What are energy reserves?

Energy reserves are like a big piggy bank that stores energy for later use.

Imagine you have a favorite snack, and every time you eat it, you save some pieces in your piggy bank. Later, when you're hungry again, you can take out the saved snacks and enjoy them without needing to find more right away. That’s like how energy reserves work, they store energy so we can use it whenever we need it.

Think of your piggy bank as a special kind of storage. In real life, energy reserves help countries keep the lights on and machines running even when there’s not enough energy coming in right now.

For example, some places use big underground storage to hold extra oil or gas, like having lots of snacks already packed away for rainy days.

When there's a lot of energy around, they save some in their piggy bank. When things get busy and we need more energy, they take out what was saved earlier. It’s like sharing your snack with friends when you have extra, but keeping some for yourself too!
