Nation banks on green evolution

China's rapid transition to a green economy will be a boom both to its domestic market and the global economy, especially renewable energy industry, leading experts have said.

Commitment to developing a sustainable economy, emphasizing domestic consumption, and putting a green economy at the heart of the planning process already form the basis of China's ongoing 12th Five-Year Plan (2011-15).

"We definitely need China to succeed if the world is to succeed. Whatever China does will have global repercussions because a lot of the world's manufacturing is going on there," said Nis Hoeyrup Christensen, advisor on Chinese affairs at the Confederation of Danish Industry (CDI), and researcher in China's renewable energy sector at Copenhagen Business School.

He added that a green transition in China's manufacturing model will have especial relevance where it concerns production for the domestic market, "because that amounts to a lot of economic activity."

The UN's Environment Program defines the green economy as one where "growth in income and employment should be driven by public and private investments that reduce carbon emissions and pollution, enhance energy and resource efficiency, and prevent the loss of biodiversity and ecosystem services."

For its part, China is making a green refurbishment of its economy under a number of key headings defined in its 12th Five-Year Plan. These include that value-added output of emerging strategic industries will account for eight percent of gross domestic product (GDP), and that the country's manufacturing base in coastal regions will transit to high-end manufacturing, services and research and development.

Keystones in China's greening process include replacing coal-fired plants with those run on renewable sources like bio-mass, wind energy and solar power. Other areas involve better insulation of homes and offices to cut heating bills, combined urban heating and power networks, more recycling, improving energy-efficiency of production facilities, and developing alternative-fuel cars.

In fact, China is now the world's largest maker of wind turbines and solar panels, and its largest market for wind power. Moreover, the Chinese government says it plans to increase the share of non fossil-fuel based energy in the country's total energy consumption to 11.4 percent in 2015, up from 8.3 percent in 2010.

Green model

Denmark and its Nordic neighbors, who have been first-movers in the global green growth arena, could stand to benefit commercially from China's rapid green transition.

"I believe a more sustainable growth in China can turn out to be an advantage to Danish companies because of the technologies and solutions we have developed in our effort to create a green economy," said CEO of the CDI, Karsten Dybvad.

According to the CDI, the Danish economy has grown 78 percent since 1980, while keeping energy consumption more or less constant and slashing carbon dioxide (CO2) emissions, owing largely to technological developments in renewable energy and energy-saving.

The Danish or Nordic model of green development can be adopted in emerging economies as well, as long as they are scaled-up and adapted to fit local needs, experts say.

In fact, technology adoption and transfer would likely see Nordic technology and energy firms work even more closely with Chinese partners so as to better understand and respond to the needs of China's green market, Christensen said.

New chances

"China is at a crucial stage where the tracks will be laid out for the future direction of welfare policies and economic restructuring," Dybvad said, referring to China's move away from export-led growth and towards greater domestic consumption.

The social impact of re-balancing can perhaps be felt most palpably in the way China expects to care for its rapidly-aging population. According to Chinese official data, the country's elderly population equaled 185 million persons at the end of 2011, and is expected to be 221 million before 2015.

"Danish politicians have talked about exporting our welfare technology for a long time. This means equipment for old people's homes and hospitals, and tools which makes life easier for the elderly and for those who work with them," said Christina Boutrup, author of "China Sweet and Sour", a book on Danish companies' experiences in China.

"While this was just a dream scenario for Danish exporters in the past, China's move towards sustainability means the dream can now be realized," she added, pointing to this burgeoning area of business collaboration.

Although Danish companies can face "fierce competition from local players" when marketing welfare or energy technologies in China, Boutrup believes they hold a competitive edge as they can meet China's increasingly tighter environmental regulations, "even if they are more expensive."

Whatever the specific, future investment areas, companies will need a stable market with clear policy indicators of how best they can deploy their resources over time.

Given the Chinese government's grip on macroeconomic policy, Christensen believes these factors already exist in China and are among the stepping-stones to its green transition.

"If investors are going to put money into establishing a new technology or company, they need to be sure there is a market. In China, there is a market and a clear horizon, which the Chinese government is pretty good at showing, as it puts up both short-and-long term economic goals," he said.

SOLAR COOKING

Solar Household Energy (SHE) strives to unleash the potential of solar cooking to improve social, economic and environmental conditions in sun-rich areas around the world.

Over half the world's population currently relies on wood, charcoal or other biomass for daily cooking, leading to respiratory diseases, economic hardship, environmental degradation, and carbon emissions. Solar cooking with modern solar ovens such as the "HotPot" developed by SHE, when included as part of an integrated cooking solution, offers a practical, affordable, and sustainable alternative. Since 1998, Solar Household Energy has worked with governments, non-governmental organizations and the private sector to promote solar cooking and introduce it in developing countries through projects that distribute solar ovens and provide training for users.

We invite you to join us today in our efforts to spread the news about solar cooking and get it to those who can benefit from it most.

SOLAR COOKING NEWS:

• Solar cooking for the Haitian/Dominican border SHE has recently partnered with The Nature Conservancy to introduce solar cooking in Tilori, Haiti near the Dominican border as part of a larger program aimed at reforesting areas denuded for charcoal production and fuelwood for cooking. SHE combined Global Sun Ovens manufactured locally in the Dominican Republic by El Fuego del Sol with fuel efficient Envirofit stoves to offer a 24/7 integrated cooking solution for this community. Training sessions and follow-up were provided to the participants to help them learn how to use their new cookstoves.
• More HotPots for Sudanese refugees in Chad After a few months of solar cooking in the Gaga refugee camp in Chad, the Sudanese refuee recipients of HotPots distributed by Solar Household Energy at the request of U.N. High Commissioner for Refugees (UNHCR) were relieved to have an alternative to having to purchase fuelwood or risk the dangers of collecting it outside the camp. They said they wished that every woman in Gaga could have a solar oven. While not yet a reality for all 20,000 residents, SHE is now partnering withAfricare and UNHCR to distribute HotPots and providing training and follow-up for an additional 200 households in the camp.
• Solar-fried Chicken in the Dominican Republic: Solar Household Energy has joined with a new partner, Grupo Jaragua, to distribute solar ovens in the Dominican Republic and Haiti, in order to reduce the use of wood and charcoal for cooking fires that has seriously damaged the forest cover of the island shared by these countries. DR non-profit organization, Grupo Jaragua (GJ), provides solar cooked lunches everyday at its community center in Oviedo, demonstrating how easy and tasty solar cooking can be. GJ’s chief solar chef and trainer, Olga, has even devised a method for a healthier, solar-cooked version the fried chicken dish that is the local favorite.

New Dimension for Solar Energy: Innovative 3-D Designs More Than Double the Solar Power Generated Per Area

Intensive research around the world has focused on improving the performance of solar photovoltaic cells and bringing down their cost. But very little attention has been paid to the best ways of arranging those cells, which are typically placed flat on a rooftop or other surface, or sometimes attached to motorized structures that keep the cells pointed toward the sun as it crosses the sky.

Now, a team of MIT researchers has come up with a very different approach: building cubes or towers that extend the solar cells upward in three-dimensional configurations. Amazingly, the results from the structures they've tested show power output ranging from double to more than 20 times that of fixed flat panels with the same base area.

The biggest boosts in power were seen in the situations where improvements are most needed: in locations far from the equator, in winter months and on cloudier days. The new findings, based on both computer modeling and outdoor testing of real modules, have been published in the journal Energy and Environmental Science.

"I think this concept could become an important part of the future of photovoltaics," says the paper's senior author, Jeffrey Grossman, the Carl Richard Soderberg Career Development Associate Professor of Power Engineering at MIT.

The MIT team initially used a computer algorithm to explore an enormous variety of possible configurations, and developed analytic software that can test any given configuration under a whole range of latitudes, seasons and weather. Then, to confirm their model's predictions, they built and tested three different arrangements of solar cells on the roof of an MIT laboratory building for several weeks.

While the cost of a given amount of energy generated by such 3-D modules exceeds that of ordinary flat panels, the expense is partially balanced by a much higher energy output for a given footprint, as well as much more uniform power output over the course of a day, over the seasons of the year, and in the face of blockage from clouds or shadows. These improvements make power output more predictable and uniform, which could make integration with the power grid easier than with conventional systems, the authors say.

The basic physical reason for the improvement in power output -- and for the more uniform output over time -- is that the 3-D structures' vertical surfaces can collect much more sunlight during mornings, evenings and winters, when the sun is closer to the horizon, says co-author Marco Bernardi, a graduate student in MIT's Department of Materials Science and Engineering (DMSE).

The time is ripe for such an innovation, Grossman adds, because solar cells have become less expensive than accompanying support structures, wiring and installation. As the cost of the cells themselves continues to decline more quickly than these other costs, they say, the advantages of 3-D systems will grow accordingly.

"Even 10 years ago, this idea wouldn't have been economically justified because the modules cost so much," Grossman says. But now, he adds, "the cost for silicon cells is a fraction of the total cost, a trend that will continue downward in the near future." Currently, up to 65 percent of the cost of photovoltaic (PV) energy is associated with installation, permission for use of land and other components besides the cells themselves.

Although computer modeling by Grossman and his colleagues showed that the biggest advantage would come from complex shapes -- such as a cube where each face is dimpled inward -- these would be difficult to manufacture, says co-author Nicola Ferralis, a research scientist in DMSE. The algorithms can also be used to optimize and simplify shapes with little loss of energy. It turns out the difference in power output between such optimized shapes and a simpler cube is only about 10 to 15 percent -- a difference that is dwarfed by the greatly improved performance of 3-D shapes in general, he says. The team analyzed both simpler cubic and more complex accordion-like shapes in their rooftop experimental tests.

At first, the researchers were distressed when almost two weeks went by without a clear, sunny day for their tests. But then, looking at the data, they realized they had learned important lessons from the cloudy days, which showed a huge improvement in power output over conventional flat panels.

For an accordion-like tower -- the tallest structure the team tested -- the idea was to simulate a tower that "you could ship flat, and then could unfold at the site," Grossman says. Such a tower could be installed in a parking lot to provide a charging station for electric vehicles, he says.

So far, the team has modeled individual 3-D modules. A next step is to study a collection of such towers, accounting for the shadows that one tower would cast on others at different times of day. In general, 3-D shapes could have a big advantage in any location where space is limited, such as flat-rooftop installations or in urban environments, they say. Such shapes could also be used in larger-scale applications, such as solar farms, once shading effects between towers are carefully minimized.

A few other efforts -- including even a middle-school science-fair project last year -- have attempted 3-D arrangements of solar cells. But, Grossman says, "our study is different in nature, since it is the first to approach the problem with a systematic and predictive analysis."

David Gracias, an associate professor of chemical and biomolecular engineering at Johns Hopkins University who was not involved in this research, says that Grossman and his team "have demonstrated theoretical and proof-of-concept evidence that 3-D photovoltaic elements could provide significant benefits in terms of capturing light at different angles. The challenge, however, is to mass produce these elements in a cost-effective manner."
