Examples of biomass include landfill gas, wood, crops, garbage and alcohol fuels. Biomass is renewable energy that comes from plants and animals.Continue Reading
Many types of biomass, such as wood, are burned when used for energy. Wood is the most common biomass and has been used for thousands of years. In the United States, wood and wood products, such as sawdust and wood chips, provide the country with about 2 percent of its energy each year. Wood is used by business and industry, and to heat homes and cook food. Although wood is still a popular biomass, some countries prohibit its use during high-pollution days because it releases carbon dioxide into the atmosphere.
Garbage provides another source of biomass. Organic materials like leaves, lawn clippings and food scraps are burned and turned into energy.
Crops are also a form of biomass, and new technology is being developed that turns crops into biofuel. Biofuels made from plants release healthier emissions into the atmosphere. Burning biofuels results in releasing oxygen into the atmosphere, which is good for the planet.
When biofuels like wood and trash are burned, they leave behind ash. The ash often contains harmful compounds, so companies work hard to separate organic matter from inorganic matter to cut down on the amount of harmful ash left over after burning biomass.Learn more about Sustainability
Like most energy resources, biomass energy has the potential to do harm, especially to the environment. Harvesting biomass for energy at unsustainable rates would damage ecosystems. It can also produce harmful air pollution, consume large amounts of water and produce net greenhouse emissions.Full Answer >
Recycling is important for making the environment a cleaner place, conserving materials, saving energy and reducing the amount of garbage in landfills. One of the most important benefits of recycling is the impact it has on the Earth. Recycling different materials helps the environment by reducing the use of natural resources. For example, recycling paper goods reduces the number of trees cut down each year.Full Answer >
Since nuclear energy does not depend on fossil fuels, it offers benefits including reductions in greenhouse gas emissions and dependence on fluctuating oil or gas prices. As of 2014, the worldwide fleet of nuclear reactors reduces carbon dioxide emissions by 2 billion metric tons each year.Full Answer >
Fossil fuels are non-renewable because they take millions of years to form. Fossil fuels make up most sources of non-renewable energy, and they were created millions of years ago as a result of marine creatures decaying under immense pressure and heat.Full Answer >
