From the everyday drive to work, to the industrial factories, everything requires energy. With the natural resources depleting, and pollution and global warming increasing, new and better sources of energy is needed. As technology advances, new efficient sources of energy also emerge like fusion, and hydrogen. Older technologies can also be advanced; sources such as solar power, wind, geothermal, and hydropower.
Currently, most of the world is powered by the burning of fossil fuels and other natural resources, but these resources are rapidly being depleted. Although these are very good sources, they emit various types of pollution including greenhouse gasses which cause global warming. Fortunately, more and more newer technologies are beginning to replace the natural fuels.
Transportation is very important today. From cars to airplanes, they all burn fuel. Since the natural fuels are quickly running out, new fuels are invented. Beginning in 1998, many new American automobiles have been built so that they can burn gasohol. Gasohol is a mixture of gasoline and alcohol (mostly methanol or ethanol). Although emissions of carbon dioxide cannot be reduced, many other pollutants are reduced, and gasoline is also conserved. Unfortunately, this fuel is much more expensive, so therefore is not seen readily on markets.
Another alternative fuel that can be used in automobiles is hydrogen. Hydrogen is the most abundant element in the universe, and is relatively easy to obtain. The burning of hydrogen with oxygen will produce no pollutants. The only exhaust is water. In 2002, Toyota released the first hydrogen powered car. The hydrogen is stored under high pressure in vessels made of carbon fiber composites, and then is slowly released into a tank where the pressure is very low. This hydrogen is then moved into the fuel cell, where it is reacted with oxygen. It is the energy created in this reaction that powers the car.
These include: solar energy, wind energy, and hydroelectricity. ... Solar Power, hydroelectricity, and wind energy are all methods of renewable energy sources. ... Solar energy is in essence getting energy from the sun. ... In many cases, wind energy is an ideal power solution. ... Most of the petroleum bi-product is used to produce energy. ...
Energy is a vital part of life. Energy is so important that it makes me think what is the future for energy. ... Wind power and solar energy are two ancient energy sources that have benefited from developments in modern technology. Wind energy is a widely available resource. ... The sun is another means by which we can attain energy. ...
There are two types of energy, Potential Energy and Kinetic Energy. Potential energy is the capacity to do work. Kinetic energy is the total amount of work that is done. ... The producers then use this energy as a form of food. ... ATP is an energy carrier; it transfers some energy to metabolic workers and is formed by aerobic respiration. ...
Energy Supply and Demand Energy supply is the total amount of usable energy available to people for doing work. ... Heat energy is the most commonly used form of energy. Energy may be obtained directly from an energy source, as when people burn wood to produce heat. ... The rapid growth of energy use endangers the world's supply of energy. ... Conserving energy and using it wisely will also make the energy supply last longer. ...
In order for our bodies to gain energy we must digest foods to fuel our bodies. That energy comes from foods and drinks that we consume everyday. ... The law of conservation of energy states that energy is neither created nor destroyed, in order for that to be true for example in eating we wonder where the energy goes. ... The energy that is not used is excreted not destroyed. ... We all use some source of energy and we wonder what happens to it and by the wonders of modern chemistry we can understand apply the law of conservation of energy. ...
Senior Project: How to build an energy efficient house Technology advances on a daily basis. To make these advances the technology needs to be fueled by a form of energy. ... Homes are one of the largest energy consuming units known today. ... Energy prices have been so erratic over the past few years" people are always looking to save money when it comes to energy. I have researched energy efficiency and now I will explain what I have discovered and what I would use to build my energy efficient house. ...
Conservation of Energy Objective: The objective is to find the spring constant, and to find the potential energy of the system. ... The data indicated for the mechanical energy is conserved for this system. ... Another purpose of the lab was to study the effect of conservation of energy. ... Equations for both gravitational and spring potential energy were used. The low percent error between the two values proves that the energy is conserved. ...
The third type is the more efficient use of energy; adjusting to higher energy costs. ... Increased energy efficiency helps the world energy balance and productive conservation is no less an energy alternative than the energy sources. ... Low energy prices make it difficult to convince people to invest in energy efficiency. ... High-energy prices in the 1970s started efficient energy use in constructing buildings and houses. ... Energy is the basis of industrial civilization; without energy, modern life would cease to exist....
