Argumentative presentation: Estonia does need a nuclear power station Good evening. My name is Margus and I will be talking to you about why does Estonia needs a nuclear power station. My talk consists of 3 parts: the current situation, renewables and how can nuclear power save Estonia from an energy crisis. My talk will last for 2-3 minutes and questions can be asked at the end. Power consumption is increasing exponentially in all civilised countries. Estonia's coal based power generation is becoming obsolete in the near future. The question arises : "Where will the future generations get the energy that they need?". First of all, in the current year, the power consumption reached the highest of all tomes in February
fossiilkütuste peale. Ometi räägivad maailma suurimad naftatootjad, et hiljemalt 2050. aastaks on vaja, et vähemalt ühe kolmandiku maailma energiast kataks taastuvenergia. Kas on see võimalik, teades, et rahvastik pidevalt kasvab ja inimesed nõuavad järjest rohkem? On selge, et peame selle peatamiseks midagi ette võtma. Sellega peaks arvestama kogu ühiskond, et see ei saa enam kauaks jätkuda.

muutmiseks?Millliseid alternatiivseid energialiike oleks võimalik kasutada? Arvan on vaja areneda taastuvate energiavarad et toetada riik elektrieenergiaga . Näiteks kasutada päikeseenergia see on kõige loogiline variant nii riigis nagu Saudi Arabia, sest kasutada nafta ei ole ökonoomselt ja ökoloogoline.

Kas riigil on reserv või defitsiit? Ontario, Canada's most populous province, generates some 9,600 MW annually, over half of that coming from one dozen nuclear reactors. Ontario also has coal, natural gas, and hydro facilities. However, Ontario faces a challenge as it must replace 80% of its generating capacity in the next twenty years—the old stations have time-expired and the nuclear reactors are overstressed. A debate continues over whether to go largely nuclear or go with renewables.

technologies in estonia and baltic sea countries. The hole technological chain from production to flue gas cleaning is brought to reader ´s. Also the energy policy and reguierment for users is shown. Properties of boifuels and peat In the boiler plants of Baltic Sea countries a wide range of various woodbased fuels are burned. To some extent also straw and other biomass based fuels are used. All these fuels are considered as renewables and according to the international agreement the CO2 emitted by the combustion of these fuels is not listed as a greenhouse gas. Wood, in particular the shell of wood cells, consists mainly from cellulose, lignin and hemicellulose. Due to the high carbon and hydrogen content, the lignin has higher calorific value than cellulose and hemicellulose. In smaller quantities the wood contains also tar, resins and phenols that can cause fouling of heat transfer

tegemistes. Hariduspoliitika: Noortel peab roheliste arvates olema juurdepääs stabiilsematele töökohtadele ja parem võimalus saada haridust, koolitust ja leida eluase. Välispoliitika: Rohelised soovivad, et Euroopa tähtsustaks energiasäästu senisest hoopis enam. Taastuvad energiaallikad peavad olema Euroopa energiapoliitika keskmes 21. sajandil ning Rohelised kutsuvad selleks üles looma Euroopa Taastuvenergia Ühendust (ERENE, European Renewables Community), mis toetaks pikaajalist eesmärki saada 100% energiast taastuvallikatest. Euroopa põllumajandus-, kalandus- ja toidupoliitikad peaks aitama luua mõlemapoolset vastutust põllumeeste, kalurite, tarbijate ja ametivõimude vahel.
3. Conclusion............................................................................................................ ....18 4. Sources............................................................................................................... .......19 Renewable energy Renewable energy is energy generated from natural resources--such as , wind, rain, tides and geothermal heat--which are renewable (naturally replenished). In 2006, about 18% of global final energy consumption came from renewables, with 13% coming from traditional biomass, such as wood-burning. Hydroelectricity was the next largest renewable source, providing 3% (15% of global electricity generation),followed by solar hot water/heating, which contributed 1.3%. Modern technologies, such as geothermal energy, wind power, solar power, and ocean energy together provided some 0.8% of final energy consumption. While there are many large-scale renewable energy projects and production, renewable technologies

Wind is a renewable energy source that does not pollute so some people see it as a good alternative to fossil fuels. To learn more about wind, visit the wind section of the site. 37 Picture 10.3. Wind turbine HYDROPOWER Of the renewable energy sources that generate electricity, hydropower is the most often used. It accounted for 6 percent of total U.S. electricity generation and 71 percent of generation from renewables in 2007. It is one of the oldest sources of energy and was used thousands of years ago to turn a paddle wheel for purposes such as grinding grain. Our nation's first industrial use of hydropower to generate electricity occurred in 1880, when 16 brush-arc lamps were powered using a water turbine at the Wolverine Chair Factory in Grand Rapids, Michigan. The first U.S. hydroelectric power plant opened on the Fox River near Appleton, Wisconsin, on September 30, 1882
