Methane Emissions From Oil & Gas 27% Higher Than Earlier Estimates

2014EPAInventory2

Originally published on EDF. By David Lyon Methane emissions from the oil and gas industry are significantly higher than previous official estimates, according to draft revisions of the U.S. greenhouse gas emissions inventory released Monday by the Environmental Protection Agency. At 9.3 million metric tons, revised estimates of 2013 emissions are 27% percent higher than [&hellip

Utility-Scale Solar In US Is 31 Times Higher Than 10 Years Ago

June_US_Solar_Gen

The generation of electricity from utility-scale solar projects in the United States during June 2015 was 31 times that of the output from utility-scale solar in June 2005, and now accounts for roughly half a percent of all US electricity production, according to the US Energy Information Administration (EIA). The latest data released by the [&hellip

NASCAR Waves Its Green Flag Higher



NASCAR has its traditions, but innovation is its heart and soul and the organization has just taken another step to prove it. Earlier this week NASCAR (National Association for Stock Car Auto Racing) announced that it was bumping its sustainability profile higher up on the executive  ladder by promoting its current managing director to Vice President, Green Innovation.

That would be Dr. Michael Lynch, who has been with NASCAR since CEO Brian France first announced that NASCAR would be front and center in the green sports movement, back in 2008. Lynch is the guy behind NASCAR Green, which the organization modestly asserts is “the largest sustainability program in all of sports and one of the most powerful and impactful green programs in the public and private sectors.”

Pesky Meddling Government!

You can check out all of the NASCAR Green initiatives for yourself (here’s that link again), but we’re most interested in two of Dr. Lynch’s recent projects. They reach millions of NASCAR fans with a positive message about public-private cooperation in environmental stewardship that is the opposite of the “government is the problem” talking point that has saturated conservative discourse for way too long.

NASCAR steps up NASCAR Green program.

First, in May 2012 NASCAR and the US EPA entered into a Memorandum of Understanding for promoting sustainable products and practices to millions of NASCAR fans. In return for technical assistance from EPA, the agreement calls for NASCAR to ramp up its sustainability efforts in ways that catch the attention of its followers.

That runs the gamut from promoting the Design for the Environment (DfE) label and working on the NASCAR supply chain to adopt the E3 initiative (Economy, Energy and Environment), to encouraging NASCAR concessionaires to adopt more sustainable operations.

Second, NASCAR followed up just this past September by entering into a Memorandum of Understanding with the US Department of Energy.  The new agreement brings DOE’s heavy artillery – its vast network of federal laboratories, research institutions and private sector partners – into the NASCAR fold with the aim of propelling transformative automotive technologies into the mainstream, including electric vehicle charging stations, solid-oxide fuel cells, and advanced biofuels.

The agreement also covers natural gas technologies for NASCAR teams’ long-haul trucks and we’re not fans of (to say the least) shale gas, but if you’re talking landfill gas and biogas then yay.

NASCAR Green

Aside from these umbrella initiatives (including a new partnership with the Natural Resources Defense Council), we’ve been following NASCAR and its affiliated raceways on their trip along the green path.

That includes solar energy, a major tire recycling initiative, and a showcase for the new all-electric Ford Focus EV among many others.

For the record, Formula racing is also about to take a giant leap into greener pastures with the introduction of the new all-electric Formula E series next fall.

Easy-To-Manufacture, Thin-Film Solar Cell With Higher Than 15% Conversion Efficiency Created From Perovskites


Originally published on CleanTechnica sister site Ecopreneurist.

An easy-to-manufacture, thin-film solar cell with a higher than 15% conversion efficiency was recently created by researchers at the University of Oxford through the use of a newly emerging type of semiconductor referred to as “perovskites.” The new devices are simple enough that they could be mass produced rather easily, by utilizing processes such as vapour-deposition — potentially greatly cutting down on costs, according to the researchers.

The “perovskite” semiconductors — organometal trihalide perovskite semiconductors, which have the formula (CH3NH3)PbX3, with X being iodine, bromine, or chlorine — are relatively new to the solar energy field, having been first employed in solar cells only back in 2009. And while those first attempts to utilize them were relatively impressive, those initial results have now been surpassed, thanks to a simpler, new device that possesses a solar-to-electric power efficiency of 15.4% and a large ‘open circuit’ voltage of 1.07 V.

“Our devices have a high solar-to-electric power efficiency of 15.4% and a large ‘open circuit’ voltage of 1.07 V – all in a solar cell in which the absorbing perovskite layer is only 330 nm thick,” states lead research Michael Johnston. “This means that we only need a tiny amount of perovskite material to make a solar cell with good properties.” (Conventional crystalline silicon cells, by comparison, are much thicker — usually ~0.15 mm — and produce less voltage — ~0.7 V under open-circuit conditions.)

“Little is known about the photophysics of these materials, which I think is quite exciting – this is a rapidly evolving field,” Johnston continues. “The fact that we can make such good solar cells using a conventional planar p–i–n architecture indicates that the charge-carrier diffusion lengths (the distances electrons and holes travel before recombining) are long, and that these carriers survive a long time in perovskite. That we can fabricate an efficient device without complex mesostructuring – as was previously the case with solar cells made from this material – also shows that perovskite is very good at both absorbing light and transporting photogenerated charge.”

Physics World provides more info:

According to the researchers, these perovskite-based devices should be cheap to make using processes that are compatible with existing solar-cell manufacturing infrastructures. And since they absorb light in a different part of the electromagnetic spectrum to silicon, the two materials might be used together in so-called tandem cells in which a silicon device would be placed underneath a perovskite one.

The researchers are now working to optimize the technology. Johnston explains: “I think we will see the efficiencies of these devices climbing higher in the near future. Investigations into the fundamental photophysics of the perovskite layers will be particularly interesting and will also help us accelerate the optimization process.”

The new research was published in the journal Nature.
