The sea is without doubt one of the biggest backers of renewable energy future and the Canary Islands have great potential for installing offshore wind farms (away from the coast). Data are the first Marine Wind Atlas de Canarias, developed by scientists at the University of Las Palmas de Gran Canaria and University of Vigo in collaboration with the Wind Zone Canarias SA, which is an important tool for energy entrepreneurs who want to bet on insurance.
The map shows a very relevant information about the sites with higher speeds, most notably the south-west of Gran Canaria, the area between the east of Tenerife and the west-west of Gran Canaria (in the hall called international waters), southeast of the island of El Hierro in the west of La Palma and in the area between the east and west of La Palma on the island of La Gomera.
In such locations can be reached average values of wind speed in the range of eight to ten meters per second. Fuerteventura and Lanzarote have very similar average speeds defined in the environment in the range of four to six meters per second.
The atlas, developed by the researcher of the University Institute of Intelligent Systems and Numerical Applications in Engineering (Siani) from ULPGC, Jose Fernando Medina, in collaboration with researchers at the University of Vigo, Andrew Elias Feijoo, and industrial engineering ULPGC company and member of the Wind Zone Canary SA, Aday C. Mederos Martín-evaluate the existing wind potential in the sea canary.
Covers an area of 212,760 square kilometers, which covers El Hierro, La Palma, La Gomera, Tenerife, Gran Canaria, Fuerteventura and Lanzarote, as well as six smaller islands (Alegranza, Graciosa, Montaña Clara, Lobos, Roque del Este and Roque West) and a small part of the North African coast belongs to Morocco.
“Analyzing the data we can conclude that the estimate widely operating hours is around the 4,500 hours a year,” say authors of the atlas. This is the first initiative to evaluate the wind resource of the whole sea in the Canaries, where previously only been made an extrapolation of the wind measurements made on land to a few meters from the sea coast. These results now provide the basis for planning and future development of offshore wind farms.
