The wealthiest man in the world, Bill Gates, will announce on Monday a massive private-government partnership for a new clean energy research fund. This is reportedly the biggest research and development fund for clean energy ever, which will funnel billions to support innovation in this section. The precise details of the multi-billion partnership will be revealed once with the opening of the United Nations conference on climate change in Paris.
If you still think wind and solar energy can't possibly work because they're too expensive, you're trapped in time. As the technology improves and manufacturing of scale comes into full force we're seeing prices per unit of energy dwindling. Elsewhere, regulations like price on carbon is making fossil fuel energy more expensive. According to the Bloomberg New Energy finance, on-shore wind energy has once again dropped in price and is competitive with conventional coal or gas fired energy. In some parts of the world, like Germany or UK, on-shore wind is up to 30% cheaper than fossil fuel energy. Apparently, we're running out of reasons not to ditch fossil fuels in favor of renewable energy.
Couple of weeks ago, Volkswagen admitted it had cheated US tests to make its diesel cars seem more green than they actually were. Later, ZME Science reported companies like Renault, Nissan, Hyundai, Citroen, Fiat or Volvo were also cheating. Then, independent lab tests showed some Samsung TVs were rigged to use less energy during official testing conditions than they do during real-world use. Now, famous British inventor James Dyson is accusing German companies Bosch and Siemens of doing the same thing, gaming energy ratings for their vacuum cleaners.
Solar energy could be turned up a notch not by some exotic material or chip, but surprisingly by viruses. A team at MIT published a paper demonstrating how a genetically modified virus was used in a quantum system to transfer energy at double the speed and over a greater distance than even the best solar cells.
Solar-aided power plants could mean less CO2 for a fraction of the costs of solar-only, paving the way for a full-renewable power supply.
With all its cons and pros, at this time, nuclear power remains our best shot at decarbonizing the planet and ridding the world of its dependence of fossil fuel. During the 60s and 70s, many of the world's governments, including France, the US or the USSR embarked on ambitious projects to electrify their nations using nuclear power. Accidents like those at Three Mile Island (1979), Chernobyl (1986) or Fukushima (2011) served to halt this rapid pace of deployment and even shift policy back to massive fossil fuel deployment. Anti-nuclear power public sentiment did little to help, of course. Considering that the combined power of solar, wind and hydropower can't yet rid us of pesky oil and gas, wouldn't it be better if we embraced nuclear nevertheless, with all its shortcoming (many of which have been addressed by modern technology)? Two researchers wondered if the world was to hypothetically shift in high nuclear gear, how long would it take to completely shelve fossil. Their analysis showed if we built nuclear power plants at the rate Sweden had between 1960-1990, this target would be reached within 25 years.
Fahrenheit may be the best way to measure temperature after all. Why? Because most of us only care about air temperature, not water temperature.
Solar power is one of the most efficient yet clean sources of energy we have access to. There are no increased fuel costs or dependencies, no ties to pollutants, and it’s both reliable and affordable. Of course, in order to harness solar power you need access to specific technology. This tech relies on either small-scale […]
Since ancient times, people living in hot climates learned if they paint their rooftops white, then their quarters would stay cooler during the scorching heat. In an attempt to curve energy consumed on air conditioning, which accounts for 15% of all electricity consumed in the US, scientists have devised a multi-layered surface that acts in […]
Some of us like to think that the energy needs of the future will be supplied by clean and renewable energy sources, but a recent report released by the Manhattan Institute for Policy Research leads us through the mist and shows a cruel reality: coal, the dominant energy source in the world today, will continue […]
A new milestone study found that mitochondria – the energy factories in animal and plant cells – were initially very similar to parasitic bacteria some two billion years ago, and only later did they become energy sources. Very little is known about the origins of mitochondria, but by probing the genomes of bacteria closely related to […]
Given the shale boom, the United States has now become the world’s leading natural gas producer. Because it only releases 50% as much emissions for the same equivalent amount of energy produced by oil or coal, many have herald it as a cleaner source of fossil energy, whose widespread introduction might help mitigate global warming. […]
The world is currently on a downward spiral, risking reaching a point of no return where global warming can no longer be reversed – not in due time at least. We’re already 50ppm of CO2 (parts per million) over the 350ppm average atmospheric CO2 concentration, considered by leading experts the carbon stabilizing threshold. It’s increasingly […]
Some people become in love with physics because they’re secretly in love with the truth. Physics never lies, if you care to think in absolute terms, so there must be a great deal of comfort. The reason modern civilization works they it does today is because of our faith in physics and other sciences. If […]
The Simpsons Movie’s plot starts off with Homer adopting a messy piglet he names “Spider Pig”. The pig, helped a great deal by Homer, made enough waste to fill a silo in just two days, so how does Homer decide to solve this problem? Naturally, being Homer (doh!), he throws away the silo into the […]
Professor Terry Dawson of the University of New South Wales and colleagues found that kangaroos use their tail as an extra leg when walking, actively participating with energy in the process, instead of using it like a strut as some literature would had us believe. The findings might prove to be important for robotics applications. Hoppity hop […]
The falling cost of renewable energy shouldn’t surprise anyone by now – all we’re waiting for is the tipping point where some type of renewable energy becomes more cost effective than conventional energy – but what if we’ve already reached that point? Portugal is one of Europe’s (and the world’s) leading countries in terms of […]
The humongous grey whale and the skipjack tuna, though of contradicting sizes, both employ similar propelling mechanisms through water. Pound per pound, however, which of the two animals is most energy efficient? Engineers at Northwestern University have developed a new metric for analyzing such problems and found that the two marine animals are almost just as […]
When you think of timber technology, the first things that come to mind may be constructing homes, wooden tools and, of course, paper. Oregon State University researchers have found, however, that trees could be employed in a process that produces building blocks for supercapacitors – high tech energy storage devices that are considered paramount for the future’s […]
In the future, your saliva might power key microelectronics. Researchers at Penn State have devised a micro-sized microbial fuel cells that is power by the organic materials and bacteria present in saliva. The power generated by the tiny fuel cell is very small, though, so don’t expect charging your phone by spitting in it any […]
One of the biggest arguments against renewable energy deployment on the truly massive scale is their unreliability. Justly so, wind doesn’t always blow at desired velocities and the sun fluctuates in sunshine throughout the day. With this in mind, if you don’t have a back-up storage medium, intermittent renewables will always be an alternative – […]
Using a range of cheap materials arranged in a specific manner, researchers at Duke University have demonstrated a device that captures microwave signals, such as those relayed by WiFi or even satellites high up above in Earth’s orbit, an converts this free, lost energy into electrical current. The harvesting and conversion efficiency of the device […]
There’s been a lot of praise and finger pointing alike around the hydrogen economy, and whether or not fuel cells can be scaled to reasonable levels i.e. becoming actually useful. There are a lot of problems with fuel cells in terms of their economy. Fuel cells are some of the most efficient energy converters current […]
Hybrid nuclear plants, working in conjunction with geothermal, shale oil, or hydrogen production could help slow climate change, and provide more cheap energy – when used . More than the sum of its parts Many efforts have tried to smooth the transition of renewable energy and fill in its gaps, and a rather viable, yet […]
Jellyfish are really impressive creatures, for all their simplicity; now, a new research has shown that the elastic body allows moon jellyfish to travel extra distance at no energy cost. The sockeye salmon is a sleek, muscular torpedo which rams up waterfalls. The jellyfish is a blob, drifting on aimlessly in the oceans. Obviously, the […]
Even in these modern times, steam condensation is one of the main drivers of electricity production and clean water: It is part of the power cycle that drives 85 percent of all electricity-generating plants and about half of all desalination plants globally, according to the United Nations and International Energy Agency. So improving the efficiency […]
The Hawthorne effect (commonly referred to as the observer effect) is a form of reactivity whereby subjects improve or modify an aspect of their behavior, which is being experimentally measured, in response to the fact that they know that they are being studied. Essentially, when most people know or feel their actions are monitored, they […]
Besides being a great family time activity and an awesome display of art for some who have way too much time on their hands, dominos are also a great mathematics exercise. Although most dominos are the same size, it’s well documented that the first domino piece can topple a second larger domino piece, which in […]
In today’s fast evolving world of tech, miniaturization is crucial. In most portable consumer electronics goods, like smartphones or tablets, the typical lithium-ion battery takes up quite its share of space, impending further sensible miniaturization of design. A new technique developed by scientists at Rice University might, however, render battery volume to a minimum, following the advent of a […]
Last week, the U.S. Air Force released a report in which it outlines its technological and energy plans for the forthcoming 15 years. Among others, the Air Force means to deploy a space-based solar power station, which would serve energy wirelessly to both Earth and space satellites, as well as a new generation of spacecraft […]
We at ZME Science love futuristic designs, but above all we love innovative energy efficient solutions. The latest avantgarde lighting set-up from Philips would fit better in an art gallery than in a home, however what it lacks in practicability, it more than makes up in beauty, and moreover in principle – that energy is […]
A new massive research from SMU’s Geothermal Laboratory, funded by a grant from Google.org has documented significant geothermal resources across the US (especially in the West), a resource that has the potential, with today’s technology, to produce over three million megawatts of green power – that’s 10 times more than coal plants currently produce. Sophisticated […]
While a dog’s psychological value to its owner is very much attested, helping cure loneliness and such, a recent study published in the Journal of Physical Activity and Health, finds that people who own and walk a dog are 34 percent more likely to meet federal benchmarks for physical activity. “Walking is the most accessible […]
Yes, you’ve read that right. There are over 50 billion planets in our galaxy alone, according to the Kepler telescope, scientists now estimate that not only there are over 500 bilion planets in the galaxy, but that there are over 500 million life-cable planets out there as well. These numbers obviously come from Nasa’s own […]
Parts of the car’s bodywork could double up as it’s batter in a not so far away future; at least that’s what the people involved in the 3.4 million project believe. They are working on a prototype that can store and discharge electrical energy; the material is also light and very hard. Ultimately, this will […]
Boy I’ve gotta tell you, my jaw really dropped when I heard this one. There are actual lakes, on the bottom of oceans, especially in the Gulf of Mexico region; they’ve got their own shores and all. The brine water of these lakes actually hosts unique wildlife, creating an absolutely amazing environment. The fact that […]
Biofuels seems to be the word on everybody’s lips today, and for good reason. It’s necessary that people understand the benefits and importance of this development, as it could be a huge step in protecting our resources and planet. Fortunately, some breakthroughs have been made which give us confidence that things are moving (slowly, but […]
It’s hard to say that during last year’s G8 summit the “world leaders” made promises and predictions that were just words for the voters without feeling ridiculous; I’m not one to fall for fine words that sounds identical to what you want to hear, but I was expecting at least few of those I heard […]
If you were to be optimistic, where do you think mankind would get most of its energy a century from now? Most would say from renewable sources. In fact, this project has been going on for a few years now. But just as any project needs, this one has an experiment which so far has […]
Photo by jago In a study conducted by researchers at Virginia Polytechnic Institute and State University that claimed a different perspective, it was published that it takes between 3,000 gallons and 6,000 gallons of water to power a 60-watt incandescent bulb for about 12 hours per day in a year. As it turns out, size […]
Green fuels are a really hot topic, with every single day bringing a new (claimed) discovery or breakthrough, but many of them are just minor improvements. Still, every once in a while you hear about something that sounds really promising (like green gasoline). Now it seems that chemists are describing development of a “revolutionary” process […]
Researchers are searching everyday for options which could bring an ending to the energy issue or at least delay it for an undefinite time and bacteria researching has developed a lot so it would only seem sensible to bring those two together. The point would be well to obtain a bacteria which generates electricity. Researchers […]
The need to find out energy sources and the development of genetic and microbiology make it likely to find out bacteria or microbes which could be very useful. In this case the bacteria should be able to eat sugar or sludge and it must be team player or electrochemically active. Surviving without oxygen would be […]
