Energy Future in Perspective

Businessweek has a good run down of energy alternatives:

HYDROGEN FOR POWER
PROS A clean substitute for gasoline and other fuels
CONS Consumes more energy to make than it yields

NEW ATOMIC REACTORS
PROS A safer, more efficient design, plus no greenhouse-gas emissions
CONS Many still hate nukes, and there's a waste-storage problem

METHANE HYDRATE
PROS A super-abundant source of clean-burning natural gas
CONS Sea floor deposits cannot be tapped using conventional wells

LIQUEFIED NATURAL GAS TERMINALS
PROS Lets the U.S. and others import big amounts of cheap natural gas
CONS Facilities are costly. Neighbors fear explosions

SOLAR POWER
PROS Renewable and non-polluting source of electricity
CONS Still more expensive than fossil fuels; needs a sunny setting
