A river has been used to irrigate farm land. A 3000 megawatt, coal-fired electric generating plant which would require about 40,000 acre-feet of water per year from the river. Operating the generating plant would mean less water for agriculture.
The first part of the question is: which is more efficient use of the water from the river growing food or generating electricity. The part that is giving me trouble is comparing the value of food with the value of electricity.
<br>Of course the question does not provide nearly enough information to provide an answer. However, we can analyze the comparison to help find an answer if we have all the details.
<br>The question boils down to this. How much less food can be grown with the removal of 40,000 acre feet of water? Maybe there is no loss of food and only benefit of more electricity. Assuming there is a loss, how much food ...
