The Brazilian electric utility and wind power developer has placed a $55 million order with ABB to supply three new substations and associated transmission infrastructure in the southern state of Rio Grande do Sul bordering Uruguay, the Swiss multinational announced late last week.
The project contract calls for ABB to supply, install and commission the substations — two turn-key 34.5/138-kV and one 138/500-kV — as well as step-up power transformers and air- and gas-insulated switchgear. The step-up transformers will increase the voltage of wind-generated electrical power so that it can be integrated within Brazil’s grid.
Building Out Brazil’s Wind Power Infrastructure
ABB is also to provision the substations with supervisory control and data acquisition (SCADA) and telecommunications systems, as well as substation automation, control, and protection equipment compliant with IEC 61850 standards.
In addition, ABB is to provide and install two 138-kV overhead transmission lines that will integrate a new 400-MW wind power plant — one of the largest in the country — into Brazil’s national grid. The wind power plant is scheduled for completion in 2014.
At present, the 150-MW Osorio Wind Farm in Rio Grande do Sul is the largest wind power generation complex in Latin America, according to the Brazilian government. The wind power complex consists of three wind farms with a total of 75 2-MW wind turbines installed atop concrete towers 100-meters high.
A growing population — projected to reach 220 million by 2020 — and rapid industrialization is fueling rising demand for electricity in Brazil. The country’s expected electricity generation capacity requirement is forecast to grow to reach some 150,000 MW by 2020, ABB notes.
Slowly, but Surely, Brazil Emerges as a Leading Market for Wind Power
Slowly but surely, Brazil is emerging as leading market for wind power, according to a study conducted by the Global Wind Energy Council (GWEC) and Brazilian Wind Energy Association (ABEEolica). Though wind power growth was small in absolute terms in Brazil in 2010, total installed wind power capacity rose 50% to reach the 1,000 MW threshold.
The Brazilian government’s PROINFA program, which was introduced in 2002, and regulated, regularly scheduled wind power project development auctions, which have taken place since 2009, have been keys to growth of installed wind power capacity in the country, the GWEC notes. As much as 5,000 MW of wind power could be installed in Brazil by year-end 2013, GWEC forecasts.
The Brazilian government’s taken actions to assure that the substantial economic and social benefits of promoting and fostering wind power and renewable energy growth are realized in the country itself.
Brazil’s national development bank, BNDES, shut five of the world’s largest wind turbine manufacturers out from the country’s $3.5 billion wind power market for failing to obtain the legally required 40% of wind turbine components from local suppliers, according to a July 20 Bloomberg report.
Acciona SA, Fuhrlaender AG, Vestas A/S, Siemens AG, and Suzlon Energy Ltd. are no longer eligible for BNDES financing, which effectively shuts them out of the Brazilian market, as such loans are the only source of funding for turbines. Unable to obtain BNDES loans to purchase wind turbines from the manufacturers, wind power project developers will either suspend construction on some projects or switch vendors, according to Bloomberg’s report.

In the long run, there's no avoiding energy storage for a 100% renewable energy society. The two major sources of renewable power are wind and sun, and they are either fickle or reliably not available at night.
The problem is that the simplest energy storage option for electricity is batteries, and this image from Wikipedia (hat tip to Robert Rapier) illustrates a significant technical barrier: our simplest option is also among the least energy dense material we have.
There are two likely paths to a 100% renewable energy future in these circumstances: mass distribution of low-density, low-cost storage, or higher density storage.
In some respects, we're already moving along the first path. Widespread availability of battery-powered iPads and laptops has led to great strides in greater energy density of batteries and lower cost. The following chart (used in our Democratizing the Electricity System report) illustrates the changes in the past 15 years.
Electrified transportation is the next iteration, using batteries that are orders of magnitude larger (e.g. a Nissan Leaf battery with 23 kW-hour capacity has 300 times the storage capacity of a Macbook Pro laptop battery). These are 1st-generation commercial batteries, with enormous improvements in capacity and cost likely. Furthermore, with hundreds of millions of cars, the sheer storage capacity of the U.S. vehicle fleet will be tremendous (over 4 billion kilowatt-hours) as electric vehicles become the drive train standard. And a recent study has shown that the storage capacity of 2.1 million vehicles can enable an additional 10 gigawatts of wind power on the grid (in the Northwest).
The good (or bad, depending on your perspective) news for the U.S. is that renewable energy is such a small fraction of total electricity generation that energy storage isn't yet necessary in any significant quantity. Existing power plants have sufficient spare capacity to fill the gaps left by variable renewables. While this state of affairs doesn't endear the U.S. power industry to environmentalists, it does mean there is time to see storage technology improve.

So what if money doesn’t grow on trees? Researchers at Cornell University have set out to prove that biofuel can grow on willow shrubs, and if their current project bears out,… well you can take that to the bank.
As a commercially viable biofuel crop, shrub willows could put more than one million acres of underused land into production in New York State alone, providing farmers with a new, low-maintenance cash crop while pumping out renewable fuel, too.
A long and winding road for shrub willow biofuel
As with all woody biofuel crops, shrub willow has been facing some stiff obstacles in terms of commercial biofuel production. The primary goal of the research team has been to develop a species of willow shrub that can produce high yields on marginal land, and that project has been going on since 1998.
That’s nothing, according to Cornell researcher Larry Smart. Cited in a recent article by writer Sarah Thompson, he mentioned that “determining the precise genetic mechanisms that produce hybrid vigor has been a scientific challenge for a century.”
Fortunately, things began to heat up earlier this year with $950,000 in new funds for the breeding program from Cornell’s Northeast Sun Grant Institute, along with installation of a new boiler to heat two buildings at the school’s campus in upstate New York. The boiler will burn shrub willow biofuel produced on the campus.
The Sun Grant Institute is partly funded by federal agencies, which came through again last month with a grant of $1.37 million to study the yield and vigor of shrub willow hybrid. That research will leverage new information from the plant’s newly mapped genome.
Shrub willow biofuel and fracking
Aside from demonstrating that shrub willow for biofuel can be a viable cash crop, the new boilers will help show farmers that shrub willow cultivation is also an economical way to produce biofuel for use on the farm.
In that regard, the shrub willow program is part of a broader effort by Cornell and New York State to develop non-fossil fuel resources within the state’s borders. As with the state’s dairy farm biogas initiatives, the goal is to enable property owners to extract more cash from their land in a sustainable way, rather than leasing land for potentially harmful uses such as fracking operations (fracking is a natural gas drilling method that involves pumping chemical brine underground).
The fracking issue is a particularly urgent one for New York State, since upstate reservoirs located in rural areas provide virtually all of the drinking water for New York City, and for a number of upstate communities.
Water contamination from fracking is the main concern. The propensity of fracking to cause earthquakes is also a major concern for New York’s sprawling reservoir system, which involves enormous reservoirs and hundreds of miles of aqueducts.

Any time people are happily stowed away in trunks and hoods, you can rest assured the car is a keeper. Konstantin Othmer’s video showcasing the ten things he loves about his Tesla Model S is cute and gives a good picture of what consumers get out of the vehicle. The music is a touch cheesy, but wait it out to see the rad door handles (yes, door handles) and sweet touchscreen on the dash that even Mr. Magoo could see clearly.

Canadian Atlantic province Nova Scotia has recently given the green light on three commercial wind projects.
Announced on August 2nd by the Nova Scotia Power Advisory, the province's renewable energy body, the three projects announced include:
The three projects will help bring the province’s wind power capacity to 500 MW, while helping to reach the province’s 25% renewable energy target by 2015. Nova Scotia also plans to have 40% of its energy coming from renewable sources by 2020.
“These large wind projects will result in C$200 million in private sector investments that will, in turn, help us meet our cleaner energy agenda,” said Nova Scotia Energy Minister Charlie Parker in a statement.
“Nova Scotia has one of the best wind regimes in North America,” Parker said. “The wind itself is free, and the cost of building wind farms can be spread over many years. The result is a stabilizing effect on electricity rates,” he said.

The institutes will work together to coordinate policies at the national level to achieve a sustainable transport system and enhance capacity of cities to improve mobility with lower carbon dioxide emissions.
Methodologies for appropriate infrastructure and technology options for emission reductions will also be developed by studying the freight movement in each city.
CEPT will focus on inclusiveness and mobility; IIT-D will handle the technological aspects; and IIM-A will make an integrated plan for low-carbon, pollution-free transport system in these cities.
The project will also create an online network for information sharing and coordination to facilitate better cooperation among stakeholders and to encourage public engagement.
India's transport sector is the second-largest contributor of carbon dioxide emissions. Increased vehicular use in recent years has led to increase in congestion, accidents, noise, and local air pollution, particularly in urban areas. Initiatives like this will help to create a model pathway for low-carbon transport in India that can serve as an inspiration to other developing countries.

Analysts are of a view that, by 2016, Ukraine will construct and commission new solar PV facilities with cumulative capacity of 1.8 GW, which is equivalent to the capacity of two nuclear reactors.
According to Macquarie Research’s estimates, Ukraine, which was included for the first time in the forecast, will put in operation 400 MW of new PV capacity each in 2012 and 2013 and 500 MW capacity each in 2014 and 2015.
A draft law, “On Introducing Changes to the Law of Ukraine on the Power Sector," was adopted by the Ukranian parliament last month. According to the new law, private households can sell surplus solar electricity to the grid — Ukrainian power supply companies will be obliged to buy excess electricity from households generated from rooftop solar systems up to 16 kW in size. Households will not be required to obtain a license for electricity production. This law is expected to provide impetus for the development of solar energy in Ukraine.

The Agri-Cube is a POD-sized hydroponic “office” designed by engineers from Japan to produce the maximum number of all-weather veggies with a minimum space requirement, and it comes complete with variable lighting and climate control.
Each one of these efficient Agri-Cube food factories can yield 10,000 fruits and vegetables per year, and provides everything plants need to grow, from lighting that can be adjusted for each type of plant to water recycling (which helps to reduce the Cube’s environmental footprint).
The Cubes run on electricity, of course, but can be equipped to make use of solar panels to generate the electricity needed to run the system. Something like the SolarKiosk‘s panels should do the trick.
You can get a sense of how the Agri-Cube works in the video, below.
The Agri-Cube is expected to cost about 70,000 USD, and is initially being marketed to restaurants, hospitals, hotels, and other businesses that can benefit from a local, consistant source of vegetables. As for me, I’d definitely welcome a few freshly-grown vegetable during the chilly Chicago holidays… all I need now is about $70,000!

It always seems that when the weather is perfect, you just can’t tear yourself away from the computer screen because of work.
Here’s some good news for college students and worker bees from Green Sun Rising: a solar bench that can charge electronics while providing shade.
The cedar and aluminum shelter has thin-film solar panels to catch the rays, and a battery to store excess power for cloudy days. The solar bench makes being locked in a white collar dungeon inexcusable.

The new solar cell was created out of very inexpensive materials, and has been certified at a world-record 7.0% efficiency. That’s a 37% increase in efficiency over the previous record holder.
“Previously, quantum dot solar cells have been limited by the large internal surface areas of the nanoparticles in the film, which made extracting electricity difficult,” said Dr. Susanna Thon, a lead co-author of the paper. “Our breakthrough was to use a combination of organic and inorganic chemistry to completely cover all of the exposed surfaces.”

A study out of Stony Brook University found that compact fluorescent light (CFL) bulbs can damage human skin because of the UV emitted by them. The study is a repeat of a European test which looked at the levels of UV coming through cracks in phosphor coatings on all CFL bulbs.
The researches noted that incandescent bulbs did not affect healthy skin cells.
To combat the harmful emissions from CFLs, researchers suggested avoiding the use of the bulbs at close distances and adding a glass covering.

Nonprofit Organization Advocates Alternative Fuels Sponsoring Six-Time Winner Paul Dallenbach in the August 12th Race
Run a racecar with the sustainable fuel methanol and there's good reason to watch. Next weekend in Colorado, the annual Pike's Peak Hill Climb takes place and two of its competitors will be driving methanol-powered cars that have been backed by Fuel Freedom, a nonpartisan campaign to check American oil dependency by backing flexible fuels such as methanol, which was used successfully in California until 2005.
Originally scheduled for July 8, the race was postponed due to the devastating Waldo Canyon wildfire that was taking place.
Fuel Freedom supports the opening of markets to competition from alternative fuels and is sponsoring methanol-powered cars driven by six-time PPIHC winner Paul Dallenbach and his nephew, Wyatt Dallenbach, in the rescheduled 90th running of the Pike's Peak International Hill Climb.
According to Fuel Freedom, unlike gasoline — which is produced from oil — methanol (wood alcohol) can be made from various feedstocks, including wood pulp, natural gas, plus agricultural and municipal waste.
The Pikes Peak International Hill Climb, located 10 miles west of Colorado Springs, CO features a 12.42-mile course, which includes 156 turns, starting at an elevation of 9,390 feet and ending at the peak's 14,110-foot summit, where the song America the Beautiful was penned.
