An outlook on determining trends in energy and related politics, courtesy of BBC Chartering.In the course of history, energy has always been a driving force for change. Nearly no other industry can claim having a more far-reaching effect on other industry sectors or society at large. The world is continually challenged to find answers to pressing questions surrounding energy supply, energy demand, and sustainability issues in the 21st century. In this article, we present seven megatrends which may continue to determine the energy political agenda in coming decades.Lower priority of ‘climate change' It seems obvious that the discussion regarding climate change has lost its momentum and fallen behind economic priorities. Currently, the top challenges are the global financial crisis, unemployment, and reforming the banking industry. Global leaders are using the term "climate change" less frequently and it seems this trend will continue. Other topics taking precedence are: economic growth, competitiveness, affordability of energy, and the security of energy supplies.This paradigm shift doesn't mean that climate change should disappear from the global agenda. It is part of our daily reality that millions of people, both in developing countries and developed urban areas, often reside under unbearable conditions caused by recurring floods

Regular contributors to PES, Kipp & Zonen are world renowned experts when it comes to providing class-leading instruments for measuring solar radiation. But what is important when it comes to selecting solar irradiance measurements equipment in solar energy projects? And what are the optimal solutions and systems for PV, CPV and CSP projects? We asked the company to provide readers with the definitive answers, including practical information on site prospecting and the efficiency monitoring of solar power plants.There are many questions when it comes to initial site prospecting. Where best to build a solar power plant? Which technology will have the lowest Levelized Cost of Energy (LCOE) and bring maximum return on investment (ROI)? What is the optimal size of the power plant on a given site? Well, knowing the amount and distribution of solar irradiance with low uncertainties will help to answer such questions. The amount of solar radiation available over time under the local environmental conditions is a key input for choosing the optimal location, technology and size of a solar energy project. Meanwhile, feasibility studies and technical due diligence calculations of a solar energy project always start with energy resource assessment.High precision on-site measurements of solar radiation

PES presents an exclusive, in-depth look at the pioneering projects and products of G. Lufft Mess- und Regeltechnik GmbH.Global cooperation with system partners requires a wide variety of different variants and interfaces. Lufft environmental sensors, whether stationary or mobile, can be integrated via many different protocols in new or existing applications.Through the low power consumption, the use of the WS compact weather sensor family from Lufft is altogether possible in the area of solar assessment as well as monitoring. Here, in particular, low installation and assembly efforts are appreciated.But how did Lufft start to evolve sensors for the solar industry?In the early nineties, Lufft used the radiation sensors from Haenni, Switzerland, to build into the first automatic weather stations. The silicon radiation sensor "Solar 130" was the first one to be used for the weather sensors. This specimen served as predecessor of the Lufft-own silicon pyranometer. While in the meantime, Haenni stopped the solar radiation sensor production and Lufft has started to work with Kipp & Zonen sensors - the world's leading pyranometer manufacturer.The weather sensor family has now grown and consists of a wide range of all-in-one solutions suitable for different customer needs. Four of the 18 WS versions

We head to DMG MORI's global headquarters in Winterthur, Switzerland, to discover more about the company's pioneering car charging system and its impact on energy efficiency.It is a widely discussed fact that electric vehicles only drive CO2 neutral when running on green power. Therefore an accessible charging infrastructure based on green energy is essential for the future of e-mobility. The whole infrastructure as shown in the e-charging station register of "goingelectric.de" includes 4,912 charging stations for Germany and 464 for Switzerland (status: 05.08.2015).In the United States the U.S. Department of Energy has registered 10,267 charging stations for electric vehicles. However it is not apparent how many of these stations are supplied by green power. It is striking, at least in the European context, how low the proportion of fast charging stations is. A mere 5% of the stations in Germany and 15% of the stations in Switzerland are listed as fast charging stations.Fast charging means that the charging terminal is capable of charging a vehicle at a rate of 22 kW or more. However, only fast charging stations that are able to provide 44 kW to 50 kW can charge electric vehicles like the VW e-Golf or the BMW i3,

Because they can withstand extreme environmental conditions, silicones are ideal for solar panel and photovoltaic (PV) applications. And while solar cells themselves are made of silicon, silicones are used during module assembly and installation as encapsulants, coatings, potting agents, adhesives and sealants. We present an overview and an interview, courtesy of Dow Corning.Dow Corning's latest PV-5802 Electrically Conductive Adhesive is a high performance and reliable silicone-based ECA for back contact PV modules, which helps increase long term sustainability and reduces the overall cost. This material technology can potentially be applied beyond back contact modules and bring benefits to our customers for other type of modules.Dr. Guy Beaucarne, Senior Application Engineer, will present a poster at the upcoming EUPVSEC event and will show the results of the study made with ECA interconnection and conductive backsheet on back-contact Metal Wrap Through (MWT) Modules. The study will look 
more specifically at the performance and reliability through material testing, accelerated aging and field testing.

An already fiercely-contested sector, H&S training is of critical importance for almost all organisations operating within the offshore industry. We found out more about Survivex, an Aberdeen-based company that has made massive inroads in a few short years, and the facilities it employs to deliver the best possible training.The offshore Oil & Gas industry has spent decades enhancing and refining systems, processes and procedures to make the sector a safer place for those who work within it. Widely recognised as one of the world's most hazardous operating environments, worker safety has been given priority status and as such accidents and incidents are disproportionately low within the sector.The industry has come to recognise the importance of investing in personnel to ensure they possess the core skills required to undertake the roles assigned to them more effectively and therefore with greater efficiency. Comprehensive and specialised training in a variety of disciplines, including working at height, confined space and lifting operations, has been implemented to meet the specific demands of the industry and to comply with government regulation.As a rapidly growing sector, with many parallels to Oil & Gas, the wind industry undoubtedly experiences many of the same challenges as its energy counterpart;

WTG Partners ApS has become one of the forerunners in this non-destructive, inspection-based service for the wind industry, and applies its skills to many of the sector's leading stakeholders. But what's involved, exactly? We asked thecompany's Christian Holmgaard to talk us through the process.WTG Partners use both traditional UT and an advanced form of NDT (Non Destructive Testing) called Phased array scanning, which is different to UT in the sense that it utilises a number of phased UT scan heads in one single probe. And with the equipment we use it means that we can see 3D images of the hidden defects inside the material, and when coupled with an encoder, we have a 3D, true-to-scale file for analysis.We have adopted both PA and UT to work on composites, primarily to use on wind turbine rotor blades where we survey the manufacturing of new and operational rotor blades both in the field and as a factory acceptance test. This has proven to be a successful effort that uncovers hidden delaminations and glue voids that have an impact on the structural integrity of the rotor blades. And this in turn cuts the risk of installing rotor blades with less than

From initial baseline ecological survey to impact assessment and the design and delivery of monitoring and mitigation schemes, Baker Consultants ensures ecological compliance for clients who are under increasing regulatory pressures. We took a look at the company's recent work on the Borkum Riffgrund wind project.The projectWith a capacity of up to 277MW, and able to supply carbon-free power to nearly 285,000 German households' annually, Borkum Riffgrund 1 is one of the largest offshore wind farms consented in German Waters.In 2013 Baker Consultants was awarded the tender by GeoSea, part of DEME Group, for the environmental package of DONG Energy's Borkum Riffgrund 1 wind farm construction. This consisted of monitoring the underwater noise levels and harbour porpoise activity during the installation of the wind farm foundations, as well as assessing the efficiency of the noise mitigation strategy.Baker Consultants' Marine team was involved from the early stages of the project, designing a methods statement for the monitoring campaign during installation to be approved by the German government. The project team then worked closely with the installation company (GeoSea), the piling company (IHC Hydrohammer) and the consent managers at DONG Energy, to ensure that mitigation protocols were followed and to advise on
