It accumulates energy when there's light, and it accumulates energy when there's wind, just waiting for you to turn on the switch.

It accumulates energy when there's light, and it accumulates energy when there's wind, just waiting for you to turn on the switch.

You don't usually pay much attention to the windmill and the row of boards in the yard. When the light is good, the boards are drying; when the wind is strong, the windmill is turning. You go about your work, busy as you are, as if they don't exist. But they're always working—not for you to see, but for you to accumulate.

When there's light, it accumulates the sun's energy little by little, turning it into electricity and storing it in the battery. When there's wind, it accumulates the wind's energy little by little, also turning it into electricity and storing it in the same place. When you're not home, it's accumulating; when you're sleeping, it's still accumulating. Accumulating until it's full, accumulating to its fullest.

You don't know how much it's accumulated, you only know that whenever you need it, it's there. When you come home at night, you turn on the switch, and the light comes on; when you get up in the middle of the night, you press a button, and the fan starts; when you cook in the morning, you plug in the rice cooker, and the rice is cooked. Where does all that electricity come from? Is it accumulated during the day or at night? You may not know, and it won't say, but it's there anyway.

The best part is, it never waits for you to ask. When you want to use it, it's there; when you don't want to use it, it keeps accumulating. It doesn't bother you, doesn't boast, and doesn't complain. Like a most attentive butler, it prepares everything you need little by little, just waiting for you to turn on the switch.

It accumulates electricity when there's light, and it accumulates electricity when there's wind, all waiting for you to turn on the switch. From today onwards, your electricity isn't just available on demand; it's always available. You just turn on the switch, and leave the rest to it.
