The consumtion numbers only go back 10 years or less. The excess supply numbers are going up though. That means, along with the current plunge in fuel prices, that demand is down.
I work for a railroad, we buy fuel, and haul oil and chemicals from the petroleum industry. Across the board, crude, chemicals, and finished products are all down, including our fuel prices. We still haven’t come back up to fuel usage levels that we saw before the recession, and railroads burn through a shitload of diesel.
What? Supply going up does not mean demand is going down. Oil demand is not down.
Oil demand is 95 million barrels a day. When do you think it was higher?

Railroads as a small part of the US consumption of fuels. And the US is just a fraction of the world's consumption of fuels. Oil demand is global, not just US railroads as an indication of the whole.
Here is a link to the Oil Market Report going back to 1990.

Show me a year where oil demand was greater than now.
