Énergie solaire
L’énergie solaire est l’énergie que dispense le soleil par son rayonnement, directement ou de manière diffuse à travers l’atmosphère. Grâce à divers procédés, elle peut être transformée en une autre forme d’énergie utile pour l’activité humaine, notamment en chaleur, en électricité ou en biomasse. Par extension, l’expression « énergie solaire » est souvent employée pour désigner l’électricité ou la chaleur obtenue à partir de cette dernière.

As I write this piece, were in the midst of a (biodiesel) road trip to Washington, D.C., towing behind us an unwieldy piece of history: a solar panel off the roof of the Carter White House. Its decades old, though it still makes hot water just fine. In a sense, were traveling backwardwhich in another sense is what I think were going to have to do for a while in the U.S. climate movement.
For a few days last week, global news agencies pursued the peculiar story of the world's worst traffic jam, which was reported to have lasted for around nine days and stretched across about 100 kilometres of a major highway leading to Beijing. China's latest instance of leading the world, now in the scale and size of traffic jams, is a direct consequence of the modern uses and abuses of energy.
The backyard organic gardens central to the current series of posts on The Archdruid Report -- and equally central to most strategies for relocation in the face of looming energy shortages -- have a lot of work to do in the period between the last frosts of spring and the first frosts of fall. Stretching that interval, by way of "time machines" drawn from appropriate technology, can help make growing part of one's own food a more viable proposition.

As elsewhere in western Europe, the advanced liberal consumer democracies are ever more unable (politically unwilling) to implement genuine change. Deutschland's rulers in Berlin firmly believe that techno-managerial innovation (and a hefty dose of financial risk-taking) will continue to provide cures for current ideas of what is unsustainable. As has happened time and again in Europa's history of nations, from the mid-19th century onwards, the costs of such 'revolutions' will be externalised elsewhere (east and south), and the ecological sustainability that Germany's admirable network of communes have long been admired for will remain out of reach of the country's policy and practice.

Now that I'm retired from the academic life -- or rather, now that I've departed the academy in disgust and despair -- I no longer spend time in my swivel chair, dispensing information on the telephone or tending to the tender young psyche of an overwrought twenty-something.
