The context of the following conversation is Casey had installed solar panels. He had to properly maintain the power structure.:
Casey says I've installed solar panels on my roof to reduce my carbon foot print. I feel pretty good about it..
The friend responds That's a good plan. Energy costs and global warming are becoming more of a problem everyday..
Casey responds I've been taking care of the power structure, and the cost is not too bad. It just takes some work to maintain..
The friend responds Just like anything worthwhile. You have to take care of it if you want it to work well and last..
Casey responds That's very true. The panels seem pretty sturdy, but the cables require insulation that has to be replaced annually..
The friend responds That's not such a big deal. It sounds cost efficient..
