Since the beginning of the time, the most primary method of generating electricity has been through the use of water. Although, now we can even use the sunlight to generate electricity and use it for many other purposes. Due to which solar energy is a major renewable energy source nowadays which actually possess the potential to confront numerous challenges that is being faced through-out the world. The solar energy is and will increase in its popularity. The reason is that it is versatile with…

Title: Solar Energy and All Its Glory Topic: Solar energy has many advantages that make it the best energy source for the U.S. to use primarily. Purpose: The purpose of my speech is to persuade my class to believe that solar power is best energy source for the U.S. I. Introduction A. Attention Getter: Leonardo DiCaprio, an environmental activist and all around beautiful person once said, “ New research shows that by 2050 clean, renewable energy could supply 100% of the world’s energy needs using…

Introduction: Electricity, the base of modern civilization, is produced by electric generators, which are devices converting mechanical energy into electric energy [1-2]. As the need for energy is increasing, while the reserves of fossil fuels are dwindling, renewable energy sources gain importance. The renewable energy can be obtained using solar, geothermal, or wind turbine technologies. Significant research effort has been made in those areas. In recent years, wind energy has become the…

How A Metal Roof Can Save You Money If your home’s asphalt shingles are falling off, blistering, and bending, you need to start thinking about roof replacement. Thankfully, you do not have to use the same roofing material that your home currently has. Metal roofing can actually provide many benefits over asphalt shingles, with several of them being financial related. Here are 4 ways that metal roofing can save you money. You Can Avoid Removing The Existing Roof If the only thing that is bad…

Question /Problem Can a potato be used to build a battery and light up a LED? Hypothesis If I use an electrolyte like a potato juice and two electrodes like galvanized steel and coper, then I should be able to create a small amount of electricity enough to light a LED (light emitting diode). Research Potatoes in general do not generate and do not store electricity. What potatoes do have that can help transfer energy is its soluble chemical property which may cause a chemical reaction…

Standalone Solar Systems - Best Source of Power Supply By monety rackson Jan 25, 2013 Despite energy being the dire need of everyone, there are some corners of the world that still lie shady because of the absence of energy. Fans, air conditioners, bulbs, one cannot think of a life without them. But these things are left meaningless in the absence of energy. Solar systems With time, solar systems have emerged as a solution to the power needs. Whether it is a place where energy does not reach…

1762-IF4 is an Allen Bradley MicroLogix 1200 System with 4 Channel Current/Voltage Analog Input Module. It has a dimension of 90 x 87 x 40.4 mm. It has Delta-Sigma converter and 4 differential (bipolar) inputs. It’s analog operating voltage range is -10 – 10 V DC normal and -10.5 – 10.5 V DC full scale. It’s analog operating current range is 4 – 20 mA normal and -21 – 21 mA full scale. It converts the analog input up to the full-scale range. It enhances the functionality of MicroLogix 1200…

YOUR CHOICE QUESTION: “Site an example of an existing successful plant. Include its location and how long the plant has been in operation. Discuss the life expectancy of the plant and the amount of energy the plant produces.” One very successful solar power plant is the Ivanpah Solar Electric Generating System. The Ivanpah plant produces 392 megawatts of energy, which is enough to power 94,400 homes in America. It is located in Ivanpah, Southern California in the Mojave Desert and was…

P110/120: Energy/Energy & Technology Fall 2015 Homework 05 1. Solar energy can be attractive not only environmentally, but also economically. If an electric clothes dryer has a power rating of 6000 W and is used for 1 hour per day, how much money can be saved in a month by using the "backyard solar clothes dryer" (see Fig. 6.37 in your text), assuming electricity costs 10 cents per kWh? 6000 W x 1hr/day x 30days/month x 1kW/1000 W x $0.10/kWh= $18.00/ month So $18 a month for electric…

photoelectric effect and the nature of light in 1905. Photoelectric effect state that when photons or sunlight strikes to a metal surface flow of electrons will take place. Later photoelectric effect became the basic principle for the technology of photovoltaic power generation. The first PV module was manufactured by Bell laboratories in 1954. Some 5000 years ago, firstly wind power was used to navigate ships in the Nile. The Europeans used it to pump water and grind grains in 1700s and…
