Heavy fuel oil (HFO) is a category of fuel oils of a tar-like consistency. Also known as bunker fuel , or residual fuel oil , HFO is the result or remnant from the distillation and cracking process of petroleum .
For power plants, the costs of heating the oil, extra pollution control and additional maintenance required after burning it often outweigh the low cost of the fuel. Burning fuel oil, particularly residual fuel oil, produces uniformly higher carbon dioxide emissions than natural gas.

The U.S. Energy Information Administration gives a general explanation for how to translate a heat rate value into a power plant's efficiency value. [4] Most power plants have a target or design heat rate. If the actual heat rate does not match the target, the difference between the actual and target heat rate is the heat rate deviation.
Bioenergy is a type of renewable energy that is derived from plants and animal waste. [1] The biomass that is used as input materials consists of recently living (but now dead) organisms, mainly plants. [2] Thus, fossil fuels are not regarded as biomass under this definition.
