M: Thank you. As you can see, little by little, Americans are turning to solar power, tapping the strength of the sun for energy.
W: Yeah, that's true. Sunlight has already been used for heating or cooling homes and office buildings in the sunny south.
M: Experts say all signs point to the birth of the solar energy industry. Right now, an increasing number of companies are selling solar collector panels to heat and cool homes or to heat water. The glass and metal panels each cost from ＄100 to more than ＄500, and the three or four-bedroom home usually requires a dozen or more. They look like sandwiches. They are usually placed in rooftops. Nobody knows how many have been sold, and in addition, many people have built their own units. It has been estimated that solar power equipment will be a $1.3 billion industry by 1995, and more than a million homes will use sunlight for heat, air conditioning or to generate electricity, both in the cities and in countryside.
W: Wow! That is really big business.

W: They must be absolutely mad, more nuclear power stations!
M: OK. Jane. But we've got to get the energy from somewhere, haven't we？ We can't just go on using oil and coal.
W: Look. The main point is they're just net safe. They're a real menace, everyone of these things is an accident waiting to happen. Look at Chernobyl, for goodness' sake!
M: Yes, OK, I agree there's a risk. Of course there is. But it's minimal. With modern technology, nuclear reactors are much safer:
W: Much safer! You must be joking. No. Look at all that radioactive waste they're dumping into the sea and underground. Nobody re ally knows what'll happen long-terms.
M: That is a problem. Sure. But it's also true that nuclear energy is cheap and can produce electricity very quickly. Lots of countries have no alternatives. They don't have any oil, coal or anything. What are they supposed to do？
W: Oh, come on! There're lots of possibilities. Well, quite a few. We just haven't really looked at them seriously enough. There's solar energy, and wind power and, what's called wave power. We've still got a lot of coal.
W: Alright. But they'll all take time and money to develop. We need energy now and nuclear power is the best alternative.
M: Oh, I don't believe this. I reckon it's just crazy.
