1.1 Background
The rate of a country’s growth and development is driven by the amount of energy available in that country. Global energy demand is increasing due to population increase and rapid industrialization which began in the 21st century (Dilip and Marika, 2009). As domestic and industrial systems make use of the available energy produced by energy systems, technological advancement is crucial for these systems to maximally utilize the available energy sources in the world; thus meet up with the expected demand. Energy source is generally classified as renewable and non renewable. Non-renewable source also called a finite source is a source of energy that does not renew itself at a sufficient rate for sustainable economic extraction

An example is carbon-based organically derived fuel. The original organic material, with the aid of heat and pressure, becomes a fuel such as oil or gas. Fossil fuels such as coal, petroleum, natural gas e.t.c are all non-renewable resources. Renewable energy is generally defined as energy that comes from resources which are naturally replenished on a meaningful human time frame. Renewable energy resources include hydropower, biomass, geothermal, wind, solar e.t.c. These renewable energy sources have great potential to meet the world’s energy need of the future. It has been identified that, the proportion of renewable energy and non-renewable energy usage in the world has wide overlap (IEA, 2008).The world depends majorly on non-renewable energy sources to drive its economy. This dependence on non-renewable energy source is not enough to meet up with the growing energy demand and future energy security of …show more content…
The implication of this is that about 87% of renewable energy is needed in addition to 13% present renewable sources to replace non-renewable fossil fuel. Researchers have argued that it is not possible for renewable energy to replace this large percentage of energy occupied by non-renewable sources in the present human time scale due to the huge economic and technological challenge faced by renewable energy systems. Another argument is that fossil fuel will soon finish! Perhaps not completely true since more oil reserves are being discovered within time scale. However, based on Nigeria’s present fossil fuel reserve of 37.2billion barrel crude at an average production rate of 1 billion barrel annually and 187 Trillions of standard cubic feet (Tscf) of natural gas at an average production rate of 2.4 Trillions of standard cubic feet annually (Bala and Pam, 2012), it can be estimated that non-renewable fossil fuel resource will continue to be available for hundreds of years. Also, renewable biofuel is a welcome technological development for replenishing and producing natural gas from renewable sources. Technologies for mitigating climate change and reducing global warming caused by combustion of fossil fuel are being developed. A common method employed in such technology involves carbon dioxide capture and sequestration (Johnson, 2011). This
“If we do nothing, it doesn't matter how we feel. And that’s exactly what oil companies are banking on: out of sight, out of mind” (Hart, 24). In his article, 50 Miles Out, Brandt Hart explains the controversy surrounding offshore oil drilling along the east coast. This argument on whether to end or continue drilling started when new oil and gas leasing programs were made for 2017-2022, which included plans for oil and gas “exploration and development” in federal waters (Hart. 24). This plan also includes more oil drilling along American coasts, more specifically the Gulf of Mexico and east coast of the U.S.
Hydropower dates way back to two thousand years ago, the first culture recorded in history to find use of water other than drinking and sailing were the Greeks. They have created a water wheel as a method of using water to grind down wheat into flour. In the time of 202 B.C and 9 A.D, the Han Dynasty, water power was used to break ore and was used for paper-making. For over a thousand years no one has constructed a new use for water power. Until in 1712, Thomas Newcomen from england developed the first steam engine.
The world is in need of fossil fuels. Without them, we would not have cars, airplanes, and not to mention enough energy. A lot of energy is produced from them. They are a very big support. Unfortunately, they are running out.
Sustainability Blog Title: Renewable Energy in Iowa The Upward Bound theme for the summer of 2017 is water. On Tuesday, June 6th Tracy Spry from the U.S. Army Corps.
Burning fossil fuels is one of the main culprits that causes climate change because it releases gases into the atmosphere that trap in heat and create the greenhouse effect. According to Klaus S. Lackner, the director of the Center for Negative Carbon Emissions and a professor in School of Sustainable Engineering at Arizona State University,”Dumping carbon dioxide and other greenhouses gases into the air raises their concentrations in the atmosphere and causes gradual warming.” This gradual warming is causing many horrific effects
There is a quote by President Barack Obama saying, “To truly transform our economy, protect our security, and save our planet from the ravages of climate change, we need to ultimately make clean, renewable energy the profitable kind of energy,” (“151 Inspiring Environmental Quotes”). He believes as many due that nonrenewable resources are harmful to all aspects of life. The energy we use now is harmful to our planet, to humans, and to animals. Scientists are taking steps to making the world a better place. They found sources that replenished naturally in a short amount of time and are less destructive in all aspects.
Angel Hsu A block Solar Energy 12/22/2015 “Because we are now running out of gas and oil, we must prepare quickly for a third change, to strict conservation and to the use of coal and permanent renewable energy resources, like solar power. ”(Jimmy Carter, televised speech,1977) Just like what he said, we should develop other energy than fossil fuel because we will run out of it some days and fossil fuels are the main reason of global climate change.
Introduction In today’s world, most developing countries are in a race to build up the necessary infrastructure to scale up there operations and become the next global superpower. In this process, a lot of energy is consumed – be it for transportation, manufacturing or construction. This rapid growth of energy use seen over the past two decades have raised concerns for governments and energy-related organizations alike. Questions with regard to the supply, sustainability and exhaustion of energy sources abound, and while most developed countries have taken active steps to reduce consumption of scarce resources, the position of developing countries in this regard is still lacking.
Scientists have found that renewable energy is a path towards the future for a clean and safe environment. Throughout all the studies and findings, there is a continuing fret whether people should be able to use a traditional way of energy or renewable energy, solar power. Solar energy is seen to be effective since there has progressively been more places that are benefiting from solar usage; however there are also some who disagree. Solar energy sources are derived from natural sources and is implicated throughout our daily lives. From the lights in the streets to the computers we use at home.
For many years now, it has been debated which of the new and upcoming renewable and sustainable energy sources if the best to use. Energy create from wind, is a very favourable contented in this debate as it is a very good alternative energy source. Wind energy is used all around the world. Humanity has been using wind energy for over 100 years. For example, we used to (some still do) use the wind energy to grind grain in old fashioned wind mills..
Non- fossil fuel energy has a lot of trouble producing the amount that fossil fuels can produce. This means we need to cut down on the amount of energy we use or just build a lot more production facilities. Another downside is that renewable energy relies on weather 90 percent of the time. If there isn 't rain to fill the dam the Hydro generators can 't run. If there isn 't wind for the wind turbines it wont go.
Arguably the most significant thing humans have done to cause climate change is the drastic increase in CO2. As a result of human activities, carbon dioxide, methane, nitrous oxide, and the halocarbons (a group of gases containing fluorine, chlorine, and bromine) build up in the atmosphere over time, as well as the natural sources of CO2, like vegetation. The concentration ofCO2 has went from 280 to more than 380 parts per million in just two hundred years. Still currently rising, the burning of fossil fuels by humans will continue to cause global warming and climate
2.1 INTRODUCTION Non-Renewable Resources are resources that have the potential to be used up due to consumption or overuse, they have production, development or replenishment rate that cannot match up with the depletion rate. In short these are resources that can be finished, output exceeds input, and they are infinite. Non-Renewable resources vary from non-renewable fossil fuels like coal, natural gas and oil, non-renewable alternative energy sources like nuclear energy and deep-earth geo-thermal energy, soil, and minerals (Botkin & Keller, 2012). These non-renewable resources range from a few years, up to thousands of years to replenish. The local as well as global challenge, is that most non-renewable resources are directly exploited by humans and their existence is widely threatened were usage
Renewable energy is generally defined as energy that comes from resources which are naturally replenished on a human timescale such as sunlight, wind, rain, tides, waves, and geothermal heat. It is the energy which is abundant in nature. The sun is the ultimate source of energy. Almost all the energy that we use eventually comes from the Sun. The exception is the heat of radioactivity deep inside the Earth, which is ultimately responsible for processes taking place inside the Earth.
For instance, in Vietnam fossil fuels is the main fuels to address basic demand and for export, but in 2030 Vietnam
