Biomass is one of the renewable energy. Which the world needs more renewable energy. However, we also need to examine whether biomass energy is green energy. Some examples of sources for biomass energy is as follows: From the agricultural waste, agricultural waste a lot that can be used for biomass energy sources, such as straw, animal manure and poultry. From energy crops, for example is jatropa , corn, etc Wood, wood can be burned, and generate heat energy, but it will produce carbon dioxide and the greenhouse effect. In the processing of biomass energy and energy conversion, we can do with the direct combustion, termokimiawi conversion and biochemical conversion. Direct combustion is the simplest energy conversion. But it will produce the greenhouse effect. Bebrapa biomasssa utilization is: Gasification, pyrolysis, liquification, etc.
For some people, math is a difficult subject to master. If parents who have problems like that, of course, will have trouble when they serve as a math homework help for their children. It would be nice when the children ask their parents about the algebra 1 or algebra 2 , they can answer it. But, how do we study mathematics? Should we go back to school? I think, there are many ways to learn math again. For example, by using an online tutorial that provides math statistics help , calculus help , geometry help , Algebra 2 Help and others. I think, our kids will be more proud of us, when we could help for their math homework.
