Los senderos hacia una energía sustentable

NUEVA YORK – La apuesta más segura sobre el futuro de la energía es la necesidad de suministros energéticos reducidos en carbono. Aproximadamente el 80% de la energía primaria del mundo hoy está basado en el carbono: carbón, petróleo y gas. Vamos a necesitar pasar a energía sin carbono o baja en carbono para mediados de siglo. Los grandes interrogantes son cómo y cuándo.

La energía primaria con bajo contenido de carbono implica tres opciones: energía renovable, que incluye energía eólica, solar, geotermal, hidráulica y biomasa; energía nuclear, y captura y almacenamiento de carbono, que significa utilizar combustibles fósiles para crear energía, atrapando a la vez las emisiones de CO2 que resultan y guardando el carbono de manera segura bajo tierra.

Existen tres razones imperiosas para que el mundo adopte una energía reducida en carbono. Primero, los niveles más elevados de CO2 están acidificando los océanos. Si seguimos haciendo las cosas como hasta ahora, terminaremos destruyendo una enorme cantidad de vida marina, dañando seriamente las cadenas alimenticias de las que dependemos.

    The Brexit Surrender

    European Union leaders meeting in Brussels have given the go-ahead to talks with Britain on post-Brexit trade relations.

  3. Murdoch's Last Stand?

    Rupert Murdoch’s sale of 21st Century Fox’s entertainment assets to Disney for $66 billion may mark the end of the media mogul’s career, which will long be remembered for its corrosive effect on democratic discourse on both sides of the Atlantic. 

    From enabling the rise of Donald Trump to hacking the telephone of a murdered British schoolgirl, Murdoch’s media empire has staked its success on stoking populist rage.

    The Dangerous Delusion of Price Stability

    Since the hyperinflation of the 1970s, which central banks were right to combat by whatever means necessary, maintaining positive but low inflation has become a monetary-policy obsession. But, because the world economy has changed dramatically since then, central bankers have started to miss the monetary-policy forest for the trees.

  5. Harvard’s Jeffrey Frankel Measures the GOP’s Tax Plan

    Jeffrey Frankel, a professor at Harvard University’s Kennedy School of Government and a former member of President Bill Clinton’s Council of Economic Advisers, outlines the five criteria he uses to judge the efficacy of tax reform efforts. And in his view, the US Republicans’ most recent offering fails miserably.

    The Holy Grail of Genetic Engineering

    CRISPR-Cas – a gene-editing technique that is far more precise and efficient than any that has come before it – is poised to change the world. But ensuring that those changes are positive – helping to fight tumors and mosquito-borne illnesses, for example – will require scientists to apply the utmost caution.
