How do you create references for journal articles in APA format? If you need to write a psychology paper, then you are going to probably need to reference a number of different journal articles. Such articles summarize the results of studies and experiments conducted by researchers on an enormous range of topics.
The problem that second generation biofuel processes are addressing is to extract useful feedstocks from this woody or fibrous biomass, where the useful sugars are locked in by lignin, hemicellulose and cellulose. All plants contain lignin, hemicellulose and cellulose.
This means biomass and biofuel are renewable (we can replace used biofuel over a very short period of time). It is important to note that 'renewable' energy is not the same thing as 'green' energy. Renewable energy simply wonât run out any time soon, like biofuels, hydroelectric, wind, and solar.
