Could America’s New Energy Abundance Spark a Trans-Atlantic Environmental Race to the Bottom?

Could America’s New Energy Abundance Spark a Trans-Atlantic Environmental Race to the Bottom? | Développement durable et efficacité énergétique | Scoop.it

“Affordable energy,” as I explained in detail here, has always been a myth. Low end-user prices for energy are “affordable” only in the sense that they shift the cost to pollution victims. Far from reducing total costs, the shift is a negative-sum game: the winners gain less than the losses suffered by those who are harmed.

The alternative would be a race to the top, in which all the major trading countries would raise energy prices to an appropriate level. Doing so in a coordinated fashion would not greatly disturb existing competitive relationships. Some sectors of the U.S. economy, like those based on gas and renewables, would gain, although coal users and exporters would probably suffer.

Great article in Economonitor on how cheap energy in the States is leading to a race to the bottom. The choice should be for a race to the top, incorporating societal costs of energy into the big picture.

Smart Cities: Technology, Sustainability & Innovation for a Better World

Smart Cities: Technology, Sustainability & Innovation for a Better World | Développement durable et efficacité énergétique | Scoop.it

They only occupy two per cent of the Earth’s land mass, but cities today use a huge amount of the planet’s natural capital, consuming 75 % of global resources and generating 80 % of global greenhouse gas emissions.

As the world population grows to 9 billion by 2050, the number of those living in urban areas will swell by 3 billion to 6.3 billion. With demand for energy and resources set to spike on the back of urban population growth, smart cities have emerged as the modern answer to the wave of urbanisation sweeping across the globe.

 

What defines a smart city?

Put simply, smart cities integrate diverse technologies to reduce its environmental impact. Using a more formal definition from a recent report by the United Cities and Local Governments, smart cities use new technologies, innovation and knowledge management to become more liveable, functional, competitive and modern, bringing together six key fields of performance: the economy, mobility, the environment, citizenship, quality of life and management.

Stunning Satellite Images of Earth

Stunning Satellite Images of Earth | Développement durable et efficacité énergétique | Scoop.it

Of all the cosmic bodies studied in the long history of astronomy and space travel, the one that got the least attention was the one that ought to matter most to us—Earth.

That changed when NASA created the Landsat program, a series of satellites that would perpetually orbit our planet, looking not out but down. Landsat was built for public monitoring of how the human species was altering the surface of the planet. The space agency, along with the U.S. Geological Survey (USGS), has accumulated a stunning catalog of images that, when riffled through and stitched together, create a high-definition slide show of our rapidly changing Earth, which for the first time date all the way back to 1984.

 

These Timelapse pictures tell the pretty and not-so-pretty story of a finite planet and how its residents are treating it — razing even as we build, destroying even as we preserve.

An Integrated Perspective: the 2013 Global Energy Architecture Performance Index Report

An Integrated Perspective: the 2013 Global Energy Architecture Performance Index Report | Développement durable et efficacité énergétique | Scoop.it
The new Global Energy Architecture Performance Index Report ranks energy systems of 105 countries from an integrated economic, environmental and energy security perspective.

The findings reveal that high-income countries have proven best at managing the transition to a new energy architecture. Norway ranks in first place in the index, where a strong energy policy coupled with multiple energy resources has delivered cheap, plentiful and relatively clean power and generated large national revenues.
However, the index also finds that high-income and rapidly growing countries alike often underperform across a wide range of environmental sustainability metrics. With demand for energy rapidly increasing at the same time as some nations are reconsidering costly renewable obligations and CO2 targets, the report calls for affirmative action to address this.

Stephane Bilodeau's insight:

The scale and complexity of the global energy industry demands a country-by-country approach to managing change,” said Arthur Hanna, Managing Director, Energy Industry, Accenture, and a Member of the World Economic Forum’s Global Agenda Council on New Energy Architecture. “The Energy Architecture Performance Index helps nations take stock of their energy architecture challenges and identify specific focus areas coupled with best-in-class examples to use when managing their transition.

World Supplies of Non-Renewable Resources, Visualized [Environmental Infographic]

World Supplies of Non-Renewable Resources, Visualized [Environmental Infographic] | Développement durable et efficacité énergétique | Scoop.it

Politicians and oil companies might waste time debating whether or not we’ve reached peak oil. What they ignore is that we run out completely in under 40 years’ time, by which time a third of the planet’s biodiversity will be lost.

In the meantime, tantalum, that great mainstay of mobile telecoms, will last only a few years more and run out just in time to celebrate the planet breaking the 2oC barrier in 2060.
There’s so much more words could say, but this, a very relevant and informative environmensl visualization, says is so much better...

How Much Is the Internet's Electric Bill? [INFOGRAPHIC]

How Much Is the Internet's Electric Bill? [INFOGRAPHIC] | Développement durable et efficacité énergétique | Scoop.it
The data centers that keep the Internet running require an incredible amount of electricity every year ... and they waste most of it.


While surfing the web, you’re probably more concerned with the charge left on your laptop’s battery. But how much power does it require to keep the Internet itself running?

Powering worldwide data centers for major web companies like Google and Amazon is a huge undertaking. Between the servers and their cooling systems, 'data barns' consume 30 billion watts annually, about 1.5% of global electricity. And at the rate the Internet is growing and adding users, expect that to rise significantly in the next several years.


Are these centers being run efficiently? What toll does it take on the environment just to make sure your Facebook status (and a billion other Facebook users’) reaches the masses?

A Man-Made, Net-Zero Energy Island Off the Coast of Istanbul

A Man-Made, Net-Zero Energy Island Off the Coast of Istanbul | Développement durable et efficacité énergétique | Scoop.it
A proposal imagines 300,000 housing units built into six hyper-energy efficient domes.

This year Istanbul Design Week goes back to the future with a very ambitious project: HavvAda, a cutting-edge net-positive-energy residential island conceptualized by New York-based Studio Dror.

HavvAda, will be built off the shore of Istanbul using excavated soil from a new massive canal planned between the Black Sea and the Sea of Marmara.


For the design, Dror has drawn on spatial geometry, as well as Buckminster Fuller’s legacy in structural engineering and Ebenezer Howard’s Garden City. Six months of intensive dialog with a team of experts have allowed Dror to realize an ambitious concept that offers a high quality of life and helps the environment.

The island is envisioned as a landscape of six residential hills, surrounding a circular valley dedicated to parks and recreation, supported by a mega-dome structure, allowing for a “three-dimensional grid” that aims to maximize energy and structural efficiency.


Read the complete post to learn more about the process and design of the integrated renewable energy system, water recycling, as well as efficient heating and cooling (which allow the community to produce more energy than it consumes).

Also, read further to find additional images and diagrams of how these systems and concepts function in the context of this innovative and ambitious project.

Sustainable Development - Infographic: Inclusive Green Growth | Développement durable et efficacité énergétique | Scoop.it
Why is inclusive green growth necessary?

The world's population is predicted to reach 9 billion people by 2050, and they will all need food, water, and energy to survive. Our current growth patterns are highly inefficient and stand in the way of truly sustainable development. The way forward is inclusive green growth that is clean in its treatment of the environment, efficient in its use of natural resources, resilient, and meets the needs of all people.
