Energy is the most outstanding ingredient for socio-economic growth world-wide. It exists in various forms like mechanical, chemical, electrical, heat, light etc. There is minimum amount of energy required for life sustainability. Most especially from the food we eat but fuel energy is needed in cooking and in some climate, for heating houses. Research has shown that in 2008 for instance, the world wide consumption rate of energy was estimated at 500 exajoules per year (EJ)/y. The importance of an energy system is to secure energy service in the industrial, transport, house hold and service sectors of the economy. Energy, invariably is the fulcrum of growth of national economies. Fossil fuels are carriers of hydrocarbon substances. They include coal, crude oil, and natural gas. Its consumption depletes at any rate. Typically, the looming energy crisis is sequel to consuming these fossil fuels at a rate that is practically unsustainable. Besides, when consumed, fossil fuels upset the natural balance of carbon dioxide in the atmosphere, giving rise to various environmental tipping point. Effects of this carbon dioxide natural imbalance has its long term contribution to global warming and green house effect. Conversely, renewable energy systems are resources available on cyclic basis and include solar, hydro, wind, tidal, wave, geothermal and biodegradable biomass (fuelwood, animal and crop residues, energy crops etc). They do not deplete on consumption. The application of
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
From the time when man invented fire, he has put his faith in one energy source or another. Energy plays a significant factor in our lives, providing luxury, swelling productivity and letting us to live the way we want too. Our lives are exactly surrounded by energy, but we do not habitually stop to think about why those energy sources are significant. Energy is the most discussed subject and has become a basic requirement for the societies. It is an important factor on to which economies depend and prevail. Independence in energy leads to prosperity and economic progress in the country. The significance of energy generation cannot be unrecognized due to its crucial share in the industrial practice and growth of the
Over the past decade, energy has brought social, economic and environmental advantages and played a major role in the urbanisation and industrial revolution. However, after the uncontrollably frequent use of these energy sources, depletion of these energy sources also became a major concern which brings about its own economic, social and environmental disadvantages. Of a particular concern is the availability of these energy sources which affects both industry and the lives of the consumers.
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.
Securing a sustainable future for electricity can be ensured by introducing renewable energy sources to develop a sustainable weighting of the three Economic, Environmental and Social pillars of sustainability. It is known today that the world needs sustainable electricity sources to produce energy, as our natural recourses such as coal are running out. The burning of coal for energy produces an output of carbon dioxide, which is the leading cause to global warming the detrimental effects on the future of the environment. The world has access to many sources of renewable energy such as, wind power, solar power, and hydro power. Although, renewable energy does not produce the majority of the worlds electricity as the conversion to renewable energy sources has been difficult due to lack of funding the governments are willing to pay across the world.
For decades a certain problem has been slowly growing day-by-day. Today the problem has been more prevalent than ever before. In recent years the current energy usage, which is fossil fuels, is not sustainable and carries negative effects to the environment. However nothing is perfect, even renewable energy has its fair share of disadvantages. Can alternative (reusable) energy sources such as nuclear, hydrogen, biofuels or solar energy meet the energy demands needed by humans to carry out their everyday tasks such as electricity, commuting, and so on better than fossil fuels such as coal and oil which creates a mast amount of energy today. Fossil fuels are considered to be unsustainable, environmentally destructive, inefficient, and the primary contributor to global warming. It is estimated that about 88 percent of global energy is produced by burning fossil fuels5. Additionally, only 12 percent of global energy is produced by clean alternative energy sources5. It is time for individuals to think whether alternative energy can efficiently replace fossil fuels.
After experiencing the replacement of manual and animal labour by steam engines in the Industrial Revolution, cheap fossil fuels then became the main source of energy. However, faced with the notable increase demand for energy, fossil fuel, as a non-renewable resource becomes scarcer and more expensive nowadays. To solve this problem, the world needs to replace fossil fuels with other sources of energy which are relatively low-cost and more secure. Renewable energy is such a potential energy. This essay will give an outline of three sources of renewable energy to be used in developing nations, which are solar energy, wind power and biomass. First, it will give a definition of fossil fuel and renewable energy, then it will move to analyse
The most of global energy production produces from fossil fuel such as coal, oil and natural gas. The vast fossil fuels generate energy which use for many purposes for instant residential, transportation and industrial sectors. While the rate consumption of fossil fuel higher than their formation leads to oil price crisis. Another concern of fossil fuel combustion is the impact on the environment. Global warming is a significant problem which results in increasing concentrations of greenhouse gas in the atmosphere. These problems drive researchers and societies to search alternative energy such as switching to renewable energy or carbon-free energy to replace fossil fuels. For example Nakata et al., (2011:465) show ‘low-carbon society’
Energy is one of the main drivers of economic and social development. Years ago, the only uncertainty was the price of oil. Now the concern is if the current economic model growth is reasonable in a world with limited energy resources. This has lead to more research in other forms of resources of energy. Now we have other unconventional resources such as wind, solar, geothermal, water, and so on. Energy demand is set to double by 2050 (Beckman, 2013). Therefore, greenhouse gases could double by 2050 as well. Hence, renewable energy is vital. However seen as fossil fuel is still the dominate source of energy, it makes it the current economic model growth rate somewhat unreasonable.
Energy play a vital role in our day to day life. We can’t think our life without energy. Everyone who is existing on earth want energy for surviving his life.Today our world’s population is in order of billion and it is continue to increase very rapidly so, our demand for energy is increasing drastically in recent time. Our conventional source of energy like coal, petroleum
Over the past few years, energy consumption and sustainability have become a major concern to many industrialized countries across the globe. These countries still depend on burning fossil fuels such as coal, oil, and natural gas to produce most of the energy they need. According to the United States Energy Information Administration (EIA), fossil fuels made up 81.5% of total U.S. energy consumption in the year 2015. The issue arises when you consider that these resources are finite and will run out eventually, leaving a big problem for future generations to address. Another complication involves the fact that our dependence on fossil fuels is having a negative impact on the environment. Human activity, more specifically, the burning of limited resources to drive cars, generate electricity, and operate our homes is the primary cause of global warming (“Concerned Scientists”). As we begin to understand climate change better, many countries are turning to renewable energy sources in an attempt to reduce their carbon footprint. Some examples include the installation solar panels and wind turbines, as well as building dams that produce hydropower. I believe that we must work together and embrace these new, alternative sources of energy in order to preserve a healthy environment.
Demand for energy is increasing every day due to the rapid growth of population and urbanization (Kalayasiri, 1996). According to International Energy Agency (IEA) (2009) data from 1990 to 2008, the average energy use per person increased 10% while world population increased 27%. About 80% of this energy demand is delivered from fossil fuels with the consequence of an increase of greenhouse gas emissions in the atmosphere that provokes serious climate changes from global warming. The world today is heavily dependent on fossil fuels. The global increase in carbon dioxide concentration is due primarily to fossil fuel use and land use change, while those of methane and nitrous oxide are primarily due to agriculture (IPCC, 2007).
The role of energy in human life dates back to as far as the ages of civilization where ancient people needed fire not only for comfort but also for cooking (Michaelides 1). In the modern digital world, everyone has his or her uses of energy with other similar uses all of which affects the life of everyone. Notably, there is the production and use of energy in varying forms like in automobiles, airplanes, and manufacturing plants. Conversely, with the global trend in need for a sustainable earth, the shift from environmentally unhealthy energy sources has led to the public call for alternative energy sources (IEA 9). The transition to alternative energy sources aims at conserving the natural resources as well as protecting the environment. The energy sources include fossil fuels, the wind, geothermal, hydropower, solar and nuclear power applied in various uses modern life operations locally and internationally (Brkić 36 and Wadud et al. 18). However, although there is a globalized rise in the use of fossil fuels, the environmental and climatic implications calls for the shift to alternative energy sources. Through the analysis of alternative and fossil fuels, the essay provides an elaborate explanation useful in the maintenance of a sustainable world.
Throughout the 20th and 21st century, our knowledge about the environment and energy has steadily grown, as well as our dependence on them. Nowadays, power and electricity are in every facet of our daily lives. Due to this, we overlook several negative effects our traditional use of fossil fuels have caused. Fossil fuels are fuel deposits that were formed hundreds of millions of years ago, which is where the term fossil fuels come from. The two most common fossil fuels currently in use are coal and oil, which power the majority of our infrastructure. However, fossil fuels are known to have some drawbacks which is where projects for alternative energy come into play. Alternative energy, or also known as renewable energy are energy sources
Energy sources have been identified as being vital in running virtually all domestic and industrial operations. There are two types of energy sources; renewable energy sources and nonrenewable energy sources. Renewable energy sources refer to the kinds that are naturally replenished. These include sunlight, the wind, ocean tides, waves, geothermal heat and rain (Tiwari et al., 2012). Nonrenewable energy sources, on the other hand, are the kinds that do not renew themselves at a rate sufficient enough to meet human demand. Fossil fuels such as coal, petroleum, and natural gas, minerals, metal ores and groundwater all comprise nonrenewable energy sources (Verma et al., 2015). In recommending the category of choice having weighed the benefits and demerits of each, science has played an important role. According to scientific research, nonrenewable sources of energy are not recommended due to the massive demerits that come with their use.
