written by Chiara Crognoletti

We already know the benefits of existing renewable sources of energy. However, most of them still need improving: sun is not always available during the day or in particular regions, hydroelectric power plants may destroy the surrounding areas, wind turbines are quite huge and noisy.

Most of them need more research and are not in place yet, but they provide some possibilities to encourage efforts, in order to satisfy the growing energy demand with less pollution and in a more sustainable way for the world and us all.
