Cleantech expo shows how Switzerland could cope without nuclear power

In the wake of Japan's earthquake, which caused a nuclear power plant meltdown, Switzerland decided to opt out of nuclear power and focus on promoting renewable energies. A cleantech conference in Bern, showcasing pioneering technologies in the fields of energy production, construction, water, waste disposal and mobility, demonstrates that the market is already responding to demands for a greener future.
