Answer: Lights run on electricity. If you leave lights on when you’re not using them, you waste electricity. Turning off lights when you leave a room not only saves electricity, it also helps reduce your family’s energy bill.

Answer: Electricity is measured in voltage (abbreviated as volts) and amperage (abbreviated as amps). To understand the difference between them, think of water in a hose. Opening the hose faucet supplies the pressure to move the water, and this pressure is like voltage. The amount of water that moves through the hose is like amperage. There is a third unit of measurement, wattage (abbreviated as watts) that describes the work electricity does. Watts are the product of volts and amps. Or, to say it mathematically, watts = volts x amps.
Answer: The energy cycle is a process by which some of the sun’s energy is cycled through plants and then released back into the environment. The cycle starts with photosynthesis, in which plants capture sunlight to produce sugars. The sugars are used by plants as food to give them energy to grow. Because animals can’t produce their own food the way plants can, they get their energy by consuming plants, or animals that have eaten plants. When the animals die, they decompose and the energy that is stored in their bodies is released back into the environment, completing the cycle.
Answer: PG&E provides both natural gas and electricity to our customers (hence our name, Pacific Gas & Electric). We serve approximately 15 million people throughout a 70,000-square-mile service area in northern and central California.
Answer: Turbines turn electromagnets that are surrounded by heavy coils of copper wire. The moving magnets cause the electrons in the copper wire to move from atom to atom, generating electricity.
Answer: Electricity starts with atoms, the tiny particles that make up everything around us. Even tinier particles called electrons orbit the centers of atoms. When electrons move between atoms through a wire, electricity results. Electricity is typically produced at power plants, where various energy sources are used to turn turbines. The turbines turn electromagnets that are surrounded by heavy coils of copper wire. The moving magnets cause the electrons in the copper wire to move from atom to atom, generating electricity.
