Wind and solar energy are already nearing parity with energy from fossil fuels in many […]
While scientists have been studying and incrementally increasing solar cell efficiency, we’ve yet to reach nature’s magnitude of solar energy conversion through photosynthesis. Artificial photosynthesis is a goal in alternative energy research, yet the process is extremely difficult to mimic since, in nature, the process involves numerous stages and transformation of matter and energy. Purdue University […]
A crystal known to science for more than a century has only in recent years become recognized for its use in harvesting solar power. Since the first successful usage of perovskite in solar cells in 2009, the advances in the field have grown exponentially over time, making it a potential candidate for revamping the solar […]
Despite the naysayers and constant thorns thrown about by oil lobbyists in the US, Elon Musk‘s Tesla is doing fine, thanks to fantastic leadership, innovative marketing (free charging, battery swapping, Tesla’s own supercharge west coast highway, etc.) and sound engineering. Still, Tesla is an inaccessible brand for most people because of its high-end pricing, but […]
Expect the price of sand to skyrocket! Researchers at University of California, Riverside have devised a coin-sized battery that uses silicone at its anode (negative side), instead of the over-used graphite, that lasts up to three times longer than conventional lithium-ion batteries. The key of the research is the silicon extraction method which uses quartz-rich […]
Renewable energy is clean, getting cheaper by the day and in many respects becoming more efficient thanks to rapid advancements coming from the world’s top-notch labs. It has one major drawback – storage. Before people can find a clever and cost-effective way to store all of that excess energy from wind and solar farms, chances […]
The energy industry simply isn’t keeping up with what Elon Musk wants to do. Musk, chairman of the solar installer SolarCity and founder of electric car company Tesla Motors announced that SolarCity will acquire a solar panel manufacturer and start building factories “an order of magnitude bigger” than those existing today. This comes just a […]
Today, Elon Must, the founder and owner of Tesla Motors announced that they were releasing all the patents they own, for free, for everyone to use. The release of over 200 patents was announced in style, through a blog entry called “All our patents are belong to you“. ” Yesterday, there was a wall of Tesla […]
Electric vehicles started to rise in popularity, but we’re clearly not ready to make such a huge change at once, especially concerning the steady supply of energy that would have to come along with introducing them into massive production and consumption. Scientist Neville Mars has come with a great EV charging station which takes the form […]
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 […]
Researchers at the University of Illinois at Urbana-Champaign report they’ve devised a new type of highly efficient solar cell that is potentially easier to manufacture and cheaper than cells of similar performance. The stacked cell allows photon energy to be garnered from across the whole solar spectrum, and this new design makes use of a […]
The most basic principle of a solar cell is that it works by transferring the energy from an incoming photon (light) to a molecule, which causes one or more electrons to become displaced until an electrical current is formed. That’s the absolute gist of it, only besides electricity, some of the incoming photon energy gets […]
They not only look awesome, but they may actually save a lot of power. Light-absorbing glow-in-the-dark road markings have replaced streetlights on a 500m (0.3 mile) stretch of a highway in the Netherlands; this is just a test, and if everything goes alright, then authorities will implement them over longer and longer sections. The design was […]
Part of an extraordinary venture, researchers at the U.S. Naval Research Laboratory (NRL) report they’ve synthesized hydrocarbon fuel solely from seawater by transforming the CO2 and H2 found in the water. To demonstrate they viability of the fuel, a replica of the legendary WWII P-51 was fitted by an off-the-shelf (OTS) and unmodified two-stroke internal combustion engine […]
An innovative project which addresses both environmental and health concerns has been revealed in Delhi, India. It’s estimated that 2.5 billion people in the world (almost 1 in 3 people) lack proper sanitation – something unimaginable in the developed world. With that thought in mind, a team at the University of Colorado Boulder has designed […]
Floating wind farms may seem like something out of a science fiction novel, but a MIT start-up called Altaeros Energies just unveiled an enormous helium-filled wind turbine which will hover 1,000 feet above ground for 18 months. The turbine, called Altaeros BAT, is a part of a pilot program aimed at demonstrating that airborne wind turbines are feasible. A wind turbine […]
Scientists have made great efforts to discover a material that can be used to both absorb and emit light. A fluke may have suffice, since researchers at Nanyang Technological University (NTU) in Singapore discovered by accident a material that can be used to work as a solar panel, harnessing energy from the sun during the […]
The National Oceanic and Atmospheric Administration (NOAA) said in a statement that California just came off its warmest winter on record. On average there were 48 Fahrenheit (9 Celsius) for December, January and February, making it 4 degrees hotter than the 20th-century average in California. The state is currently facing its most dire drought streak […]
It was only around the mid 1980s that the world finally recognized the dangers posed by the build-up of chlorofluorocarbons (CFCs) in the atmosphere. A big hole in the ozone layer revealed at the time by a team of scientists from the British Antarctic Survey showed what these sort of chemicals withering through the atmosphere could do. […]
Hydraulic fracking has grown to unimaginable hights in the past few years, growing by some 20% a year, and reaching a total market cap of $37 billion today. Recent tumbling prices for natural-gas have slightly detered exploration, but North America at least, which accounted for 87 percent of the fracking market last year, shows no […]
In attempt to mitigate the adverse effects of global warming, one of the key measures considered by policy makers is the introduction of a carbon regulation in hopes that alternative, cleaner energy sources may be supported. In the event of a hypothetical carbon tax, households in the lowest income group would pay as a percent of […]
What nature seems to perform effortlessly with photosynthesis has proven to be an immense hurdle for scientists trying to mimic it with so called artificial leafs. In recent years, important breakthroughs have been made with this scope in mind, yet the artificial leaf is so inefficient at the moment that it’s absolutely not worth pursuing […]
We could exploit energy from deep down in the earth, as a report from a geothermal borehole suggests. The project developed under the name of Icelandic Deep Drilling Project (also known as IDDP), and the shafts have been drilled to almost five kilometers deep, with the purpose of harnessing the heat in the volcanic bedrock […]
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 – […]
One of the most beautiful cities in Europe, Hamburg has embarked on an ambitious plan that aims to promote cycling and walking as the main means of transportation throughout the huge hub. The local administration claims that within 15-20 years the city would have completed its green network that virtually connects any part of the […]
Japanese authorities have approved the construction of a futuristic farming project in Japan’s Fukushima prefecture, in a part of the land which has been radioactively contaminated. It seems the most unlikely place to try to put a utopian blueprint into practice, since the prefecture was severely contaminated by the meltdown at the Fukushima Daiichi nuclear […]
It may be one heck of a coincidence, or it could be the fact that renewable energy causes a major drop in emissions – choose your pick. Remarkable new figures from Spain’s grid operator have revealed that greenhouse gas emissions from the country’s energy sector have fallen by approximately 23.1% last year, as wind and […]
Fuel cells are absolute wonders of technology – electrochemical systems that directly convert the chemical energy of a fuel (hydrogen and oxygen) into electricity and heat. There’s no combustion, and consequently fuel cells aren’t limited by the same thermodynamic cycles as a typical heat engine. A theoretical efficiency of 70% is thus reached – which […]
Volcanoes aren’t generally regarded as being particularly practical for us humans, quite frankly on the contrary. An innovative company from Iceland, however, is suggesting that it may be feasible to produce methanol – a liquid fuel with high heating value that can even work with normal gasoline-powered engines – by refining the CO2 spewed by […]
The world is spending half a trillion dollars on fossil fuel subsidies every year, according to a new report released by the Overseas Development Institude (ODI). Let me say that again: about $500.000.000.000 are spent each year with the aim of promoting the beneficial economic and social outcomes of the oil industry – that’s what […]
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 […]
A 2013 study by MIT indicates that 53,000 early deaths per year occur because of vehicle emissions. Cleaner, more efficient vehicles have been a priority for automakers for years now, but these cars still directly pollute anyway. Electric vehicles, while with current technology still indirectly pollute through their carbon footprint during manufacturing and charging (remember […]
A British company has developed colored but transparent solar cells which add just 10% to the price of the glass they are attached to. Glass and sunlight Oxford Photovoltaics, a spin-off from the University of Oxford, was able to “print” colourful glass that can generate electricity from the sun’s energy; they reported a £2m funding […]
It almost seems too good to be true – a novel device that uses only sunlight and wastewater to produce hydrogen gas could provide a sustainable energy source, while also improving the efficiency of the waste water system. A sustainable, self-driven system In a paper published in the American Chemical Society journal ACS Nano, a […]
France’s ban on hydraulic fracking was completed, with the court upholding a 2011 law which prohibited the practice and cancelled all exploration permits. The decision posted on the court’s website said the ban “conforms to the constitution” and is not “disproportionate,” effectively protecting it from any future legal challenge. In other words, the decision is […]
A new government report by the UK’s Department of Energy And Climate Change shows that the country has reached record rates in terms of the energy it derives from renewable sources, for the second consecutive quarter: 15.5% of the country’s electricity came from renewables, a jump of 5.8% compared to the last period. About half […]
Two years ago, we were telling you about plans for developing the world’s largest solar thermal energy plant in California – a project in which Google invested $168 million. Now, the much anticipated Ivanpah Solar Electric Generating System has finally kicked off! The 14 square km facility (3500 acres) which is backed not only by […]
The World Solar Challenge is a biennial race from Darwin to Adelaide, spanning 3000km of the Australian outback. It attracts teams from around the world, mostly from universities, with 37 teams from 20 countries participating in the 2011 race. What so special about it? All cars need need to be completely solar powered. Innovative and edgy, […]
To my constant surprise and dislike, people continue to think of biofuels as a clean, renewable alternative for the future. People (and especially policy makers) need to rethink the idea of promoting biofuels to protect the climate, because it simply doesn’t work. EROEI Unless you’re working in the energy department (or perhaps marketing), the odds […]
Among the criticism that wind energy gets, one main idea some people complain about is that wind turbines are noisy; some people have even went as far as to claim that even though most of the created noise is way below the range of human hearing (infrasounds), it can cause health problems, including heart issues […]
The Fraunhofer Institute for Solar Energy Systems ISE, Soitec, CEA-Leti and the Helmholtz Center Berlin jointly announced today having achieved a new world record for solar cell efficiency: 44.7% That means that 44.7% of all solar energy (from the Ultraviolet to the Infrared) is gathered and transformed into electricity. After going into research just three […]
Most people don't know this but helium -- the familiar inert gas we all use to inflate party balloons -- is running out at an astonishing rate.
Engineers at Bristol University have developed a microbial fuel cell (MFC) that turns organic matter, in our case urine, into electricity. The fuel cell is equipped on a mobile charger, and its creators envision the device being implemented in various other applications that can recycle urine. Restaurants, bars and various other buildings that employ public toilets might […]
The largest fossil fuel burning country in the world, China, has recently announced plans of extending its solar energy generating capacity to 35 gigawatts by 2015. While it’s far from shadowing the immense amounts of greenhouse gases the country is currently generating (china coal use is expected to increase even further as the country becomes ever […]
It’s no surprise that Germany is just giving lessons in terms of managing renewable energy sources – year after year, the country features more and more cities and now, even villages, which harness most of their energy from renewable sources. Wildpoldsried, a municipality in the district of Oberallgäu in Bavaria has a population of only […]
Hydrogen fuel has been eyeballed by scientists, as well as governments and energy corporations, for many years now as a potential alternative fuel source because of its incredibly high energy. It’s hard to imagine any other non-carbon fuel source capable of driving rockets or high velocity vehicles, like formula 1 sports cars. Besides it being […]
Renewable energy sources, like wind and solar, are gaining ground fast against fossil fuels in terms of energy production, but unfortunately not that fast as we’d hoped for. One big obstacle in the way of renewable energy is storage. A refined look at an older idea that dates back from the XIX century seeks to […]
Especially after the Fukushima events, nuclear energy has been painted black by most of the media, with everybody suddenly realizing just how dangerous and not really desirable it is. But a recent report conducted by NASA showed that as a matter of fact, nuclear energy leads to substantially fewer pollution-related deaths and greenhouse gas emissions […]
For some years now, scientists have been exploring the use of quantum dots as the basis for a novel type of solar cell. The advantages over conventional solar photovoltaic cells are numerous, minus one aspect: efficiency, which is actually the most important one. A new technique developed at MIT labs that uses quantum dots in […]
