Take a look at these two quotes, both regarding the amount of energy stored in a laptop battery pack. The first is from a New York Times article about solar-thermal-energy generation:rn"The idea is to capture the sun's heat. Heat, unlike electric current, is something that the industry knows how to store cost-effectively. For example, a coffee thermos and a laptop computer's battery store about the same amount of energy, said John S O'Donnell, executive vice president of a company in the solar-thermal business, Ausra The thermos costs about $5, and the laptop battery costs $150, he said, and 'that's why solar thermal is going to be the dominant form.'"
