By now, the heartbreaking photos of neighborhoods swept to sea and a climbing death toll have reminded us all of the immeasurable pain and tragedy our environment can incur. We think of the millions of people who continue to be affected by the storm, the tens of thousands who have lost all that they own, and the hundreds who have lost their lives.

Sandy also tells us a lot about ourselves. From a pessimistic standpoint, it shows human failure: our failure to listen to those who understand far better than most of us do the impact of human behavior on the atmosphere, our climate system, and the ecosystems that surround us. While it is true that no singular weather event can be directly linked to human-caused global warming, the Intergovernmental Panel on Climate Change – since its establishment in 1988 arguably the most thorough and meticulous scientific undertaking in human history – has reported with increasing confidence that weather extremes will become more frequent, more widespread, and more intense with rising greenhouse gas emissions. The IPCC’s assessments, and those of many other leading scientific bodies, have led prominent commentators—among them Nobel laureates, prime ministers, presidents, secretary-generals, and even movie stars—to call out global warming as this century’s greatest threat. But Sandy demonstrates in dramatic fashion our inability to take more profound steps to tackle global challenges, despite our knowledge that we endanger ourselves if we don’t. Sandy reveals our refusal to take responsibility for our actions and our skepticism that real change (of natural systems as well as of our own behavior) is possible. Continue reading »

Small Portugal Thinks Big – and Very Green!

After having shed some light on French climate and energy legislation, let’s proceed with our review of European progress toward clean energy economies. Typically, the Scandinavian countries and Germany have set the example in the European renewables field. Yet lately, a Southern country—Portugal—has attracted media attention after delivering its National Renewable Energy Action Plan to the European Commission this June.

Portugal has made dramatic changes in its energy policy over the last five years under the government of Prime Minister Jose Socrates. The country’s installed renewable energy capacity more than tripled between 2004 and 2009, from 1,220 megawatts (MW) to 4,307 MW, and renewables now represent roughly 36 percent of electricity consumed. Thanks to this performance, Portugal currently ranks 4th in Europe in energy production from renewables. Socrates seems to know what he is doing, and it looks like his previous experience has paid off. Like Germany’s chancellor Angela Merkel, Socrates was Minister of the Environment before becoming head of his country’s government. The environment seems to be a springboard for European politicians’ careers.

Of course, Portugal benefits from favorable conditions for renewables as well: a strong wind resource, great hydropower, good tidal waves potential, and a high sunshine rate. After the country removed several dams in recent years, Socrates’ government has focused instead on wind power development, under most conditions the cheapest renewable energy source after hydropower. With spectacular growth in wind energy production of over 600 percent between 2004 and 2009, Portugal now ranks 6th in Europe in total installed capacity and 3rd in capacity per capita, behind only Denmark and Spain. Some even expect Portugal to overtake its neighbor Spain in per capita wind energy production as early as this year.
