The house doesn’t look like a futuristic spaceship, but it is different from the other small pre-fab houses along the street. It is a two home duplex with a big wooden porch in front and, of course, solar panels on the roof.
Lakiya’s house started out two years ago as an entry in the Department of Energy’s biannual Solar Decathlon. Dubbed “Empowerhouse” for the competition, it was an ambitious concept brought to life by engineering and architecture students from Stevens Institute of Technology, Parsons The New School for Design and Milano School for International Affairs, management and Urban Policy, many of whom had never even wielded a hammer before attempting this elaborate construction project. The team’s dream was to build a solar-powered house that could not only compete with the most cutting-edge technologies out there, but was actually affordable and something ordinary people would want to live in.
According to Josh Layrea, one of the Stevens engineers, the winning entry from a German team two years before cost over two million dollars. “It was an impressive piece of engineering,” Laryea concedes. “But made for exhibit, not habitation. The entire outside of the house was covered in solar panels.” Laryea and his teammates had a different goal. In a way, they were in a competition of their own, in which they were competing against themselves to see if they could create something that Habitat for Humanity could use not only as a home for a low-income family in the Deanwood area of D.C. but also as an affordable housing prototype for Habitat going forward. The Stevens-Parson-Milano house won the top prize for cost-effectiveness at the Solar Decathlon.
Lakiya’s house was built based on passive house design principles. The basic concept of passive house is to lower energy consumption by being super-insulated and practically airtight. Empowerhouse has 12-inch thick walls and triple-glazed windows and, as a result, uses up to 90 percent less energy for heating and cooling than an ordinary house. Such low energy consumption enabled Empowerhouse to have one of the smallest solar panel arrays in the competition, which helps keep construction and maintenance costs down.
As anyone who worked on Empowerhouse hoped, Lakiya’s home is not the end of the dream. Habitat is gearing up to build six more passive houses in Ivy City, a short drive from Deanwood. They’ll look a bit different from Empowerhouse, more townhouses than duplex, but they’ll cost about the same and hopefully pass on the same savings.
“As much as we can afford, we would like to have the highest standard of energy efficiency available for our homeowners,” said Susanne Slater, President and CEO of D.C. Habitat for Humanity. “Our whole mission is to provide affordable housing to low income families, and if homeowners pay less in energy costs, that helps us reach that goal.”
“I really believe that with the mounting cost of electricity, passive houses with solar panels are going to take off,” said Slater. “And our homeowners are going to be out in front of the movement.”

From ‘Infrographic: What’s in Obama’s Climate Plan?‘ by Heather Libby:
In a major speech today, U.S. President Barack Obama has made the fight against climate change a priority for his second term. Saying he “refuses to condemn your generation and future generations to a planet that’s beyond fixing,” Obama outlined the first comprehensive U.S. Climate Action Plan. […] While the details of much of the Plan have yet to be decided and his continued support for natural gas and carbon capture and sequestration will likely be met with criticism, Obama’s all-encompassing plan to tackle climate change is being seen as a positive signal for bold action from the United States.

From the article No excuses, no regrets: we can adapt agriculture to climate change now by Vanessa Meadu:
Imagine you’re working for your country’s government and you’ve been given the formidable task of developing a strategy to help the agriculture sector adapt to climate change. Working out how climate models will play out on the ground for farmers, and conceiving options for farmers to adapt is sophisticated stuff, and the challenge is only compounded when the best information remains somewhat uncertain.
You might easily be discouraged, when faced with data and projections that are not sufficiently specific, only applicable for certain crops, or simply missing altogether. Often this uncertainty becomes a political weapon, wielded as an excuse for inaction. But a new analysis published in the journal PNAS debunks such excuses by showing how scientists and governments can cut through uncertainty and make the most of existing knowledge, however conflicting or weak. In fact some countries have done exactly that, and “embraced “no-regrets” adaptation: actions that will benefit farmers and society regardless of specifically how and when climate change plays out on the ground.”
The paper Addressing uncertainty in adaptation planning for agriculture is co-authored by researchers from the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS), the International Water Management Institute (IWMI), the International Center for Tropical Agriculture (CIAT), the International Livestock Research Institute, and leading universities (Oxford, Leeds, Reading). The researchers point to examples around the world where governments have taken crucial first steps to safeguard food and farming, even when information was weak.

From the article “Energy co-ops are cutting household bills alongside carbon emissions” by Simon Birch
For customers, trust is key when it comes to getting advice on improving energy efficiency – and co-operatives have the edge.
Ruth Rosselson is an environmental pioneer. The freelance writer and community trainer is one of the first homeowners to sign up with the Manchester-based Carbon Co-op for a programme of energy-efficiency improvements that will transform her cold and draughty house into a warm and toasty low-energy home. “The main motivation for making my house more energy-efficient is that currently it’s so cold and damp,” says Rosselson, 42, speaking from her Manchester semi that she shares with her partner, Justin. “We also care deeply about the global environment and so we wanted to improve the carbon efficiency of the house.”
Carbon Co-op, which launched in 2011, is one of a new generation of co-ops that are now aiming to address the critical issue of climate change by making houses more energy-efficient, which in turn will slash carbon emissions and in the long-run save homeowners money. “The UK has a legally binding target for cutting carbon emissions by 80% by 2050 from a 1990 baseline,” says Carbon Co-op’s Jonathan Atkinson. “At the same time, escalating fuel bills are leading to more and more people experiencing fuel poverty. Consequently we’re aiming high and offering packages of retrofit improvements to householders that will cut both energy bills and carbon emissions.” […]
“We take the whole house approach to retrofitting and recommend a package of complementary measures such as wall and loft insulation that will improve the energy performance of a house,” says Atkinson. “And because we have a strong ethical strand to our work, we aim to source materials from local businesses such as highly energy-efficient windows from the Green Building Store in West Yorkshire.”
So what’s the key benefit of operating as a co-op in this sector? “The big issue in the retrofitting industry is that of trust,” replies Atkinson. “The big energy companies dominate the energy-efficiency market because they are forced to by Ofgem, the energy regulator. However, very few people trust the big energy companies any more because of the recent mis-selling scandals.” He says people are increasingly suspicious of energy companies trying to sell them big-scale changes, thinking that all the companies want is for their bills to increase. “As a co-op, we’re community orientated and householder-owned with no external shareholders,” says Atkinson. […]
The Birmingham-based Energy Saving Co-op, which like Carbon Co-op launched in 2011, has similar ambitions to be a national player in the energy-efficiency retrofit market. “We’ve already retrofitted 50 homes with a target of completing 600 homes by the end of the year, two thousand homes in 2014 and a plan to eventually operate nationally,” says the chief executive and co-founder Ewan Jones, who aims to fund this expansion programme through its current share offer.
Financing the retrofit ambitions of both Carbon Co-op and the Energy Saving Co-op is a major challenge though both co-ops and the wider co-op movement are set to benefit from the green deal, the government’s flagship programme to make millions of homes more energy-efficient, which was launched this year. Essentially a type of personal loan where you pay for the work over time through your energy bill, the green deal is set to kickstart the energy-efficiency market – and co-ops and social enterprises are lining up to take a slice of the action. The Energy Saving Co-op, for example, is now working with a number of co-ops which will act as green deal energy assessors including Energywise, a new Birmingham co-op and the Jericho Foundation, a social enterprise which will install the energy saving kit.

From the Food Climate Research Network (FCRN):
This study is “based on a very small set of interviews – 16 people who self-identified as deliberately trying to live a lower-carbon lifestyle because of concern about climate change – and so its findings don’t necessarily apply to other people living in lower carbon ways. However, what is interesting about it is that it shows that people’s motivations for living in less carbon intensive ways are not primarily environmental. A concern for social justice is often much more important, as well is a desire for a more equal society” FCRN mailing: 5 March 2013.
This exploratory mixed-methods study uses in-depth interviews to investigate the values, motivations, and routes to engagement of UK citizens who have adopted lower-carbon lifestyles. Social justice, community, frugality, and personal integrity were common themes that emerged from the transcripts. Concern about ‘the environment’ per se is not the primary motivation for most interviewees’ action. Typically, they are more concerned about the plight of poorer people who will suffer from climate change. Although biospheric values are important to the participants, they tended to score altruistic values significantly higher on a survey instrument. Thus, it may not be necessary to promote biospheric values to encourage lower-carbon lifestyles. Participants’ narratives of how they became engaged with climate action reveal links to human rights issues and groups as much as environmental organisations and positive experiences in nature. Some interviewees offered very broad (positive) visions of what ‘a low-carbon lifestyle’ means to them. This, and the fact that ‘climate change’ is not necessarily seen as interesting even by these highly engaged people, reveals a need for climate change mitigation campaigns to promote a holistic view of a lower-carbon future, rather than simply offering a ‘to do’ list to ‘combat climate change’.

Screenshot from the Global Climate Action Map website
An initiative of the Climate Institute, the Global Climate Action Map is an interactive tool for exploring what countries around the world are doing in terms of policy action on climate change. It’s a great way of learning about how governments are addressing issues such a renewable energy and emissions targets, carbon pricing, energy efficiency, forest and farming emissions, and emissions standards.
From the Global Climate Action Map website:
Aim: All major emitting countries are implementing policies to reduce emissions, drive clean energy investment and improve energy efficiency. This is driven by a range of factors including the need to reduce local and global air pollution, avoid environmental degradation, improve energy security and build new industries and employment opportunities. This map, while not exhaustive, seeks to provide a summary of high-level national actions on climate change.
Purpose: While countries representing over 80 per cent of global emissions have now committed to reduce or limit greenhouse gas emissions, the current commitments on the table mean the world is still heading for 3-4 degrees of global warming. Current national policies are a foundation to build upon, but more cooperation and increased ambition is needed to truly address the challenge.

A local resilience-building project about climate extremes.
Visions of Resilience: Anglesea 2037 is part of a larger research project Transforming Institutions for Climate Extremes. This project is led by Che Biggs at the Victorian Eco-Innovation Lab (VEIL) at the University of Melbourne. It aims to understand how communities and institutions can prepare and become more resilient to disruptive climate conditions. Anglesea was chosen as an ideal case-study site because it faces multiple climate hazards such as fire, drought and sea level rise but it also has a creative community and a strong local identity.
What is the Visions of Resilience: Anglesea 2037 blog about?
The images and articles you see on the Visions of Resilience: Anglesea 2037 blog are glimpses of possible futures. They depict strategies and ideas about how Anglesea could become more resilient to the more extreme possible impacts of climate change. The ideas represented have been developed from a workshop involving Anglesea community members. In the workshop people were asked to propose adaptation strategies in response to a series of challenging future scenarios that describe Anglesea in the year 2037. These scenarios were built from an assessment of climate model projections, historical records from along the Great Ocean Road and interviews with Anglesea residents. The small number of glimpses you see were combined and synthesised from more than 100 ideas developed in the workshop. Treat them as a window into a range of possible futures that might exist. We encourage you to comment on what is good or not good about the way they respond to challenges from climate change.
Why this project? When managing disaster risk, government and private sector organisations often rely heavily on ‘probability’ or ‘expert’ assessments of the likely type, extent and frequency of negative impacts. This can come unstuck when disasters occur outside what has been predicted and planned for. Transforming Institutions for Climate Extremes is a response to this problem. It responds to the call for new methods to improve community resilience and help communities improve disaster planning. It seeks to explore how prepared our communities, our decision-makers and decision-making processes are for the challenges of ‘new’ climate conditions. It will consider what institutional changes are needed to meet those challenges whilst ensuring community ownership.
Climate change in Anglesea? Anglesea lies in an area of southern Australia that will be affected by climate change in many ways. Climate models project that the most likely direct impacts will include changes to rainfall (drier but with more intense rainfall events), changes in temperature (warmer with more heatwaves), increasing acidity of oceans and rising sea levels. In-turn, these impacts are expected to affect a whole range of factors including increases in coastal erosion and days of extreme fire danger to increased risk of heat-stroke and changes to when plants flower and birds migrate. Climate Change is the effect of heat from the sun being trapped in the Earth’s atmosphere by gases produced by human activity. While some of these gases (like carbon dioxide) are found naturally in the atmosphere, as we increase their concentration above natural levels, they trap more heat from the sun – a bit like an insulation blanket.

From the Infographic ‘Soil to Sky: of agroecology versus industrial agriculture’ by The Christensen Fund
In order to feed our world without destroying it, an holistic type of agriculture is needed, and we have a choice. Here we compare the current high-input industrial system with a renewed vision for agriculture: the agroecolocial system. […]
Agroecological strategies can better feed the world, fight climate change and poverty, and protect soil and water while maintaining healthy, liveable communities and local economies. Industrial agriculture contributes to climate change, malnutrition and ecosystem degradation around the planet. It has not delivered on its promise to feed the world.

An innovative renewable energy project is set to transform Tokelau and lead the world in transitioning from dependence on fossil-fuels to renewable energy.
With global attention focused on the effects of climate change and the international price of oil, it may come as a surprise that the tiny nation of Tokelau, comprising three remote atolls midway between New Zealand and Hawai’i, is moving to the forefront of the debate by installing renewable energy systems that will dramatically slash its reliance on imported fossil fuels. Undertaking a project of this scale on all three atolls is no mean feat. The closest atoll is around 500km north of Samoa; there are no airstrips or wharves, and the only access is a long boat trip from Samoa that ends outside the reefs, where a landing barge takes passengers and equipment to shore. Offloading goods in the swell is challenging. However, soon the job will become easier since almost 2,000 barrels of diesel a year will no longer be required to generate electricity.
Developing renewable energy projects in the Pacific brings unique challenges. Systems and components must be designed to withstand harsh tropical and marine environments, strong winds, high temperatures, and a corrosive salt-laden atmosphere. Unlike in New Zealand, where if a part breaks or needs replacing it is possible to replace easily, in Tokelau the systems and components must be designed to promote robustness and longevity, because transport is infrequent and challenging. And yet by the end of 2012 Tokelau expects to switch off its generators and begin to use an indigenous resource it has plenty of – sunlight.
Tokelau’s 1,411 residents are New Zealand citizens, and New Zealand is advancing $7 million to the Government of Tokelau to install the renewable energy systems that will help achieve its long-term goals of energy independence and reducing reliance on expensive imported diesel, which will put Tokelau at the forefront of global climate change mitigation efforts.
The energy crisis in the Pacific is not confined to Tokelau. Most Pacific Island nations are highly dependent on imported fossil fuels to meet energy needs, and are vulnerable to international price fluctuations and escalating fuel costs. Almost every aspect of Pacific economies is underpinned by imported fossil fuels, and the increasing cost of diesel results in extremely high costs of electricity for households and businesses. In many cases, the cost of importing fuel is many times higher than all export earnings combined, so Tokelau’s, and the Pacific’s, dependence on diesel is bad for the economy as well as the environment. […]
“This project is unique and has the potential to demonstrate what can be achieved through the perseverance and hard work by the Government of Tokelau,” adds Joseph Mayhew, Development Manager Energy in the New Zealand Aid Programme. “Photovoltaics are a mature, reliable off-the-shelf technology that has been proven for years. Given the high cost of diesel, renewable energy should not be seen as an ‘alternative’ source of energy, but rather an essential key to unlocking the Pacific’s potential.”

From “The High School Curriculum Every Urban Planner Wishes They’d Had” by Nate Berg:
City Semester is an immersive, city-focused course that combines classwork and field studies for juniors at Fieldston. It’s like other semester away programs run by the school, but instead of sending kids out to the Rocky Mountains or the Maine coast, students in the City Semester program turn their attention to their own neighborhood and city. Meyers has compiled a broad range of teachers from the school to participate, including teachers focusing on history, ethics, language, theater, literature, film, photography and music.
The program is divided into four main sections: sustainability, immigration and difference, power and conflict, and neighborhood and community renewal. This last section is centered around the Bronx River, located a couple miles from the school.
“We wanted to talk about neighborhood formation, and chronologically to talk about the recovery of the Bronx,” Meyers says. “We use the Bronx River as a means of discussing both human and non-human communities.”
One of the main parts of this section of the program consists of a two-day canoe trip down the river. The students collect scientific data about the water and the ecology and make presentations about both the history of the neighborhoods and the development of the river habitats. Meyers says this approach pulls in what the students are learning and relates it to things they see in their day-to-day experiences and the neighborhoods around them.
“Adolescents are at a place in their lives where understanding the relevance of what they’re learning can make an enormous difference in terms of their engagement,” Meyers says.
The program looks broadly at the city as a subject, even looking into the policies and politics that are driving change in New York. Meyers took the class to meet with officials from the city’s Department of Transportation to hear about the planning and implementation of bike lanes throughout the city. Then they rented bikes and rode the lanes. Meyers says this hands-on approach helps students to see the various ways what they’re learning can be applied in real-life situations.
And if delving into city politics isn’t enough to add a little more stress to high schoolers’ lives, one of the sections of the course had students role-playing and problem-solving their way through some not-too-far-off disaster scenarios brought on as a result of climate change. Rising sea levels create a flood in lower Manhattan that causes a blackout, in this scenario. During the power outage, a rumored hostage situation at the United Nations causes the whole subway system to shut down. Students had to imagine they were stuck in their school for 3 days – and to cope with all the logistical and psychological impacts such a situation would cause. They even engaged in community design charrettes to come up with feasible retrofit ideas that can help communities handle the potential threats they’ll face as the climate continues to change.
This section of the course was taught earlier this year by Alec Appelbaum, a journalist who’s covered urban planning for years. He says that high schoolers are maybe the ideal audience for this sort of lesson.
“They’re going to be living with the consequences of the misdirected debate that’s gone on about climate change,” says Appelbaum. “The carbon overload in the atmosphere is something that young people didn’t particularly cause and will have to survive.”
