The Civil engineering discipline would have little ability to deal with this specific topic any more than your average person. Although your average person can research this with no engineering and understand pretty easily the issues with wind compared to hydroelectric, relating to reliability, and peak demand.
If you're looking for an engineer who would better understand this a mechanical or aerospace is probably going to be more suited than the other engineering disciplines. However, this really isn't an engineering issue with the exception of understanding how ridiculous the concept of backing up the grid by battery is. This is more an issue of understanding how the power grid works and how consumer demand works. Most people don't get what peak demand is or what type of energy generation is best suited to meet baseline demand.
One thing a lot of the enviromentalists do not get or want to accept is any solution we implement will have some negative consequences. There is some negative consequence to anything we do. We need to accept that and choose the least negative outcome.
