WHERE WOULD BE THE WIND FARM BEST PLACED?
Wind power is the conversion of wind energy into a useful form of energy, such as using wind turbines to make electricity or windmills for mechanical power. At the end of 2010, the worldwide installed capacity of wind-powered generators was 197 GW. Wind power now has the capacity to generate 430 TWh annually, which is about 2.5% of worldwide electricity usage. In the context of the actual level of scarce traditional energy sources, meaning fossil fuels such as coal, petroleum and natural gas, which can sustain the global consumption of energy for only a few more decades, the need to invest in renewable sources of energy has become more and more obvious and pertinent. Over the past five years the average annual growth in new installations has been of 27.6 %. Wind power market penetration is expected to reach 3.35 % by 2013 and 8 % by 2018. Several countries have already achieved relatively high levels of wind power penetration, such as 21% of stationary electricity production in Denmark, 18% in Portugal, 16% in Spain, 14% in Ireland and 9% in Germany in 2010. As of 2011, 83 countries around the world are using wind power on a commercial basis.
Romania’s moderate continental climate and its relief are very favourable for the development of wind energy, which in a few years time could replace a good part of the present running-out resources, coal and gas, becoming one of the main sources of energy for our country. But in order to achieve this, a few wind turbines spread around the country, as they are at the moment, are not enough; instead, a large powerful wind farm is necessary, which could really make a difference.
Consequently, the aim of this project is to provide a solution for this identified need by analyzing and answering some practical questions: how powerful should this wind farm be and where it would be best placed around the country .
In order to conduct my analysis I have used secondary data: a database provided by the Romanian Wind Energy Association. (see the Annexe, sheet called “Eolian”) .
2. GENERAL INFORMATION ABOUT WIND POWER AND WIND ENERGY GENERATION Wind power, as an alternative to fossil fuels, is plentiful, renewable, widely distributed, clean, produces no greenhouse gas emissions during operation, and uses little land. In operation, the overall cost per unit of energy produced is similar to the cost for new coal and natural gas installations. The construction of wind farms is not universally welcomed, but any effects on the environment from wind power are generally much less problematic than those of any other power source. The total amount of economically extractable power available from the wind is considerably more than present human power use from all sources. The most comprehensive study as of...
