Main definitions and laws used to estimate the energy content of different systems. Study of energy consumption mechanisms in systems including cars, planes, heating/cooling, lighting, gadgets, and food/farming. Study of sustainable energy production methods including wind, solar, hydroelectricity, offshore wind, wave, tide, geothermal and nuclear. A balance sheet will be put together in order to answer the question: "Can we conceivably live sustainably without the need for fossil fuels?"
