Its use essay on energy sector such as industry, commerce, transport, essay on energy, telecommunications, wide range of agriculture and household services has compelled us to focus our attention to ensure its continuous supply to meet our ever increasing demands. Energy related problems are not new, essay on energy. The energy related problems are as old as years ago. The early Romans and Greeks faced fuel shortage as wood was their primary source of energy. They had to import wood from very faraway places. Fossil fuel is still the main source of energy.
Today we are facing the peak of oil and gas utilization. Fossil fuel resources took millions of years to form and are infinite, essay on energy. These resources may be exhausted in a few hundred years. Historical evidence shows that world energy demand has increased at almost the same rate as gross world product GWP. Energy policy today has two choices paths. One path leads to the fossil fuels hard pathwhich means continuing as we have been for a number of years i. The second path is the soft path which leads to the energy alternatives that emphasize energy quality and are also renewable, flexible and more environmental friendly.
The soft path relies mainly on renewable energy i. sunlight, wind biomass, tidal energy etc. There is a need to resort to energy management. This concept recognizes that no single energy source can possibly provide all the energy required by the source nation. Thus, the basic objective of the integrated energy management is to obtain sustainable energy and which should be realized at the local essay on energy. In addition, measures to conserve energy need to be followed. Energy conservation measures are cost effective, require relatively small investments and have short gestation as well essay on energy pay back periods. You must be logged in to post a comment.

how to write the best persuasive essay
However, this manner of energy production often results in by-products such as soot, smoke and other substances that pollute the environment. Some of the primary air pollutants that result from the combustion of fossil fuels include carbon monoxide, sulfur oxides, nitrogen oxides, particulate matter, and unburned hydrocarbons. Carbon monoxide is a highly poisonous gas, and is the primary constituent of smog. Carbon monoxide pollution is caused by urban automobiles and transportation vehicles. According to ACEA , as of , there were more than million automobiles on European roads. About 34 percent of these cars are older than 10 years, and the car density per a thousand inhabitants was in Western Europe in What this means is that these older cars are likely to have incomplete combustion of fuel leading to the production of carbon monoxide as well as sulfur dioxides and particulate matter.
Considering that there are about cars per habitants, the health effects resulting from this air pollution can be adverse. These pollutants can cause respiratory problems such as bronchitis and also irritate the lungs. Also, nitrogen oxides and sulfur oxides combine with water to form acid rain, which can harm aquatic ecosystems as well as crops and forests. In addition to these forms of pollution, the burning of fossil fuels has created the greater problem of global warming. Carbon dioxide is one of the gases that are emitted during the combustion of fossil fuels. Carbon dioxide traps heat in the atmosphere, and this has resulted in increasing global temperatures.
Also, the emission of other greenhouse gases such as fluorinated gases, nitrous oxide and methane has led to the destruction of ozone layer. Global warming has led to climate change, resulting in altered weather patterns that have seen led to extreme weather events such as Tsunamis as well as droughts. However, there have been efforts aimed at ensuring that the conversion of energy is done in a clean and sustainable way. One of the most notable agreements is the Kyoto Protocol. Under this protocol, 15 EU member states committed themselves to reducing their collective emissions in the period to 8 percent below the level. It is the Intergovernmental Panel on Climate Change IPCC that creates a standard reporting format for GHG emissions from countries.
In order to achieve these commitments made in the agreement, there is a need for the adoption of Green energy governmental policies such as subsidies on renewable energy production. For example, in , European leaders put a signature on a binding EU-wide target to source 20 percent of their energy needs from renewable sources of energy such as solar, hydro, biomass and wind power. As a member state, Ireland has a National Renewable Energy Action Plan aimed at meeting the renewable energy targets set by the European Union. For example, Wien Energy built the largest wood biomass power plant in Europe in the year The plant provides electricity for about households and heat for households.
According to DAC , generating the same amount of electricity and heat is equivalent to using tons of fuel oil or tons of hard coal. The power plant reduces an estimated tons of carbon dioxide emissions annually. The success of this project can be attributed to subsidies guaranteed by a higher feed-in tariff. In addition to these policies and programs, there is also a need to explore clean ways of converting fossil fuels from one form to another. For example, there are a number of technological developments in coal-fired generation. Such technologies include supercritical-pressure pulverized coal combustion, integrated gasification combined cycle and carbon capture and storage. Incentives for econ-innovation have also led to new car technologies that reduce carbon dioxide emissions.
Therefore, there is a need to consider the effects of energy conversion methods when studying energy. The paper "Free essay on energy conversion" was contributed to our database by a real student.

We would. Without energy how will we able to use transportation? Nobody wants to walk to work or to school that would be a major crisis. The energy from the sun gives us sunshine so we can see. When we eat energy been here for centuries, the word energy even sounds powerful, energy is one of the most powerful things in the world. Energy is the ability to do things such as playing, running. What is Geothermal Energy? The term geothermal comes from the Greek geo meaning earth and therine meaning heat thus geothermal energy is energy derived from the natural heat of the earth. The heat that flows from the Earth's hot interior due to crustal plate movements, zones of high heat flow, may be located close to the surface where convective circulation plays a signifcant role in bringing the heat close to the surface World Bank Group, The Earth's crust, on which we live and depend.
and the surface ocean over most of the globe. The energy source that drives this pump is solar radiation from the sun. This long term pump has ceased in Mars. This energy is called solar energy, which is the energy I have chosen to research. As you will read later on, solar energy can be very useful. Some of the first people to discover solar energy were the Greek and Romans. For example, Romans would cover building openings with glass in order to store the heat from the sun. Solar energy has been in use for as far back as. Between and , energy production and consumption increased in every region of the world except in Eastern Europe and the former Soviet bloc. East Asia and Oceania saw a production increase of Energy production in the Middle East increased by Energy production in Central and South America.
Energy Energy is a crucial necessity and with the ever increasing need for it and the high and fluctuating prices of oil, researchers are constantly coming up with newer and more sophisticated alternative sources of energy. However, energy comes at a cost, as it is either expensive or it possesses high health risks. This essay presents the concept of energy by discussing the two major types of energy, the various forms it could take, including renewable sources of energy, energy conservation and. Without this energy, whole countries can collapse, and the human race would struggle to survive.
Therefore, it is safe to assume that we as a nation are entirely dependent on energy, or the ability to do work Gale Science in Context. Consequently, we are now actively searching for more cost efficient and useful forms of energy to replace those we currently use. By doing. In recent years, energy has become more vital to support the economy and its consumption, which is still dominated by fossil fuels, has risen significantly over the last two decades. Among the countries, there are concerns about reducing the dependency on the conventional fuel. Therefore, the alternative energy has become contemporary issue as a part of solution. One of the most progressive is geothermal energy. In many aspects, this article is undertaken to review about geothermal overview and its.
of one sort of energy into another.
