- [Narrator] We use electricity every day.
It powers our homes, our work,
our entertainment and more.
But have you ever wondered where it comes from
and how does it show up at the flip of a switch.
Energy companies like Idaho Power
use machines called generators
to convert energy from flowing water, wind, steam,
or gas into an electrical current we can use.
That current is created by using a turbine
to move a magnet inside a coil of copper wire.
At Idaho Power about half of our energy
is produced by hydroelectric projects
on the Snake River.
At a dam,
moving water from the rivers flow
spins hydro electric turbines.
The turbines rotate a generator shaft inside
a coil of copper wiring, creating electricity.
The clean energy produced by hydro-power
is also one of Idaho Power's most cost effective resources,
allowing us to offer some of the lowest energy prices
in the country.
After the energy is generated at a power plant,
it must be moved to your home.
First, it goes through a step up transformer,
which converts it to high voltage electricity.
This energy travels long distances
using high voltage transmission towers and lines.
Then the energy goes through a step down transformer.
Typically at a substation.
Electricity leaves the substation and travels to your house
through overhead or underground distribution lines.
Then when you turn on your lights, your instant pot
or your TV, electricity is there to make it happen.
The most fascinating part,
the process of generating transmitting
and distributing energy happens almost instantaneously.
Electricity is not readily stored,
but it can travel at nearly the speed of light,
which means when you flip the switch,
the energy you're using was generated probably
at an Idaho Power Plant at almost the exact same time.
