Green Options

Earlier this month, Governor Schwarzenegger signed legislation to buy solar power from relatively small private generators for rates above market value. Hawaii is next in line with this European-style tariff — the Hawaii Public Utilities Commission and Governor Lingle just recently set a similar initiative for Hawaii.

Hawaii’s initiative will make it possible for homeowners and businesses to sell power they generate from small to medium-scale renewable energy projects (i.e. solar panels) to Hawaii’s main power producers at higher than market-value rates.

Governor Schwarzenegger just gave solar power a boost in California, especially for relatively small-scale solar generators.

Taking notes from Europe, perhaps, Schwarzenegger signed legislation for a “feed-in tariff” earlier this week that requires Calfornia utilities buy solar power from relatively small generators and at higher than market-value prices.

The first large scale biogas plant linked to a beef feedlot, could make a more significant contribution to renewable energy in South Africa than the planned 3.8 MW of electricity, by advancing the technology in South Africa.

The Business

Independent power producer (IPP) Lesedi Biogas Project (LBP) is planning to build one of the world’s largest open-air feedlot manure-to-power plants, in Heidelberg, near Johannesburg, South Africa. Such plants use the anaerobic fermentation (bacterial fermentation of organic waste, with little or no oxygen present) to produce a methane rich gas which can be used to produce electricity or burn for heat.

The plant will be situated at the Karan Beef feedlot, which will supply the manure from its feedlot to the LBP. This would initially amount to 110,000 tons per year of manure, which would allow the production of 3,8 MW of base-load power reaching 6,2 MW of peak power.

SMUD has introduced a Feed-in Tariff to pay producers for renewable energy beginning in 2010. The Sacramento Municipal Utility District is the nation’s sixth largest publicly owned utility, with 1.4 million customers in Northern California.

California already does offer a little known Feed-in Tariff or FIT, but the rates are somewhat anemic; paying between $0.08 and $0.19 cents a kWh. The costs to “feed in” are so undefined,  it has few takers, totaling only 14 MW, according to a new NREL analysis of FIT policy design. Of developers and residents who adopt solar; 97% opt for the California Solar Initiative rebate which pays a known amount upfront for estimated production.

Which state makes 15 percent of its electricity entirely from wind power?

Iowa. In 2006, according to the Iowa Utilities Board, wind power provided 5 percent of the state’s electricity. Now, just three years later,  Iowa produces between 15 and 17 percent of its own electricity from wind power.

MidAmerican Energy, Iowa’s biggest utility, pays farmers $3,500 a year (plus 2% increase annually) to rent locations for 102 wind turbines. To scout the best locations, they paid $5 an acre to survey likely farmland, and will pay $10 an acre per year to keep those options open for future additional wind turbines.

Cities around the world should use a mix of energy efficiency measures and affordable renewable energy schemes to reduce their carbon emissions.

As U.S. policymakers debate the best renewable policy for the country, many German experts are already convinced they know the answer: a feed-in tariff. Germany’s feed-in tariff, which offers generous set prices for renewable electricity fed into the grid, stimulated 1.5 gigawatts of new solar capacity last year, and similar programs also have boosted markets in countries such as Spain, Greece, Italy, Turkey and South Korea. All the fastest-growing solar markets in the world today have feed-in tariffs.

Gainesville, Fla., and Ontario, Canada, also recently created German-style feed-in tariffs, but the policy hasn’t yet taken hold as a U.S. state or federal policy. I recently wrote a post for Earth2Tech about the difficulties of implementing a German-style feed-in tariff in California: the policy isn’t responsive to market signals that would encourage electricity generation when and where it’s most needed, it’s more challenging to make work in places with lower conventional electricity prices and widely varying utilities with different restrictions, and it doesn’t address retail electricity or encourage customers to use less energy.

Remember when we had the idea that investing in real estate was a safe bet? It was such a commonplace idea that this would generate a return on the investment, that it became a cliche: “As safe as houses”.

Now, despite our real estate values dropping like a stone, there is still part of your building that you can use to generate a certain return yearly.

That is that abundant farmland [...]

Think of the Czech Republic and you’re more likely to think of beer, castles or Kafka than solar power. But the Eastern European country is one of the world’s fastest-growing markets, says Jenny Chase, a senior associate with London-based research firm New Energy Finance.

The country installed 50.8 megawatts of solar power last year, up dramatically from only 3 megawatts in 2007, she says. The bulk of that capacity — 31.5 megawatts — got installed in December, which represented more than fivefold growth from the 5.81 megawatts installed in November.

Beginning on March 1, residents of Gainesville, Florida with newly-installed solar photovoltaic systems will be able to receive 32 cents per kilowatt hour of electricity produced by their system and added to the regional grid.

A Government-majority Senate Committee has recommended no immediate action to rollout a national renewable energy feed-in tariff to boost investment.
