With rising demand for energy, especially electricity, the world is in need of new resources. Fossil fuels produce harmful carbon emissions and green technology may never be able to provide a reliable source of renewable energy. Despite ongoing concerns about the safety of nuclear power, it's likely going to play an increasingly large role in satisfying our needs. Several projects being developed in Russia will hopefully help make nuclear's enlarged role as safe as possible. Fast neutron reactors look to be the future of the industry, while an advanced gas-cooled reactor design could have benefits beyond electricity generation. And Russia's plans for a fleet of floating nuclear power stations will bring electricity, heat and fresh water to isolated populations.
