What is electricity?
Electricity is the energy that powers lights, appliances, heat pumps, EV chargers, computers, and other devices in homes and businesses.
Where does electricity come from?
Electricity is produced by wind farms, solar panels, hydro plants, biomass plants, gas plants, coal plants, and imports from connected countries.
How does electricity reach my home?
Electricity moves through high-voltage transmission lines, then into local distribution networks, and finally through the connection to your home or business.
Can electricity be stored?
Yes, but only in limited amounts with batteries and other storage systems. Most electricity is used very close to the time it is produced.
