The mostly seen things in our campus are the electric bicycles. This situation indicates the rise in a fresh industry---the renewable energy. Although it is just in a developing period, it has already generated a bunch of new technologies, which guarantee the safety of e-bikes. However, the renewable energy doesn’t necessarily mean e-bikes. E-cars, solar power and other forms of new energy are also prosperous. Even if danger still exists, we cannot quit the hope of renewable energy.
