2. Electric current
Electric current, any movement of electric charge carriers,
such as subatomic charged particles (e.g., electrons having
negative charge, protons having positive charge), ions
(atoms that have lost or gained one or more electrons), or
holes (electron deficiencies that may be thought of as
positive particles). Electric current in a wire, where the
charge carriers are electrons, is a measure of the quantity
of charge passing any point of the wire per unit of time. In
alternating current, the motion of the electric charges is
periodically reversed; in direct current it is not. In many
contexts the direction of the current in electric circuits is
taken as the direction of positive charge flow, the direction
opposite to the actual electron drift. When so defined the
current is called conventional current.

sources

● Natural Gas: Natural gas combustion alone, or as part of a
furnace/boiler system, propels turbines to create energy.
● Coal: Most power plants use coal-fired steam turbines to
generate power, though a few convert coal to a gas before using
it in turbines.
● Petroleum: Petroleum can also be burned to produce
combustion gases or steam to power turbines.
● Nuclear Power: With nuclear power, nuclear fission produces
the energy-generating steam necessary to spin turbines and
generate electricity.
● Hydropower: Hydropower from dams and other setups power
turbines via flowing water.
● Wind: Like giant pinwheels, turbines capture energy from the
wind for conversion into electricity.
● Biomass: Derived from plant and animal waste, materials are
burned directly and used as other fuels to power turbines or
internal combustion generators.
● Solar: Energy from the sun is captured in photovoltaic solar
cells, heating fluids to produce steam and drive turbines.
● Geothermal: Heat from within the earth is harnessed to for
heating water into steam to power turbines.

generation

Boil water to produce steam.
Produce heat, and heat fossil, hydroelectric power and
nuclear energy.
Then Turn a turbine to rotate a coil in a magnetic field to
generate electricity.
And Then Use transformers voltage transmission to raise
voltage for distribution.
5. Electricity generated at the power
plant reaches our homes through
multiple substations, transmission and
distribution lines, and transformers.
Newly generated electricity is
transmitted at extremely high voltages
ranging from 275,000 to 500,000
volts in order to reduce transmission
losses. However, to use electricity in
our daily life, this voltage must be
reduced to the appropriate level.

6. Cost and
Commercialization
• The cost of electricity consumption is based on the number
of kilowatt-hours (kWh) of electrical energy used. The
kilowatt-hours are sometimes known as the domestic units of
electricity
• Commercialization: Renewable energy commercialization
involves the deployment of three generations of renewable
energy technologies dating back more than 100 years. First-
generation technologies, which are already mature and
economically competitive, include biomass, hydroelectricity,
geothermal power and heat.
• In Panamanian households: The price is 0.154 USD per kWh.
The average price in the world is 0.135 USD per kWh.

7. Conclusion
The electricity is an essential part of the modern
life and a important part of our economy,
People use the electricity in a lot of things.
Electricity has been a part of our every day
life for a long time now and how it chnaged
us and because of that we have come to the
conclusion that it without any of it we
woudlnt have de technological advancments
we have till this very day. It also is our source
for many chores, our life activities and
everyday we live we utilize it.
