Energy and Power Technologies  Energy  Energy is defined as the ability to do work

Energy and Power Technologies  Energy  Forms of energy  Light  Heat  Mechanical  Chemical  Electrical  Nuclear

Energy and Power Technologies  Energy Sources  Nonrenewable Energy  Fossil Fuels  Natural Gas  Coal  Petroleum  Nuclear Electric Power  Renewable Energy  Solar  Biomass  Geothermal  Hydroelectric  Wind

Energy and Power Technologies  Energy Sources

Energy and Power Technologies  Work  Work is the application of a force over a distance. Work is equal to the product of the force and the distance through which it produces movement W = Fd

Energy and Power Technologies  Power  Power is defined as the rate at which work is performed or energy is expended P = ∆W/∆t

Energy and Power Technologies  Power  Three major forms of power  Electrical Power  Mechanical Power  Fluid Power

Energy and Power Technologies  Science vs. Technology  Science is the body of knowledge related to the natural world and its phenomena  Technology is the body of knowledge related to the human- made world. The technological world includes human-made products and their impacts to society and the environment

Energy and Power Technologies  Science vs. Technology

Energy and Power Technologies  Technological Systems  System involves a combination of related parts working together  Inputs of a system are the resources needed to begin the system  People  Capital  Knowledge  Material  Energy  Time  Finance

Energy and Power Technologies  Technological Systems  Processes is the portion of technological systems that are changing the inputs to produce outputs (result). Processes must always be managed, in one way or another, by humans  Outputs are the end results of the technological system. The creation of an output can also cause the creation of undesirable outputs, which, must always be factored into the input of the technological system  Goals are the successful completion of a technological system  Societies put restrictions on technological systems through regulations
