The Hubbert Curve representing global oil production predicts that?

• oil production will increase exponentially for the foreseeable future.

• oil production will increase, decrease then increase again.

• oil production will reach a peak and then decrease

• oil production will remain constant

Utility companies can best reduce peak demand events by...

• building power plants with larger generating capacity

• keeping an ample supply of coal on hand

• using renewable sources to generate peak electricity needs

• allowing customers to pay lower prices for energy when peak demand is low

Put the items below in correct sequence for using wind to generate electricity.

1- A generator converts mechanical energy into electrical energy.

2- Wind turns the wind turbine blade.

3- A gear box transfers mechanical energy to a generator.

4- Electricity is transferred to the grid.

Why is petroleum the primary fuel used for transportation in the United States?

1. It has a high energy value per unit volume
2. It has quick start and stop times for providing energy
3. It produces a low amount of pollution per Joule

In the use of coal to produce energy, which does NOT decrease the energy efficiency of the process?

• Extracting the coal from the ground

• waste heat

• Cogeneration

• The removal of the waste products

The order of grades of coal from lowest energy content to highest energy content is

An energy-efficient building might include all of the following except

• building materials with low thermal mass.

• a green roof.

• southern exposure with large double-paned windows.

• reused or recycled construction materials.

• photovoltaic solar cells as a source of electricity.
