What is electricity?
The energy of flowing electrons.
How is electricity produced?
The most common way to produce electricity and involves moving an electrical conductor in a magnetic field.
Renewable energy
Energy sources that are replaced by natural processes at a rate comparable to their use.
Non-renewable energy
Energy sources that are limited and can eventually run out. Cannot be replaced on a time span of human significance.
Fossil fuels
(Coal) (oil) (natural gas)
Energy sources form from remains of dead plants and animals that were buried millions of years ago.
