  1. Energy and CO2 - measuring and calculating - Wolfenbüttel, 07.02.2017 Think Smart – Act Green

  2. Introduction – energy quiz Measuring power consumption on our devices Calculating the CO2 emission Content of this workshop Think Smart – Act Green

  3. Energy quiz Think Smart – Act Green Electric energy is measured in the physical unit: kWh – that means “Kilowatt hours“. Question 1 How much kWh do you need per year for watching TV (4 hours per day)? A) ≈5 kWh B) ≈30 kWh C) ≈220kWh

  4. Energy quiz Think Smart – Act Green All factories and all families need energy. Question 2 Sort our five project countries in order of energy usage per person (start with the country using the most). • Sweden, Germany, Italy, Greece, Portugal • Germany, Sweden, Italy, Portugal, Greece • Italy, Germany, Sweden, Greece, Portugal

  5. Energy quiz Think Smart – Act Green 16% of all people worldwide live in Africa. Question 3 What is the rate of the energy used worldwide on the African continent? • ≈ 3% B) ≈ 11%C) ≈ 14%

  6. Energy quiz Think Smart – Act Green There are a lot of possibilities for producing renewable energy. Question 4 What is the most common way in Europe to produce renewable energy? • Solar energy B) Wind energy C) Biogas energy

  7. Energy quiz Think Smart – Act Green One aim of the EU for the year 2020 is, that in each of the 28 member states 20% of the needed energy should be energy from renewable sources. Question 5 How many European countries do already reach this goal now? • 2 countries B) 9 countries C) 17 countries

  8. Part 2: Measuring power consumption on our devices Think Smart – Act Green 2 – 3 students at every device, up to 10 minutes time per device, then change device

  9. Part 3: Calculate the CO2 emission Think Smart – Act Green What information do we need for this calculation? What kind of natural resources are used for the production of electric energy?

  10. Think Smart – Act Green Germany 535g CO2 / kWh

  11. Energy quiz Think Smart – Act Green Fossil resources like coal and natural gas are used in power plants to produce electric energy. Question 6 Brown coal has the worst 2 emissions. Compared with natural gas the CO2 emissions of brown coal is • two times higher B) three times higher • C) four times higher

  12. Think Smart – Act Green

  13. Energy quiz Think Smart – Act Green To stop global warming the world agreed on the 2°C aim – the increase of the temperature should be less than 2°C compared to pre-industrial times. Question 7 Without reducing the CO2-emissions, we will go above this level • in 15 years B) in 19 years C) in 23 years

  14. …. and to make it more practical….. Think Smart – Act Green Everybody can eat 100.000 waffles till this CO2-budget is spent. …. or eat 90.000 waffles and fly 3500km ….
