Green Options

U.S. Representatives Jay Inslee (D-WA), Bill Delahunt (D-MA), Jim McDermott (D-WA), and Mike Honda (D-CA) introduced landmark legislation [PDF] on Thursday that will provide security for investments in the renewable-energy sector by guaranteeing rates for renewable-energy generation. This policy mechanism, also known as a national feed-in tariff, may be the single most effective tool to expand renewable energy development that we know of. Feed-in tariffs have been introduced in several U.S. states, but none have the bills have been passed into law.

The International Energy Agency, the European Commission and the United Kingdom’s Stern Review have determined that feed-in tariff policies in Germany, Spain, France and other European Union countries have achieved larger renewable energy deployment at lower costs, compared with policies in other European Union countries.

The legislation has two principle titles. The first would streamline interconnection standards and the patchwork of policies currently governing interconnection. The second title addresses the actual process of setting of renewable energy tariffs, and what would qualify. This bill would not only apply to the mom and pop backyard wind turbines, and rooftop solar - the tariff extends to projects as large as 20 megawatts!

The San Francisco board of supervisors has approved the country’s largest municipal solar program. The program is designed to reduce the cost of solar for city residents and leverage private dollars to get more solar on San Franciscans’ roofs (earth2tech).

GM is backing a hydrogen refueling station near Los Angeles. The station will be located at Clean Energy’s compressed natural gas (CNG) facility and should be operational by the fall (gas 2.0).

U.S. Representative Jay Inslee (D-WA) will introduce a national renewable energy feed-in tariff. Under the bill, utilities would be required to pay a set price to anyone supplying less than 20MW of renewable electricity to the grid. Inslee plans to introduce the bill in the next week or two. But requiring utilities to pay a mandated amount for renewable energy is “a new idea to D.C., and like a fine wine it’ll need time” (ecopolitology).

Conservatives call into question highly successful feed-in tariff

There is a reason that Germany has half of the world’s installed solar generating capacity, and it is not the Northern European country’s boundless sunshine. Renewable energy capacity has achieved such tremendous growth because of the German government’s aggressive energy policy.

The policy vehicle responsible for the rapid acceleration of the country’s renewable energy capacity, known as a feed-in tariff (FIT), guarantees a fixed-rate of return for homeowners and farmers who install solar, wind, small hydro, biomass, and methane capturing systems and sell their surplus electricity back to the grid. Germany has Europe’s highest feed-in tariffs, allowing consumers to earn around 40 euro cents ($0.62) per kWh compared to paying retail rates of 18 euro cents per kWh after taxes and support fees.

Electricity generated through Germany’s feed-in law produces about 50 terawatt-hours (billion kilowatt-hours) of electricity per year, or nearly 15% of German electricity consumption (1). This adds an average of only 1.01 euros ($1.69) a month to a typical home electricity bill.

Bu, despite the law’s success, conservatives in the German Bundestag want to ratchet back the incentives that support renewable energy development.

Since the energy crisis of the late 1970s, the federal government has employed various policy mechanisms to support renewable energy development. Driving through the neighborhoods that were developed in the late 70s and early 80s, it’s not hard to notice all of the old rooftop solar water heating arrays that were installed because people were taking advantage of a tax credit made available by the Carter administration. But the tax credit expired after Reagan took office, which is why I don’t see rooftop solar hot water nearly as much anymore (at least not recently installed).

The same thing will happen if the renewable energy tax credits expire

Illinois Representative Karen May (D-Highland) has introduced a bill calling for a system of renewable energy “feed-in tariffs” (FITs) like those used in Germany to spur the development of electricity from renewable sources. After its initial reading, HB 5855, The Illinois Renewable Energy Sources Act has been reported to the House Rules Committee for initial action.

Feed-in tariffs have proven remarkably successful throughout Europe, and especially in Germany, where some 55% of the world’s solar power capacity resides. I have covered the nuts and bolts of the FIT here and I have made a short argument for them here (but for a more comprehensive treatment of how and why the policy mechanism works, I recommend visiting the World Future Council’s PACT website, which is a powerful resource for advocates, policymakers, environmentalists, tech geeks and regular folks).

In a nutshell, a feed-in tariff offers a long-term guaranteed price contract (usually about 15-20 years) to any entity that contributes electricity to the grid via renewable sources like solar, wind, biomass, landfill gas, small hydro, geothermal and methane. Whereas existing policy mechanisms like the production tax credit favor large corporations with sizable tax liability, and investment tax credits favor those folks who can afford a large upfront cost that comes with a 20-30 year payoff, this policy tool encourages the distributed generation of renewable energy and it levels the playing field by providing long-term investment security for small businesses, homeowners, churches, schools and others, so they are more willing to make the financial commitment that is necessary for installing renewable energy themselves. This is not to say that our existing RE policy tools of choice (including renewable energy standards) are inherently bad, but they may be insufficient to spark the kind of growth in clean energy the public seems to be demanding.

The diffusion of renewable energy FITs has extended from Northern Europe to include some 47 countries worldwide, but the mechanism has yet to gain much political traction in the United States. The bill is modeled after the legislation proposed in the fall of 2007, when Rep. Kathleen Law introduced HB 5218 into the Michigan House of Representatives.

Ironically, while the eyes of renewable energy policy wonks (yes, there are such a thing) have been looking to California, Michigan and Minnesota for a successful German-style feed-in tariff, Rep. May’s bill took people by surprise.
