Denmark produced one third of its electricity from the wind in 2013. In no other country has wind’s share of annual electricity generation yet topped 30 percent. But the Danes are not stopping there—they are eyeing a goal of 50 percent wind by 2020, with most of the needed expansion coming from offshore wind farms.

In a breakthrough, scientists have developed a new low cost, efficient and environment-friendly solar cell that uses tin instead of the hazardous lead.

Researchers from Northwestern University are among the first to create a solar cell that uses a structure called perovskite, with tin as the light-absorbing material instead of lead.

"Exculding the use of lead is a quantum leap in the process of creating a very promising type of solar cell called a perovskite," said Mercouri G Kanatzidis, an inorganic chemist with expertise in dealing with tin.
