摘要:Like any investment, efforts to finance energy-efficiency projects benefit from thinking ahead about the pros and cons of different options. For example, what is the best way to pay for the project — through the agency’s General Fund or by working with an energy services company? What are the payback period and return on investment for the different financing approaches? Are financial incentives available that reduce the project’s cost? Is it worth spending more up front for greater energy efficiency to save more money over the long term.
