Assessing the wind resource of a project site
Assessing the wind resource of a project site breaks down into two stages. First, wind measures are taken on the site of the future wind farm (read the “How do we measure the wind on a site?” article); then, these measures are matched with those gathered by several sources of long-term wind data in the region surrounding the site of the project.
The Rio summit, an opportunity for renewable energy?
At the end of June 2012, Rio will be hosting the next Earth Summit, the world’s ten-yearly meeting on sustainable development. In December 2011, Durban, South Africa, hosted the annual conference of the countries that have signed the UN convention on climate change agreed at the 1992 Earth Summit. Pierre Radanne, Chairman of Futur Facteur 4 and Emmanuel Guérin, Program Director at IDDRI (Institute for Sustainable Development and International Relations) take a look back at this event and tell us whether renewable energy can emerge as a winner.
How do we measure the wind on a site?
The wind measurement campaign is a critical step in the development of a wind energy project. Accuracy and consistency of measurements are instrumental in the design and optimization of the lay-out as well as in the feasibility analysis and eventually in the financing of a project. Several measuring solutions are implemented by wind resource analysts when it comes to collecting and analyzing wind data. Some of the most mature and widespread measuring techniques are presented in this article.
