Virginia, with its extensive coal resources and four commercial nuclear reactors (two each at North Anna and at Surry), is still a net importer of energy. Virginia imports about half of the energy it uses, but that's not the same as importing half of its electricity needs. Most of the imported energy is petroleum used for transportation, plus natural gas used for heating and manufacturing.
Virginia exports coal through the CSX terminal at Newport News and the Norfolk Southern terminal at Lamberts Point in Norfolk. Virginia also imports some coal for its power plants, including nearby West Virginia coal and also low-sulfur coal from further away that reduces air quality problems.
Statistics about energy are hard to comprehend and may not appear to be consistent if you confuse "energy" with "electricity," but you can still use the numbers to see the patterns and get the "big picture." According to the Energy Information Administration:1
According to the Virginia Energy Overview,2 from the Virginia Center for Coal and Energy Research:
Oil production in the state is very limited - there are just two tiny oil fields (Ben Hur and Rose Hill) in Lee County, plus liquids from natural gas production in the Roaring Fork field in Wise County. Oil production is too small to justify a wide network of wells with pipelines connecting them. Instead, oil is pumped from underground, stored in metal tanks at each well, and collected by trucks that drive to each well.
Virginia also produces some natural gas, including methane (CH4) from coal seams that are too thin/too deep to mine for the coal. "Virginia's natural gas production has increased dramatically in recent years, from less than 20 million cubic feet in 1970 to more than 85 million cubic feet in 2004. Most of this increase has occurred due to expansion of coalbed methane production in Buchanan and Dickenson counties."3 Though coalbed methane production will increase in the Appalachian Plateau, Virginia will always be a net importer of oil and gas - as long as cars and trucks use an internal combustion engine powered by gasoline/diesel.
Virginia is also a net importer of electricity, even though that fuel is rarely used in the transportation sector. Electricity is produced in only a handful of locations in Virginia, but a complex distribution system of power lines built in the last 80 years carries it to virtually every house in the state. Virginia is building new power plants to handle the increasing demand, both from increased use per capita (your computer requires it...) and because Virginia's population is steadily increasing.
In Virginia, the State Corporation Commission has regulated electrical utilities since 1914.4 With deregulation of utilities, customers are getting to choose their energy supplier and starting to ask basic questions about the industry. A cursory review will show that both physics and government regulations shaped where power plants and power lines were built in Virginia. If you look at Virginia as an economic geographer, you will discover patterns of human activity and resource allocation that can be mapped or related to locations. The geography of electricity - the primary form of energy used in the state, other than for automobiles - stimulates such questions as:
Some industrial plants and large organizations co-generate steam and electricity at their facilities. Virginia Tech has used its coal-fired power plant to supply power for both the campus and local customers since 1890. A few waste-to-energy incinerators burn garbage and create electricity at the same time, such as the facility in southern Fairfax County at Lorton.
There are even a few back-to-the-earthers living in Floyd County and other rural locations in Virginia (plus off-the-grid owners of some very expensive homes in Loudoun County) who generate their own electricity through solar power or small Pelton wheels in the creeks. However, most Virginians rely upon the grid of power lines to deliver electricity generated somewhere else to their house or business.
