Iceland’s Renewable Energy Drive is Full-Steam Ahead | National Geographic

Iceland’s Renewable Energy Drive is Full-Steam Ahead | National Geographic | Développement durable et efficacité énergétique | Scoop.it

Iceland is famous for its breathtaking scenery, its geysers, its Blue Lagoon—and for using its abundant renewable energy, and especially for tapping the volcanic roots of the island in developing its geothermal resources.

 

Iceland today generates 100 percent of its electricity with renewables: 75 percent of that from large hydro, and 25 percent from geothermal. Equally significant, Iceland provides 87 percent of its demand for hot water and heat with geothermal energy, primarily through an extensive district heating system.

 

Altogether, hydro and geothermal sources meet 81 percent of Iceland’s primary energy requirements for electricity, heat, and transportation. Iceland has profited by using the low cost of its renewably generated electricity—and the stable price it represents over the long term—to lure a large aluminum smelting industry to the island.

CDP: Eight-Fold Increase in Global Companies Pricing Carbon Since 2013 | Sustainable Brands

CDP: Eight-Fold Increase in Global Companies Pricing Carbon Since 2013 | Sustainable Brands | Développement durable et efficacité énergétique | Scoop.it
Putting a price on carbon is becoming the new normal for major multinationals, with almost 1,400 companies[1] factoring an internal carbon price into business plans, according to a new report from CDP. This represents an eight-fold leap in take up in the last four years, compared to just 150 companies in 2014, and includes more than 100 Fortune Global 500 companies with collective annual revenues of US$7 trillion[2].

Via EcoVadis
Stephane Bilodeau's insight:
The research shows that more than three-quarters of the energy and utilities sectors’ market cap is currently pricing carbon internally, including US industry heavyweights such as National Grid, Exelon Corporation and PG&E Corporation. Over half of the materials and telecommunications sectors also intend to use an internal carbon price as early as 2019.

Pope Francis: Hurricanes show humanity will 'go down' if it does not address climate change

Pope Francis: Hurricanes show humanity will 'go down' if it does not address climate change | Développement durable et efficacité énergétique | Scoop.it
Pope Francis has warned the recent spate of hurricanes should prompt people to understand that humanity will "go down" if it does not address climate change and history will judge those who deny the science on its causes.
Stephane Bilodeau's insight:
As Hurricane Irma was still ravaging the Florida coast on Monday as a tropical storm exacerbated by climate change, Pope Francis doubled down on his condemnations of those who choose to ignore the mounting evidence of the impacts of global warming. Responding to questions from an Italian journalist on board his flight home from Colombia, Francis said that the halting response to climate change reminded him of a “phrase from the Old Testament — man is a fool, a stubborn man who will not see”: an apparent reference to Proverbs 12, a section of the Bible that condemns those who resist correction in matters of knowledge. He also chastised politicians who doubt man-made climate change, saying they have a moral responsibility to act and branding those who do not as “stupid”.

Norway close to becoming planet’s first ‘fully electrified society’ | Développement durable et efficacité énergétique | Scoop.it
Norway has the renewable resources and political will to become the world’s first country to use entirely clean electricity for its power demands, according to a new report by Energi Norge, a non-profit industry group representing Norwegian electricity companies.
Stephane Bilodeau's insight:
Norway’s electrification is set to benefit its closest EU neighbours, Denmark and Sweden, as the Nordic countries’ grids have long been connected. 
The Norwegian grid will soon be connected to the United Kingdom and Germany too, as numerous interconnector projects are currently in different stages of development. NordLink, which would connect Norway and Germany via a 500km-long subsea cable, is due to come online in 2019, while the North Sea Link with the UK is slated to be completed in 2021. There are also plans to link up with Scotland, under the NorthConnect project.

According to a review published in the journal of Theoretical and Applied Climatology. The researchers tried to replicate the results of those 3% of papers that deny climate change—a common way to test scientific studies—and found biased, faulty results.

Katharine Hayhoe, an atmospheric scientist at Texas Tech University, worked with a team of researchers to look at the 38 papers published in peer-reviewed journals in the last decade that denied anthropogenic global warming. “Every single one of those analyses had an error—in their assumptions, methodology, or analysis—that, when corrected, brought their results into line with the scientific consensus,” Hayhoe wrote.

Harvey, Rainfall, and Climate Change  

Harvey, Rainfall, and Climate Change   | Développement durable et efficacité énergétique | Scoop.it

It may be months, if ever, before a formal modeling study is conducted to quantify exactly how much global warming fueled the unprecedented rainfall that drove the historic floods in Houston.

However, we already know quite a lot about how climate change is currently driving trends in extreme precipitation and affecting tropical storms generally. By looking at the trends behind Harvey and examining the simple physics involved, a pretty clear picture emerges — and it is extremely disturbing. One preliminary expert estimate puts the contribution of global warming to the record rainfall at up to 30%.

Our weather is now profoundly different. Record-breaking rainfall is a classic signature of climate change. And global warming is now helping to fuel deluges around the world.

Via Chuck Sherwood, Senior Associate, TeleDimensions, Inc
Stephane Bilodeau's insight:
"A climate change attribution study on last-year’s tropical depression that delivered 1,000-year rains and drove historic floods in Louisiana found that climate change most likely doubled the odds for that event to occur.[
As the global average temperature increases, so too does the ability of the atmosphere to hold and dump more water when it rains.[10] Atmospheric water vapor has been increasing.[
The observed increases in water vapor and extreme precipitation have been studied and the fingerprint of global warming in these trends had been formally identified."

Fossil fuel subsidies are a staggering $5 tn per year | John Abraham | Développement durable et efficacité énergétique | Scoop.it
John Abraham: A new study finds 6.5% of global GDP goes to subsidizing dirty fossil fuels

Via Catherine Kargas
Stephane Bilodeau's insight:
"Fossil fuels have two major problems that paint a dim picture for their future energy dominance. These problems are inter-related but still should be discussed separately. 
First, they cause climate change. We know that, we’ve known it for decades, and we know that continued use of fossil fuels will cause enormous worldwide economic and social consequences. 
Second, fossil fuels are expensive. Much of their costs are hidden, however, as subsidies. If people knew how large their subsidies were, there would be a backlash against them from so-called financial conservatives. A study was just published in the journal World Development that quantifies the amount of subsidies directed toward fossil fuels globally, and the results are shocking. The authors work at the IMF and are well-skilled to quantify the subsidies discussed in the paper."

Leading business group presents a commercial case for delivering the UN Sustainable Development Goals — Cambridge Institute for Sustainability Leadership

Leading business group presents a commercial case for delivering the UN Sustainable Development Goals — Cambridge Institute for Sustainability Leadership | Développement durable et efficacité énergétique | Scoop.it

22 September 2017 – Delivering the UN Sustainable Development Goals (SDGs) is imperative for business growth, continuity and stability, according to a new report published today by the University of Cambridge Institute for Sustainability Leadership (CISL) and a group of leading companies including Marks & Spencer, Jaguar Land Rover, Hammerson plc, Tetra Pak, Novo Nordisk and Keller plc.

 

Achieving the United Nations SDGs will be both a unique opportunity and a profound challenge. A compelling business narrative and a systemic approach are required to help shift current thinking about economic progress towards models that deliver sustainable development. Without this shift, business commitment is unlikely to be sustained and rewarded with commercial success.

 
Stephane Bilodeau's insight:
The University of Cambridge Institute for Sustainability Leadership has identified at least eight business-led approaches that have the potential to promote systemic change towards an economy that delivers the SDGs. 

Align the core business with sustainable outcomes 
1 Acknowledge the need for change and position the business for a sustainable future. 
2 Experiment with sustainable business models. 
3 Treat the SDGs as a holistic agenda. 

Demonstrate leadership on key issues and build followership 
4 Take an early lead on the most material issues and communicate your ambition to others. 
5 Set a vision for a sustainable sector and build the evidence for others to follow. 

Create space for innovation, collaboration and leadership 
6 Bring the key parties on board to create a better conversation and collectively intervene. 
7 Bring people along on the journey. 
8 Help governments raise the bar.

De Blasio Vows to Cut Emissions in New York’s Larger Buildings

De Blasio Vows to Cut Emissions in New York’s Larger Buildings | Développement durable et efficacité énergétique | Scoop.it
Mayor Bill de Blasio announced a proposed plan that would require buildings with more than 25,000 square feet of space to be more energy efficient.
Stephane Bilodeau's insight:
Mr. de Blasio said that the owners of smaller buildings would be offered low-interest loans. But of larger landlords, he said, “They can handle it.” Buildings that do not meet the requirement would be subject to fines, based on the size of the building and the degree to which they exceeded the energy use thresholds. A 30,000-square-foot building that substantially exceeded the threshold could be fined $60,000, according to a news release from the mayor’s office. Of the 23,000 buildings that are larger than 25,000 square feet, officials said that 14,500 are “the worst performing” in terms of energy efficiency, according to the news release.

Renewable energy generates enough power to run 70% of Australian homes

Renewable energy generates enough power to run 70% of Australian homes | Développement durable et efficacité énergétique | Scoop.it
Renewable Energy Index shows sector will generate power to run 90% of homes once wind and solar projects being built in 2016-17 are completed
Stephane Bilodeau's insight:
Renewables, which made up just 7% of national electricity output a decade ago, accounted for 17.2% last financial year. This jumped to 18.8% last month.

This is saving the power sector from carbon pollution equivalent to taking more than half of all cars in Australia off the road, according to Green Energy Markets. The biggest single source of renewable power remained hydro-electricity (40%), followed by wind (31%) and rooftop solar (18%), the index found. Less than 2% came from large solar farms, suggesting the best is yet to come from this arm of the renewables industry which has an array of large-scale projects underway.

Green Energy Markets analyst Tristan Edis said the emergence of renewables, in particular wind and solar, as a “significant source of power” had ushered in a “construction jobs and investment boom”.

What Scientists Know About Climate Change and Hurricanes: QuickTake Q&A

What Scientists Know About Climate Change and Hurricanes: QuickTake Q&A | Développement durable et efficacité énergétique | Scoop.it
These days, as soon as winds hit 74 miles per hour or barometric pressure drops below 990 millibars, people want to know: Is climate change behind this hurricane? It’s an even more pressing question when a giant storm like Harvey is followed by an even more gigantic one like Irma, which itself is being followed by Jose and Katia. Climate scientists continue to wrestle with the connection between global warming and individual storms, but they’re more confident than ever that there’s some linkage.
Stephane Bilodeau's insight:
1. Is climate change to blame for Harvey and Irma? 
Climate scientists are increasingly comfortable connecting global warming to the unprecedentedly high ocean temperatures that fuel some storms. Scientists in Germany and the U.K. drew a direct link between global warming and the intensity of Irma and the destructiveness of Harvey. Climate change can’t be blamed for the existence of these two juggernauts -- there have always been hurricanes, after all -- but it does shape the remarkable conditions they’re occurring in. The fuel for tropical storms is ocean heat, and each storm’s top winds have a theoretical speed limit, determined by how much of that fuel is in their tank. 
2. How hot is the ocean? 
Hotter than at any previous moment in recorded history, thanks to human-driven climate change. The global average sea-surface temperature for July was 1.24 degrees Fahrenheit above the 20th century average, making it the third-hottest July for oceans, behind 2016 and 2015. The waters where Irma was born were about 2 degrees Fahrenheit above normal or 1 degree Celsius.

How ‘Decent Work’ And Climate Resilience Grow Together

How ‘Decent Work’ And Climate Resilience Grow Together | Développement durable et efficacité énergétique | Scoop.it
Whilst climate change has disruptive and sometimes devastating consequences, confronting it has great potential for job creation. Good jobs. Decent jobs that provide livelihood, protection and dignity. The kinds of jobs that ensure sustainable and inclusive growth. The ILO calls these "green jobs."

Via EcoVadis
Stephane Bilodeau's insight:
We must learn to recognize these opportunities and design strategic environmental policies driven by a decent work agenda. There is an urgent need for green employment policies in: 

1) Prevention—before disasters occur 
2) Mitigation—transitioning to clean energy 
3) Adaptation—waste recycling, and reusing of materials such as plastic. 

This process of change at work will require the combined efforts of governments and of employers and workers through social dialogue. Day by day, workplace practices, skills, product design and job profiles are being adjusted. Most automobile manufacturers produce more fuel-efficient (or electric) cars; farmers apply more climate-resilient growing methods with organic fertilizers; enterprises use more energy-efficient techniques. 

This new working dynamic makes a strong case for thinking in terms of processes to enable the greening of economies and production, rather than a dichotomy between unsustainable, dirty jobs being discontinued, and sustainable, clean ones being created.

The Voyager record might be the only physical remnant, the last lonely evidence that we, too, once lived in this city of stars, among these islands of ice and rock.

The good news is that, in many organizations, there’s already someone poised to lead the charge: sustainability managers. 

Traditionally, sustainability managers have focused on developing stakeholder and environmental strategies for companies, but they must now expand their influence to the fields of innovation and technology. Specifically, it is time for sustainability managers to step up and take on challenges in four critical areas: 
1. Ethical issues: from big-data problem to big impact 
2. Workforce education: from losing jobs to gaining meaning 
3. Innovation: from mistakes to “best failures”

"Si le réchauffement climatique n'est pas contenu d'urgence et si des mesures d'adaptation appropriées ne sont pas prises, environ 350 millions d'Européens pourraient être exposés tous les ans à des phénomènes climatiques extrêmes dangereux d'ici à la fin du siècle", soulignent-ils.

Ils ont par ailleurs analysé 2.300 catastrophes survenues durant la période 1981-2010 (type de catastrophe, pays, année, nombre de morts) pour estimer la vulnérabilité des populations à chacun de ces phénomènes. Les vagues de chaleur seront le phénomène le plus meurtrier, provoquant 99% des décès liés aux événements extrêmes, estiment les chercheurs. Le nombre de morts qu'elles entraînent pourrait "augmenter de manière exponentielle", grimpant de 2.700 à 151.500 par an (+5.400%).
