Opgave 2
a)
b) De stijging is (355-311) = 44 ppm in (2020-1957) = 63 jaar. Dus de rico = 44/63 = 0,698 ppm
per jaar.
c) In oktober 1960 was de CO2-hoeveelheid 314 ppm. De procentuele toename bedroeg dan
100% * 0,698/314 = 0,22 % (verdubbelingstijd = 315 jaar)
d) De stijging is (418-310) = 108 ppm in (2020-1978) = 42 jaar. Dus de rico = 108/42 = 2,57 ppm
per jaar. In oktober 2018 was de CO2-hoeveelheid 415 ppm. De procentuele toename
bedroeg dan 100% * 2,57/415 = 0,62 % (verdubbelingstijd = 112 jaar.
e) Er is dus in de afgelopen 63 jaar sprake geweest van een meer dan exponentiele groei.
Hoofdstuk 2
Opgave 3 Energiegebruik
a) Elektra: 10 kWh * 3,6 MJ per kWh =36 MJ per dag. Dus 36 x 365 = 13140 MJ = 13 GJ/jaar.
Gas: 1600 m3/jaar gas * 32 MJ/m3 = 51200 = 51 GJ/jaar
Auto: 19000/20 = 950 liter ; 950 liter * 32 MJ/liter = 30400 MJ = 30 GJ
Opgeteld is dat 94,7 GJ en per persoon is dat 32 GJ per jaar.
b) Elektra: 100% * 13,14/94,7 = 14%
Gas: 100% * 51,20/94,7 = 54%
Auto: 100% * 30,40/94,7 = 32 %
c) 17 mln *32 GJ = 544 GJ.
