Renewable energy surges to record levels around the world

BBC News reports: New solar, wind and hydropower sources were added in 2015 at the fastest rate the world has yet seen, a study says.

Investments in renewables during the year were more than double the amount spent on new coal and gas-fired power plants, the Renewables Global Status Report found.

For the first time, emerging economies spent more than the rich on renewable power and fuels.

Over 8 million people are now working in renewable energy worldwide.

For a number of years, the global spend on renewables has been increasing and 2015 saw that arrive at a new peak according to the report. [Continue reading…]

Oil company records from 1960s reveal patents to reduce CO2 emissions in cars

The Guardian reports: The forerunners of ExxonMobil patented technologies for electric cars and low emissions vehicles as early as 1963 – even as the oil industry lobby tried to squash government funding for such research, according to a trove of newly discovered records.

Patent records reveal oil companies actively pursued research into technologies to cut carbon dioxide emissions that cause climate change from the 1960s – including early versions of the batteries now deployed to power electric cars such as the Tesla.

Scientists for the companies patented technologies to strip carbon dioxide out of exhaust pipes, and improve engine efficiency, as well as fuel cells. They also conducted research into countering the rise in carbon dioxide emissions – including manipulating the weather.

Esso, one of the precursors of ExxonMobil, obtained at least three fuel cell patents in the 1960s and another for a low-polluting vehicle in 1970, according to the records. Other oil companies such as Phillips and Shell also patented technologies for more efficient uses of fuel.

However, the American Petroleum Institute, the main oil lobby, opposed government funding of research into electric cars and low emissions vehicles, telling Congress in 1967: “We take exception to the basic assumption that clean air can be achieved only by finding an alternative to the internal combustion engine.” [Continue reading…]

Portugal runs for four days straight on renewable energy alone

The Guardian reports: Portugal kept its lights on with renewable energy alone for four consecutive days last week in a clean energy milestone revealed by data analysis of national energy network figures.

Electricity consumption in the country was fully covered by solar, wind and hydro power in an extraordinary 107-hour run that lasted from 6.45am on Saturday 7 May until 5.45pm the following Wednesday, the analysis says.

News of the zero emissions landmark comes just days after Germany announced that clean energy had powered almost all its electricity needs on Sunday 15 May, with power prices turning negative at several times in the day – effectively paying consumers to use it.

Oliver Joy, a spokesman for the Wind Europe trade association said: “We are seeing trends like this spread across Europe – last year with Denmark and now in Portugal. The Iberian peninsula is a great resource for renewables and wind energy, not just for the region but for the whole of Europe.”

James Watson, the CEO of SolarPower Europe said: “This is a significant achievement for a European country, but what seems extraordinary today will be commonplace in Europe in just a few years. The energy transition process is gathering momentum and records such as this will continue to be set and broken across Europe.” [Continue reading…]

VW and Shell accused of trying to block EU push for electric cars

The Guardian reports: VW and Shell have been accused of trying to block Europe’s push for electric cars and more efficient cars, by saying biofuels should be at heart of efforts to green the industry instead.

The EU is planning two new fuel efficiency targets for 2025 and 2030 to help meet promises made at the Paris climate summit last December.

But executives from the two industrial giants launched a study on Wednesday night proposing greater use of biofuels, CO2 car labelling, and the EU’s emissions trading system (ETS) instead.

In reality, such a package would involve the end of meaningful new regulatory action on car emissions for more than a decade, EU sources say. But Shell insisted it is not trying to block an EU push for electric cars. [Continue reading…]

China wants to power the world through a global grid

Earth

Adam Minter writes: China’s State Grid Corporation, the world’s biggest power company, is on an impressive buying binge. As Bloomberg News reports, the company is “actively in bidding” for power assets in Australia, hoping to add them to a portfolio of Italian, Brazilian, and Filipino companies. The goal isn’t simply to invest, however. State Grid’s Chairman Liu Zhenya has a plan that he believes will stall global warming, put millions of people to work and bring about world peace by 2050.

The idea is to connect these and other power grids to a global grid that will draw electricity from windmills at the North Pole and vast solar arrays in Africa’s deserts, and then distribute the power to all corners of the world. Among other benefits, according to Liu, the system will produce “a community of common destiny for all mankind with blue skies and green land.”

It’s a crazy idea, of course. And if this so-called Global Energy Interconnection had been proposed by anyone other than the chairman of the world’s wealthiest power company, it wouldn’t deserve much consideration. But the $50 billion in cash generated by State Grid last year gives the company the deep pockets and political standing to put its priorities on the international energy agenda.

Last September, no less than Chinese President Xi Jinping publicly called for talks on establishing a global grid, while leading research organizations — including the Argonne National Laboratory and the Edison Electrical Institute — have participated in conferences looking at what would be needed to establish one. And whether or not it’s ever built, the technologies that underlie Liu’s big idea are already changing how power will be generated and transmitted in coming decades. [Continue reading…]

Surge in renewable energy stalls world greenhouse gas emissions

denmark-wind-power

The Guardian reports: Falling coal use in China and the US and a worldwide shift towards renewable energy have kept greenhouse gas emissions level for a second year running, one of the world’s leading energy analysts has said.

Preliminary data from the International Energy Agency (IEA) showed that carbon dioxide emissions from the energy sector have levelled off at 32.1bn tonnes even as the global economy grew over 3% .

Electricity generated by renewable sources played a critical role, having accounted for around 90% of new electricity generation in 2015. Wind power produced more than half of all new electricity generation, said the IEA. [Continue reading…]

Is nuclear power our energy future — or a dinosaur in a death spiral?

Dave Levitan writes: Nuclear power is dead. Long live nuclear power. Nuclear power is the only way forward. Nuclear power is a red herring. Nuclear power is too dangerous. Nuclear power is the safest power source around. Nuclear is nothing. Nuclear is everything.

It is now generally agreed that the world must rapidly reduce carbon emissions in order to fight off dangerous climate change, but the “how” of that process remains up for debate. And within that debate, nothing seems to produce such starkly opposing viewpoints as nuclear energy. Some experts and advocates argue that carbon-free nuclear power represents the only real hope of keeping the planet’s temperature in check. Others claim that nuclear is risky, unnecessary and far too expensive to make a dent.

The same basic data set — nuclear plants currently in existence, those under construction, the status of new technologies, the history of costs and delays, and a few striking accidents — produces those totally contradictory opinions and predictions. Nuclear power is a Rorschach test: You see what you want to see — a rosy nuclear future or an old-world dinosaur in a slow death spiral — reflecting your own views on the energy present and future. In all likelihood, no one will be proven right or wrong for decades. [Continue reading…]

As Utah coal slumps, solar energy booms

Deseret News reports: The sun is becoming big business in Utah.

Whether it’s in the sun-drenched deserts of Dixie or the sometimes smoggy valleys of northern Utah, more and more homeowners are taking the plunge and betting that solar energy will pay off for them in the future.

The boom has pushed employment in Utah’s solar industry to a point well beyond the job numbers in a more traditional energy sector, Utah’s coal industry.

“Well, I figured I should just own my own power,” said Kerry Zacher, a Centerville man who got his rooftop solar system up and running at the end of September. “I got sick of paying high electric bills.”

He saw immediate benefits.

“September’s bill was roughly 150 dollars,” Zacher said. “October? Nine. Nine dollars.”

Zacher monitors the energy production from his solar panels with an app on his cellphone. He’s already learned that in northern Utah, there are good days as well as occasional very poor days when there’s not enough sunshine to provide for his power needs. On those days he has to rely on power from the grid. On sunny days, though, he often produces excess power that is traded back to the grid. [Continue reading…]

U.S. government agency says it has beaten Elon Musk and Bill Gates to holy grail of battery storage

The Guardian reports: A US government agency says it has attained the “holy grail” of energy – the next-generation system of battery storage, that has has been hotly pursued by the likes of Bill Gates and Elon Musk.

Advanced Research Projects Agency-Energy (Arpa-E) – a branch of the Department of Energy – says it achieved its breakthrough technology in seven years.

Ellen Williams, Arpa-E’s director, said: “I think we have reached some holy grails in batteries – just in the sense of demonstrating that we can create a totally new approach to battery technology, make it work, make it commercially viable, and get it out there to let it do its thing,”

If that’s the case, Arpa-E has come out ahead of Gates and Musk in the multi-billion-dollar race to build the next generation battery for power companies and home storage.

Arpa-E was founded in 2009 under Barack Obama’s economic recovery plan to fund early stage research into the generation and storage of energy.

Such projects, or so-called moonshots, were widely seen as too risky for regular investors, but – if they succeed – could potentially be game-changing. [Continue reading…]

China set to surpass its climate targets as renewables soar

New Scientist reports: China is surging ahead in switching to renewables and away from coal in what its officials say will allow it to surpass its carbon emissions targets.

The country’s solar and wind energy capacity soared last year by 74 and 34 per cent respectively compared with 2014, according to figures issued by China’s National Bureau of Statistics yesterday.

Meanwhile, its consumption of coal – the dirtiest of the fossil fuels – dropped by 3.7 per cent, with imports down by a substantial 30 per cent.

The figures back up claims last month in Hong Kong by Xie Zhenhua, China’s lead negotiator at at the UN climate talks in Paris last December, that the country will “far surpass” its 2020 target to reduce carbon emissions per unit of national wealth (GDP) by 40 to 45 per cent from 2005 levels.

New report shows oil getting dirtier, alternatives cleaner

oil-industry

Union of Concerned Scientists: American motorists are driving more efficient cars than ever, but when they fill up their tanks, the gas they pump into their cars and trucks is 30 percent dirtier to extract and refine than it was just ten years ago, according to an analysis released today by the Union of Concerned Scientists (UCS).

“Even as increased vehicle efficiency has cut global warming tailpipe emissions per mile, the search for tougher-to-extract sources of oil has increased the emissions that come from producing a gallon of gasoline by nearly a third over the past decade,” said Jeremy Martin, senior scientist for the UCS Clean Vehicles Program and lead author of the report.

The UCS report, “Fueling a Clean Transportation Future: Smart Fuel Choices for a Warming World,” is a comprehensive look at the global warming impact of how we fuel our cars and trucks. The report compares oil, biofuels and electricity, and finds a significant and growing gap between oil and other ways to fuel transportation. With more oil coming from depleted wells, tight oil and tar sands the climate impact of oil is rising—emissions from extracting and refining different sources of oil range by a factor of more than five. Electricity and biofuels, in contrast, are already cleaner than oil and have the potential to get even cleaner in years to come. [Continue reading…]

World’s largest concentrated solar plant switches on in the Sahara

CNN reports: Morocco has switched on what will be the world’s largest concentrated solar power plant.

The new site near the city of Ouarzazate — famous as a filming location for Hollywood blockbusters like “Lawrence of Arabia” and “Gladiator” — could produce enough energy to power over one million homes by 2018 and reduce carbon emissions by an estimated 760,000 tons per year, according to the Climate Investment Funds (CIF) finance group.

As His Majesty Mohammed VI of Morocco pressed a button on 4 February 2016, the first phase of the three-part project was set in motion. [Continue reading…]

The world’s most cutting-edge renewable tech is powering rural Africa

Quartz reports: Distributed power — where electricity is generated locally, instead of delivered via complex grid infrastructure — makes lots of sense for Africa. About 600 million Africans don’t have electricity. But sunlight is a widely available resource across most of the continent, making distributed solar power one of the more sensible options for electrification.

Plenty of companies see the potential. This has made parts of Africa a testing ground for cutting-edge solar power. Some countries are developing a whole new type of infrastructure not seen elsewhere in the world: mobile-phone-led, flexible, and controlled by the user rather than big utilities and government.

“We are now seeing the first innovation where the leading technologies are actually being deployed in Africa, not being deployed in the mainstream West,” said Simon Bransfield-Garth, CEO of Azuri Technologies. Azuri is based in Cambridge, UK, and installs rent-to-buy solar systems for homes in Tanzania and several other sub-Saharan states. Power from the panels are paid for by mobile phone or scratchcard. The payments also serve as installments towards owning the system outright. After about 18 months the homeowner has typically paid off the cost of the panels, or can buy them for a very small sum (say, $5). [Continue reading…]

Study: Grid for renewables key to cutting emissions

denmark-wind-power

Climate Central reports: Carbon dioxide emissions from generating electricity could be cut by 78 percent within the next 15 years if the country makes the same Herculean effort to expand solar and wind technology that it did to build the Interstate Highway System.

That’s the conclusion of a National Oceanic and Atmospheric Administration (NOAA) study published Monday in Nature Climate Change, which shows that a new system of transcontinental transmission lines connected to wind and solar farms nationwide is the key to dramatically reducing emissions from the nation’s power plants.

Alexander MacDonald, retired director of NOAA’s Earth System Laboratory and the study’s lead author, said weather occurs on a very large scale and any system capturing sunshine and wind has to be built on a scale to match it. MacDonald said putting such as system in place would be like building a new Interstate Highway System, but the stakes are higher because of climate change.

“There is an opportunity to start very serious (emissions) mitigation right now, that’s what the study says,” MacDonald said. “The idea that wind and solar are too intermittent, or wind and solar are too expensive, or we have to wait for a breakthrough, this study shows that’s not true.” [Continue reading…]

By 2030, renewables will be the world’s primary power source

Climate Progress reports: In November, the International Energy Agency quietly dropped this bombshell projection: “Driven by continued policy support, renewables account for half of additional global generation, overtaking coal around 2030 to become the largest power source.”

In this post, I’ll dive deeper into this rapidly-approaching role reversal for coal and renewables. In Part Two, I’ll explain why the so-called “intermittency” problem for some renewables is basically solved and thus not a barrier to this reversal.

In releasing its World Energy Outlook 2015 last fall, the IEA published this chart of projected electricity generation in 2040: [Continue reading…]

Denmark just broke a world record for wind power — again

denmark-wind-power

Climate Progress reports: One European country can’t seem to stop breaking records when it comes to wind power.

In 2015, Denmark produced almost half of its electricity from wind power, breaking a world record for the most wind production ever recorded — a world record set last year, by Denmark.

The record 42 percent electricity generated from wind represents a three percent increase from the 39 percent it generated in 2014, which at the time broke the world record for the most electricity from wind production by a single country. According to the Danish national grid operator Energinet, this year’s number represents both the highest figure ever and the highest proportion of electricity from wind for any country.

Moreover, for 16 percent of the year, two Western regions in Denmark produced more electricity than the region’s residents consumed, leading to an electricity surplus. While it’s not unusual for wind power production to exceed consumption some of the time, the fact that it happened for such a significant period of time means that Denmark can sell surplus energy to consumers in Norway, Sweden, and Germany. Denmark also imports some hydroelectric power from Norway and solar energy from Germany. [Continue reading…]

Michael Klare: The look of a badly oiled planet

When it comes to news about Saudi Arabia, the execution of an oppositional Shiite cleric, Nimr al-Nimr, has topped the headlines recently — and small wonder.  Aging King Salman bin Abdulaziz al-Saud and his 30-year-old son, Deputy Crown Prince Mohammed bin Salman, the new defense minister who has already involved his country in a classic quagmire war in Yemen, clearly intended that death as a regional provocation.  The new Saudi leadership even refused to return the cleric’s body to his family for burial, but interred it with the many al-Qaeda terror suspects killed at the same time, some beheaded.  After death, in other words, al-Nimr was left in uncomfortable company.  Think of it as the ultimate beyond-the-grave insult.  The provocative message embedded in the announcement of his execution was so obvious that, in Shia Iran, crowds supporting that country’s religious hardliners (with their own hideous execution policies) promptly torched the Saudi embassy in Tehran.  In the following days, as the Saudis broke diplomatic relations with Iran, ended a failing truce in Yemen (promptly bombing a home for the blind and also hitting the Iranian embassy in Sana’a), and rallied Sunni neighboring states to similarly break ties or at least downgrade relations, the whole, roiling region hit the news as war fears rose.

On September 10, 2001, had someone predicted that the oil heartlands of the planet would, within a decade and a half, become a roiling mix of failed states, fierce sectarian religious and ethnic struggles, spreading terror groups, and the first terror “caliphate” in history, if you had suggested that Saudi Arabia, one of the more stable countries on the planet, might someday begin to come unglued, that Libya would essentially collapse, Syria be no more, and Iraq be transformed into a riven tripartite land, you would surely have been laughed out of any room of pundits and experts.  So the recent intensification of such a state of affairs, involving two countries in those heartlands with gigantic energy reserves, is big news indeed — but not perhaps the biggest news in the region.

My own pick might be a story that passed largely unnoticed in our American world.  Sitting atop some of the planet’s great oil reserves and getting 73% of their revenues from oil sales (income that dropped by 23% last year), the Saudi royals just hiked the domestic price of gas at the pump by 40%.  Though it still remains dirt cheap by global standards, that act — which is like charging for salt water in the middle of the ocean — is an indication that something startling is going on.  And note that, in the years to come, that kingdom’s rulers are planning to cut back on similar subsidies for “electricity, water, diesel, and kerosene.”  In other words, the world’s largest oil producer and a country of striking wealth (and foreign reserves) no longer feels comfortable giving away gas to its own population, even though this is part of a bargain it struck long ago for peace in the kingdom.

And the reason for this has little to do with Iran or Syria or Yemen or Iraq or the Islamic State.  The problem is far more basic, as TomDispatch’s resident energy expert Michael Klare points out today.  It’s the price of oil, which in the last 18 months has dropped through the floor.  In a sense, the oil business — with its constellation of giant energy firms, until recently among the most profitable companies in history, and its energy-producing states, until recently riding high — may prove to be the natural-resource equivalent of a failed state, and, as Klare makes clear, the changing economics of oil will transform the political face of the planet.  So keep your eye on Saudi Arabia.  Things there could get ugly indeed.

The oil pricequake
Political turmoil in a time of low energy prices
By Michael T. Klare

As 2015 drew to a close, many in the global energy industry were praying that the price of oil would bounce back from the abyss, restoring the petroleum-centric world of the past half-century.  All evidence, however, points to a continuing depression in oil prices in 2016 — one that may, in fact, stretch into the 2020s and beyond.  Given the centrality of oil (and oil revenues) in the global power equation, this is bound to translate into a profound shakeup in the political order, with petroleum-producing states from Saudi Arabia to Russia losing both prominence and geopolitical clout.

To put things in perspective, it was not so long ago — in June 2014, to be exact — that Brent crude, the global benchmark for oil, was selling at $115 per barrel.  Energy analysts then generally assumed that the price of oil would remain well over $100 deep into the future, and might gradually rise to even more stratospheric levels.  Such predictions inspired the giant energy companies to invest hundreds of billions of dollars in what were then termed “unconventional” reserves: Arctic oil, Canadian tar sands, deep offshore reserves, and dense shale formations. It seemed obvious then that whatever the problems with, and the cost of extracting, such energy reserves, sooner or later handsome profits would be made. It mattered little that the cost of exploiting such reserves might reach $50 or more a barrel.

Scientists move one step closer to turning water into hydrogen fuel, affordably

Christian Science Monitor reports: Scientists have cleared one hurdle on the path to deriving hydrogen fuel from water affordably, a breakthrough that could drastically change the way we power vehicles.

Hydrogen has the potential to fuel incredibly environmentally clean cars. But making that fuel hasn’t been so efficient or economical. Pure hydrogen gas does not occur naturally on Earth, so scientists must devise ways to separate hydrogen from naturally occurring compounds, like H2 O.

Until now, cars that run on water have been out of reach. Electrolysis, the process of breaking H2 O into hydrogen and oxygen gases by passing an electric current through water, and other possible methods have been prohibitively expensive or difficult.

But a team of scientists have come up with a different mechanism to produce hydrogen fuel from water. These researchers have created a biomaterial that catalyzes the splitting of the water elements, which they describe in a paper published in the journal Nature Chemistry. [Continue reading…]
