Renewable Energy Capacity Surging, But America Betting On Shale Gas

Renewable Energy Capacity Surging, But America Betting On Shale Gas | Développement durable et efficacité énergétique | Scoop.it
A report from the Federal Energy Regulatory Commission's Office of Energy Projects says that, in 2012, the capacity for renewable energy electrical generation accounted for almost 50% of all new installations for energy projects in the United States. ...

Stephane Bilodeau's insight:

The amount of renewable energy produced in the U.S. last year was slightly less than the global average of 15%, meaning that America is not too far off the mark compared to the rest of the world.  The UN Framework Convention on Climate Change has set a worldwide goal of 30% renewable energyby the year 2030, but they currently remain pessimistic about the ability of countries to achieve that goal, and believe that there could be at least a nine-percentage point deficit between reality and their goal.

Fossil fuel companies impose more in climate costs than they make in profits

Fossil fuel companies impose more in climate costs than they make in profits | Développement durable et efficacité énergétique | Scoop.it
Climate change impacts exceed fossil fuel profits.

 

It is fairly well understood by now that releasing carbon dioxide and other greenhouse gases into the atmosphere imposes an economic cost, in the form of climate change impacts. In most cases, however, those responsible for carbon emissions are not required to pay that cost. Instead, it's borne mainly by the world's poor and low-lying countries, and of course by future generations, as many of the worst impacts of climate change will emerge years after the emissions that drive them.

 

People sometimes refer to the unpaid cost of carbon pollution as a subsidy, or an "implicit subsidy," to polluting businesses. The IMF recently issued a report saying that total worldwide subsidies to energy, mainly fossil fuel energy, amounted to $5.2 trillion a year. The reason that number is so high is that the IMF includes implicit subsidies — the social costs imposed by businesses (including climate damages) that they don't have to pay for.


Via Alexandre Pépin
Stephane Bilodeau's insight:

"There's been a lot of work recently trying to quantify carbon risk. A new contribution to that conversation was just released by Chris Hope and colleagues at the University of Cambridge Judge Business School: "Quantifying the implicit climate subsidy received by leading fossil fuel companies." It attempts to put a number on the carbon risk facing the world's top 20 fossil fuel companies, the ones most directly vulnerable to a price on carbon. The results suggest that those companies are in a perilous situation.

(...)

The results are pretty startling. To wit: "For all companies and all years, the economic cost to society of their CO2 emissions was greater than their after‐tax profit, with the single exception of Exxon Mobil in 2008" (my emphasis). In other words, if these fossil fuel companies had to pay the full cost of the carbon emissions produced by their products, none of them would be profitable.

 

It's even worse for pure coal companies, for which "the economic cost to society exceeds total revenue in all years, with this cost varying between nearly $2 and nearly $9 per $1 of revenue." Total revenue, Hope and colleagues note, represents "employment, taxes, supply purchases, and indirect employment" — everything that coal companies contribute to the economy. It turns out the costs they impose through carbon emissions are larger than all those contributions combined. (For oil and gas companies, carbon costs generally range from 10 to 50 percent of total revenue.)"

Sustainer Homes creates green, off-grid homes from shipping containers | Stu Robarts | GizMag.com | Développement durable et efficacité énergétique | Scoop.it

Using old shipping containers is seen as an environmentally friendly means of constructing new homes. Taking this one step further, Sustainer Homes has begun making off-grid container dwellings that incorporate self-managed water, sewerage, electricity and gas.

Sustainer Homes argues that factors like rising rents and demand for housing is requiring younger generations to look for more affordable, sustainable and flexible living options. It says its converted shipping containers not only address these issues, but also enable independence from facilities, low-impact living and freedom of mobility.

Les images impressionnantes de la fonte de la banquise attestent d'une accélération au Groenland.


Via Laurent Samuel
Stephane Bilodeau's insight:

Au Groenland, la glace fond à vue d'oeil. Cette année, le thermomètre est passé à 25 degrés au-dessus de 0. Il y a huit ans, pour la même période, le blizzard soufflait et les scientifiques devaient affronter des températures de - 35 degrés. Une amplitude de 65 degrés inquiétante pour les chercheurs qui observent la banquise depuis plus de 25 ans.

L'activité humaine en cause

"Durant ces dernières décennies, cet énorme réservoir de glace qu'est le Groenland a vu sa fonte s'aggraver sans bénéficier de chutes de neige équivalentes pour s'équilibrer", explique Joel Harper, glaciologue de l'Université de Montana. Le Groenland est le deuxième plus grand réservoir en eau douce de la planète et la glace peut atteindre jusqu'à trois kilomètres d'épaisseur. Les chercheurs pointent du doigt les conséquences de l'activité humaine. Plus on monte vers le Nord, plus c'est visible : la glace est noircie par la pollution.

The world’s most famous climate scientist just outlined an alarming scenario for our planet’s future | Chris Mooney | WashPost

The world’s most famous climate scientist just outlined an alarming scenario for our planet’s future | Chris Mooney | WashPost | Développement durable et efficacité énergétique | Scoop.it

James Hansen has often been out ahead of his scientific colleagues.

With his 1988 congressional testimony, the then-NASA scientist is credited with putting the global warming issue on the map by saying that a warming trend had already begun. “It is time to stop waffling so much and say that the evidence is pretty strong that the greenhouse effect is here,” Hansen famously testified. Since then, he has drawn headlines for accusing the Bush administration of trying to muzzle him, getting arrested protesting the Keystone XL Pipeline, and setting forward the case for why carbon dioxide levels need to be kept below 350 parts per million in the atmosphere (they’re currently around 400).

Now Hansen — who retired in 2013 from his NASA post, and is currently an adjunct professor at Columbia University’s Earth Institute — is publishing what he says may be his most important paper. Along with 16 other researchers — including leading experts on the Greenland and Antarctic ice sheets — he has authored a lengthy study outlining an scenario of potentially rapid sea level rise combined with more intense storm systems.

Stephane Bilodeau's insight:

“You can see a lot of different points in this paper, and it’s going to take a while for the community to sort them out, but actually, the story is clear,” says Hansen. The bottom line conclusion, he says, is that sea level rise is “the big impact of human made climate change.”


Michael Oppenheimer, Albert G. Milbank Professor of Geosciences and International Affairs in the Woodrow Wilson School at Princeton University, commented by email that “If we cook the planet long enough at about two degrees warming, there is likely to be a staggering amount of sea level rise.  Key questions are when would greenhouse-gas emissions lock in this sea level rise and how fast would it happen? The latter point is critical to understanding whether and how we would be able to deal with such a threat.

“The paper takes a stab at answering the ‘how soon?’ question but we remain largely in the dark.  Giving the state of uncertainty and the high risk, humanity better get its collective foot off the accelerator.”

Smart cities: Asia's new frontier? | Jean Chua | Eco-Business.com

Smart cities: Asia's new frontier? | Jean Chua | Eco-Business.com | Développement durable et efficacité énergétique | Scoop.it

From London to Lahore, cities around the world are competing to be crowned as ‘the world’s smartest city’, led by a firm belief in the power of technology to make urban centres more innovative, efficient and liveable than they already are.

Nowhere is this opportunity to make cities cleaner and smarter more evident than in Asia, which is already home to 60 per cent of the planet’s people. The region’s cities, along with Africa’s, will account for 90 per cent of the increase in the world’s population from now till 2050. That’s about 2.5 billion people who will be moving to urban centres in those regions.

The smart city is hailed as a way for urban planners to accommodate this growth sustainably. The services and infrastructure around it has grown to a multi-billion dollar industry in Asia alone.

According to a report by market research firm Navigant Research, investment in smart city information and communication technology (ICT) in Asia Pacific will total US$63.4 billion during the period from 2014 to 2023.

Stephane Bilodeau's insight:

Indeed, the mantra of  “sustainability” should guide the development of all smart city projects, emphasises Thomas Menkhoff, professor of organisational behaviour and human resources (education) at Singapore Management University’s Lee Kong Chian School of Business.

In fact, it is no longer an option for city leaders as they confront challenges such as climate change, air pollution, and urbanisation in a world with finite resources, he says.

“A truly smart city will manage to increase sustainability,” Menkoff adds. “Aspirations in terms of eco-smart towns and homes, electric car sharing services, reuse and recycling as well as greener practices in business and society at large are achievable in principle.”

“There is no doubt that the wise use of ICT can lead to a more efficient use of resources, energy savings, and a higher quality of life,” he notes.

Coal investment is the most urgent climate threat | Alex Kirby | Climate News Network

Coal investment is the most urgent climate threat | Alex Kirby | Climate News Network | Développement durable et efficacité énergétique | Scoop.it

The future of coal has come under scrutiny from a perhaps unlikely source – the head of the organisation representing wealthy nations that relied on coal for 32% of electricity generation last year.

Angel Gurría, secretary-general of the Organisation for Economic Co-operation and Development (OECD), said the scale of new investments in “unabated” coal-fired electricity generation − where greenhouse gases are emitted directly to the atmosphere − posed the most urgent threat to the Earth’s climate.

Speaking in London, he said governments should be sceptical about the benefits of coal for their citizens. They should rethink the role of coal in energy supply, and conduct a more rigorous evaluation of its true costs.

Via Chuck Sherwood, Senior Associate, TeleDimensions, Inc
Stephane Bilodeau's insight:

Without new mitigation measures, coal generation is projected to emit more than 500 billion tonnes of CO2 between now and 2050 − eating up around half the remaining carbon budget that scientists say is consistent with keeping a global temperature rise below 2°C.

In any case, Dr Gurría said, countries’ contributions to emissions reductions after 2020 are not consistent with a 2°C pathway. He said the carbon clock was ticking and the Paris COP21 climate conference must give a clear and credible signal that governments are determined to go for a higher level of ambition.

Brazil announces massive reforestation and renewable energy plan with US | Suzanne Goldenberg & Dan Roberts | The Guardian

Brazil announces massive reforestation and renewable energy plan with US | Suzanne Goldenberg & Dan Roberts | The Guardian | Développement durable et efficacité énergétique | Scoop.it

Barack Obama and Dilma Rousseff put climate change at the top of their agenda at their bilateral meeting on Tuesday, with the US and Brazil agreeing to obtain up to 20% of their electricity from renewable power by 2030.

Brazil also committed to restoring up to 12m hectares of forest – an area about the size of England or Pennsylvania – in another attempt to reduce the carbon pollution that causes climate change.

The White House said the initiatives were part of a new US-Brazil climate partnership, loosely modelled on the historic US-China agreement reached during Obama’s visit to Beijing last November, intended to build momentum for a global deal to fight climate change in Paris at the end of the year.

“Following progress during my trips to China and India, this shows that the world’s major economies can begin to transcend some of the old divides and work together to confront the common challenge that we face,” said Obama at a joint press conference with his Brazilian counterpart.

Rousseff also heralded the agreement as a highlight of her trip, claiming it would help progress towards a global emissions reductions agreement at upcoming talks in Paris.

“Climate change is one of the central challenges of the 21st century,” she said. “And we have one important objective, which is, number one, to ensure that the energy mix in our two countries will have a substantial share of renewable sources of energy.


Via Chuck Sherwood, Senior Associate, TeleDimensions, Inc
Stephane Bilodeau's insight:

Rich and poor countries alike have been putting forth their commitments, known as nationally determined contributions, to reduce emissions as part of the treaty, which world leaders hope to finalise later this year in Paris.

Brazil also plans to expand renewable energy sources other than hydropower to between 28% and 33% of its total energy mix by 2030.

And in the electricity sector, the US and Brazil jointly announced intentions to increase their share of renewable, non-hydropower sources to 20% by 2030. Deese said boosting renewables that high in the US would be dependent on controversial power plant emission limits that the Obama administration has proposed.

“We believe that this is an ambitious target, but one that is actually achievable and will create new low-cost opportunities for the American economy,” Deese said. “To achieve it, we’re going to have to continue to hit our marks in implementing the regulations we’ve identified to date.”

Faut-il changer l'homme pour ne pas changer le climat ?

Faut-il changer l'homme pour ne pas changer le climat ? | Développement durable et efficacité énergétique | Scoop.it
ENVIRONNEMENT - Dans un article intitulé "L'ingénierie humaine et le changement climatique" ("Human Engineering and Climate Change," Ethics, Policy and the Environment, 15 (2): 1-16, with A. Sandberg and R. Roache, 2012) qui a reçu un certain écho aux Etats-Unis, mais dont l'accueil semble avoir été discret en France, Matthew Liao considère comme acté l'insuffisance, voire le danger ou l'échec, des perspectives traditionnelles permettant d'empêcher ou de freiner le changement climatique. De fait, selon l'auteur, nous devrions changer notre comportement pour le rendre plus écologique mais nous ne le faisons pas, le marché devrait imposer des taxes plus contraignantes mais la politique échoue à le faire, la géo-ingénierie devrait mettre en œuvre des techniques aptes à diminuer le réchauffement mais ces dernières demeurent hasardeuses. C'est la raison pour laquelle il importe d'examiner une quatrième option : changer l'homme, intervenir sur la base biologique de son existence.

Sans pouvoir entrer plus avant dans le détail des arguments de l'auteur, on peut néanmoins se questionner sur les principes qui sont à l'arrière-plan de cet article. Il est, en premier lieu, permis de se demander si Matthew Liao ne présuppose pas le résultat qu'il veut obtenir. Si l'homme n'est pas assez volontaire pour changer sa conduite, il doit malgré tout l'être suffisamment pour modifier son corps. S'il n'est pas assez conscient du danger que court la planète pour agir éthiquement et politiquement, il doit cependant l'être suffisamment pour se faire objet reconfigurable au nom de l'idéal écologique.

China: As Beijing Becomes a Supercity, the Rapid Growth Brings Pains | Ian Johnson | NYTimes.com | Développement durable et efficacité énergétique | Scoop.it

Every morning at 5:30, Liu Desheng joins a dozen retirees waiting for the express bus to central Beijing from this small city in Hebei Province. They stand at the front of the line but never board, instead waiting as bus after bus pulls up, each picking up 50 people from the ever-lengthening line behind the retirees.

Around 6:30, their adult children arrive. The line, now snaking down the street, has become an hourlong wait. People cut in, and a shoving match breaks out. But the retirees have saved their children this ordeal. When the next bus pulls up, the young adults take their parents’ places at the head of the line and board first, settling into coveted seats for a 25-mile ride that can take up to three hours.

“There’s not much I can contribute to the family anymore,” Mr. Liu, 62, said as his son waved goodbye from a bus window. “He is exhausted every day, so if I can help him get a bit more rest, I’ll do it.”

The Liu family’s commuting habit is a small but telling part of a megacity in the making.

For decades, China’s government has tried to limit the size of Beijing, the capital, through draconian residency permits. Now, the government has embarked on an ambitious plan to make Beijing the center of a new supercity of 130 million people.

 

The planned megalopolis, a metropolitan area that would be about six times the size of New York’s, is meant to revamp northern China’s economy and become a laboratory for modern urban growth.

 

“The supercity is the vanguard of economic reform,” said Liu Gang, a professor at Nankai University in Tianjin who advises local governments on regional development. “It reflects the senior leadership’s views on the need for integration, innovation and environmental protection.”

L'énergie n'y fait pas exception.

Via Somme éco-activités
Stephane Bilodeau's insight:

« Intelligents », les réseaux, pilotés en fonction de l’offre et de la demande, offriront une gestion toujours plus fluide et décentralisée d’une production qui sera de plus en plus assurée par une multitude d’entités interconnectées. Ces dernières conquièrent ainsi une première forme d’autonomie. L’accès à leurs propres données de consommation et à celles relatives au réseau, et les outils de pilotage associés renforcent encore cette indépendance relative, à grands renforts de technologies d’exploitation des big data. A l’heure actuelle, il leur reste toutefois un fil (électrique) à la patte. La production d’énergies renouvelables étant par nature intermittente, les nouveaux producteurs demeurent en effet dépendants du réseau pour revendre leurs excédents, et se fournir lorsqu’ils ne produisent pas assez.

Mais ce verrou pourrait sauter. Les technologies de stockage pour le stationnaire progressent en effet, et des solutions commencent à apparaître. Exemple : les batteries que Tesla envisage de proposer à très brève échéance pour ce type d’usage. N’en doutons pas, si le défi technologique est bel et bien surmonté, la société sera suivie sans tarder par une myriade d’acteurs, tant la demande est forte. Quand on connait par ailleurs le modèle d’une autre entité de la galaxie Tesla, SolarCity, on comprend que deux autres éléments de disruption, la dématérialisation et le déplacement de la valeur, sont aussi à l’œuvre.

36 Prix Nobel appellent à une action urgente contre le changement climatique

36 Prix Nobel appellent à une action urgente contre le changement climatique | Développement durable et efficacité énergétique | Scoop.it

Cinq mois avant la Conférence de l’ONU sur les changements climatiques (COP21), lors de laquelle 195 Etats pourraient adopter le premier accord universel sur le climat, le texte appelle «à prendre des mesures décisives afin de limiter les futures émissions mondiales de gaz à effet de serre ».

Stephane Bilodeau's insight:

"Nous soussignés, scientifiques lauréats du prix Nobel, avons rejoint les rives du lac de Constance dans le sud de l’Allemagne afin d’échanger nos points de vue avec de jeunes chercheurs prometteurs qui viennent comme nous du monde entier. Il y a près de soixante ans, ici, à Mainau, une assemblée similaire de lauréats du prix Nobel de sciences a publié une déclaration sur les dangers inhérents à la nouvelle technologie des armes nucléaires — une technologie résultant des avancées dans les sciences fondamentales.


Jusqu’ici, nous sommes parvenus à éviter une guerre nucléaire, même si la menace demeure. Nous pensons que notre monde est aujourd’hui confronté à une autre menace d’une ampleur comparable. Des générations successives de chercheurs ont contribué à créer un monde de plus en plus prospère. Cette prospérité s’est faite au prix d’une augmentation rapide de la consommation des ressources de la planète. En l’absence de maîtrise, notre demande sans cesse croissante en produits alimentaires, en eau et en énergie finira par dépasser la capacité de la terre à satisfaire les besoins de l’humanité, et mènera à une tragédie humaine générale. Déjà, les scientifiques qui étudient le climat de la terre constatent l’impact des activités humaines."

[Video] Prince Charles: To limit climate change we will need to see profound changes

[Video] Prince Charles: To limit climate change we will need to see profound changes | Développement durable et efficacité énergétique | Scoop.it

As you are all very well aware, even if many others may not be, 2015 is a vital year for the future of humanity. Targets, plans and timetables being agreed this year, in Addis Ababa, New York and Paris, will be absolutely critical in ensuring peoples’ – and Nature’s – long-term health, wealth and security. So we must all hope and pray for the right outcomes.

China, Brazil, and the U.S. all unveil new climate goals

China, Brazil, and the U.S. all unveil new climate goals | Développement durable et efficacité énergétique | Scoop.it
When three of the world's biggest polluters pledge to do more to rein in their climate emissions, that's a pretty good day.
Stephane Bilodeau's insight:

The pledge also reiterates China’s intention to halt the rise of its greenhouse gas emissions by 2030, and to get about 20 percent of its electricity from non–fossil fuel sources by that same year, as first announced in a deal with the U.S. in November. That still gives the country 15 years to keep increasing its climate pollution, but Li said China will “strive for the earliest possible peak,” and there are other signs that the country in fact plans to meet and exceed its goals faster than it is committing to. China’s coal consumption has dropped off dramatically. The country is also now one of the world’s biggest investors in renewable energy.

Just a few hours after the China announcement, President Obama and Brazilian President Dilma Rousseff — the leaders of the Western Hemisphere’s two most populous countries — came forward with their own climate announcement. The leaders promised to have their countries running on 20 percent non-hydroelectric renewables by 2030.
