Mecanismul de Dezvoltare Curata (CDM) prevazut in protocolul de la Kyoto ar putea lua sfarsit din 2013 in cazul in care nu e ajunge la un nou acord global de reducere a emisiilor de dioxid de carbon, arata un raport ONU.
CDM a prevazut 20,6 miliarde de dolari pentru tranzactionarea cotelor de emisii intre statele sarace si cele bogate in 2009, pentru a ajuta statele dezvoltate sa isi atinga tintele de emisii impuse prin protocolul de la Kyoto.
Pana acum nu s-a ajuns la un acord global care sa inlocuiasca protocolul de la Kyoto, cel mai rasunator esec fiind in cadrul summitului de la Copenhaga, din decembrie. Atunci, aproape 200 de state s-au reunit pentru a discuta conditiile unui nou acord, insa nu au reusit sa cada la intelegere.
Statele semnatare ale protocolului de la Kyoto au cerut ONU sa furnizeze o gama mai larga de optiuni legale pentru a evita un vid politic si legislativ la finalul lui 2012.
“Un vid ar frustra insusi scopul CDM si s-ar opune continuarii lui. Astfel, niciu fel de activitate subordonata CDM nu va putea fi validata sau inregistrata, iar reducerea emisiilor in urma primei perioade de angajamente nu ar putea fi verificata”, a precizat ONU.

Vestas va instala 570 MW de energie eoliana in California
Producatorul danez de turbine eoliene a castigat o comanda record de 190 de turbine pentru un singur sit din California, cu o capacitate de 570 MW, informeaza Reuters.
“Cand va fi gata, va fi cea mai mare ferma eoliana careia i-am furnizat turbine in istoria noastra de 31 de ani, precum si cea mai mare din California” a declarat Martha Wyrsch, presedintele Vestas Americas.
In conformitate cu practicile sale obisnuite, Vestas nu a dezvaluit detaliile financiare ale comenzii, care a venit din partea Alta Wind Holdings, o subsidiara a Terra-Gen Power LLC.
Terra-Gen a declarat anterior ca a incheiat un contract de 1,2 miliarde de dolari pentru patru proiecte de energie eoliana la centrul sau din California.
Comanda vine dupa un alt contract de proportii castigat de Vestas in aprilie, care a cuprins turbine de 1.500 MW, insa acestea au fost cumparate pentru mai multe parcuri eoliene, nu doar pentru unul singur.
Jumatate dintre turbine vor fi livrate la sfarsitul anului, iar restul in 2011.

Hong Kong: Taxa a redus consumul de pungi din plastic cu 90%
Locuitorii din Hong Kong si-au redus consumul de pungi din plastic cu 90% la un an dupa introducerea eco-taxei in magazine si supermarketuri, scrie Earth Times.
Locuitorii metropolei din China obisnuiau sa arunce trei pungi din plastic pe zi pana la introducerea taxei de 6 centi americani la mijlocul anului 2009. Taxa a reusit sa modifice comportamentul locuitorilor din Hong Kong, oras recunoscut pentru amprenta mare de carbon.
Un studiu guvernamental realizat in noiembrie arata ca numarul de pungi din plastic aruncate de chinezi a scazut de la trei pe zi la 1,8 pe zi. Rata este inca mai mare decat cea din Australia, unde un om arunca in medie o punga din plastic zilnic, iar in Irlanda cifra este de 0,9

ABB factory in Finland unveils largest solar power plant in Nordic countries
Thursday, Jul 01, 2010
The largest grid-connected solar power plant in the Nordic countries, built on the roof of an ABB factory, has been powered up during an inauguration ceremony attended by Finland’s Minister of Economic Affairs and dignitaries from academia, industry and business.
The 181 kilowatt (kW) solar power system is on the rooftop of ABB’s low voltage AC drives factory at Pitäjänmäki, in Helsinki, Finland. The electricity it generates is to be used for charging the batteries of the factory’s fork lift trucks, and for cutting energy consumption peaks at the factory.
The solar power plant is the first in Finland to use ABB’s recently introduced string inverters together with a central inverter, both of which are designed and manufactured at the Helsinki factory. The ABB solar inverters are used for converting direct current, generated by solar panels, into high-quality alternating current that can be fed into the power network.
The use of several smaller inverters helps overcome the non-uniform shading across the solar array which is the result of obstructions on the roof and neighboring buildings. As such, ABB string inverters*, rated from 4 to 8 kW, and one 120 kW ABB central inverter** are used in the 1,200 square meter solar module area. All the inverters are connected to the building automation system and can be monitored remotely.
Cutting the peaks
“This system is a good example of the benefits of decentralized electricity production near the place of consumption,” says Antti Suontausta, senior vice president, ABB low voltage AC drives. “Photovoltaic electricity gives added value for users, especially in commercial and industrial buildings where peak consumption can be cut by using electricity generated by a solar power system.”
While Finland is not renowned for its abundance of sunshine, the 181 kW solar power plant is expected to generate about 160,000 kWh per year and will benefit from the region’s long summer days. The electricity generated is equivalent to the annual energy consumption of about 30 residential homes (without electrical heating) and is fed directly to the grid within the factory for powering the battery chargers of the forklift trucks. Any excess electricity is used by other loads within the factory grid.
“Our decision to locate the solar power plant on the roof top of the factory is particularly effective as no additional land is used,” says Jyrki Leppänen, ABB’s market director for solar inverters. “ABB in Finland is globally responsible for the development, production and marketing of solar inverters within the company. With this power plant we get the opportunity to test our inverters with solar modules in cold weather conditions. Furthermore we will be able to test the products compatibility with a building automation system.”
Valuable lessons
The project, which costs approximately 500,000 euros, is partly funded by Finland’s Ministry of Employment and the Economy from its renewable energy system investment fund that invests in future and renewable technologies as part of its strategy to create new technologies and jobs within these sectors.
The system, and the ABB central inverter in particular, is providing ABB with valuable information about the behavior of such plants within Nordic climates which experience cold weather, low sunlight levels and slow night-to-day change over.
The solar modules and a new type of flat roof installation system were supplied by Naps Systems Oy, and its partner Purso Oy which provides the profile system for the module mounting structure.
ABB’s Pitäjänmäki factory is globally responsible for the product development, manufacture, sales and marketing of the solar inverters. It is also home to the world’s leading range of variable speed frequency converters, wind turbine converters and large machines.
*Transformerless, single-phase ABB string inverters feed power collected from solar panels into the grid. They are suitable for small and medium-size photovoltaic systems connected to the public electricity network. The ABB string inverter features a high conversion efficiency, which means more electricity is fed to the grid for higher revenues and a faster return on investment; inbuilt protection, which reduces the need for costly external devices; a compact design that frees-up space for other equipment; and an intuitive and easy-to-read control display that can be mounted within the inverter enclosure or remotely.
**Transformerless, three-phase ABB central inverters feed solar energy into conventional power grids. They are suited for large to medium-sized photovoltaic systems, as well as solar power plants from 100 kW to several megawatts (MW).

City of Sydney adopts plan for more renewable energy projects
The City of Sydney is embarking on a plan to build more renewable energy projects for the city's properties as an alternative to purchasing GreenPower carbon offsets.
A proposal endorsed by council provides for reinvesting $2 million a year spent on GreenPower into renewable energy systems for council buildings and operations.
Sydney’s Lord Mayor, Clover Moore, says the city purchased green power carbon offsets in the past as an interim measure while it was developing low and zero carbon energy programs.
Ms Moore says now the projects are underway, investing this money in renewable energy for the city’s own buildings will accelerate emission reductions and maintain Sydney’s carbon neutral status. She says while GreenPower has served the city well, it can now achieve more through smarter investment in renewable energy generation.
Ms Moore describes the initiative as a “bold move” that complements council’s program to supply Sydney with low carbon energy through localised trigeneration plants. She says over time, this will replace the city’s reliance on coal-fired grid electricity.
Ms Moore says coal-fired power stations are an extremely inefficient and polluting means of providing electricity, with more than two-thirds wasted in generation and transmission.
She says the new strategy is part of council’s work to reduce its emissions by 20% by 2012 through a combination of energy efficiency programs, building energy efficiency retrofits, installing LED lighting and trigeneration.

Poluarea aerului omoara prematur peste 4.000 de londonezi anual
Peste 4.000 de londonezi mor prematur in fiecare an din cauza expunerii de lunga durata la poluarea aerului, scrie Guardian.
Cei care traiesc in centrul orasului respira cel mai poluat aer, arata un raport asupra nivelului de poluare din capitala britanica.
Londra se numara printre orasele europene cu cea mai scazuta calitate a aerului. Rata de mortalitate creste in capitala britanica din cauza concentratiei mari de poluare cu particule fine PM2.5.
Poluarea din aer sub forma unor particule fine provine in special din sursele de combustie, atat domestice cat si industriale, precum si din transport.
Acestea provoaca dereglari respiratorii sau agraveaza bolile aparatului respirator deja existente si cauzeaza afectiuni cardiovasculare.
Zonele din Londra in care se inregistreaza cea mai ridicata concentratie de poluare cu particule fine sunt Marylebone High Street, regiunea City of London, parcul Hyde si King's Cross.
Calitatea scazuta a aerului este considerata una dintre cele mai mari probleme de sanatate publica din Marea Britanie. Potrivit expertilor britanici, in Anglia mor anual peste 50.000 de oameni din aceasta cauza.
