7.A) What is a Solar Thermal Collector?
A. Somebody who collects Pokémon energy cards? :-)
B. A unit that produces heat from the sun X
C. A unit that produces electricity from the sun

7.B) What is a Solar PV Cell ?
D. A sunny cell in a Buddhist Monastery :-)
E. A unit that produces heat from the sun
F. A unit that produces electricity from the sun X

8.) Which angle is optimal for a solar collector to collect most solar energy?
A. Usually as horizontal as possible
B. Usually the same angle as the latitude of the site (e.g. 52 degree in Belgium) X
C. Usually 70-90 degree from horizontal

9.) How many m2 solar thermal collectors are installed in the EU?

10.) How far should a house be from a wind mill (1.3MW) and from a motorway (50.000 cars/day 120 km/hour) to keep the noise at a reasonable level (45 dB) in front of the house?
A. 500 m from both
B. 600 m from windmill and 300 m from the motorway
C. 300 m from windmill and 1600m from the motorway X ( A motorway is more noisy than a wind mill )

11.) What can we do with the CO2 from a solar collector or a wind turbine?
A. The CO2 can be stored in an underground storage
B. Solar and wind energy use do not produce CO2 :-)
C. The CO2 can be evaporated

12.) Could 100% of the energy supply be covered by renewable energy in 2050?
A. It will be impossible before 2100
B. It is achievable if there is political will X ( See INFORSE's Vision 2050 ! )
C. Only if the population remains below the present number.
