Portugal Gives Itself a Clean-Energy Makeover
By Elisabeth Rosenthal
LISBON — Five years ago, the leaders of this sun-scorched, wind-swept nation made a bet: To reduce Portugal’s dependence on imported fossil fuels, they embarked on an array of ambitious renewable energy projects — primarily harnessing the country’s wind and hydropower, but also its sunlight and ocean waves .
Today, Lisbon’s trendy bars, Porto’s factories and the Algarve’s glamorous resorts are powered substantially by clean energy. Nearly 45 percent of the electricity in Portugal’s grid will come from renewable sources this year, up from 17 percent just five years ago.
Land-based wind power — this year deemed “potentially competitive” with fossil fuels by the International Energy Agency in Paris — has expanded sevenfold in that time. And Portugal expects in 2011 to become the first country to inaugurate a national network of charging stations for electric cars.
“I’ve seen all the smiles — you know: It’s a good dream. It can’t compete. It’s too expensive,” said Prime Minister José Sócrates, recalling the way Silvio Berlusconi, the Italian prime minister, mockingly offered to build him an electric Ferrari. Mr. Sócrates added, “The experience of Portugal shows that it is possible to make these changes in a very short time.”
The oil spill in the Gulf of Mexico has renewed questions about the risks and unpredictable costs of America’s unremitting dependence on fossil fuels. President Obama has seized on the opportunity to promote his goal of having 20 to 25 percent of America’s electricity produced from renewable sources by 2025.
While Portugal’s experience shows that rapid progress is achievable, it also highlights the price of such a transition. Portuguese households have long paid about twice what Americans pay for electricity, and prices have risen 15 percent in the last five years, probably partly because of the renewable energy program, the International Energy Agency says.
Although a 2009 report by the agency called Portugal’s renewable energy transition a “remarkable success,” it added, “It is not fully clear that their costs, both financial and economic, as well as their impact on final consumer energy prices, are well understood and appreciated" (...) .in the New York Times- 9 de Agosto de 2010 *
