Windfarms do not Kill Birds

There have been allegations that wind turbines kill birds and thus are a negative power system overall. Science to the rescue! Ornithologists have completed a study about migratory birds and how well they fare around wind farms. The answer? Birds are fine.

The study, which is published in the Journal of Applied Ecology, was carried out jointly by four naturalists and ornithologists from the RSPB, Scottish Natural Heritage and the British Trust for Ornithology (BTO). It goes against widespread allegations by critics of windfarms that clusters of turbines routinely cause serious damage to wild birds, through collision with the revolving blades, noise and visual disturbance.

James Pearce-Higgins, the lead author and principal ecologist with the BTO, said: “It was a bit of a surprise that the impact on windfarms seemed to be happening during construction rather than operation.”

“It means we should look at ways in which these negative impacts can be minimised. The next step will be to find out whether those steps are effective,” he said.

Fracking Banned in Quebec

People love putting oil in things so much that they’ll cause fracking earthquakes. Quebec has decided there’s no fracking way in their province as the hydraulic fracturing method to get oil out of hard to reach places is too dangerous.

It’s really good to see at least one Canadian province take an educated, knowledge-based, approach to oil.

Quebec issued a temporary ban on hydraulic fracturing pending further study last March, putting a halt to exploration in the province, though companies had expected limited drilling for research purposes. Environ-mental groups, farmers and others in Quebec had spoken out against shale gas development in the province.

The committee will order several more studies with a deadline of next spring, Joly said Tuesday, with the final report targeted for completion some time in 2013. He reported that the committee learned a lot from public hearings held from November 2011 to January 2012 and said there would be further hearings, geared toward specific sectors.

Committee members plan to also travel to Alberta and B.C., and to Ohio, Pennsylvania and New York, where there are also shale-gas deposits.

Bamboo is Super!

Bamboo grows quickly and so to is the market for bamboo. The plant can be used for many different things from building to bicycles, but what’s so great about it today is that more construction sites are aware of how great bamboo is. Bamboo can be used to build stand-alone structures or be used as scaffolding at a construction site – either way bamboo also acts as a carbon sink.

The fast growing rugged grass has “unrivaled capacity to capture carbon” the article claims.

The bamboo industry hails the crop’s other environmental benefits. Because it shoots up quickly – as much as a meter (over 3 feet) in a day – it is highly renewable.

According to the Bamboo Clothing website, it thrives without fertilizers or pesticides, requires little water, grows on slopes too inhospitable for other crops, and has a 10 times higher yield per acre than cotton. Want more? It does not uproot soil (harvesting involves cutting it as it’s a grass) and it’s 100 percent biodegradable, the website notes.

The World Bamboo Organization says today’s bamboo market is $10 billion and could double in five years. China produces about 80 percent of the world’s supply, but other nations are turning to it as a cash crop.

Denmark Increases Green Energy Transition

Denmark is getting looking to have 50% of it’s energy come from wind power and are looking to further their need to import any energy at all. Not only is Denmark looking to lower the need for foreign energy they are trying to decrease the amount of energy that the country uses.

“Denmark will once again be the global leader in the transition to green energy,” said Lidegaard. “This will prepare us for a future with increasing prices for oil and coal. Moreover, it will create some of the jobs that we need so desperately, now and in the coming years.”

The agreement will help Denmark achieve its goal of supplying 100% of its energy from renewables by 2050, including electricity, heating, industry and transport.

What’s in a Lot?

Here’s a challenge from Eran Ben-Joseph: name a great parking lot.

Couldn’t do it, could you? Neither could I, and neither could Ben-Joseph. In a new book ReThinking a Lot: The Design and Culture of Parking he explores the horribleness of all that space that car drivers demand. If you look at North American cities in the 60s and 70s all you’ll see is a giant slab of pavement for automobiles instead of people. Today, those cities are dealing with the car-created destruction.

Where’s the good news in this? Well, Ben-Joseph’s book is all about finding ways to make these wastes of space practical and helpful to the areas around them. Some solutions might be to design a parking lot to serve the local community or to make these parking spots actually green.

So what can be done to make parking lots greener and better integrated into their civic surroundings? Ben-Joseph recommends a menu of ideas to improve parking lots according to their settings — which he regards as “a healthier approach to planning, rather than giving prescriptive ideas about how to design them.”

For one thing, planners might simply plant trees throughout parking lots, as the architect Renzo Piano did at Fiat’s Lingotto factory in Turin, Italy. Low-use parking lots need not be entirely paved in asphalt, either: Miami’s Sun Life Stadium features large areas of grass lots that are environmentally better year-round.
“The whole space does not have to be designed the same way,” Ben-Joseph says. “Overflow parking can be designed differently, and not paved with asphalt.”

Lots can also incorporate green technology. Some parking spaces in Palo Alto, Calif., have charging stalls for electric vehicles. A Walmart parking lot in Worcester, Mass., has 12 wind turbines that generate clean electricity for the store. The Sierra Nevada Brewery parking lot in Chico, Calif., has solar panels built into its lattice structure.
