PV 2008

2009-10-30T13:55:00.007+05:30

Here is an excellent report on the global status of PV, as of August 2009, from the EU Joint Research Centre, Renewable Energy Unit (part of the European Commission):

http://re.jrc.ec.europa.eu/refsys/pdf/PV-Report2009.pdf

Things are looking bright: in 2008 between 7 GW and 8 GW of solar PV (photovoltaic) cells was produced worldwide, nearly double the amount in 2007!

Since 2003, total PV production increased almost 10 fold with annual growth rates between 40% and 80%, whereas the thin film segment – starting from a very low level – grew in average by over 90%.

It seems we're finally having 'take off' and starting to move away from the fossils!

Barefoot Women Solar Engineers of Africa Are Finalists in the World Challenge!

2009-09-26T22:41:00.003+05:30

The Barefoot energy venture benefiting African communities, theBarefoot Women Solar Engineers of Africa, has been selected as a finalist in World Challenge 09, the worldwide competition seeking to identify and reward projects and businesses which bring economic, social and environmental benefits to local communities through grassroots solutions.

The Barefoot Women Solar Engineers of Africa aims to improve the lives of people living away from any electricity supply in rural parts of Africa - giving them clean, renewable and low cost sources of energy.

Since 2005, 81 women, often illiterate, have trained as solar engineers at the Barefoot College in India learning how to fabricate, install and maintain solar lighting systems in their villages in Africa. Transforming the lives of over 2000 families, they are helping to reduce the impact of forest depletion in local communities and their dependence on kerosene and diesel.

The World Challenge

LED vs CFL

2009-09-23T15:14:00.001+05:30

"Only 2% of total energy consumed by LED-based lamps is used in their production."
When trying to determine the greenest option among products, it is important to take into account the whole life-cycle of the thing; the manufacturing process, how it is used, and the disposal at the end of its life. The U.S. Department of Energy has already released a few life-cycle assessments (LCA) of LED lights (see here and herefor a Carnegie Mellon study), and LED maker Osram has just released a new LCA study conducted by the Siemens Corporate Technology Centre for Eco Innovations. Their conclusions are pretty interesting...

Solar-powered appliances hogs limelight

2009-09-17T11:51:00.000+05:30

Lot of takers: Solar water heaters are becoming a more common feature on household terraces in Puducherry.

PUDUCHERRY: Increased awareness of the benefits of using renewable energy has resulted in solar water heaters and lanterns finding a lot of takers in Puducherry. The subsidies available for renewable energy appliances is an added incentive.

According to officials of the Renewable Energy Agency of Puducherry (REAP), solar water heaters of a total daily capacity of 37,125 litres have been installed in Puducherry, from 2005 to 2009.

At least ten applications for solar water heater subsidies are received every month, an official added.

Although these heaters are expensive, with a 100-litre capacity heater costing around Rs. 18,500, REAP provides a subsidy of Rs. 3000 per heater, upon producing proof of purchase along with the application.

Subsidies are granted to dealers of these appliances approved by the Ministry of New and Renewable Energy (MNRE).

People, especially fishermen have evinced a lot of interest in solar lanterns, officials say. Between 2001 and 2009, over 507 lanterns, each costing around Rs. 4,000, have been given a subsidy of Rs. 1,550 by REAP.

In recent years, fishermen from Mahe have been availing around 100 subsidies a year, officials revealed.

Apart from heaters and lanterns, REAP has been providing subsidies for a host of other appliances such as solar cookers, water pumps and solar industrial air-heating systems, in order to encourage people to decrease their dependence on polluting fuels.

Subsidies are also provided for complete solar ‘homelighting’ systems, which consist of a 37-watt solar panel, charge controller, battery and two Compact Fluorescent Lamps (CFLs).

Appearance in public sphere

Solar-powered devices have made an appearance in the public sphere as well. The solar powered street lamps have already become a notable feature on Puducherry’s beach. Institutions and non-commercial outfits receive a subsidy of Rs. 9,600 from the MNRE on these streetlights. 417 such streetlights have been installed in the Union Territory.

The government has also set an example for the public, with the installation of a 25-kilowatt solar power plant, at the Secretariat building in 2003-04.

Officials of REAP also say that the scheme of providing two CFLs to ration card holders at the price of one, has also met with very encouraging response. With the price coming down, response is bound to get better, the official added.

The agency, which is the State Nodal Agency for the Bureau of Energy Efficiency and MNRE is currently drawing out its budget allocation and new schemes.

EASE

2009-08-05T01:23:00.002+05:30

EASE stands for Enabling Access to Sustainable Energy. The EASE partnership aims to bring modern energy products to the rural poor in developing countries, by facilitating the upscaling processes in the rural energy sector and local energy markets.

EASE partners do not believe that the energy problems of the poor can be resolved with a mere technological breakthrough or through large scale financial support.

Instead, EASE projects start by better understanding the realities of the energy needs of the poor, and their local energy markets of shopkeepers, technicians, promoters and (micro)financiers.

By presenting the bottlenecks in these local markets, EASE partners design and implement projects with a lasting impact.

The vast potential of energy efficiency in India

2009-08-05T01:16:00.002+05:30

Five times cheaper than nuclear power

A recent study by the World Resources Institute (WRI) calculated that India could reduce its annual electricity usage by 183.5 billion kWh by investing US$ 10 billion in energy efficiency improvements.

India’s energy demand is expected to more than double by 2030. The country is consequently in need of a huge amount of new power generation capacity. Considering the figures of the WRI, the cheapest generating capacity for India will no doubt be energy savings.

The Sixth Revolution: The Coming of Cleantech

2009-07-24T13:58:00.003+05:30

Technology revolutions occur about every 50 years. The current IT age should give way to the leadership of cleantech as the energy infrastructure moves back to renewables. Investors are likely to be rewarded in the irruption phase, which we see accelerating in 2010-11 after current funding problems end.

The Indian PV plan

2009-07-15T02:47:00.003+05:30

As part of the National Action Plan on Climate Change, the Indian government has announced this month its plans to install 20GW of solar generation capacity by 2020, 100GW by 2030 and 200GW by 2050.

This plan will be launched in three phases:

During phase 1 from 2009-2012, India will deploy 100MW of solar PV on public sector buildings, promote utility-scale PV projects and set up local solar manufacturing parks. The plan envisions 1GW installed solar generation capacity by 2012, up from almost nothing in 2008. During phase 2 from 2013-2017, the government plans an installed capacity of 6-7GW by commercial operations of various pilot programs and during phase 3, government expects rapid scale-up of solar programs with minimal subsidies and to reach 20GW capacity in 2020 with 3GW rooftop PV installed on 1 million rooftops.

Three types of incentives are expected: Feed-in-tariffs for 20 years set annually and without official cap, 10 year tax holiday and customs and excise duty exemptions on capital equipment and other critical materials. Additionally, the government plans to introduce National Solar RPS - whereby states would be required to generate 1-3% of electricity from solar resources by 2017. In order to facilitate the creation of solar facilities, additional policies are expected to be introduced.

The Indian PV Sector

The electricity consumption per capita in India is expected to increase from 660 kWh currently to over 2,000 kWh by 2032. India's per capita consumption is about 7% of the OECD countries and 20-25% of the world average. Furthermore, India's grid connected capacity is estimated to grow from 146GW in 2008 to over 460GW by 2030. Although wind currently dominates renewable energy generation in India, solar PV has the potential to outpace wind generation given attractive solar conditions. Several studies show that approximately 0.5% of India's land area would be sufficient to meet all electricity needs using solar PV technology by 2030.

Approximately 70% of India's population lives in rural areas and more than 450 million of the Indian population have no access to grid electricity. Approximately 80,000 villages are not even connected to the grid. The Indian government spends approximately $2-4 billion annually to subsidize the price of kerosene, which is the primary fuel used for electrification of rural India. Therefore, PV has also a major card to play in this market. In addition, solar PV is also ideally suited for the 21 million Indian irrigation pump market. Electricity consumption by the irrigation pump sector is estimated to account for between 10-15% of India's total consumption.

Finally, there is significant potential for solar PV to replace estimated 20-25GW of captive power generation, which is currently supported mostly with diesel power generators running at costs comparable to solar PV costs today.

Renewables Global Status Report

2009-05-19T08:03:00.000+05:30

Transformation Continues Despite Economic Slowdown

This fourth edition of REN21’s renewable energy report comes in the midst of an historic and global economic crisis,” says Mohamed El-Ashry, chairman of REN21. Although the future is unclear, he says, “there is much in the report for optimism.”

Global power capacity from new renewable energy sources (excluding large hydro) reached 280,000 megawatts (MW) in 2008 – a 16 percent rise from the 240,000 MW in 2007 and nearly three times the capacity of the United States nuclear sector.

Solar heating capacity increased by 15 percent to 145 gigawatts-thermal (GWth), while biodiesel and ethanol production both increased by 34 percent. More renewable energy than conventional power capacity was added in both the European Union and United States for the first time ever.

“The recent growth of the sector has surpassed all predictions, even those made by the industry itself,” says El-Ashry, adding that much of this growth was due to more favourable policies amidst increasing concerns about climate change and energy security.

Energy Efficiency Could Save India 183.5 Billion kWh

2009-05-01T15:48:00.000+05:30

With an investment of US $10 billion dollars in energy efficiency improvements, India's economy would benefit from its potentially vast annual energy savings of 183.5 billion kilowatt hours, according to a new report from the World Resources Institute (WRI).

“India’s energy demand is expected to more than double by 2030. There is a dramatic need for domestic and international energy efficiency technology providers, service providers, and equipment manufacturers to develop innovative ways to conserve energy,” said Robin Murphy, WRI vice president of external relations.

A key element in realizing this potential is the energy service company (or ESCO) sub-sector. ESCOs operate on the basis of energy-performance contracts, wherein revenue is earned based on the amount of energy cost savings produced. In India, the ESCO industry had an annual growth rate of 96 percent from 2002 to 2007 and is estimated to have grown by an additional 62 percent in 2008, according to financial information provided by these companies to WRI.

WRI’s report, Powering Up: The Investment Potential of Energy Service Companies in India is being released as part of the New Ventures India Investor Meet, a gathering of leading investors and other stakeholders interested in the intersection of environment and enterprise.

Solar Water Heating is Best Use of Solar Power, Indian Scientists Assert

2009-04-08T12:07:00.000+05:30

A quick search on TreeHugger shows that 'solar power' most often occurs in connection with producing electricity and only secondarily in connection with solar water heaters. That's unfortunate, according to scientists at the Dr Panjabrao Deshmukh Agricultural University in India, because using the sun's power to heat water is a far more efficient process and offers a much quicker return on investment:

According to their analysis, published in the International Journal of Global Energy, as the payback time for a solar water heating system is about two years (with a lifespan of 20), this is a far more cost-effective use of solar energy in the developing world than using it to generate electricity. Compared to electrically heated water, solar water heating is 57% of the internal rate of return, the scientists found:

Solar energy is the only renewable energy source that has wide range of uses with commercial viability. The use of solar energy for thermal purposes is the most cost-effective way of utilizing the resource.

Will the Children of Today Be Living in a World Powered by Renewable Energy by 2050?

2009-02-04T17:50:00.001+05:30

The world needs a one-off switch-over to renewable energy -- and this could be largely accomplished in just forty years time, slashing energy costs and greenhouse gases while allowing healthy economic growth, experts say.

The study estimates that 56% of primary energy demand will be covered by renewable energy sources by 2050 while energy efficiency potentials will have been largely exploited. As a result, primary energy demand will stabilize at 2060 levels.

By 2050, 80 percent of the world's electricity could be coming from renewable energy sources provided efforts are made, in parallel, to improve energy efficiency, according to a study by the German Aerospace Center (DLR). That means, the children of today might well grow up to experience a world where the energy they use comes almost entirely from the sun, wind, sea and biomass.

By 2090, the shift to renewable energy around the world could be almost 99 percent completed reducing pressure on the environment and laying the foundations for a new era of prosperity based on green energy.

The Energy [R]evolution Report commissioned by Greenpeace International and the European Renewable Energy Council (EREC) also outlines a scenario that would see a fairer redistribution of the burden of cutting greenhouses around the globe. Under the DLR plan, America and Western Europe would decrease their high per capita energy use by switching over to renewable energy and introducing energy saving measures as soon as possible while countries such as China and India would initially slow down their increase in energy demand before starting the switch-over to green energy.

Technologies like dye-sensitive solar cells and thin-film photovoltaics are being developed rapidly and present a huge potential for cost reduction. Also, major innovations in geothermal and ocean wave technology can be expected as research in these areas increases in the future.

"Smart power" will improve the efficiency of buildings and transport, and the DLR predicts that the city centers of the future, for example, could be producing power and heat as well as consuming it. The buildings will have photovoltaic facades not only for energy production but also as an element of architectural design. Solar thermal collectors are set to produce hot water in the networked cities of tomorrow where energy comes from a variety of sources, large and small in scale.

In addition, the DLR predicts that the energy supply system of the future will move from the large and centralized one of today's world towards a much more decentralized one, based on a wide mix of energy sources. These will be tailored to the geography of a particular region to optimize its specific and unique potential.

According to the DLR, solar photovoltaics, followed by wind power, concentrated solar power and geothermal, have the highest potential for development from technologies currently available.

To study notes huge amounts of energy currently wasted from cooling towers could be harnessed for co-generation.

A further piece in the puzzle to create a world powered by renewable energy is to make the transport sector more efficient by switching over to electric vehicles powered by renewable energy sources and also by building up public transport system.

Freeplay Energy

2008-12-25T02:22:00.003+05:30

Freeplay Energy has been developing some great consumer products over the years, such as the Lifeline Radio, Jonta “human-powered” Flashlight, and the Indigo LED Lantern. But there is an offshoot of Freeplay we have yet to discuss, which is the non-profit Freeplay Foundation. With the help of the Lemelson Foundation, and green celebrity, Tom Hanks, Freeplay has been working to bring clean and renewable energy lanterns to Rwanda.

The Lifelights will replace the old, polluting, and dangerous kerosene lights currently being used in Rwanda. Compared to the consumer version of the Indigo Lantern, the ones that will be sent to Rwanda this February of 2009 are far more durable (able to withstand extreme weather and environmental conditions) and can be used to light up a larger area for longer periods of time.

The technology behind the Lifelight is primarily LEDs (Light Emitting Diodes), which provide an amazing amount of light for their size, efficiency rating, and non-toxic nature. Like Freeplays consumer brand of products, this lantern can be powered/charged by either sunlight or their own patented “wind-up” technology, which is thankfully far beyond most other “shake” flashlights on the market today.

The Lifelights are designed to be almost indestructible and to last for years with minimal maintenance and cost to the owner.

Konarka with 1 GW thin-film manufacturing facility

2008-10-24T05:29:00.003+05:30

Konarka Technologies Inc. has opened what it claims to be the largest roll-to-roll flexible thin film solar manufacturing facility in the world, in New Bedford, Massachusetts, USA.

The rationale is to prepare for the commercialisation and mass production of Konarka’s Power Plastic, a thin, lightweight, and “very flexible” polymer-based organic photovoltaic (OPV) thin film solar material. The 250,000 ft² building was previously the location for Polariod Corporation’s advanced printing technologies.

“This facility has state-of-the-art printing capabilities that are ready for full operation, with the future potential to produce over a gigawatt of flexible plastic solar modules per year,” says Howard Berke, Executive Chairman and Co-Founder of Konarka.

“Our technical leadership and innovation in flexible thin film solar, along with this facility’s capabilities of producing in excess of 10 million square meters of material per year, will allow us to produce Power Plastic for indoor, portable, outdoor and building integrated applications.”

Explosive Growth Reshuffles Top 10 Solar Ranking

2008-09-17T14:25:00.002+05:30

The explosion of photovoltaics production across the globe completely reshuffled the top companies in Nomura Securities' annual ranking of the leading companies, knocking long established Japanese players out of the top spots and putting four Asian suppliers in the Top 10. Japan's leading solar companies outline their strategies for this changing market in this report from SST partner Nikkei Microdevices.

Fast growing Q-Cells AG became the world's largest solar cell maker in 2007, producing nearly 400 megawatts (MW) worth of product. Longtime solar industry leader Sharp found itself in second place as production slipped to roughly 370 MW, which the company blamed on a constrained supply of silicon. China's Suntech was close behind the leaders with more than 300 MW output, pushing Kyocera and its 200 MW to a distant third.

1.6 Percent

2008-09-12T16:45:00.003+05:30

On the face of it, the Indian wind energy sector is booming. Installed wind power capacity has increased six-fold in the last seven years—from 1,338 mw in 2000-01 to 8,754 mw in 2007-08. In the last three years alone, about 5,150 mw has been added. As on March 31 this year, wind power accounted for 6.1 per cent of the total installed capacity to generate power in India.

The biggest challenge for the wind-power industry in India is to come to terms with the need to generate more power and to accurately account for it.
mnre collates data on the installed wind energy capacity, but most experts believe its data on wind power generation is questionable. The Central Electricity Authority does not collect data on wind power generation either. From the data mnre provides, adding capacity has not converted to actual power generation.

The average plant load factor, getting better, is still around 15 per cent. As a result, even as wind power generation has increased from 1,577 million units (mu) in 2000-2001 to 11,413 mu in 2007-2008, it accounts for a meagre 1.6 per cent of all power generated.

Moreover, industry is worried about stagnation in installation. Write Mahesh Vipradas and Niraj Kumar of the Indian Wind Energy Association, in their recent assessment of the sector: “The annual installation in 2007-08 is the lowest in the last three years, making us ask: is this the beginning of the end of the Indian wind success story?” They believe policy measures enacted in the past have had their run of success. Now, more steps are needed to re-energise the sector.

India Builds Solar: A BIPV First

2008-09-10T21:51:00.002+05:30

India's first green housing project facilitated with building-integrated solar power has been developed in a new district of Kolkata. Both environmentally and economically attractive, this project acts as a trailblazer for the rapidly developing country. Jaideep Malaviya reports.

The burden of combating global warming is not restricted to developed countries and many developing countries have shown their commitment to moving towards a more sustainable, low-carbon economy.

A good example of this type of commitment comes from India's West Bengal region, where the country's first housing complex using roof-integrated photovoltaics has recently been completed.

The policy behind the Rabi Rashmi Abasan project, which in the local Bengali language means ‘solar ray-based dwelling', was the brainchild of S. P. Gon Choudhary, managing director of the West Bengal Green Energy Development Corporation Limited (WBGEDCL), a state government-backed renewable energy undertaking.

Algae: Biofuel of the Future?

2008-09-02T12:33:00.001+05:30

In the world of alternative fuels, there may be nothing greener than pond scum. Algae are tiny biological factories that use photosynthesis to transform carbon dioxide and sunlight into energy so efficiently that they can double their weight several times a day.

As part of the photosynthesis process algae produce oil and can generate 15 times more oil per acre than other plants used for biofuels, such as corn and switchgrass. Algae can grow in salt water, freshwater or even contaminated water, at sea or in ponds, and on land not suitable for food production.

Silicon Rally

2008-09-01T17:45:00.000+05:30

FOR 40 years or so, the price of solar panels fell steadily, as volumes grew and technology improved. But in 2004 Germany enormously increased subsidies for solar power, prompting a surge in demand. The supply of pure silicon, the main component of most solar cells, did not keep pace. Its price rose from $25 a kilogram in 2003 to as much as $250 this year, abruptly halting the downward march in the price of panels. If making energy from sunlight is ever to become as cheap as burning fossil fuels, the price of silicon will have to fall.

Happily, it seems likely to do so soon. Silicon producers, whose biggest customers were always chipmakers, have been slow to cater to the solar industry. They were scarred by the memory of the technology bust of 2001, which had weighed them down with excess capacity, and so delayed expansion—despite the boom in solar. Moreover, it takes three years or so to get a new plant going, so new silicon supplies are only just beginning to materialise.

Creating Realistic Expectations for Renewable Energy

2008-08-22T13:08:00.002+05:30

It's a delicate time for the renewable energy industry. Now that the public eye is focused more intensely on clean energy technologies, there are a lot of high expectations about their potential. Properly educating consumers, investors and journalists about what each technology can realistically offer will be one of the most important factors in moving renewables forward, say industry professionals.

At the consumer level, that means encouraging buyers to do the necessary research about the product they're purchasing and the company they're working with. If buyers don't really know what they are getting, that could make for a less-than-satisfactory experience — or even worse, a situation where the customer gets scammed.

Indian Solar Loan Program Offers Access to Light

2008-08-13T17:34:00.002+05:30

If you live in a rural area of southern India, two lights can literally save your life.

Just ask Vinoj Kanaya, farmer of silkworms who lives outside a small village located 250 kilometers from the new Silicon Valley of Bangalore. Like many people in developing countries, Mr Kanaya wanted something better than burning wood, dung or kerosene for which he paid a higher proportion of his income than someone in a developed country.

After he installed two solar-powered lights with the help of a solar loan, Kanaya says attacks by deadly cobras have gone down because the snakes are scared off by the brighter solar light. The lights are much cheaper to run than those powered by kerosene and there are fewer accidents and burns with solar lights. Kanaya says that both his helpers and his silkworms work much better without the smoke and fumes of kerosene lamps.

An extra light or two that may not mean much to many in the developed world, but for Kanaya and thousands of others, they've brought safety, profits and better quality of life. For SELCO Vice President, Mr. Thomas Pullenkav, the equation is simple: "quality of light equals quality of life."

The economics of solar power

2008-08-11T11:00:00.001+05:30

Solar energy is becoming more economically attractive as technologies improve and the cost of electricity generated by fossil fuels rises.
By 2020, hundreds of billions of dollars of investment capital will probably boost global solar-generating capacity 20 to 40 times higher than its current level.
As the new sector takes shape, producers of solar components must drive their costs down, utilities must place big bets despite enormous technological uncertainty, and regulators must phase out subsidies with care.
The actions these players take will determine the solar sector’s scale, structure, and performance for years to come.

China 'leads the world' in renewable energy

2008-08-10T10:29:00.001+05:30

China is the world's leading producer of energy from renewable sources and is on the way to overtaking developed countries in creating clean technologies, according to a report by the Climate Group.

Published August 1st 2008, the group's report, China's Clean Revolution, shows that supportive government policies investing billions of dollars in energy efficiency and renewables are driving huge levels of innovation in China.

The Climate Group says that, despite its coal-dependent economy, China has become a world leader in the manufacture of solar photovoltaic technology - its six biggest solar companies have a combined value of over $15bn (£7.57bn). Around 820 megawatts of solar PV were produced in China in 2007, second only to Japan.

The country already leads the world in terms of installed renewable capacity at 152 gigawatts. In the next year, China will also become the world's leading exporter of wind turbines and it is also highly competitive in solar water heaters, energy efficient home appliances, and rechargeable batteries.

Solar Thermal Power Coming to a Boil

2008-07-22T11:07:00.002+05:30

After emerging in 2006 from 15 years of hibernation, the solar thermal power industry experienced a surge in 2007, with 100 megawatts of new capacity coming online worldwide. During the 1990s, cheap fossil fuels, combined with a loss of state and federal incentives, put a damper on solar thermal power development. However, recent increases in energy prices, escalating concerns about global climate change, and fresh economic incentives are renewing interest in this technology.

Considering that the energy in sunlight reaching the earth in just 70 minutes is equivalent to annual global energy consumption, the potential for solar power is virtually unlimited. With concentrating solar thermal power (CSP) capacity expected to double every 16 months over the next five years, worldwide installed CSP capacity will reach 6,400 megawatts in 2012—14 times the current capacity. (See data.)

Unlike solar photovoltaics (PVs), which use semiconductors to convert sunlight directly into electricity, CSP plants generate electricity using heat. Much like a magnifying glass, reflectors focus sunlight onto a fluid-filled vessel. The heat absorbed by the fluid is used to generate steam that drives a turbine to produce electricity. Power generation after sunset is possible by storing excess heat in large, insulated tanks filled with molten salt. Since CSP plants require high levels of direct solar radiation to operate efficiently, deserts make ideal locations.

Jatropha Production Expanded in India

2008-07-21T19:54:00.003+05:30

India is one of the world’s leading cultivators of jatropha as a feedstock for biodiesel, with over one million hectares planted to date. That figure is set to rise slightly on the news that Hindustan Petroleum and the Chhattisgarh Renewable Energy Development Agency (CREDA) are partnering to plant an additional 15,000 hectares.

Cleantech is reporting that though the exact financial terms of the deal have not been disclosed, Hindustan Petroleum will hold 74% of the joint venture and will received the entire harvest of jatropha seeds, which it will then refine into biodiesel for sale at its retail outlets across the state of Chhattisgarh. The land used for cultivation will be wastelands obtained by CREDA.

India has conducted a number of trials using Jatropha-based biodiesel on it public transport systems, both on major train routes and on public buses.

Ashden Awards 2008

2008-07-21T10:04:00.005+05:30

The Ashden Awards are given to visionaries in the developing world who are finding solutions to climate change and bringing real social and economic benefits to their local communities at a grass-roots level. In the past projects have shown how simple, innovative design, at a relatively small price can bring huge changes to large numbers of people in terms of health, education, and social welfare. This year the 7 finalists are no less inspiring.

In Western China, the Renewable Energy Development Project (REDP), has brought affordable, high-quality solar lighting to people who live in tents in rural areas. Since 2001, REDP has sold over 402,000 photovoltaic (PV) solar-home systems to yak and other herding communities in remote areas. Previously they relied on kerosene, butter lamps and candles for light. Now almost 1.44 million people who previously had little access to electricity have an improved quality of life through better light, communications and entertainment.

Thomas Edison on the sun

2008-01-17T22:57:00.002+05:30

"We are like tenant farmers chopping down the fence around our house for fuel when we should be using Nature's inexhaustible sources of energy-sun, wind and tide. I'd put my money on the sun and solar energy. What a source of power! I hope we don't have to wait until oil and coal run out before we tackle that.

"Thomas Alva Edison (1847-1931).
