The U.S. wind energy industry had its strongest year ever in 2012 […] installing a record 13,124 megawatts (MW) of electric generating capacity, leveraging $25 billion in private investment,and achieving over 60,000 MW of cumulative wind capacity.

Duane Tilden‘s insight:

In this historic year of achievement, wind energy for the first time became the number one source of new U.S. electric generating capacity, providing some 42 percent of all new generating capacity; the final tally will be released in April in AWEA’s annual report. In fact, 2012 was a strong year for all renewables, as together they accounted for over 55 percent of all new U.S. generating capacity.

“The fact that wind power grew by another 28 percent in 2012 alone and poured $25 billion of private investment into the U.S. last year demonstrates wind’s ability to scale up, and continue to serve as a leading source of energy in America,” Gramlich said.

The global wind energy industry will gather in Chicago, Ill., this May 5-8, 2013, for the world’s largest annual wind power event, WINDPOWER 2013. Thousands of workers and leaders from all sectors will attend to show their wares, attend conference sessions, and seek further solutions for success.

Biofuels groups downplay ruling’s impact on investment – The Hill’s E2-Wire

Biofuels groups are downplaying a Friday federal court decision that some believe could cut off investments in advanced green fuels.

Duane Tilden‘s insight:

The rule requires refiners to blend 36 billion gallons of biofuel into traditional transportation fuel by 2022. Of that total, 21 billion gallons must come from cellulosic and “advanced” biofuels, which are made from non-edible feedstock.

But the court said EPA acted in “excess of the agency’s statutory authority” in projecting refiners could blend 10.45 million gallons of cellulosic biofuel in 2012, as only 22,000 gallons were produced.

[…]

In its lawsuit against the EPA, the American Petroleum Institute (API) argued refiners were forced to buy credits to fill the gap in the agency’s projections and actual production levels.

The court sided with API on that point, giving the oil-and-gas lobby its first victory in its full-court press to repeal the biofuel mandate.

API is pushing Congress to tear down the rule and is fighting the rule through the courts. It also has a lawsuit on file challenging EPA’s projections for 2011.

“We are glad the court has put a stop to EPA’s pattern of setting impossible mandates for a biofuel that does not even exist. This absurd mandate acts as a stealth tax on gasoline with no environmental benefit that could have ultimately burdened consumers,” API Group Downstream Director Bob Greco said in a Friday statement.

As facility managers and building owners prepare for another year of green pushes and renewable energy options, has research determined a winner in the photovoltaic vs. biofuel energy battle?

Duane Tilden‘s insight:

[…] in a paper titled “Spatially Explicit Life Cycle Assessment of Sun-to-Wheels Transportation Pathways in the U.S.” and published in the Dec. 26 issue of the journal Environmental Science & Technology, showed photovoltaics (PV) to be much more efficient than biomass at turning sunlight into energyto fuel a car.

“PV is orders of magnitude more efficient than biofuels pathways in terms of land use – 30, 50, even 200 times more efficient – depending on the specific crop and local conditions,” says Geyer. “You get the same amount of energy using much less land, and PV doesn’t require farm land.”

The researchers examined three ways of using sunlight to power cars: a) the traditional method of converting corn or other plants to ethanol; b) converting energy crops into electricity for BEVs rather than producing ethanol; and C) using PVs to convert sunlight directly into electricity for BEVs.

… “The cost of solar power is dropping, and our quick calculations suggests that with the federal tax credit, electric vehicles are already competitive.”

What does this mean for the future?

“What it says to me is that by continuing to throw money into biofuels, we’re barking up the wrong tree,” Geyer explains. …

EU faces fresh calls to strengthen biofuel rules

Greenpeace-backed report argues EU can meet green transport targets without relying on controversial land-based biofuels

Duane Tilden‘s insight:

NGOs are increasingly fearful that member states’ efforts to meet the targets through an increase in the use of biofuels will have a negligible impact on greenhouse gas emissions and in some cases could lead to increased emissions as companies source biofuels made from food and energy crops that are alleged to have contributed to deforestation and food price inflation.

The EU Commission has acknowledged the risk and last year proposed a new limit on the use of biofuels made from food crops that would ensure such fuels could only count towards half of the 10 per cent target for renewable fuel use.

The proposals have encountered lobbying from some member states who have argued the binding 10 per cent goal cannot be met if limits are placed on the use of biofuels made from food crops.

But the CE Delft report argues the targets can be met through greater investment in fuel efficiency measures, waste and residue-based biofuels, and electric vehicles, alongside tighter rules to phase out the use of biofuels made from land-based food or energy crops.

Could Some Midwest Land Support New Biofuel Refineries?

Millions of acres of marginal farmland in the Midwest — land that isn’t in good enough condition to grow crops — could be used to produce liquid fuels made from plant material, according to a study in Nature. And those biofuels could, in theory, provide about 25 percent of the advanced biofuels required by a 2007 federal law.

Duane Tilden‘s insight:

But some researchers in the field aren’t convinced the resource is nearly that big. Adam Liska at the University of Nebraska in Lincoln says a lot of this acreage is in the Great Plains, which wouldn’t produce a reliable crop year after year.

“One year you may have high rainfall and high crop yields and be able to sustain your facility, [but] the next year you may have a drought,” Liska says.

Indeed, Brent Erickson […] says nobody has plans just yet to use this kind of plant material to make biofuels. […]

“Every region of the country has some form of biomass — so the Northwest would have sawdust and wood waste; the California area might have rice straw or wheat straw, … Refiners in the Midwest are looking at corn cobs, and a plant that’s actually operating in Florida uses dead citrus trees.”

“As this technology progresses we’re going to see a great diversification of biomass supply,” Erickson predicts.

… Timothy Searchinger, an associate research scholar at Princeton University.

The 27 million acres identified in the latest study would provide less than 0.5 percent of our national energy demand, he says. And the more we try to expand biofuels, the more we risk displacing crops for food, or chopping down forests, which store a huge amount of carbon.

Searchinger says Europe has recently recognized those potential hazards and is scaling back its biofuels ambitions.

“They realize that it was a mistake, and their compromise for the moment is essentially to cap what they’re doing and then they promise by 2020 to phase out all government support for biofuels.”

2012 saw the introduction of next generation, advanced biorefineries. Here we look at the trends that will hit the biofuel market in 2013, including; Green Diesel, Decline of Oil,

Duane Tilden‘s insight:

The Retreat of Oil Majors

Trend: Oil Majors double down on “Golden Age of Gas” while narrowing investments across the advanced biofuel space.

An early strategic investor in the advanced biofuels industry, global oil majors have begun trimming excess fat from their biofuel investment portfolios over the past couple of years. BP, a leading investor in the biofuels industry, pulled out of its commercial Highlands Park project in Florida in October 2012 to refocus on R&D efforts. Shell, meanwhile, has dropped a number of investments across the advanced biofuels landscape, concentrating its commercialization efforts on its Raizen joint venture with Cosan in Brazil.

Lower nitrogen losses with perennial biofuel crops

Perennial biofuel crops such as miscanthus, whose high yields have led them to be considered an eventual alternative to corn in producing ethanol, are now shown to have another beneficial characteristic — the ability to reduce the escape of…

Duane Tilden‘s insight:

In the study, funded by the Energy Biosciences Institute, miscanthus, switchgrass, and mixed prairie species were compared against a typical corn-corn-soybean rotation. Harvested biomass and nitrogen, nitrous oxide emissions, and nitrate leaching in the mid-soil profile and through tile drainage lines were all measured.

The researchers found that the perennial crops quickly reduced nitrate leaching in the mid-soil profile as well as from tile lines. “By year four each of the perennial crops had small losses,” Smith said. “Nitrous oxide emissions also were much smaller in the perennial crops–including switchgrass, which was fertilized with nitrogen, while prairie and miscanthus were not. Overall, nitrogen levels were higher for the corn and soybean treatment as well as switchgrass, but were lower for prairie and miscanthus. Prairie and miscanthus levels were lower due to harvest of the plant biomass (and nitrogen) each winter, with no fertilizer nitrogen additions to replace it, as occurred in corn and switchgrass,” she said.

The Hydrélio system will be best used in unused stretches of water, such as quarry lakes, irrigation ponds, water treatment plant lagoons and dams, Ciel et Terre said. “This new floating solar power generation concept addresses the problems of land availability and landscape impacts that large-scale land-based solar power generation projects come up against,” it said. “It makes it possible to conserve land that can be put to other uses, and to convert unused stretches of water into spaces dedicated to renewable electricity production. These stretches of water cover substantial areas.”

Introduction

“My 1976 article entitled “Energy Strategy: The Road Not Taken?” which appeared in Foreign Affairs, suggested two ways in which the energy system could probably evolve over the next fifty years or so, using the United States as an example. If you divided by something like a factor of nine or ten, you would get Canada.”…

“If the U.S. spent only enough on efficiency to keep up with growth and demand for electric services, plus the net retirement of generating capacity, we would have almost enough capital left in surplus to double our rate of investment in durable manufacturing industries.”

The Importance of Electrical Efficiency

“Why do I concentrate on electricity? First, because it is by far the costliest form of energy. Each cent per kilowatt-hour is equivalent in heat content to oil at $17 dollars a barrel, roughly the world oil price. So the electricity we buy, even in Canada where it is quite cheap, is equivalent to heat at many times the world oil price. Therefore saving electricity is more financially rewarding than saving direct fuels. In addition, electricity has enormous capital leverage because central electric systems — the whole systems — are about 100 times as capital intensive as the traditional direct fuel systems (you know, Texas and Louisiana and Alberta oil and gas — the sorts of things on which our economies were built). In fact a quarter of all the development capital in the world goes to electrification.

“Also electricity has huge environmental leverage. Power plants burn a third of the fuel in the world. They account for a third of the CO2, therefore, released from the burning of fossil fuel. In my own country they release two thirds of the sulphur oxides and a third of the nitrogen oxides. What’s more, every unit of electricity you save at the point of use saves typically three or four units of fuel, namely coal at the power plant. And in socialist or developing countries that ratio is more like five or six to one.

So you get the most environmental benefit from saving electricity, as well as the most financial benefit.”
