al cabinet is expected to make a final decision about the future of nuclear energy at a meeting June 6. The main features of its new energy policy, however, are clear after last night's meeting. At 0817 GMT RWE shares traded lower EUR1 or 2.4% at EUR40.25, while E.ON shares fell EUR0.36 or 1.85 to EUR19.66. Both shares underperformed a broadly firmer market. On Sunday night, Environment Minister Norbert Roettgen announced to reporters following a meeting with German Chancellor Angela Merkel that Germany would end the use of nuclear energy by 2022 at the very latest. The country's seven oldest nuclear reactors, which have been shut down since mid-March, will never resume power generation, the government said. An eighth power plant--the 1.4-gigawatt reactor Kruemmel that has been glitch-prone and offline for the best part of three years--will also be shut down permanently. The remaining reactors--except for three that will be kept as reserve capacity for an additional year to ensure that energy demand can be met--will be shut down by 2021. The government also said that it plans to keep the new tax on nuclear fuel rods that was introduced at the beginning of the year. The tax is expected to generate proceeds of around EUR2.3 billion per year and was officially introduced to help plug public budget holes. Many observers, however, have also linked the tax to the extension of reactor operating lives, for which the power plant operators had tost stop, a walking tour of a destroyed neighborhood. A memorial service later was punctuating a day of remembrance and toil as authorities pressed on with the tasks of poking through wreckage and identifying the dead. Obama returned Saturday from a six-day European tour of Ireland, Britain, France and Poland. After days of focusing on the U.S. relationship with the rest of the world, he turned to an even more critical connection: his own, with the American people.  He was visiting survivors and the bereaved from the worst tornado in decades, in what has racked up to be the deadliest tornado season in more than 50 years. As Air Force One swept over the landscape, flattened houses and stripped trees offered a massive swath of brown. Looking around the neighborhood by foot, Obama eyed boarded-up windows, damaged business signs, fallen trees, piles of debris and homes spray-painted with "God Bless Everyone"  With dozens still missing, homes marked with an X meant they had been searched already for missing loved ones.  Speaking to the press after his tour, Obama said the "scene speaks for itself." He pledged that the tragedy isn't just one for the community, but one the nation will share. "And there will be a national response," he said.  Sunday's task
