1Lecture 1 - IntroductionJoachim ClaessonPrepared by Jaime Arias
2AgendaBrief History of Energy UsagePresent Energy Utilisation in Sweden… in the WorldThe Need for Sustainable Energy Utilisation
3Brief History of Energy Usage” Gatherers” - Early HumansProvided by food they could gatherEnergy Usage: 2000 kCal/person and day == Basal Metabolism: Energy intake to keep yourself alive.2000 kCal = 8.2 MJ
4Brief History of Energy Usage”Hunters - Gatherers”(about 1 million years ago)Controlled use of fireDeveloped hunting methods=> Colonisation of less hospitable regionsEnergy Usage: 4000 kCal/person and day4000 kCal = 16.4 MJ
5Brief History of Energy Usage”Settlers”(about 4000 BC in Middle east)Need for more material for building houses and running farmsEnergy Usage: 50 MJ/person and dayThere are people today that live at this level!
6Brief History of Energy Usage”More Developed Societies”(about 1500 AD)More specialised tradesService sectorUse of metals and glass (energy consuming to produce!)Energy Usage: 90 MJ/person and day
7Brief History of Energy Usage”Industrialisation”(1700-1850)Steam enginesFactoriesEnergy Usage: 380 MJ/person and day
8Brief History of Energy Usage”Modern Societies”(Data for Europe, USA, Canada, Australia)Energy Usage: ? MJ/person and day
9Modern SocietiesIn Sweden the energy usage for year 1999 was 615 TWh, whatis the per capita energy use per day in MJ if the population inSweden is 9 million? Hint: 1 Wh = 3600 J.Energy usage per year=615·1012[Wh/year] · 3600 [J/Wh] ==2.214 ·1018[J/year] =2.214·1012[MJ/year]Energy usage per day== 2.214·1012[MJ/year]/365 [days/year] == 6.066·109[MJ/day]Energy usage per capita and day== 6.066·109[MJ/day]/9·106[persons]=674 [MJ/capita/day]
10Sustainable development has influenced the differentsectors of society. Sustainable development is a conceptwhere environmental management, social equity andeconomic growth interact both for the benefit of presentand future generations.Energy influences these three dimensions of sustainabledevelopmentSustainable Development
11Energy is fundamental to increase productivity andindustrial activities, to improve the standard of living ofpeople in the world, especially in developing countries,and to reduce the emission of greenhouse gases.Nevertheless, energy is associated in many aspects withunsustainable development. Global warming and ozonelayer depletion are two issues linked with energyproduction and energy utilization.Sustainable Development
12Buildings have a significant impact on the environment,accounting for one-sixth of the world’s freshwaterwithdrawals, one-quarter of its wood harvest, and two-fifthsof its material and energy flows.
