FINDING SOURCES OF energy isn’t actually difficult. It comes from wind, from water, from the sun, from the geothermal forces in the heart of the planet itself. The trick is holding onto that energy and moving it around, storing it and then delivering it where people need it. That’s why carbon-based sources like oil are so great. They’re transportable and shelf-stable.
So how will people store and transport energy from renewable sources? Batteries.
Last night, Elon Musk outlined his plan to bring a Tesla battery to homes and offices, generally as an adjunct to solar panels—green energy, on demand. The billionaire CEO unveiled the Powerwall, a battery in 7 or 10 kilowatt-hour sizes. For bigger operations, there’s also a 100 kWh unit called the Powerpack. And the Powerwall doesn’t just let you bank late afternoon solar for late night bingeing; you can also pull power from the grid during off-peak hours. All this for $3,500.
Battery technology is already pretty robust, but it’s never been able to hit such a reasonable price point. “The challenge is to develop a storage system that is economical, with a reasonable payback period for the customer,” says Ping Liu, program director at ARPA-E, the government agency charged with developing new sources of energy. The payback period is your savings over time, by weaning your home off Big Grid.

Batteries don’t store electricity; they store energy. They do this by keeping two different materials—a positively charged cathode and a negatively charged anode—separated by some sort of non-conducting material, categorically called electrolytes. The electrolyte keeps the cathode and anode from touching, but lets molecules pass through. When the terminals (the ends labeled with + and – signs) are connected to an electrical circuit, a chemical reaction inside the battery forces molecules from the cathode to pass through the electrocyte and into the anode. The anode responds by firing off electrons through the negative terminal, and anything wired into the circuit gets power.
The past week saw continued momentum in the global push for a more sustainable fashion industry, some from some surprising sources.
On Monday, the day after John Oliver’s blistering takedown of fast fashion on “Last Week Tonight,” leaders from Sweden, Denmark, Iceland, Norway and Finland presented an action plan to establish their region as a driver of sustainable design, production and consumption by creating a circular economy for garments and textiles no later than 2050.
"Sustainability must not be an accessory," said Kirsten Brosbøl, Denmark's minister of the environment, in her opening remarks. "It has to be straight to the core, and it should be in every fiber."
Brosbøl pointed out that the textile industry is one of the most resource-consuming sectors in the world, noting that a Nordic citizen’s annual consumption of textiles uses more water than a family of three over the course of a year and produces the carbon dioxide equivalent of a 2,000-kilometre car journey. 80 percent of a garment’s environmental impact stems from choices made during the design phase, creating a huge opportunity for designers to minimize the footprint of its textiles.
The plan consists of a four-pronged approach:
Fostering sustainable designers through joint education programs across the Nordic region.Mitigating environmental pollution through a common supply-chain standard, while pressuring the EU to enhance chemical regulations.Cultivating a bigger market for sustainable fashion through responsible procurement and eco-labels.And shifting the market toward greater recycling and reuse of materials.
For those of us in the sustainability field, stakeholder engagement that leads to action is the Holy Grail for creating the change needed for a healthy world and future. So what’s one secret to engaging a worldwide audience in a global ecological imperative in a matter of hours? Recruit someone like Prince Ea to deliver the message.
As environmental NGO Code REDD discovered this week, the celebrity activist, spoken word artist and YouTube sensation was the key to turning its Stand for Trees campaign, launched in February, into a global phenomenon in a matter of hours: “Dear Future Generations” — his new piece inspired by the campaign, debuted Monday — and had 34,539,865 Facebook views and over 231,398 YouTube views as of press time today.
Stand For Trees is the first consumer campaign to use the power of social media and crowdfunding to enable users to take action to reduce deforestation and curb climate change. Supporters are asked to purchase $10 Stand for Trees offset certificates, which each prevent one metric tonne of carbon dioxide (CO2) from being released into the atmosphere while protecting threatened ecosystems that sustain forest communities and numerous endangered species.
As actor Edward Norton, UN Goodwill Ambassador for Biodiversity, said at the launch of the campaign: “Stand for Trees can be a game-changer by harnessing the power of crowdfunding to protect forests, the air we breathe, and the climate that sustains us. It offers a clear and affordable way to make a real difference.”
Tara Button surveys her kitchen and points at her Le Creusetcasserole dish on the drainer. ‘That’s what gave me the idea’, she says. ‘I thought to myself one day last year when I was washing up, I will have this for life – wouldn’t it be great if everything else in my kitchen was like that? You buy it once and you never have to buy it again.’
Tara’s website, Buy Me Once, is launching in early 2016 and aims to be the go to place for finding the most durable products available. She’s curating what she calls the ‘best in show’ when it comes to longevity for every kind of item imaginable, from cutlery and clothing to luggage and children’s toys.
Inspired by her casserole dish, she began thinking that there must be more products out there with a lifetime guarantee, or a promise from the manufacturer that they are designed to stand the test of time.
L'économie circulaire n'a pas fini de nous surprendre. Le Brussels Beer Project croit en ce modèle qui consiste à envisager nos déchets comme des ressources et lance « Babylone », une bière brassée à partir de pain frais recyclé.
Que seraient les moules-frites sans la bière belge qui va avec ? Le Brussels Beer Project croit dur comme fer au pouvoir du précieux breuvage, et œuvre depuis 2013 pour impliquer sa communauté dans des projets collaboratifs : une bière co-créée, des abonnements à vie, une micro-brasserie collaborative… Et récemment, la création de « Babylone », une bière fabriquée à partir de pain.
Sensibles au problème de gaspillage alimentaire qui sévit, les équipes se sont aperçues que le pain représente 12% du gaspillage alimentaire total. Avec ce nouveau projet, elles entendent faire de ce problème une ressource.
En partenariat avec la chaîne de supermarchés belges Delhaize, le Beer Project reçoit chaque jour du pain invendu, frais de la journée. Transformé en farine, il est ensuite utilisé à hauteur de 30% par la brasserie Biers Anders pour en faire une bière de qualité.
La recette est inspirée d’une boisson babylonienne, d’où son nom. Apparemment, « le résultat donne un caractère résolument surprenant avec un nez explosif tirant sur un côté exotique, de belles notes de biscuits toastés et une franche amertume ».
Topher White halted as he drew near the illegal logging camp. He could hear the chain saw rumbling just over the hill, and he suddenly realized how completely cut off this patch of Sumatra’s rain forest really was. For the first time he wondered whether his plan to protect the world’s forests using discarded cellphones was perhaps a little foolhardy.
White is not a violent person. Tall and fit, he is more comfortable channeling his restless energy into problems involving equations and code. And yet here he was, on a path he’d started down in 2011. Back then, White and his girlfriend (who’s now his wife) were volunteering at an ape sanctuary in Indonesian Borneo, when they stumbled upon loggers illegally cutting a tree into two-by-fours. “We had been walking just 5 minutes from the rangers’ station, and yet you couldn’t hear the chain saw,” White recalls.
An idea came to him: He could reprogram used cellphones to listen for the chain saws and motors and then send out alerts to the rangers, taking advantage of the site’s surprisingly good cell coverage and using solar power to provide electricity.
Over the next four years, White overcame nearly all the many obstacles and complications to realize this seemingly simple solution. He’s run trials of the system on the Indonesian island of Sumatra and, more recently, in Cameroon, and he is now moving forward with a number of deployments. Equally important, he’s won the support of environmentalists and forest law-enforcement groups. Randy Hayes, founder of the Rainforest Action Network, calls White’s system “a powerful tool that could do a lot of good on the planet.”
White grew up tinkering. He got into computers early, learning the basics from his father, a computational physicist. Later, as a student at Kenyon College, in Ohio, he rebuilt the college radio station, which had fallen into disrepair.
After graduating with a B.A. in physics in 2004, he became Web chief for ITER, the international consortium that is building a nuclear fusion reactor in southern France. Neil Calder, White’s boss at ITER, recalls that White was never fazed by obstacles: “If something came up, his instant reaction was, ‘Oh, we can fix that,’ and then he’d go on and do it.”
A Japanese company's invention of a machine that converts plastic back into oil shows us how by reducing waste we can lessen our dependence on fossil fuels.
This video brief about the invention of a plastic-to-oil converting machine went viral and exceeded 3.7 million views on YouTube.
This is evidence that concern over “the plastic problem” is certainly not going away, despite encouraging bans on and decreases in the use of plastic shopping bags.
Here on Our World, on the video’s YouTube page and those of re-posters too, as well as on the hot Reddit Science link, the topic has generated much interest and debate amongst commenters.
Many think that this type of recycling is not a solution, but that instead the world should be seriously focused on the first “R” — which is reduce. We should shun single-use plastic (such as your average PET bottle or disposable container) altogether, they argue. The world’s oil resources are diminishing; does technology like this enable our denial of that fact, or is it a hopeful and constructive step in the right direction?
Others are doubtful of the conversion process and have concerns about pollution or toxic residue. But the machine actually uses highly efficient but pretty straightforward pyrolysis: the plastic is fed into the pressurized oxygen-free oven and heated to 427° C (800°F), which liquefies it. The machine then converts the liquefied plastic to gas, which condenses to form a crude oil mixture of gasoline, diesel, kerosene and heavy oil. Blest tells us that, if the proper materials are fed into the machine (i.e., polyethylene, polystyrene and polypropylene — PP, PE, PS plastics), there is no toxic substance produced and the small amount of inert char residue that may be leftover can be disposed of with regular garbage.
They also explain that while methane, ethane, propane and butane gasses are released in the process, the machine is equipped with an off-gas filter that disintegrates these gases into water and carbon.
Lastly, commentators from around the world are anxious to know if and where they can purchase a machine. Though the company still mainly produces larger, industrial-use machines, Blest Co. will be more than happy to hear from you. Please contact them directly at firstname.lastname@example.org.

One of the greatest challenges facing governments and companies around the world is how to influence consumers into developing more sustainable buying habits and lifestyles. There is a significant opportunity for businesses to help consumers make major changes in their lifestyles and purchasing habits.
If the global business community is to thrive in the long term — and carry us to that flourishing future we are trying to imagine and help build — it needs to continue to scale up the ambition and influence of its efforts. That’s much easier said than done, of course, though we are seeing a number of encouraging trends within the Sustainable Brands community that, while still nascent, are promising to deliver a lot of value for years to come. Here is a list of 10 such trends that are top of mind for our team at the moment.
1. The growing list of celebrities supporting sustainability-driven communication campaigns
2. Quality humor, edgy terms and instant meme-ability in marketing and advertising campaigns
3. Transparency campaigns gaining momentum but scrutinized ever more closely
4. Intensifying collaboration between the peer-to-peer and mainstream economies
5. A growing ecosystem of players and initiatives around circular business models
6. New horizons for city-brand partnerships in implementing new solutions together
7. Powerful synergies await us when our homes get truly connected and smart
8. Major pivots in favor of shifting product portfolios with sustainability-driven criteria in mind
9. Radically local supply chains that are logistically possible, commercially viable and brand-aligned
10. The mighty force created by combining employee engagement with impact investing
Broadband market enters a new era following the NBN strategic review. The National Broadband Network continuing evolution Since being implemented in 2012, Australia's NBN has undergone significant changes. The late-2013 strategic review of the NBN, commissioned by a newly elected government, established a very different framework. Instead of 93% of the population being covered by FttP, the new architecture has called for a hybrid network incorporating FttP and FttN, and utilising existing DSL and HFC plant.
The New York City Council, the EPA, the Natural Resources Defense Council, Alliance for Climate Education (ACE) and Global Kids held a joint press conference Wednesday morning on the steps of New York City Hall to push for statewide climate education for K-12 schools in New York. And earlier this week in San Francisco, Mayor Ed Lee announced a new partnership with ACE that will provide climate education to all San Francisco public high school students.
