into the wind as the wind direction changes. This only applies for wind turbines with [...]

High-voltage direct current – Applications

Overview The controllability of current-flow through HVDC rectifiers and inverters, their application in connecting unsynchronized networks, and their applications in efficient submarine cables mean that HVDC cables are often used at national boundaries for the exchange of power (in North America, HVDC connections divide much of Canada and the United States into several electrical regions [...]

Power station – Other sources of energy

Tidal Energy

Other power stations use the energy from wave or tidal motion , wind, sunlight or the energy of falling water, hydroelectricity. These types of energy sources are called renewable energy. Hydroelectricity Dams built to produce hydroelectricity impound a reservoir of water and release it through one or more water turbines, connected to generators, and generate [...]

Wind power in the Netherlands – Onshore Wind Power

Wind Power

In December 2009, a total of 1,879 onshore wind turbines were installed in the Netherlands, compromising a total of 1,993 MW. The largest onshore wind farm is located in Eemshaven in Groningen, in the north of the Netherlands. This 204 MW wind farm contains 21 Vestas V90 3MW (known as GroWind) and 47 Enercon E [...]
