This course will introduce Energy history and Taiwan fossil fuel, Coal, Petroleum, natural gas, shale oil and bitumen sand, Gas Hydrate, Nuclear energy, Solar energy, Wind energy, geothermal power, Biothanol, Biodiesel, Fuel cell, Hydrogen energy, Global warming, Air pollution, Heat Island Effect. We emphasize following aspects: (1) Understanding the relationship of energy and power in life, further learning the corresponding knowledge are the objectives of the course. (2) Using the least amount of energy resources to minimize the burden on the environment and established to aim to improve energy efficiency in end-use sectors and to increase the diversity of energy resources consistent with an economically and environmentally sustainable future. (3) Hydrogen and fuel cell, such as proton exchange membrane fuel cell, direct methanol fuel cell, solid oxide fuel cell, and renewable hydrogen. Renewable energy, such as solar cell, wind power, and biomass; energy storage such as Li-Ion battery; advanced power management, such as high-efficient converter and inverter; energy-saving technology in manufacture. Furthermore, new developed power technologies are also introduced.
