In the Canary Islands it is possible to take advantage of the strength of the trade winds, which blow throughout the year and especially within the summer months. The work will be based on real data taken from the Agüimes (Gran Canaria Island) power station’s control centre.

The Canary Islands are one of the best places in Spain in wind resource, but with a limited land area 7529 km2, a high rate of population (2,103.992 people in January 2009), a high degree of protected land 42.2% of the territory, very deep waters, and a huge dependence on foreign petroleum for 99% of energy consumed. We have to look for urban wind energy as an opportunity to extract energy without occupying valuable and scarce land, using own resource and diversifying the energy basket. We will study different existing buildings designs and will make our own proposals in order to assess, for which we will use specific software.

The future of wind energy development in Europe and worldwide is undoubtedly the offshore wind farm. Spain is the second European country in installed wind power, with significant own technology, now Spain is preparing to begin the development of offshore technology with the release of specific legislation and an environmental analysis of the entire national coastline. At present there is no offshore farm in Spain, but in 2030 the MITyC wait that the power of wind farms will reach to 40 GW on land and 4 GW offshore. The Canaries are one of the best places in Spain in terms of value of the resource, but with a limited land area 7529 km2, a high rate of population (2,070,465 people in January 2008), a high degree of protected land 42.2% of the territory, and a huge dependence on foreign petroleum for 99% of energy consumed. You have to look to the offshore wind as an opportunity to extract energy without occupying valuable and scarce land, using own resource and diversifying the energy basket. Discusses the possibility to use this technology in each of the seven islands, establishing a procedure for identifying possible places and how the national rules affect us.

Around 1,100 million people they do not have access to an improved water provision, and more than 2,600 million people they lack access to improved services of cleaning. The water shortage affects to approximately between 1,000 and 2,000 million people anywhere in the world. From 1960, the difference between water use and accessible provision have increased in a 20% per decade. The desert ground affects means of subsistence of million people, including a great amount of the poor men of dry earth.[1] FAO's recent report World agriculture: towards 2015/30 projects that global food production will need to increase by 60% to close nutrition gaps, cope with the population growth and accommodate changes in diets over the next three decades. Water withdrawals for agriculture are expected increase by some 14% in that period, representing an annual growth rate of 0.6%, down from 1.9% in the period 1963-1999. Much of the increase will take place on arable irrigated land, forecast to expand globally from some 2 million sq. km to 2.42 million sq. km. In a group of 93 developing countries, water use efficiency in irrigation-i.e. the ratio between water consumption by crops and the total amount of water withdrawn-is expected to grow from an average 38% to 42%. The water needs of humans and animals are relatively small-the average human drinks about four litres a day. But producing the same person's daily food can take up to 5,000 litres of water.
