We are just as dependent on the forests as they are on us, so upsetting the balance causes harm when we fail to use a sustainable approach. We also use agricultural crops and their waste items to burn as fuels or to create liquid biofuel. Although there is less mercury and sulfur, it isnt always fair to say that this resource is a green energy solution. Some regions can supplement their supplies with animal waste and trash, but it isnt a guarantee that these items are available. However, biomass has many advantages over fossil fuels due to reduction of the amount of carbon emissions. Pros of Solar Energy: Solar panel installation comes with a number of benefits. If youre looking for a way to use the power of renewable and clean energy, you should consider making the switch to solar. Disadvantages. Plants, for instance, produce biomass energy through photosynthesis. Additionally, landfills are a large contributor to greenhouse gas emissions in our atmosphere. Even a product like biodiesel is 10% less efficient than the standard fuel that gets used by many in the shipping industry. Forests, grasslands, and similar biomes all act as carbon sinks for our planet. At the present time, most renewable energy generators are expensive to set up. This claim relies heavily on the European Union (EU) classifying biomass as a carbon-neutral form of energy under their Emissions Trading System (ETS). Advantages and disadvantages of biomass bbc bitesize. When the trees and forest undergrowth arent present, then the bare soil is subjected to more erosion-related activities from the wind and water. Advantages and Disadvantages. A class debate could ensue to suggest the best way to heat and power the school. Deforestation has a range of devastating impacts on the environment, notably: Furthermore, wood is not the only type of biomass that can contribute to deforestation. Overusing fertilizers can cause serious damage to local waterways and to wildlife, most notably birds. Relying on biomass energy could lead to devastating deforestation. That means we can install nuclear power or off-shore wind facilities at a lower environmental cost for the same price. All rights reserved. The only advantage that biomass provides when looking at this specific disadvantage is the option to reduce accumulated waste levels. However, biomass is still releasing carbon dioxide into the atmosphere. 7. The following table outlines some of the biggest pros and cons of biomass energy: Biomass is organic matter that comes from plants and animals. Right now, biomass energy is not as efficient as other energy sources. 4. Recycling - what's the best way to sort waste? Fossil fuels have several drawbacks. 2 Disadvantages of Biogas. Other renewable resources, like solar, dont require these regular transportation and storage costs. Polymer types and respective properties. It returns to the surface as hot water and steam, where its energy can be used to drive turbines and electricity generators. However, there is a growing argument, including within the European scientific community, that biomass is not, in fact, carbon neutral. List of Advantages of Biomass. This reduces the amount of waste that goes into landfills, which is better for the environment. Some biomass plants rely on algae, which tend to require large amounts of phosphorus fertilizers to produce the amounts needed for energy production. Biomass, whether wood, plant, or animal material, can be sourced over and over again, making it a renewable resource. Fossil Fuels. Answer: Besides carbon dioxide and monoxide emissions, burning biomass in solid, liquid, or gaseous states can emit other hazardous pollutants and particulate matter into the air, including volatile organic compounds and nitrogen oxides. 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 main benefits of biomass are: Biomass is a renewable energy source. Furthermore, this point may be closer than you think: scientists predict that at our current rates of consumption, well run out of known reserves of oil by 2052, gas by 2060, and coal by 2090. Biomass energy production takes a lot of space, money, and effort, 6. Before taking a closer look at the advantages and disadvantages of biomass, lets start by discussing this type of material and how it can be used for fuel. Other forms of renewable energy include solar, wind, and wave energy, and many of these carry less environmental concerns and are more readily renewable than biomass. In the US, weve already cut down 94% of our old-growth forests, partly because weve cleared land for other purposes, and partly because weve harvested the wood for fuel, paper, and other uses. There is carbon dioxide that is released into the atmosphere when biomass energy is produced. Several lung diseases are directly associated with the use of biomass energy activities. Some of the efficiency rates can be as low as 10%, which means 90% of the energy produced from the organic materials gets lost. 5 Major Types of Renewable Energy [+2 Under Development], What Does Behind the Meter Mean? It keeps organic waste out of landfill, 4. Pros and cons of renewable energy resources, Advantages of non-renewable energy resources, Disadvantages of renewable energy resources, Will run out and produce dangerous waste that is hard to dispose of, Expensive to set up and wind does not always blow, Clean and cheap to run and Scotland has a lot of coastline, Clean and cheap to run and produce a lot of electricity once running, Very expensive to set up and could be hazardous to local wildlife, Expensive to set up and output could be affected by drought, Not always sunny and output does not always outweigh initial cost to set up, Applications of series and parallel circuits, Religious, moral and philosophical studies. The stoves that people use to generate energy with biomass products are inefficient. Biomass is a clean fuel and uses waste products; however, it costs money to transport and is as expensive as coal. Enter your zip code to find out what typical solar installations cost in your neighborhood. For example, wood will break down quickly and cleanly in a natural environment, but in landfill it takes longer to decompose, and when it does, it gives off the greenhouse gas methane. Biomass briquettes are very hydrophobic, meaning they repel water. 1 Advantages of Biogas. Energy Word Search. 1. Solar power is a renewable source of energy that can be gathered practically anywhere in the world. And if it is not sunny, solar cells will not produce much electricity. 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. Biomass energy lacks scalability. Designs that are non-catalytic have an assigned efficiency of 63%.

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. Polymer forms can be altered depending on their desired use. 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! This makes them ideal for use in parallel to renewable energy plants: we can use them to supplement solar, wind, or hydroelectric power at times of low production or peak demand, yet another of the many advantages of biomass. Biomass production uses a lot of water, 5. This limits where biomass energy plants can be built. 3. For the last couple of centuries, the world has heavily relied on fossil fuels such as coal and oil for industry, transport, and to power our homes. Along with carbon dioxide and methane, converting and using biomass into fuel can generate a range of polluting gasses, including: HAPs are a group of 187 toxins that have been closely linked to cancer as well as reproductive problems and birth defects. When we look at the developing worlds use of biomass, its a very different story that gets told. In fact, biomass has a lot of potential to be a reliable source of renewable energy to power our society. Biomass, or organic matter, can be used as an electricity generation source by burning organic materials to create heat, which will then make steam that turns a turbine to generate electricity. In this article, well focus mostly on biomass energy that creates electricity, not biofuels. Although biomass energy is renewable, it isnt the most environmentally friendly renewable option out there. The reliance on oil throughout the world creates an economic advantage for producers and disadvantages for consumers. Furthermore, biomass energy plants would need to be located close to sources of biomass material production to make them viable. Burning fossil fuels generates greenhouse gasses, along with a variety of other toxic components. Through combustion, whether in a home fireplace or an industrial power plant, the biomass generates heat, light, or electricity. Using these materials as a fuel is another way to keep them out of landfill by giving people an economic incentive to do so, which is yet another of the advantages of biomass. Most of this activity occurs in tropical climates where many of the nutrients are locked in the organic materials instead of the soil. We can use any organic material to produce biomass energy. Even with best practices in place, biomass might increase CO2 emissions. Constant exposure to this byproduct of heat or energy product creates a smoke inhalation hazard that can create severe health problems over time. An underwater turbine can generate . We can use it to create electricity or produce heating gas that lets us have comfortable indoor environments during each season. Performance & security by Cloudflare. No harmful polluting gases are produced. Youll just increase the output received, like when you add a couple of logs to the fire in your wood stove. High Investment. It can be burned or turned into liquid for electricity generation. These traits seen in polymers are due to the type of polymerization reaction, such as addition or condensation . Read about our approach to external linking. In all cases, combustion involves exposing organic matter to heat in the presence of oxygen. The efficiency rate of entry-level biomass is extremely low. That means about 10% of our croplands are put to use to create usable biomass. Hydroelectric power stations, as well as tidal and wave generators, are very reliable, and both hydroelectric power stations and tidal generators produce large amounts of electricity. Biomass is a renewable source of energy, derived from burning animal and plant waste. Learn more. That deprives the ecosystem of the nutrients it requires to provide a healthy foundation. Be notified when an answer is posted. Furthermore, it is much easier to extract than fossil fuels, an expensive and intensive process. Methane gas is a significant contributor to air pollution and climate change, as it traps about 30 times more heat than carbon dioxide. Since we can produce biomass-related crops almost anywhere on our planet, we can lower the transportation expenses of the industry by growing usable items near each facility. 2.2 2.Weather Dependence. Use our solar panel calculator to find out how much you can save when you power your home with solar. Renewable and fossil fuel free. American farmers produce about 5 billion bushels each year that gets turned into this useful biofuel. There are several actions that could trigger this block including submitting a certain word or phrase, a SQL command or malformed data. They can also lead to a range of cardiovascular complications. Biomass energy plants that grow their own fuel use more land-per-kilowatt hour of electricity produced. Thats why the emphasis is on garbage, manure, and dead plants. A basic contributor to mercury emission is the combustion of coal. They have been formed underground from the remains of ancient organisms over millions of years. The energy from these organisms is burned to create heat or converted into electricity. 6 Important Types of Biomass. Advantages and disadvantages of biomass energy pdf. Even though biomass is more expensive than other renewables, it is still cheaper than fossil fuels. Cloudflare Ray ID: 78b9149e0f149bdc 12. However, there are cons to consider: compared to other sources for electricity, biomass can be expensive to gather, transport, and store. These harmful substances can cause breathing issues for humans, including chronic asthma, low lung performance, chronic bronchitis, and even lung cancer. There is a growing amount of organic material being produced every day; you can find biomass nearly everywhere on the planet. It may also encourage monocultures of crops, which decreases biodiversity and strips soils of nutrients, making areas more susceptible to erosion. the water flows on the surface of the soil to the . Plus, with less waste, we would need fewer and smaller landfills. Biomass is burned to create heat [] When we burn these items, then the chemical energy kept in the biomass releases as heat. Its also important to note that biomass is not the only form of renewable energy. The impact of this change could last for more than a century. Growing crops for the sole purpose of bioenergy resources also requires a good amount of water: all plants need water to grow, and continuous irrigation of these resources can make an area more vulnerable to drought. Multiple crop cycles generate more benefits than what a single growing season can provide. In particular, biofuels tend to generate methane, a greenhouse that is even worse for the climate than CO2. Plus, since fossil fuels have fueled our world for 250 years, there's infrastructure in place to distribute it cheaply. Growing crops to produce biomass typically involves heavy water usage. Biomass production uses a lot of water. Some of them are relatively clean, including alcohol, ethanol, and methane. The Honua Ola Bioenergy plant in Hawaii will be able to produce 21.5 megawatts of electricity when it becomes operational. The BBC is not responsible for the content . Some fields can produce four crops of grass annually that is useful as an energy-producing option. The smoke must go somewhere, which means we release it outside. If cash crops for energy production are worth more than what we produce for food, then more farmers will consider converting their fields.
