...water is the elixir of life, it's no wonder that Earth - which is 70% ocean - simply teems with living things. The other planets and moons in the solar system don't have it so good. They're forbidding places that are hydrological deserts, and thus biological ones...
That, at least, had long been the conventional wisdom, but in recent years, scientists have come to learn that by some measures, the solar system fairly sloshes with water. Mars, we now know, was once as wet as Earth and still harbors ice and perhaps liquid water. The moon is thought to have water locked in permafrost at its poles. Jupiter's moon Europa is probably home to a globe-girdling ocean beneath a thin rind of ice, and its Jovian sisters Callisto and Ganymede appear to be icy and wet too. Now, according to new findings by the Cassini...
...Japan has already sped ahead of the U.S. in hybrid-car technology. China is emerging as a leader in electric cars, solar power and wind power. South Korea is not yet known for anything environmentally friendly, but that is about to change. The South Korean government is spending $31 billion to fund research in 27 green technologies, including non-silicon-based solar cells, biomass fuels and carbon collection, storage and processing.

...Will East Asia win the green race? The Europeans, who are leading the way on carbon-trading, are very much in the game, particularly in recycling and solar and wind power. Japan, China and South Korea also have some delicate issues to settle. One of the most contentious is likely to be intellectual-property protection, which is not particularly strong in China. And the U.S. may still be a contender. Sputnik sparked an extraordinary American effort that culminated in Neil Armstrong's 1969 moon walk, which sealed the U.S.'s supremacy in space. Last month, Washington launched a $25 billion...
...just 20% of U.S. electricity would need to come from renewables by 2020, but that allows for nuclear power, and many utilities would be allowed to escape the requirement altogether. "We're off to a slow start," says Peter Duprey, CEO of Acciona Energy North America, which operates wind, solar and biofuel plants. "I'm disappointed with how things have gone [under Obama...
