According to Professor Nilsen of the NHH Norwegian School of Economics, ‘the higher the temperature, the lower the power plant’s efficiency – prices therefore rise in line with the temperature’ – see: https://www.nhh.no/en/nhh-bulletin/article-archive/older-articles/2015/april/powerplants-and-climate/
If I visualise the entry and exit to a power station as similar to a Motorway junction, the speed at which heat molecules move forward depends, like that of cars, on the volume of traffic in front of them.
If the road leading to the motorway junction is reasonably empty, the cars (i.e. heat-molecules) can approach the entrance reasonably fast – if it is full, they have to approach more slowly. Similarly, if the motorway is also blocked with slow-moving traffic, the cars (i.e. heat-molecules) entering it are forced to move slowly.
As the speed of the heat-molecules is what causes the rotation of the turbine which creates the electricity, (and the faster the turbine rotates, the more electricity is created) it can be imagined that the turbine works most efficiently when the air ‘upstream’ and ‘downstream’ from it is relatively empty of heat-molecules – i.e. cold.
Is this correct? Please can you tell me how to find the relevant data?
