Energy goes through high voltage lines, that are installed on towers and before that electricity arrive to your home, a substation transformer reduced the power to lover voltages.

7. What do "greenhouse effect" and "acid rain" mean? How are they related to energy production?

⇨Greenhouse effect: When we burn fossil fuels, gases are released into the air. These gases contribute to the greenhouse effect, wich increases the Earth's average temperature.

⇨Acid rain: Power stations that burn fossil fuels also release other pollution into the air. These pollutants combine with water vapour in the air to produce acid rain.
