Which of the following statements best compares nuclear power and hydropower based on their rates of renewal? Hydropower has a faster rate because water is continuously being recycled through the hydrogeological cycle. Nuclear power has a faster rate because all elements are spontaneously radioactive and are a source of nuclear energy. Hydropower has a slower rate because a large volume of water vapor that evaporates takes several years to return to water cycle. Nuclear power has a slower rate because the nuclear waste produced is not radioactive and thus cannot be used further as a fuel
