Energy Of Renewable Energy Sources Essay

Everyone uses a lot of power for lighting, heating, machines, movements, and so much more. All of that energy has to come from an energy supply. Some energy resources are renewable, while others are non-renewable. Energy has various forms and is a very essential part of our everyday lives.

When the new Southeast Polk High School opened they added many new energy saving products. This included installing geothermal heating under the high school cutting back on the cost of heating such a large building. Many new windows help save on energy used to light the building along with automatic lights that turn off after several minutes without movement. The new high school shows how easy it is to save money and help the environment. Renewable energy is good for all aspects of the U.S, providing jobs, economical growth, environmental cleanliness, and new research for improving energy efficiency. Therefore the United States should use renewable energy to benefit the economy and environment.

Energy is crucial to almost every major and opportunity the world faces today. From the perception of jobs, security, climate change, food production or increasing incomes, access to sustainable energy for all is essential for strengthening economies, protecting ecosystems and achieving equity.

What would happen to our world if our energy unexpectedly disappeared? Fossil fuels are very important to our world because they provide an overwhelming majority of our world energy. So, what happens when they run out? This research paper confronts this question with a balanced view attempting to address the issue of what sources might provide energy in the future and come to an objective conclusion. As the world enters a new century, new sources of energy such as wind, solar, and hydrogen power need to be developed to help the world keep running on all cylinders. With the development of these new energy sources, our world would become a cleaner place and the energy crisis would straighten itself out.

Energy is a big part of our lives. We are heating our homes with natural gas or electricity and driving to and from work and any other outdoors activities. Our main source of the energy people use is fossil fuels and in the future, the availability of those sources has an end date. As studies show there are renewable resources of fuel and other equipment used for energy like wind, nuclear power plants and solar hydroelectric. There are many pros and cons to all forms of energy source, and they all have their own merit. Also, the energy sources that people use does have floss and can cause a negative impact on the environment, and humans. The most important goal is reducing the overall use of our energy sources.

Bilen et al., (2008:1531) predicted that global energy consumption will account for around 85% of the increase in world primary demand over 2002– 2030. The increasing of global energy demand happens the global stock of fossil fuel resources may be adequate for short term period, thus requiring the development of renewable energy sources, which would not decrease the stock of fossil fuel resources available for future generation. There is an increasing interest in the development of renewable energies such as biofuel and wind power, which have a great potential energy to produce enough power for the world’s population demand.

Target 7.1: Dimensions can be created to track the progress of this target however, they are difficult to quantify. This is due to the fact that the metrics which can be created to measure this target depend on what the key elements of the target (such as universal, affordable, reliable, and modern) are agreed to be defined as. What is considered to be affordable/reliable/modern can be subjective especially in a global context. Therefore, the dimensions can be measured, however the target itself is not truly measurable.

“As a source of energy, nothing matches the sun…. Only a small fraction of the sun’s power output strikes the Earth, but even that provides 10,000 times as much as all the commercial energy that humans use on the planet” ("Make Solar Energy Economical"). This is good evidence that investing in solar energy can be valuable because not only is it clean and renewable, but it is also plentiful. This makes solar energy better option then the use of fossil fuel, however there are a couple of challenges with solar energy that must first be overcome before even thinking about cutting fossil fuels. For example, while solar panels do create energy from the sun, they are not very efficient. Most of today’s “commercial panels” only capture 10 to 20 percent or the sun’s energy which means the cost of solar energy is 3 to 6 times more expensive then what we currently use (qtd. in DOE). Additionally, the the solar panels can be costly to manufacture because the materials used need to be of high purity so it does not interfere with the flow of the electrical charge. One also needs to consider that while the solar panels can create energy when the sun is out, this is not the case during the night or when it is cloudy/stormy. Therefore, storage of this power is very important because it would enable people to always have power. So, solar energy is quite promising and with improvement it has the ability to replace fossil fuels which is one of the grand challenges for engineers.

A key solution to the energy storage and wastage problems is offered by renewable energy sources; however, their integration with the existing grids comes with a set of barriers such as the intermittency of generation and the high level of distribution of the sources and the lack of proven distribution control algorithms to manage such a highly distributed generation base [2]. In such situation, the use of communication and information technologies is attractive to match the demand to the available supply and dramatically improve performance and efficiency. A smart grid is an intelligent electricity network that integrates the actions of all users connected to it and makes use of advanced information, control, and communications technologies to save energy, reduce cost and

Sustainability: It has become increasingly important to innovate in the production, delivery, and consumption of water and energy. Improving access to these precious natural resources through responsible conservation and effective management, as well as embracing a culture of sustainability, are important goals of all countries. “Smart Grids” have presented an opportunity to revolutionize the way energy is both produced and consumed as a result of the convergence of IT in both existing and new infrastructure (e.g. solar panels) to deliver

Energy is a crucial necessity and with the ever increasing need for it and the high and fluctuating prices of oil, researchers are constantly coming up with newer and more sophisticated alternative sources of energy. However, energy comes at a cost, as it is either expensive or it possesses high health risks. This essay presents the concept of energy by discussing the two major types of energy, the various forms it could take, including renewable sources of energy, energy conservation and above all it talks about the safest and cleanest alternatives.

The aim of this paper is to replace traditional components like diesel generators which are used to generate power in a microgrid with renewable energy sources for an Air-force field deployable hospital (AFFDH). In this paper we assume that Air-force field deployable hospital consumes approximately 70KVA of peak power. ETAP software is used to operate for island and grid connected mode and also load flow and short circuit analysis are performed on the system for variety of load and fault scenarios.

Our world and specifically the U.S. are dependent on the use of fossil fuels. Fossil fuels are a nonrenewable resource and one that we are extremely dependent on. We will soon run out of fossil fuels, and when that happens in the near future we must be prepared. There are groups that believe that renewable energy is not efficient, and the cost is too great to be effective. Some even believe that jobs will be lost and the economy will falter. There is some truth to this, but this argument is much deeper than monetary issues. In the long run, it is essential to develop renewable and clean energy sources because without it the U.S. may very well be doomed. It is also beneficial to develop alternative energy they have many advantages over conventional fossil fuels. A complete effort is essential in order to successfully transfer to clean and renewable energy. These energy sources have major benefits for the U.S. who is far behind European nations, and without improvements will fall behind. Developing clean and renewable energy results in multifaceted benefits; these benefits along with the fact that we have a limited supply of fossil fuels allows for the conclusion that it is vital to commit to renewable energy.

Modern alternative energy generation methods are limited by several factors including efficiency, inability to respond to sudden changes in power demand, and susceptibility to environmental events. In 2010 the leading renewable energy sources were hydro-electric, wind, bioenergy, geothermal, and solar Photo Voltaic (PV)[1]. Of these, hydroelectric made up 82% of the renewable resource energy generation, while the other means all contributed about equally. These relationships can be seen clearly in the table below. Although hydroelectric makes up a large portion of the electricity produced, it is not appropriate to discount the other sources due to the frequency where hydroelectric power generation is unpractical. It is important to have a
