In breaking news (Saturday, December 8, 11:30 a.m. EST), the United Nations climate change conference has reaffirmed the world’s intention to curb carbon emissions by extending the historic Kyoto Protocol.
This move confirms that most of the world appears ready to attack the growing threat of climate change in a positive way. Though Kyoto is not as robust a framework as many are calling for, its passage signals that we may yet find a way to avoid almost certain climate rearrangements and extinction of species, possibly our own.
The chair of the Alliance of Small Island States, which are most vulnerable to projected sea level rise, reacted to the decision:
The Responding to Climate Change organization attributes the last-minute adoption of the protocol to a reversal of Poland’s stance regarding excess carbon credits, which is shared by Russia, Belarus, Kazakhstan, and Ukraine. A huddle of European Union delegates followed. Also, a number of EU countries and Australia appear to have forgotten to submit their paperwork. Qatar itself may have been instrumental in brokering the deal.
Qatar, Saudi Arabia, Bahrain, and the United Arab Emirates (which represent over 25% of the world's proven oil reserves and 12% of its gas) have committed to submission of Nationally Appropriate Mitigation Actions. They have not yet tied down the scope or timing of these actions. Despite noting that high economic reliance on hydrocarbon production may conflict with national development objectives, the four nations have moved away from the previous tradition of the Gulf states.
Agreement on black carbon emissions and substantial financial pledges from the EU preceded this late development. Litigation due to loss and damage remains an issue for the U.S. However, according to Harjeet Singh, the word “compensation” has been removed from the text after talks among the U.S., EU, African Group, Least Developed Countries, and Alliance of Small Island States.
More news from Qatar will follow.

It definitely does not sound like something you’d want to eat, but a recent laboratory demonstration shows that the resulting solar cells have the potential to produce electricity at a cost as low as 45 cents per watt, far below the grid standard of $1 per watt.
Another Road to Cheap Solar Power
The breakthrough comes courtesy of New Jersey–based Global Photonic Energy Corporation (GPEC) and its research partner, Dr. Stephen R. Forrest, Vice President for Research at the University of Michigan.
The new thin-film solar cell is based on organic photovoltaic (OPV) technology that uses carbon (conventional solar cells use silicon).
Engineering a more efficient solar cell is one key to cutting costs, but commercial-scale manufacturing plays another critical role in the overall cost of solar power. Greater efficiency does not necessarily march in lockstep with lower manufacturing costs, so the trick is to find a balance between the two.
That’s where the partners concentrated their research. The result is a new low-cost manufacturing process that involves using one Gallium Arsenide wafer to produce many solar cells.
Gallium Arsenide is used in conventional solar cell manufacturing, but until that process involves using the same wafer only once or twice, which puts a significant drag on manufacturing costs.
We Built This!
Solar cell efficiency is still a key part of the equation, and this is where GPEC’s decades-long research into “small-molecule” systems has come into play.
However, translating that efficiency into marketable products involves a different skill set, and that’s where the University of Michigan came in. Last year, Dr. Forrest won a grant of $1.5 million from the U.S. Department of Energy to incorporate GPEC’s propriety molecules into a “stacked architecture” that combines high efficiency and high reliability with low-cost manufacturing.
The grant was awarded through President Obama’s SunShot Initiative, which launched last year with the mission of bringing the cost of solar power down to fossil fuel parity within a few years.
SunShot also places a heavy emphasis on reducing the “soft costs” of solar power (installation, permits, grid connections, etc), which DOE estimates can account for about half the overall cost of a solar array.
Location, Location, Location
Speaking of soft costs, when you talk about the installed cost of solar power, it’s also important to account for how it will be used. In the case of GPEC, the new flexible sheets seem to be aimed initially at the market for mobile and off-grid locations, including military equipment and satellites, where installation issues and other soft costs are quite different from those involved in the solar power market for buildings and other permanent structures.
However, the company also has a broader market in mind. Aside from layering the new solar cells onto plastic sheets, GPEC is looking at building-integrated applications such as spray-on solar “paint” and transparent solar windows. The company also envisions using the new technology for solar vehicle paint, solar covers for recharging portable electronics, and solar fabric.

The plants will be turnkey solar power plants designed, engineered, installed, and commissioned by ABB.
ABB will also supply the inverters, protection equipment, switchgear, dry-type transformers, controllers, and the supervisory control and data acquisition (SCADA) system.
“The orders were awarded by two special purpose entities, Core Energy and Erika Energy, whose primary stakeholders include SunEdison, a leading global solar energy services provider," ABB said on Tuesday.
The solar panels used in this project will be supplied by the Chinese firm Flint.
According to ABB: “The two plants will have a generating capacity of 33 MW and 31 MW respectively and will be among the first utility-scale PV power plants to be built in phase one of the South African government's long-term renewable energy programme.”
Both plants are projected to generate 130 GWh per year, which is enough to light 36,000 homes and “displace around 130,000 tons of carbon dioxide emissions a year.”
“We have a strong relationship with ABB and are excited to be working with them on this project,” said Pashupathy Gopalan, Sun Edison Vice President and Managing Director of South East Asia and Sub Saharan Operations.

The country is currently on target to get 1% of its electricity from solar and wind energy by 2015, according to the Emir of Kuwait, Sabah al-Ahmad Al-Jaber Al-Sabah.
“Kuwait relies heavily on oil for power generation but according to the International Renewable Agency (IRENA), the country has approximately 70MW of installed renewable energy capacity. Of this capacity, PV accounts for 10MW and concentrated solar power accounts for 50MW. The remaining 10MW is accounted for by wind.”

Once the facility is up and running, the plant could turn 500,000 tons of garbage into 50,000 tons of green airplane fuel, thanks to Solena's synthesis gas technology that turns it into a liquid hydrocarbon. After the waste gets turned into a gas, it will then get treated through Fischer-Tropsch reactors, which are patented by Oxford Catalyst.
The new plant is all a part of the goals for the airline to have “Carbon Neutral” growth from 2020, while British Airlines Environmental Head Jonathon Counsell could make up 2% of the company’s fuel.
Meanwhile, according to one key official, expect more of these projects to heat up in the near future as the race to make flying more sustainable becomes important. Greenbiz.com reports:

The new tool was created by researchers at the Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab). With it, it becomes possible to see the most minute chemical details, many of which have remained undetected until now. The researchers designed the tool specifically to help them learn more about solar-to-electric energy conversion at the nanoscale, but the technology has great promise for use in every area of nanoscience research.
“We’ve found a way to combine the advantages of scan/probe microscopy with the advantages of optical spectroscopy,” says Alex Weber-Bargioni, a scientist at the Molecular Foundry, a DOE nanoscience center at Berkeley Lab. “Now we have a means to actually look at chemical and optical processes on the nanoscale where they are happening.”
The researchers used their new tool to investigate indium-phosphide nanowires. Because they have a nearly ideal band gap of 1.4 electron-volts, these nanowires are ‘perfect’ for converting the Sun’s light to electricity. What the researchers found was something of a surprise. The nanowires have varied optoelectronic properties along their length, not what had been previously thought. This difference could have a substantial effect on how sunlight gets converted to electricity. The researchers also discovered that the relationship between light and electricity, called photoluminescence, “was seven-times stronger in some parts of a nanowire than others. This is the first time anyone has measured these events on such a small scale.”
Co-author James Schuck, a nano-optics researcher at the Molecular Foundry, adds: “We realized that this is really the optimal way to do any kind of optical experiment one might want to do at the nano scale. So we use it for imaging and spectroscopy but we anticipate many other uses also.”
The paper, “Mapping local charge recombination heterogeneity by multidimensional nanospectroscopic imaging,” was just published in the journal Science.
