La voie vers une énergie durable

NEW YORK – Une chose est sûre à propos de l’avenir de l’énergie : il faudra trouver des sources d’énergie à faible émission de carbone. Près de 80 pour cent de l’énergie primaire mondiale est aujourd’hui à base de carbone : charbon, pétrole et gaz naturel. D’ici le milieu du siècle, nous devrons avoir effectué la transition vers une énergie à faible ou nulle intensité carbonique. Les deux grandes questions sont comment et quand.

Une énergie à faible intensité carbonique implique trois options : les énergies renouvelables, éolienne, solaire, géothermique, hydraulique et à partir de la biomasse ; l’énergie nucléaire ; et le captage et la séquestration de carbone, c’est-à-dire utiliser les combustibles fossiles pour créer de l’énergie, mais capter les émissions de dioxyde de carbone (CO2) qui en résulte et les stocker sous terre.

Trois raisons impérieuses nous obligent à effectuer la transition vers une énergie à faible intensité carbonique. Premièrement, les taux élevés de CO2 provoquent une acidification des océans. Continuer comme si de rien n’était implique une destruction massive de la vie marine, avec des conséquences dévastatrices sur les chaînes alimentaires dont nous dépendons.

    The Next Battle in China’s War on Corruption

    • Chinese President Xi Jinping knows well the threat that corruption poses to the authority of the Communist Party of China and the state it controls. 
    • But moving beyond Xi's anti-corruption purge to build robust and lasting anti-graft institutions will not be easy, owing to enduring opportunities for bureaucratic capture.

    Putting Europe’s Long-Term Unemployed Back to Work

    Across the European Union, millions of people who are willing and able to work have been unemployed for a year or longer, at great cost to social cohesion and political stability. If the EU is serious about stopping the rise of populism, it will need to do more to ensure that labor markets are working for everyone.

    A Belt and Road for the Americas?

    In a time of global uncertainty, a vision of “made in the Americas” prosperity provides a unifying agenda for the continent. If implemented, the US could reassert its historical leadership among a group of countries that share its fundamental values, as well as an interest in inclusive economic growth and rising living standards.

    How Best to Promote Research and Development

    Clearly, there is something appealing about a start-up-based innovation strategy: it feels democratic, accessible, and so California. But it is definitely not the only way to boost research and development, or even the main way, and it is certainly not the way most major innovations in the US came about during the twentieth century.

    Preparing for the Trump Trade Wars

    In the first 11 months of his presidency, Donald Trump has failed to back up his words – or tweets – with action on a variety of fronts. But the rest of the world's governments, and particularly those in Asia and Europe, would be mistaken to assume that he won't follow through on his promised "America First" trade agenda.
