7. Conclusion
How Photovoltaic energy can mitigate climate change:
Photovoltaic electrical energy is the result of the “photoelectric effect”, a phenomena that occurs when metals are exposed to sunlight. The photovoltaic effect results in both a voltage and a current, the two ingredients for electricity’s generation. This is defined as a clean energy mechanism as the source of the energy is the sun and results in electrical energy being generated without the “products of combustion: Carbon Dioxide CO2” as is the case with fossil fuels (coal, gas, oil). It’s ad...

Conclusion:
For years to come there will always be a speculation on whether the climate change has really taken place or not. Many believe that large companies launched this topic in order to benefit from it in profit, as there are also those who are convinced that this are consequences that have emerged from human mistakes in understanding the environment. As humans are struggling to trust one another whether it is just a big conspiracy or not or environment changing itself, we are slowly starting to feel the effects of climate change. Because of the gasses (CO2) that are in the air, atmosphere is getting warmer, thereby triggering the Greenhouse effect. Almost 70% of emitted gasses in air are CO2, which leads us to believe that this is the main cause of Global Warming. Since it is billions and billions of metric tons per year that are being released in air, many scientists conclude that temperature will most likely be more higher in twenty years from now, than it was in near past.
Global warming is a major ecological concern today. It is being caused by man’s ever
For a significant number of years it has been evident that global temperatures were rising and that human activity is a major contributing factor to this rise. The rise in temperature is not only heating the planet but having an adverse effect on the global climate.
Thirty-seven percent of the energy used in the United States comes from oil. Natural gas comes in at second, contributes twenty five percent of the energy. Coal gives us twenty one percent of our energy while the other seventeen percent comes from other energy sources. Those other resources include nuclear, wind, and mostly solar. Besides the environmental harm that some people think fracking has, it has the potential to produce more natural gas and oil. It also is a non-renewable resource and will take a very long time for it to come back because of the earth’s natural creation. Solar and wind power are renewable, but do not produce enough energy to run our country. All of the solar panels and wind mills we have on the earth right now could ...
What are the Causes of Global Warming?
The Earth's climate has changed significantly throughout history. In the last 700,000 years there have been seven cycles of glacial advance and retreat. With the abrupt end of the last ice age approximately 7,000 years ago the beginning of the modern climate era was born. In the last century the global sea level has risen 17cm. All three major global surface temperature reconstructions show that Earth has warmed since 1880. Most of this warming has occurred since the 1970s, with the 20 warmest years, having occurred since 1981 and with all 10 of the warmest years occurring in the past 12 years. There is no denying global warming. Once considered a conspiracy theory by the world’s leading governments, industries and populations; global warming
Global warming and global climate change is the study of future increases of temperature across the globe. Studying climate change refers to how the over- all climate will change such as the dry places getting dryer and the wet places getting wetter. Global climate is dependent on “the greenhouse effect a natural process that helps regulate temperature” (Easterling and Karl). In the past few centuries humans have had a monumental effect on increasing of greenhouse gases in the atmosphere. Climate change is result of the increase amount of the greenhouse gasses in the atmosphere such as methane, carbon dioxide, water vapor, nitrous oxide, and ozone. “Global temperature has rose approximately 1.4 degrees Fahrenheit over
Preview: Today I will discuss the potential that solar power has to become this country’s main supply of energy and the latest research that can make solar power more efficient and cost effective. I will also present the environmental benefits that come with using solar power over other and more harmful forms of energy.
According to Mr. Solar.com, “this type of energy production, known as the Photovoltaic Effect, is achieved by solar panels converting sunlight into energy. Solar panels are made up of several individual solar cells, composed of layers of silicon, phosphorous (which provides the negative charge), and boron (which provides the positive charge). Solar panels absorb the sunlight’s photons and by doing so initiate an electric current, producing electrons. The resulting energy generated from photons striking the surface of the solar panel allows electrons to be knocked out of their atomic orbits and released into an electric field generated by the solar cells, which then pull these free electrons into a DC or directional current.” This electricity then proceeds to a mechanical room beneath our house to a charge controller, which regulates the amount of energy sent to our 24V batteries to be stored.
I am certain that all have heard of the terms greenhouse gases, fossil fuels, and global warming. Have you ever questioned what will happen if nothing is done about the environmental problems facing the world today? What if I answer you that, we can merely use the power from the sun to power up our entire planet without the use of harmful energy sources, which affect our atmosphere? The power from the sun is what we call solar power. Solar power is the energy that comes from the sun as light and heat energy, and then it is later converted into electrical energy through solar panels (Nelson, 2008).
The photovoltaic effect, electricity can be created directly from sunlight. Some semi-conductor materials that are exposed to sunlight can create electron-hole pairs, which can be collected to produce electricity. This occurs when photons have energy above a certain threshold. These photons have shorter wavelengths. In silicon, the threshold for electron-hole production is in the infrared region of the electromagnetic spectrum.
Even though global climate change presents a massive problem, there are many proposed solutions to fix or delay it. These theories range from creating a giant sun shield in space to the simple practice of “reduce, reuse, and recycle” (Gray, 2009). However, the most effective solution is to find different sources of fuel to power our day to day lives. The earth is in need of renewable, effective, and long-lasting fuels. Global warming can be slowed through the use of renewable energy as it is versatile, clean, a good investment, and can easily be put into place in several different climates and environments.
Regarding solar power, Mistry claims that although the solar power does not generate pollution, it has a lot of costs. Building solar panels with photovoltaic equipment has high costs. For instance, a photovoltaic system for a home can cost around $35,000 (Kumar, 2012). However, if our goal for the future is to create a healthy environment, switching fossil fuels for solar power might be the best choice to achieve that goal. According to Kumar (2012), Solar power is a clean and renewable energy so, it decreases the dependency on fossil fuel and also reduces the air pollution.
Using fossil fuels such as coal and oil is inefficient, dangerous, and otherwise a process that is known to eventually fail as a long lasting energy source. Yet, there is hope for the future of energy, this new hope has many shapes and forms, but requires a chance to be fully implemented in our everyday life. Such energy sources like solar energy, wind energy, geothermal energy, and hydro power are the key to our future. These energy sources are proven to be long lasting, safe, more reliable, and the next innovation. In short, all Americans should switch to renewable energy, resulting in a safer and more efficient world.
Scientists blame the greenhouse gas effect in combination with societies greenhouse gas emissions for the rising temperature. The greenhouse effect is a process by which thermal radiation from a planetary surface is absorbed by atmospheric greenhouse gases, and is re-radiated in all directions. Since part of this re-radiation is emitted back towards the earth’s surface and the lower atmosphere, it results in an elevation of the average surface temperature above what it would be in the absence of the gases (Intergovernmental Panel on Climate Change). Simply, global... ... middle of paper ... ... of extreme weather and melting ice caps are indicators of global warming.
