The Energy Return on Investment (EROI) is a measure of the amount of usable energy that is produced from a certain amount of input energy. It is calculated by dividing the energy produced by the energy consumed.

In this case, the EROI of the coal power plant is given as 15. This means that for every unit of energy consumed, the power plant produces 15 units of energy.

The power plant generates an average of 3000 GWh of useful electricity per year. To find out how much input energy the power plant consumes annually, we need to divide the energy produced by the EROI.

So, the total input energy consumed by the power plant annually is 3000 GWh / 15 = 200 GWh.

However, the options are given in TJ and GJ. To convert from GWh to TJ, we need to know that 1 GWh is equal to 3.6 TJ.

So, 200 GWh * 3.6 = 720 TJ.

Therefore, the coal power plant consumes 720 TJ of input energy annually.
