We achieved a 3x return on equity. Where else can we get that in the current market?

Carbon Lighthouse predicted solid return on cost and environmental goals, so I did extensive due diligence on the technology and company, and I’m excited to say they performed well and returns exceeded what was promised. After capitalizing the perpetual savings, we achieved a 3x return on equity. Where else can we get that in the current market? We’ve used them everywhere we can.
