Today, were still clearing old growth forests for quick-growing monocultures such as pine and eucalyptus. Its worth noting that some forms of biomass can be renewed more quickly than others. Other renewable sources are carbon-zero, which is much better when looking to tackle climate change. If you purchase a catalytic stove in the United States or Europe, then the best efficient rates hover around 75%. When the wind isnt blowing, no wind energy is being created by turbines. This means that biomass wont have the issue of limited availability, like fossil fuels do. If the environmental costs of this disadvantage get added into the overall expenses in place, then the greenhouse gas emissions could be worse with this renewable resource than it is when we burn a cleaner fossil fuel like natural gas. For now, it comes with a big set of drawbacks that make it difficult for it to be widely implemented. We can burn solid biomass to produce heat directly. Most notably, biofuels produce greenhouse gasses and other pollutants, as well as contributing to deforestation and water shortages. The main advantages of biomass energy are that it is renewable, reliable, abundant, and carbon-neutral. 1. When the particulate matter from organic combustion comes into play, then the environmental risks of a biomass facility become similar to those of coal-fired power plants. Are energy-efficient appliances worth it? Even industry leaders have admitted that not all types of biomass are carbon neutral. It can be a carbon-neutral energy resource. Well go over these concerns in more detail later. Advantages and Disadvantages of Wave Energy: Wave energy or wave power is the transportation and capturing of energy by ocean surface waves. The photosynthesis process helps to prevent severe climate change incidents. Although there are some advantages of biomass, and it is a renewable source of energy, there are also a range of concerns associated with biofuels, from deforestation and habitat destruction caused through raw material production to the carbon and pollutants produced by converting and using the fuels. Some manufacturers can turn the organic materials into biochemicals, biodiesel, and similar fuels. Others argue that although biomass is often not carbon-neutral when used for fuel, it is a low-carbon fuel that produces less carbon pollution than fossil fuels. The Honua Ola Bioenergy plant in Hawaii will be able to produce 21.5 megawatts of electricity when it becomes operational. Then, when new plants grow, they absorb carbon dioxide back out of the atmosphere, and enter the cycle again. Building refineries and production facilities that operate on the largest scale possible can make this energy resource more affordable to the average family. If we dont take care of this component of our ecosystem, then it may become difficult for future generations to have access to the water they need. (signed). Even with best practices in place, biomass might increase CO2 emissions. While converting organic materials into higher-grade materials can be pretty intensive, there are cheap and relatively easy ways to harness biomass as a fuel, namely through combustion. This includes not only burning wood for heat, but also more sophisticated processes such as converting biomass to alcohol through fermentation and then burning this in a combustion engine. The energy captured is then used for every kind of valuable work, including electricity generation, water desalination, and water pumping. Advantages Disadvantages ; It is more accurate as the organism's size is taken into account. Additionally, building biomass energy plants for large-scale electricity production can require a good amount of land space. If it is not a windy day, wind turbines will not turn. The impact of this change could last for more than a century. Adding more materials wont alter this fact. GDP per capita has increased from $333 to $644 and poverty rates have fallen by 12% between 2006-2011. 14 Essential Biomass Pros and Cons in 2020. Arguably, wed be better off investing in clean, renewable forms of energy such as solar, wind, and hydroelectricity. This is a mixture of carbon monoxide, carbon dioxide, and hydrogen, and although it cannot be burnt directly, it can be used as a fuel source. An underwater turbine can generate . Just like fermentation used to produce alcoholic beverages, biomass can be exposed to yeast to convert its sugar content into ethanol. 1. Biomass, in the form of sewage, is turned into dried pellets which are burned with coal in a power station to produce heat. Most of the companies that offer solar energy solutions haven't reached that quality benchmark. High Investment. Youll just increase the output received, like when you add a couple of logs to the fire in your wood stove. Over the years, biomass has become a popular alternative energy source. Due to the cars that are run by petrol and diesel, oil and its different products are used by the masses. Also, more needs to be done to solve the problem of efficiency as fuel, and other issues like space and cost are required to be solved. Biomass is a clean fuel and uses waste products; however, it costs money to transport and is as expensive as coal. Natural gas produces a greater greenhouse effect, whereas biogas is a more eco-friendly energy source. About one-fifth of the fossil fuels we use today go directly toward transportation needs. We can only produce biomass energy at a specific ratio because of the organic materials used to create it. Students could write a table to describe these aspects of biofuel, going on to compare them to renewable energy sources such as wind, wave and solar energy.
