Recommended: Advantages and disadvantages of solar energy essay

In New Zealand we use various methods for our electricity. Most of our electricity comes from renewable sources such as, hydro energy and wind energy (plus a few more) and the other part comes from fossil fuels. Fossil fuels have some disadvantages to them and photovoltaic panels could possibly be a replacement for them. Photovoltaic panels that use the principle of the photoelectric effect have their own advantages and disadvantages. They require sunlight in which itself is a big advantage and disadvantage. It 's a big advantage because sunlight is free and in most parts of New Zealand there is sunlight however this proves to be a problem because sunlight is limited in the times you can acquire it. The sun is only available during the day …show more content…

As we use AC electricity in New Zealand. It also helps during the summer when people require more cooling down as that 's when they will be longer days therefore maximising the sunlight. One of the good things about using photovoltaic panels for electricity is the fact that it is clean and does not produce any harmful waste products and this is good because this will not just benefit our generation but it won 't put future generations in danger. When we look at fossil fuels they produce air pollution due to the by products of carbon dioxide which add to global warming. Solar power is easy to acquire compared to fossil fuels. To get coal they need to be people that dig up the mines to access it and this is risky because people can get trapped in the mines or hurt in them. As long as better storage batteries or any alternative ways are thought of to store the energy so it can be used other times then Photovoltaic panels are definitely the way to move forward because they have more to offer without putting anyone in danger and not helping increase global

  • Solar Energy In Solar Panels

    Despite generating electricity with fossil fuels for years and years there is a much better way that does not harm the environment. Using Solar panels does not produce any carbon dioxide unlike fossil fuels that “produces huge volumes of carbon dioxide, which is a gas that influences the global climate” (“Solar Power Vs. Fossil Fuels”). Having the choice to get power in a new way that saves the environment, home owners should not have to think twice about trying solar. In fact if home owners collect some amount of watts per hour on Monday, that will not reduce the amount of solar energy a home owner can collect on Wednesday or any other day that week. They can always keep collecting the power. No matter what people may argue about how much coal, natural gas and petroleum remains buried in the Earth, those fossil fuels will run out far earlier than the life of the sun ("Solar Power Vs. Fossil Fuels"). Home owners should invest in solar energy because solar systems have very dependable technology with little maintenance, they offer financial savings and they are better for the environment.

  • Pros And Cons Of Coal

    1412 Words  | 3 Pages

    Today 80% of the energy we use comes from fossil fuels and about 1% comes from solar energy, which is not such a bright idea since nonrenewable resources, such as oil, coal, and gas, are limited (Eia 1). Most significant uses of coal are in steel production, electricity, cement manufacturing, and as a liquid fuel. Solar energy is one of the least used energy sources we have access to in the world; it is also one our mother Earth is relying on to save the nonrenewable fuels, such as fossil fuels. Solar energy is a very useful resource that many of us do not take advantage of because of the limited amount of information we know about it. Cooking coal, also known as metallurgical coal, is used for steel production as well. Coal comes from very

  • Fossil FUels are a Finite Resource

    2385 Words  | 5 Pages

    Many nations count on coal, oil and natural gas to supply most of their energy needs. Fossil fuels are a finite resource. Fossil fuels also causes air, water and soil pollution and produce greenhouse gases that contribute to global warming. Renewable energy from sources that are replenished as fast as they are used. Examples include energy from the sun, wind, moving water and plants. Wind and solar energy are clean sources of energy that have the potential to make a significant contribution to New Zealand economy. New Zealand is rich in renewable energy resources more than developed countries and much of its energy meets by harnessing the power stored in rivers, lakes and geothermal fields. Nearly a third of the total energy is consumed including electricity, heat and transport fuels comes from renewable sources. (http://www.teara.govt.nz/en/wind-and-solar-power/page-1). The 70% share of renewable energy sources make New Zealand one of the lowest carbon dioxide emitting countries in relation to electricity generation. Electricity demand has grown by an average of 2.1% per year since 1974 and 0.6% from 2005-2011. Despite being slightly above the global range New Zealand has called one of the least energy efficient countries when comparing economic output against electricity consumption.

    The reason we don’t replace coal energy is because it produces a profitable amount of energy, just like most cars get fairly good mpg. While solar and wind energy are not efficient and take a ton of sun and wind as well as entire farms of panels or mills to produce the same amount of energy, which goes back to solar and wind being more expensive.

    In our world, many different forms of energy are used to create electricity in order to power a wide variety of things including our homes, cars, and even our handheld devices. One form in particular that interested me is nuclear energy. This form of energy is produced in nuclear power plants and is seen as a cleaner source of energy as it does not produce carbon dioxide or any pollutants that may harm our atmosphere. In a nuclear station, electricity is generated with the usage of heat to create steam and drive turbine generators. However, this energy is not considered a renewable resource since it does produce nuclear waste after all and can be deadly if a power plant was somehow unable to constantly be stabilized and resulted in some sort

  • The Pros and Cons of Renewable Energy

    1524 Words  | 4 Pages

    Global warming is an extremely important and troubling aspect of the world’s current situation. This is due to the fact that the majority of the world’s energy production is from non-renewable energy sources, which are energy sources that either can not be naturally replenished or require thousands of years to be restored. Based on our current energy usage growth rates, there are an estimated 100 years left before our natural resource reserves are exhausted. (Non Renewable Natural Resources: How Much Is Left, Environmental Thinker) China alone consumes nearly as much coal as the combined usage of coal from the rest of the world. (US Energy Information Administration, China Consumes Nearly as Much Coal as the Rest of the World Combined) There is visible evidence of this happening with the increasing pollution levels. Carbon Dioxide and Methane pollution levels in the world reached a record high in 2012 and are 260% higher than the pre-industrial levels. (UN: CO2 Pollution Levels at a Record High, John Heilprin) Converting our world into a more renewable energy dependent society is the most advantageous and likely method for preserving our dwindling fossil fuel supply while also protecting the world that we call home.
