...Introduction Renewable energy as defined in the glossary of “Renewable Energy; Myths and Obstacles” is a source of energy that regenerates over a period of time. However, this period of time is significantly shorter than the time it takes for nonrenewable energy sources to regenerate. The most common nonrenewable energy source is fossil fuel. Usually renewable energy depends on the sun’s energy to regenerate; solar energy, wind power and hydropower are examples of renewable energy sources that depend on the sun. Renewable energy, also known as clean energy, is becoming a fast growing phenomenon. President of the United States of America, Barack Obama, mentioned in a recent speech that USA spends nearly one billion dollars a day on purchasing oil from other countries. He also stressed on the fact that air pollution caused by those fossil fuels is becoming one of the biggest worldwide problems. On June 15 in the year 2010, he said, “Now, there are costs associated with this transition. And some believe we can’t afford those costs right now. I say we can’t afford not to change how we produce and use energy— because the long-term costs to our economy, our national security, and our environment are far greater.” Renewable energy is the solution for high-energy demands because it is eco-friendly, economical and inexhaustible amongst many other reasons. However, some might argue that it is not reliable and is inefficient. Ecofriendly Renewable energy is considered environment...

...Why The World Need Nuclear Energy Thermal power stations harness nuclear energy by utilizing the thermal energy released from burning fossil fuels released from the nucleus of atoms through nuclear fission taking place in a nuclear reactor. Nuclear power has enormous advantages regarding the production costs and environmental impacts. Nuclear power is a critical technology of the power production because of the restricted carbon dioxide (CO2) emissions. The entire lifecycle of energy production emits greenhouse gases that are comparable to those of wind energy (Schmidt et al.). The CO2 recommended by the scientific communities such as the Kyoto Protocol is at the maximum of 0.4 billion metric tons that these systems have reached according to the available records (Freedman and Jaggi). For example, in Europe, nuclear plants saves about 0.7 billion metric tons of CO2 emissions annually which is much higher than the Kyoto Protocol requirements (Sada). Also, in the U.S. nuclear power plants saved equivalent amounts of CO2 in 2004. According to the climate change brochure, nuclear energy production saves the world 2 billion metric tons of the greenhouses gases emission to every year that makes about 7 percent of global emissions. Therefore, the world needs to embrace this technology for power production. Track records indicate that nuclear power provides reliable electricity compared to other sources of energy besides clean production. It follows low natural gas prices of accessible...

...l. First main change: The government needs to stop creating long term programs and start to focus on creating more short term programs that are easy to start up A. “I’m also issuing a new goal for America: Let’s cut in half the energy wasted by our homes and businesses over the next 20 years,” Obama said”-Brad Plumer, Washington Post (Pres. Plan to be more energy efficient) 1. The president is definitely thinking about renewable resources and wants to incorporate them into the average American’s life, but again and again he uses words like “hope to”, “proposals”, words implying that these plans are loosely constructed and not in the forefront of the United State’s government’s mind. Maybe this is because his deadline is 20 years away. Obviously long term programs haven’t worked thus far. Making short term projects will make for stricter deadlines, a more focused and motivated team of officials and more projects getting up and running for the near future. 2. We believe that some of the short term programs that should be enacted first are getting the federal government agencies and the White House itself to start using renewable resources. To start having half of the energy these buildings are using to come from renewable energy resources like solar or wind power. By incorporating these types of renewable energy resources into their everyday lives, they will soon encourage the American peoples to use them to, not to mention benefiting the economy. 3.

...P7 describe the three different energy systems and their use in sport activities ATP full name is adenosine triphosphate. It is found in cells and is a type of energy source. Your body’s cells have energy in which is ATP and most of the things that you do are powered by this, for example, such as muscle contraction, protein construction, and transportation of substrates, communication with other cells, activating heat control mechanisms, and dismantling damaged and unused structures. The alactic system uses ATP as the source of energy from the body. The alactic energy system does not need oxygen to function. This energy system is used for physical activity that includes strength, power and speed. For example deadlift and high jump. The alactic I system can give huge bursts of power in very short periods of time. However it only work for twenty seconds or so until the anaerobic lactic and aerobic energy systems take over and start to work. The one hundred metres is a good example because this type of physical activity needs short and fast bursts or energy....

...As to what actions need to be taken to combat terrorism? For starters, we need to take homeland security as a serious matter. The debates around illegals are distracting us from border and port security matters. We need to better manage the funds in rebuilding Iraq because every (billion) dollar saved can be spent on local security and intelligence efforts. Terrorism must be fought both abroad and at home. Next, we must stop fostering terrorism in the world. We may call them insurgents or terrorists, but we need to be mindful that those same people are hailed as heroes, freedom-fighters, and liberators by many in the Middle East and beyond. Every time a stray bomb blows up women and children, every time a soldier murders an innocent villiager, more freedom-fighters/terrorists are created. To rebuild Iraq, we must put the Iraqi-people-building before nation-building. Finally, we must put freedom ahead of any single idealogy, both domestic and abroad. This means that we must implement security measures without taking away individuals' due process under law, we must not allow any government agency to run amok and terrorize our own citizens. Our mission for freedom must be clear to both our soldiers and people of other nations so it does not appear as if we are fighting for oil and profit. Our mission for freedom must be so pure and true so others are willing to fight alongside with us and not against us. The Buddha and the Terrorist Seaman, Donna. The Booklist 102. 22 ...

...one large nucleus or particle, and during this process, energy is released in the form of light and heat An example is in the Sun, hydrogen nuclei fuse (combine) together to make helium nuclei which releases energy. Fission- occurs when the nucleus of one big atom splits into 2 new atoms and a tremendous amount of energy is released in the form of light an heat. (nuclear reactor or interior of the earth, uranium nuclei split apart causing energy to be released) Some of the matter making up the nuclei is converted into energy E= mc^2 Energy = mass X (Speed of light)^2 Indicated that energy intrinsically stored in matter at rest equals its mass times the speed of light squared Suggests that an incredibly huge amount of energy is released when a small amount of matter is converted to energy Radiation Energy radiated or transmitted in the form of rays waves or particles Examples Visible light that can be seen by naked eye Infared radiation Ultraviolet radiation (UV) that cannot be ssen with naked eye Long wave radiation such as tv waves and radio waves Very short waves such as x-rays and gamma rays Electromagnetic radiation --Energy from sun that comes to earth in this form --A type of energy that oscillates side to side and is coupled with electric and magnetic fields that travel freely through space --composed of photons or particles of light which are sometimes referred to as packets of energy -- photons like all particles have properties of waves ...

...along with hydrogen ions from the water to carbon dioxide, reducing it to sugar. Because the electrons increase in potential energy as they move from water(H-O bond) to sugar(C-H bond), this process requires energy—in other words is endergonic. This energy boost is provided by light. In cellular respiration, the summary equation is  Glucose loss electrons and become oxidized, oxygen get electrons and become reduced, so this reaction is redox reaction. In cellular respiration, C-H bond are broken and release energy as the electrons from hydrogen form H-O bonds in water, so this reaction is endergonic. according to the second law of thermodynamics------every energy transfer or transformation increases the entropy of the universe, which also can be understood that during every energy transfer or transformation, some energy becomes unavailable to do work, like heat. we use this equation to show energy transfer or tranformation,ΔG means The change in free energy; ΔH symbolizes the change in the system’s total energy; ΔS is the change in the system’s entropy; and T is the absolute temperature in Kelvin (K) units. When ΔG is negative, mean the reaction can happen spontaneously, release energy; if posivitive, need energy input. autotrophs capture Light energy by photosynthesis, energy transformed from light energy into chemical energy stored in organic molecules like sugar, some is lost as heat when chlorophyll’s electrons go back to its ground state from exited...

...Energy comes in a variety of forms: light, heat, motion, electricity, and so forth. The energy stored in food is measured in units of Calories. A Calorie is defined as the quantity of heat it takes to raise the temperature of 1 kg of water 1°C. (Don’t confuse Calories with calories: 1Calorie = 1000 calories – Tricky!) The energy in food is seen as heat because the energy is released as heat when food is combusted (or burned). Complete combustion results in the production of energy, carbon dioxide and water. Look for evidence of these products during the lab. In this lab, you will measure the amount of energy in calories in two types of nuts: peanuts and almonds. The accepted values for these nuts are 5180 calories/gram for peanuts and 5470 calories/gram for almonds. When you eat nuts, the energy in the nuts is...

...Energy is defined as the capacity to work or the force that helps us to do things with vitality and intensity (Reese, Brandt, and Howie). Having positive energy enables us to make the necessary decisions as far as how we are going to handle unforeseen situations as they present themselves, as well as providing us the “juice” we need in order to perform daunting tasks on a daily basis. Energy can be either positive or negative in terms of how we deal with interpersonal relationships. Positive energy can be achieved through support received from family or colleagues. Negative energy on the other hand can be destructive and divisive which can create havoc in the work place. The authors stated that “it is positive energy that helps us cope with disappointments, uncertainty, and work that is physically and mentally demanding (Reese, Brandt, and Howie). Creating a positive work environment is essential to the success of any business. As the age of adage states “if your employees are happy then your clients will be happy.” Our need for positive reinforcement is critical in how we perform in our daily lives. Few of us have outrageous ego’s to be able to maintain high self-esteem without receiving encouragement or positive feedback from our friends, family, or peers. Without positive experiences in our lives, many people suffer from a deficit of energy. It was interesting to read that in recent years, there have been some researchers who have actually quantified the cost of...

...The Importance of Energy For plant Earth, the Sun is the main source for all energy. It is the main essential thing that provides us with light, warmth and energy. Some organisms, such as plants and algae, create their own food using the sun as their main source of energy. In turn the fuel the rest of the world by creating energy for animals and humans after being consumed. They also remove carbon dioxide from the air and replenish oxygen for us to breath. This process, through which this energy is harnessed and used to create food, or carbohydrates, is called photosynthesis. Can the energy of the sun be harnessed by humans to create energy? It can be and it is through the use of solar cells. Photosynthesis and solar cells are similar, yet different in a few ways. Creating Our Own Energy Humans have figured out how to use the power of the sun for energy. Using Solar panels containing semiconductors, we can turn the sun into electricity, a very popular form of energy. In this way, photosynthesis and solar cells are similar, both using the suns light to create a form of energy. The type of energy created, however, is where one difference comes into play. Plants create a chemical energy known as carbohydrates, a simple organic compound of oxygen, carbon and hydrogen, while solar cells use semiconductors to produce electricity. Use of Electrons Solar Cells and Photosynthesis both use a form of an electron transport system to create their energy. In photosynthesis...

...P3 – Describe the operation and an application of a solar power source. A solar cell also known as photoelectric cell, is a device that alters light energy into electrical energy. One solar cell creates a really small amount of energy (around about 0.6 volts DC) so they are normally placed alongside each other inside an integrated electrical panel known as a solar panel. We are not completely aware of how sunlight is fully converted into electricity and thus we can only convert a small part of the light energy to electrical energy. The current generation of solar cells convert only a small percentage (12 to 15%) of the light energy from the sun into electrical energy which we can use. A solar cell is based upon the “photo-electric effect” which...
