Vegies with a higher purpose

by INDIRA NAIDOO, The Sydney Morning Herald, December 29, 2013

The Big Apple’s hotels are sprouting gardens.

You know the grow-your-own movement has crossed over into the mainstream when some of New York’s hottest hotels start growing vegies on their roofs.

More than 20 Manhattan hotels now have productive rooftop vegetable gardens. Some have their own beehives producing honey – and some even have chickens laying eggs.

So why give vegie patches million-dollar views in a city where real estate is at a premium?

The trend is two-fold: travellers are expecting more organic, seasonal and local ingredients on hotel menus. And when a hotel guest wants to know the provenance of the food, it doesn’t get any more local than this. Rooftop herbs and vegetables aren’t bruised by transportation and storage, and retain more of their nutrients. And the hotels limit their carbon footprint.

There are financial benefits as well. Green roofs reduce heating and cooling cost for large buildings and mitigate against rain and stormwater damage.

Here’s a look at four New York hotels with impressive gardens.

Le 19 décembre 2013, quelque 9 000 m² du grand jardin de 4,3 ha qui s’étend au-dessus du Forum seront inaugurés au cœur de Paris. Ce nouveau parc aménagé par Seura Architectes commence à révéler la simplicité de sa composition… Inversement proportionnelle à la complexité du site. Il portera le nom de Nelson Mandela.

Ne parlez pas de leur « gazon » aux architectes de l’agence Seura. A quelques jours de l’inauguration, prévue le 19 décembre 2013, d’une portion d’environ 9 000 m² du nouveau jardin des Halles, la pelouse n’est peut-être pas très touffue, mais quand graminées et vivaces auront prospéré, c’est une prairie qui doit émerger du cœur de Paris. Ce nouveau paysage portera le nom de l’ancien président sud-africain Nelson Mandela. A la suite du décès du héros de la lutte anti-apartheid, le 5 décembre dernier, la décision de lui dédier ce jardin sera en effet soumise aux élus de la capitale lors du conseil de Paris de décembre.

Alors qu’à quelques mètres de là, la structure de la Canopée imaginée par l’agence Berger-Anziutti s’est imposée en quelques mois et que la pose des verres de la grande couverture centrale a débuté, le jardin commence ainsi à réapparaître. Seura Architectes, équipe chargée depuis 2004 de la reconfiguration d’ensemble du site des Halles, tant en surface qu’en souterrain, a totalement repensé cet espace vert de 4,3 ha avec le paysagiste Philippe Raguin.

Analysis: Clouds over Hawaii’s rooftop solar growth hint at U.S. battle

(Reuters) – When Gloria Adams signed a contract to install a rooftop solar power system on her Oahu home in late August, she looked forward to lower electric bills and a return on her investment in the years ahead.

She never dreamed that she would have to stop the project, get the Hawaiian Electric Company’s permission before she could proceed, and possibly help pay for any upgrades to her neighborhood’s electricity circuits to handle the extra load.

Her home improvement ran afoul of a rule that went into effect in September.

The regulation requires homeowners on Oahu – Hawaii’s most populous island – to get the utility’s approval before installing photovoltaic (PV) rooftop solar systems.

In areas like Mililani, where Adams lives, the utility’s power circuits have reached a threshold where it would be dangerous to add PV systems without investing in upgrades to the distribution system.

“We didn’t anticipate having to pay HECO when we took this on,” Adams said. “They are acting like they got caught with their pants down, saying, ‘We don’t know how to deal with this.’”

What’s happening in Hawaii is a sign of battles to come in the rest of the United States, solar industry and electric utility executives said. The conflict is the latest variation on what was a controversial issue this year in top solar markets California and Arizona. It was a hot topic at a solar industry conference last week: how to foster the growth of rooftop solar power while easing the concerns of regulated utilities that see its rise as a threat.

1. The average cost of solar panels has gone from $76.67/watt in 1977 to just $0.698/watt today (the second figure is according to PVinsights, and is even lower than the 2013 projected price in the chart below).

Well, that basically tells you everything you need to know right there — the cost of solar panels today is about 100 times lower than the cost of solar panels in 1977 (even more than 100 times lower!) — but I promised 10 charts, so let’s dig in even further and throw on some other fun charts and graphs.

Catching sunlight, to sell it

Xcel seeks to charge solar panel owners for using the grid, wants more homeowners to buy solar power from Xcel

DENVER — More than 200 protesters gathered in downtown Skyline Park last Wednesday to amp up, march to Xcel Energy headquarters and deliver a petition signed by 30,000 Coloradans in favor of rooftop solar. The energy company recently announced it wants to charge Coloradans with rooftop solar for using the Xcel infrastructure grid — even if they’re using it mainly to provide power to other Xcel customers.

It’s not only solar-panel owners that oppose this idea, said Annie Lappe of the Vote Solar Initiative. “Four out of five Coloradans believe ratepayers with solar should get a fair credit for the energy they put back into the system. That means those same Coloradans also oppose Xcel’s proposed changes.”

The issue of how much solar owners are paid for the energy their homes kick back to the grid came to a head when Xcel submitted its 2014 green energy compliance plan to the Colorado Public Utilities Commission (CPUC). The plan proposed changes to so-called net metering. The proposal would draw credits from a fund specifically for green energy encouragement and it would ask future solar-installers to pay for their occasional use of the private grid Xcel owns and operates.

“It’s not a question of whether we incentivize rooftop solar, but how we do it,” said Ethnie Treick, manager of Policy Analysis at Xcel. “How do we provide solar energy to the most people?”

Renewable energy support schemes now present in 127 countries, report finds

by IAN CLOVER, PV Magazine, 28 August, 2013

The Worldwatch Institute — an independent research organization based in Washington D.C. — reports that 127 countries worldwide have now enacted support schemes for renewable energy.

A trends report by the Worldwatch Institute has found that 127 countries worldwide now have renewable energy support schemes in place – up from just 48 as recently as mid-2005.

The report’s author, Evan Musolino, drew the analysis for his “Vital Signs Online” trend from data gleaned from “REN21’s Renewables 2013 Global Status Report”, which he co-authored.

In this latest work, Musolino also reports that 99 feed-in tariff (FIT) policies are currently in place worldwide at either national or state/provincial level, while quotas requiring a specified minimum share of renewable energy power production are evident in 76 countries; up from just 34 in 2004.

Despite the economic downturn leaving a number of countries mired in recession and hamstrung by shrinking budgets, investment in renewable energy development and expansion has generally followed an upward trend, particularly in the solar photovoltaics industry, which has seen module costs fall by as much as 80% since 2008, and 20% since 2012.

At the beginning of this year, 66 countries offered tax incentives on renewable energy development, the report finds. And as the technology has proliferated, so has regional diversity.

In the middle of the decade, 58% of countries that enacted renewable energy support schemes were located in Europe and Central Asia. Today, that figure is slightly more than a third of the global total, with East Asia and the Pacific (21%), and Latin America and the Caribbean (LAC) following closely.
