POWER TRIP
The industrialized world has a mind-boggling appetite for energy. That demand is exploding now that countries such as India and China are rapidly modernizing. Where will all the energy that the world needs come from in the decades ahead? That’s a question that it may take the rest of this century to answer. Current Science’s special digital issue, “Power Trip: Part Two,” highlights some of the possible answers. They include promising new sources of power as well as innovative ways of making energy consumption more efficient. To access the digital issue, click on the Themed Web Sites link at right. There you’ll also find “Power Trip: Part One,” originally published in 2011. It explains what energy is, where it comes from and where it goes, and why the world needs so much of it.
