What does the man say we can do to deal with oil crisis?

W: How do you feel about oil crisis?
M: It’s frightening. Maybe there will be wars about oil. We need to find alternative energy sources very soon. Any alternatives do you know?
W: I think wind energy and wave energy would play important parts in our lives in the future.

W: Excuse me, I want to buy a new car and I’d like some information about the loans. What are the current interest rates on short-term loans?

W: If I have a loan for ￡ 5 ,000 payable over three years, what will the rate be and how much will the monthly repayments be?
M: OK, I’ll figure it out.
