Is Wind Energy Actually Sustainable? Wind energy is usually considered a cleaner alternative to traditional sources of fossil fuel and is renewable, with much-reduced carbon emissions. However, its full range of implications is worth considering. Any discussion on the sustainability of wind energy necessarily involves wind turbine technology, recycling, and natural effects. Let’s explore ...

Decarbonization of the power sector plays a key role in achieving climate neutrality and net-zero targets in line with the 1.5ºC goal of the Paris Agreement. Therefore, the rapid transformation from fossil to renewable energy sources such as wind or solar is becoming increasingly important and crucial for countries aiming for ambitious climate targets. Despite the global pandemic, the ...
Customer: SNIM Wind Turbine: 16 Vergnet GEV MP-C, 275kW, 32m rotor diameter, 55m hub height Total power: 4.4 MW Commissioned: 2011 Operations and Maintenance: SNIM Vergnet GEV MP Wind Turbines Deliver Energy and Cost Savings for SNIM Iron Mine Société Nationale Industrielle et Minière (SNIM), Africa’s second largest producer of iron ore, ...
Intense competition in the wind market is spurring turbine developers to find new ways to improve performance and minimize costs. ...
The Problem: Management of Complex Systems The school’s energy resources include a biodiesel production facility, several large photovoltaic arrays, several solar thermal systems, a wind turbine, a geothermal system, and biomass heating. ...
Below, we illustrate Germany’s position on energy storage batteries, given it is a country with a high level of renewable power (27.3% of national energy mix (2014), according to german think-tank Agora Energiewende. Call for more Distributed Wind? Distributed Wind is typically a single or small number of wind ...
This paper presents the development and qualitative validation of a doubly-fed induction generator (DFIG) wind turbine model that is represented in terms of behaviour equations of each of the subsystems, mainly the turbine rotor, the drive train, the induction generator, the power converters and associated control systems and a ...
This paper studies the 'catching–up' process of China's emerging wind turbine manufacturing ecosystem, and analyses the dynamics of the shifting collaborative innovation network for the period 1980–2011. We have focused on the leading wind turbine manufacturers [i.e., manufacturers of entire wind ...
In the present scenario, the development of multilevel inverter is becoming popular for industrial applications and higher scale renewable green power technologies such as fuel cell, PV cell and wind turbine systems connected to the load. But the traditional multilevel topologies have large components and complex Pulse Width Modulation (PWM) ...
In this paper, data–driven system modelling, control, and fault detection technique for wind turbine systems are researched. ...
Without a doubt, wind power is taking the lead as not only a renewable energy with a much lessened environmental impact, but it is also edging out the competition from fossil fuels with the distinct ability to lessen the impact on the wallet. Fossil fuel consumption, headed by traditional fuel sources such as oil and natural gas, are falling to the way side as having a significant difference in ...
Using the Lagrange principle, the nonlinear dynamical equation of wind turbine generator drive system is presented, which considers nonlinear stiffness of the drive system. The stability of autonomous system is analysed by the Jacobian matrix. The stability of wind turbine ...
The aim of this researcher is to develop a complete wind central model driven doubly fed induction generator (DFIG) which feeds an AC power grid. ...
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 fed induction ...
Wind energy conversion systems (WECS) have merits as environmentally friendly and renewable sources of energy. ...
The actors are located in four 'nodes': scientific exploration, technological research, product creation, and market transitions. In the centre of CIM is the 'system entrepreneur' who is responsible for the managerial tasks within the innovation system. ...
Isolated wind farms employ simple squirrel cage induction generators driven by variable speed wind turbines. ...
In this paper, optimal control of new wind energy conversion scheme where four-leg improved matrix converter (MC) is used for performance and stability enhancement, particularly for sites where most of the time low wind speeds prevails, has been explained. The power factor at the interface with the grid is controlled by the MC to ensure purely active power ...
Legendary Texas oilman T. Boone Pickens is half right. We do need to harness this country's wind resources for a homegrown source of electricity, as he has been urging this summer in expensive television ads. And we do need to reduce the $700 billion we may soon be paying annually for imported oil. But part two of Pickens's plan--to move natural gas out of electricity production and use it to ...
Another is that fossil groundwater has been widely seen as inexhaustible. Two fresh water collecting systems are outlined here and it is argued that they have no ultimate limitation, either by the availability of water or by environmental constraints. The first system is the Water Road, with a large surface area so allowing distillation by solar and ...
