The Warrens are a common family.1, this common family has done something special.
A few years ago, they2their big house in town and moved to the countryside. But that's not the only3thing that they did. They built a house which was powered (给……供电) by the wind and the sun in the country!
Mr. Warren wanted his family to play a role in4the planet, so he read a lot about the electrical system. Then, he5to create electricity to power everything they needed for their daily lives. The kids were6at first. "Will we still be able to watch TV?" asked the daughter, Jane. "What about my computer?" asked James, the son. "Don't worry at all," said7father. "Just because we are going to create our own electricity doesn't mean we have to live in the8."
"We are going to set up a wind generator (发电机) ," explained Mr. Warren. "Wind is a great way to9 electricity. It's not only free but also clean. The wind doesn't blow all the time, though. That's10we need to store (存储) our power. Then, when there is no wind, we will11have power to run everything in our house."
Mr. Warren added, "We are also going to collect12from the sun and turn it into electricity. So, when the wind blows, we have power. When the sun13, we have power, too."
It's easy to see that Mr. Warren really14renewable energy. And all his family hold the same15as him. Now, they are living happily in their self-powered countryside home.
