Howard punches enough of a hole into it that he can reach his arm in. He feels around blindly in there. "Nobody keeps their electrical wiring on the outside of their walls. I just need to find where it is. Mostly insulation in here, though."

Honestly, Howard's fine with totally getting rid of nature (nature is evil! It'll kill you!), but he's not about to tell Zouichi that. Given how Zou feels about animals and gardening, he's pretty sure it won't win him any points. "Conserving less? What about resources?"
