It can burn directly or get converted into liquid fuels, biogas, and other products. Other renewable resources, like solar, dont require these regular transportation and storage costs. Carbon Neutral. Biomass energy is renewable energy from plants and animals. The biomass is exposed to heat in a low-oxygen environment so that it converts to a gas rather than combusting. The main advantages of biomass energy are that it is renewable, reliable, abundant, and carbon-neutral. This is an added cost that other renewable technologies dont need to account for, seeing as they rely on free, on-site resources (tides, sunshine, wind, etc.) The photosynthesis process helps to prevent severe climate change incidents. If we want to create something that meets the needs of an entire nation, then new furnaces and boilers must get added to a biomass facility so that additional electricity generation becomes possible. 1. Radioactive decay of these substances releases heat energy, which warms up the rocks. Whats more, these biomass energy plants would take up large footprints within our towns and cities a planning nightmare for new population centers, and virtually impossible in existing ones! The biomass (amount of living material) of organisms in each trophic level is measured and presented in a pyramid of biomass. Biomass pellets and wood chips are also burned locally to produce heat for a swimming pool. Solar Power Pros & Cons. A cheap source of energy: Fossil fuels are relatively cheap. In our already overcrowded planet, this translates into clearing forests and other natural habitats. Read about our approach to external linking. American farmers produce about 5 billion bushels each year that gets turned into this useful biofuel. A power station can burn a fossil fuel to heat water, producing steam. While the affordability of solar power, pros of wind energy, and similar renewable resources are big news, there are other fuel sources out there that also have great potential. Add to this that clearing forests contributes to reduced rainfall, and bioenergy production on a large scale could not only cause local droughts, but also wide water issues, potentially on a global scale. The heat produced can be the end goal, or it may be used to create steam to turn turbines to generate electricity. Private limited companies have limited liability, meaning an investor only loses the initial stake if a company goes bust. Further harmful emissions are generated when using the biofuel. About one-fifth of the fossil fuels we use today go directly toward transportation needs. Otherwise, this would mean transporting organic materials long distance, and potentially using more energy to do so than the plant generates. 13. However, even if biomass can be favorably compared to fossil fuels in this regard, theres no contest when it comes to cleaner forms of renewable energy. Through combustion, whether in a home fireplace or an industrial power plant, the biomass generates heat, light, or electricity. Most of this activity occurs in tropical climates where many of the nutrients are locked in the organic materials instead of the soil. The advantages and disadvantages of biomass energy attempt to turn our waste generation activities into a positive situation. The efficiency rate of entry-level biomass is extremely low. Energy independence. Moreover, the expansion of biofuels technologies will create a stable, domestic energy supply, reducing the vast amount of money spent importing oil from overseas and increasing our countrys national security.
