How might the answer to this question unfold? The question we need to ask ourselves is: “How can we abandon fossil fuels before their use causes further problems?” The answer to this question will be to find an effective and possible way to use renewable energy, such as solar energy, wind energy.12.5 Nuclear is getting a second lookWhat is the difference between fission and fusion? Which one do we use in nuclear power plants? Fission is a nuclear reaction in which a neutron strikes a relatively large attic nucleus. Fusion occurs when lighter nuclei are forced together to produce heavier nuclei. We use fission in nuclear power plantsWorking towards sustainability: here's TED: The Energy DetectiveHow feedback can change energy
