Earth Day E-Book Examines The Future of Energy: Earth, Wind and Fire

Scientific American E-Book: The Future of Energy: Earth, Wind and Fire

Since the Industrial Revolution our civilization has depended on fossil fuels to generate energy—first it was coal; then petroleum. But there are two problems: the first is that petroleum isn’t an infinite resource; and the second is that burning coal and oil puts billions of tons of carbon dioxide into the atmosphere, trapping heat. Temperatures [...]

Imagine if the world’s two largest polluters unilaterally decide to cut emissions of carbon dioxide, the ubiquitous gas responsible for the bulk of global warming. At the same time, a major developing country admits that future growth will have to be balanced with CO2 pollution limits. Meanwhile, an industrialized nation country takes responsibility for the [...]

An air-conditioned cabin is the best way to drop a car’s fuel efficiency on a hot day. This is true of electric vehicles (EV) as much as it is for gas-guzzlers. Researchers in Singapore, who know something about hot-weather driving, say they’ve found a way to help an EV to run up to 20 percent [...]

Solar-Powered Ford Aims to Drive Off-Grid

Ford,solar,CES,auto

Solar-powered cars have been little more than a novelty to date, experimental vehicles resembling photovoltaic-laden surfboards designed mostly for racing across deserts. Expensive batteries, relatively inefficient PV energy conversion and the lack of intense sunlight in many places have made sun-powered passenger vehicles impractical. Ford is looking to change that with a version of its [...]
