O renascimento da energia nuclear em sentido inverso

PARIS – No passado mês de Junho, Yukiya Amano, director-geral da Agência Internacional de Energia Atómica (AIEA), declarou que "a energia nuclear contribuirá de forma significativa e crescente para o desenvolvimento sustentável nas próximas décadas." Contudo, de acordo com World Nuclear Industry Status Report (Relatório sobre a Situação da Indústria Nuclear no Mundo, ndt.) deste ano, as tendências recentes apresentam um quadro muito diferente.

A Duke Energy, a maior empresa americana de abastecimento de energia, suspendeu os planos de construção de dois reactores na Flórida, após ter gasto mil milhões de dólares no projecto. A decisão foi tomada apenas três meses após a empresa ter abandonado o investimento em duas novas unidades na Carolina do Norte.

Na verdade, este ano, quatro empresas americanas de abastecimento de energia decidiram encerrar permanentemente um total de cinco reactores - os primeiros encerramentos verificados nos Estados Unidos em 15 anos. Uma das unidades - a Central Nuclear de Kewaunee em Wisconsin - foi abandonada após um investimento maciço em matéria de modernizações e uma renovação da licença por 60 anos; não tinha forma de produzir energia a preços competitivos. Pelas mesmas razões, a Vermont Yankee, outra central com uma licença para operar até 2032, tem o encerramento previsto para 2014.

    Populist Plutocracy and the Future of America

    • In the first year of his presidency, Donald Trump has consistently sold out the blue-collar, socially conservative whites who brought him to power, while pursuing policies to enrich his fellow plutocrats. 

    • Sooner or later, Trump's core supporters will wake up to this fact, so it is worth asking how far he might go to keep them on his side.

    The Man Who Didn’t Save the World

    A Saudi prince has been revealed to be the buyer of Leonardo da Vinci's "Salvator Mundi," for which he spent $450.3 million. Had he given the money to the poor, as the subject of the painting instructed another rich man, he could have restored eyesight to nine million people, or enabled 13 million families to grow 50% more food.

    Two Myths About Automation

    While many people believe that technological progress and job destruction are accelerating dramatically, there is no evidence of either trend. In reality, total factor productivity, the best summary measure of the pace of technical change, has been stagnating since 2005 in the US and across the advanced-country world.

    The Hungarian Government’s Failed Campaign of Lies

    The Hungarian government has released the results of its "national consultation" on what it calls the "Soros Plan" to flood the country with Muslim migrants and refugees. But no such plan exists, only a taxpayer-funded propaganda campaign to help a corrupt administration deflect attention from its failure to fulfill Hungarians’ aspirations.
