Biomass is a term that refers to biological material that can be used as a source of energy. It may be as easy as a wooden log or anything more complicated like alcohol.
Despite the fact that all fossil fuels, such as coal and oil, are thought to come from underground ancient animals, they are often omitted from the concept of biomass, which has been the planet's main energy supply for centuries.
Biomaterials are commonly obtained from plants. Corn, for example, can be converted into liquid automotive fuel, and wood can be used to generate heat. Forest residue, such as grass clippings and falling leaves, are another source. Willow, corn, and hemp are only a few examples of plants that can be converted into industrial fuel. These kinds of structures can be harnessed and used to generate electricity. This energy supply is totally green so it can be grown again. Garbage, which is roughly 60% biomass, is another significant source of biomass in the household.
IN WHAT WAYS Will BIOMASS BE USED TO Provide ENERGY?
Burning biomass for energy is the simplest and most effective process. It produces heat as it is burnt. Certain kinds of garbage may be burnt to heat homes for certain households, though this is not necessarily feasible in typical homes.
Biomass may also be burning in waste-to-energy systems, which are specialized plants. These plants convert heat into steam, which can then be used to heat buildings or generate electricity. Garbage is burned to generate enough electricity to fuel over 3 million homes in the approximately one hundred waste-to-energy facilities currently operating in the United States.
Waste-to-energy plants not only generate electricity from a green fuel, but they also reduce the volume of garbage dumped in landfills per year. The fact that the average American generates over 1,600 pounds of waste per year makes waste-to-energy plants much more beneficial than the electricity they provide.
Biomass can be used to produce methane gas, ethanol, and biodiesel in addition to energy and heat. The primary component of natural gas, methane gas, is generated by rotting waste and can be harvested.
Ethanol is made from sugar cane and maize, and it is used to power automobiles. Biodiesel, another fuel used to power engines, is made from leftover oils and fats.
THE BENEFITS AND DISADVANTAGES
The biggest advantage of biomass is that it is a renewable source of energy. Not only does this provide us with a clean source of energy to heat our houses, fuel our cars, and generate electricity, but it also assists us in reducing the amount of garbage we are leaving for future generations to deal with. However, if not properly handled, biomass can be harvested at excessive rates, causing habitat destruction and water consumption. Another disadvantage of using wood as a fuel is that it causes waste in the form of carbon monoxide, nitrogen oxides, and volatile organic compounds in the atmosphere.
Though firewood is often used to heat houses, other forms of bio-materials are less common, and their commercial use is currently limited. Apart from high utility-scale costs, our energy demand is outpacing biomass production along with the fastest-growing established energy crops. In 2009, biomass waste accounted for just around 0.5 percent of overall US energy consumption, while biofuels accounted for 1.6 percent. Using current plant types to meet a substantial portion of the rising primary energy demand would necessitate unreasonably vast land areas.
