Mr. Warren wanted his family to play a role
in4the

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
