Money, money, money -- or lack of it. It’s the main thing that state and local governments continually say interferes with their ability to invest in green energy projects. The U.S. Environmental Protection Agency is making it a little easier, though, with the creation of an online quiz that tells officials their best option for paying for a particular clean energy or energy efficiency project. With nine clicks of a mouse, the Financing Program Decision Tool shows users their best financing options among loans, payment plans and programs like Property Assessed Clean Energy and the Department of Housing and Urban Development’s PowerSaver. The tool details what each option pays for and how, how difficult it is to implement, the government’s role, repayment plans and more.
