What Is A Renewable Energy?

In recent years there has been great concern over the growing demand for energy, and the lack of non-renewable energy resources to meet the demand in the future. In addition, the question of “sustainability”—the ability to balance social, economic, and environmental needs in energy production to meet both current and long-term requirements—has come to the fore. It is clear that America must expand energy production quickly, and that we must develop renewable, sustainable energy sources to meet long-term demand and protect our future. There are many proposed solutions, such as wind and solar power. But the technology for these resources is not yet fully developed, making them, at best, low-output alternatives. Because renewable sources are

With the rise of nonrenewable fuels prices and the estimated decline of availability in the not so distant future it is very clear that the only answer to this problem is to implement the use of renewable resources. Renewable resources are very versatile and can reduce pollution of the environment and can in the long

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.

In 21st century almost all devices work with electricity. Electricity makes activity of people easier and more comfortable. Moreover, it plays a great role in development of medicine, science, education, transport and other spheres of human’s life. However, electricity production is becoming more and more problematic because the biggest part of energy for electricity is produced by natural resources, which are neither infinite nor renewable. It means that one day mineral reserves can run out, and, as a result, there will be risk of possible energy crisis. This situation stimulates humanity to transfer to renewable power system. Countries around the world are promoting sustainable energy policies, particularly to reduce

In this day and age, we have new energy sources that could be used to power our homes and transportation. Wind and solar power are used all over the world, but are still used far less than fossil fuels. Most would say it’s not reliable or it doesn’t make any profit. While both statements are true, it doesn’t mean we can’t make a better future using renewable energy. In fact, the only reason we don’t use renewables for everything is that we don’t want to change. The hard truth is we need to change. Fossil fuels are great right now, but if we run out, humanity must have another source of energy.

Nowadays everyone has heard about climate change, global warming, and greenhouse effects. We hear it from the news, social media, scholars; climate change is coming and it is going to destroy Planet Earth. For decades, scientists have been trying to reduce toxic emissions that cause climate change. The quest of new forms of energy has been long and intense but lucky scientists have found the answer: Renewable Energy. As best explained by Pennsylvania State University Extension, “Renewable energy is energy that is generated from natural processes that are continually replenished.” Although many are still hesitant to switch to renewable energy there are countless benefits that come along with the environmental friendly energy source. These kinds of energy are produced and generated from natural resources such as wind, sunlight, water and geothermal heat. There are incredible benefits about renewable energy one of them is that it can be constantly renewed. In addition, renewable energy is much more reliable and efficient than non renewable energy. Lastly, renewable energy has almost has no negative impact on our environment and thus helping to conserve and protect our home; Planet Earth.

World population growth results increase in energy demand, together with growing global consciousness about the scarcity of the earth’s natural resources, has turned the attention of researchers into alternative renewable energy sources. Traditional energy sources are characterized as exhaustible and some of them, especially fossil fuels, have substantial impacts on the natural environment and are the main culprit of climate change. As a global solution, renewable energies play a key and unique role, since they are obtained from natural, regenerative sources that do not deplete; and they also cause minimal to no environmental problems, such as climate change, radioactive waste, acid rain and air pollution. The sources of renewable energy that have reached full commercial maturity are: solar, wind, tides and waves, rivers, geothermal energy, organic waste and energy stored biomass (Okure et al, 2006).

Bilen et al., (2008:1531) predicted that global energy consumption will account for around 85% of the increase in world primary demand over 2002– 2030. The increasing of global energy demand happens the global stock of fossil fuel resources may be adequate for short term period, thus requiring the development of renewable energy sources, which would not decrease the stock of fossil fuel resources available for future generation. There is an increasing interest in the development of renewable energies such as biofuel and wind power, which have a great potential energy to produce enough power for the world’s population demand.

Reducing the carbon footprint or lessening the human impact on the earth has only become increasingly popular as societies are now striving towards environmental sustainability. One of the major drivers towards sustainability is to reduce the global dependency on non-renewable resources such as coal, oil, and natural gases. At the current rate in which the world population is expanding, along with the progressively quicker depletion of the world’s non-renewable energy resources, the current energy situation is not sustainable for future generations. There are practices in place to promote alternative renewable energy sources sector such as wind, solar, or tidal power to ensure sustainability. However, in ensuring the global

The renewable sources of energy listed above have some advantages. They are naturally occurring and thus do not require much effort to harness. Besides, they are natural components of the environment whose use does not contribute to environmental pollution (Tiwari et al., 2012). The fact that they are never depleted also guarantees users who have installed the necessary harnessing machinery, of a continuous supply of energy. Despite these advantages, however, there also exist some demerits. Much as these sources are

Alternate energies are forms of energy that do not deplete natural resources or harm the earth. The sources of the energies are naturally found or generated or are part of a natural conversion from one source into another. Energy cannot be destroyed but can be converted into other forms, therefore there are many reactions occurring around us that allow us to harness these energies. Alternate sources of energy has been extensively researched as a result of the large energy crisis that is being experienced globally. The global demand for energy is becoming higher than the amount of energy being generated (Bilgin). The global economic equilibrium is unbalanced leading to energy based market failures and poor policies for energy generation which is leading to more problems than it is solving. Another reason for this research are studies regarding global warming. Currently, the energy sector is predominantly made up by fossil fuels which are incredibly harmful to the earth and nonrenewable. Cleaner, renewable sources of energy are being sought in an attempt to reduce emission of greenhouse gases from fossil fuels and to help regain balance in the global energy market. Some of these forms of energy are solar, wind, biomass, and hydroelectric.

Renewable energy’s definition is “Energy from a source that is not depleted when it is used” (“Renewable Energy – Definition”) and it is present throughout the world in a variety of countries. Given the variety of sources and the complexity of each, many other countries vie to stay with cheap, affordable, unhealthy non-renewable fuels such as natural gas, coal, and oil. This paper looks to review the production and consumption of energy – both renewable and non-renewable – over the history of renewable energy, then analyze why certain patterns may appear. The first step in this process is to define each type of renewable energy so that they can relate to each country that uses these sources.

In the past decades, there has been an important argument regarding energy and its sources. Energy resources are classified into two groups: renewable and non-renewable. Although renewable sources have not yet been exploited to their maximum, their use has been increasing since the 1960’s. The main renewable energy sources are Wind, Geothermal, and Solar energy. Contrary to renewable sources, non-renewable sources lead in the production of electricity and other forms of energy. For non-renewable sources, Fossil fuel and Coal are the main producers of energy in many parts of the world, followed by the Nuclear energy that has increased in its used and production in the past decades. Solar and nuclear energy are possible suitors in the task

In today’s world of scarce resources energy efficiency and renewable energy become increasingly important. It is also well-known that the climate-change as a result of high CO2-emissions, among others, can only be stopped or at least slowed down by reducing these emissions. The general global trend therefore should move towards an increasing use of renewable energies while gradually stopping dependence on non-renewable energies, such as coal or oil. Despite trade-offs in terms of a possible rise in energy prices and impacts on security of energy supply, most developed countries have recognized the general need of a change. (Röpke, 2013)
