All About Energy

What is it?!?

Energy: The ability to do work

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.

Energy Flow!

Power travels from the power plant to your house through a system called the power distribution grid. From there, electricity is generated, where it first travels through a transformer that "steps up" or increases the voltage to allow it to travel more efficiently over a long distance through large transmission lines carried by steel transmission towers. Then Transmission lines carry ramped-up electricity to distribution substations located throughout our service area. Banks of transformers at more than 100 substations "step down" or decrease the electricity's voltage so it can travel through smaller distribution lines and make its way to specific residential and commercial districts. From transformers, electricity travels into buildings through wires called service drops. The service drops connect to a meter box, which measures the amount of electricity being used by a customer. The drops also connect to all of the wires that run inside a home or building’s walls to outlets and switches.

What's the Difference?!?

Alternating Current & Direct Current: Direct current is commonly associated with batteries, fuel cells and solar cells. With direct current, the positive and negative terminals of a battery are always, positive and negative. Current always flows in the same direction between those two terminals. As for alternating current, a commonly associated power source comes from a power plant. In this process, the direction of the current reverses, or alternates, 60 times per second. to illustrate, the power that is available at a wall socket in the United States is 120-volt, 60-cycle AC power. The two currents however are similar in that they both involve the movement of electrons in a current.

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.

Laws of Thermodynamics

  1. 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.
  2. 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.


A turbine is a machine for producing continuous power in which a wheel or rotor is made to revolve by a fast-moving flow of water, steam, gas, air, or other fluid. It has a series of blades, typically made of steel but sometimes ceramic, that can withstand higher temperatures. The fluid goes in one end, pushing the blades and causing them to spin, then gets released out of the opposite side of the machine. The fluid leaves the engine with less energy than it had going in, this allows for a portion of the difference to be captured by the turbine. This captured energy is used as electricity in which it then gets distributated to powerlines and is taken into urban and rural areas for use.

Geothermal Energy! Read All about it!!

Geothermal energy can be found almost anywhere, from as far away as remote deep wells in Indonesia and as close as the dirt in our backyards. Essentially it is heat from the earth and it can be used as an energy source in many ways, from large and complex power stations to small and relatively simple pumping systems. Geothermal energy in short is heat produced directly from hot water within the earth. Environmental advantages of geothermal energy is its clean waster production (its all natural), its quietness doesn't not disturb the organisms living around it, and it is efficient. However disadvantages are its depletes our natural resources, it can cause lands to subside, and it causes damages to are geothermal areas.
