Photovoltaic power plant near Almeria in South Spain. The photovoltaic cells convert sunlight into electricity.
The sun provides us with enough energy every hour to provide the world's energy needs for a year. The challenges are how to capture it cheaply and then develop ways of storing the electricity. Without storage, we can't have electricity when the sun's not shining which isn't much use on a cold, dark night. One answer is to combine solar with other technologies, making it one of a mix of possible solutions.
