• Ecological greenlash – An ignored calamity

    Posted in Other Stuff on June 4, 2008

    artic.jpg Globalization may have brought the world closer in terms of producing goods cheaper and yet maintaining the costs and quality of the produced product. This however has caused a rampant illness to the eco system of the planet, termed as Ecological Greenlash. Ecological greenlash occurs when human action aimed at increasing the supply of a desired ecosystem service (e.g. food production) inadvertently degrade other ecosystem services (e.g. climatic regulation or pollination) that are essential for the provision of the desired ecosystem service, consequently reducing the supply of the desired ecosystem service. The world is also becoming highly interconnected through the movement of people and the transport of goods locally to globally. Among ecologists, there is an increasing realization that these connections can have profound influences on the long-term dynamics of ecological systems.

  • Tokyo to impose its own carbon emission standards

    Posted in Other Stuff on June 4, 2008

    tokyo_governor.jpg Tokyo will target reducing greenhouse gas emission by a total of 25 percent by 2020 from the 2000 level. Shintaro Ishihara, an acclaimed novelist turned politician, is known for his blunt nationalistic remarks including denunciations of other Asian nations. But he is also known for environmental consciousness and imposed a total ban on heavily polluting diesel vehicles inside Tokyo. He has now proposed a new ‘cap-and-trade’ system to manage carbon emissions in Tokyo, Japan. Under a “cap-and-trade” system starting in 2010, the Tokyo government would require major businesses to reduce carbon emissions while creating an economic incentive by allowing the trade of emissions credits. The move by Tokyo — which with 13 million people is one of the world’s largest cities — is reminiscent of action taken by California, the biggest US state, which launched climate measures despite resistance from President George W. Bush. Japanese Prime Minister Yasuo Fukuda has vowed to push forward action on global warming at the July 7-9 summit of the Group of Eight rich nations. Environmental activists said they hoped the rest of Japan would follow Ishihara on climate change.

    Senate to decide on new emissions bill

    Posted in Transport on June 4, 2008

    global_warming_1.jpg Senate on Monday is to debate a Democratic-backed bill to dramatically cut harmful greenhouse gas emissions by 2050.The bill uses a “cap-and-trade” system wherein the government would cap the amount of pollution a company is allowed to emit — which would be lowered each year — but would also give companies some flexibility by allowing them to buy pollution credits from companies whose emissions fall below their caps. Under the bill, the government would auction off the credits and use some of the proceeds to help consumers who are expected get hit by higher energy costs. The defense thinks these higher temperatures are going to cause terrible problems all over the world — more extreme weather events, vectors that we haven’t seen before. The military people say that it’s going to be a cause of wars in the future. But many Republicans say the bill’s costs are too high. Speaking at a White House event Monday, President Bush warned the additional costs associated with the bill, which he estimated at $6 trillion, would be too much of a burden on the American economy.

    15,000 Plastic bottle raft sets sail for Hawaii

    Posted in Uncategorized on June 4, 2008

    plastic_bottels.jpg A lot of the plastic bottles we consume either end up in land fills or are sadly disposed off into the sea. But since most of us live inland we are unaware of the magnitude at which bottles are disposed of into the sea. A raft build from over 15,000 plastic bottles set sail from Long Beach, CA on Sunday with the intended destination of Hawaii. The trip is expected to last 6 weeks, and was planned to raise awareness around plastic pollution in the Pacific Ocean, a problem that has recently surfaced in the media. Due to ocean currents, a large area of plastic waste (twice the size of the United States) has collected in the Pacific.

    German government set to make billions in carbon trading

    Posted in Other Stuff on June 4, 2008

    Carbon trading is sometimes seen as a better approach than a direct carbon tax or direct regulation. By solely aiming at the cap it avoids the consequences and compromises that often accompany those other methods. It can be cheaper and politically preferable for existing industries because the initial allocation of allowances is often allocated with a grandfathering provision where rights are issued in proportion to historical emissions. Germany is on its way to earn more than $1.55 billion this year in the sale of carbon rights to 12,000 utilities and energy-intensive plants across the continent.

    ElectraTherm – Green energy generated from industrial heat

    Posted in Alternative Energy on June 3, 2008

    electratherm_green_machine.jpg The options we have now-a- days for alternate energy seem to be expanding at a fierce pace. A typical home solar installation can generate between two and four kilowatts, while Google’s solar array at its corporate headquarters–considered the largest in the U.S.–is 1.6 megawatts. Now a company called ElectraTherm has developed a 50-kilowatt machine that uses industrial waste heat as its “fuel.”The machine uses an organic Rankine cycle to heat liquids which are turned into a vapor that turns a turbine to make electricity. The thermoelectric effect has been known since the early 19th century. But the idea of making electricity from heat appears to be getting more attention.

    Italy could soon make Europe Solar powered

    Posted in Alternative Energy on June 2, 2008

    No one knows lighting like the Italians, its no wonder that the best chandeliers are from Italy. The countries energy requirements are rising, like the rest of the world, but it hasn’t been able to get on the solar power bandwagon yet. The hindrance has so far been the confusion over prices and maintenance cost involved. However the mayor in a small town in Milan has managed to light up a cemetery with a photovoltaic plant composed of 18 solar panels, providing the cemetery with free lighting and saving 20% on the billing cost. Enel SpA, Italy’s largest utility, and Sharp Corp., a leader in solar power technologies have joined hands to set up joint solar power generation plants in Italy, which are expected to have an output capacity of more than 160 megawatts by the end of 2011 and supply 81.500 Italian families with energy.

    Norwegian oil company to build World’s first full-scale floating wind turbine

    Posted in Alternative Energy on May 26, 2008

    State-controlled Norwegian oil company StatoilHydro has decided to build the world’s first full scale floating wind turbine, Hywind, and test it over a two-year period offshore Karmøy. StatoilHydro has developed HyWind based on floating concrete constructions familiar from North Sea oil installations. The rotor blades on the floating wind turbine will have a diameter of 80 metres, and the nacelle will tower some 65 metres above the sea surface. The floatation element will have a draft of some 100 metres below the sea surface, and will be moored to the seabed using three anchor points. The wind turbine can be located in waters with depths ranging from 120 to 700 metres.

    Garbage could be the new Bio-Fuel

    Posted in Biofuels on May 26, 2008

    biofuel_logo.jpg Environmentalists today want giant corporations to look for alternative energy resources in trash. Until now, looking for bio fuel meant that precious food crops could become scarce since corporations would want to make the most from it. The best alternative suggested is in converting garbage into bio-fuel, taking care that agricultural waste is only used. Startups like US based Mascoma and Coskata and in Brazil by Brenco and KiOR have already set up refineries that refine waste products like corn stover and sugarcane bagassedo. Coskata’s first biorefineries will use currently available feedstock — wood chips, sugarcane waste and municipal trash. The company estimates that municipal waste could be used to produce 8-10 billion gallons of fuel annually. Industrial waste gases off of steel mills could provide another 10 billion gallons, those gases are exactly what Coskata’s microbes could eat. They’re burning bug food. Coskata is actively approaching steel producers to turn those gases into fuel.

    Data centers switch to intelligent switches

    Posted in Alternative Energy on May 23, 2008

    Not everyone knows about the massive amount of energy that is needed to keep websites online and active. In 2006 U.S. Servers and Data Centers Gobbled Up 61 billion kWh, now that’s a lot considering that most users that time didn’t go beyond checking their emails and maybe watch a few YouTube videos. Today however YouTube isn’t a recent discovery, it now has many competitors diving for attention. Microsoft Research’s Networked Embedded Computing group is working on a very promising concept: A combination of physical sensors in the server room and software algorithms to make individual computers sleep or wake up depending on demand.
