Congress may extend daylight-saving time

Sweet !

But why?
says:

"The more daylight we have, the less electricity we use,' said [Rep. Ed Markey], who cited Transportation Department estimates that showed the two-month extension would save the equivalent of 10,000 barrels of oil a day.

10,000 of some things is a lot. Is is a lot of oil ?

The country uses about 20 million barrels of oil a day.

Hmm.
