Hi, I'm new to this forum. I'm doing a self-taught course on physics and I've been given a research topic of coal-fired generation of electricity. I'm supposed to answer the following questions: 1. An explanation of the physics involved in the energy production, including the application of the law of conservation of energy 2. Two advantages and two disadvantages of the method of production 3. An analysis of the economic viability of the process. I'm sure I can answer number 2 with no problem, however, questions 1 and 3 are difficult to find. I'm supposed to use the Internet to answer these questions, but my search engine is not giving me any relevant information on this topic in regards to physics. There was another part to this question where it asked the same questions in regards to tidal energy. I was wondering if the answers for tidal energy, is similar to the answers I would be getting for coal-fired generation of electricity? From what I've read about coal, the ending seems similar to the reuse of kinetic energy that tidal waves use. But I'm not too sure. If someone could help me on this, that would be great! Thanks.
