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.

Technological and market forces have converged to make energy storage one of the most exciting — and potentially game-changing — opportunities for commercial and industrial facility managers, grid operators, homeowners and investors.

Forward-thinking utilities, battery suppliers, power inverter producers, system integrators and public-sector supporters are driving a massive expansion of energy storage solutions aimed at enabling the grid of the future — or even a grid-less future.

Although the energy storage value chain includes hundreds — if not thousands — of players, the following are leading the charge.

BISMARCK, N.D. (AP) — Dr. Lyle Best traveled nearly 200 miles from the heart of North Dakota's oil patch Tuesday to tell state regulators one thing: "Slow down."

The North Dakota Industrial Commission is considering a proposal that would cut back on the state's booming oil production as a means of controlling the amount of natural gas that's being burned off at well sites and wasted as a byproduct of the more valuable substance, oil.

But oil companies are fighting the idea of slowing production, and want regulators to consider self-imposed steps to curb natural gas flaring, such as submitting plans for natural gas gathering before applying for a drilling permit.

. . . more than 54,000 wells were planted in and off this coast — part of the 300,000 wells in the state. They're connected by thousands of miles of pipelines, all vulnerable to leaks.

And leak they do.
