In 2008 the average electricity tariff in the U.S. was 9.82 cents/kWh, up from 6.9 cents/kWh in 1995. Residential tariffs were somewhat higher 11.36 cents/kWh, while commercial tariffs stood at 10.28 cents/kWh and industrial tariffs at 7.01 cents/kWh. The cost of supplying high-voltage power to high-volume industrial customers is lower than the cost of providing low-voltage (110 V) power to residential and commercial customers.Key federal legislation related to the electricity sector includes:

Federal PTC expired in 1999 and was not renewed until late in the year, the wind industry to suffer a major downturn in 2000. The PTC also expired in 2002 and 2004, both times causing a major slowing in capacity additions.Biomass electricity generation includes electricity generated using wood and wood waste, municipal solid waste, landfill gases, sludge waste, and other biomass solids, liquids, and gases.

is expressed as a supply curve showing the quantity of a resource available at a specific cost. Methodologies for calculating the economic potential of a renewable resource have variable degrees of complexity by source and include considerations of energy, environmental, economic, existing and new infrastructure, and social factors. When sustainability factors are included, economic potentials can be refined into a “sustainable potential” for a specific region. Sustainability factors can be loca
