A National Green Bank would provide lower interest rates for renewable energy projects with relatively new business models. By lowering interest rates for capital projects, a National Green Bank will decrease the price of renewable energy. Capitalized with an initial $10 billion, the Bank could leverage $100 billion in private capital (a 10-1 ratio). The bank would operate at no net cost to the taxpayer, as it recoups loans from clean energy projects with guaranteed financial returns. As borrowing costs decline, so too will carbon emissions as the bank increases rates of renewable energy installations. A National Green Bank is capable of reducing greenhouse gas emissions 1.7-2.6% by 2020.
