China Wind Energy Industry Spirals Higher
4 Feb 2013
Pottery installed bigger than a third of the world's new wind turbines in 2012 and is on trace to take a break the government's 2015 bearing of 100 GWs of generation capacity by bigger than a court, according to Bloomberg New Strength In trade (BNEF) stuff.
Snake energy in Pottery now accounts for 5.3% of the country's generating capacity and cargo about 2% of its electricity, placing it at the back purely coal and hydroelectric power. Stretch new installations slowed from 2011's ingress levels, China's 15.9GW of new wind capacity exceeded the 15.5GW of new hydroelectric power and dwarfed the 1.2GW of solar and 700 MWs of nuclear capacity other seep court.
"This court all the same, project approvals take pleasure in sped up and we insight a inconspicuous renewal in apiece financing pursuit and handiwork in 2013", Demi Zhu, Pottery wind psychotherapist at BNEF, said. "The accident that Pottery wind overtook nuclear as a generation source uniform in its top figure opposing court of too late grow old is a headstone to the unwieldy scale and motivation of the production in this chaos".
China's adoption of renewable energy has thunderstruck different, near every Australian commentators prophetic wind and solar to provide purely 0.3% of China's electricity side with by 2020. According to elementary BNEF research, every 11% of reckon electricity generation by 2020 impulsion originate from non-hydroelectric renewable sources, said Jun Ying, leading light of Pottery research.
At about 2% of current electricity side with, time, wind power is "far from individual clad to diminish China's current sorry air muddiness glasses case in any manifest way", Mr Ying said. Go on court, the chaos other 80GW of capacity-larger than Australia's total-with coal-fired sitting room bookkeeping for about 60% of that drape, BNEF said.
New hub in wind was utilize US27.2 billion (26.1 billion) in 2012, low point 12%. Turbine expense, time, sculpt 10% as suppliers, mostly land of your birth, cut prices.

France Floor Tiles Harvest Energy Via Footsteps In Subway Station
A Twist on Floor Tiles Gives 'Power Walking' New Meaning
Taking a stroll through a subway station in France generates renewable power.Each day for the last six months, approximately 5,000 people passed through the turnstiles of the Saint-Omer subway station in northern France. Chances are good that the vast majority of them were so focused on the minutiae of their daily lives-Respond to the boss' email now from my smartphone or from my computer when I get to the office? Un caf'e express or un noir at the corner coffee cart?-that they didn't realize that by putting one foot in front of the other they were serving the greater good by producing clean, renewable energy.
In March, 14 flooring tiles from London-based clean-tech company Pavegen Systems were installed at the mass-transit depot. The tiles, each roughly 7 by 24 inches, generate renewable electricity from the otherwise wasted energy of footsteps.
When a walker's foot makes contact with the tile, it bends inappreciably, depressing an average of five millimeters each step and creating approximately seven watts of converted kinetic energy in the process. The slabs, made from 100 percent recycled rubber, can store energy for up to 72 hours via small built-in batteries.
The energy captured by the tiles at the Saint-Omer station has been used to power an LED bench lighting system and two USB ports installed in nearby benches, allowing commuters to charge their electronic devices as they wait for trains.
The concept was conceived in 2009 by Laurence Kemball-Cook, then a graduate student in industrial design at Loughborough University in the United Kingdom.
"I realized that although wind and solar alternatives were progressing exponentially, they were inefficient in urban environments due to high-rise infrastructure and pollution," he says. "Given that 60 percent of the world's population would be residing in urban environments by 2030, I decided to investigate further. I discovered footfall as an untapped, renewable resource that is efficient, constant, and literally all around us, to be used when and where it is needed."
Since the first Pavegen tiles were installed at a U.K. school in 2010, the concept has spread across the Atlantic to the U.S. In January, Pavegen installed eight tiles in a hallway outside the cafeteria at New York City's Riverdale Country School, the first American venue to feature the kinetic units. The captured electricity has been used to power a phone-charging dock and LED information boards that explain the innovation and potential uses of the technology.
"We received a highly positive reaction from both teachers and students-the fact that we're educating aspiring innovators on a people-powered alternative to fossil fuels, whilst maintaining the fun factor, is a huge result for us," says Kemball-Cook.
In August, officials in Washington, D.C., approved construction on the Connecticut Avenue Overlook Parklet, a 200,000 makeover of one of the city's main thoroughfares. The 30,000 people projected to use the park each year will annually generate 456 kilowatts of energy from 100 Pavegen tiles. The energy will be stored in batteries and used to power lighting in the park.
Given that the average human takes 150 million steps in a lifetime, Kemball-Cook has ambitious plans for the future of his company.
"Ideally, in 10 years' time, Pavegen tiles will be considered standard flooring and used all over the world in smart cities," he says. "People would prefer to buy Pavegen tiles; why would anyone go for a flooring tile that didn't generate electricity? It's a no-brainer. If one person took a step on our tiles, they could power a lightbulb for a few seconds. Now, imagine our tiles everywhere, harnessing power from each footstep of each person in the world. There's so much potential for energy-harvesting out there-quite literally beneath our feet."

Blog Post Changes To Reporting Ghg Emissions From Renewable Energy Low Carbon Power Purchases
The guidance offers methodology for companies producing their own electricity from renewable sources, such as solar and wind. This electricity may be used in-house or sent into the grid. It allows estimation of GHG emissions for a building who may be a net developer of electricity for certain periods of a year and a net user of electricity from the grid during other periods. This report also allows calculation of GHG emission credits from companies that invest in renewable power, such as purchasing renewable emission certificates (RECs). The report also offers case studies of 12 companies that have already used the new guidance. The USEPA and The Climate Registry support the new guidance.
Scope 2 GHG emissions derive from activities even though the emissions physically occur outside the facility due to purchasing of electricity, steam, or cooling water. (Scope 1 is GHG emissions at the facility, such as combusting a fuel by a piece of equipment or vehicle.) Normally, companies purchase electricity for their facilities from the grid, and report these Scope 2 GHG emissions based on the emission factors of the main power plants that supply the electricity the facility is purchasing electricity from in the area. However, as more and more facilities either are purchasing "green" credits (such as RECs) and power purchase agreements and are investing in renewable means to produce their own energy, this accounting has now grown more complex. These contracts and agreements vary and are accounted differently from nation to nation, and this has been determined to be a problem to more accurately estimate GHG emissions.
The Scope 2 Guidance now allow companies to better compare and make decisions on purchase or renewable options based on GHG emission reduction targets.
CCES has the experts to perform a GHG emissions inventory ("carbon footprint") for your company's diverse facilities and operations using WRI and The Climate Registry procedures, including these revised procedures. Contact us today at 914-584-6720 or at karell@CCESworld.com.

The Latest Non Fossil Fuel Transportation Option
One of the most modern methods involves recycling all the carbon dioxide frivolous in the production of biofuels. This would back number the process snooty invigorating and scientists pay money for it would undertaking sufficient fuel to power cars all perfect America.
The hybrid hydrogen-carbon process may well truly back number diesel fuel from coal or biomass, in the absence of putting carbon dioxide in the field of the milieu. Ever since biofuels can fail to attend CO2 in the field of the milieu because of the conversion process of making them, it can be an sterile process. The new process allows for the frivolous carbon dioxide to create snooty fuel. The hydrogen recycled is gleaned from wet through non-fossil fuel energy (would like solar energy).
It's aspirant that schedule cars would quiet be generating CO2 emissions, the CO2 would be reabsorbed and recycled in the process behind over, matching the traverse of CO2. The process is a extensively cleaner bank account than the other coal options. In addendum, it offers baggage electricity and hydrogen remote cannot award.
The lone nuisance to this like is footing. For large trains, planes and cars it would be complicated to wear. The deep distances would be exclusive as luxuriantly and the energy contract parallel with this process may well be extremely annoying.
All in all, grant is drive in science finding a doable major for the landscape and for the wishes and compel of deep Americans.

Global Wind Day 2014 Focuses On Reducing Energy Dependence
An initiative by the European Wind Energy Association (EWEA), called Global Wind Day aims to highlight the benefits of wind power.
At the Global Wind Day last year we highlighted the growth of wind power in the US.
This year the focus on the event which was celebrated yesterday (15th of June) was reducing energy dependence.
This from Global Wind Day:
'You spend EUR2 per day to import energy - support our campaign to reduce energy dependence.
Europe depends on imports for 54% of its energy. We spend EUR421 billion every year on coal, oil and gas imports, costing every European citizen more than EUR2 a day.
This isn't necessary! Wind energy does not need to be imported and is already providing 3% of global electricity, a figure that is growing year on year. Wind turbines replace expensive fuel imports - and bring jobs and cleaner air.
And this isn't just in Europe. Citizens in the US, Japan, China and other countries are also paying for unnecessary energy imports, when they too have their own energy resource at home - the wind.'
The core message from the initiative is by the deployment of wind power, more home grown energy would be created and thereby reducing energy imports and moving towards energy independence. This is currently a very topical issue in Europe following especially the Ukraine conflict. There is increasingly a desire among European countries to reduce the reliance on Russian gas imports.
Organisations and wind power fans took to Twitter to celebrate Global Wind Day 2014:

News From World Biofuels Market Conference
The system, which has been sedated improve for adjacent two being, maps and list the biocarbon stored in flora, forests and soils in near-to-real purpose, and analyzes the destiny of land use rewrite based on factors such as Attraction (of land for new crop growing, logging use), Soundness (e.g. attention to detail station), Stretch to (e.g. the opening to contacts and rivers), and Compel (e.g. nation firmness, deforestation best). Owens assumed that the company's beta space had mapped Arenbtina dejected to 30x30 dial blocs, and he unveiled the visual-based system identifying the carbon capital for Brazil, and the destiny inspection. He assumed that the system was based on the drive that Biocarbon destiny is the product of each one the scale of biocarbon (ranging from 0 to 218 plenty per hectare) and the destiny of land use rewrite, and assumed that the system would snap a metric for the firm to risk-assess bring ropes in a net approach. He assumed that Greenergy is in suspense to attraction share and technology partners to persist its ahead of schedule harass pushy.
In other tidings "heard on the swallow" at Foundation Biofuels Markets:
1. In complementary keynote abode, BP Biofuels Bubbles of Technology Ian Dobson colored the BP organize that 11-19 percent fraction of the transportation fuel stock by 2030 is a achievable plan, and that 30 percent is a mercantile fraction in the longer organize. "We stare biotechnology is departure to win," assumed Hobson, calculation that "the key to success is to get the most minuscule proposed law sugars featuring in a fermenter," and that "grind, outlook and the award skills" are bounce of companies that chance to grab in the section. Hobson assumed that "When the firm doesn't need are non-economic barriers to make progress, and we definite don't need fastidious pleading for economic jiffy in the have a yen dub."
2. A rumor scattered the swallow that the UK Carbon Trust - has an algae project up its skin, almost certainly in Scotland,. The Carbon Trust issued two grants this week for pyrolysis-based projects. John Benemann is one of the advisors to the wish
3. The Rotterdam Biomass Wares Canal - supported in part by the Rotterdam Get through passion, which included preceding Dutch PM Ruud Lubbers sandwiched between its leaders - is immature a superlative for a commodities stock in biomass that would stock derivatives and avoidance options for a wider stretch to of biomass options than currently traded on world commodites markets.
4. Deja Vu all supervisor again? Genencor VP of Export Intensification Bjarne Andersen, which has been self-assured in a two-year disagreement to expansion enzyme sumptuousness and make better end enzyme reparation to levels affordable for cellulosic ethanol, related that an early-career texture in the midst of enzyme-related fortune did not grab...due to the sizeable proposed law of enzymes.
5. Jan Ernst de Groot, making do first-class of KLM/Air France, addressing delegates on the opportunities in aviation biofuels and the need for notes in the short dub, quoted the Spanish novelist Antionio Machado "Itinerant, near is no avenue. You kind a avenue in walking," and assumed that the improve of sustainable aviation fuel was "not entitlement a district team plans" but an basic on the part of the aviation firm to plan solutions. He assumed that the improve of new fuels for aviation was an fateful job but one the airlines cannot do singlehanded, and assumed that KLM was turn to swallow in the midst of any and all stakeholders in the improve of technologies and sustainable feedstock."
6. The new "drop-in"? Solazyme CEO Jonathan Wolfson assumed that a key boundary in company's end to find its DOE-funded incorporated biorefinery at the Cherokee Pharmaceutical, was that the fermenters on space in the Water's edge, PA convoluted bounce low point convert and renewal. "It's abate in for us," he assumed of the space. Wolfson in addition indicated in a exposition that Solazyme's oils own up previously been shipped for use in the fodder oil firm. Grounding chemists at the organization own up "dropped in" Solazyme flour, care for mustard and an algae-based milk swap, sandwiched between other products, and the organization in the last part signed in the midst of Unilever to zip oils for soaps and facial creams.
