The kinetic energy of wind can be used to set electricity-producing turbines in motion. People have been using wind power for over 5 500 years. Their initial application was in sailing boats and ships. Wind mills were first used for the purposes of plant watering, water pumping and grain grinding in 7th c. A. D. on the territory of today’s Afganistan, Iran and Pakistan. Where would you set up wind power generators?I’d set them up in the fields and help farmers pump up water for their wheat or whatever crops they have sown. We will thus help them lower their electricity bills and they will be able to sow more crops. Wind and its power have several advantages – its available in large amounts, it’s cheap, it’s a practically inexhaustible energy source and it doesn’t cause pollution. The EU provides funding for projects aiming to set up wind power generators. The co-funding in Bulgaria is done under Measure “Support For Establishment and Development of Micro Enterprises” within the Rural Development Programme. Mariya Nedelcheva, MEP: In terms of the Second Pillar of the Rural Development Programme, it’s necessary that farmers be stimulated to protect the environment, including financially, and not feel it as a burden. The fact is environmental protection takes a lot of resources and efforts. I believe these are the primary issues we must address in order to support the Bulgarian cause. We might go into details later and negotiate direct payments and the criteria related to them. It’s necessary that all EU member states define a common set of objective criteria reflecting the specific realities in the different countries and ultimately serving as a guarantee of fairness. As regards the Second Pillar, it was a very encouraging sign to me when the European Commissioner on Agriculture declared that one of the main goals would be the achievement of a territorial balance and a much more intensive stimulation of small agricultural producers. It has been one of the main disadvantages of the Common Agricultural Policy so far. Wind power generators convert the kinetic energy of wind into electricity. There are two types of wind power generators – with a horizontal and with a vertical axis of rotationThey consist of a wind generator, a controller and an inverter. Each big turbine could produce as much electricity as it is necessary for the functioning of home electric appliances for a month. Hybrid solar-wind energy systems combine the advantages of wind generators and photovoltaics. In summer, when wind is lighter, the photovoltaic is the dominant energy source and in winter, when there’s less sunshine, it’s the other way round. The dome on the top might be intended for solar power. Bulgaria has some of the best conditions for the development of wind energetics in Eastern Europe. The largest wind parks in the country are concentrated in North-East Bulgaria, where wind speeds are higher and the existing electricity network is of a low capacity due to the traditionally agrarian character of the region. Hello! Didn’t they show you earlier where these wind generators are situated?The first wind turbine connected to the electricity distribution network works in Aheloi. It’s part of a project for electricity provision for an animal farm. In Bulgaria there are also good prospects for the construction of wind farms along the Black Sea coast and in areas situated over 1000 m above sea level. Ecologists have raised concerns over the fact that wind turbines are a threat to migrating birds which also happen to be using the winds along their flights over thousands of kilometers. Bulgarian zoologists and ornithologists claim that wind energy turbines place migrating birds in direct risk. You’ve been eating pure food, you’ve been drinking clean water. Nature has been close at hand – open the door and there’s a nice landscape, everything’s fine. And now they are going to build these machines and spoil everything, pollute nature, endanger the birds. Nevertheless, according to producers and investors there have been no cases of birds killed by wind turbines yet. It’s not right. Nature is very important. We’re one with it, we live in it. What are we going to do without it?Apart from posing a threat to birds, wind generators are very noisy, according to people living nearby.
