How is this type of energy formed?
Biomass gasification is when agricultural, forestry or demolition waste is turned into a gas by cooking the carbon-containing material in a low-oxygen environment.
Are there some local examples of where it is or could be used?

What are the advantages of this type of energy?
Availability- forest residues are VERY easy to find in southeast US. Over 100 thousand tonnes per year are found in some areas there.
Economically- In 2007 alone, the ethanol industry helped create more than 238,000 jobs in all sectors of the economy, boosted U.S. household income by $12.3 billion through increased economic activity and new jobs, and added an estimated $4.6 billion in federal tax revenue and nearly $3.6 billion in state and local tax revenues. Growth of the biomass industry is creating new markets and employment for farmers and foresters, as well as job opportunities in processing and distribution.
Environmentally- less greenhouse gases. Biofuels have the added benefit of providing a "carbon sink." As crops grow to produce the feedstocks for making the biofuel, they absorb carbon dioxide from the atmosphere.
What are the disadvantages of this type of energy?
