Analysis of vertical wind shear in the Southern Great Plains and potential impacts on estimation of wind energy production
This paper describes the analysis of near-surface wind speeds in Western Oklahoma. The goals of this research are to characterise the nocturnal low-level jet (LLJ) in the region, and to assess the impact wind variability, vertical shear and the LLJ on wind energy calculations. Results show the seasonal variability in wind characteristics as well as in the vertical wind shear, and also illustrate ...

Wind Energy Production Estimates: Moving Beyond Time Averages
No need to be a statistician to see that averages are often useful to compare different things. And yet, they often fall short as a true measure of performance. For instance, we use averages to compare the current weather against the climate normals or to get a sense of how our favorite sport team or player is doing. Team (player) statistics are a concise way of combining the scores from many ...

Forecasting Exercise - Case Study
Objective: In 2005, AEE promoted a project related to the prediction of wind farm energy production, known as the Prediction Exercise. The project was financed by AEE and by companies that own the parks, as well as by a subsidy from the PROFIT programme of the Ministry of Education and Science. The Prediction Exercise consisted of a comparative Round Robin of ...

Global wind speeds bounce back to hike output; New Jersey raises offshore target to 7.5 GW
Global onshore wind speeds are rising, new study finds Global onshore wind speeds have risen since 2010, after decades of decline, boosting potential wind energy by around 17% between 2010 and 2017, according to a new academic study published in Nature. Rising wind speeds have increased U.S. wind turbine capacity factors by around 2.5% since 2010, representing half the gains in capacity ...

Productivity of small wind turbines for various wind potentials conditions: application in Bulgaria and Corsica
Less or more accurate power curve models are generally used to simulate the wind turbine electrical production versus the available wind speed. However, if such models are adapted to large machines, this is not the case for small ones. The objective of this paper is to study the impact of different small-scale wind turbines power curves and wind distributions on the electrical production. An ...

Wind farms benefting the region
Wind farms as close as Benton and White counties—and others around the world—are boosting Tippecanoe County’s economy by at least $20 million a year, reports Jody Hamilton, director of economic development for Greater Lafayette Commerce. “From land title searches to construction labor and turbine components, businesses in Greater Lafayette are enjoying new revenues, and that figure doesn’t ...

Optimizing Wind and Solar Power in Africa
Editor's Note: The following is a news release authored by Julie Chao and issued by Lawrence Berkeley National Laboratory on April 5, 2017 To meet skyrocketing demand for electricity, African countries may have to triple their energy output by 2030. While hydropower and fossil fuel power plants are favored approaches in some quarters, a new assessment by the Department of Energy’s Lawrence ...

We learn how to finance a renewable energy project
At the 12th annual Canadian-German wind and solar energy conference, it's all about dollars and cents It’s no secret that the Germans have done a lot right when it comes to renewable power. They have some of the highest renewable capacity in the world! So, for a fledgling renewable market like Alberta, the 12th Annual Canadian-German Wind and Solar Energy Conference, held March 23 in ...

Comparative life cycle assessment of 2.0 MW wind turbines
Wind turbines produce energy with virtually no emissions, however, there are environmental impacts associated with their manufacture, installation, and end of life. The work presented examines life cycle environmental impacts of two 2.0 MW wind turbines. Manufacturing, transport, installation, maintenance, and end of life have been considered for both models and are compared using the ReCiPe 2008 ...

Using Thermal Insulation in Offshore Wind Farms
Thermal insulation reduces the transfer of thermal energy between objects which have different temperatures or are within range of radiative influences. Heat flow is an inevitable outcome when objects of different temperatures interact. Thermal insulation provides a region in which thermal conduction is reduced or thermal radiation is reflected by the lower-temperature ...

An introduction to reactive power compensation for wind farms
The paper summarises the refereed contributions of seven articles reviewed for publication in the IJETP – Special Issue on "Reactive compensation for wind farms". The main goal of the special issue is to provide a forum to exchange information on the reactive power compensation requirements for wind farms and introducing possible price mechanisms for today's deregulated power industry. ...

Wind turbines and health
The American Lung Association's agenda for the new administration, Protect the Air We Breathe: An Agenda for Clean Air, states: "Climate, energy and clean air are inexorably linked. Solutions that lead to cleaner air must be included in any approach to cleaner, more efficient energy use and reductions in global warming." 1 Wind energy is one such solution - a clean energy source that can ...

How can we ensure the race for clean energy doesn’t leave the world’s poorest citizens behind?
As in other places around the world, Mexico’s wind boom runs the risk of bypassing the poor, which is why we need new global standards. Wind power is booming in Mexico. With more than 3,200 megawatts in operation, the country is on par with Japan. By 2018 it expects to have 10,000 MW installed as part of the government’s Climate Action Plan. Promising, right? Scratch the surface of ...

9 reasons not to be depressed about the planet
From a sustainable future market perspective, it’s been a very good year. Don’t leave 2014 without realizing there have been notable — often underreported — big capital market breakthroughs on climate change, water protection and other sustainability fronts. Stock exchanges requiring company disclosure on sustainability risks or bonds backed by electricity payments from ...

Sustainable Electricity: One Step Closer to a Green Future
The continuous rise in carbon dioxide emissions for the last 30 years has led to increased atmospheric temperatures today. And the environment is getting more and more polluted due to the rapid industrialization and usage of fossil fuels for energy production. That is why there is a growing global demand for sustainable electricity, ensuring access to clean and affordable energy in order to stop ...

The effect of ocean waves on offshore wind turbines
The Ocean has a varying surface roughness where the roughness length is determined by the characteristics of the waves. In this paper, a method is established where the roughness length of the ocean is calculated from the wind speed and the fetch length. The fetch length depends on the wind direction and a case study is performed for a wind turbine exposed to wind blowing in two opposite ...

Senate passes bill extending energy tax credits
On July 21, 2015, the Senate Finance Committee voted to pass a $96 billion package of tax extenders. The tax credits in the package include Individual Tax Extenders, Business Tax Extenders, and $16.4 billion in Energy Tax Extenders. The wind production tax credit, a $1.01 per-gallon production credit for second generation biofuels, energy efficiency credits, and a renewable electricity production ...

The institutional co-evolution in diffusion of hydroelectric power technology
The introduction and significant momentum on diffusion of wind power as a new technology for energy production involve a push for changing the institutional framework in the energy sector. The introduction of hydro (electric) power technology and the following institutional change process may be compared to the introduction of wind power 90 years later. In this paper, the main focus is on the ...
