Resumen/Abstract The competitiveness of renewable power generation technologies continued improving in 2013 and 2014, reaching historic levels. Biomass for power, hydropower, geothermal and onshore wind can all
provide electricity competitively against fossil fuel-fired power generation. Solar photovoltaic (PV) power has also become increasingly competitive, with its levelised cost of electricity (LCOE) at utility scale falling by half in four years. Renewable Power Generation Costs in 2014 aims to reduce uncertainty about the true costs of renewable power generation technologies, so that governments can be more ambitious and efficient in their policy support for renewables. As this comprehensive report from the International Renewable Energy Agency (IRENA) underlines, perceptions that such technologies are expensive or uncompetitive are outdated, at best.

Resumen/Abstract The recent past was rather difficult for mining companies as commodity prices fell considerably; in 2013 for instance, gold fell by 40%, iron ore by 8% and nickel by 27.6%. The falling commodity
prices had a direct impact on the revenues and profits of mining companies. The market capitalization of the largest 40 global mining companies declined in 2013 with net profits falling 72% to $20 billion, an extreme descent. The market capitalization of the top 40 mining companies fell by $280 billion, which translates into 23%, to $958 billion at the end of 2013. Energy cost are becoming increasingly important in mining operations. First, the majority of easily accessible sites have already been exploited, which makes it necessary to dig deeper; therefore, more energy per unit of raw material is needed. Second, the energy prices have increased considerably during the last few years. This trend is expected to continue and accelerate in the following years. This study examines whether a renewable energy commitment for mines could have a direct impact on the stock value of mining companies. The study looks at direct factors such as energy prices and indirect factors such as environmental image and perceived management quality.

Resumen/Abstract Coupled dynamic analysis has an important role in the design of offshore wind turbines because the systems are subject to complex operating conditions from the combined action of waves and wind. The
aero-hydro-servo-elastic tool FAST v8 is framed in a novel modularization scheme that facilitates such analysis. Here, we present the verification of new capabilities of FAST v8 to model fixed-bottom offshore wind turbines. We analyze a series of load cases with both wind and wave loads and compare the results against those from the previous international code comparison projects-the International Energy Agency (IEA) Wind Task 23 Subtask 2 Offshore Code Comparison Collaboration (OC3) and the IEA Wind Task 30 OC3 Continued (OC4) projects. The verification is performed using the NREL 5-MW reference turbine supported by monopile, tripod, and jacket substructures. The substructure structural-dynamics models are built within the new SubDyn module of FAST v8, which uses a linear finite-element beam model with Craig-Bampton dynamic system reduction. This allows the modal properties of the substructure to be synthesized and coupled to hydrodynamic loads and tower dynamics. The hydrodynamic loads are calculated using a new strip theory approach for multimember substructures in the updated HydroDyn module of FAST v8. These modules are linked to the rest of FAST through the new coupling scheme involving mapping between module-independent spatial discretizations and a numerically rigorous implicit solver. The results show that the new structural dynamics, hydrodynamics, and coupled solutions compare well to the results from the previous code comparison projects.

Resumen/Abstract Este trabajo tiene como principales objetivos analizar las complementariedades de los recursos eólico, solar e hidráulico en su aplicación a la generación de energía eléctrica. Dada la
variabilidad inherente de los recursos mencionados, se cuantificó el valor que tendrían proyectos que colaboren su filtrado. Un ejemplo de estos proyectos serían las aplicaciones de Smart Grid para la gestión de la demanda.

Resumen/Abstract The Wind Trends Bulletin is a free report that evaluates deviations in global wind conditions from the historical norm on a quarterly basis. In 2013, global winds were generally within 3% of the
long-term average (1988 – 2012). Winds trended slightly below normal across the western United States, central Canada, central Europe, Siberia, the African Sahel, the Himalaya and Hindu Kush regions of Asia, and western Australia. Winds were slightly above normal across Alaska, southern Europe, northern Africa, eastern China, and southern India. [Excerpt]

Resumen/Abstract This report presents a comprehensive overview of the opportunities for value creation from the deployment of large-scale solar and wind energy technologies. It contributes to bridging the existing
knowledge gap on the topic and gives policy makers and other stakeholders evidence on economic value creation from the accelerated deployment. The report analyses various policy instruments that stimulate value creation and draws on the experience of developed and emerging countries to provide recommendations on how value creation can be maximised. Guidance is provided on the selection of the appropriate tools to measure the socio-economic impact.

Resumen/Abstract This How2Guide for Wind Energy (Wind H2G) is designed to provide interested stakeholders from both government and industry with the necessary tools to plan and implement a roadmap for wind energy
technology at the national or regional level. This guide is a wind-specific supplement to the IEA generic roadmap methodology manual, Energy Technology Roadmaps: A Guide to Development and Implementation (hereinafter the IEA Roadmap Guide), which was released in 2010 and updated in 2014. The Wind H2G explores key elements of this roadmap process with particular regard to their relevance in developing a roadmap for wind energy technology. This publication is focused on utility-scale wind energy installations (i.e. of multiple megawatts), rather than on smaller plants for individual homes or localised communities. It is likely to be of particular interest to those seeking to grow wind energy markets, both onshore and offshore, whether in countries with limited installed capacity for wind energy, or those with experienced markets seeking to accelerate growth. Recognising that it would be impractical to attempt to cover every aspect of wind energy technology in every national case, recommendations are illustrated throughout the guide with case studies for the reader to consider.

Resumen/Abstract This knowledge note singles out auctions as an important mechanism that has been implemented in a growing number of countries in recent decades. It features a case study of auctions designed to
promote the generation of electricity from renewable sources in Brazil. The Brazilian experience with wind energy auctions illustrates that even carefully designed policies often must be reconsidered in the light of a complex and changing environment. Many considerations need to be taken into account to ensure competitive prices while also delivering the required renewable energy supply. This case study is interesting, because Brazil's initial success with developing wind capacity had unforeseen consequences. Challenges introduced in the first stage of wind power development had to be solved in the second. The chief challenges were (i) the Brazilian system had to be able to balance supply and demand more accurately; (ii) investors were overoptimistic about the amount of electricity able to be generated; and (iii) the government's arrangements for coordinating the planning of generation and transmission left too little room for error. The benefits offered to the auctioned plants were reduced, as was government involvement in planning and coordinating transmission expansion. The key lesson from this case study is that existing policies should be challenged and revised in response to a changing environment.
