If a car with solar panels mounted on its roof were left outside on a sunny day for 10 hours, it would generate enough electricity for less than 10 miles of driving.
Tokelau, which consists of three small Pacific atolls administered by New Zealand, gets 93% of its electricity from solar panels, and the other 7% from a sustainable supply of coconuts.
Researchers at MIT have created solar cells that can be printed on fabrics and paper, an enticing possibility for people looking to power their homes economically.
