Indonesian president gives forest management back to indigenous communities

Filed under Eco, Green

After decades of conflict over the power to oversee Indonesia’s forests, President Joko Widodo gave management rights back to nine indigenous communities. According to the World Agroforestry Centre, millions of indigenous people cared for forests sustainably for centuries until the Dutch colonial government declared state ownership, and this moment marks an important milestone in the acknowledgement of indigenous rights . For years, indigenous communities have fought for recognition as their rights have been contested by the government – even after independence in 1945, according to the World Agroforestry Centre. There are thousands of distinct ethnic groups across the islands of Indonesia, and Widodo recently took what the center described as a highly symbolic step in formally granting forest management titles to the nine indigenous communities. In a speech on the occasion, Widodo said, “Recognition also means an appreciation of Indonesia’s original values and its identity as a nation.” Related: Indonesian president announces plan to halt palm oil industry expansion Widodo cited the Kajang people, one of the nine communities, in his speech as an example from which others could benefit. An earlier national government altered the Kajang’s forests’ management status from indigenous to “production forests with limited uses” so the government could control them and parcel some land out for rubber plantations. But the Kajang developed “a set of local regulations that affirm, recognize, and protect based on traditional management,” according to Andi Adriardi, a member of a non-governmental organization that helped the Kajang regain rights. They coordinated with the local government and organizations to reclaim the title. Adriardi said the government recognized their case as a “good lesson that approaches perfection” for a well-managed forest. Kajang leader Andi Buyung Saputra, pictured above with Widodo, said in his acceptance speech, “Our traditional wisdom has played an important role in managing and preserving our forests. This has contributed to keeping our Earth greener and reducing the negative impacts of climate change .” Via World Agroforestry Centre Images via World Agroforestry Centre and Wikimedia Commons

New super-thin film acts like "air conditioner" for buildings

February 13, 2017 by  
Filed under Eco, Green

Engineers at the University of Colorado Boulder have developed a thin, artificially structured “metamaterial” that can cool objects without the use of water or energy. The film works to lower the temperature of the surface beneath it through a process known as “passive cooling,” meaning that it vents the object’s heat through thermal radiation while bouncing off any incoming solar energy that may negate those losses. As described last week in the journal Science , the glass-polymer hybrid material could provide an “eco-friendly means of supplementary cooling” for thermoelectric power plants, which require colossal amounts of water and electricity to keep their machinery chugging along at optimum temperatures. The film measures a lithe 50 micrometers thick, or just slightly more substantial than the aluminum foil you’d find in your kitchen. And, much like foil, researchers say it can be easily and economically manufactured by the roll for large-scale residential and commercial applications. “We feel that this low-cost manufacturing process will be transformative for real-world applications of this radiative cooling technology,” Xiaobo Yin, an assistant professor who co-directed the research, said in a statement. Buildings and power plants aren’t the only structures that could benefit, Yin said. The material could keep solar panels from overheating, allowing them to not only work longer, but harder, as well. Related: 3D-printed “Cool Brick” cools a room using only water “Just by applying this material to the surface of a solar panel, we can cool the panel and recover an additional one to two percent of solar efficiency,” said Yin. “That makes a big difference at scale.” Yin and his cohorts have applied for a patent as a prelude to exploring potential commercial applications. They also plan to create a 200-square-meter “cooling farm” prototype in Boulder sometime this year. “The key advantage of this technology is that it works 24/7 with no electricity or water usage,” said Ronggui Yang, a professor of mechanical engineering and a co-author of the paper. “We’re excited about the opportunity to explore potential uses in the power industry, aerospace, agriculture and more.” + University of Colorado Boulder Photo by Chris Eason

Stanford researchers pioneer world’s first affordable urea battery

February 13, 2017 by  
Filed under Green

Stanford University researchers have designed a new battery that could revolutionize renewable energy storage . Using urea , an affordable, natural and readily available material found in mammal urine and fertilizers, their battery is notably more efficient than past iterations. The battery, developed by Stanford chemistry professor Honjie Dai and doctoral candidate Michael Angell, uses an electrolyte made from urea – a material already produced in mass industrial quantities for use in plant fertilizers. Non-flammable and made with electrodes from abundant materials like aluminum and graphite, the battery presents a low-cost way for storing energy from many sources – including renewables . “So essentially, what you have is a battery made with some of the cheapest and most abundant materials you can find on Earth. And it actually has good performance,” says Dai in a press release. “Who would have thought you could take graphite, aluminum, urea, and actually make a battery that can cycle for a pretty long time?” Dai and his team were the first to make a rechargeable aluminum battery in 2015, which charged in less than a minute, while lasting for thousands of charge-discharge cycles. And they’ve improved on both the performance and cost of their latest model, which is about 100 times cheaper than the 2015 battery, with a higher efficiency of 1,500 charge-discharge cycles and a charging time of 45 minutes. This is also the first time that urea has been used to make a battery. Related: MIT researchers invent ingestible battery powered by stomach acid Energy storage is a huge challenge for solar power and other renewables, as users need a reliable way to store power for when their systems aren’t producing energy. The batteries currently on the market, including lithium ion and lead-acid batteries tend to be quite costly and don’t last that long. But Dai and Angell believe their battery might be the solution to the conundrum of renewable energy storage. “It’s cheap. It’s efficient. Grid storage is the main goal,” says Angell. “I would feel safe if my backup battery in my house is made of urea with little chance of causing fire,” added Dai. The researchers have licensed their battery patents to AB Systems, a company founded by Dai, and a commercial version of the battery is on the way. They’re planning to work on increasing its life span down the road by further investigating its internal chemical processes.

Comments Off on First Wattway solar road pilot in US pops up in rural Georgia

The first Wattway solar road pilot in America has popped up in rural west Georgia . The Ray C. Anderson Foundation , named for sustainable manufacturing pioneer Ray Anderson, is testing renewable technologies along an 18-mile stretch of road, and recently installed 538 square feet of Colas ‘ Wattway solar road system near the border between Georgia and Alabama. Part of Georgia’s Interstate 85 was named for Anderson, but as over five million tons of carbon dioxide are emitted yearly on that road portion alone, Anderson’s family felt placing his name there didn’t honor his legacy, and began to look into renewable technologies to clear the air – so to speak. Thus began The Ray , an 18-mile living laboratory for clean technologies, including not only the solar roads, but also a solar-powered electric vehicle charging station , and WheelRight , a system people can drive over to test their tire pressure, which could lead to improved fuel inefficiency. Related: France officially opens the world’s first solar panel road The first Wattway solar panel pilot is part of The Ray near a Georgia Visitor Information Center in West Point, Georgia. According to Wattway by Colas, the average expected output for the 538-square-meter pilot is anticipated to be 7,000 kilowatt-hours per year, which will help power the center. And these technologies are just the beginning. The foundation will also construct bioswales , or shallow drainage ditches filled with native Georgia plants to capture pollutants during rain. In a right-of-way space, they’ll build a one megawatt solar installation . They’re working with the Georgia Department of Transportation to bring such ideas to life along the 18-mile road stretch. Not only will several of their projects beautify the highway, but will generate clean energy and bring in money for investors. And other parts of the state have shown interest in building their own Wattway roads. The Ray executive director Allie Kelly dreams of a day when highways will “serve as a power grid for the future,” but she believes that day is coming sooner than we may think. She told Curbed, “We’re at a tipping point in transportation . In five to ten years, we won’t remember a time when we invested a dime in infrastructure spending for a road that only did one thing.” + The Ray + Wattway by Colas Via Curbed Images © Valerie Bennett and via The Ray

Comments Off on Bill Gates warns against climate-change denial

Billionaire philanthropist Bill Gates recently spoke out against denying climate change during a student question-and-answer session at Columbia University in New York City earlier this month. Joined by voluntary tax-information sharer and fellow monied person Warren Buffett , the Microsoft founder also called for greater innovation in clean energy. He said, “Certain topics are so complicated like climate change that to really get a broad understanding is a bit difficult and particularly when people take that complexity and create uncertainty about it”. And Gates is more than happy to put his money where his mouth is. In December, he and a team of investors said they would pump more than $1 billion into Breakthrough Energy Ventures , a fund that invests in technologies that will curtail the planet’s greenhouse-gas emissions. Related: Bill Gates pledges $2 billion to renewable energy research We need to find energy that’s “reliable, cheap, and clean,” he said, before promising that “the innovations there will be profound.” He added, “There are many paths to get to where we need to go”.

Electric cars and solar power could freeze fossil fuel growth by 2020

Comments Off on Electric cars and solar power could freeze fossil fuel growth by 2020

Fossil fuels could officially be a thing of the past as early as 2020, according to a new report. The report shows the declining costs of electric vehicles and solar energy could put a stop to the growth in worldwide demand for oil and coal in less than three years time. According to the Guardian , a report by the Grantham Institute at Imperial College London and the Carbon Tracker Initiative entitled “ Expect the Unexpected: The disruptive power of low-carbon technology,” polluting fuels could lost 10 percent of their market share to solar power and “clean cars” within a decade. To put it in perspective, a 10 percent market share loss was enough to cause the recent collapse in the U.S. coal industry , while the five major utilities in Europe collectively lost about $100 billion between 2008 and 2013 because they didn’t ready themselves for the 8 percent growth in renewable energy . Related: Ireland votes to be the world’s first country to fully divest from fossil fuels According to the study , “Big energy companies are seriously underestimating the low-carbon transition by sticking to their “business as usual” scenarios which expect continued growth of fossil fuels, and could see their assets “stranded.” The study also notes that solar photovoltaic power could supply 23 percent of global power generation by 2040, and as much as 29 percent by 2050. That’s enough to entirely phase out coal and leave natural gas with just a 1 percent market share. At the same time Exxon is predicting renewables will supply just 11 percent by 2040. The researchers also see electric vehicles making up about 35 percent of the road transport market by 2015, and as much as 67 percent by 2050. That growth trajectory will see EVs displace about two million barrels of oil per day in 2025, and grow to 25 million barrels per day by 2050.

Comments Off on Torontos 8 Winter Station winners to revive citys frozen beaches

Toronto’s freezing beaches will soon be a hotspot of activity. The third annual Winter Stations design competition recently unveiled this year’s eight winners, a series of temporary art installations that will take over the city’s east end beaches beginning February 20. These interactive pieces will be built atop ordinary lifeguard stands and offer designs ranging from a Japanese onsen-inspired installation to a modern lighthouse. The Toronto Winter Stations competition selected five professional and three student teams to create temporary sculptures for the Toronto beachfront created under the theme of “Catalyst.” The competition seeks visionary designs that reinvent the waterfront landscape into an inviting and memorable place during a time of year when the frozen beaches are normally deserted. “Winter Stations 2017 delivered, once again, gutsy and lyrical transformations of ordinary lifeguard stands,” said Lisa Rochon, Winter Stations Design Jury Chair. “Visitors will be able to touch and feel their way along the beach, experiencing luminous shelter from the wind, warming waters for their feet, and designs that celebrate the Canadian nation of immigrants.” Related: 7 Burning Man-style winter stations unveiled for Toronto’s snowy shores The winning entries in the professionals category include: Asuka Kono and Rachel Salmela’s I See You Ashiyu, an installation where visitors can dip their feet into a Japanese hot spring-inspired basin; studio PERCH’s North, a suspended forest of 41 trees hung upside down; Mario García and Andrea Govi’s Collective Memory built from recycled bottles in reference to a statistic that says nearly one-half of the Canadian population over the age of 15 will be foreign born or a child of a migrant parent by 2031; Dionisios Vriniotis, Rob Shostak, Dakota Wares-Tani and Julie Forand’s BuoyBuoyBuoy, a reflective sculpture mimicking the motion of multiple buoys; and Joao Araujo Sousa and Joanna Correia Silva’s modern interpretation of a lighthouse in The Beacon, which will also double as a drop-off location for non-perishable items like canned food or clothes. The selected student works include University of Waterloo’s Flotsam and Jetsam that speaks to the ills of plastic consumption; Humber College School of Media Studies & IT, School of Applied Technology’s the Illusory that uses mirrors to distort perspectives; and Daniels Faculty of Architecture, Landscape, and Design, University of Toronto’s Midwinter Fire, which immerses visitors in a miniature version of a Southern Ontario winter forest. + Winter Stations Via ArchDaily Images via Winter Stations

Myron Ebell says Trump plans to abolish the Environmental Protection Agency

Comments Off on Myron Ebell says Trump plans to abolish the Environmental Protection Agency

Climate change denier Myron Ebell recently hinted serious changes could be made to the Environmental Protection Agency (EPA) under the Donald Trump administration. In a telling new interview, he said the agency could reopen a review of car fuel efficiency standards, and withdraw or change climate education information. Ebell called Trump’s campaign goal to scrap the agency an “aspirational goal”. The EPA won’t be gone tomorrow, but Ebell indicated its functions could be radically curtailed as Trump hopes to farm out many EPA roles to states instead. The agency has existed since 1970, to safeguard public health and the environment . But Trump reportedly thinks many of these duties would be better left to states. Related: Insider says Trump could pull America out of Paris deal within days Speaking to The Guardian, Ebell said, “To abolish an agency requires not only thought but time because you have to decide what to do with certain functions that Congress has assigned to that agency. President Trump said during the campaign that he would like to abolish the EPA or ‘leave a little bit.’ It is a goal he has and sometimes it takes a long time to achieve goals.” The Guardian noted Ebell does not speak for Trump. However, many of his statements echo those of new White House staff, including the president. As the leader of the Trump EPA transition team, Ebell worked on a method to withdraw from the Paris agreement and ditch President Obama’s Clean Power Plan . It’s up to whomever will lead the EPA now to follow through on those ideas, but as Trump’s pick is sue-happy Scott Pruitt , it’s not far-fetched to imagine he might follow up on Ebell’s environmentally damaging dreams should he be confirmed. In the past, Ebell said two-thirds of the EPA’s 15,000 scientists, engineers, and researchers could be cut. Such a move would be ironic for Trump, who’s staked many of his actions on the impression they create jobs . Ebell described himself on his Twitter page as the “number one enemy of climate change alarmism,” and directs the Competitive Enterprise Institute, which Greenpeace once slammed for a video of theirs that claimed carbon dioxide isn’t a pollutant.
