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.

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.
1 Biofuels can be low in carbon intensity (the net amount of carbon released to the atmosphere) - as long as uptake by other growing plants balances the carbon that is released in biofuel production and use. 2  Locally-grown biofuel can enhance energy security by increasing independence from petroleum.urning biofuel releases carbon dioxide to the atmosphere, just as burning any other fuel does. However, unlike fossil fuel, biofuel can be renewable and low in carbon intensity -- if it is derived from plants that are grown sustainably (with new growth continuously replacing harvested material).
