Gowanus Canal to Become "Sponge Park" for Storm Water Runoff

As the EPA begins its decades-long superfund clean-up of the Gowanus Canal in Brooklyn, NY, a landscape architect has plans to make the cialis online pharmacy canada area a beautiful, natural sponge for storm water runoff. The designs for creating the Sponge Park out of the 1.8-mile long canal was just approved by the city's Design Commission on January 30.

The first phase of the park has begun, which will include a series of bioswales leading up to a bioretention basin at the end of Second Street. These initial natural elements will allow the park to absorb 4,500 cubic feet of water from Second Street on a rainy day, which easily meets the demands of nine out of 10 typical storms that shower New York, without the need for costly new underground tunnels and viagra tablets sale tanks. The cost of traditional storm water infrastructure upgrades is a major motivation for the viagra 30 discount city to try and implement some new, greener options.

The next phase will include planting a variety of plant species that can handle large amounts of rain, periodic drought and also help remediate the toxicity of the soil surrounding the site. Some of the species that have been chosen include tulip poplars, northern blueflag iris, holly, yarrow, honey locust, American sweetgum, switchgrass, sunflowers and sassafras. The plants will not only serve a great environmental benefit, but also make the current eyesore a nice place to take a walk.

The Gowanus Canal could be just one of 100 of these sponge parks put in place throughout the city over the next 20 years, which could save the city $2.4 billion over traditional storm water infrastructure.

Developing Renewable Energy Resources of viagra pfizer canada buy viagra on the internet Landfill Gas

Landfills are a necessary component of contemporary life. According to the US EPA, the average person in the uk viagra prices U.S. produces nearly 1,130 pounds (513 kilograms) of waste per year, and the vast majority of that ends up in landfills. Much of that trash decomposes, and releases methane and CO2, both of which are greenhouse gasses. However, methane is online viagra prescription also a gas which can be used as a fuel, and increasingly, landfills are beginning to realize this is an energy resource and are making use of it.

At present, landfill gas is the source of power for more than a million homes and of heat for over three-quarters of a million homes in the US. In addition, it is also provides fuel for natural gas-powered vehicles as well as power and generic viagra usa canada heat for industrial process uses. Nearly 600 sites throughout the country are using the mathane from landfills to produce electricity, heat, proces energy, and even pipeline-quality natural gas and compressed and liquified natural gas for vehicle fuel.

Methane is 20 times more potent than CO2 as a greenhouse gas for trapping heat, and landfills are a major source of methane emissions. However, according to the EPA, 60 to 90 percent of the methane produced by a landfill is captured by a typical landfill gas energy project.

Capturing and using the methane from landfills serves the dual purpose of keeping these greenhouse gasses from directly entering the atmosphere and providing an alternative to levitra pfizer canada fossil fuels. These programs have been encouraged through tax credits and grants as well as by the renewable energy portfolio standards many states are adopting for their public utilities.

Even if the volume of waste per capita could be cut significantly, landfills and trash are still going to be present. As with other materials recycling programs, it only makes sense to tighten the cialis canadian drug store loops and take better advantage of the available resources in ways like this.

New Uranium Mines Banned from Grand Canyon Area for 20 Years

The Obama administration has officially banned any new uranium mines in the land adjacent to the Grand Canyon for the next 20 years.  During the Bush presidency, mining companies filed thousands of new land claims in northern Arizona near the national park.  In 2009, Secretary Salazar ordered a temporary ban on any new claims, but now those lands are safe for at least 20 years.

The ban protects one million acres of discount viagra cialis levitra online land surrounding the Grand Canyon from new mining claims, but the 3,200 existing mines will not be affected and 11 new mines already under construction will be allowed to continue to develop.

Although this ban seems like a no-brainer, there was a decent amount of opposition since the price for uranium is high and the area is rich in uranium deposits.  This ban doesn't just protect the beauty of the place, but more importantly the health of the ecosystems and millions of people who live within the cialis 20mg online Colorado River Basin.  At least one creek in the park has been found to be contaminated by uranium and high levels of arsenic have been found in the area from old mining operations.

In Germany, Renewable Energy Surpasses Nuclear and Coal Energy For First Time

In 2011, Germany finally saw their renewable energy production top that of almost all other sources of energy, including nuclear, hard-coal and gas-fired power plants.  The only other energy generation source greater than the renewable energy mix was lignite-fired power.

According to a report from German utility BDEW, renewable energy accounted for 20 percent of the country's total energy output, up from 16.4 percent last year.  Lignite-fired output produced 24.6 percent of the electricity.

Nuclear power is dropping off in the country since Chancellor Merkel closed the eight oldest reactors this past year after the Fukushima catastrophe.  Nuclear represented 17.4 percent of the country's electricity load, down from 22.4 percent last year and where to buy viagra the country plans to step away from the energy source completely by 2022.

Investments in Renewable Energy Topped Fossil Fuels Last Year

For the first time, investments in renewable energy projects surpassed those in fossil fuel power plants, according to Bloomberg New Energy Finance.  Last year, $187 billion was invested in renewable energy installations, while $157 billion was invested in new natural gas, oil and coal plants.

The increase in investments in the sector, even while in a down economy, has led to price drops in equipment and renewable energy power, making solar and wind power far more competitive with coal power.

Renewable energy subsidies deserve a lot of credit for the spending increase:  about $66 billion in subsidies were handed out last year.

It's a great bit of news as another round of global talks on what is the cost of viagra the climate crisis is likely heading nowhere as we speak.
