Sustainable Energy Sources Energy is life. Life on this planet depends upon a fixed amount of energy. The modern industrialized energy sources such as coal and petroleum were originally utilized for their seeming promiscuity and high energies yielded per unit volume. The world has now become painfully aware of how finite petroleum reserves are, not to mention the political complications associated with being dependent upon foreign countries for an energy supply. To add insult to injury, the
Renewable Energy Source Wind is called a renewable energy source because wind will continually be produced as long as the sun shines on the earth. The sun’s contribution to wind energy deals with converting air into heat or cool wind. Wind is produced by the irregular heating of the earth’s surface by the sun. On land, the warm air spreads and goes up in the sky, in the water, heavier and cooler air moves in to take the warm air’s place, thus providing local winds. This power source should be
alternative energy sources are essential to the vigor of our environment. Coal, oil, and natural gas are the most used sources of energy today. But according to Energy News “Our current rate of fossil fuel usage will lead to an energy crisis this century. In order to survive the energy crisis, many companies in the energy industry are inventing new ways to extract energy from renewable sources.” The future vitality of the environment will be derived from wind power, geothermal energy, biomass, nuclear
Renewable energy sources have been found to cost more than the benefits that are received from the energy sources. There are many different resources that you can use including water, wind, solar, geothermal, and biomass. These energy sources can differ in cost depending on capital, fuel, and operations and maintenance. Some of these sources are not cheap to build but once they are up and running, they have no fuel cost. There are many reasons to determine when, where, or how an energy source is used
the United States uses massive amounts of energy. Only about 8% of the United States’ energy needs are met by renewable energy sources. That means that eventually 92% of the nation’s energy resources will run out. Recently this problem has been brought into the public’s eye and the American people’s attention has shifted to renewable and “green” energy resources. President Jimmy Carter (1977) said that “[w]ith the exception of preventing war, this (the energy crisis) is the greatest challenge our country
and with the problem of inflation, the bill prices would only increase and thus become more expensive. Solar power is energy efficient, what is meant by that is that solar power cannot ever run out as long as it is installed properly. Solar power cells is a source of electrical energy that converts a powerful source of energy such as the sun into electricity, using it’s energy to create electrical currents within the solar panel. Solar panels produce electricity using technology called “Solar Photovoltaic
INTRODUCTION Renewable energy is energy produced from natural resources such as, wind, sunlight, rain, tides and geothermal heat which can be re-used or replenished. Natural energies (renewable energies) have its advantages and disadvantages. The reliance on fossil fuel is reduced by the sources of renewable energy. Though the use of natural sources has many advantages over the use of fossil fuels, the cost of investment for it can be too high for some people. In this project, I will be highlighting
Traditional and alternative energy source development should, essentially, be government supported and policy governed. Actions prove to us that government aid in the development of alternative energy sources greatly benefits the economy, providing more job opportunities to citizens; as a result, this leads to a sustainable environment, improves standard of living, and provides education to citizens on human impact on the environment. These changes provide countries with the foundation towards sustainability
Earth’s resources, for instance water, productive farming land and energy, outlines the basic foundations of our continued existence on earth. However, with the continued human activities, for example logging and charcoal burning, these resources are quickly being depleted. Human inhabitation and increased consumption of the natural resources is resulting in untold destruction. The climate change being experienced globally, the rapidly depleting freshwater catchments, the dwindling forest cover,
Hydropower as an Alternative Energy Source Water provides a very valuable resource. We use dams built to run water through turbines and produce electricity. There are many advantages and disadvantages to hydropower, though there are more advantages. It is reasonable inexpensive to maintain, and is a clean source. There are issues with dams blocking fish swimming in the river, but there are ways to help them. Hydropower is well balanced between the electricity needs and the needs of the environment
Non-renewable energy sources such as fossil fuels and nuclear ores have a rate of replenishment on the order of millions of years. These are currently being used at a rate significantly greater than that of replenishment. Consequently, there is a finite reserve of non-renewable energy sources, and once these reserves have been emptied, alternative sources of energy must be used. Renewable energy sources replenish at a rate greater than they are consumed. Renewable energy sources include solar energy, some
Alternative Energy Source Abstract As the world’s source of fossil fuels diminishes, another source of energy must replace fossil fuels. This paper evaluates biofuel, one alternative form of energy by showing what biofuel is, how it works, its historical use, and benefits and drawbacks it pertains. I hypothesized that biofuel would be an effective alternative energy. My conclusion does not support my claim, but in terms of worldwide usage. Introduction: With the world’s source of fossil fuels
There are many types of Alternative Energy Sources. The different energy sources are hydro and solar power, wind, biomass and geothermal energy. Throughout the world people don’t recognize that we use every these energy sources day for our own personal use. The energy sources are not only free but they are also renewable. It is a little more costly to use these energy sources, but going green is what’s best for our environment. Using these alternative sources will create fresher air, eliminate over
relied on natural gas and fossil fuels. These fuels, while effective for producing energy, are detrimental for the environment and are limited in amount. People, including some aboriginal communities, have been turning to alternative energy sources to generate electricity. The use of these alternative energy sources has some potential issues. One of the biggest issues with the use of alternative energy sources within aboriginal communities is the negative effects it may have on their culture and
natural gas, to produce most of the world’s energy. Solar energy is cleaner and virtually self sustaining after installation, not taking much maintenance. It is becoming more affordable as well, prices have dropped seventy percent over the last five years (Sorenson 215). It is also very hard to find a new location, and when one is found the amount of energy drawn is sometimes sparce or fluctuates wildy. Wind energy is another semi-viable option. Wind energy is clean and may be more efficient in less
America an energy source is what keeps the country running and fueled. Whether it’s from helping light sources to keep traffic regulated to gas which helps cook and heat on an everyday basis. With this being said an energy source comes in many different shapes and forms but all have the same intention and purpose both with its own distinct and unique way of how it’s gathered, used and stored. In my essay I will be sharing with you the key things non renewable and renewable energy sources share as
change, researchers are looking into alternate energy sources that are renewable, globally available, and environmentally friendly. It is predicted that by 2035, the worldwide demand for energy will increase by 36% ("Discovering Global Energy Solutions"). Algae, a photosynthetic microorganism, have captured the attention of many due to its ubiquity and versatility. Initial interest in algae was piqued during the 1970s when the United States suffered an energy crisis. The Aquatic Species Program was established
Energy is what makes the world go around. Without the continuous supply of energy that most of us take for granted, things would quickly come to a stop. We are dependent on energy for our very survival. Heating our homes, transportation, communication, health, even our daily food supply, which all depends on energy. But while energy delivers much that is good, it is also a primary factor, the primary factor. Which destroy our life systems. From smog, to acid rain, to climate change, to nuclear radiation
some believe it is not a sustainable source of energy. The earth’s energy future cannot and will never be sustained by just one energy source. A secure energy future relies on a controversial source, nuclear reactors and an unpolished source, kinetic energy. Nuclear energy is ideal and very cost effective. As humans, we have nearly mastered the art of nuclear fission. Currently, nuclear energy plants are responsible for about three-quarters of carbon free energy. This statistic shows that solar and
Using Alternative Energy Sources in the U.S. The United States has many directions to choose from in the oncoming future of energy. “Options for the world's energy future may include surprises, thanks to innovative research under way around the world” (LePoire 1). History has shown that surprises can change generations . Since the mid 1900’s, experts have been conducting research on the way our nation has been using energy. The United States have relied on other countries to gain knowledge with
