What is energy technology?
Energy technology concerns development systems capable of producing, transporting and supplying energy in a way that is safe, economical and increasingly environmentally friendly. Generally speaking, it is a field of many overlapping disciplines. Hard sciences such as physics and chemistry are essential for understanding where energy can be available. Engineering disciplines are obliged to design systems that use energy. Finally, environmental science is used to measure the impact of energy technology on the natural world.
Some of the first energy technologies have been designed to extract energy from the fire. Burning fuel, which could be wood, coal or oil, produces heat - a form of energy. The use of this heat to boil water creates steam. In the steamer, this steam is used to push the piston and turn the crankshaft, which is a form of mechanical energy. This rotary movement can be used for power machines in the factory or to turn the propeller on the Ship.
in the factMost of the energy technology applications for transport purposes use the same basic process. Steam ships revolutionized the transport methods during the first industrial revolution and later began to replace the sail -powered vessels as primary warships. These steam ships used coal as fuel. During the second industrial revolution, transport energy technology began to use oil as primary fuel. Motors with internal oil -based combustion are used in every country of the world for transport applications.
In 1881, electricity was first produced at the central station and delivered to other places. Electricity is the flow of electrically charged particles; These particles can carry energy with them in a way that is analogous water pressure. Energy transport to other places is therefore an electricity function.
Any energy source can be converted into electricity using energy technology. Sources of electricity inThe United States includes coal, natural gas and nuclear energy. Electricity and transportation sources of transport often differ due to different requirements for each application. Electric power plants must be very effective in making as much electricity as possible. On the other hand, transport energy systems can get away with less fuel efficiency, as they must also be small and light enough to fit into the vehicles.
growing concern is the development of alternative energy sources. Coal, oil and natural gas are all non -renewable energy sources, which means that they exist in the end on the ground and one day could be used. Coal and oil burning has negative environmental effects that are also a growing problem. Energy technology is monitored to develop clean, efficient and renewable energy sources for application for electricity and transportation.
