Feed-in Tariffs Contemplated in the U.S.

August 31st, 2009

Policymakers in several states are considering a new tool to boost renewable energy production: feed-in tariffs.

What’s a feed-in tariff? The European Environment Agency defines it this way:

The price per unit of electricity that a utility or supplier has to pay for renewable electricity from private generators. The government regulates the tariff rate.

Indeed, feed-in tariffs are commonly used in Europe to boost renewables, but have been virtually absent in the United States, where renewable portfolio standards and tax incentives are more common inducements.

But some clean-energy advocates have long claimed that the high, fixed-rate payments associated with feed-in tariffs, which help cover the comparatively higher cost of renewables production, are more likely to get the alternative energy industry off the ground.

Last week, the city of Gainesville, Fla., approved what the local paper called the “nation’s first solar feed-in tariff ordinance.”

Gainesville residents with photovoltaic panels on their roofs will get 32 cents a kilowatt-hour when they produce energy. (By contrast, homeowners in Florida last October paid on average 12 cents a kilowatt hour for their electricity, according to Department of Energy statistics.

Other states are investigating feed-in tariffs — including Indiana, Minnesota and Michigan, according to Renewable Energy World.

A bill recently introduced in the Washington state legislature would clear the way for feed-in tariffs modeled on Germany’s.

California’s public utility commission approved a limited feed-in tariff last year and is reported to be looking to expand it.  And Oregon’s governor is also reportedly interested in the concept.

Another Record for U.S. Renewable Electricity

August 20th, 2009

The latest figures from the Energy Information Administration show that net U.S. electrical generation from renewable energy sources (biomass, geothermal, solar, water, wind) reached an all-time monthly high in May 2009.  Combined, those sources accounted for 13 percent of total electrical generation in the U.S., according to recent analysis from the Washington, D.C.-based Sun Day Campaign.

More specifically, Sun Day reports that renewable sources generated 40,395,000 megawatt-hours (Mwh) of electricity in May 2009 (the latest month for which EIA has compiled and released data). That level is 7.7 percent higher than that produced in May 2008 (37,515,000 Mwh) and appears to be the highest monthly figure ever reported by EIA for renewably-generated electricity.

Total net electrical generation in May 2009 from all sources, including renewables, fossil fuels, and nuclear, was 311,411,000 Mwh – a drop of 4.1 percent from the 324,589,000 Mwh generated in May 2008.

The 13 percent share of U.S. net electrical generation provided by renewable sources in May 2009 consists of 9.4 percent from conventional hydropower and 3.6 percent from non-hydro renewables. The latter figure includes approximately 1.8 percent from wind, 1.3 percent from biomass, 0.4 percent from geothermal, and 0.3 from solar thermal and photovoltaics (totals do not exactly equal due to rounding).

Comparing the month of May 2009 to the month of May 2008, net electrical generation from wind sources increased by 12.5 percent; higher wind generation totals in the state of Iowa accounted for 52.2 percent of the national increase. This large increase occurred as 11 new Iowa wind farms began generating electricity at the end of 2008. Conventional hydropower increased by 10.2 percent, reflecting an increase in generation of 2,705,000 Mwh. Solar thermal and photovoltaics combined increased by 3.5 percent.

On the other hand, coal dropped by 14.8 percent, petroleum liquids by 8.3 percent and nuclear by 0.6 percent. Natural gas expanded by 10.6 percent.

“Month-after-month, the U.S. government’s own numbers refute those attempting to dismiss or belittle the rapidly expanding role being played by renewable energy sources in the nation’s electricity supply,” said Ken Bossong, Executive Director of the Sun Day Campaign.  “Moreover, non-hydro renewables are already well beyond the levels of the Renewable Electricity Standard proposed in energy legislation now being considered by before the U.S. Senate, which calls for just 3 percent renewables by 2013.”

For the 12-month period ending May 31, 2009, all renewable energy sources combined accounted for 9.6 percent of net U.S. electrical generation with conventional hydropower accounting for 6.4 percent and non-hydro renewables accounting for the other 3.2 percent. By comparison, for the 12-month period ending May 31, 2008, the corresponding numbers were 8.4 percent, 5.7 percent, and 2.7 percent.

San Francisco Opens The City’s Data

August 19th, 2009

San Francisco has a long history of innovation.  We are home to hundreds of technology companies that are changing the way the world operates from Twitter to WordPress to Kiva.

In an effort to engage our highly skilled workforce we are launching DataSF.org, an initiative designed to increase access to city data.

The new web site will provide a clearinghouse of structured, raw and machine-readable government data to the public in an easily downloadable format.  For example, there will be updated crime incident data from the police department and restaurant inspection data from the Department of Public Health. The initial phase of the web site includes more than 100 datasets, from a range of city departments, including Police, Public Works, and the Municipal Transportation Agency.

We imagine creative developers taking apartment listings and city crime data and mashing it up to help renters find their next home or an iPhone application that shows restaurant ratings based on health code violations.

The idea behind the site is to open up San Francisco government and tap into the creative expertise of our greatest resource – our residents.  We hope DataSF.org will create a torrent of innovation similar to when the developer community was given access to the platforms behind popular technologies and devices like Facebook and Apple’s iPhone.

Our effort to improve access to city data has already led to the creation of new services never imagined within the walls of government. Earlier this summer, our Department of Environment released recycling data that was used by a third party to develop EcoFinder, an iPhone application that helps residents recycle based on their location.

By bringing city data and communities together in one location, we hope to stimulate local industry, create jobs and highlight San Francisco’s creative culture and attractiveness as a place to live and work.

As we look to deepen and broaden citizen engagement we will face common challenges: resistance to change, political will, and sustaining data streams from government sources to name a few.  Collaboration with citizens, non-profits, vendors, academia, and our peers in government will be critical to overcoming these barriers.  It will also take leadership as we’ve seen from President Obama and his CIO, Vivek Kundra to establish our ideals and set forth a shared vision for a more transparent and open government.
