Essay on Alternative Sources of Energy

producing energy at a low cost. Twenty to thirty years ago it was hard to imagine what sources of energy (other than obvious possibilities like solar panels and windmills) that could efficiently supply the world. The advancement of technology today is opening new doors in the energy field that are likely to change the way we think about energy. With so many different sources of energy that are prevalent around the world, the challenge is found in harvesting and securing the energy at its source, and doing…

developing world, vast amounts of energy resources are being utilized at an alarming rate, one which can certainly result in the extinction of our valuable natural resources. Moreover, majority of the energy resources utilized today are non-renewable natural resources like the petroleum products which account for nearly eighty percent of all the energy resources used. Thus, exploring alternative forms of energy so as to decrease our dependency on non-renewable forms of energy and consequently save the environment…

What are alternative energy sources? Alternative energy sources are forms of energy that use natural resources to produce energy. There are three main alternative energy sources that can be used in the place of fossil fuels, which are Nuclear, Solar, Wind, and Hydroelectric. Fossil fuels such as coal, oil, and gas are decreasing and eventually will run out. Usage of fossil fuels cause harm to the environment by producing greenhouse gasses. Alternative energy sources are not harmful to the environment…

The world has relied on the same sources of fuels and delivery systems for at least the past one hundred years. Since the turn of the Industrial Revolution, the world has been dependent on coal, oil, and other natural resources. These sources of fuel have worked fine for the world, until now. At the rate it that these fuels are used the world may one day run out of these precious resources. Our society must prepare now to utilize an alternate source for its fuel. The longer the world waits, the…

warming. As gas prices steadily rise, people need a newer, cleaner source of energy. The alternatives are numerous and would be beneficial to the well being of the whole world. The human race must replace its fossil fuel use with renewable resources in order to prosper economically and to improve the world ecologically. Renewable resources are much cleaner and more ecologically friendly than fossil fuels. Renewable sources of energy do not pollute the environment and also do not release toxic carbon…

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…

Geothermal Energy Introduction The useful and super eco-friendly, and environmentally safe (for the most part), form of energy that is called Geothermal Energy has been used for thousands of years. The definition for Geothermal is “earth heat” so it is literally the heat naturally created by the earth that humans and other species have discovered to use to their advantage. The earliest known uses are located in china and are based since the 3rd century B.C. although at that time the energy was just…

Biofuels: Ethanol an Alternative Energy Source Abstract In today's society, when someone wants to go to the movies, work, school, library, or mall, they drive to their destination. The average amount of gasoline consumed per year is about 146 gallons in the U.S. (Biofuels for Transportation, p1). Discoveries of huge petroleum deposits kept gasoline cheap for decades and biofuels were forgotten (Leen, p1). However, with the recent oil prices, along with growing concern of global warming caused…

Energy is fundamental item used in making things work. Plants and animals use it to power their bodies and humans use it to power everything else. The problem happens to be the source in which the energy originates. The energy source used right now is burning coal. It is very dirty and it results in massive CO2 emissions. Scientists are looking for alternative energy resources. One of the sources they discovered is nuclear energy. Nuclear energy is “energy stored in the nucleus of an atom” (Office…

the need for energy is growing as well. We are accustomed to using fossil fuels as our central source of energy for everyday uses. Fossil fuels are a natural matter that is found in the ground of the Earth formed in a previous time period millions of years ago that are nonrenewable and are used for energy today. Fossil fuels have to be burned in order to produce energy. When nonrenewable resources have been used, they cannot restock themselves or ever be used again. Renewable energy is a supply…
