Essay about Renewable Energy Systems - 1760 Words

Until the 70’s, renewable energy systems were widely considered minor and declining power sources (Maugh, 1972). Since then, palpable advances in technologies, to produce an array of renewable energy-products (see Pandey, 2009), together with the promise of jobs and higher aggregated value to rural activities (see Domac, Richards, Risovic, 2005), â€Å"greatly contributed to revise this setting† (Cowan, 2002; Petroleum, 2009; Sims, Hastings, Schlamadinger, A. Taylor, Smith, 2006). Change started at a slow but steady pace, led mainly by the successive development of the economies of South-East Asia and Brazil. However, it was only with this decade’s instability and overall rise in fuel prices, amid concerns of climate change (Cox, Betts, C.†¦show more content†¦Moreover, many economic-stimulus bills have been introduced globally with mechanisms supporting investments in Renewable Energy Projects. â€Å"By early 2009, policy targets existed in at least 73 countries from which at least 64 had policies to promote renewable power generation, including 45 countries and 18 states/provinces/territories with feed-in tariffs† (REN21, 2009, p. 8). Accordingly, related RD has been intense and diverse, ranging from the exploration of innovative renewable sources to new types of conversion technologies. Such advances have been accelerating the diffusion of renewable energy systems, reducing costs, and enabling new application scenarios; thus promoting a fast-pacing expansion cycle of the sector. Today there is no shortage of interest and demand for REPs. Since 2004, global annual renewable energy investments have increased 400% to US $120 billion in 2008. While solar photovoltaic capacity augmented sixfold to 16 gigawatts per year, wind-power increased 250%, to 121 gigawatts. Regarding renewable liquid-fuels, ethanol production doubled to an annual capacity of 70 billion liters, while annual biodiesel production jumped from 02 to 12 billion liters. Consequently, there was an increase in total energy production from renewables by 75% during the period, to 280 gigawatts (see REN21, 2009). A recent study by the U.S. Government (Clarke et al., 2007) forecasted that global annualShow MoreRelatedSolar Renewable Energy System1621 Words   |  7 PagesIn brewing industry, 80% of overall final energy consumption is used in the form of thermal energy where solar thermal can be used for brewing processes as below: steam generation, malting process, stopping germination of grains, air cooling, conservation with hot air, power supplying of washing machines, wither and kiln processes.

Simultaneously, many modern building loads and storage systems use rectifiers to convert AC grid electricity to DC for use at the load or battery. Onsite use of renewable energy production therefore requires two energy conversions: DC/AC at the point of generation and AC/DC at the load.

The At The Stones River Battlefield - 1229 Words

On April 19th I recently decided to go to the Stones River Battlefield. In the beginning I honestly was very interested in going to somewhere I had been to before, but then I realized that I could use some new information in my life. I have recently be to the Parthenon in Nashville, and I like it there also, but I am glad that I got the chance to go to the battlefield. However, when it comes to history a part of me find it very hard to retain the information I have learned, and the other half of me see it kind of boring. The more and more I visit places to see and do hands on things for myself, the more it helps me understand what I have learned. With this being said, I am very glad to have attended the battlefield. Amongst my visit, I was a little confused on what I was doing, but I decided to get out of the car and proceed walking to the building. When I entered the building there was a tall guy who greeted me, he wore an outfit similar to a boys scout leader. He then asked me if it was my first time attending and I said yes. There was a couple coming through the door, so he greeted them both and then told us a little about the exhibit. He then instructed us on how to see all of the exhibit and gave us a map/brochure. I then walked away and started to look around on my own. At first what caught my attention is the models and some of the things written on the walls.

Do You Think Mankind Is Born Evil or Good Free Essays

Do you believe that mankind is born good or evil? I believe that mankind are born to be good, but to be taught good or evil as they grow up. It depends on how their life was or how their parents taught and treated them. There is no such as thing being born evil only being born innocent. We will write a custom essay sample on Do You Think Mankind Is Born Evil or Good? or any similar topic only for you Order Now When people are born into this world, they are born innocent and new. Innocence, to me can be seen as good. They are babies, knowing nothing, not even evil . Then they grow and learn and begin to think about behavior. The things they are taught as they are young, and the people they know do much to shape their personalities and awareness. People become aware of what is good or bad partly through experience and mistakes in early stages of childhood development, partly through what they are taught, and partly through their own conscience telling them. If you think back to the first punishment you remember having, do remember why it happened? Do you think what you did was evil? Evil has to do with the heart and mind choices we make in thought and in deed. I believe that we are all born innocent, but are able of giving in to evil, especially in weak moments. Those who continue fighting against that evil, no matter how hard it may be or how many times we may fail, are still fighting the good fight. As I have expressed through my paper, mankind is not born evil, but they are born innocent. Not knowing a thing, good or evil. Evil grows in you as you grow up and make mistakes in your childhood. Trying to fight the bad and attempting to be good is innocent. Most bad or evil choices are made by your conscience. So Mankind is not born evil, but good.
