Shell Oil Invests in Solar Startup to Boost Enhanced Oil Recovery

Shell Oil Invests in Solar Startup to Boost Enhanced Oil Recovery | Développement durable et efficacité énergétique | Scoop.it
Shell Oil recently became the second oil company to invest in solar energy to tap crude in older wells, putting $26 million into busy startup GlassPoint Solar.
Stephane Bilodeau's insight:

"In the complex world of enhanced oil recovery (EOR), sometimes low-tech trumps high. Case in point,


1) Royal Dutch Shell recently became the second oil major to invest in solar energy to coax heavy crude from older wells. Along with with two other investors, they’ve pumping $26 million into busy California startupGlassPoint Solar, because its low cost technology works so well in the dusty, dirty and often remote terrain of oil exploration

 

2) At the same time, competitors Chevron and Bright Source built a rival 27MW project just miles away (watch video), which used 3,822 expensive and unprotected heliostats, consisting of two 10′ x 7′ mirrors mounted on a steel pole.

New research reveals extreme oxygen loss in oceans during past climate change | Sarah Moffitt

New research reveals extreme oxygen loss in oceans during past climate change | Sarah Moffitt | Développement durable et efficacité énergétique | Scoop.it
Sarah Moffitt: During global warming after the last ice age, we found evidence of extreme oxygen loss in the oceans
Stephane Bilodeau's insight:

Sarah Moffitt of Bodega Marine Lab at the University of California at Davis studied a sediment core drilled from the ocean floor that provided a record of this abrupt climate shift.

 

AUDIO: http://www.yaleclimateconnections.org/2015/05/lessons-from-an-ancient-climate-shift/

 

MOFFITT: “What we found is that sea floor communities are really, dramatically disturbed by abrupt oxygen loss and abrupt climate warming.”

 

It’s an effect that scientists fear is happening again. Only marine creatures with extra-large gills and other special adaptations can survive in low oxygen zones, so current climate trends may put many ocean species at risk.

Why tying CEO pay to sustainability still isn't a slam dunk

Why tying CEO pay to sustainability still isn't a slam dunk | Développement durable et efficacité énergétique | Scoop.it
A small but increasing number of publicly traded companies are integrating sustainability with executive compensation. But will others really follow?
Stephane Bilodeau's insight:

“We see that this is a means to create a sustainable competitive advantage,” said Royal DSM North America CEO Hugh Welsh. “Going forward, we understood that we wouldn’t just be supplying products to customers, we’d actually be supplying sustainability right beside those products.”

 

The company uses objective traditional sustainability metrics — such as measuring greenhouse gas emissions, water usage and energy consumption — along with initiatives tied more closely to product development and marketing.

 

Welsh said that the company's Eco+ products are products than have a lower carbon footprint that a competing product on the market, while having at least the same functionality. The company’s goal is to have 80 percent of new products in its pipeline be Eco+ by 2015, as well as 50 percent in total sales.

Les opérations de nettoyage visent également à pomper les nappes pétrolières ou huileuses qui se sont répandues dans la mer: environ 30.000 litres sur les quelques 400.000 litres de pétrole qui pourraient avoir été déversés l'ont été.

Les autorités nettoient aussi la colline surplombant la plage de Refugio, où se trouvait l'oléoduc qui a fui, pour que le pétrole qui a imprégné le sol ne se déverse pas sur l'autoroute ou encore vers la mer.

Plains All American Pipeline doit de son côté pomper le pétrole qui reste à l'intérieur du tuyau. Patrick Hodgins, l'un des responsables de la société, estime que l'enquête pour savoir ce qui s'est passé sur cet oléoduc de 60 cm qui date de 1987, va durer des mois.

Transition énergétique : les Etats-Unis misent sur les réseaux intelligents

Transition énergétique : les Etats-Unis misent sur les réseaux intelligents | Développement durable et efficacité énergétique | Scoop.it
Alors qu'en France le débat sur la transition énergétique vers les énergies renouvelables n'est toujours pas terminé, les Etats-Unis investissent massivement dans le solaire et l'éolien. Comment les "réseaux intelligents" à base d'énergies renouvelables sont-ils en voie de transformer radicalement la donne énergétique américaine ? 

Via Hubert MESSMER @Zehub on Twitter
Stephane Bilodeau's insight:
Un plan fédéral ambitieuxDepuis 2009, le Congrès américain a voté  des aides et incitations aux particuliers et aux entreprises pour la production d'énergies renouvelables, et ce, de façon massive. 18 milliards ont donc été investis par l'Etat fédéral, et depuis lors, la part de l'éolien et du solaire photovoltaïque ne cesse d'augmenter dans la production énergétique américaine. La production photovoltaïque a atteint 12,8 TWh aux Etats-Unis en 2012, soit une augmentation de plus de 140 % par rapport à l’année précédente, quand l'éolien est devenu numéro un de cette filière dans le monde, fin 2014, avec une capacité de 65 879 MW, l’équivalent des besoins d’électricité de plus de 15 millions de foyers américains, soit plus de la moitié de toute la production électrique française (128 MW). Réseaux intelligents énergétiques "maillés"Le développement des énergies renouvelables ne peut pas se faire de la même manière qu'avec les énergies fossiles ou le nucléaires pour une raison simple, qui est celle de l'intermittence. Le soleil est invisible la nuit, et le vent n'est pas permanent.  Le principe des smart-grids est donc incontournable pour produire et distribuer ces énergies intermittentes sans coupure pour l'usager. Les réseaux de distribution électrique intelligents, transportent donc à la fois de l'électricté et de l'information. Quel est l'objectif ? A partir de capteurs, d'enregistrements en temps réel de la consommation, sur des "réseaux maillés", l'électricité produite (le plus localement possible pour éviter les pertes sur de grandes distances) est répartie en fonction des besoins et de l'état de la production, du stockage de l'énergie. L'idée principale est de parvenir à une répartition optimale, s'adaptant en permanence à l'offre et à la demande sur le réseau.

Simon BdR's curator insight, May 20, 5:07 AM

Les réseaux intelligents vont en effet permettre d'intégrer massivement les énergies renouvelables dans le mix énergétique. Il est important d'investir dans ce domaine, mais pas seulement. Le stockage d'énergie doit également jouer son rôle dans la transition énergétique, tout comme il est important de revoir la façon dont l'énergie et vendue sur le réseau (effacement) afin d'inciter ceux qui consomment moins et de manière plus intelligente.

What Do Chief Sustainability Officers Actually Do? | Développement durable et efficacité énergétique | Scoop.it
More and more companies have a senior executive in charge of sustainability, but that doesn't make those companies automatically green.

Via Pascal Teboul
Stephane Bilodeau's insight:

"The strategic aspect of a Chief Sustainability Officer is that you have the expectation from the CEO and the CFO to be the voice of not just what's happening next week or next month, but also the view on trends, risks, and opportunities over the mid- to long-term. This influences our business strategies, including the resources we use, the processes we operate and the products we offer. For example, developing a strategic view on whether building codes will be advancing in India, or China, or Brazil, mimicking what's gone on in Western Europe and the United States, helps to frame our opportunities in those regions. Can we influence that trajectory? Where can we lead change, and where should we be responsive?"

New York Is the World's Most Wasteful Megacity, in 3 Charts

New York Is the World's Most Wasteful Megacity, in 3 Charts | Développement durable et efficacité énergétique | Scoop.it

New York, many say, is the greatest city in the world. It also might be the most wasteful.

That's according to a new study published in Proceedings of the National Academy of Sciences. The large research team, led by Christopher A. Kennedy of the University of Toronto, examined how 27 "megacities" (metropolitan areas with more than 10 million people) metabolize resources and create waste. Together these monster cities consume 9.3 percent of the world's electricity and produce 12.6 percent of the world's waste—even though they contain only 6.7 percent of the world's population.

Hidden Costs From Our Dependence on Fossil Fuels | Ira Kalb Blog | HuffPost.com

Hidden Costs From Our Dependence on Fossil Fuels | Ira Kalb Blog | HuffPost.com | Développement durable et efficacité énergétique | Scoop.it

If you have ever visited Santa Barbara, it is absolutely beautiful -- except for the oil rigs visible offshore. In 1969 one of those rigs had a blowout that caused 4.2 million gallons of oil to spill. At the time it was the biggest disaster in U.S. waters. Subsequently, the Exxon Valdez spill off Alaska and the Deepwater Horizon disaster in 2010 put it in third place. It killed an estimated 3,500 sea birds and an incalculable number of marine animals and fouled the undersea vegetation, which in turn caused untold damage to the food chain for many years.

Just last week, on May 19, a pipeline rupture caused over 100,000 gallons to spill into Santa Barbara waters. The channel where the spill occurred is where warm water from the south mixes with cold water from the north, creating one of most bio-diverse habitats in the world, with over 800 species of sea creatures, from crabs and snails to sea lions and otters, and a forest of kelp and other undersea plants; it's also a place through which 19,000 gray whales migrate this time each year.

As if the ecological damage and fouling of beaches frequented by visitors on Memorial Day weekend were not enough, prices at the pump are causing more pain -- especially in California, which is paying more for gas than other part of the country.

It is estimated that 80 to 85 percent of the energy consumed in the U.S. is from fossil fuels. One of the main reasons given for continuing to use this energy source is that it is much less expensive than alternatives. The true cost, however, depends on what you include in the calculation.

 

According to the Union of Concerned Scientists, there are so many costs not figured in the bills we pay for energy.The following includes just some of them:

A massive number of bids are submitted in a utility procurement assessing the value of energy storage.
Stephane Bilodeau's insight:

California’s 1.3-gigawatt energy storage mandate is bringing a lot of would-be grid battery project developers out of the woodwork. But there won’t be nearly enough room for everyone who wants a piece of this market.

 

The latest proof of this comes from Pacific Gas & Electric, the Northern California utility that’s seeking about 74 megawatts of storage projects to meet its 2016 procurement target under state law AB 2514. Last week, PG&E quietly let slip that it had winnowed down an initial queue of more than 5,000 megawatts' worth of applications to come up with a short list of finalists.

Energy consultancy Enovation Partners published this news last week, and PG&E spokesperson Paul Moreno confirmed the details with us this week. The utility isn’t disclosing any information about the proposals remaining on its short list, and expects to make its final choices known in a December filing, he said.

Norway to pull $900bn oil fund out of coal | The Local | Développement durable et efficacité énergétique | Scoop.it

Norway’s parliament has unanimously agreed that the country’s $900bn oil fund should radically reduce its investments in coal producers and coal-burning utilities to help limit climate change.

 

The agreement,  reached at a meeting of the Norwegian parliament’s finance committee on Wednesday evening, will require Norges Bank Investment Management (NBIM), which manages the fund, to sell shares in all companies in its portfolio which generate more than 30 percent of their revenues or 30 percent of their power production from coal.

According to Norwegian Finance Minister Siv Jensen, the ban could apply to as many as 75 companies in which the fund has invested some 35 billion kroner ($4.5 billion). Companies sitting above the threshold include power companies RWE, SSE and Duke Energy.  "Investing in coal companies poses both a climate risk and a future economic risk," the seven parties said in a statement announcing the move.  "This is a great victory for the climate," said Torstein Svedt Solberg from Norway's Labour Party, who acted as the rapporteur for the negotiations. "Coal is in class of its own and is the source responsible for the largest emissions of greenhouse gases."

L’Organisation mondiale de la santé (OMS) met plus que jamais l’accent sur les liens entre santé et environnement, tant pour ce qui est des effets de la pollution de l’air que ceux liés au changement climatique. Si les deux phénomènes diffèrent, avec le paradoxe que le réchauffement peut faire diminuer les émissions polluantes liées au chauffage, ils sont tous deux délétères pour la santé humaine. A l’occasion de sa 68e réunion annuelle, les représentants des 194 Etats membres de l’OMS devraient adopter par consensus, vendredi 22 mai, un projet de résolution intitulé « Santé et environnement : agir face aux conséquences sanitaires de la pollution de l’air ».

Via Hubert MESSMER @Zehub on Twitter

A présent, il faudrait montrer un visage humain ».

Rappelant la déclaration du secrétaire général des Nations unies, Ban Ki-moon, selon laquelle « il n’y a pas de plan B.

China's Big Bet: The World’s Future Depends on China’s Energy Use | Sharon Burke | Slate.com

China's Big Bet: The World’s Future Depends on China’s Energy Use | Sharon Burke | Slate.com | Développement durable et efficacité énergétique | Scoop.it

At a recent Houston conference, a senior Chinese official touted what he described as “a new system of power in China and the world.” And while Zhiwei Wang was referring to electricity rather than geopolitics, he may as well have been talking about both. China’s rise is closely linked to the country’s energy security, and the rest of the world’s energy security is increasingly linked to China’s rise.

For the United States, the implications go beyond energy. China’s arrival as the world’s largest energy consumer may well help redraw the geostrategic map.


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

To begin to parse the potential consequences of this “new system,” it’s important to understand why China has become such an important global energy player in the first place. Ultimately, it’s because of the tyranny of scale: That big population of 1.3 billion requires big economic growth. The results are big, too: While the high growth rates of the last two decades have not benefited the Chinese population evenly, they have lifted an astonishing 600 million people out of poverty.

 

All of that growth required energy, and, indeed, China’s energy demand has increased more than 500 percent since 1980. China is now the world’s largest energy consumer and, as of last year, the world’s largest net importer of oil. (The United States overall still consumes three times as much oil per capita, but with the new oil boom, we are meeting more of our own needs domestically.)

Massive Antarctic Ice Shelf Will Disappear Completely In A Few Years, According To NASA | Natasha Geiling | Think Progress

Massive Antarctic Ice Shelf Will Disappear Completely In A Few Years, According To NASA | Natasha Geiling | Think Progress | Développement durable et efficacité énergétique | Scoop.it

An Antarctic ice shelf roughly half the size of Rhode Island will disintegrate completely within the next few years, according to a NASA study released Thursday.

In 2002, two-thirds of the Larsen B Ice Shelf — which had been intact for more than 10,000 years — broke up in less than six weeks. The remaining portion of the ice shelf covers about 625 square miles along the Antarctic Peninsula, extending toward the southern tip of South America.

Using data collected from airborne surveys and radar, a team led by Ala Khazendar at NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California, found that the remaining portion of Larsen B is weakening very quickly, which is causing the shelf to become increasingly fragmented. Two of its tributary glaciers are also flowing faster and thinning more rapidly, according to NASA.


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

“These are warning signs that the remnant is disintegrating,” Khazendar saidin a statement to NASA. “Although it’s fascinating scientifically to have a front-row seat to watch the ice shelf becoming unstable and breaking up, it’s bad news for our planet. This ice shelf has existed for at least 10,000 years, and soon it will be gone.”

California is drilling for water that fell to Earth 20,000 years ago | Tom Knudson | Mother Jones | Développement durable et efficacité énergétique | Scoop.it

By now, the impacts of California's unchecked groundwater pumping are well-known: the dropping water levels, dried-up wells and slowly sinking farmland in parts of the Central Valley.

But another consequence gets less attention, one measured not by acre-feet or gallons-per-minute but the long march of time.

As California farms and cities drill deeper for groundwater in an era of drought and climate change, they no longer are tapping reserves that percolated into the soil over recent centuries. They are pumping water that fell to Earth during a much wetter climatic regime—the ice age.

Such water is not just old. It's prehistoric. It is older than the earliest pyramids on the Nile, older than the world's oldest tree, the bristlecone pine. It was swirling down rivers and streams 15,000 to 20,000 years ago when humans were crossing the Bering Strait from Asia.

Over the past century, US groundwater has been depleted by nearly 1,000 cubic kilometers—about twice the volume of Lake Erie.

A new article by Konikow in the journal Groundwaterestimates that nearly 1,000 cubic kilometers—about twice the volume of Lake Erie—was depleted across the United States from 1900 to 2008. That's enough to contribute to rising sea levels, along with melting glaciers and polar ice.
