Term
Why do we need to be careful when studying projections?
Definition
They are likely to have a bias
Term
What has happened with net imports of energy from 1980 to 2008?
Definition
Imports have increased
Term
What does EIA project will happen with energy net imports from now until 2035?
Definition
The amount of net imports will stay the same (consumption and production will continue to increase) but since comsumption increased, the PERCENTAGE of net imports is decreasing
Term

Definition
The projection shows that the net imports of energy as a share of total US energy demand are decling.  The growth in energy imports is moderated by the indcreased use of biofuels, reductions in demand, imrpovement in the efficiency of appliances and higher energy prices; the net import share of the total US energy consumption n 2035 is 20% compared to 26% in 2008
