Elektros Erdvës Nr. 3 (17) 2007 46 summary FoR tHE dARK to BE AS SHoRt as possiBle IN lItHUANIA 6 Modern life is unimaginable without electricity. The electricity considerably determines the standards of living, creates the conditions for further progress. Unfortunately, until now it is impossible to avoid the disturbances of the electricity supply, sometimes even large ones. It is until now impossible to ensure the continuous supply of the electricity to all consumers, but this goal is being striven for. In the article the most notable accidents of the interruption of the electricity supply and their consequences are analyzed. The are discussed the peculiarities of Lithuanian energy supply and ways of avoiding possible accidents. lIFE-cIRclE to tHE europe, that Fits AlSo FoR tHE RESt part oF the World 24 It is more and more often spoken about the disastrous climate change and, as it is supposed, the increase of carbon dioxide in the atmosphere that speeds up this change. One the most prominent scientists, an astrophysicist living in England Stephen Hawking, wishing to attract the attention of the world‘s powerful ones, has evaluated the climate change as much more dangerous than the international terrorism. The European Electric Energy Industry Union EURELECTRIC, concerned about the prospects of the EU energetics, has begun in 2005 to create the European energetics strategy, - it has performed the study „ The role of electric energetics - the new outlook to energetics that is safe, competitive, and diminishing the emissions of CO2“. This study is analyzed in detail in the article. electric spaces the protection oF Wind poWer stations FRoM lIgHtNINg ANd excess voltages 30 It is begun actively to build and exploit the power stations, producing the electricity from renewable sources (wind, sun and geothermic energy, water and biomass) during the last years in the Europe, as well as in Lithuania. In Lithuania the most favourable conditions are for the development of the systems that use wind and water energy. After the entering into the EU, Lithuania took an obligation to perform the requirements of the directive 2001/77/EC, according to that, 7 per cent of the electric energy, generated in Lithuania must be produced from alternative energy sources until 2010. It is planned that, until 2010, the capacity of wind power stations would reach almost 200 MW. The capacity of the wind power stations that are produced and built now is about 1 MW, and the capacity of their complexes (parks) is larger than 10 MW. In the article there are presented the technical decisions how to protect the wind power stations from lightning and excess voltages.

Dažniausiai Jūs naudojate T8 lempą su elektromagnetiniu balastu: Gadinate sveikatą – nes šviestuvas sunkiai užsidega, lempa zyzia ir mirga, sunku skirti spalvas. Švaistote pinigus – 2x36 W lempoms + 2x18 W balastams = 108 W. Jūs galite pereiti prie T5 technologijos: Išmesti seną T8 ir starterį, į tą patį korpusą įdėti T5 su reflektoriumi. Balastą galima išmesti arba palikti, jis energijos nebenaudoja. Rezultatas: 2x28 W lempoms + 2x 0,5 W balastams = 57 W arba energijos taupymas 48 proc. Papildomai – 10 proc. padidėjusi apšvieta, geresnis spalvų skyrimas, jokio mirgėjimo. Dažniausiai Jūs naudojate 400 W metalų halogenų lempą su elektromagnetiniu balastu. Gadinate sveikatą – nes mirga ir greitai netenka savybių, sunku skirti spalvas. Negalite kada norite įjungti/išjungti – reikia laukti nustatytą laiką. Švaistote pinigus – 400 W lempai + 72 W balastui = 472 W. Jūs galite pereiti prie T5 technologijos: Naudoti 4 T5 HO lempas šviestuve su aukštos kokybės reflektoriumi. Rezultatas: 4x54 W lempoms + 4x1 W balastams = 220 W arba energijos taupymas 53 proc. Papildomai – stabili apšvieta, geresnis spalvų skyrimas, jokio mirgėjimo, laisvė įjungti/išjungti.
