Choose the option opposite in meaning to the underlined word(s).
There is no point dissipating energy on a useless argument?
Answer Details
The opposite of "dissipating" is "conserving". When we say "dissipating energy", it means wasting or using up energy in an inefficient or useless way. Therefore, "conserving energy" means to save or preserve energy instead of wasting it. So, the sentence "There is no point dissipating energy on a useless argument" means that it's not worth wasting your energy on an argument that won't lead to anything productive. The opposite of that would be "There is a point in conserving energy for more important matters."
