When the wind blows, it stores electricity; when the sun shines, it stores electricity—the house has never lost power.

When the wind blows, it stores electricity; when the sun shines, it stores electricity—the house has never lost power.

When the wind blows, you're busy inside, too busy to look at it. The windmill whirrs in the yard, its blades circling, collecting the wind's energy, converting it into electricity, and storing it in the battery. You don't know how fast it spins, how much it stores, you only know it's there, always turning.

When the sun shines, you're working in the fields, too busy to pay attention to it. The row of boards basking in the sun collects the sunlight, converting it into electricity, storing it in the same place. You don't know how hot the boards are, how much it generates, you only know it's there, always basking.

When the wind blows, it stores electricity; when the sun shines, it stores it electricity. It stores more when the wind is strong, and more when the sunlight is bright. Sometimes the wind blows and the sunlight comes in bursts, but it catches them all, storing them all for you. You don't ask, it doesn't say, it just silently stores, filling it to the brim, storing it completely.

When it gets dark and you get home, you turn on the light switch, and the light comes on. Only then do you realize it hasn't stopped working all day. On windless and dark days, you open the refrigerator, and it's still running; you turn on the TV, and it's still supplying power. Only then do you realize it has stored enough for you to use for a long time.

It was storing power when the wind was blowing, and it was storing power when the sun was shining; the power in your house has never been interrupted. From today onwards, your electricity is not just available on demand, but always available.
