How can energy be converted from one form to another? All forms of energy can be converted to another form of. For example: A pendulum is an object is suspended by a string or wire for support. If the object is moved to one side and then released, it will swing back and forth in an arc. At that moment the object reaches the top of its swing, it stops for an instant, and then begins another swing. At that instant of stopping, the object has 100 percent potential energy and no kinetic energy. The object starts back down through the swing, the object is gaining kinetic energy and losing potential energy. At the instant the object is at the bottom of the swing, it has 100 percent kinetic energy and no potential energy. As the object climbs …show more content…
The Biomass energy is an organic matter that is used by photosynthesis. This is used to generate energy and the most common energy is coming from the wood of the trees, corn, municipal solid waste, and sugarcane. The biomass is used to create ethanol, biodiesel, bio oil and biogas. This in turns create electricity with steam turbines and gasifies to produce heat. The advantage of using the biomass over the fossil fuel is that biomass is a renewable carbon source, zero net carbon dioxide emissions, lower methane, sulfate, and hydrocarbon emissions, and the most important is no dependence on foreign oil. Another is the geothermal energy, in which it uses the heat from the earth to warm things up. The common source is cost effective, reliable, and environmentally friendly. The main sources of uses are to heat homes, greenhouse, industrial process heating mineral recovery, fisheries and also mitigate global warnings. Geothermal energy is more valuable than the fossil fuels because it is an inexhaustible energy source, lot less emissions in the atmosphere, more efficient than solar energy, work under any kinds of weather conditions. The fossil fuels are irreplaceable, create massive environmental pollution and are also causes the major factor of the global warming and the ozone layer depletion. Also the Biomass and the Geothermal are very inexpensive compare to the fossil fuels by almost 50 percent.

The book I am reading is called The Cellar, written by Natasha Preston. The main character in this book is a 16 year old girl named Summer. Summer lives in a small town with her mom, dad and brother, Henry. One evening Summer wanted to meet some friends at a club to hang out and have fun. The club is only a two minute walk from her house through the woods and she had done it many times. She left the house in a rush, quickly saying goodbye to her parents and boyfriend, Lewis. Never once thinking about the dangers of walking outside alone at night.
One of many possible renewable sources of energy is biomass. Biomass energy is the power that is contained within plant and animals.
Biomass is the use of organic matter to make electricity. Organic matter such as trees and plants are burned and heat water to create steam. The steam created from boiling water is used to turn turbines to create electricity. Biomass can also be used to create Methane which is used to create even more electricity.
Novelist, Nathaniel Hawthorne, in his fictional novel, “The Scarlet Letter”, expresses a story about a young woman, Hester Prynne, back in the 1600s who was convicted of adultery and must now wear a big “A” on her chest to show those in the small Massachusetts Bay colony the sin she has committed. Hawthorne’s purpose is to illustrate the hardships Hester must go through for committing such act in the small colony where religion was put first. Hawthorne adopts a serious and pitiful tone throughout the novel to get the adult readers to sympathize with the main character, Hester Prynne. Though this book was written back in the 1800s and is based off a woman who’s shamed for adultery, this book can still relate to today’s world with some of
In this day and age, finding an alternate source of energy to fossil fuel is essential. Humans are using up fossil fuels, such as coal and oil, faster than they can be made naturally.This means that there will be a time when all of the fossil fuels will have been used to power . To prevent a world without energy, many alternative sources have been harnessed. Six different pathways for energies were found: solar power, biomass, geothermal power, hydropower, wind power, and nuclear power. All of these are much better alternatives to fossil fuels, as they reduce carbon emissions. Carbon dioxide is one of the greenhouse gasses in Earth’s atmosphere, which when created in excess, causes things such as global warming to occur. But when they are compared to each other, some seem better than others in many different ways. Although wind and hydropower are both promising alternative energies, wind power would be better for New Jersey, because it is space efficient, relatively cheap, and the turbines can be placed almost anywhere.
Abstract – The world can’t be imagined without IC Engines ,as their applications are wider in various fields. And mainly used input for this engines are fossil fuels. But the challenge in this is decreasing rate of resources. The fossil fuels may not be available after some years if they used in the same way .Not only the fossil but also the electric power is the non renewable energy, This paper concentrates to run the engine without fossil fuels or electricity.
“86% of the energy the USA uses comes from fossil fuels like petroleum and coal that provide electricity and gas to power our growing energy needs.” Fossil fuels are a non-renewable source of energy, meaning that we will eventually run out one day in the near future. When we drive our cars to work, taking long showers, and leaving the lights on, we usually don’t realize how much of our resources we are using. Fossil Fuels, Power Plants and Fracking cause many of our environmental problems that the world faces today due to our growing dependence on energy. These environmental problems include global warming, air quality deterioration, oil spills, and acid rain. Saving and producing energy from a renewable resource such as sunlight not only helps to conserve our limited resources but also translates into happiness, safety for our environment, boundless energy, and a personal benefit, such as financial savings. During the 18th century, massive quantities of fossil fuels were used to power the economy let alone the world. MHI states that “During the Industrial Revolution, fossil fuels seemed to be the ideal energy source because of its seemingly endless supply. Many machines during the Industrial Revolution such as the Steam locomotives, used coal as a form of energy which would fuel the machine early on to balance the lack of firewood and charcoal.” In this article about fossil fuels, it states that we continued to use coal because there was a seemingly endless supply of coal
As we increasingly realize that our own self-destruction is inevitable in the destruction of the planet, the insular notion of Western modernity as the height of human progress is \ finally being questioned. However, the resultant paradox is that although we realize the resultant flaws of depending on one form of progress, the only alternatives that we could turn to are dying off of the face of the earth. Thus the global trend of language loss is an issue incredibly worthy of long overdue attention; it may in fact be our last meaningful alternative to rescue the plight of humanity’s survival. As a repository of knowledge, an expression of culture, and a symbolic embodiment of a way of life, the loss of a language speaks for itself.
Biomass is an organic matter that comes from plants and also from animals and it is also a renewable energy source. Biomass can also be used as a facility heating, Electric power generation, and combined heat and power. Using Biomass is Burning, Fermentation, and Conversion. Reason why Biomass is a renewable source cause supplies aren’t limited. And biomass reduce dependence on foreign oil cause biofuels is the only renewable liquid.
Aviation industry has been booming over the couple of years. This would mean that the usage of
The world is constantly changing, power sources also come and go. But there has been one energy source that has dominated the world for a long time, fossil fuels. Fossil fuels are an energy source that includes coal, natural gas, and oil. Fossil fuels have been used for a long time because of their energy output. The downside is that is very harmful to the environment, so that is why we have renewable sources that are eco-friendly. Renewable energies still have not won the favor of the crowd because fossil fuel use is still much higher than renewable energy. The topics that will be talked about is the problem of fossil fuels, advantages and disadvantages of renewable resources, and an innovative solution.
Our society today thrives off of energy consumption in order to carry out daily activities. Since the second and third centuries people have been using fossil fuel for heat and energy. In the 1700s, the use for coal really took off when it was found out that it could be used as a source of energy to create the energy needed to drive locomotives. As each new invention that needed power came into existence since the 1700s, fossil fuels became the energy source that was chosen and because of this our society has become dependent on fossil fuels for energy (United States Department of Energy, 2013). Today fossil fuels are still in high demand.
There has been a growing pressure to develop alternative energy production paths to reduce the dependency on fossil fuels, while at the same time reducing CO2 emissions to prevent global warming. Energy from the waste conversion is considered as alternative mean to create renewable energy. Besides its importance in power generation, char as one of the pyrolysis product is considered as a potential source that can be valorised alongside oil and gas (or syngas).
Renewable energy is the best alternative for fossil fuel because of the minimum pollution impact, endless characteristic, there are too many type of renewable energy technologies which will be used in different places with different climate, it is depends on technical characteristics, resources availability, economic factors
If America makes the change to renewable fuels, it could take hundreds of years to undo the indirect damage that will be triggered. The amount of pollution that would be emitted by harvesting new fuels is as devastating as not switching at all (Grunwald). The processes for acquiring these alternatives create pollution that will destroy our environment. It is counterproductive to use renewable energy, if it does not enhance the current situation. Many people are supportive of the change, but are unaware of the long term effects on the economy and environment. The issue of alternative fuels is a controversial topic around the world with numerous countries wanting to use a cleaner fuel source than petroleum and
