Alexandros Charalambides: Why aren't we only using solar power?

Solar power is cheaper and more sustainable than our current coal-fueled power plants, so why haven't we made the switch? The real culprits here are the clouds, which make solar power difficult to control. Alexandros George Charalambides explains how solar towers and panels create electricity and how scientists are trying to create a system that...

Fabio Pacucci: Could we harness the power of a black hole?

Imagine a distant future when humans reach beyond Earth, forge cities on planets thousands of light-years away, and maintain a galactic web of trade and transport. What would it take to make that leap? And where would we get enough energy to power that civilization? Fabio Pacucci explores the possibility of harnessing energy from a black hole to...

Netta Schramm: Why don't perpetual motion machines ever work?

Perpetual motion machines — devices that can do work indefinitely without any external energy source — have captured many inventors' imaginations because they could totally transform our relationship with energy. There's just one problem: they don't work. Why not? Netta Schramm describes the pitfalls of perpetual motion machines. [Directed by TE...

Rose M. Mutiso: How to bring affordable, sustainable electricity to Africa

Energy poverty, or the lack of access to electricity and other basic energy services, affects nearly two-thirds of Sub-Saharan Africa. As the region's population continues to increase, so will the need to build a new energy system to grow with it, says Rose M. Mutiso. In a bold talk, she discusses how a balanced mix of solutions like solar, wind...

Juan Enriquez: Using biology to rethink the energy challenge

Juan Enriquez challenges our definition of bioenergy. Oil, coal, gas and other hydrocarbons are not chemical but biological products, based on plant matter -- and thus, growable. Our whole approach to fuel, he argues, needs to change.

Tessa Khan: How can we escape soaring energy bills? Stop using fossil fuels

As oil and gas companies continue to make record profits off of the same forces driving climate chaos, war and soaring energy bills, it's become clear that boom times for the fossil fuel industry are bad times for the rest of us, says climate change lawyer Tessa Khan. She asks us to consider the true cost of our reliance on fossil fuels, outlini...

Lorie Wigle: Weaving a strong smart grid

Integrating disparate national electricity systems into a smart grid allows us to integrate renewable energy, be more efficient and empower consumers to use power wisely. But as we add intelligence to these systems, we introduce a vulnerability into it as well. Lorie Wigle outlines a new project to protect these complex and vital grids from attack.
