Why Does Electricity Cost Money and How Can You Save Money?

# data[].attributes.body
Electricity costs consumers money because companies need to make their money back from the cost of their facility and fuel. Most companies charge their customers on the number of kilowatt-hours (power consumption of 1,000 watts for 1 hour) of energy they use. You can save money on electricity by turning off the lights and other appliances, if your water heater is powered by electricity, take shorter colder showers, and putting the temperature on your thermostat down.

Thermal Power is produced when a fuel source is burned to create heat, which then produces steam to spin turbines. Thermal energy is the main producer of electricity, with around 75%% of electricity coming from coal, oil, and natural gas.

Hydroelectric power is water power. It is either powered by a river or waterfall which spins a turbine, and powers a generator.

1: Coal. This is the most common energy source to create electricity. All it is is coal being burned to heat water, which produces steam that pushes a large turbine to generate electricity.
2: Hydro power. Hydro power is power from falling or running water that spins one or more turbines to produce electricity.
3: Solar power. Solar power works by capturing sunlight from large solar panels which can either be transferred through various technology to power steam turbines(large scale usage), or to directly push electrons out of their shell(Smaller scale usage).

Why Isn't Electricity Renewable or Nonrenewable?

# data[].attributes.body
Electricity isn't considered renewable or nonrenewable because to create electricity, you need mechanical energy to be transferred into electricity, and you can produce mechanical energy with sources such as water, wind, or the sun, which are renewable, or resources such as natural gas, coal, and oil, which are not renewable.

Geothermal power is thermal energy from the earth, which is then either used or stored. It is created using steam produced by heat emanating from the molten core of the earth.

The interaction of electric currents or fields and magnetic fields. Every time a magnetic field is changed, an electrical field is created, and vice versa

Batteries relate to our chemistry unit because of chemical reactions and different solutions and metals. A battery produces electricity using two different metals in a chemical solution. A chemical reaction then pushes more electrons out of their shell and towards the load.

The electric potential energy per unit charge

A magnetic field can move electrons. Copper and some other metals have loosely held electrons, which are easily pushed by the magnet from the wire to the load.

# data[].attributes.body
The molecules in a magnet are arranged to create a magnetic field around the magnet. That type of field will attract if there is a N and S side. If two N or two S are put together, they will repel each other.

How is electricity related to our study of atoms? 

# data[].attributes.body
The study of atoms includes studying electrons which are a part of the atom. Electricity is simply moving electrons.

A series circuit is a circuit where each load (Component that consumes energy) is connected to the same energy source by the same wire. The same current flows through each component, and the voltage of the circuit is the sum of the voltages across each component.  In a series circuit, the total resistance is equal to the sum of all resistances, and the same current passes through each resistor(load).

Claim: Hydro Power is the best renewable energy source.

Evidence: Hydro power converts 90% of available power. That is WAY more than any source, renewable or not. Hydro power doesn't use any fossil fuels or chemicals so the water isn't harmed.In the US, the average cost of hydro power is around 85 cents, making it a very cheap energy source, and you only need to buy turbines once or maybe twice, since manufacturers quote the life of a turbine 25+ years.

Reasoning: Hydro power is fueled by water,which is a completely free and renewable resource. It causes no pollution at all while creating electricity for us.
Also, you can do it wherever there is running water, so there's a ton of places to do it. Since hydroelectric power goes straight to the grid, it can even be used as a backup in case of a power outage if needed. Hydro power is on of the cheapest energy sources and can easily last more than 25 years, some closer to 50 years! Since you only need to buy a turbine once, there aren't any monthly bills, except for the occasional maintenance of the turbines. The dams can also create reservoirs which are great for water sports and recreation.

A circuit is a completed loop of wire with a load, source, and a current. You turn electricity on and off by opening and closing the circuit.
A series circuit is a circuit where each load (Component that consumes energy) is connected to the same energy source by the same wire. The same current flows through each component, and the voltage of the circuit is the sum of the voltages across each component.  In a series circuit, the total resistance is equal to the sum of all resistances, and the same current passes through each resistor(load), so if one component goes out the rest won't work.
In a parallel circuit, each load is connected by a different wire to the same source, so each load shares the same current, and the voltage is still the same through all components, but there are multiple ways for the current to travel, so if one path is broken, the others will still work.

Transformers are located along power lines to either increase voltage or decrease voltage to make it efficient and safe

# data[].attributes.body
1)Power plant creates electricity
2)A "transformer" steps up the voltage so that not much electricity is lost in the transition to the transmission line
3)Transmission lines transports electricity
4)Voltage is stepped down by another transformer
5)Distribution lines distribute electricity to the places that need it
6)EFFECT
You get electricity at home or places that it is neccesary

This system model shows how electricity from a generator gets to its customers.

# data[].attributes.body
1: Wind blows into turbine
2:Blades start rotating and spins main turbine shaft
3:Main turbine shaft transfers mechanical energy towards the generator
4:The gearbox increases rotational speeds and transfers energy to the high speed turbine shaft.
5:The high speed turbine shaft powers the generator with its high rotating speeds.
6:The turbine generator is what converts the mechanical energy to electrical energy by using the rotating force transferred from the gears and turbine shaft.
