There is not enough oil in the world now. As time goes by,it becomes less and less. So what are we going to do when oil runs out? Perhaps we will go back to use our horses,carriages (馬車) and bicycles.
In the Second World War,some people didn’t use gas made from petroleum (石油) in their cars. They made gas from wood and plants instead. The car didnJt go fast,but they ran,so this was better than nothing. However,in the future,we can’t c?t down all our trees to make gas,we need our trees for other things too.
Besides different types of gas,we can also use electricity (電) to run our cars,but first we must make electricity!Some countries have coal and make electricity with that,but we might not always have coal,either. Other countries have big,strong rivers,and they can use the power of water to turn turbines (滿輪機) and make electricity easily and cheaply.
We are also able to get power from the ocean tides (海潮). We put turbines into the mouth of the river. When the tide comes in,the water turns the turbines and when it goes out,it turns them again.
