You can write it like this:
Sunlight can produce a lot of energy. People began to use the energy from the sunlight in different ways many years ago. We can use it to warm the house in the winter, to heat the water for baths, and to produce electricity. What’s more, we can even use it to run vehicles directly in the near future.
As is known to us, the energy from the sunlight has a lot of advantages. For example, it is clean, renewable and non-polluting. Besides, it does no harm to our nature. So we’d better use it as much as possible.
