Hangzhou (Xinhua) — In Chinese language, most farmers go “down” to the field to harvest crops, but one farmer from an eastern village in China goes “up” to the roof to reap rice.

Peng Qiugen, a “landless” farmer who transferred his land to a gardening company seven years ago, just harvested over 100 kg of rough rice on his 120-square-meter rooftop this week.

“My greatest wish is to save more land for China by promoting rooftop farming to more households,” Peng told Xinhua.

He calculated that a roof as large as his, if used for growing vegetables, can meet the daily demands of 20 people.

In Peng’s village, Qilin in east China’s Zhejiang Province, most farmers have circulated their land to scale planting individuals and companies in exchange for a steady income and an opportunity to try out other jobs that would presumably bring more economic gains.

Some have become factory workers, others have started businesses. For Peng, he has tried both and more, saying, “I accept any jobs within my ability that can improve the living conditions for my family.”

A wealthier material life, however, has never changed his passion for land and farming.

When he started to build his four-story house in 2006, he thought about transforming the roof into a piece of arable land.

Elevated park at trade center site comes into view

The World Trade Center’s best-kept secret has finally come to light.

It is an elevated park, slightly larger than an acre and 25 feet above Liberty Street, that will command a panoramic view of the National September 11 Memorial when it opens to the public, probably in 2015.

Liberty Park, as it is called, is meant to offer a pleasant and accessible east-west crossing between the financial district and Battery Park City; to create a landscaped forecourt for the new St. Nicholas Greek Orthodox Church; to provide a gathering space for as many as 750 people at a time; to allow visitors to contemplate the whole memorial in a single sweeping glance from treetop level; and to serve as the roof of the trade center’s vehicle security center.

For the moment, the park is an empty concrete expanse. The pedestrian bridge over West Street that will connect it to Battery Park City — the bridge that survived the Sept. 11 attack — currently falls several yards short of its future landing spot.

While the general outlines of the park have been known for years, the Port Authority of New York and New Jersey has been sparing in its public discussion of the project, in part because not every detail of its design and construction has been settled.

But the Port Authority’s hand was forced somewhat last month when sumptuous images of St. Nicholas Church and Liberty Park appeared on the website of the architect Santiago Calatrava, who is designing the church. The park was rendered in sufficient detail that it was possible for the first time to understand its basic design. […]

Arizona’s new fee puts a dent in rooftop solar economics

Last week, Arizona regulators gave the state’s largest utility, Arizona Public Service, the authority to charge homeowners with solar panels on their roofs a fee for plugging into the grid and in some cases, selling electricity back onto it. Beginning next year, homeowners who install rooftop solar systems will have to pay a monthly levy — the first ever in the U.S. — equal to $0.70 per kilowatt of installed capacity.

That’s well below the $8 per kw that APS had initially sought. Depending on how big their home system is, the fee will end up costing consumers anywhere from $3 to $6 a month, according to a report by Bloomberg New Energy Finance. APS had hoped to be able to charge about $50 a month per home. The 18,000 rooftop solar systems already present in APS’s service territory will be grandfathered; only those installed after Dec. 31 will be subject to the levy.

“This is a body blow for the Arizona solar industry, not a knockout punch,” says Stefan Linder, an analyst with Bloomberg New Energy Finance. “While this fixed fee will cut into the economics of residential solar, for many homeowners it will still make financial sense to go solar.”

The Solar Energy Industries Association claims that a typical rooftop solar system saves a homeowner about $5 to $10 per month; other estimates put it closer to $20.

The decision by the Arizona Corporation Commission is the first stab at resolving a contentious fight that’s been brewing for years between the solar industry and public utilities. Arizona, the second-largest solar market in the U.S., behind California, has been viewed as a critical battleground in deciding whether utilities would be able to squeeze money out of homeowners who no longer buy electricity from them — and in many cases, actually get paid for pushing supplemental power generated by their solar panels back onto the grid.

Résumé

Contrairement aux boulevards et aux monuments, les toits de Paris, loin des images de carte postale, font partie d’un monde méconnu, inaccessible pour la plupart des habitants et des touristes de la ville lumière. Mais quelques privilégiés ont fait de ce jardin secret leur univers quotidien. C’est le cas de Thomas, funambule qui cherche à capter avec son appareil photo l’âme de la capitale. Michaël Blassel est quant à lui l’un des rares à pouvoir accéder au dôme des Invalides. Benjamin Mouton, architecte en chef de Notre-Dame, ouvre les portes de ces lieux interdits au public et raconte l’histoire de la capitale, à travers ses toits, en évoquant leurs couleurs et les matériaux qui les composent. Rencontre également avec ceux qui souhaitent faire des toits un haut lieu de la nuit parisienne.

De quoi la transition énergétique est-elle le nom?

Le mot énergie est communément utilisé comme si son sens n’était pas sujet à discussion. Pourtant, ses multiples acceptions ouvrent à des réflexions et des choix divers. Accolé à transition, il devrait davantage, selon l’ingénieur et architecte Frank Boutté, interroger les possibilités plutôt que résonner comme un prédiction.
