Girl: Cool. But this house is nicer. It has grass growing
on its roof. Look! And the grass on its roof keeps the
house cool.
Mom: Hmm – I’d like a house more than an apartment.
Boy: OK, look at this house – it’s on a wind farm!
Dad: That’s good. It uses wind power. We can save a lot
of electricity and money. It’s a nice cheap house.
Mom: But I prefer this house with solar panels. It’s bigger.
And it uses solar power. We can still save money. And
it’s in the countryside with a big yard.
Girl: But the house with the grass roof is the most
beautiful. And they are all eco-homes. So they all save
energy. Let’s look at the grass roof house.
Dad: Good idea.
