I've had the pleasure to visit the beautiful island of Tenerife a few times, which is the largest of the Canary Islands. Being a very mountainous island, it's a difficult place to build a railway system, but they're catching up with a new tramway line which serves the island's capital, Santa Cruz de Tenerife and the nearby town of La Laguna. The company that is building it just got the permission to install a very large array of photovoltaic panels to produce electricity directly from sunlight, so that most of the energy needs of this tramway will come from the sun. The 600 kW system is expected to have a lifespan of 20 years.
