For the past few weeks,we have been discussing national energy conservation alternatives for the future.Today I’m going to talk about what one community’s presently doing to conserve energy.The people of Davis,California have succeeded in cutting their energy consumption by 1/3 since 1973.(1)_______________________.All new houses in Davis must have the proper insulation so that heat will not escape unnecessarily during the winter.New houses must also face north or south,so that they will not be overheated by the sun in summer.The law has had a definitely effect.(2)_______________________.There are other energy saving features about Davis.Buses, partially supported by the city,universally transport students throughout the area.There are 24 miles of bicycles paths,and today there are twice as many bicycles as cars in the city.By reducing the available parking space,the city council has succeeded in reducing the number of cars in the city every day.Another benefit of the reduced parking is the greater number of small cars.(3)_______________________.Davis, California has become an energy saving model for other cities.Time is up for today.Next week, we’ll return to our regular topic of national energy alternatives.
