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…

Extended along the western coast of South America sits Chile, a country placed between the world’s deepest ocean, the Pacific, and the longest mountain chain, the Andes. This geographic predicament has left Chile vulnerable to devastating earthquakes due to the tectonic instability of the region. In addition to an unstable natural environment, societal and political instability have also plagued Chile’s past including the incident of a violent coup overthrowing the Marxist government in 1973.…

panels (such as placing them on residential homes) does not take up much land, utility scale commercial solar farms do require a large amount of land. Total land area requirement varies depending on the technology and intensity of solar resources, photovoltaic systems range from 3.5-10 acres per megawatt while concentrated solar power facilities require 4-16.5 acres per megawatt. This large land requirement and the inability to place solar facilities on shared land with agriculture, as is…

2.1. Na-ion Batteries (NIBs) Na-based batteries are not new. Back to the 1970s, Na-ion and Li-ion batteries were investigated in parallel.5,6 The investigation of Na-ion batteries significantly decreased after the success of commercial application of Li-ion batteries in the 1990s. Na-ion batteries have a very similar working principle as the Li-ion batteries. As shown in Figure 2.1, each electrochemical cell is basically composed of a positive electrode, a negative electrode, and a membrane…

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…

Both sources of power have a cost. The largest nuclear power plant in the world is Tokyo Electric Power Co's (TEPCO) or also know as the Kashiwazaki-Kariwa Nuclear Power Plant. The largest solar power farm in the world is the Olmedilla Photovoltaic Park, Spain. Nuclear power and solar power are both a power source. They have many similarities and differences, but solar power is is still a better source. Both Nuclear and Solar are power sources for humans, but solar power is more convenient that…

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…
