Alternative Energy Argentina: Bringing Wind Power to Remote Areas

Max Seitz reports for the BBC that wind power is the most widespread renewable energy source in Argentina - and Patagonia in particular has extraordinary potential due to its strong and constant winds.

He travelled to southern Chubut province, about 890 miles south of Buenos Aires, where wind power is making life easier for a number of isolated communities

In the midst of a dark wilderness, wind-generated electricity is changing lives in the region, lighting homes and schools in remote areas.

"Patagonia provides ideal conditions, unique almost, for the development of wind power," explained Hector Mattio, Director of the Regional Centre for Wind Power (or Cree in Spanish).

"We get very strong sustained winds of 11 metres per second, while in Europe they usually only reach about nine," Mattio added.

Cree - funded by the Chubut government and located in the provincial capital Rawson, near Trelew - currently has many community projects on the go to install wind generators.

So far, more than 300 isolated rural villages in Chubut have received small wind turbines which provide them with light, communication and power for domestic electric appliances.

A 66-year-old Araucano Indian, Julian Ibanez, welcomed us to his stone-built house.

Julian owns horses and sheep but his prize possession is a three-blade, 12-metre high wind turbine with 600-watt power (the equivalent of 10 light bulbs). Like others in the region, he simply calls it the "windmill".

"They installed the windmill a while ago now and it's changed our lives. We didn't have electricity before, just a kerosene lamp and that was it; now we have light and we can listen to the radio."

Julian led me to a plain bedroom, where he had a fuse box attached to the wall and a 12-volt car battery, and explained how everything worked.

The wind turns the windmill blades and a cable takes the energy produced into the house. The fuse box controls the voltage and battery charge.

Marcos added that the electrical supply is constant - whether it comes directly from the generator or, when there is no wind, from what has been stored by the accumulator.

Some dwellings have installed an inverter, a gadget to transform a 12 volt output into 220 volts - ideal for domestic appliances.

Another inhabitant of the area, 30-year-old Adelino Cual, also an Araucano, had this to say: "We have electricity 24 hours a day, not just the little lamp we had before. We no longer have to buy kerosene or gas-oil. It works out cheaper for us."



The engineers had shown him how to work and maintain the generator and the fuse box: "They taught me, for example, how to change the fuses if they blow; I've changed them several times," he said.

And Marcos added that the idea is for those benefiting from the technology to be self-sufficient.

After visiting the hamlets around about, we made our way to the heart of Chacay Oeste, which comprises a dozen or so houses and a school-shelter which accommodates some 30 pupils from neighbouring settlements.

The school has been provided with six wind turbines, installed by Cree in the highest part of the town.

"They provide energy for our building, for the shelter and also the teachers' houses. During the school holidays, they are used to supply energy to the rest of the village".

Before turbines were installed, Chacay Oeste got its electricity from a petrol generator, the noise of which had become part of the landscape for the locals.

"The windmills have changed things a lot for the youngsters. Now they have access to computers, and teachers can educate them through television programmes."

"Now I feel I communicate more with other people. Not like before - we were a bit unsociable," Julian confessed after telling me that he regularly listens to the radio to find out what is going on, and that he really appreciates the Cree technicians' visits.

And at Cree they confirm that this is indeed what it is all about: The social impact the technology has had on the communities has helped to integrate them more.

Hurricane Wilma Power Outages Boost Solar Power in Florida

Florida Solar Energy Center

South Florida's Sun-Sentinel newspaper reports that Florida resident Pam Wall was able to relax while the rest of her neighbors were cloaked in darkness after Hurricane Wilma struck. The Fort Lauderdale resident still had all her modern conveniences -- working lights, TV, hairdryer, coffee pot and refrigerator -- all thanks to solar power.

Two solar-powered panels attached to the homemade sailboat docked in her back yard enabled Wall and her husband to enjoy all the noise-free, stress-free power they wanted while they waited almost three weeks for electricity to be restored to their house.

"We just lived on the boat and all the power we needed was from our solar panels," she said. "We didn't worry about fuel."

Wall is one of a small number of South Floridians who found solar power to be an effective alternative during times of disaster. The group's ranks are expected to grow, industry officials say, as residents realize how vulnerable they are to power outages and gas shortages each hurricane season. Also, new tax credits that go into affect on the first of January allow homeowners and businesses to deduct 30 percent of the cost of a solar-power system from their taxes, for a total credit of up to $2,000, according to the Energy Policy Act of 2005.

Instead of buying a gas generator this year in preparation for hurricane season, Dan Fieldman of Jupiter bought two solar panels for $683. After Wilma knocked out the electrical grid, he laid the panels out on his lawn, hooked them up to a car battery, attached a few small appliances and watched the World Series on TV as he checked his email.

"It was dead silent, it didn't stink up the place and I didn't have to worry about buying gas," he said. "I had a little color television and a laptop and a refrigerator. It was great."

There are drawbacks. Solar power is more expensive than regular electricity, needs sunshine to work and can be more difficult to set up.

Nonetheless, local governments are also getting in on the action, using solar-powered traffic signals and lights to make roads safer during outages. The city of Coral Springs used seven solar signals after the storm, and officials found them so successful they have ordered another four despite their hefty price tag of $10,000 each.

"They worked out wonderfully," said Police Chief Duncan Foster. "They have proved themselves in the man-hours we saved directing traffic. We didn't have to put an officer in those intersections and risk their safety."


Florida Solar Energy Center in Brevard, Florida

Jim Fenton, director of the Florida Solar Energy Center, the largest state-supported renewable energy research institute in the United States and a branch of the University of Central Florida, wants to take things a step further and lobby the state to install mobile solar-power systems at local schools that serve as hurricane shelters. That way, he said, the schools can save money on their energy bill during the year, have power if electricity is knocked out, and send out the mobile system after a storm if it is needed elsewhere.

For most, however, the advantage of solar energy during this year's outage was simply a surprise benefit to something they originally did for economic, environmental or practical reasons.

Tim Williamson, a Hollywood resident and pastor of Hollywood Hills Alliance Church, had a solar water heater installed at his home five years ago to save about $30 a month on his energy bill. It was such a luxury to have warm water after Wilma, he now says he would consider hooking up other solar-power systems.

"We were taking nice hot showers when everyone else was taking cold ones," Williamson said.

The main reason more people don't have a solar-power home is simple. It's pricey.

Diane Marshall of Key Largo spent about $24,000 to set up her solar-power home, which also purifies its own water and won her the 2005 "Green Building" Award from The Council for Sustainable Florida.

As a result, while there are tens of thousands of people with solar water heaters in the state, there are only a few hundred who have solar electric systems that power their homes, estimated Jim Dunlop, an engineer with the Florida Solar Energy Center.

Even with all that expense, there are technical challenges associated with using solar power during an outage, experts explain.

First off, there are two kinds of solar power: solar electric and solar thermal.

Solar-electric systems, also known as photovoltaic systems, use silicon cells on a solar panel to convert the sun's energy into direct current electricity. An inverter turns this electricity into power most appliances can use.

But to work at night and during periods of cloudiness, solar-electric homes need to incorporate a battery system that stores the solar power generated during daylight. Otherwise, they only work when the sun is shining.

Some choose to forgo such battery systems because they cost about 25 percent more, Dunlop said.

Solar water heaters, an example of a solar-thermal system, work much more simply by using the sun's energy to directly heat water. But they also have their quirks. For example, homeowners need to make sure they have a solar-powered water pump -- not an electric one -- as part of their solar water heater if they want hot water during a prolonged blackout.

Julie Joyce of Fort Lauderdale learned this the hard way when she lost hot water a few days after Wilma because her pump was electric. Two weeks into the outage, Joyce paid a company $640 to install a solar pump.

"Ahh, it was wonderful," she said, recalling her first hot shower, saying the price was worth it. "It's up there forever now."

Another concern: solar panels must be installed correctly so the panels don't fly off in a storm or become damaged.

Bone, the owner of a solar home on No Name Key, said the panels on his house did fine in the hurricane, but he has seen some homes where they have not. He said there are two ways to mount panels on roofs -- flush or, as was common in the 1980s before Hurricane Andrew, tilted to the south for maximum sun exposure. Tilted panels have a greater chance of catching wind and tearing off, he said. Most modern installations must meet strict building codes that certify they can withstand hurricane force winds.

Despite such drawbacks, those who have tried solar power say it is easy to get hooked on the silent, abundant energy source -- both during an outage and after.

"If I ever redo my house, I would put solar panels everywhere," said Wall, the solar sailboat owner. "You can use it all the time, not just during a hurricane."

Ecovillages, Watching TV, Saving Water and Changing Energy Consumption

One of the aims of the Alternative Energy Blog is to go beyond reporting the opening of the latest windfarm and explore our existing energy culture and how this culture can be changed. While the recent UK television series "No Waste Like Home" went into the homes of families which used several times the energy of the "average" family, the recent episode of the documentary series "30 days" from American documentary maker Morgan Spurlock (of "Supersize Me" fame) approached the issue by taking two "ravenous consumers of fossil fuels" and making them go cold turkey by taking them off-grid by living on the Dancing Rabbit Ecovillage, a commune "committed to radical environmental sustainability" in rural northeastern Missouri.

This approach was in my opinion a limited success. While it may have made for reasonably diverting television with one participant saying they couldn't live without their hair products and the other adopting the name "Meato" when challenged by the community's vegan diet it seemed to achieve only limited change in the participants with vague commitments to installing low energy lightbulbs and trying to use public transport more. The programme failed to challenge their belief that "oil isn't going to run out any time soon" or even provide any reasons to change other than the effects of diesel pollution in one Californian port town. So while recycling their "humanure" and running a car on discarded vegetable oil (which regular readers will know is NOT a scalable solution) may have been curiosities, there were few "take aways" for either the participants or the viewers. For me this was where "No Waste Like Home" succeeded by actually engaging the participants in their everyday environment and presenting them with both a "radical" and "practical" change to their energy usage from which both they and the viewers could learn from.


The Interflush

A different BBC television series "Dragons' Den" highlighted for me another issue. The series in which entrepreneurs pitch their ideas to "elite business experts" saw the inventor of the Interflush pitch his ideas to the panel of "business experts". The invention itself promises radical water savings "an unbeatable 47%" from a device which retails for around $30. Unfortunately a combination of a distinct vagueness on predicted sales figures and less than polished presentation skills meant there were no offers of investment. An affirmative answer by the inventor to the question "do you see yourself as more of an eco-warrior than an entrepreneur?" from the panel ended his chances. He was mocked for trying (and failing) to sell his invention to water companies who make money from selling more water. Yet isn't there something wrong when the world faces serious energy problems and oil, gas, electricity and water companies make bigger profits when people consume more. It is interesting therefore that energy giant BP in their latest marketing campaign asks "Do you know how big your carbon footprint is?". While the debate will continue as to just how green BP really is (the fact remains almost all their profits come from oil and gas) this campaign is getting people to think about their energy use which is definitely a good thing. Thinking about energy has to been a mainstream concern for all of us and our culture needs to change to reflect this. I'm interested in how readers think we should be creating this culture change.

Alternative Energy Zambia: Solar Power for Rural Electrification

One hundred and twenty one community-based organisations and nine schools in rural areas of Zambia will soon be getting BP Solar panels to generate electricity for lighting, radio, television and refrigeration. The panels will be supplied by BP Solar which has been awarded a contract by the Zambia Social Investment Fund. BP Solar is one of the world's largest solar companies and has manufacturing facilities in the United States of America, Spain, India and Australia.

Arnaud Mine, CEO of Apex-BP Solar, said: "This project is another example of the part solar energy is called on to play in sustainable development in Africa. It combines environmental, economic and social considerations, while obviating the need to set up capital-intensive infrastructure in the regions concerned. The same technology is already available in Europe for more specific applications."

The project will produce a peak power of approximately 250 kilowatts (kWp).

Alternative Energy Afghanistan: Solar Energy for Rural Use

The Asian Development Bank (ADB) has said that it has approved a $750,000-dollar grant to develop solar energy technology for use in isolated rural areas in Afghanistan.

The grant, financed by the British government, would demonstrate how solar energy could enhance the quality of life in poor, remote villages which could not be connected to wider power grids, the ADB said in a statement issued from its headquarters in Manila.

Most of Afghanistan’s population have no access to modern energy sources like electricity and gas and are forced to rely on traditional fuels like firewood. This depletes the country’s forests, damaging the environment.

However the country has a great potential for solar power since the sun shines for about 300 days a year in Afghanistan.

The grant will be used to provide solar energy systems to communities on a pilot basis and to train ten people from different ethnic groups as solar energy technicians at a training centre in India.

Upon returning to Afghanistan, they would train ten additional people from their communities.

It's hoped that solar energy systems in Afghanistan cam be used to provide lighting for literacy programs, provide water for clinics and to power water pumps and irrigation systems.

Alternative Energy Bangladesh: Reaching Where the Grid Can't

According to this editorial in the Financial Express of Bangladesh daily loadshedding and suspension of production in industrial zones due to low gas pressure clearly indicate that Bangladesh is experiencing a severe energy delivery crisis.

The editorial describes energy, and especially, electricity, as being one of the most important ingredients required to alleviate poverty and ensure socio-economic and human development.

Access to electricity in Bangladesh is one of the lowest in the world. The coverage at present stands around 30 per cent of the total population. However, the rural areas of Bangladesh, where nearly 80 per cent of the population live, are seriously deprived of electricity.

Larger energy supplies and greater efficiency of energy use are thus necessary to meet the basic needs of a growing population. As the conventional grid-fed electricity can only cover 15 per cent of the total households, tapping different sources of alternative energy can be used for the benefit of the people.

The government in its national energy policy clarified its vision that it wants to electrify the whole country by the year 2020. But, major electrification through grid expansion is not a viable option for most parts of Bangladesh in the foreseeable future mainly due to inaccessibility and low consumer density. There are many areas in the country where electricity will not reach in the next 30 years. Some experts say, the current rate of electrification will take decades to provide access to electricity to all people in the country. In contrast, favourable natural conditions like sufficient sunshine and wind-speed exist for promotion of alternative energy in Bangladesh.

To fulfil the Bangladeshi government's vision of universal electrification, alternative energy sources will have to take a vital role for off-grid electrification.

Of all the options, solar energy has so far been considered the most easy and viable option. Solar energy's attributes of needing no fuel, high durability and reliability and being able to operate for prolonged periods without maintenance make it economical for all types of remote applications.

Different private business houses have started introducing solar thermal and photovoltaic systems in rural areas.

As the Rural Electrification Board (REB) has a countrywide network through its cooperatives, it can take a leading role in electrifying rural Bangladesh instead of keeping it dependent on the Power Development Board (PDB), which provides it with gas-based electricity.

It has become increasingly clear that, for the development of alternative energy in Bangladesh, the funding windows of non-government and private sources as well as financial and development institutions should be augmented. Furthermore, innovative new financing opportunities including micro-financing may be utilised to attract private capital to supplement the energy deficiencies in rural areas and thus to fulfil the aspirations of the Bangladeshi poor.
