If youre looking for a way to use the power of renewable and clean energy, you should consider making the switch to solar. In this article, well focus mostly on biomass energy that creates electricity, not biofuels. Biomass is considered a carbon-neutral energy source because it fits into the natural carbon cycle, which traditional fossil fuels do not. Pyrolysis is another way to break down organic material to generate energy. Our tips from experts and exam survivors will help you through. All These are also known as biomass feedstocks. Indirectly, its a way of harnessing the suns energy plants convert solar energy into organic material through photosynthesis, which we can then use as fuel. Once a solar farm is built, there is no need to transport fuel or to store sunlight anywhere. Biomass fuel is carbon neutral. Then we have all of the trash and waste that gets produced by human activities in each country. Organic waste such as wood, crop waste, animal waste, food waste, yard waste, and wood waste can all be used as sources of biomass energy. videos. 1. Other renewable resources, like solar, dont require these regular transportation and storage costs. Californias efforts to generate biomass energy already diverts about 10 million tons of low-value organic waste away from landfills. Here the steam can be used to drive turbines and electricity generators. Bioenergy power plants on the other hand, can be turned on and off at any time to meet energy demand. If cash crops for energy production are worth more than what we produce for food, then more farmers will consider converting their fields. The less carbon dioxide being released - the better. Ethanol is an example of turning an agricultural commodity into usable fuel. Carbon-capture technologies and new innovations can help us to divert more waste from our landfills without a significant release of particulates or greenhouse gases. However, there are cons to consider: compared to other sources for electricity, biomass can be expensive to gather, transport, and store. It can be an expensive and time-consuming process to generate resources that fit into this benefit, but these efforts are also a way to ensure our climate change activities start to reduce. BBC GCSE Bitesize Different kinds of energy sources. Biomass energy has certain advantages, at least compared to fossil fuels. Find out more . In this article, well review just a few of the advantages and disadvantages of using biomass for electricity generation. 14. Students could draw flow charts, like the one featured in this clip, to track the process of turning biomass into electricity. 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 reliance on oil throughout the world creates an economic advantage for producers and disadvantages for consumers. This opens up more land that can be used by communities. Geothermal energy is a renewable energy resource and there are no fuel costs. 3. Biomass typically doesnt require too much processing to turn it into fuel. Concrete tidal barrages can have lifespans of 100 years 3. Biomass energy production takes a lot of space, money, and effort. She has strong interests in issues related to climate and sustainability which led her to pursue a degree in environmental science at Ramapo College of New Jersey. A class debate could ensue to suggest the best way to heat and power the school. We must transport these items from their croplands or natural habits to a facility for combustion. Question 4. Can we use biomass energy in homes? GDP per capita has increased from $333 to $644 and poverty rates have fallen by 12% between 2006-2011. The energy produced from biomass is called bioenergy. Even a product like biodiesel is 10% less efficient than the standard fuel that gets used by many in the shipping industry. One of the biggest pros of biomass energy is that biomass is abundant. It creates a careful balance where we get to replace everything that gets consumed. New technologies will need to emerge to make biomass more efficient if we want to use it on a large scale. In many cases, it takes more energy to burn the organic material than the process actually produces. 3. No harmful polluting gases are produced. Some plants capture this harmful greenhouse gas in special ways to create a massive storage potential. They have been formed underground from the remains of ancient organisms over millions of years. When we create biomass energy through fast-growing natural resources that trap carbon emissions for food, then we can create a carbon neutral experience. When the U.S. government reviewed the environmental changes that happened when farmers converted from food-based corn crops to fuel-based alternatives, the emissions profile of this activity changes. The cost of gathering resources required for biofuels is very high compared to the amount of energy generated. The energy captured is then used for every kind of valuable work, including electricity generation, water desalination, and water pumping. 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. Most parts of the world do not have suitable areas where geothermal energy can be exploited. With over 200 governments having different agendas to pursue, the reality of these benefits isnt always feasible. Building refineries and production facilities that operate on the largest scale possible can make this energy resource more affordable to the average family. 5. Some manufacturers can turn the organic materials into biochemicals, biodiesel, and similar fuels. Advantages and disadvantages of biomass energy class 10. 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. The environmental and health consequences of bioenergy can be minimized through a number of efforts, including more sustainable land-use practices, re-planting efforts, and technological innovation. Biofuels are fuels made from plant materials. Overusing fertilizers can cause serious damage to local waterways and to wildlife, most notably birds. Biodiesel is less efficient than gasoline. The main benefits of biomass are: Biomass is a renewable energy source. It doesn't create any additional carbon because it's already been through the natural process of photosynthesis, meaning it's already done its job of absorbing CO2. These plantations cannot replicate the diverse ecosystems they replace, displacing animals and leading to species extinction. 1. Then, the cost of harvesting and transporting biomass materials needs to be considered. The government wants to build more nuclear power stations before 2030, but some people think they are . Some regions can supplement their supplies with animal waste and trash, but it isnt a guarantee that these items are available. High power: because water is so dense, tidal power plants can generate a lot of energy even at low speeds. This benefit is the one key that can unlock the full potential of this renewable energy resource. Biomass production uses a lot of water. Does biomass cause air pollution? Solar energy is far from being reliable compared to other energy sources like nuclear, fossil fuels, natural gas, etc. Adding more materials wont alter this fact. Well go over these concerns in more detail later. Most of this activity occurs in tropical climates where many of the nutrients are locked in the organic materials instead of the soil. It costs much less to harvest biomass than it does to mine and extract fossil fuels. When the trees and forest undergrowth arent present, then the bare soil is subjected to more erosion-related activities from the wind and water. They can also lead to a range of cardiovascular complications. Biomass, in the form of sewage, is turned into dried pellets which are burned with coal in a power station to produce heat. If you purchase a catalytic stove in the United States or Europe, then the best efficient rates hover around 75%. We must expend additional energy resources to transport biomass. Though it is renewable, there are both benefits and downsides to generating electricity using biomass energy plants. Biomass refers to any kind of organic matter that is used to create energy. Other renewable sources are carbon-zero, which is much better when looking to tackle climate change. for fuel. Phytomining describes the production of a metal crop by using high-biomass plants, which are plants that produce energy or a usable resource when burnt. Question 1. Pyramids of biomass are used to overcome the problem of inverted pyramids of number. Biomass is often touted as a renewable, carbon-neutral alternative to fossil fuels. In our already overcrowded planet, this translates into clearing forests and other natural habitats. Biomass data is difficult to obtain as the organism needs to be killed and heated in an oven to remove any water, until a constant dry mass is obtained. High Investment. As such, we wont run out of biomass to use for energy production. April 20, 2020. The impact of this change could last for more than a century. Read about our approach to external linking. New biomass energy installations are surprisingly expensive.
