The effects of climate change could hit closer to home earlier than we realise, but false optimism is masking truths that we need to confront

 

 Having spent the last three weeks on the road in the US and Turkey soaking up the latest news on sustainability, there is not a lot to be positive about.

I spoke to climate scientists, business leaders and activists, and the challenges we face appear even more gargantuan then I had thought and, by comparison, progress on addressing them infinitesimal. And that's before superstorm Sandy struck the eastern board of the US.

Getting up close and personal to what is going on around us is something we all could do with, because without the emotional connection to what is happening in the world – it can just feel like a string of words, easy to dismiss.

How best to deal with the numerous sustainability challenges we are facing?...

Energy Use a ‘Major Factor’ in Investment Decisions for 63% of Building Sector

Energy Use a ‘Major Factor’ in Investment Decisions for 63% of Building Sector | Développement durable et efficacité énergétique | Scoop.it
Energy usage plays an important role in most building-sector companies’ investment decisions, and is a major factor for 63 percent of survey respondents, according to an Economist Intelligence Unit report.

Energy efficiency and energy savings: a view from the building sector, also found the majority of companies are replacing inefficient lighting (57 percent), HVAC systems (50 percent) and building insulation (50 percent) with more energy-efficient products. Four in 10 are taking this a step further and rethinking their buildings’ design to maximize natural light.

If half of U.S. consumers don’t know what a ‘smart meter’ is, how are they supposed to engage? | The Energy Fix | Développement durable et efficacité énergétique | Scoop.it
In its third survey by the Collaborative of at least 1,000 consumers throughout the U.S. since 2011 reflecting the U.S. demographics, 54% of Americans who are heads of households and at least 18 years old have never heard of the “smart grid”. Considering that a handful of utilities began rolling out smart grid programs in 2010 with new, digital, “smart” meters by and several are nearing complete deployment, this may come as surprise or a major disappointment.

Thermal Technologies for Biomass Conversion

Thermal Technologies for Biomass Conversion | Développement durable et efficacité énergétique | Scoop.it

A wide range of thermal technologies exists to convert the energy stored in biomass to more useful forms of energy. These technologies can be classified according to the principal energy carrier produced in the conversion process. Carriers are in the form of heat, gas, liquid and/or solid products, depending on the extent to which oxygen is admitted to the conversion process (usually as air).
The three principal methods of thermo-chemical conversion corresponding to each of these energy carriers are combustion (in excess air), gasification (in reduced air), and pyrolysis (in absence of air).

The power of China's strolling eco-warriors | Développement durable et efficacité énergétique | Scoop.it
Prominent environmental campaigner Ma Jun considers what might happen if China does not take heed of environmental concerns.

China has witnessed remarkable economic successes over the last three decades, accompanied by industrialisation and urbanisation. But ordinary people are coming to understand that this comes at a cost.

Citizens are beginning to see that development based on ever-greater consumption of resources is unsustainable. When China's new leaders take control, they will be confronted with a population increasingly protective of their environment.

NASA Satellite Sees Ghostly Remains of Vanishing Arctic Sea Ice

Sea ice swirls in ocean currents off the coast of Greenland (NASA/GSFC) Spooky spectral swirls of last season's sea ice drift in currents off the coast of Greenland.

As global temperatures rise — both over land and in the ocean — thinner sea ice builds up during the Arctic winter and thus more of it melts during the summer, a pattern that will eventually lead to an ice-free Arctic if trends continue. The past several years saw sea ice in the Arctic below the 1979-2000 average, with this past September displaying the lowest volumes yet recorded.

How Solar-Based Microgrids Could Bring Power to Millions | MIT Technology Review

How Solar-Based Microgrids Could Bring Power to Millions | MIT Technology Review | Développement durable et efficacité énergétique | Scoop.it
Millions of the world's poorest lack power. Microgrids could be a clean-energy solution.

 

" Worldwide, one and a half billion people lack electricity, most of them rural dwellers. (In India, for example, 268 million people are without electricity in rural areas, but only 21 million in cities.) The International Energy Agency says the type of power plant installed at Batu Laut, known as a hybrid microgrid, will be essential to bringing power to many of them. That's because connecting a remote community to the conventional power grid, with its large, centralized plants, is expensive and can take more than a decade. In some cases, geography and economics may never permit access to the grid. Hybrid microgrids can provide dependable electricity by intelligently combining power from multiple local sources, and building them is far cheaper and faster than extending the grid to the areas where most of the people without electricity live. "

Le changement climatique, grand absent de la campagne

Le changement climatique, grand absent de la campagne | Développement durable et efficacité énergétique | Scoop.it
Changement climatique ? Le mot n'a pas été prononcé pendant la campagne électorale. Et même pas pendant l'un des trois débats télévisés alors que le phénomène avait été évoqué dans tous les exercices similaires depuis 1988. Dans une interview à MTV le 26 octobre, le président Obama s'est lui-même déclaré "surpris" de ne pas avoir été interrogé sur ce thème.

En même temps, lui qui s'efforce de défendre une approche qui inclut un soutien aux énergies nouvelles, a pris implicitement acte de son échec à vaincre les résistances de la société actuelle. "Nous n'avançons pas aussi vite que nous le devrions. C'est un problème que les générations futures vont devoir affronter, encore plus que la génération précédente."

Ten Ways We Can Help Keep NYC From Drowning Under Water

Ten Ways We Can Help Keep NYC From Drowning Under Water | Développement durable et efficacité énergétique | Scoop.it
Superstorm Sandy brought unprecedented levels of flooding to areas across the Eastern seaboard. New York City and the Jersey Shore were particularly hard hit. In Manhattan, a record-breaking storm surge reached 14 feet, shuttering one of the largest transit systems in the world.
Although climate change did not cause the storm, a growing number of researchers say that climate change increases the severity of hurricanes, including stronger storm surges like the one in Manhattan. This on top of rising sea levels, which will leave many cities, including New York, partially underwater, means just one thing: To save our cities, we need to slow climate change.

New green design methods to revolutionize the building industry... | Développement durable et efficacité énergétique | Scoop.it

If you want a preview of the downtown Vancouver streetscape in 2035, start with a walk down Granville or Georgia Street today.

Most of the buildings will still be standing. There will be additions and replacements, but most of the changes that will transform downtown's living, work and retail space will be undetectable from the sidewalk. That includes upgrades to water and energy systems in buildings that in 2012 are models of inefficiency by contemporary standards, let alone future ones.

"If you are thinking 2035, realistically 80% of the buildings that will be in existence at that time have already been constructed," said Innes Hood, a professional engineer and senior associate with Stantec Consulting, a consulting firm with 12,000 planners, architects, engineers, project managers and experts, working in teams to break down the boundaries between designers, contractors and investors, while using advanced computer modelling programs.


Retrofits are crucial.

One of Hood's main assignments is overseeing the redevelopment of existing buildings. More often than not, that means uncovering, through energy audits, glaring examples of waste - air leaks, inadequate insulation, inefficient heating and ventilation systems.

"We are involved in residential projects where we can achieve 80-per-cent reduction in energy use and become essentially greenhouse gas neutral through the implementation of cost-effective technologies," Hood said. "We're not having to strive to the leading edge. These are tried and true technologies around good building enclosures and high-performance mechanical systems such as heat pump technology...

Green and Healthy Buildings: monitoring consumption & ecology in the built environment

Green and Healthy Buildings: monitoring consumption & ecology in the built environment | Développement durable et efficacité énergétique | Scoop.it

According to the United Nations Environment Programme, buildings account for approximately 40 percent of worldwide energy use and are responsible for 30 percent of greenhouse gas emissions. They also play an important role in the health and wellbeing of those who inhabit them each day.

The mass of information about what makes a building green tends to concentrate on new and innovative designs that create beautiful photo spreads. While such examples are inspiring, they make up a very small percentage of all buildings in operation.

Green Buildings Alive is an environmental initiative aimed at collecting and sharing data on existing buildings between 10 and 60 years old. The data is collected from office towers in Australian Central Business Districts (CBDs) and shared on a public website.
