Renewables Portfolio Standards: What Are We Learning?

Renewables Portfolio Standards: 13 states have enacted RPS policies, which obligate suppliers to deliver a certain amount of renewable energy. Renewable Energy Funds: 15 states have set-aside funds to financially support renewable energy sources. Green Power Markets: Utility green pricing programs, competitive green power markets, and REC marketers have all emerged. Tax Incentives: Federal production tax credit for wind, investment tax credit for solar and geothermal, and accelerated depreciation, as well as state tax incentives, all help spur development. Economics: Some forms of renewable energy, especially with tax incentives, can compete on cost alone (e.g., wind at ~2-4 cents/kWh).
