Check out this article that talks about the HRAI report on GSHPs.
The study was done by Dunsky Energy + Climate Advisors.
“For many years, experts in the field have known that ground-source heat pumps (GSHPs) offer considerable energy cost savings to Canadians while reducing carbon emissions and contributing to Canada’s fight against climate change. This report clearly shows that, in addition to these savings, the technology has unique attributes that could deliver many billions of dollars in savings to the electricity grid,” said Sandy MacLeod, HRAI president and CEO.
The report found that a reasonably ambitious adoption rate of ground-source heat pumps over the next few decades could save Canadians between $49 and $148 billion in avoided electricity system development investment costs – investments that would otherwise be required as part of the country’s GHG emissions reduction plans.
