REALITY OF THE PROBLEMS MAKES BOOM, BUST UNLIKELY

In his State of the Union speech, President Bush said he wants 20 percent of all gasoline consumption to come from alternative sources in 10 years. Assuming gas prices of $2 a gallon, the value of the alternative fuel market will be more than $60 billion by 2012. That’s a big market to go after, says Vinod Khosla, head of Khosla Ventures, who wants us to declare a “war on oil.” If you consider the $20 billion online advertising market where search giants Google and Yahoo play, you can see that the alternative fuel market alone is huge.
