Beijing Conference Shows Renewable Energy Booming Worldwide

 

BEIJING, China, November 7, 2005 (ENS) - The fastest growing energy technology in the world is grid-connected solar photovoltaic, which grew in capacity by 60 percent per year from 2000 through 2004, to cover more than 400,000 roofs in Japan, Germany, and the United States, according to a Worldwatch Institute report released today at the Beijing International Renewable Energy Conference.

 

Second is wind power capacity, which grew by 28 percent last year, led by Germany, with almost 17 gigawatts installed as of 2004, the report finds.

 

"Renewable energy has become big business," said Eric Martinot, lead author of "Renewables 2005: Global Status Report." The report was compiled by Martinot, working with more than 100 researchers and contributors from at least 20 countries as a project of the Renewable Energy Policy Network for the 21st Century (REN21).

 

The report was produced and published by the Worldwatch Institute and released at the Beijing International Renewable Energy Conference 2005, sponsored by the government of .

 

At the conference today, Chinese President Hu Jintao called on the international community to improve cooperation in research and development, technological transfer and funding for the use of renewable resources to benefit the world.

 

The state news agency Xinhua quoted Hu as telling conference delegates that giving priority to the exploitation and use of renewable energy is the only way for the world to deal with the growing energy and environmental problems, and the only way for humankind to achieve sustainable development.

 

Chinese Vice-Premier Zeng Peiyan told the conference that China will develop its water resources, build wind power plants capable of generating a million kilowatts each, pay more attention to the use of solar energy, and methane in rural areas, and promote the biological energy sector. By 2010, renewable energy will account for 15 percent of China's energy supplies, said the vice-premier.

 

Xinhua quoted Vice minister of the National Development and Reform Commission Zhang Guobao as saying the Chinese government will raise about US$180 billion to develop renewable energy from now to 2020.

 

The conference gathers government and private leaders from around the world, providing a forum for international leadership on renewable energy. It reconnects the stakeholders that came together at the International Conference for Renewable Energies in Bonn, Germany in 2004.

 

Martinot, who is a senior fellow at the Worldwatch Institute and a lecturer at Tsinghua University in Beijing , notes that renewable energy is attracting some of the world's largest companies, including General Electric, Siemens, and Sharp.

 

Global investment in renewable energy set a new record of $30 billion in 2004, Martinot and his team report.

 

By design, the report does not provide analysis, recommendations, or conclusions. It provides an assessment of small hydro, modern biomass, wind, solar, geothermal, and biofuels, energy sources that are now competing with fossil fuels and nuclear power in four distinct markets - power generation, hot water and space heating, transportation fuels, and rural off-grid energy supplies.

 

Technologies such as wind, solar, biomass, geothermal, and small hydro now provide 160 gigawatts of electricity generating capacity, about four percent of the world total. Developing countries have 44 percent of this capacity.

 

This 160 gigawatt slice of generating capacity compares to 3,800 gigawatts installed capacity worldwide for all power generation.

 

The report finds that government leadership provides the key to market success and that government support for renewable energy is growing rapidly.

 

At least 48 countries now have some type of renewable energy promotion policy, including 14 developing countries. Most targets are for shares of electricity production, typically five to 30 percent, by the 2010 - 2012 timeframe.

 

Legislation requiring the blending of biofuels into vehicle fuels have been enacted in at least 20 states and provinces worldwide as well as in three populous developing countries - Brazil, China and India.

 

The market leaders in renewable energy in 2004 were Brazil in biofuels, China in solar hot water, Germany in solar electricity, and Spain in wind power.

 

In total, renewable energy industries worldwide provide 1.7 million jobs, most of them skilled and well-paying.

 

Over 4.5 million green power consumers in Europe, the  United States, Canada, Australia, and Japan purchased renewable electricity at the retail level or via certificates in 2004.

 

The report estimates that nearly 40 million households worldwide heat their water with solar collectors, most of them installed in the last five years.

 

Sixteen million households cook and light their homes with biogas, and two million households use solar lighting systems.

 

Production of the biofuels ethanol and biodiesel exceeded 33 billion liters in 2004, when ethanol displaced about three percent of the 1.2 trillion liters of gasoline produced globally.

 

Interest in using renewable energy technologies to provide electricity to rural and remote areas as a cost-effective alternative to grid extension is gathering momentum in many developing countries, the report finds. An estimated 360 million households worldwide still lack access to to central electric power networks.

 

“All our client countries in Latin America have told us that they have realized that they need subsidies and regulatory measures for reaching the ‘last 20 percent’ of their rural unelectrified populations, including with renewable energy,” said a World Bank project manager quoted in the report.

 

Brazil plans to electrify 2.5 million households by 2008 under the “Luz para Todos” program, and about 700,000 households have already been electrified. Brazil has targeted 200,000, or about 10 percent of these households for renewable energy.

 

Several other Latin American countries have recently launched or revamped new rural electrification programs, including Bolivia, Chile, Guatemala, Mexico, Nicaragua, and Peru. Most of these countries have launched efforts to “mainstream” renewable energy as a standard option of new rural electrification efforts. The report finds that Chile has recently recognized renewables as a key technology as it enters a second phase of a national rural electrification program.

 

Asian countries with mandates for renewable energy for rural electrification include Bangladesh, China, India, Nepal, the philippines, Sri Lanka, countries are financing programs with multilateral assistance, and conducting other technical assistance and support measures.

 

The report estimates that US$500 million goes to developing countries each year as assistance for renewable energy projects, training, and market support. The German Development Finance Group, the World Bank Group, and the Global Environment Facility provide the majority of these funds, and dozens of other donors and programs provide the rest.

 

REN21 is a global policy network aimed at providing a forum for international leadership on renewable energy. Its goal is to allow the rapid expansion of renewable energies in developing and industrial countries by bolstering policy development and decision making on sub-national, national, and international levels.

 

The establishment of a global policy network was embraced in the Political Declaration of the International Conference for Renewable Energies, Bonn 2004, called Renewables 2004, and formally launched in Copenhagen in June 2005.

 

The REN21 Steering Committee brings together government officials from Brazil, China, Denmark, the European Commission, Germany, India, Morocco, Netherlands, Uganda, the United Kingdom and the United States with nongovernmental leaders such as Greenpeace, the Worldwatch Institute, WWF, and the African Energy Policy Research Network.

 

Multilateral agencies are represented on the Steering Committee by the United Nations Environment Programme and the International Energy Agency among others. Funding agencies are represented by the World Bank and the Global Environment Facility. Industry associations include the World Wind Energy Association, and the Renewable Energy Councils from Europe and the United States.

 

WorldWatch says the Global Status Report fills a gap in the international energy reporting arena, which has tended to neglect the emerging renewable energy technologies. Regular updates will be produced in the future.

How to Live Without Oil

 

New energy sources and efficiency could make petroleum obsolete.

By Amory B. Lovins

Newsweek International

Aug. 8, 2005 issue - In 1850, most homes in the were lit by lamps that burned whale oil. As demand rose, supply dwindled—whales became shy and scarce—and prices for whale oil climbed. Then alternative fuels such as smokeless, odorless coal-kerosene began to sweep the market. By 1859, when Edwin Drake struck oil in Pennsylvania , five sixths of all whale-oil lamps had switched to the new fuels. The astonished whalers, who hadn't heeded the competition, ran out of customers before they ran out of whales.

Oil may now be poised to repeat that history. With prices exceeding $50 a barrel, the world's oil habit now costs $4 billion a day. Some experts warn that output will soon peak and prices will reach $100, but nobody really knows for sure (94 percent of reserves are owned by governments, which generally keep the data secret). Fortunately, it doesn't matter: With cheap oil-saving technologies and alternative fuels already at our disposal, the sooner we get off oil, the sooner we'll start making bigger profits.

That's right—profits. The conventional wisdom is that $50-a-barrel oil has made alternatives to fossil fuels economically viable. But the truth is that they were viable back when oil was $25 a barrel. The arguments in favor of phasing out oil have now merely become overwhelming.

That's true everywhere—but nowhere more so than in , the world's biggest oil consumer. It's entirely possible to cut projected oil consumption in half by 2025, and eliminate it completely by 2050, without compromising rapid economic growth. Demand could be halved simply by using oil twice as efficiently over several decades; the other half could be replaced with saved natural gas and advanced biofuels. According to a policy analysis we published last year at Rocky Mountain Institute ("Winning the Oil Endgame"), the cost of these changes would average $15 a barrel. Even if, as the U.S. government forecasts, oil comes down in price by 2025 to $26 a barrel, the net saving in the United States would still be $70 billion a year, and the rest of the world would benefit proportionally. Burgeoning economies like China and India have the most to lose from falling into a U.S.-style oil trap, and the biggest opportunity to avoid it by making their vehicles, buildings and factories efficient from scratch.

Doubling oil efficiency wouldn't be hard. A backlog of powerful ways to save and substitute for oil, amassed since the 1973 oil embargo, remains mostly untapped, even in the most energy-efficient countries. Automakers for instance could profitably increase fuel mileage to 66 mpg (3.6L/100km) for light trucks and 92 mpg (2.6L/100km) for cars. Doing so would cost an extra $2,550 for a midsize SUV, but would pay for itself in fuel savings in two years in the and in one year in Europe .

This would require combining hybrid-electric propulsion with new lightweight steels or, in a few years, carbon composite parts that absorb six to 12 times more crash energy per kilogram. New manufacturing processes could then make cars big, protective and comfortable with halved weight and fuel use at no extra cost. The military could pioneer such ultralight, ultrastrong vehicles to modernize its forces.

Modern aerodynamics, tires, engines and materials can cheaply double or triple the efficiency of 18-wheel heavy trucks and jetliners, too. Boeing's new 787 consumes 20 percent less fuel per passenger mile than its predecessor. Retooling the car, truck and plane industries would require a $90 billion investment. That may sound like a lot, but spread over a decade, it's worth about three weeks of oil imports a year. Other countries' retooling would typically yield at least as handsome profits in both money and security.

Once the has saved half its oil, it can cost-effectively replace an additional 20 percent with advanced biofuels, and the rest with saved natural gas. Biofuels (based on woody, weedy plants—not corn) will need a $90 billion investment, too, but they'll beat $26 oil, revitalize farming, protect topsoil better and preserve food crops' land and water. Harvesting biofuel crops, carbon credits and wind power all from the same land, much of it now unproductive, can also double or triple net farm and ranch income. Again, details will differ in other countries, but the opportunities are broadly similar—even in , which lacks the Great Plains but is 70 percent forested and could substainably harvest both fiber and biofuels there.

Eliminating oil demand in the would thus require a $180 billion investment, half for efficient vehicles, half for advanced biofuels. By 2025, that would save $155 billion every year, create a million new jobs, save a million current jobs and generate 26 percent less carbon emissions. Benefits in Europe, Asia and Latin America are proportional or better. Even oil-exporting countries could benefit: oil may well ultimately be worth more for its hydrogen content than for its hydrocarbons.

Mandates, subsidies and taxes aren't needed to implement these changes. What's needed are smart business strategies and enlightened government policies that remove barriers to adopting new technology. The most important would be to offer "feebates"— a charge on inefficient vehicles that would be rebated to buyers of efficient ones, within each size class. Government would also play a role in helping retool car plants, retrain workers, scrap gas-guzzler planes and cars, and so forth. Customers would have more choices, workers more jobs, everyone more profits. In only two generations, oil—once the foundation of our strength but now a source of weakness—could become as obsolete as whale-oil lamps.

We are not at the end of the oil age: New developments soon will increase the world’s supply

 

WE are not running out of oil - not yet. "Shortage" is certainly in the air - and in the price.

 

 

Right now, the oil market is tight, even tighter than it was on the eve of the 1973 oil crisis. In this high-risk market, "surprises" ranging from political instability to hurricanes could send oil prices spiking higher.

 

 

Moreover, the specter of an energy shortage is not limited to oil. Natural gas supplies are not keeping pace with growing demand.

 

 

Even supplies of coal, which generates about half of the country's electricity, are constrained at a time when our electric power system has been tested by an extraordinary heat wave.

 

 

But it is oil that gets most of the attention. Prices around $60 a barrel, driven by high demand growth, are fueling the fear of imminent shortage - that the world is going to begin running out of oil in five or 10 years.

 

 

This shortage, it is argued, will be amplified by the substantial and growing demand from two giants: and .

 

 

Yet this fear is not borne out by the fundamentals of supply. Our new, field-by-field analysis of production capacity, led by my colleagues Peter Jackson and Robert Esser, is quite at odds with the current view and leads to a strikingly different conclusion:

 

 

There will be a large, unprecedented buildup of oil supply in the next few years. Between 2004 and 2010, capacity to produce oil (not actual production) could grow by 16 million barrels a day - from 85 million barrels per day to 101 million barrels a day - a 20 percent increase.

 

 

Such growth over the next few years would relieve the current pressure on supply and demand.

 

Where will this growth come from? It is pretty evenly divided between non-OPEC and OPEC.

 

 

The largest non-OPEC growth is projected for , , , , and . In the OPEC countries, significant growth is expected to occur in , , and , among others.

 

 

Our estimate for growth in is quite modest - only 1 million barrels a day - reflecting the high degree of uncertainty there.

 

 

In the forecast, the remains almost level, with development in the deep-water areas of the Gulf of Mexico compensating for declines elsewhere.

 

 

While questions can be raised about specific countries, this forecast is not speculative. It is based on what is already unfolding.

 

 

The oil industry is governed by a "law of long lead times." Much of the new capacity that will become available between now and 2010 is under development. Many of the projects that embody this new capacity were approved in the 2001-03 period, based on price expectations much lower than current prices.

 

 

There are risks to any forecast. In this case, the risks are not the "below ground" ones of geology or lack of resources. Rather, they are "above ground" - political instability, outright conflict, terrorism or slowdowns in decision-making on the part of governments in oil-producing countries. Yet, even with the scaling back of the forecast, it would still constitute a big increase in output.

 

 

This is not the first time that the world has "run out of oil." It's more like the fifth. Cycles of shortage and surplus characterize the entire history of the oil industry.

 

 

A similar fear of shortage after World War I was one of the main drivers for cobbling together the three easternmost provinces of the defunct Ottoman Turkish Empire to create . In more recent times, the "permanent oil shortage" of the 1970s gave way to the glut and price collapse of the 1980s.

 

 

But this time, it is said, is "different." A common pattern in the shortage periods is to underestimate the impact of technology. And, once again, technology is key. "Proven reserves" are not necessarily a good guide to the future.

 

 

The current Securities and Exchange Commission disclosure rules, which define "reserves" for investors, are based on 30-year-old technology and offer an incomplete picture of future potential. As skills improve, output from many producing regions will be much greater than anticipated. The share of "unconventional oil" - Canadian oil sands, ultra-deep-water developments, "natural gas liquids" - will rise from 10 percent of total capacity in 1990 to 30 percent by 2010.

 

 

The "unconventional" will cease being frontier and will instead become "conventional." Over the next few years, new facilities will be transforming what are inaccessible natural gas reserves in different parts of the world into a quality, diesel-like fuel.

 

The growing supply of energy should not lead us to underestimate the longer-term challenge of providing energy for a growing world economy.

At this point, even with greater efficiency, it looks as though the world could be using 50 percent more oil 25 years from now. That is a very big challenge.

 

But at least for the next several years, the growing production capacity will take the air out of the fear of imminent shortage.

 

 

And that in turn will provide us the breathing space to address the investment needs and the full panoply of technologies and approaches - from development to conservation - that will be required to fuel a growing world economy, ensure energy security and meet the needs of what is becoming the global middle class.

Wind farms: For and against

 

 

A new wind farm is planned in . Local girls Angelica and Sarah have very different views on it.

 

Angelica tells us why she thinks it's a good idea, and Sarah lets us know why she's very much against it.

 

 

For

 

"It's important to have clean power sources like wind farms to stop pollution.

 

This wind farm will be safer than something like a nuclear power station, and doesn't put out lots of harmful gasses.

 

They're not that nice to look at, but it's much better to have them than to ruin the whole environment with holes in the ozone layer and global warming.

 

They don't cause much damage, and they're not very noisy, so we should use them as much as possible.

 

Having a mixture of different power sources is the best way forward, and will help us all in the future."

 

Angelica, 10,

 

 

Against

 

"People think wind farms are clean and safe, but they're not.

 

Lots of rare birds get hurt or killed in the blades of the wind mills.

 

They're trying to stop pollution, but they don't think of the consequences.

 

Digging up the peat to make this farm will release loads of carbon dioxide into the atmosphere, which will add to the greenhouse effect.

 

I'm not totally against the farms, but they don't belong in the countryside, where they cause lots of damage.

 

The best form of power is hydro-power. It runs on waves and the tide - which are always there.

 

Once these farms are made, there's no going back - they'll always be there!"

 

Sarah, 11, Cumbria
