Dear tutor,
The environmental goal is to reduce CO2 emissions by 20% in the next 5 years. However, based on the answer, the reduction is based on CO2 per max MW.
By adding another nuclear station, the total CO2 emissions would actually increase, not decrease. The CO2 per max MW will decrease but is it relevant to the goal? Is there something that I am missing?
In plan A, total generating capacity stays the same (+1200 – 300 – 600 – 300), but CO2 emissions go from 26.51mt to 22..43mt.
Both total CO2 and CO2/MW go down.
Hi,
I’m just going through question 3a Dec 2014.
Apologies if this is a daft question:
How is the total CO2 emissions calculated?
the model also says “The total power output of Maxwell is maintained at 10,200 MW”. how has it reached that number?
Thank you,
For plan 1A
One small coal plant is lost, leaving 3. 3.15 x 3/4 = 2.36
One large on is lost, leaving 3. 12.61 x 3/4 = 9.46etc
Power generation = sum of the number of each type of plant times maximum generating power:
300 x 4 + 600 x 4 + 300 x 8 + 900 x 2 + 1,200 x 2 = 10,200
It’s mentioned that a nuclear plant takes 5 years to built and the goal of the CO2 reductions lie in the same timeline.
CO2 reductions wouldn’t have taken place at the time the nuclear plant would have existed.
Don’t you think there is some error in the question?
