In this world there are many problems. It is believed that renewable energies are not harmful to the environment but this is not true. These energies are less harmful but they still cause problems. For example, we need windmills to transform the air into energy and produce eolic energy, but in order to build these windmills we harm the environment with acoustic pollution and endanger the existence of many animal species. Hydraulic power plants also damage the environment.
