All About Energy
What is it?!?
Power: The quantity of work that has to do with a force causing a displacement
Electricity: A form of energy resulting from the existence of charged particles (electrons or protons), either statically as an accumulation of charge or dynamically as a current
Electromagnetic Induction: occurs when a circuit with an alternating current flows through and generates current in another circuit simply by being placed nearby it
Energy Efficiency: is the ratio between the useful output of an energy conversion machine and the input
Power Pools: are entities where electric utilities and power producers may combine the output of electric generating resources and sell the combined output
Load Management: is the process of balancing the supply of electricity on the network with the electrical load by adjusting or controlling the load rather than the power station output
Generator: is a device that is used to move electrons through a conductor to give electric power. Through the power of a generator, the electrons can transmit electric energy from one point to another quickly and efficiently.
What's the Difference?!?
Renewable Energy & Nonrenewable Energy: Renewable energy is energy which comes from natural resources such as sunlight, wind, rain, tides, and geothermal heat, which are naturally replenished. Nonrenewable energy however is a natural resource which cannot be produced, grown, or generated. This form of energy is on a scale which cannot sustain its consumption rate. These resources often exist in a fixed amount, or are consumed much faster than nature can create them.
Dry Production, Flash Production, & Binary Production: Dry production is the growth of natural substances that do not have anything mixed into them, such as dry gas, it is essentially just gas besides the methane. Flash production is the use of steam plants to generate water at temperatures of more than 360ºF. As this hot water flows up through wells in the ground, it decrease in pressure causing some of the water to boil into steam. The steam is then used to power a generator, and any leftover water and condensed steam is returned to the reservoir. Lastly, binary production specifically uses a second working fluid, with a much lower boiling point than water. The binary fluid is operated through a conventional Rankine cycle.
A calorie is the amount of energy it takes to raise the temperature of 1 kilogram of water 1 degree on a celsius thermometer
A joule is defined as the amount of energy expended by a force of 1 newton moving an object 1 meter in the same direction as the force
A watt is equivalent to one joule per second, corresponding to the power in an electric circuit in which the potential difference is one volt and the current, one ampere
A BTU is the amount of energy needed to heat one pound of water one degree Fahrenheit, measured at its heaviest point.
A kWh is the amount of power consumed or generated over a period of one hour.
Horsepower is a unit of power equal to 550 foot-pounds per second (745.7 watts).
Laws of Thermodynamics
- The first law is "conservation of matter and energy," which states that matter and energy cannot be created or destroyed. Matter can be changed from one for to another, like water to ice, and energy can be stored or placed into motion, such as potential and kinetic energy. However, the main concept is that in the end the same amount of energy or matter has to be equivalent to that from which it started. For example when a roller coaster is at the peak of the top, an resting before its decent the energy is considered to be stored, or potential. As soon as it begin its decent down hill however the energy is changed into kinetic energy, which makes the roller coaster move.
- The second law of thermodynamics states that energy of all sorts, whether it be mechanical, chemical, nuclear, thermal, etc. tends to change itself spontaneously into a more scattered, irregular, or less organized, form. This law is sometimes stated as "entropy increases"; entropy being random, unavailable energy. To illustrate, a athlete eats food that is nutritious before she goes out to run a race. The athlete is then converting the concentrated food through the process if mechanically moving her muscles, to kinetic energy by pushing her self forward towards he finish line, and then release it through thermal energy by building up a good sweat. Thus completing the series of how energy flows from being benefical to non-useful.
