In the 20th century, low-cost, abundant energy enabled global prosperity and development. Now, as living standards rise and urban populations expand, satisfying the ever-growing demand for energy in a sustainable way has become the world's biggest challenge.
Tony Hayward, the CEO of BP, will discuss the tough policy and investment choices involved in navigating toward a lower-carbon world during remarks at the MITEI Colloquium on Thursday, Oct. 29.
How will the energy mix evolve in transportation and power generation? What technologies are available? What actions can governments take to create the right framework for a sustainable future? Hayward will stimulate an informed policy debate in an area where half-truths and misinformation too often hold the field.
Hayward, a member of the MIT Energy Advisory Board, will speak from 4:15 to 5:30 p.m. in 10-250.
The event is free and open to the public; a reception will follow in the Pappalardo Room, 4-304.
This illustration shows a lead sulfide quantum dot array. Each quantum dot (the colored clusters) is 'passivated' by molecules that bind to its surface. Dots that are made up of unequal amounts of lead and sulfur tend to cause electrons (shown in red) to become highly localized, which can substantially lower the electrical transport of the device.Image: Donghun Kim and Jeffrey C.
