EPA Takes Another Step Towards Regulating Greenhouse Gases

The EPA has taken another step today towards regulating greenhouse gas emissions. The agency formally declared that heat-trapping gases like CO2 and five others were a threat to public health and order levitra on line welfare.

In order to buy online viagra regulate the cialis tablets sale gases under the Clean Air Act, the agency had to prove that the gases endangered the public. The EPA recently announced that it would require companies to start reporting their greenhouse gas emissions and now with today's declaration, regulation could be as little as 60 days away, when the comment period ends on this ruling.

The scientific analysis found that CO2, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons and sulfur hexafluoride were in high concentrations in the atmosphere and that they are very likely causing increased draught, heavy downpours and flooding, more intense heat waves and wildfires, rise in sea levels, more intense storms and harm to water resources, agriculture, wildlife and cheap cialis find ecosystems.

Ecogeeks already know all of this, but having a government agency officially declaring these facts means the the U.S. can more effectively contribute to negotiations over a new international climate treaty. Congress is buy levitra next day delivery drafting climate and energy legislation that will most likely supersede any regulations that the EPA comes up with, but this is a great first step that shows that our government is at least making progress towards protecting the only for you viagra prices planet.

Economic Downturn Has Cleaned Up China's Air

During the economic downturn, we've seen a few environmentally-friendly side effects of all the penny-penching going on. People are focusing more on energy efficiency, they're using their things for longer before tossing them for new versions and now, it seems, China's air is cleaner due to a lack of demand for pollution-causing industries.

China managed to reduce air pollution in Beijing for last summer's Olympics, but since then the air quality has remained improved in the city and the trend is spreading throughout the country. Traffic restrictions and other long-term pollution reduction projectsput in place for the Olympics have continued and the economic crisis has slowed or even stopped production at coal-fired power plants and other polluting manufacturing plants.

The air in Beijing is the only today cheap prescription cialis cleanest it's been in about a decade and levitra on line areas around the country are reporting more blue skies. On average across seven of fast cialis China's largest cities, the number of badly polluted days was halved during the second half of 2008 compared to the first half.

Now that the people of China have had a taste of clean air, let's hope that this will lead to more regulation of emissions and to the development of cleaner technologies so that this fortunate outcome isn't only temporary.



Venice to Use Algae for 50% of Its Electricity

The city of viagra doses Venice has announced a plan to utilize algae in a different way than we're used to hearing about. The Italian city plans to produce 50 percent of its electricity needs from an algae-based power plant instead of fossil fuels.

The water-filled city is turning what has become a nuisance into a renewable energy resource. The city will be producing electricity from two types of algae that are brought in clinging to levitra 20 mg ships and regularly grow over the seaport. The algae will be cultivated and treated in laboratories to turn it into fuel. The fuel will then be used to power turbines in a new 40 MW power plant in the center of the city.

In order to make the new power plant truly carbon neutral, any CO2 produced by the order propica process will be fed back to the algae.

The innovative project will cost the city $264 million and should be operating in two years.

Ocean Iron Fertilization Test Not Successful

Following up on a story we brought to you a couple of months ago, the iron fertilization project in the South Atlantic Ocean has not produced the results expected by researchers.

To recap, the project by British scientists aimed to increase the amount of carbon dioxide-absorbing algae in the ocean off of cheapest tramadol available online South Georgia Island by adding extra iron to the water. Ideally, the extra algae would remove a large chunk of CO2 in the atmosphere and then sink far below the surface, permanently sequestering the CO2.

As expected, great amounts of algae did bloom, but there was an unexpected glitch. Instead of the algae sinking to the bottom of the ocean, they were eaten by copepods, which were then eaten by amphipods, which meant a lot less CO2 was absorbed and sequestered than thought.

Basically, the CO2 that was removed was "almost negligible" as one researcher put it. I guess it's back to the drawing board.

Seawater Could Be Used to Clean Ship Exhaust

The shipping industry, like the airline industry, is responsible for a large chunk of greenhouse gas emissions, but it has been hard to regulate because standards would have to be approved and enforced globally. It hasn't faced much pressure to clean up until the usefull link best levitra price UN and European Union recently began calling for lowered emissions. Luckily, a Singapore firm thinks it has a solution to the problem.

Ecospec has developed a method to remove carbon dioxide, nitrogen oxides, sulphur oxides and soot from ship exhausts with a widely available resource for ships - seawater. The process, called CSNOX, uses electrolysis and ultra-low frequency waves to raise the alkalinity of sea water to a pH of 10 up from 8.1. Seawater is pumped into a tank, the alkalinity is raised and then the seawater is sprayed into the exhaust funnel of the ship. The dirty water is then collected, filtered and processed before being returned to the ocean.

The higher alkaline water is actually to the ocean's benefit since the acidity of very good site cheap levitra online the world's oceans has been rising as CO2 in the atmosphere rises. The water also contains sulphates, nitrates and carbonates that could benefit sea life.

The main objective of Ecospec was to create a process that wouldn't involve chemicals or create secondary environmental issues. One existing method of removing SO2 from ship exhaust has actually been proven to create CO2 as a by-product, which just further contributes to global warming instead of helping. The high-alkalinity of the CSNOX system prevented this effect by neutralizing the SO2.

Ecospec says that the method has already been tested on a tanker and shown to remove 90 percent of SO2, 80 percent of NOx and 75 percent of CO2 from the exhaust. The results earned them the support of the American Bureau of Shipping.

If the process makes it past the levitra tadalafil testing phase, it would cost about $500,000 to $1 million to fit most ships with the system. A small price to pay for removing the cause of 4 percent of global fossil fuel emissions.
