Renewable Energy
As the global economy moves beyond oil, the strategic importance of the world’s most critical hydrocarbon chokepoint is likely to decline rapidly.
Data centers consume enormous amounts of power, but their steady demand could make the grid more efficient — and lower costs for everyone.
A new generation of self-healing tools could make the U.S.'s aging power grid far more resilient against modern threats.
A firsthand look at China’s material progress and clean-tech revolution -- and what could happen if we let an authoritarian state steer AI's future.
The idea that it’s “too late” to reduce emissions fuels cynicism and despair, putting us on an even worse trajectory.
There are plenty of engineering obstacles, and those can be overcome. But you cannot change the laws of physics, and those matter too.
New biotech tools could clean up everything from construction to agriculture.
The case that a bipartisan movement structured around progress and reform may be reaching critical mass.
Barriers to energy abundance — and how to overcome them — were front and center at Progress Conference 2025.
Solar power has the disadvantage that there's no Sun at night. Satellite startup Reflect Orbital wants to change that, but at what cost?
Nuclear chemist Tim Gregory joins Big Think to make the case that nuclear energy can still transform the world for the better.
One of the most original and optimistic thinkers in America sketches some big ideas about what's possible with AI in the next 25 years.
Tech expert Peter Leyden argues that we have a historic opportunity to harness AI and other transformative technologies in order to make a much better world over the next 25 years.
We've wasted our time and resources ideologically policing and punishing each other for far too long. Here's a better route to prosperity.
Retrofitting America's aging dams for hydropower — while removing ecologically harmful ones — may be a productive path forward.
And can we run the grid of the future without AI?
