Close your eyes, now try to imagine a world with no energy. --- Imagine waking up at about 6 to begin your day. You reach for the light switch and realize it is not working. You scatter around the house for a light source, you even reach for a flashlight. BUT wait no batteries. The only form of light that you will receive comes from that one small candle you are forced to use. You have wasted half your morning looking for light that you must rush to your car. As you begin to drive you realize, "almost empty, better refuel" but the local gas stations display signs that say NO GAS- CLOSED PERMANENTLY. You must abandon your car on the side of the street. It is useless to you now. So you begin to walk to your work which takes you one hour to do. You have now reached your job and once inside you still are forced to wipe the sweat from your face-- you see there is no air-conditioner. AND on your desk hundreds of files that you must sort out replace your computer. You finally end a hard day at work, walk home once more. Hungry, you try to put some food in the microwave but wait you forgot no energy. So you end your day dirty, tired, and hungry, only to go to sleep and do it all again tomorrow. Now you see it would be very difficult to live without energy. Energy is a vital part of life. Energy is so important that it makes me think what is the future for energy.
With an increase in population comes an increase in electric and chemical power consumption. With now over 6 billion people on earth, how will we provide power to the people? The current largest sources of energy are the combustion of coal, oil and natural gas. They will last quite a while but will probably run out or become harmful in tens to hundreds of years. In President Bush's State of the Union address, he called for an energy policy which includes drilling in the Arctic National Wildlife Refuge. WE do not have to succumb to this. It is time to "go out with the old and in with the new".
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. ...
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....
It is the energy created in this reaction that powers the car. ... Geothermal energy is a huge source of energy that is clean and reliable. ... Flowing water has a lot of energy. People over the years have developed ways to harness the kinetic energy and convert it into mechanical energy, then electrical energy. The most common way to harness the energy is by use of a dam. ...
