Background

Ames Hydroelectric Generating Plant

Energy and powered devices are an integral part of society. Humanity's earliest days saw the discovery of fire through wood combustion, and the use of charcoal for smelting metals dates back as early as 5000 BC. Powered devices using natural energy sources such as water and wind were introduced by the Ancient Greeks and were commonly used until the 18th century steam engine revolutionized the way devices could be powered. Various natural oils were used for a range of purposes, such as whale oil for lamps. The Industrial Revolution led to the massive use of coal as fuel, and the extraction of petroleum and various other oils became extremely important with the advent of internal combustion engines. Electrical power, also based on fossil fuels, became widespread at the end of the 19th century and the production of cleaner electrical energy through nuclear, hydropower, geothermal, and solar means is a topic even more relevant to today's world.
