North Korea: Energy Security - Progress via Energy Aid?


almost empty streets at 5pm in Pyongyang in 2002

BBC News reported last month that South Korea has offered 2,000MW (2 Gigawatts) of free electricity to North Korea as an incentive to end its nuclear ambitions.

Seoul is proposing to lay power lines across the Korean border, as an alternative to a US-brokered nuclear power deal which collapsed in 2002.

Seoul is worried that if the North were to collapse, it could be flooded with millions of hungry North Korean refugees.

South Korea is one of the largest single donors of aid to the secretive communist state. It is the South's biggest donation to the North since 2000.

The UN World Food Programme is currently feeding some 6.5m North Koreans - nearly a third of the population.

The offer came as diplomats prepared to resume six-nation talks on the North's nuclear programme.

South Korean Unification Minister Chung Dong-young told a news conference that the power proposal would supply the same amount of electricity that the North would have received if two light-water reactors being built by an international consortium in the 1990s had been completed.

That deal, known as the Agreed Framework, collapsed after Pyongyang allegedly admitted to the US in 2002 that it had a secret, enriched uranium programme.

The proposed power lines would provide the North with 2m kilowatts of electricity a year from South Korea's own power grid, and would be ready by 2008.

The power being offered is equivalent to the output of two large power stations and would help towards redressing North Korea's serious energy shortage.

The BBC's Charles Scanlon in Seoul says the South Korean government has since seized the initiative, fearing that the confrontation between Pyongyang and Washington could escalate.

This may set an interesting precedent for other states with nuclear ambitions for power stations, if not nuclear weapons. Security of energy supply seems set to be an increasing area of conflict between nations although it doesn't have to be. There is an opportunity for the more technologically advanced nations to speed the transfer of the latest and cleanest power generation technology to developing nations and to cooperate in the development and utilisation of clean renewable energy.

Alternative Energy Vietnam: 400MW Geothermal Energy Capacity



Vietnams's Thanh Nien newspaper reports that the earth can be regarded as an enormous geothermal machine, the abundant energy of which is demonstrated by the eruption of the volcanoes, hot spring water, and hot natural air. Man is presently harnessing only a small fraction of that energy.

The start-up capital for such energy is around US$1.5 million per MW, which is 1.5 times more expensive than that of hydroelectricity, experts said.

Geothermal electricity, however, is more feasible than hydroelectricity with a shorter period of construction (estimated from 2 to 3 years), and a smaller construction site; a heat-storing tub located at several km underground, according to experts.

Developed countries like the US, Japan, Russia, and developing ones such as China, the Philippines, Malaysia, among others are making hectic preparations to construct geothermal power stations.

Vietnam finds itself located on the world geothermal map, with its capacity expected to be up to 400MW. The capacity of the US, for example, is 3170MW, Japan 458MW, Indonesia 379MW, and New Zealand 300MW.

Strikingly, the Philippines owns a resource capacity predicted to be as much as 2764MW, and it expects to catch up with the US in this field.

Vietnam’s potential regions are in the North West, North East, the North, and especially in South central Vietnam, in areas such as Le Thuy (Quang Binh), Mo Duc, Nghia Thang (Quang Ngai), Hoi Van (Binh Dinh), Tu Bong, and Danh Thanh (Khanh Hoa). Geothermal energy electricity projects seem to be very feasible, with completed plants forecast to have capacity ranging from 20MW to 50MW.

Geothermal energy’s output capacity is less than that of hydroelectricity, however, the preeminent and stability of the clean, environmentally-friendly, and permanent source of energy would play an important role in diversifying Vietnam’s energy sources.

In the 1990s, the US’s Ormat Corporation spent a lot of money and effort researching and planning to establish a geothermic electric plant in Vietnam with the capacity up to 20MW. It also agreed to sell the electricity to Vietnam Power Corporation at a competitive price, but Vietnam has no policy to favor such plan, and Ormat had to part with its project.

Among the hot sunny days with widespread lack of electricity in May, the Mechanics Institution, reporting to the Vietnam Science and Technology Institution, held a conference entitled "Developing and Using Geothermal Energy in Vietnam". The top outcome from the conference was that scientists expected the Vietnamese government to start developing Vietnam's geothermal energy sources soon.

Japan Seeks Protection From Crude Oil Prices By Reducing Energy Consumption




James Brooker reports in the New York Times that surging oil prices and growing concern about meeting targets on cutting emissions produced by burning fossil fuels have revived efforts around the world to improve energy efficiency. But perhaps nowhere is the interest greater than in Japan.

Even though Japan is already among the most frugal countries in the world, the government recently started a national campaign urging people to replace their older appliances and buy hybrid vehicles as part of a patriotic effort to save energy and fight global warming. And big companies are jumping on the bandwagon, counting on the moves to increase sales of their latest models.

On the Matsushita appliance showroom floor these days, the numbers scream not the low, low prices but the low, low kilowatt-hours.

A vacuum-insulated refrigerator, which comes with a buzzer that will sound if the door stays open more than 30 seconds, boasts that it will consume just 160 kilowatt-hours a year, one-eighth of the power needed by standard models a decade ago.

"It's like squeezing a dry towel" for the last few drops, said Katsumi Tomita, an environmental planner for Matsushita Electric Industrial. "The honest feeling of Japanese people is, 'How can we do more?"'

A number of other affluent countries with few domestic energy resources of their own are responding in similar ways. In Germany, where heating accounts for the largest share of home energy use, a new energy-saving law has as its standard the "seven-liter house."

The goal is to use seven liters, or 1.8 gallons, of oil to heat one square meter for a year, about one-third the amount consumed by a house built in 1973, before the first oil price shock. Three-liter houses - even one-liter designs - are now being built.

In Singapore, where year-round air conditioning often accounts for 60 percent of a building's power bill, new codes are encouraging the use of things like heat-blocking window films and hookups to neighborhood cooling systems where water is chilled overnight.

Other countries, including the United States, the largest energy consumer by far, have lagged behind, but even American consumers are starting to turn their backs on big sport utility vehicles and looking at more fuel-efficient cars in response to higher gasoline prices.

But Japan is where energy consciousness probably reaches the highest levels. The second-largest economy produces virtually no fossil fuels, importing 96 percent of its energy needs - a dependence that has led to tremendous achievements in improved efficiency. France and Germany, where governments crusade against global warming, expend almost 50 percent more energy to produce the equivalent of $1 in economic activity. Britain's energy use, by the same measure, is nearly double; that of the United States, nearly triple; and China's almost eight times as high.

From 1973 to today, Japan's industrial sector nearly tripled its output but kept energy consumption roughly flat. To produce the same industrial output as Japan, China consumes 11.5 times as much energy.

At JFE Holdings, a leading steel company, plastic pellets made from recycled bottles now account for 10 percent of fuel in the main blast furnaces, reducing reliance on imported coal. Japanese paper mills are investing heavily in boilers that can be fueled by waste paper, wood and plastic. Within two years, half of the electricity used in the country's paper mills is to come from burning waste.

As host nation for the Kyoto Protocol, the pact for cutting the so-called greenhouse gases suspected of being behind global warming, Japan takes its commitment seriously. But it faces a big challenge. According to figures released last month, Japan's emissions were 8.3 percent above the 1990 level for the year that ended on March 31, 2004.

Wind Energy Japan: Vestas Eyes Offshore Future

While it sees the Japanese mainland as a challenge due to the country's dense population, Danish wind turbine maker Vestas Wind Systems A/S is hoping to put some puff into its sales with offshore installations, the company's president said.

Svend Sigaard, president and chief executive officer of the world's largest wind turbine manufacturer, spoke to The Daily Yomiuri at 2005 World Exposition Aichi, where the company is exhibiting at the Nordic Pavilion.

"Japan is a densely populated country, and that makes the Japanese market more difficult compared with other markets. If we utilize the possibilities of nearshore installations or even offshore installations in the future, that will give us the possibility of continued use of wind energy.

If we go offshore, it's more expensive because the construction of foundations is expensive. But often the wind is stronger offshore, and that can offset the higher costs.

We're getting more and more competitive with our equipment. The price--if you measure it per kilowatt-hour produced--is going lower, due to the fact that turbines are getting more efficient. So we're creating increased interest in wind energy.

If you compare it to other renewable energy sources, wind is by far the most competitive today. If we're able to utilize sites close to the sea or at sea with good wind machines, then the price per kilowatt-hour is competitive against other sources of energy. "

Alternate Energy Japan: Energy Plan to Decrease Dependence on Oil

Japanese Prime Minister Junichiro Koizumi on Friday instructed ministers in his Cabinet to work out a long-term energy plan featuring increased use of alternatives to oil, such as solar and wind power, a government official said.

At a meeting of ministers on the country's energy policy, Koizumi said Japan should draft an energy plan that goes beyond the one the government has compiled up to fiscal 2010 and that the new plan should put priority on departing from oil dependency and boosting alternative energy consumption, the official said.

"We need to decrease consumption of oil and bring in new alternative energy sources including solar and wind power as well as fuel cells," Koizumi was quoted as saying. "That is the way we should transform our country from a nation with almost no resources."

Recent surges in crude oil prices to record-high levels are behind the policy, the official said.

The premier said nuclear power is an important source of energy for Japan but it would be difficult to increase the number of nuclear power plants.

Some electric power companies have become reluctant to promote nuclear plant construction because of local opposition and the high cost of building and running the plants, analysts say.

Under the government's revised energy supply plan, which is expected to be formalized by May, Japan aims to lower dependence on petroleum in primary energy supply from 47 percent in fiscal 2000 to 41 percent in fiscal 2010.

Considering the technological lead Japanese automakers like Toyota and Honda have shown in hybrid technology, it is time for the Japanese government to show leadership in promoting plug-in hybrid technology and alternative energy. By doing so Japan can lock in long term electricity and transportation fuel prices and reduce its significant exposure to rises in fossil fuels prices. It also has an opportunity to set an example on an international level by leading the way to a post oil age.

Alternate Energy China: Renewable Energy Law sets 10% Target

BBC News reports that China's government has passed a renewable energy law which is intended to increase production of energy from sustainable sources.

The law, which will come into force early next year, seeks to increase the usage of solar and wind power to 10% of China's total consumption by 2010. This would equate to around 60 gigawatts.

However, while the new law has been welcomed, it has been suggested that the targets are over ambitious.

Rising oil prices and concerns over environmental damage prompted the move.

At present China relies on coal for most of its power, mining 1.8bn tons in 2004.

By fixing prices for electricity from solar and wind generated power, the government hopes to create financial incentives for existing operators and attract investment to these new markets.

But while there has been rapid expansion in the sustainable energy sector, it currently provides only a fraction of China's needs.

Currently wind power in China only contributes 0.01% to the power grid. To increase that to 10% in five years is ambitious, but in my opinion it's a target well worth aiming for. If China takes the same relentless attitude to pushing down the costs of wind turbine manufacture as it does with consumer goods the benefits may be realised around the world.

Alternate Energy Pakistan: US $875m Windpower Project to Provide 30% of Karachi's Needs

A new US$875 million wind power project will provide 30 percent of Karachi's power needs, a state government official has said. Speaking at the inauguration of the Gharo project, adviser to Sindh Chief Minister for Environment and Alternate Energy, Noman Saigol, said it was the first alternate energy project for Sindh.

Sixteen companies from the US, Japan and China are taking part in the project, which will be built on 19,700 acres of government-provided land.

The windpower project, expected to employ 30-40,000 locals, will have a 50MW capacity, rising to as much as 900MW by 2010, he said.

Site Agreed for Australian Solar Tower, Plans for Solar Tower in China



The firm behind the plan to build a power-generating solar tower (also described as a solar chimney) - touted as the world's tallest structure - in Outback New South Wales is to sign an agreement to buy the site.

Melbourne-based Enviromission will buy a 10,000ha slice of Tapio station at Buronga, 25km northeast of Mildura, to build the 1km tower.



Enviromission chairman Roger Davey confirm the purchase price was in excess of a million dollars (USD). The agreement will be signed in Mildura, about 350 miles northwest of Melbourne, before an audience of community leaders.

"It confirms our commitment to the site and the Sunraysia region for the first solar tower."

The mammoth project, worth hundreds of millions of dollars, will be built by the end of 2009.

The reinforced concrete tower will cover approximately one square kilometres at its base and will be surrounded by a "greenhouse" of glass, polycarbonate and polymer. Air at 30C at the edge of the glasshouse is heated up to 70C at the centre, where the tower draws it through 32 turbines to the cooler air above.

The power station will produce up to 200 megawatts of electricity and can generate 24 hours a day.

EnviroMission and SBP estimate the cost of their first 200-megawatt solar thermal tower at $670m, and say the cost of subsequent towers would fall. An engineering infrastructure, materials manufacturing plants and trained workforce would be in place and the design and construction would have been refined.

The initial cost is comparable with the $600m cost of building a new 200MW brown-coal power station and a drying plant for the coal, which is nearly 70% water by weight. A 200MW black-coal power station in Queensland would cost $440m. These prices ignore the unknown environmental and health costs of greenhouse gas, sulphur and particulate emissions from coal-fired power stations.

Each solar tower would abate between 920,000 tonnes of carbon dioxide emissions annually from fossil fuels. Solar towers would help lessen Victoria's heavy dependence on brown coal-sourced electricity.

Enviromission floated on the Australian Stock Exchange in 2001. Its major investor is the owner of the solar tower technology, US company SolarMission Technologies.

Enviromission has the exclusive Australian rights to the technology, first developed on a much smaller scale in Spain in the early 1980s, using a German design.

There are also plans to invest a further US$8 million for development of a solar tower in China.

Enviromission will be a part owner of a global intellectual property company that will benefit from solar towers built around the world, Davey said.

The pre-feasibility study was completed successfully in February last year.

Alternate Energy Philippines: MicroHydro Power

The Philippine Daily Inquirier has a number of special reports on the country's "preventable crisis" of energy supply including this one on the use of micro-hydro electricity.

While there is talk of a coming energy crisis in some areas of the Philippines, including Mindanao and the Visayas, in the remote communities in the Cordilleras, microhydroelectricity is being put to use.

Microhydro power plants (those with 7.5 to 35 kW capacity) don't need big, controversial dams to operate.

In fact, a small spring in Barangay Buneg, Conner town, Apayao province and in Barangay Lon-oy, San Gabriel town, La Union province - has enough power to run a generator for household electricity.

Hardly accessible, Buneg and Lon-oy are among 10,000 villages not covered by the National Power Corp. (Napocor) grid. Under the Philippine Energy Plan, Buneg and Lon-oy are among the villages due to be electrified 2010. But this is only on paper.

Remote communities and non-government and Church organizations advocating micro-hydro power say they cannot wait for the government to bring electricity to them.

So, on their own, representatives of the 300 Mabaka people of Buneg got in touch with the Catholic Church and the Sibol ng Agham at Teknolohiya, or Sibat, a Metro Manila-based non-government organization helping install environment-friendly and community-run alternative energy facilities.

From 1996 to 2002, the Mabaka folk had provided labor and Sibat, through its engineer, the project supervision. Sibat also sourced funds from the United Nations Development Programme.

Inaugurated in January 2003, the Buneg 7.5-kW micro-hydro power plant has since been providing electricity to 36 families.

Under bright fluorescent lamps, children can now study their lessons and read books while Rosalina Dangli, the community's lone public teacher, can prepare her lesson plans.

Before he calls it a day, Mabaka elder Andanan Agagen weaves rattan baskets at night, which he sells to lowland folk in Conner town.

Courtesy of the Episcopal Church of the Philippines and the community, a 15-kW micro-hydro power facility in Lon-oy has not only lit up the 130 houses of 1,000 upland farming folk. The facility has also enabled many families to make brooms for sale, even at night.

And now that the electricity is flowing, the women have embarked on money-earning ventures such as processing ginger into salabat or ginger tea powder.

Other privately initiated micro-hydro power plants are starting a quiet industrial revolution in areas inaccessible to national power company.

A 5-kW micro-hydro power project built in 1993 in the sub-village of Ngibat in Tinglayan town, Kalinga province, powers a blacksmith shop, which manufactures simple farm tools such as trowels, hoes, bolos and machetes for the 30 families in the community. It also operates a community rice mill and a vulcanizing shop.

A 30-kW micro-hydro power facility in Tulgao village, also in Tinglayan, built in 1999 also with the help of Sibat, now runs a rice mill and a sugarcane presser, which is twice faster than the carabao-drawn dapilan (wooden presser).

The Cordillera's various springs and tributaries offer great potential for small water-powered electricity generators.

Alternative Energy China: Asia's Largest Wind Farm



A private company plans to build Asia's biggest wind farm in the sea south of Shanghai, setting up 100 turbines in shallow coastal waters, an industry group said Thursday.

The announcement of the 2 billion yuan (US$250 million) project comes as China struggles with severe electricity shortages while also trying to reduce its heavy reliance on dirty coal-fired power plants.

Zhejiang Green Power Investment Co. is to build the project along the coast of Daishan County in Zhejiang, the province south of Shanghai, the China Electricity Council said. It didn't say when construction was to begin.

The wind farm is to have a generating capacity of 200 megawatts, according to the council, the main trade group for China's power industry.

At the end of 2004, China's total wind power capacity was a mere 730 megawatts.

Alternative Energy Vietnam: Pico Hydro - Small Scale Hydro-Electric Energy



Hanoi, the booming capital of Vietnam, according to the BBC epitomises the country's Asian tiger status. But while the standard of living in the cities has risen dramatically over the last few decades, in the countryside it is a different story.

The mountainous Da Bac province, outside Hanoi, is home to the Muong indigenous ethnic group. Many are rice farmers and few can afford the electricity from the new pylons that line the valleys. Instead, they are turning to a low-priced alternative.

Pico Hydro is a small-scale version of conventional hydro-electric power generation. The streams at the bottom of the valleys are powering a low-tech grid for the people of Da Bac.

Pico Hydro units need only a constant water supply and a slope with a one-metre drop. This produces a flow rate that can drive a turbine fast enough to generate electricity, providing houses with a direct power supply.

In some villages nearly every household has one. Imported 300-watt turbines cost about US$20, and have proved to be the most popular.

"Using Pico Hydro is really easy. There aren't any difficulties. It's actually more difficult to use the high voltage grid - it's much more expensive for us," says Ban Van Giang who lives in Da Bac.

"With better lighting, my wife can work and walk in the house easier, and my children can have better light to do their homework."

Vietnam has the world's highest uptake of Pico Hydro, with 120,000 units installed so far.

Cheap renewable means of generating electricity like Pico Hydro are key to spreading the benefits of electricity throughout the world in a sustainable way.

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.
