Right now coal accounts for 39% of all the world's generated electricity, with gas coming in second but still trailing behind at 22%. King coal is dying though, as ZME Science reported earlier. In less than 15 years, the International Energy Agency estimates renewable energy will become the dominant energy source in the world. Moreover, these estimates are conservative since the report assumes many coal plants will still be online in 2030, which is unlikely.
Marine biologists study microbes in the waters above natural oil seeps in the Gulf of Mexico stumbled upon something unexpected. They found phytoplankton, tiny organisms that comprise the bottom of the marine food chain, thrive in waters with low concentration oil. In some cases, the population is double that a couple miles off the oil seep sites.
Water pollution is a big issue, and so far there isn't one single system capable of reliably filtering toxic heavy metals. These are either too small, or selectively filter certain metals when polluted water often contains a mix. Researchers at ETH Zurich claim they've hit a breakthrough. Using cheap, readily available materials they designed a filter that can retain over 99% concentration of mercury, gold cyanide or toxic potassium, to name a few. It can also absorb radioactive waste and help recycle gold.
Before WWII, there weren't that many plastics around. Today, we use so much that we could literally plaster the planet in one giant clingfilm. A paper published in the journal Anthropocene reviews the state of plastic production, use and pollution and concludes that no place on Earth has been spared.
Authorities sealed off the area and are now investigating possible environmental pollution from the underground lake of acrid oil.
When the researchers analyzed some of the most cited contrarian climate change papers -- by other scientists or in the media -- they found these were riddled with methodological errors and not one one of them stood to scrutiny.
A study from Emory University looking into prairie voles' consoling behaviors provides new evidence in support of animal empathy. The tests had pairs of voles isolated from each other, one being exposed to mild electric shocks, to study how the rodents react to a distressed mate.
The Namib Desert Beetle lives in one of the most inhospitable and driest places on Earth, in the southwest coast of Africa. The beetle, however, employs a nifty trick: it can virtually make water out of thin air, thanks to its body whose geometry collects water droplets and directs them right into the insect's mouth. Now, engineers have adapted this design to keep ice bridges from forming and keep critical aircraft components freeze-free.
According to a report published by Amnesty International, half of the world's Cobalt, an important element used in lithium batteries, is mined in the Democratic Republic of Congo (DRC) by child miners. Most handheld electronics today (like smartphones or tablets) incorporate lithium-ion batteries (LIBs) based on lithium cobalt oxide (LiCoO2), which offers high energy density.
The Chinese government seems determined to phase out coal from their economy.
Plastic bags, bottle caps and plastic fibres are among the myriad of micro plastic debris that wash out into the Pacific Ocean. These get ingested by the marine life like fish, mammals and birds which are dying from choking, intestinal blockage and starvation. Moreover, some are toxic pollutants that are absorbed, transported, and consumed in the food chain eventually reaching humans. The most effective way to contain microplastics is to raise floating nets around Asia's coats, not around the Great Pacific Garbage patch, researchers reckon.
The global fish stocks are depleting at alarming rates, much faster than reported by the UN, a study found.
China just announced the deployment of the world's largest electric buses - in the city of Shenzen.
After they studied how much man-made heat got sucked by the world's oceans in the past 150 years, researchers found the heat content doubled since 1997. In other words, the oceans absorbed just as much heat in the past 20 years or so as they did in the prior 130 years. There's more bad news. The rate at which oceans soaked the heat rose sharply since the 2000s and hasn't faltered since. This can only mean a re-doubling that comes with unforeseeable consequences in the coming decades.
According to a study conducted by NASA in 2013, using nuclear energy instead of coal saved almost 2 million lives since 1979 - by allowing us to not use coal.
MIT scientists have developed a material that can absorb solar energy, stores and release it on demand to produce heat. Made from a film of polymer, the material could be used to used to tailor cold climate garments that charge up during the day and keep you pleasantly warm in the evening.
Denmark's wind turbines set a spectacular world record as they alone generated over 42 percent of domestic electricity use in 2015 - the most ever done by any country.
The city of London is sued for polluting too much – about 40 times more than it should under EU (European Union) regulation. At 7AM local time last Friday, London officially breached the pollution limits set by the European Union for the entirety of 2016. It’s the fifth year in a row London has grossly surpassed […]
The slump in oil prices coincides with the highest investment in renewables ever: $329.3 billion just in 2015.
Price is one of the main road blocks in the way of getting an electric car - changing your gas guzzler for a cleaner car can come at quite a cost.
Indiana University scientists have built a highly efficient bio-material that can serve as a catalyst for hydrogen production. This material takes us halfway towards the long sought-after "holy grail" of splitting water to make hydrogen and oxygen for fueling cheap and efficient cars that run on water.
Agriculture is a very risky line of work since its inevitable once in a while extreme weather will take a huge toll on the crop yields. This is common knowledge, but the quantitative impact of droughts and heat waves has only recently been investigated in great detail. A paper published in Nature by researchers at University of British Columbia found droughts cut a country’s total crop yield by 10 percent, and heat waves by 9 percent. Floods and cold spells oddly did not affect crop production in a significant way. These effects vary from country to country and another surprising finding is that crops in developed countries suffer up to twice as many losses than those in developing countries.
According to the United Nations, 20 to 40 percent of fresh food is thrown away by farmers because they don't look as appetizing as they should to sell. Besides looking a bit crooked, twisted or shrugged, these fruits and vegetables are perfectly edible and taste no different than the perfectly shaped ones you're always on the lookout for in the supermarket.
The very hot winter of 2015 is having some unexpected consequences: squirrels are getting fat. The winter season for overindulgence has come and passed, but for these little critters in North America and Europe, it left behind a big mark. The mild climate of this winter meant that trees had lots of seeds and nuts, […]
Where do we find the space for trees in our cities with all the buildings already vying for the limited space available? Dutch collective Mothership's answer is waterways. The group plans to install the "Dobberend Bos" (Bobbing Forest) in Rotterdam's Rijnhaven harbor next spring.
The government has declared a state of emergency in the most affected areas while scientists are trying to figure out why so many babies are born with this often lethal condition.
The indispensable chemical mixture that allows the industry to fracture rock and release the gas trapped inside looks almost like a black box. More than 1,000 chemicals are used in the fracking fluid, but a paper published in the Journal of Exposure Science and Environmental Epidemiology found toxicity information was lacking for 76% of them. In other words, these could be harmless or dangerous. There's no way to know at this point. Concerning the rest -- about 240 substances -- the researchers found evidence that suggests reproductive toxicity for 103 (43%), developmental toxicity for 95 (40%), and both for 41 (17%).
Archaeologists working at NOAA made a surprising discovery - they found the remains of a century-and-a-half old whaling ship
A new study from Stanford University found that the world could realistically go 100% renewable in a few decades, using only wind, water, and sunlight (WWS). Right now, we’re still a long way to go. Less than 5% of the planet’s energy demands are satisfied with renewables, but things are improving fast. “As of the end of […]
It's official - humanity has changed the Earth so much that we've basically created a new geological era, one that scientists call the Anthropocene.
As we mentioned before, the largest gas leak in history is unfolding in California, but oddly enough, few people seem to care enough or understand the magnitude of what's happening.
Columbia University researchers have successfully identified the cellular network that allows mice to remember which environments are safe and which are dangerous. The study also looks into what happens when these neurons are tampered with, offering insight into how conditions such as PTDS, panic attacks and anxiety disorders can be treated.
Throughout our hunter-forager days, humans have developed a subconscious urge to over-eat and became less and less psychologically equipped to avoid obesity, especially during the winter months, a University of Exeter study recently found.
The Chinese capital is notoriously polluted and frequently plagued by smog, a noxious gas mixture made of nitrogen oxides, sulfur oxides, ozone, smoke or particulates. While 2015 saw cleaner air in Beijing than the year before, the current state of affairs lack in resolution, as echoed by concerned Beijing residents. With a lot of planning, hard work and a bit of luck, this situation might change for the far better as the Beijing Environmental Monitoring Center announced it plans to cut airborne pollution by more than 200% by 2030.
Winter's here with all its holiday cheer and if you're like me, way too much food. Also something that winter's very good at is making the great outdoors cold and the small indoors even colder. But worry not because Marco Zagaria, a student at Rome's Academy of Fine Arts, promises he can make your home warm and comfortable for a measly 10 cents a room each day, without using any electricity.
A GreenTechMedia analysis forecasts that energy storage systems, like large density batteries, will become a lot cheaper in the coming years. According to the report, the cost of installing an energy storage system will drop by some 41% by 2020. Energy storage is tightly linked with renewable energy generation, driving a lower cost overall for clean energy.
These aren't Christmas lights, but the actual neural activity of Caenorhabditis Elegans, a parasitic nematode. The brain imaging was done by researchers at Princeton University, and no worm had to be cut open. Instead, the researchers used a special protein which fluoresces in response to calcium.
Everybody has to eat, but for all their efforts farmers can easily lose a year's worth of crops due to a dry season or some other freak weather event.
Scientists are pushing the non-publication of geographical data of new species in order to protect them from poachers.
The British government has announced that they will create a marine reserve almost as big as the UK in the waters of Ascension Island in the South Atlantic between Brazil and Africa. It’s good news, but it’s still a far cry from what scientists and conservationists asked for to preserve species and expand fish stocks. The […]
Research has confirmed that Henry Mountains of southern Utah are home to a rare, genetically pure bison herd. This is the only genetically pure bison herd we know of, after all other surviving members of the species were crossbred with cattle. The team that confirmed their genetic heritage included Utah State University scientists. Dr. Johan du Toit, […]
In what is likely the most underrated disaster of the year, a massive natural gas leak is taking place in Aliso Canyon, California, about 25 miles north of Los Angeles. The leak has been spewing about 62 million standard cubic feet of methane per day into the atmosphere after a well was mysteriously damaged on October 23 […]
The two largest cities in Italy have taken drastic measures as pollution levels continue to rise and smog builds up.
Ski slopes (runs) are an environmental bane, as more and more studies are beginning to show. Even after 40 years of abandonment, the environment still fails to recover on the graded slopes.
There’s almost no need to say it again – it’s been an exceptionally warm December, and an exceptionally warm year. In fact, it’s been the hottest year on record, with 7 of 11 months so far breaking the record. Things aren’t very different in the capital of the US, where temperatures have exceeded 50 degrees […]
A month ago, millions of gallons of toxic mining waste burst into the environment following a dam break in the Brazilian state of Minas Gerais. Since then, the sludge has left behind a 500 mile (800 km) trail of polluted rivers and banks, ultimately reaching the Atlantic Ocean and marking Brazil’s worst environmental disaster in […]
In a world class display of hypocrisy, after opening up the world’s largest marine sanctuary and vowing to reduce fossil fuel subsidies, the New Zealand government has opened up a marine reserve of the world’s rarest dolphin for oil exploration – most significantly, seismic surveys. The Maui dolphin is the world’s rarest, with under 60 […]
Lions are listed under the Endangered Species Act, five months after a famous lion was lured away from a protected national park in Zimbabwe and killed by an American dentist. The decision announced by the Fish and Wildlife Service (FWS) is aimed to help with lion conversation as it will make it increasingly difficult for hunters to bring back trophies from Africa. While it doesn't ban the import of trophies (which would've been ideal), the new ruling has been met with great enthusiasm by environmental groups around the world.
It's the bigger or charismatic of animals that get targeted by human hunters. These give off more meat, more pelt and make for better trophies. The effects of over-hunting and poaching are well documented. Most markedly, this results in extinction and ecosystem destabilization. A new study, however, adds a new frighting dimension to hunting: climate change acceleration through loss of carbon storage.
Elephant social structure is deeply matriarchal, meaning their groups look to older females for leadership. A new study looks into how, even with poaching picking their matriarchs off one by one, elephant social structures unexpectedly managed to survive.
