At 350.org we work towards replacing dirty fossil fuels with clean and renewable energy, not nuclear power. Even after decades of extensive government subsidy, the cost of nuclear power remains dauntingly high, in part because the potential of catastrophic accident requires the commitment to truly massive building projects. The cost of wind and especially sun are decreasing on an almost daily basis: solar panels down 75% in the last seven years. Meanwhile, the costs of nuclear power just keep rising, and its problems mirror those of fossil fuels: extractive mining, waste management issues, and a centralization of power. Conservation and renewables continue to be a far preferable strategy to addressing the climate crisis.
