The new report prepared by economics professor Gordon Hughes, a former advisor to World Bank, Dr Capell Aris, a fellow of the IET, and Dr John Constable of the Global Warming Policy Forum, explains how the broad assumption that offshore wind prices are falling is not valid. Through a detailed statistical analysis of the data, covering 86 wind farms, the authors found that capital cost of offshore wind (£/MWh installed) is actually rising as a consequence of companies moving into deeper and deeper waters. The summary of the report is provided below. The full report can be downloaded from this page.

Facts, analysis, exposure to industrial wind energy's real impacts
The pilot study carried out in Satakunta and Northern Ostrobothnia in Finland shows that the damage caused by infrasound from wind power plants will only decrease significantly more than 15 kilometers away from wind turbines. The study was carried out by the Finnish Association for Environmental Health (SYTe) in the spring 2016. A portion of the study's results is provided below. The full report (in English) can be found at the document links on this page.

This paper is one of the first to report on the mortality of insects due to wind turbines. The summary of the paper is provided below. The full paper can be accessed at the document links on this page.
This paper examines the issues involved in deciding whether an operating wind project in Europe is likely to be repowered as the facility approaches its end of life. The document can be downloaded from this page. The paper's abstract and concluding paragraphs are excerpted and provided below.
The United Kingdom has has taken steps to reduce the financial burden of supporting renewable energy in the country. The Government introduced its new Low Carbon Levies (LCL) framework which was designed to control the cost of supporting low carbon electricity paid by consumers on their electric bills. The plan addresses the costs of the 'Contracts for Difference' (CFD), the 'Renewable Obligation' (RO) and the 'Feed in Tariff Scheme' (FiTs). The government asserted that it will monitor the total cost of these programs and, "Until the total burden of these costs is forecast to fall in real terms over a sustained period, the Control will not allow for new low carbon electricity levies to be introduced. Based on the current forecast, ...this will rule out new levy spend until 2025." The portion of the Government document is provided below.

FINLAND. Aunio Group Oy from Oulu has developed a device for measuring and recording infrasound produced by wind turbines. The measurement equipment can be used to produce research data for investigating the characteristics of infrasound and where it spreads, and to analyze any health problems it may cause. The infrasound produced by wind turbines differs from infra-sounds occurring in nature; according to measurements the infrasound produced by wind turbines is a clear signal - distinguishable from ambient noise in the environment. This paper describes the method of evaluating the Anuio Group's device and the results. The full paper can be accessed by clicking the links on this page.
On December 24, 2015, a Vestas wind turbine collapsed in Lemnhult, Sweden. More than a year later, the Swedish Accident Investigation Authority has launched its report. The full report, in Swedish, can be accessed by clicking the links on this page. An English summary which is also provded in the report is posted below. Images of the collapsed Vestas V112 turbine can be found here.
Abstract
This important research identified that migrating raptor species tend to be attracted to offshore wind turbines and that the risk of colliding with wind turbines at sea is much greater than previously assumed. The abstract and resulting discussion of the paper are provided below. The full paper can be downloaded by clinking the links on this page.
Summary
This paper argues that the methods and data used when estimating effects of offshore wind turbines on seabird population rates and the potential impacts on seabird populations are grossly inadequate. As a result, Environmental Impact Assessments cannot solely be relied on to report risks. The conclusions cited in the paper are provided below.

The European Court of Justice has ruled against Bulgaria in a case brought by the European Commission against the country over its failure to protect unique habitats and important species in the Kaliakra special protection area at the Black Sea coast, the court announced on January 14 2016. Projects such as wind turbines, a golf course, spa and hotels have been approved and built in the area by Bulgarian authorities, despite the likelihood it would lead to significant disturbance of these protected species. As a result, the court has found Bulgaria to be breaching the EU’s Birds and Habitats Directives. A portion of the ruling is below. The full decision can be accessed by clicking the links on this page.
This decision letter issued by the United Kingdom energy secretary reports that the Mynydd y Gwynt wind energy proposal has been denied. Reasons for the denial include the secretary's inability to determine the project's impact on red kites resident at the Elenydd-Mallaen special protection area (SPA). A portion of the decision is provided below. The full document can be accessed by clicking the links on this page. The project would have sited 27 turbines of between 3 MW and 3.3 MW each in Powys.
