Greenpeace Central & Eastern Europe activist Zoran Tomic at Drenovci school. Solar panels will be used to power the IT department following a screening of a World Cup game between Croatia and Brazil, the first game of World Cup. The screening will be powered entirely by solar power. The solar panels are installed onto the local school in Drenovci, a village severely affected by recent floods. Greenpeace demands that the reconstruction of the region is done with an energy efficient way. More than 90 percent of Croatian people think the country should use more renewable energy.
