Planning of the grid integration of wind energy in Germany onshore and offshore up to the year 2020
The ongoing penetration of large amounts of wind power capacities in Germany has strong impacts on the necessary promotion volumes (direct costs of Renewable Energy Source (RES) promotion) but also on necessary grid extensions, the future need for regulating and reserve power capacities, the thermal power plant system and the electricity price for end-consumers (indirect effects). On behalf of ...

Regional electricity price differences due to intermittent wind power in Germany: impact of extended transmission and storage capacities
A fast growth of installed wind power capacity has been experienced in several European countries. In Germany, notably high wind power capacities are planned in the North. If the existing transmission capacities between individual regions become insufficient, the electricity prices will differ considerably and the system operation can become unstable. It is supposed that the extension of ...

Global wind power capacity reaches 100,000MW
At its current growth rate, global installed wind power capacity will top 100,000 megawatts in March 2008. In 2007, wind power capacity increased by a record-breaking 20,000 megawatts, bringing the world total to 94,100 megawatts—enough to satisfy the residential electricity needs of 150 million people. Driven by concerns regarding climate change and energy security, one in every three countries ...

Wind energy development in China: institutional dynamics and policy incentives
China is endowed with rich wind resources. During the early 1990s, China's wind power capacity grew at an average annual rate of 50%. Total installed wind farm capacity reached 344.8 MW by 2000. However, the pace of wind power development has slowed down in recent years. Through economic analysis and identification of the institutional barriers that led to the rise and fall of wind energy ...

Wind in power 2014 European Statistics
Wind power capacity installations During 2014, 12,819.6 MW of wind power was installed across Europe, of which 11,791.4 MW was in the European Union. Of the capacity installed in the EU, 10,308.1 MW was onshore and 1,483.3 MW offshore. In 2014, the annual onshore market increased in the EU by 5.3%, and offshore installations decreased by 5.3% compared to 2013. Overall, EU wind energy annual ...

Wind Tops 10 Percent Share of Electricity in Five U.S. States
A new picture is emerging in the U.S. power sector. In 2007, electricity generation from coal peaked, dropping by close to 4 percent annually between 2007 and 2011. Over the same time period, nuclear generation fell slightly, while natural gas-fired electricity grew by some 3 percent annually and hydropower by 7 percent. Meanwhile, wind-generated electricity grew by a whopping 36 percent each ...

Why the fossil-fuelled reactor fleet in France will not be affected by an evolution of the wind power capacity
Today's power electronics can confer high-performance adjustment capabilities on any technological object, including the frequency-power and voltage tuning of modern, synchronous-type wind turbines. However, this will not enable such devices to steadily produce electric power from an uncontrolled mechanical energy. Thus they cannot be considered independent generation units: the need to ...

The price of wind energy in the U.S. hits an all-time low
States hoping to increase their share of renewable energy to achieve the emissions reduction goals set forth in the President’s recently-announced Clean Power Plan may have just received an unexpected boost from wind energy. According to the U.S. Department of Energy’s “2014 Wind Technologies Market Report” released earlier this week, the prices offered by wind projects ...

Wind power is about to get a whole lot cheaper
Wind energy is soaring around the world, thanks to technology advances and energy policies that have reduced its cost. And things are only going to get better — with prices dropping substantially by mid-century, according to a survey of 163 of the world’s leading wind energy experts. The results, published in the journal Nature Energy, suggest that the cost of electricity from wind ...

Taonan case study
Working to decarbonise China's energy future Located in Taonan, Jilin Province, north east China, this 49.3 MW grid connected wind farm demonstrates the economic viability of wind power technology in a region where, until now, it has been seen as marginal. The project generates over 100,000 MWh of electricity per annum, and delivers greenhouse gas emission reductions equal to 92,508 tCO2e per ...

Energy and exergy assessments for potential wind power in Turkey
The main objective of the study is to estimate wind power potential of Turkey and provide suitable data for evaluating potential wind power by using the wind data collected at 23 different wind-monitoring stations. In this study, energy and exergy analyses of wind power are used to estimate wind power potential in these areas. Exergy analysis of wind power is investigated according to air ...

World Wind Power Poised to Bounce Back after Slowing in 2013
At the end of 2013, the wind farms installed in more than 85 countries had a combined generating capacity of 318,000 megawatts, which would be enough to meet the residential electricity needs of the European Union’s 506 million people. New data from the Global Wind Energy Council show that wind developers built 35,000 megawatts of new generating capacity worldwide in 2013. This was down ...

World Nuclear Electricity Generation Down 5 Percent Since 2006
World nuclear electricity-generating capacity has been essentially flat since 2007 and is likely to fall as plants retire faster than new ones are built. In fact, the actual electricity generated at nuclear power plants fell 5 percent between 2006 and 2011. In 2011, following Japan’s Fukushima Daiichi nuclear disaster, 13 nuclear reactors in Japan, Germany, and the United Kingdom were ...

Iowa and South Dakota Approach 25 Percent Electricity from Wind in 2012: Unprecedented Contribution of Wind Power in U.S. Midwest
Defying conventional wisdom about the limits of wind power, in 2012 both Iowa and South Dakota generated close to one quarter of their electricity from wind farms. Wind power accounted for at least 10 percent of electricity generation in seven other states. Across the United States, wind power continues to strengthen its case as a serious energy source. The United States now has 60,000 ...

Reducing avian collisions with wind turbines
Wind is an important renewable energy source for Europe. The wind power capacity installed in 2014 could produce enough electricity to meet over 10% of the EU’s electricity consumption. However, wind power structures can also be harmful to birds, which can collide with turbines. This study assessed methods of reducing avian collisions with wind turbines and makes several practical ...

Wind Surpasses Nuclear in China
Wind has overtaken nuclear as an electricity source in China. In 2012, wind farms generated 2 percent more electricity than nuclear power plants did, a gap that will likely widen dramatically over the next few years as wind surges ahead. Since 2007, nuclear power generation has risen by 10 percent annually, compared with wind’s explosive growth of 80 percent per year. Before the March ...
