Biological Power


Plants provide us with many things, food that we eat, air that we breathe and many more others, including energy. Through the process of photosynthesis, plants absorb energy from the sun; the energy stored can be used as a renewable energy source called biomass (cited by http://en.wikipedia.org/wiki/Renewable_energy).
Biomass is derived from living, or recently living organisms. It can be used directly as an energy source, or turned into other products like biofuel. Example of biomass sources are trees, food crops, algae, agricultural, forestry byproducts, and garbage (cited by http://en.wikipedia.org/wiki/Biomass, www. nationalgeographic.com).

So how is biomass converted to energy? According to http://dsc.discovery.com, biorefining is the process of “refining” biomass to produce fuel, energy and chemicals. Burning wood is an example of turning biomass into energy. Steam that is generated from burning can be used to power turbines to generate electricity.

Methane gas, found in dead organisms, can be used as an alternative for petroleum fuels.



Biomass lessens solid waste products, using it as energy, fuels and electricity are cheaper, but its environmental impact is as great as fossil fuels. Biomass produces carbon monoxide, nitrogen oxide and other pollutants in the air, resulting in global warming (cited by http://en.wikipedia.org/wiki/Biomass).

  4. This is a very good article. Was able to know that we really need to take care of the plants since it provides us so much things. and that we should be more careful in disposing our garbage. :)

  5. it's true that plants captures the sun's energy, and it is that energy that we recover in the form of biofuels to reduce the imported petroleum. but it is also good to consider the power used in the process. kung mas mahal pa yung magagamit na energy sa pagpaprocess ng plants, parang sayang din..

  6. it is indeed cheap in terms of production, but as stated in the article the results of converting the solid waste is the same with fossil fuels. maybe they should think of new ways of converting solid wastes that will only produce less pollution. :)

  7. This is a very eco-friendly article. However, the article is lacking of negative points or disadvantages of using biological power. But in the end, biological power is a practical way of converting natural resources and other forms into electricity, provided with necessary measures.

  8. Biological power really contributes in satisfying the needs of people here on earth. This blog gave me enough information to know how energy is formed/created. we all know that energy is one of the most essential thing that is used in this continuously growing world. But despite of all the contributions that biological power may provide, people must not be concerned more on developing the economy, they should give more priority to the preservation of our limited available resources.
