Social representations of intermittency and the shaping of public support for wind energy in the UK
The practicality of UK renewable energy policy, given the potential impacts of intermittency, has been contested by expert institutions. At the same time, wind energy developments have engendered local controversy and civic campaign groups have emerged at local, regional and national levels. This research integrates these strands in exploring how intermittency is communicated to the public by ...

Multi-megawatt wind turbines for offshore use: aspects of Life Cycle Assessment
Life Cycle Assessment (LCA) is an instrument to quantify environmental impacts of the entire energy supply chain. According to the LCA, an appropriate indicator system should comprise all steps of a system's life cycle: production, operational and disposal processes ("cradle-to-grave"). Cumulative Energy Demand (CED) might be seen as one part of LCA as far as the depletion of energy resources in ...

Energetic and exergetic assessment of solar and wind potentials in Europe
This paper deals with a physics–based assessment of renewable energy potential in Europe, particularly solar and wind energy sources, using two literature models. A sensibility analysis with the weather data is first done. Actual temperature, pressure, relative humidity, global radiation and wind speed data are employed to develop energy and exergy maps for Europe, based on iso–areas of land–use. ...

US launches multi-million $ plan to kick start offshore wind industry
The new strategy from the Obama administration could challenge the UK’s place as world’s leading offshore wind energy hub. The US government unveiled yesterday a coordinated strategic plan to accelerate the development of offshore wind energy in a move that could ultimately challenge the UK's position as the world's leading offshore wind hub. Interior secretary Ken Salazar and energy ...

Dispatching of wind farms using battery energy storage
In this paper, a STATCOM interfaced battery energy storage system (BESS) is considered for smoothing intermittent power output of a large wind farm so that it can be dispatched. The main advantage of the system is that it can inject both real power (by charging/discharging the BESS) and the reactive power to the system. The paper investigates the main design issues related to BESS – the control ...

Novel STATCOM controllers for voltage stabilisation of wind energy scheme
This paper presents two novel dynamic controllers for the Static Synchronous Compensator (STATCOM) device to stabilise Stand-Alone Wind Energy Conversion Systems (SWECS) using an induction generator. The unified AC system wind energy conversion scheme is connected to a hybrid electric load. The STATCOM device is modelled using the PSCAD/EMTDC software environment. Two novel dynamic controllers ...

Reasons Available To Use Wind To Cater Energy Requirements
Excessive heating of the planet due to fossil fuel burning has forced people to look for green energy sources. That can be considered as the main reason why many people think of using wind power to cater their energy requirements. They are being used in large scale in areas such as Australia, USA, Spain, Denmark, India and Germany. Wind energy has its own advantages as well as disadvantages like ...

Are wind turbines economically viable in Britain?
If Britain establishes wind energy as their main energy source, they will be able to create a large number of new job opportunities. This can provide a huge influx of job opportunities in the short run since the implementation of wind turbines require a lot of manpower. Moreover, the maintenance of these wind farms can give life to a considerable amount of sustainable jobs. Monitoring the wind ...

Solar construction and retrofitting obligation for all buildings and structural systems?
Climate-active despite Brexit Great Britain has declared the "climate emergency" - just like London, Los Angeles, Oakland, Vancouver, Basel, now Constance - while in Germany even in some environmental protection circles there are discussions about whether the word should be used at all. And about what a “climate emergency” is supposed to mean and bring about. On the Brexit-shaken ...

Renewable Energy - A Key Solution to End Global Warming
Scientists have spent years trying to find the causes of global warming leading to significant changes in the world’s climate. Their research shows that several factors have contributed to the rise of earth’s temperature and altering of natural cycles and actions. One key reason is excessive emission of greenhouse gases like, methane and carbon dioxide (CO2) in the atmosphere. These ...

Reactive power compensation of wind energy conversion system by using Unified Power Flow Controller
Voltage control and reactive power compensation in a distribution network with embedded Wind Energy Conversion System (WECS) represents the main concern of this paper. The WECS is a fixed speed/constant frequency system that is equipped with an induction generator driven by an unregulated wind turbine. The problem is viewed from short-term (10 seconds), mid-term (10 minutes) and long-term (48 ...

Which is more efficient solar or wind energy?
Before we start our reasoning, we'd like to remind you that both are renewables, and therefore both are great energy options to turn to to improve our planet and to break our addiction to oil and gas. Today we will try to answer a question that we often ask ourselves when we are interested in renewable energies : between solar and wind energy, which is the most efficient? First, let's take a ...

A comparative study on the grid integrated wind energy conversion systems (WECS) using different generator models
A huge number of wind generators are going to be connected with the existing network in the near future. Therefore, it is necessary to analyse various models of wind energy conversion systems (WECS) for the purpose of studying the impacts upon grid. This paper presents comparative study on grid connected WECS having two different wind turbine generator systems (WTGS): model 1 [WTGS having doubly ...

Renewable Energy to secure our future
Clean energy is being talked about these years. From private blogs to various commercials, posters and mailings, people everywhere seem to be concerned about it. Even President Obama attached greater importance to a sustainable development than his predecessors. However, clean energy can refer to several subjects. What is clean energy referring to? How does clean energy benefit you? Does clean ...

An integrated assessment for wind energy in Lake Michigan coastal counties
The benefits and challenges of onshore and offshore wind energy development were assessed for a four‐county area of coastal Michigan. Economic, social, environmental, and spatial dimensions were considered. The coastal counties have suitable wind resources for energy development which could contribute toward Michigan's ten percent renewable energy standard. Wind energy is cost‐effective with ...

Asia-Pacific Analysis: Go green not nuclear
Crispin Maslog says the region should follow the Philippines' lead and focus on renewable, not nuclear power. A year after the Fukushima nuclear disaster, questions remain over the role of nuclear power in the developing world, including South-East Asia and the Pacific. Nuclear power had a renaissance, driven by rapidly growing energy demands, and fading memories of high-profile disasters at ...
