Biomass

One of the largest sources of energy alternatives in Kentucky may be biomass, which refers to formerly live mass that can be burned to create electricity. While Biomass can be defined as "renewable", it is not without controversy. According to US Energy Information Administration (EIA) resources, Biomass could include agricultural residues, animal manure, wood wastes, food and paper industry residues, municipal green wastes, sewage sludge, and a large variety of grasses and crops. (There are at least 14 native Kentucky plant species considered to be suitable for biomass energy production). So depending on the fuel source and production process, the environmental impact of Biomass can vary significantly.  

Biomass energy can be designed for small scale (family/community) and large scale (utility) applications. 

In 2009, our state government convened a task force that pursued the idea of burning wood and other fuel crops, along with coal, in our existing fleet of power plants. One paper from the task force suggested that growing fuel crops on a large scale could consume 13% of Kentucky’s existing farmland. Burning wood waste and switch grass in our coal-fired power plants could potentially decrease the amount of coal used, but could also result in the production of mono-crops for fuel, deforestation and other impacts. While it could spur job creation and a stronger agricultural economy, much care would need to be taken with the selection of fuel source and process.

Any plan to use biomass energy on a large scale will have important consequences for Kentucky's forests, air, soils, and water and thus must be carefully considered.

Nolin Rural Electric Cooperative Adds Wind Power to Grid Nolin Rural Electric Cooperative Adds Wind Power to Grid

Nolin RECC, serving Breckinridge, Bullitt, Grayson, Green, Hardin, Hart, LaRue, Meade and Taylor counties, has recently joined "the nation's quest to seek alternative energy sources," (source: www.nolinrecc.com). They have just installed a wind turbine at the RECC office, located on the Fort Knox miltary base. The turbine is part of a larger effort to use clean energy sources and efficiency to replace 35% of the total base electricity consumption in 2010.
