Mr. Warren wanted his family to play a role in _______ the planet, so he read a lot about the electrical system. Then, he _______ to create electricity to power everything they needed for their daily lives.

The kids were _______ at first. “Will we still be able to watch TV? What about the computer?” they asked. “Don’t worry at all,” said their father. “Just because we are going to create our own electricity doesn’t mean we have to live in the _______.”

“We are going to set up a wind generator (发电机),” explained Mrs. Warren. “Wind is a great way to _______ electricity. It’s not only free but also clean. The wind doesn’t blow all the time, though. That’s _______ we need to store (储存) our power. Then, when there is no wind, we will still have power to run everything in our house.”

Mr. Warren added, “We are also going to collect _______ from the sun and turn it into electricity. So, when the wind blows, we have power. When the _______ shines, we have power, too.”
