space that the buildings supply. The panels for solar energy can be mounted on a roof structure or on a pole depending on location (Shere 2012). In order for the energy from the panels to be utilized the direct current that is concentrated in the photovoltaic cells needs to be converted into alternating current (Shere 2012). If the facility is not connected to an electrical grid, the alternating current energy can be stored in batteries for future use (Shere 2012). Another thing that needs to be…

Today, 80% of the energy people use come from fossil fuels and about 1% comes from solar energy. This can be seen as not being a very practical use of energy sources since nonrenewable resources are limited. Renewable sources can be replenished and have a much smaller chance of running out than nonrenewable sources. Solar energy is one of the least used energy sources that people have access to in the world; it is also one mother Earth is relying on to save the nonrenewable fuels, such as coal.…

Elizabeth Baker lived thousands of years ago, during the Middle Ages. She lived in a cottage with her entire family. They were bakers who went to church every Sunday and lived very religious lifestyles. When they were not walking to and from church, however, they were doing chores because they had no electricity to light their house at night. Elizabeth lived without electricity and air conditioning. Today we are fortunate to have these privileges but what would happen if the world ran out of…

The Impact of Wind and Solar Variability in Grid Network 1. Introduction The renewable energy development has accelerated over the last decades. Renewable energy can benefit in such a way in various point of view. In an economic perspective, this type of energy has been more economically accepted in the market due to the decline production cost and no requirement of fuel and hence is relatively safe from fluctuated fuel price risk. Moreover, this type of energy can be found in many locations in…

need to be reviewed. The input and output parameters should be defined so that there is regular flow of energy can be generated and supplied to the sources (Dale, 2013). The maximum performance can be enabled at 28.8 volts through deploying 72 photovoltaic cells at one of the tower. The output should be in form of direct voltage at 48V, 24V and 12V values. The carbon footprint can also be tracked in form of CO2 emission that can be reduced through using solar energy (Fanni, Virtuani, Chianese,…

Climate change and pollution are serious global issues. Recently, cities such as New Delhi and Beijing have been plagued by unprecedented levels of smog, leading to riots and unrest. Greenhouse gases have greatly increased the temperature of our atmosphere and are upsetting the Earth’s fragile balance as an ecosystem. Consequently, in 2016, the arctic ice sheet was the smallest ever recorded, but most worryingly, according to NASA, the past 13 years have had the 13 smallest ice sheets on record…

In its most elementary form, a solar photovoltaic (PV) cell converts solar energy (photons) into electricity (voltage). A solar PV cell is comprised of two doped layers of semiconductor material and generates low-level voltage (less than 1 V). A solar PV module refers to a series of solar PV cells connected together (to generate higher voltage) and laminated into a durable package. A solar panel is formed from the interconnection of several solar PV modules. Finally, a solar PV system is made…

The word “photovoltaic” combines two terms – “photo” means light and “voltaic” means voltage. A photovoltaic system in this discussion uses photovoltaic cells to directly convert sunlight into electricity. A photovoltaic (PV), or solar electric system, is made up of several photovoltaic solar cells. An individual PV cell is usually small, typically producing about 1 or 2 watts of power. To boost the power output of PV cells, they are connected together to form larger units called modules.…

As a result of the global high intensity industrial development, increasing amount of energy consumption is required. Hence this has lead to a situation in rapid depletion of fossil fuels such as oil, coal and natural gas; furthermore the negative effect caused by the greenhouse gas produced when burning fossil fuels must be considered. In order to protect the environment together with maintaining enough amount of energy needed in the future, the world have to depend more on producing renewable…

Jack O’Keefe Ramsdem, Stephen W. "Total Eclipse of the Sun." Sky Watch (1089-4888), Jan. 2017, p. 48. EBSCOhost, With less than a year left, America is getting closer to its solar eclipse. This major event should be happening on August 21st 2017. The solar eclipse will be a one time thing for some people in their lives and they would ever want to have to miss a once in a lifetime opportunity. With social media and just the media in general, this event will be one of the most popular phenomenons…
