La culture de l'énergie

Du réchauffement climatique à l'instabilité des prix du pétrole, tout indique qu'une crise énergétique mondiale semble sur le point de se produire. Pour relever ce défi, l'humanité ne peut plus se permettre d'ignorer l'inépuisable ressource des matériaux biologiques que le soleil fournit chaque jour par le biais de la photosynthèse. L'énergie solaire permet aux plantes d'absorber le carbone et ainsi de produire non seulement de l'oxygène, mais aussi de la matière que le règne animal utilise pour se nourrir, et que nos machines peuvent utiliser pour obtenir de l'énergie.

Depuis le Néolithique, les humains cultivent cette biomasse pour se nourrir. À notre époque encore, son potentiel énergétique reste ignoré. À partir de la révolution industrielle, les humains ont recherché l'énergie dans le charbon, et plus tard dans le pétrole et le gaz naturel, ce qui conduit à l'épuisement de ressources qui ne sont pas renouvelables.

Les alternatives visant à diversifier la production d'énergie sont limitées. L'énergie nucléaire présente un certain nombre d'inconvénients, notamment en termes de sécurité et de déchets radioactifs. L'énergie hydroélectrique est déjà largement utilisée, quant aux énergies éolienne et solaire, elles sont structurellement sporadiques et disponibles de façon inégale.

    Empowering China’s New Miracle Workers

    China’s success in the next five years will depend largely on how well the government manages the tensions underlying its complex agenda. In particular, China’s leaders will need to balance a muscular Communist Party, setting standards and protecting the public interest, with an empowered market, driving the economy into the future.

    The Sovereignty that Really Matters

    The preference of some countries to isolate themselves within their borders is anachronistic and self-defeating, but it would be a serious mistake for others, fearing contagion, to respond by imposing strict isolation. Even in states that have succumbed to reductionist discourses, much of the population has not.

    Resurrecting Creditor Adjustment

    When the Bretton Woods Agreement was hashed out in 1944, it was agreed that countries with current-account deficits should be able to limit temporarily purchases of goods from countries running surpluses. In the ensuing 73 years, the so-called "scarce-currency clause" has been largely forgotten; but it may be time to bring it back.

    Trump’s Republican Collaborators

    Republican leaders have a choice: they can either continue to collaborate with President Donald Trump, thereby courting disaster, or they can renounce him, finally putting their country’s democracy ahead of loyalty to their party tribe. They are hardly the first politicians to face such a decision.

    How Money Could Unblock the Brexit Talks

    With talks on the UK's withdrawal from the EU stalled, negotiators should shift to the temporary “transition” Prime Minister Theresa May officially requested last month. Above all, the negotiators should focus immediately on the British budget contributions that will be required to make an orderly transition possible.

    Is Vladimir Putin Losing His Grip?

    In recent decades, as President Vladimir Putin has entrenched his authority, Russia has seemed to be moving backward socially and economically. But while the Kremlin knows that it must reverse this trajectory, genuine reform would be incompatible with the kleptocratic character of Putin’s regime.

    Don’t Bank on Bankruptcy for Banks

    As a part of their efforts to roll back the 2010 Dodd-Frank Act, congressional Republicans have approved a measure that would have courts, rather than regulators, oversee megabank bankruptcies. It is now up to the Trump administration to decide if it wants to set the stage for a repeat of the Lehman Brothers collapse in 2008.
