Here is your short essay on Energy!
Energy is a primary input for almost all activities and is, therefore, vital for improvement in quality of life. Its use in sector such as industry, commerce, transport, 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. The energy related problems are as old as 2500 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.
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). People living in industrialized or developed countries are a relatively small percentage of the world’s total population, but they consume a huge share of the total energy produced in the world.
The main issues regarding the energy problem in urban areas are:
(a) How to utilize the energy from non-renewable sources at their maximum efficiency.
(b) How to make use of renewable sources of energy or the alternative energy sources?
Energy policy today has two choices (paths). One path leads to the fossil fuels (hard path), which means continuing as we have been for a number of years i.e., emphasising energy quantity by finding more amount of fossil fuels and building much larger power plants.
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.e. 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 level. In addition, measures to conserve energy need to be followed.
Energy conservation is considered as a quick and economical way to solve the problem of power shortage as also a means of conserving the country’s finite sources of energy. Energy conservation measures are cost effective, require relatively small investments and have short gestation as well as pay back periods. The studies conducted by Energy Management Centre, New Delhi have indicated that there is about 25% potential of energy conservation in the industrial sector.
Essay on climate change - Kyoto agreement In particular, solar energy is regarded as the most resourceful energetic sources to be widely applied in the foreseeable future. The energy potential of the sun significantly (by 35,000 times) outnumbers the actual consumption of energy by mankind. Nonetheless, we do not get all this energy from the sun as 1/3 of it is absorbed by atmosphere and is reflected backwards to the space. Potentially, solar energy will be soon used to run power plants, cars, space ships etc. Next, wind power is widely applied as an alternative energy resource without producing harmful effects to nature.
Alternative Energy essay: Renewable Sources ...the application of alternative energy sources to save the actual capacity of energy. This is done in a reasonable economic and environmentally friendly manner to face many global challenges related to the rising consumption of global resources. Alternative energy sources are not based on splitting of atoms or burning of fossil fuels.
Child Obesity Essay Teenager’s caloric needs vary depending on their growth rate and activity level. Males generally have higher energy requirements than females due to their larger proportion of lean body mass to adipose tissue Consequently, a well-balanced diet provides energy and nourishment necessary to lead normal life, and therefore to keep fit.
Essay on greenhouse effect In the U.S., our energy-related activities are known to account for three-quarters of our human-generated greenhouse gas emissions. These are usually expressed in the form of carbon dioxide emissions from burning fossil fuels. Also, more than half the energy-related emissions are known to come from large stationary sources.
Technology progress essay: The impact on society and on business Businesses constantly seek effective and convenient sources of cheap and possibly unlimited energy (Urban, 1998). The development of such energy sources will cause revolutionary changes in all business areas; cheap and unlimited energy is particularly important for the continuity of business performance.
Global warming Essay ...as a result of the increased energy consumption. The energy was obtained by driving and using electricity and through other activities... As a matter of fact people have “to get investment flows going in the direction of emerging clean energy technologies. Part of that's going to happen because we, as consumers, step forward and we are conscious in our buying habits to get more energy-efficient products.
