Energy Alternatives: * Alternative energy is any energy source that is an alternative to fossil fuel. In a general sense in contemporary society‚ alternative energy is that which is produced without the undesirable consequences of the burning of fossil fuels‚ such as high carbon dioxide emissions‚ which is considered to be the major contributing factor of global warming. * This chapter discussed only a few of the possible alternatives to our current combustible energy generation system

Alternate Energy What would it be like to live in the dark? Finding new forms of alternative energy has been a major concern throughout the world for the past several years. Currently‚ our main sources of energy are coal for electricity‚ and oil for transportation. Alternative energy‚ also known as renewable energy‚ is defined as energy derived from sources that do not use up natural resources or harm the environment. At the rate we are using these nonrenewable resources oil is scheduled to run

Alternative Energy Alternative Energy Our environment is ever changing so it would only make sense that our climate will change also. Researchers believe that the changes in our climate are directly related to certain types of energy. Energy plays an important role in many aspects of our lives. For example‚ we use electricity for lighting‚ heating‚ and cooling. We use fuel for transportation‚ heating‚ and cooking. Our energy production and use are connected with many other aspects of modern

2012 Alternative Energy Sources In the world today‚ alternative energy sources are becoming more and more of a necessity. Right now‚ the world’s energy demand is greatly increasing mostly because of population growth. Even though the rate of population growth is very diverse in different countries‚ the world’s population doubles about every thirty years. The world energy use is doubling every fourteen years (Hodgson). Still‚ the main energy source is oil. The other primary source of energy is coal

Renewable energy is energy that originates from natural sources‚ which is a continuing and nonpolluting energy that is replenished due to its perpetual natural motion. These sources are commonly solar‚ geothermal‚ wind and tidal energies. Comparing different countries’ use of renewable energies -- in Portugal this year‚ close to 45 percent of its electricity will come from renewable energy sources (Rosenthal‚ 2010). This compared to 10.1 percent in the United States (U.S. Energy Administration

Alternative Energy Alternative Energy Alternative energy refers to energy sources that have no undesired consequences such for example fossil fuels‚ nuclear energy and falling water. Fossil fuels are coal‚ petroleum and natural gas. There are some characteristics of the fossil fuels that made the concept of alternative energy come into place. (Alternative Energy) One of the fossil fuels‚ Petroleum‚ forms a thin film around the grains of the rock where it formed. Pressure from the overlying rock

Types of Alternative Energy “Every day‚ the world produces carbon dioxide that is released to the earth’s atmosphere and will still be there in one hundred years’ time. This increased content of carbon dioxide increases the warmth of our planet and is the main cause of the so called “Global Warming Effect.” One answer to global warming is to replace current technologies with alternatives that have comparable or better performance‚ but do not emit carbon dioxide. We call this Alternate Energy.” (Alternative

Energy Debate in the United States Since the 1950’s The United States have consumed energy mainly driven by oil. The demand has almost tripled since then and because of that‚ the United States have depended on energy supplies from countries that are not reliable and are unstable. The risks and cost of oil rising is a concern for most people to think we should turn to a different energy resource that is cheaper and more reliable than oil. The United States would be better off if we could lead

Premium Energy Fossil fuel Natural gas
Today‚ renewable energy sources are commonly used to replace fossil fuels due to the lacking of oil‚ gas‚ etc. An alternative energy source is ethanol (C2H5OH). It is an alcohol fuel manufactured by fermentation and distillation of crops that are high with starch and sugar‚ such as grains‚ sugarcane (most commonly used)‚ corn‚ and fruit. Other names for ethanol are ethyl alcohol‚ drinking alcohol‚ and grain alcohol. It can also be made from trees‚ grasses‚ woods‚ and plant waste. It is a colourless
