Biomass Energy Introduction Biomass is biological material derived from living‚ or recently living organisms. It mostly often refers to plants or plant-derived materials which are specifically called lignocellulosic biomass. As a renewable energy source‚ biomass can either be used directly via combustion to produce heat‚ or indirectly after converting it to various forms of biofuel. The source of biomass energy. Wood energy. is the largest

Environmental crises are distinguished by rapid and largely unexpected changes in environmental quality that are di¢ cult if not impossible to reverse. Examples would be major extinctions and significant degradations of an ecosystem. The world is facing a very serious environmental crisis. Key environmental problems include air pollution‚ the destruction of the ozone layer‚ vast quantities of toxic waste‚ massive levels of soil erosion‚ the possible exhaustion of key natural resources such as oil

Coal is an un-renewable fossil fuel which is known as a cheap and reliable energy source. It has many environmental impacts‚ both positive and negative. Coal has a great economical effect providing thousands of people with jobs‚ and harmfully leaving individuals with un-producible land. It has a social impact negatively when people live near coal mines. Coal is a flammable‚ mostly black rock‚ which has been located in 50 different countries around the world. Coal is known as a fossil fuel because

TESTING YOUR COMPREHENSION 1) Why are fossil fuels our most prevalent source of energy today? Why are they considered nonrenewable sources of energy? Today‚ the three main fossil fuels that are in demand are oil‚ coal and natural gas. These fossil fuels are prevalent because they are efficient to burn‚ ship‚ and store based on high energy content. Fossil fuels also provide for our daily needs such as transportation‚ heating‚ cooking and electricity. Based on our current rates of consumption‚ we

Renewable sources of energy Wind energy Wind Energy‚ energy contained in the force of the winds blowing across the earth’s surface. When harnessed‚ wind energy can be converted into mechanical energy for performing work such as pumping water‚ grinding grain‚ and milling lumber. By connecting a spinning rotor (an assembly of blades attached to a hub) to an electric generator‚ modern wind turbines convert wind energy‚ which turns the rotor‚ into electrical energy. Because wind is a clean and

Student Professor English 101 10 October 2010 Obama’s Domestication of Energy The United States of America is the world’s biggest consumer and producer of energy. It is also the world’s biggest net importer of natural resources (Shaffer‚ “The United States” 135). The domestication of energy is the production and consumption of energy from resources found in the home country. Domestic energy can occur from petroleum reserves on public and private lands‚ from using hydraulic fracturing of shale

Pollution - Environmental pollution is any discharge of material or energy into water‚ land‚ or air that causes or may cause acute (short-term) or chronic (long-term) detriment to the Earth ’s ecological balance or that lowers the quality of life. Pollutants may cause primary damage‚ with direct identifiable impact on the environment‚ or secondary damage in the form of minor perturbations in the delicate balance of the biological food web that are detectable only over long time periods.
