A city in California has got some new buses. They cost $490,000 each. The new buses are different from the old ones. These new buses are better for the environment. They are called hybrid (混合动力的) buses. They run on diesel (柴油的) and electric power. This will help keep the air cleaner.

The man drove the new bus on Wednesday and noticed a difference right away. “I get to have clean air for a change”, said driver Melvin Day. “I’m smelling diesel all day long when I drive the old ones.”

The company that builds the buses had many good things to say about them. For example, they said they use a lot less fuel (燃料). They also said that they are 90% cleaner for the environment. The buses are very quiet, too.

The buses have a diesel engine in the back and batteries (电池) on top. When the engine starts up, it is powered by electricity. Then the diesel power takes over.

Over time the city would like to use the new hybrid buses instead of all 50 of their buses. They hope to do this over the next three years. The city will give money to help buy the new kind of buses.

One other bit of good news: the price of the bus ticket will not rise because of the new buses.
