Even as Britain, following a detailed review, mulls the need for increased nuclear capacity, Spain has the bit between its teeth as it champions renewable energy.
Spain is in the EU renewables vanguard as the EU targets a 20 percent share of overall energy production by 2010, compared with a projected 3 percent for Japan.
Wind farms are a major part of the national strategy and the share of overall wind farm-generated production is set to double to 12 percent over the next four years -- giving some 20,000 megawatts (MW) of installed capacity.
While such comparisons are not precise, in the US, 1MW of wind power generates about as much electricity as 240-300 homes use, according to the American Wind Energy Association.
Currently, Spain, where the energy market was deregulated in 1998, is second only to Germany and just ahead of the US in terms of installed wind power capacity, at 8,155MW in December 2004, compared with 14,000MW for Germany.
Analysts say Chinese capacity could hit 30 gigawatts (GW or 30,000MW) by 2020, underscoring Spanish interest in that market.
Solar power is also on the rise, with Spain's photovoltaic association ASIF forecasting growth of up to 1,100MW by 2010, exceeding government forecasts more than twice over.
Spain's first polysilicon solar plant came on stream only last month on the outskirts of the southern city of Cadiz.
Iberdrola, Spain's second largest indigenous producer of electricity, said on Thursday that a surge in its renewable energy business had helped lift first-half net profit by 25 percent to 817.8 million euros (US$1 billion), well above forecasts.
Earlier, the firm announced it had raised its stake in the Spanish wind farm specialist Gamesa to 17 percent as part of a move to focus its interests on renewable sources.
According to financial director Jose Sainz Armada, Iberdrola expects production at its renewable energy division to grow "by 10-12 percent in the second half of this year."
The wind generated portion of the firm's energy output is barely 14 percent of the 27,993MW total at present, but Iberdrola says the target is to lift that to nearer 33 percent for a total 10,000MW by 2011.
The link up with Gamesa "is seen as an important plank in a renewables strategy whose growing importance cannot be underestimated," an energy analyst at a leading European bank said on Friday.
Gamesa has become a trailblazer in recent years, exporting its wind technology to China, the US and France.
The company is the second-biggest producer of wind turbines in the world behind Danish rival Vestas Wind Systems and won orders last year to install 520 wind turbines worth 234 million euros.
More than half of those were from China, where Gamesa already covers 36 percent of the renewable energy market.
Iberdrola itself recently bought out US operator Community Energy (CEI) and agreed to take a 29 percent stake in China's Guanxi Guidong Electric.
The Spanish group is also tackling renewables projects from Britain to Brazil and has 16,000MW worth of projects in China, the US and France alone.
"That makes us the biggest wind energy producer in the world," the firm claims.
Regarding nuclear power, Spain has nine plants in operation that account for 23 percent of all energy production, a level comparable with the US and Britain but far behind France's 78 percent.
Increasing that level however is a political hot potato, as elsewhere.
Britain's energy review last week flagged the need to develop renewable sources although Prime Minister Tony Blair said in May that nuclear energy was "back on the agenda with a vengeance" amid the need to slash greenhouse gas emissions by 20 percent of their 1990 levels between now and 2010.
Spain, which depends heavily on imported supplies of oil and gas, last year unveiled a Renewable Energy Plan.
The plan offers tax incentives for firms that employ clean emission technologies, and sees 97 percent of a total 23.6 billion euro investment coming from the private sector.
While not all environmentalists are convinced, wildlife officials at a bird sanctuary in the Ebro Delta were appalled to hear of a wind farm project for the area, a 2003 Greenpeace (France) report favorably compared the wind route with the prospect of greater reliance on nuclear power.
That report quoted the European Wind Energy Association as saying that by 2010, installed wind capacity could equal the output of 14 nuclear reactors.
In a world which uses more than 300 billion kilowatt-hours of energy a day and rising, the rush to renewables shows no sign of abating.
"Renewable sources can help to bridge the gap in the European energy supply ... and contribute to sustainable development," a report by the EU Barometer of Renewable Energies said recently.
AGING: As of last month, people aged 65 or older accounted for 20.06 percent of the total population and the number of couples who got married fell by 18,685 from 2024 Taiwan has surpassed South Korea as the country least willing to have children, with an annual crude birthrate of 4.62 per 1,000 people, Ministry of the Interior data showed yesterday. The nation was previously ranked the second-lowest country in terms of total fertility rate, or the average number of children a woman has in her lifetime. However, South Korea’s fertility rate began to recover from 2023, with total fertility rate rising from 0.72 and estimated to reach 0.82 to 0.85 by last year, and the crude birthrate projected at 6.7 per 1,000 people. Japan’s crude birthrate was projected to fall below six,
Conflict with Taiwan could leave China with “massive economic disruption, catastrophic military losses, significant social unrest, and devastating sanctions,” a US think tank said in a report released on Monday. The German Marshall Fund released a report titled If China Attacks Taiwan: The Consequences for China of “Minor Conflict” and “Major War” Scenarios. The report details the “massive” economic, military, social and international costs to China in the event of a minor conflict or major war with Taiwan, estimating that the Chinese People’s Liberation Army (PLA) could sustain losses of more than half of its active-duty ground forces, including 100,000 troops.

US President Donald Trump in an interview with the New York Times published on Thursday said that “it’s up to” Chinese President Xi Jinping (習近平) what China does on Taiwan, but that he would be “very unhappy” with a change in the “status quo.” “He [Xi] considers it to be a part of China, and that’s up to him what he’s going to be doing, but I’ve expressed to him that I would be very unhappy if he did that, and I don’t think he’ll do that. I hope he doesn’t do that,” Trump said. Trump made the comments in the context
SELF-DEFENSE: Tokyo has accelerated its spending goal and its defense minister said the nation needs to discuss whether it should develop nuclear-powered submarines China is ramping up objections to what it sees as Japan’s desire to acquire nuclear weapons, despite Tokyo’s longstanding renunciation of such arms, deepening another fissure in the two neighbors’ increasingly tense ties. In what appears to be a concerted effort, China’s foreign and defense ministries issued statements on Thursday condemning alleged remilitarism efforts by Tokyo. The remarks came as two of the country’s top think tanks jointly issued a 29-page report framing actions by “right-wing forces” in Japan as posing a “serious threat” to world peace. While that report did not define “right-wing forces,” the Chinese Ministry of Foreign Affairs was
