The term “renewable” in the context of energy sources means that it can be utilized without depleting or weakening the supply. In other words, the earth creates that resource at a rate faster than we can consume, therefore, we can use it without affecting the atmosphere and other natural resources. Numerous forms of renewable energy that have been discovered and are now utilized, the two types I have decided to extensively research and focus my post on are wind power and geothermal energy.
Although fossil fuels are the main source of energy on Earth, there are several other forms of energy that are gaining in popularity. Alternative energy, or renewable energy, is a more environmentally and economically friendly source of energy. There are four main forms of alternative energy; solar, wind, nuclear, and hydroelectric. Each source has several different advantages over fossil fuels as well as disadvantages of use and durability. Using these renewable sources as the main provider of energy is starting to become more realistic than relying on fossil fuels. Although it may cost more to construct the technology for these sources, in the long run, they end up saving the consumer more money than fossil fuels do. These sources are starting to become more and more used throughout the planet and pretty soon, they may be the only source of energy that people have.
Renewable energy is energy from a source that is not depleted when it is used.
Renewables are better environmentally than any other power source under specific circumstances. The two most touted renewable energy sources are wind power and solar power. The specific circumstances in which they are better are when the wind is blowing and the sun is shining. Unfortunately, neither the wind nor the sun can be guaranteed to function for any specific date or time. The sun can only be guaranteed not to shine for approximately twelve hours a day and wind has no guarantees at all. Also, technology is not advanced enough to adequately harness the power provided by the sun and wind when they are available. It would take five hundred times the amount of land to build a solar plant with the same output as a nuclear plant (Oliver Hospers 24-25).
Renewable energy may seem like a daunting task, but the benefits to humanity could be incredible. Public uses of renewable energy range from transportation all the way to heating and cooling. Everything we use could become less explosive and less expensive. Cities with a high concentration of people could become safer and healthier places to live. Transportation could be converted to electricity dramatically, improving smog conditions. Global warming may or may not
Renewable energy is considered an environmental friendly way of producing energy; according to http://www.renewableenergyworld.com/index/tech.html, “in contrast, the many types of renewable energy resources-such as wind and solar energy-are constantly replenished and will never
Unlike coal powered electric plants that produce abundant supply of power, renewable sources can’t produce that much of energy in short span of time. The technology that is used in producing energy is new and major other factors like weather play spoilsport that hamper the production of energy on large scale. This simply means that either we have to reduce our energy consumption or set up new facilities that could produce energy at a faster rate.
Renewable energy is an extremely popular topic in conversation, politics, and media. Consumers are interested because it raises real estate value, cuts power bills, and offers a tax break on homes equipped with solar panels. Environmentalists agree with renewable energy because it produces little or no waste products such as carbon dioxide and other chemical
Renewable energy sources are good for the environment but some people frown upon the idea of having renewable energy sources. They are more expensive than fossil fuels and nonrenewable energy sources. A Lot of energy needs to be put in both the research and manufacturing of nonrenewable resources. Renewable energy sources are cheaper because of the energy source already having the components in order
Green energy is just another term to describe any sort alternative energy that is produced with less negative impact on the environment. Renewable energy is green energy generated from natural resources such as sunlight, wind,
A renewable energy source is a source of energy that can be renewed or replaced like solar or wind energy, these are examples of renewable energy sources because they can be replaced. Solar energy, the sun will never run out (until billions of years later) and wind energy is renewable because we can’t run out of wind. Now, non-renewable energy. Coal, oil, gas these are all examples of non-renewable energy sources. They are non-renewable energy sources because once you use it, you cannot replace it. So renewable energy is energy that can be replaced and non-renewable energy is energy that cannot be replaced.
“Renewable resources have a high development cost it costs lots of money to develop there stations in research and manufacturing the components needs so that they become successful.” Which is stated in the article of pros and cons of renewable resources. Renewable resources also do not produce in large quantities, so if we were to use renewable resources for energy we would have to reduce our energy consumption. Renewable resources are also vulnerable, almost all of the renewable resources are vulnerable to weather such as rain, snow, and cloudy days.
Wind energy is a renewable energy resource that is natural occurring with unlimited supply. The energy generated from wind is clean with little impact on wildlife and the environment. Technology such as wind turbines are used to capture the energy from wind. Compared to Solar energy, another renewable resource that uses the suns heat as energy, wind energy is less efficient. The amount of power collected from solar panels exceeds what is collected from turbines. Although solar energy are more efficient, it comes at a cost. Solar technologies are more expensive than wind turbines and
Renewable energies have satisfactory EROEIs and they aren’t subject to depletion unlike non-renewable and nuclear energy sources. However renewable energy sources are far from producing enough energy to fulfil the world’s needs.
Renewable Energy is defined as: a renewable natural resource or source of energy, such as water, wind, or solar power (Oxford English Dictionary). There are those that believe that our nation should abandon the use of fossil fuels such as oil, natural gas, and coal, and switch to renewable energy sources. Although the change could yield many benefits, I believe that renewable energy is a not viable alternative for our nation’s energy future because it would create an unfavorable environmental impact, it is not as reliable, and it would be too costly.
