Alternative Energy Inspires Young Scientists



In Indianapolis a number of the 1,500 young scientists competing in the International Science and Engineering Fair for $4 million dollars in prizes and scholarships pursued alternative energy innovations.

Seventeen year old Allison Wilson from Stuart, Iowa, won $11,000 in scholarships by making ethanol fuel from prairie grass.

Renewable energy also inspired 17 year old Brian Sutterer of Terre Haute, Indiana, who generated electricity using the difference in temperature above and below ground (geothermal energy).

Ethanol Fuel in South Africa


photo (c) 2005 Julia Freeman

Tumi Makgetla reports in South Africa's Mail & Guardian that while an interest in alternative energy and green politics is often seen as the preserve of the chattering classes, working-class people in Johannesburg's inner city are already using renewable energy in their homes.

On a pavement in Joubert Park in Joburg (how Johannesburg is commonly called), shoppers cluster around Tumelo Ramolefi’s stall exclaiming and asking questions about his products. Ramolefi is not selling the usual inner-city hawker stock of facecloths and socks, or "smileys" (boiled sheep heads) and "runaways" (pigs’ trotters). Instead, it is his display of innovative renewable-energy gadgets that attracts the attention of passers-by, and often turns them into converts to the green-energy cause.

His bestselling items are ethanol gel stoves and lamps, which offer a healthier, safer and more efficient fuel alternative to paraffin or coal fires.

Ethanol gel is a renewable form of energy made by mixing ethanol with a thickening agent and water. The ethanol is extracted through the fermentation and distillation of sugars from sources such as molasses, sugar cane and sweet sorghum or starch crops, like cassava or maize.

Ramolefi sells ethanol gel products and appliances for GreenHeat South Africa, which has branches in Durban, Jo’burg and Cape Town. The stoves and ethanol gel -- produced from sugar cane -- are manufactured in Durban. A two-plate stove sells for R160 (approx. $25 USD) and a lamp for R50 (around $8).

"This stove is number one," said Maria Ndlela, who works in a recycling centre in Joubert Park and has owned her stove for two months. She says it is easy to use and, while paraffin is cheaper than the gel, the gel is more cost-efficient in the long run. Five litres of gel costs about $9.70 and paraffin costs approximately $3.55 for the same amount. "Gel lasts. If you don’t use it too much, five litres of gel takes you a month to use, but five litres of paraffin lasts only three days."

Ndlela says an added attraction of ethanol is that the paraffin price fluctuates. “The price of paraffin is going up and down, up and down with the petrol price,” she said, “So now I’m forgetting about paraffin.”

“What I like about the stove is that it will conquer our unreliable electricity,” said Florah Thulare.

Safety is also a big selling point in favour of ethanol products, particularly for those who use coal or paraffin for heat and cooking. Paraffin stoves, which explode or are easily knocked over, cause fires, and poor ventilation can lead to asphyxiation.

"Coal can actually kill you during the night," says Ramolefi. "In this coming month, we know people are going to die, but there’s no campaign."

Gel fuel burns with a carbon-free flame, so it does not cause respiratory problems such as asthma, which can be caused by emissions from paraffin, coal and wood fuel. The gel also does not produce any smoke or smell.

Gel fuel will not ignite if spilt like gas or paraffin. The gel is non-toxic and thus is not poisonous if swallowed by children. The stoves are designed so they will not fall over if bumped and the stove’s legs allow it to slide when pushed instead of toppling over. Even if an ethanol lamp is overturned, the gel will extinguish the wick.

The stoves are designed for cooking, but about half of his customers buy them as heaters, said Ramolefi.

Ramolefi has sold about 70 stoves in the past eight months and hopes the market will grow and prices will consequently drop, making the stoves more affordable for the poor.

Austin Energy Excels as #1 Green Energy Electricity Utility in America



UPDATE: This is a list of the top ten green energy programs in the United States with the latest December 2005 figures and links to these electric utilities. One of the biggest differences we can make is to switch to "green energy" - energy generated from 100% renewable sources. Florida Power & Light is a new entry into the top ten at number four. The company recently announced the construction of the largest solar array in Florida on the site of a closed landfill in Sarasota. The 1,200 photovoltaic solar panels are each about 31 inches wide and 63 inches long. The facility is to be more than 28,000 square feet, or about half the size of a football field. "We sought a location that had a ground site large enough for 250 kilowatts of photovoltaic panels," said Jeff Bartel, FP&L VP of external affairs.

If you live in a part of the United States that is not served by an electric utility on this list please see this Map of Green Energy Providers by State.

As our energy challenges are global I appreciate every assistance in compiling a similar list of renewable energy providers in other countries. Feel free to email or leave a comment.

Returning to the United States, Austin Energy has shown its commitment to renewable energy by topping the list. The U.S. Department of Energy said Austin Energy's Green Choice program sold more than 334 million hours of renewable energy last year.

More than 350 businesses in Austin get their power from renewable sources as an alternative to fossil fuels.

Austin Energy uses electricity from 61 West Texas wind turbines.

Here's the top ten green energy programs in the United States (as of December 2005).

List of Green Energy Providers by State

One of the single biggest ways we as individuals can encourage the use of alternative energy and help aid the transition to a post fossil fuel age is to buy electricity partly, or preferably completely, generated using alternative energy.

Switching your electricity utility provider may be as simple as requesting a form or filling one in online. That's exactly how I switched to 100% renewable energy (generated mainly from wind power with some solar power and small scale hydro thrown into the mix). Renewable energy options are available throughout the U.K. and in many other countries.

To find out if you can switch to renewable energy in your area look on your search engine of choice for "green energy", "green power" or "green electricity". You may also need to add your location to the search. If your local utility doesn't provide a renewable energy option yet, email or call them and ask why.

Mixed Signals & Federal Funding for Alternative Energy Research



There have definitely been some mixed signals on alternative energy research recently. At the same time President Bush's State of the Union address called for a 22 percent increase in federal spending to develop alternative energies, dozens of staffers and contractors for the National Renewable Energy Laboratory in Golden, Colorado, were being laid off.

The disconnect was a political embarrassment for the president, so federal officials restored the laboratory's funding, rehiring the workers who had been laid off just in time for President Bush’s scheduled speech at the NREL.

In his speech the President acknowledged the confusion, “I recognize that there has been some interesting mixed signals when it comes to funding," President Bush said.

This comes at a time when a new national public opinion survey demonstrates overwhelming public support in the United States for government policies and investments that will support development of alternative energy sources. The survey of 1,000 registered voters was conducted by Public Opinion Strategies of Alexandria, VA, for the Energy Future Coalition. The survey’s findings included:

According to the survery there is nearly unanimous support for a national goal of having 25% of the United States domestic energy needs met by alternative energy by the year 2025. Ninety-eight percent of voters see this goal as important for the country, and three out of four (74%) feel that it is "very important." Ninety percent of voters believe this goal is achievable.

Similar majorities support government action to encourage greater use of renewable energy. Eighty-eight percent of voters favor financial incentives, and 92% support minimum government standards for the use of renewable energy by the private sector.

Nearly all voters (98%) say the costs, such as the cost of research and development and the cost of building new renewable energy production facilities, would be worth it to get the United States to the 25% by 2025 goal.

Voters consider energy to be an important issue facing the country, rating it similarly with health care, terrorism and national security, and education, and ahead of taxes and the war in Iraq. Half (50%) of voters believe America is headed for an energy crisis in the future, and 35% believe the country already is facing a crisis.

So just how much is the United States government spending on alternative energy research? After the 22% increase the budget will stand at $771 million. This amounts to less than one percent of the $55,000 million the federal government spends annually on research, nearly half of which is devoted to healthcare.

It’s time for action.

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.

Alternative Energy Ecuador: 15MW Windfarm for Loja


Vilcabamba, Loja Province, Ecuador

Ecuadorian company Villonaco Wind Power, 80%-owned by Canadian alternative energy generator Protocol Energy, is scheduled to begin construction of a 15MW wind park this month in Ecuador's Loja province, Protocol chairman and CEO Thomas Logan told BNamericas.

Villonaco is 20%-controlled by Loja province-owned generator Enerloja.

Operations are scheduled to commence November-December 2006 on schedule.

So far all funding for the US$26mn project has been provided by Logan and a private placement of up to 1.6 million shares at CDN$0.50/share, which is 50% completed.

Several companies submitted bids to manufacture the wind turbines last May. Villonaco has narrowed the field down to two companies, Spanish wind power firm Gamesa Eólica and German wind power equipment manufacturer Nordex, and should announce its decision this month, Logan said.

The turbine tender does not only pertain to this venture but also to two additional investment phases in the country, the second of which is a 30-65MW wind farm in the feasibility stage, with construction scheduled for the first half of 2007. The third investment phase is a 25-40MW expansion of the Villanoco wind farm.

The second level of Protocol's strategy is to launch a wind project in Peru and/or Chile, with internal studies indicating that execution of a 125-150MW program would be appropriate in Chile for 2007.

"Along the Andes in Ecuador, Peru, and Region I and II in Chile you're dealing with a wind regime that blows, in the case of Ecuador, with a median speed of 12.5m/s, so about 80% better than the best wind in Canada. But more importantly, it blows at that level for 13 hours/day," Logan said, adding that the turbines will continue turning 24 hours a day.

The company aims to sell power to mining companies "simply because miners are energy hogs. The average mine has operating costs that are 20% energy-related. They all have the same requirements, which is a stable and guaranteed source of energy at a reasonable price, and wind does that," Logan said.

Within four years Protocol aims to generate 400-500MW of wind, geothermal, biomass and run-of-the-river hydro power through its global endeavors, which have an initial focus in Latin America.
