Hi there!
Here you are a new link which will take you to a section of BBC focused on renewable energy.
On this site you will find a number of articles dealing with solar energy, wind farms, batteries, tidal power and many more forms of using natural sources of energy in order not to harm our beloved environment.
You know I have used some articles similar to these ones for the exam on the previous unit of tourism, so If I were you, I would spend some time reading them.
I hope you like them!
