Within the last ten to twenty five years the use of renewable energy resources have become more popular among many individuals. Renewable energy sources made their real entry onto the international energy scene in the 1970s when the two worldwide oil crises occurred. During that time, the prices of oil skyrocketed, thus establishing new ideas and alternatives for energy. In 2010, worldwide renewable energy production reached 66.83 quadrillion BTUs. Renewable energy resources are sources of energy that cannot be depleted. According to the Renewable Energy Working Party (REWP) of the International Energy Agency has set down the following definition: “Renewable Energy is energy that is derived from natural processes that are replenished constantly. …show more content…
This source of energy cannot be used everywhere as it is obvious that not every part of the earth has enough consistent sunlight to sustain energy. This type of energy uses the direct sun to create the energy source. This source of energy helps the environment by generating clean and sustainable electricity without toxic pollution or global warming emissions. It tends to be more affordable. In 2011 a study was done and found that for equipment costs based on dollars per watt of electricity produced, were under $1 per watt …show more content…
These energy sources require us to use what we have without depleting the earth of the resources that it currently has. With these resources being renewable, they are ultimately our future. It is important to try to establish an environment that can adapt to renewable energy resources. Without these sources, environmental degradation is inevitable, it may take thousands of years to come to pass, but it will occur. However, it is very certain that through technology, continual studies, and education, there will be a significant impact on how these resources improve our environment and sustain it as
In this paper, I will write about the history and present use of wind power and the pros and cons of using wind power as an energy source in Vermont.
Alternative energy sources are renewable, and is most commonly referred to as free energy sources. There are many alternative energy sources such as hydro power, solar power, wind, biomass, and geothermal. Using alternative sources is more expensive in the long run, but it is the much safer option for our environment compared to fossil fuels. Although everything used is completely free, such as water and wind, the equipment used to generate these things are expensive. There are several pros and cons that come with the utilization of alternative energy sources.
In developed and developing countries, sustainable energy source is the most important subject. There are many different methods of energy production and consumption. Using the cheap, abundant and clean energy sources for generating the electricity is the basic idea of production. Electrical energy is generated from different kinds of power plants. These plants can be put into three groups; hydroelectric power plants, thermal power plants and nuclear power plants. Hydroelectric power plants are used the potential energy of water. Thermal power plants are used the non-renewable energy sources such as oil, coal and natural gas and the nuclear power plants are used the radioactive elements for generating electricity.
Energy is the ability to do work. It surrounds us in all aspect of life. However, the ability to harness it and use it, as economically as possible, is the challenge before mankind. Alternative energy refers to energy sources, which are not based on the burning of fossil fuels or the splitting of atoms. The renewed interest in this field of study comes from the undesirable effects of pollution both from burning fossil fuels and nuclear waste by products. Fortunately, there are many means of harnessing energy that have less damaging impacts on the environment. One example wind power. Wind energy is a clean and renewable source of electric power and is also the world's fastest growing energy source.
...otection, renewable energy sources are becoming more and more popular between western countries. Renewable energies, such as solar energy, wind energy, hydraulic power are recycle and can replace nuclear energy and fossil fuels to transfer energy to satisfy the needs of electricity. Electricity can bring convenience and efficiency to our daily lives. The lights, transportations, technologies all rely on electrical generation so that the conversion of energy is definitely essential for modern lives.
Wind power is a form of solar energy. Wind is created by unequal heating and cooling of the earth from the solar energy. The energy from the sun heats up the earth causing warmer air to rise. As this occurs, cooler air rushes in to replace the warmer air creating wind. Wind energy can be generated into electricity producing natural power using wind turbines. Wind turbines convert the kinetic energy in the wind into mechanical power which can be converted by a generator into electricity. This energy generated by the wind is considered renewable energy. This means that the source of power is naturally replenished. The renewable energy is natural and continuous in the environment.
What is renewable or clean energy? It is the sustainable provision of energy that will meet the needs of the present without compromising the future generations to meet their energy needs.
Non renewable energy, such as fossil fuel, is used all over the world. Big part of the population assumes that fossil fuel is a reliable source of energy, easy to obtain, and is relatively cheap. On the other hand, fossil fuel is a non renewable energy, which means that we can use it only once. Also, this burning fossils are not good for the environment and are the main reason of the global warming. In this era a lot of new technologies have been invented. Although not every created invention has been for good, renewable sources such as, solar, wind, and human power are a good alternative of energy. Despite some people thinking that solar energy isn’t helpful and it’s only a bad investment; solar energy is the best way to reduce the greenhouse gases and decelerate the global warming, also, is a good investment and it will help you save money in a short term, and unlike the burning fossil fuel, is not harmful for human’s health.
Using renewable energy offer the world a great chance for better change as it doesn’t pollute the environment, infinity &variety sources of energy, secure &save energy needs and lower the cost of energy usage.
With the ever growing increase in population, the demand for energy is increasing every day, and our dependence on non-renewable energy will one day come to an end. Energy is readily available everywhere and can be primarily classified into two principal groups, non-renewable and renewable. Non-renewable energy comes in numerous forms such as coal, oil, natural gas. However, these types of non-renewable energy resources are only available in limited supplies, and once they 're used up, they cannot be replaced. Renewable energy is an alternative to the traditional energy resources that we as a society currently use i.e. oil, coal, and natural gas. Non-renewable energy is also very expensive with regards to retrieving it from the earth and as we all know it causes substantial harm to our environment. Renewable energy or if you prefer green energy are resources that consist of solar, wind, water (hydro), biomass, and geothermal. Furthermore, renewable energy is energy that we do not have to fear about depleting because it is replenished naturally over moderately short periods of time.
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.
In today 's society people use energy in almost everything they do, and this paper is about why renewable energy is better than non-renewable energy. The focus in this article is mostly on fossil fuels as a non-renewable energy source and solar energy, wind energy and hydropower energy. Some important reasons why renewable energy is better than non-renewable is as follows; Non-renewable energy would eventually run out and be in need for new energy sources, some have come to the conclusion that it is cheaper over time and better for the environment to use renewable energy sources considering the global warming.
Solar, wind, and tidal energy is often used in replace of fossil fuels and are most popular because they are renewable. The energy will never run out and can produce a constant energy supply. The energy is also cheaper and more economically sound. The solar, wind, and tidal energy sources are environmentally beneficial because they produce lower carbon levels, does not contribute to the greenhouse effect, and are usually energy saving. However, the alternate energy is not always dependable. It relies upon the weather, and if the required weather isn’t available or produced, there will be no energy made. The energy is also difficult to generate in large quantities. There are not enough facilities, such as wind farms or solar panels, to match up with the developing demand for renewable energy. The large quantities of energy that is produced requires large regions of land for the energy plants to be placed. The plants also have a large capital cost, need to be maintained and require careful planning which is not feasible for many
In chapter thirteen of our book, Environment by Raven and Berg, it shows us just how important renewable energy sources are. Currently the United States of America thrives on the use of fossil fuels and nuclear power. The main problems with these types of fuel are that they are both limited and can be extremely harmful to our environment. They cause global warming, air pollution, acid rain, and oil spills (Environment), and not only that, but in the grand scheme of things, these sources really aren’t even that cheap of a fuel source. There are many alternatives to these all but outdated fuel sources.
Why do we need to rely on renewable sources? Most of the energy that we use today come from fossil fuels such as natural gas, coal, and oil. All of these resources are non-renewable, it can finish one day. In order to have a better world and a healthy environment for the future, people are trying to obtain energy from natural resources instead of non-renewable sources. In the lecture “Renewable energy resources” (2014), Mistry focuses on some advantages and disadvantages of renewable energy. There are different kind of resources that we can use in order to produce renewable energy. Solar power, wind power, hydroelectric power are just some of the kinds of renewable energy that might be the best options to obtain energy because they come from
