A North Bay-based company that builds energy efficient homes has caught the attention of energy minister Glenn Thibeault. Super Shell uses innovative insulation systems that can cut energy costs by as much as 50 percent.  Thibeault visited the company in North Bay on Wednesday and says the kind of innovations Super Shell uses is only the beginning.  Thibeault says it’s the government’s intention to export this innovative technology nation-wide and internationally which will also help create jobs.
