These new developments came quickly. `Ten years ago, it took a lot of money to the call the other side of the world. What was once unthinkable is now free using Skype,' said Ridder.
Energy over twenty years virtually free
Energy prices may rise each year, but over twenty years we will pay almost nothing for energy. This is one of the predictions of Professor Willem de Ridder in his latest book Symbiosis. He thinks enough energy can come from the Sun. De Ridder knows all the skeptical stories around solar energy, but according to many new developments, he forecast a bright future. `It is now one of the fastest growing sources of energy,' said De Ridder in an interview with KAS magazine. He also compares it to the development of the telephone and internet.
