1. THE TRAVEL OF ENERGY THROUGH TIME Elina Aunbaum Kristi Uibo Kristi Veskemaa Jelena Jerastova

3. Energy use few decades ago Oil shale energy Oil shale energy  Oil shale is sedimentary rock, brought 400- 500 million years ago  is used for generating electricity or producing synthetical oil  Quarried in mines  As long as oil shale is found in Estonia, it is used for generating energy

5. Generating energy from burning waste  The calorific value of waste is compared with the calorific value of oil shale  It helps to reduce dumping waste  Effective opportunity for generating energy and heat together

7. Nuclear power  Uses nuclear fission energy  Ascribed as an economical and perspective energy  Building power stations is very expensive  May cause big environmental problems  Dumping radioactive waste is a big problem  Estonia wants to participate in Lithuanian project (new nuclear power station)  Year 2023- to build power station - output 60MW

9. Alternative energy Alternative energy  Hydroenergy  Wind energy  Solar energy  Biomass energy Hydrogen energy Hydrogen energy  Safe and gainful  Research in process

10. Role of energy in everyday life People use in everyday life People use in everyday life  Heat energy (electical, oil, stove, gas, coal, peat )  Electricity  Natural energy (petroleum, oil shale, wind energy, solar energy)  Chemical energy (batteries)

11. The role of energy in future  Need of energy enlarges three times  Environmental problems insist of changing energy  Main source of energy – nuclear power  Using natural resources- coal, oil shale, peat e.t.c.

12.  Bigger accent to recovering energy  Building windparks, hydroelectric plants, solarpanels  Estonia has enough recovering energy  Do not depend on oil shale energy  Combined energy- alternative energy + natural resources  More and more use recovering energy

13. Use of energy in future  Oil shale energy  Generating energy from burning waste  Nuclear power  Biomass energy  Alternative energy  Hydrogen energy

14. Alternative sources of energy  Solar energy  Wind energy  Biomass energy  Hydroenergy

15. Biomass energy  Energy produced from wood, brushwood, canebrake e.t.c.  Sufficient resources ( half of territory is woodland)  Time of recovering is quite short

16. Hydroenergy  Quite cheap, environmentally friendly  In Estonia no big rivers

17. Wind energy  Quite big resources  Environmentally friendly  Dependance from nature, weather

18. Solar energy  Environmentally friendly  Can not be used in Estonia in winter
