If you found it useful to learn about the advantages of biomass, take a look at what we have to say about other, cleaner forms of renewable energy, take a look at our guides to solar panels, solar farm land requirements, wind turbines, and hydroelectric power. Answer: Biomass continues to be an essential fuel in many countries, especially for cooking and heating in developing countries. As consumption levels continue to rise around the world, the growing availability of animal and plant waste allows us to have more access to this energy generation resource. Additionally, building biomass energy plants for large-scale electricity production can require a good amount of land space. For one, depending on the type of biomass used to generate electricity, unsustainable bioenergy practices can result in deforestation over time. Some manufacturers can turn the organic materials into biochemicals, biodiesel, and similar fuels. There is carbon dioxide that is released into the atmosphere when biomass energy is produced. The energy produced from biomass is called bioenergy. Lack of Reliability. Electricity can be generated using a turbine to drive a generator before distribution. Although biofuels are arguably better than fossil fuels, there are other forms of renewable energy that offer many of the same benefits as biomass without most of the pitfalls. The fact that the biomass supply can be regenerated within a human lifetime is what makes biomass renewable. You can recycle wood and other organic materials, but its not always easy to do. Additionally, biomass is a more reliable source of energy than fossil fuels, especially as the latter are getting more and more scarce. The average utility rate for electricity in the United States is $0.1331 per kilowatt-hour, but it is as high as $0.2254 in Alaska and $0.3276 in Hawaii. Here's the need-to-know stuff about the energy source, biomass! When we look at the developing worlds use of biomass, its a very different story that gets told. Producers have a higher value than the primary consumers; primary consumers have a higher value than the secondary consumers and so on. 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. When we burn these items, then the chemical energy kept in the biomass releases as heat. We typically use wood and processing wastes from it to provide warmth to buildings, produce process heat for industrial purposes, or generate electricity. It is more accurate as the organisms size is taken into account. If we burn these plants to produce energy while replacing them with crops that have a lower storage capacity, then the results are similar to what happens when we use fossil fuels. That means the most biomass energy resources tend to belong to the warmer climates where more agricultural activities become possible. 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. Renewable and non-renewable energy sources have pros and cons in terms of cost, reliability and pollution. Sea Wall Advantages and Disadvantages: What You Should Know? We must expend additional energy resources to transport biomass. Is it better to lease or buy solar panels? 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. Alternatively the students could design a poster advertising the fuel which they think is the most effective energy source. Biomass energy may not capture carbon dioxide efficiently. Clearly, this is not sustainable, so we need to find renewable sources of energy. In this article, well review just a few of the advantages and disadvantages of using biomass for electricity generation. Even their methods can still increase localized greenhouse gas emissions by over 50%. New technology means production of biomass energy is more efficient and less . 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. When looking at renewable energy sources, its important to look at all of their advantages and disadvantages. If we can produce this resource sustainably, then we have an effective way to create fuel while promoting a healthier environment. Some advantages of using biomass energy in our daily lives are listed below: Though biomass is a renewable source of energy, it has certain disadvantages, which are listed below: The prospective of biomass energy is there for all of us to see. Description. One reason why biomass is so widely available is because the planet produces a lot of waste. Mercury is extremely toxic and significantly damaging to the environment. Read about our approach to external linking. We can take waste products like sawdust, turn them into pellets, and then combust them to generate basic heat.

This process works most effectively within the tropical forests of our planet. Given that water shortages are predicted to be one of the planets biggest challenges in the 21st century and beyond thanks to climate change, this is an issue that we should take very seriously. Plastic waste gets a lot of attention, and rightly so, but organic waste is also a problem. Biofuels are fuels made from plant materials. In fact, biomass has a lot of potential to be a reliable source of renewable energy to power our society. Additional space may also be necessary to grow the organic matter itself; if power companies are growing crops or trees for the sole purpose of bioenergy, rather than using agricultural waste, this contributes to a larger land footprint per unit of electricity production. 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. When we combine the issues with this disadvantage with the potential for forest clear-cutting and other mismanagement issues, the impact on the environment can be significantly worse than if we were to use fossil fuels alone. In this page, learn more top 7 pros and cons of cloning, and Diversifying energy supply and reducing dependence on imported fuels. 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. Plus, it helps reduce waste. Harvesting biomass for electricity can also help us reduce waste. The reliance on coffee is not as high as before as the economy is increasingly divergent. Well go over these concerns in more detail later. The amount of versatility available from the core products of this industry makes it one of the most useful energy items we can use right now. It loses about 20% of its original mass, but retains 90% of its energy. This could include everyday animal matter as well as different agricultural crops. A GCSE study aide on the educational website features a bullet- . Several different organic materials are useful for biomass energy today. Phytominers cultivate crops of a specific plant species with high concentrations of a desired metal, harvest the plant and deliver it to a furnace to burn and gather its bio-ore. As a potential . This chemical reaction leads to the creation of synthesis gas, or syngas, which can be used as fuel. That means about 10% of our croplands are put to use to create usable biomass. Deforestation also results in the loss of biodiversity that strengthens our global ecosystem. 14. High Investment. These include biodiesel, made from plant oils, and bioethanol, made by fermenting sugar and . Using solar cells might have some drawbacks. Biomass energy is renewable energy from plants and animals. This means that biomass wont have the issue of limited availability, like fossil fuels do. When the wind isnt blowing, no wind energy is being created by turbines. The fuel efficiency rates of biofuels like ethanol are up to 33% less than when we use refined gasoline. The only advantage that biomass provides when looking at this specific disadvantage is the option to reduce accumulated waste levels. Outside of the upfront costs to get the plants up and running, there are additional costs associated with extracting, transporting, and storing biomass prior to electricity generation. 2017-05-04 11:52:57.
