Vuelve la energía nuclear, porque el petróleo se ha vuelto muy caro y recalentón mental de la progresía hace imposible el uso de carbón, del que hay reservas para siglos. Las energías renovables, carísimas, NO son una alternativa razonable.
El artículo es una buena lectura. Trata de el problema que los alemanes se han buscado ellos solitos al decidir socialistas y verdes desconectar todas sus siete centrales nucleares entre 2010 y 2012. Ni Zapatero se atrevería (espero). Solo os voy a traer frases sueltas:
Despite a decade of massive investment and generous programs established to promote wind [en Alemania], solar and biomass power generation, green energy sources make up just 14 percent of the country’s energy supply.
Después de un decenio de generosas inversiones, las fuentes de energía verde solo alcanzan el 14% del consumo.
After decades of hesitancy, more and more countries are turning back toward the atom with well over 100 reactors either already under construction or in the planning stages.
Hay más de 100 reactores en construcción planificación en el mundo.
Russia is planning to build some 30 new coal-fired plants by 2011. In China, a new coal-fired facility goes on line about once every 10 days.
Los chinos están poniendo en funcionameinto un horno de carbón cada 10 dias, no dicen su potencia, pero… Ya podemos limitar nuestras emisiones.
Still, it is nuclear power that many are beginning to see as the planet’s saviour. A typical coal-fired power plant (burning lignite) emits up to 1,150 grams of CO2 per kilowatt hour of electricity produced. The most modern gas-driven facilities emit 400 grams for the same amount of electricity. And for nuclear power plants? That number is around 30 grams per kilowatt hour when the entire life-cycle of the plant is taken into account.
After a 30 year gap with not a single new reactor being connected to the US power grid, four projects are now under review with up to 30 more in the planning stages. Bush’s Energy Secretary Samuel Bodman recently demanded even more. «We don’t need 30 of these additional units, we need 130 or 230,» he said. John McCain, the Republican candidate for the White House, has likewise suggested that the US alone should build over 100 new nuclear power facilities.
Estados Unidos reanuda la construcción de centrales tras 30 años de parón nuclear. No es el único:
The US is far from alone. French President Nicolas Sarkozy, like many in his country, long a proponent of nuclear power, called atomic power «more than ever an industry of the future» last week while announcing the construction of yet another nuclear reactor — his country’s 61st. In Great Britain, Prime Minister Gordon Brown would like to see 40 percent of the UK’s energy coming from nuclear power — requiring the construction of 20 new reactors. Switzerland is planning three new reactors. A number of countries in Eastern Europe want more atomic power. Russia is considering up to 35 new reactors.
Pero el problema de los residuos no está resuelto:
Plus, one of the enduring challenges of nuclear power remains to be solved: what to do with the highly radioactive waste produced by atomic reactors? In the last 50 years of nuclear power generation, some 300,000 tons of the stuff has been produced, with an additional 10,000 tons coming each year. A part of that waste is plutonium, and it is incredibly volatile. Just a single gram contains as much energy as a ton of oil — and it can give hundreds of people cancer should it be inhaled as radioactive dust. Should one stand next to a gram of plutonium for just a single minute, death is the result.
Al fin y al cabo todo es cuestión de inversiones y de dinero, y la energía nuclear es muy, muy rentable:
The reactors at Biblis, for example, make a pre-tax profit of €1 million — every single day.
