Solar energy holds the best potential for meeting humanity’s future long-term energy needs while cutting greenhouse gas emissions—but to realize this potential will require increased emphasis on developing lower-cost technologies and more effective deployment policy. This lecture presents results of a comprehensive study on The Future of Solar Energy by the MIT Energy Initiative (MITEI), which is part of a series of multidisciplinary reports that examine the role various energy sources could play in meeting future energy demand under carbon dioxide emission constraints.

Everything we see today, our precious atoms and molecules, got here by traveling on swaths of dark matter. From the oscillations of the hot plasma of the primordial universe, to the formation and dynamics of modern galaxies, dark matter plays a necessary role. The very construct in which we sit is defined by its abundance. Our universe’s evolution is controlled tightly by a cosmic tug-of-war between dark matter and dark energy.

The Rupununi region of Guyana is a mix of lowland savannas and tropical forests. The vast savannas include an expansive network of wetlands that connect the Guyana’s main river drainage, Essequibo River, to the Amazon River during the rainy season. This unique biogeographic feature influences fish communities of the area. One of the fish species found here is in dire need of protection.

There’s a treasure at the edge of the Solar System. It’s a data recorder, aboard the New Horizons spacecraft, slowly sending to Earth several gigabytes acquired during last summer’s flyby of Pluto.  That information is still coming down.  At the mission’s home base in Maryland, William S. Higgins witnessed the excitement during the encounter.  Now he reviews results, downlinked in recent months, that are illuminating the mysteries of Pluto, its five moons, and its neighborhood.

Global warming is a reality that we will be forced to adapt to in the coming decades. A true solution will not come from one area; there is no silver bullet. Rather, lasting and significant change will come from a suite of modifications to our behavior, as well as technological improvements.
