Bacteria could lead to cleaner methane power
Methane as a greenhouse gas isn't all that eco-friendly when used for power, but scientists might have a way to keep the damage to a minimum. Penn State researchers have crafted microbial fuel cells that can convert methane into electricity right at the well, without leaking loads of gas into the atmosphere by sending it through pipes. The team created a cocktail of bacteria (including a synthetic microbe you can't normally grow) that produces the necessary materials to grab and transport electrons from the methane. Not only is this a relatively clean process, the bacteria can run on waste products -- it might clean up the site as it generates power.
Tesla's Solar Roof is available for pre-order
Tesla didn't quite fulfill its promise to start Solar Roof sales in April, but you thankfully haven't had to wait that much longer to pull the trigger. As of today, you can pre-order Tesla's stealthy solar power cells in textured or smooth variants ahead of the first US installations in the summer (2018 elsewhere). While the price will vary depending on your home, of course, the company estimates that a "typical" buyer will pay about $21.85 per square foot instead of $24.50 for a regular roof. Not that there will be much mystery regardless of what you pay -- Tesla is offering a cost calculator to figure out your real-world expenses.
Britain has its first day of coal-free power in 135 years
Coal power has been a fixture of British culture ever since the country's first plant went live in 1882. It shaped the Industrial Revolution (and the air pollution that followed), was involved in major labor disputes and even led to a famous album cover. However, the country is now backing away from coal -- and it just achieved an important milestone in weaning itself off of this dirty energy source. The National Grid has confirmed that, on April 21st, Britain went without coal-generated power for its first full day in 135 years. There had been relatively long stretches in recent times (19 hours in May 2016, for instance), but none as long as this.
Apple is on a mission to only use recycled materials
With the release of its new environmental report, Apple is looking to push the envelope of what it can do for the good of the planet. Last year, it boasted about how much cash its recycling efforts had saved it, including $40 million worth of gold re-used from old devices. This year, it's talking about "closing the loop" on its use of raw materials, potentially redefining how gadgets are made altogether.
Tesla's sleek solar panels are easier to install on your roof
Tesla's home energy efforts might be centered around its solar roofs, but it knows that not everyone can (or wants to) rip up their roof just to bring renewable energy to their home. To that end, the company is offering a first glimpse at Panasonic-made solar panels that would go on top of your existing roof. Unlike many aftermarket options, this would be relatively slick and unintrusive -- the panels have "integrated front skirts and no visible mounting hardware." While it'll be patently obvious that you have solar energy on your roof, it shouldn't be the eyesore you sometimes get with conventional designs.
Coal's sharp decline leads to a drop in US energy production
Whether you like it or not, coal power is on the decline... and that's having a marked impact on American energy output. The US Energy Information Administration has published data revealing that the country's 2016 energy production dropped over year-over-year -- the first such drop since 2009. Most of it can be pinned on coal, whose output fell a steep 18 percent compared to 2015. Other energy sources dipped as well, but not by nearly as much. Natural gas and crude oil were down 'just' 2 and 7 percent respectively.
Dear Donald Trump: 'Clean coal' doesn't exist
"Clean coal" is an oxymoron. Even if you took a hunk of coal, doused it in bleach and scrubbed it for six hours with a soapy horsehair brush, it would still cause lung cancer and fill the air with carbon emissions when you burned it. Anyone who says otherwise is lying. However, the phrase "clean coal" is ridiculously tenacious in public discourse. Just this week, President Donald Trump used it: As he signed an executive order rolling back a bevvy of environmental protections laid out under the Clean Power Plan, he turned to the coal miners staged around his desk and promised to "end the war on coal and have clean coal, really clean coal." The president of the United States is lying.
What Trump's budget would mean for NASA and climate change
President Donald Trump's proposed 2018 budget beefs up the Defense Department while removing funds from the Environmental Protection Agency, Department of Energy, NASA and many other government agencies. Congress still has to pass the budget, but if it's approved it will shut down a handful of programs designed to research and combat climate change. Despite overwhelming consensus in the scientific community, multiple members of the Trump administration have argued that climate change is not a man-made occurrence, including new EPA head Scott Pruitt. So, it's not surprising that Trump's proposed budget slashes climate change research programs and funding -- but it is concerning.
Trump to sign sweeping rollback of Obama-era climate change rules
Donald Trump is poised to sign an executive order that will dramatically reduce the role that climate change has in governmental decision-making. The order could impact everything from energy policy to appliance standards.
Liquid battery could last for over 10 years
Modern batteries aren't hampered so much by their capacity as their long-term lifespan -- a lithium-ion pack can easily become useless after a few years of heavy use. That's bad enough for your phone, but it's worse for energy storage systems that may have to stick around for the long haul. If Harvard researchers have their way, you may not have to worry about replacing power backs quite so often. They've developed a flow battery (that is, a battery that stores energy in liquid solutions) which should last for over a decade. The trick was to modify the molecules in the electrolytes, ferrocene and viologen, so that they're stable, water-soluble and resistant to degradation. When they're dissolved in neutral water, the resulting solution only loses 1 percent of its capacity every 1,000 cycles. It could be several years before you even notice a slight dropoff in performance.
China is now the biggest producer of solar power
You probably don't think of China as a clean energy champion given its frequent problems with smog and continued dependence on coal power, but you may have to rethink your views after today. The country's National Energy Administration has revealed that its solar power production more than doubled in 2016, hitting 77.42 gigawatts by the end of the year. The country is now the world's biggest generator of solar-based electricity in terms of capacity -- it doesn't compare as well relative to population (Germany, Japan and the US could easily beat it), but that's no mean feat for any nation.
GM and Honda will mass-produce hydrogen fuel cells together
Just weeks after the car and energy industries began their big push on hydrogen, the first real action is being taken. General Motors and Honda have leapt into bed together to begin work on a new factory that'll mass-produce hydrogen fuel cells for their vehicles. Fuel Cell System Manufacturing (FCSM) will be based at GM's electric vehicle battery site in Brownstown, MI (pictured), and is expected to start work in 2020.
China suspends plans for 85 coal power plants
China is taking some steps to curb pollution (it doesn't have much choice), but one of its most recent steps may be more of a happy accident. The country's National Energy Administration is suspending 85 planned or in-progress coal power plants -- not because they're threats to the environment and public health (which they are), but because they don't fit in with China's latest Five Year Plan. It's targeting a coal capacity limit of 1,100GW, but the plants would have brought it to 1,250GW. While that's still an increase over the current 920GW capacity, it's definitely an improvement.
Japan axes its 'fast' nuclear reactor prototype
Japan's Monju reactor was supposed to be a more efficient alternative to conventional nuclear power. The "fast," sodium-cooled prototype plant would produce more plutonium than it ate up, making it relatively easy to recycle fuel. However, that's not how it worked out. A leak and fire led to a 15-year shutdown starting in 1995, and the reactor has been plagued by failures, mismanagement and political fights ever since. And now, the government has had enough: it's planning to close Monju once and for all. It would be slower and more expensive to fully restart the reactor than to shut it down (the equivalent of $4.6 billion versus $3.2 billion), officials claim, and the focus is on developing more practical fast reactors instead.
Fusion reactor endurance record hints at our energy future
Wondering why a fusion reactor isn't powering your home right now? There are numerous reasons, but one of the biggest is simply keeping the necessary super-hot plasma in an ideal state for energy generation -- it doesn't last that way for long. South Korea, however, just edged closer to that goal. The country's KSTAR (Korean Superconducting Tokamak Advanced Research) reactor team claims to have set an endurance record for operating with "high performance" plasma. The feat only lasted for 70 seconds, but that's still a "huge step forward," according to the National Fusion Research Institute.
Google expects to run solely on renewable energy in 2017
Google has made it a point to run as much of its business on renewable energy as possible, and it looks like the company is close to reaching its ultimate goal. The internet pioneer now expects that all of its offices and data centers will be relying on purchased solar or wind power by some point in 2017. This isn't the same as directly powering facilities with eco-friendly energy (logistics and the nature of electrical grids makes that difficult), but it does mean that Google is funding enough projects to offset its massive power demands -- 5.7 terawatt-hours in 2015.
Solar beads can make some very cool lamps and flashlights
Conventional solar panels aren't exactly the prettiest objects on the planet, which is why companies like Tesla, SRS Energy and SunTegra have been focusing on blending this technology into roof tiles. As for those who don't have a roof or land to spare, Japan's Kyosemi Corporation has come up with an alternative solution that can let windows and glass walls soak up solar power as well. The magic ingredient? Just a web of "Sphelar" solar cell beads -- each with a diameter of 1.2 mm -- lined up inside any transparent substrate, meaning it can come in any shape or form while letting light travel through the gap between beads. Better yet, due to the spherical nature of these cells, they can capture light from almost any angle -- to the point where they can deliver a higher cumulative output than their conventional counterparts, according to the company.
Scientists confirm twisty fusion device's odd magnetic fields
Now that the first large version of a extraordinarily complex, cruller-shaped stellarator fusion device is up and running, there's an overriding question: is it behaving the way scientists expected? Thankfully, the answer is yes. Researchers have confirmed that Germany's Wendelstein 7-X stellarator is producing the 3D magnetic fields that were anticipated from its twisty design. In fact, it's faithful to the concept with "unprecedented accuracy" -- the error rate is less than one in 100,000.
MIT's sensor network tracks your power-hungry appliances
You get a bill from your electricity provider every month laying out how much energy you used, but there's no easy way to get a breakdown of which appliances suck down the most juice. But the US Navy has partnered with MIT scientists to design a cheap, portable sensor network that tracks the power drain of each of your domestic devices.
Tesla runs an entire island on solar power
Now that Tesla has officially acquired SolarCity, it's not wasting any time showing what the combined entity can do. Tesla has revealed that it's running the island of Ta'u (in American Samoa) on a solar energy microgrid that, at 1.4 megawatts, can cover "nearly 100 percent" of electrical needs. It's not just the 5,328 solar panels that are key -- it's the 60 Tesla Powerpacks that offer 6 megawatt-hours of energy storage. While Ta'u is normally very sunny, the packs can keep it running for three days without sunlight. They don't have to worry about a cloudy day leading to blackouts.
