2. Population Growth Texas California 1960Thousands of people 2003 Thousands of people New York Ohio Some states, such as Texas, California, and Florida saw a tremendous growth in population since the 1960’s. This is one of the factors driving an increase in fuel usage. Many state have not seen very much growth since the 60’s. The majority of population growth has been in the South and the West.

3. Residential 19602003 BBtu MBtu/Person BBtu MBtu/Person 19602003 In 1960, the northern states used slightly more energy per capita than the southern states in the residential sector. By 2003, the states had approximately the same energy use per person. (With the exception of California) FloridaCalifornia

4. Commercial 19602003 BBtu MBtu/Person BBtu MBtu/Person 19602003 In 1960, the commercial energy use per person was relatively small. Only looking at total energy, the powerhouse states like NY and CA were using the most power. By 2003, the entire east coast has exploded in commercial energy use. However, on a per person basis, most of the states are on the same level. Virginia Wyoming

5. Industrial 19602003 BBtu MBtu/Person BBtu MBtu/Person 19602003 In 1960, the Industrial sector was one of the largest consumer of energy. The states that have large supplies of coal and natural gas top the charts here. On 2003, the same story is true. Wyoming, Texas, Louisiana and North Dakota are the largest consumers of energy per capita. Wyoming Texas

6. Transportation 19602003 BBtu MBtu/Person BBtu MBtu/Person 19602003 In 1960, the transportation industry energy use was similar across the country. In 2003, the energy use was still relatively close between most states, with the exception of Wyoming. Louisiana Wyoming

7. Electrical Utilities 19602003 BBtu MBtu/Person BBtu MBtu/Person 19602003 In 1960, the electrical utilities in most states were the same, but some on the west coast and in the Ohio river valley were slightly higher. By 2003, the electrical utilities in states such as Wyoming, West Virginia, and North Dakota have shown steep increases in fuel consumption. This may be due to the large supply of coal in these locations. West Virginia Wyoming

8. Summary Residential – All states saw slight growth in residential fuel consumption. Commercial – All states saw moderate growth in commercial fuel consumption. Industrial – Most states saw substantial growth, with states such as Texas, Wyoming, and North Dakota using the most energy per capita. Transportation – Most states saw moderate increase in fuel consumption, with some states such as Wyoming and Louisiana seeing larger growth rates. Electrical Utilities – This area saw the most dramatic and largest increase in fuel usage per capita. The growth rate across all states was large, but states such as Wyoming, North Dakota, and West Virginia saw as much as a 900% increase.
