Use of Fossil Fuels for Power Generation and the Need for Renewable Energy

According to Nelson (2011), more than 85% of the world’s energy consumption, which is estimated at 520 exajoules, is generated through the burning of fossil fuels such as petroleum, natural gas and coal (p.19). Electric power generation from non-renewable sources will, unequivocally, result in their exhaustion and creation of a major energy crisis. For this reason, it appears primordial to shift in a greater scale to alternate power generation, such as solar, wind, hydroelectric, etc. Amongst these, Sorensen (2011) explains that though hydroelectric power does represent one of the major forms of power generation, its growth is stagnant ...

Benefits of Green Schools in Kuwait

CHAPTER 1: INTRODUCTION Kuwait is a country located in the Middle East, which is a region characterized by severe water shortages as its located in the middle of a desert. Also, nearly all the electrical energy consumed in Kuwait is generated from fossil fuels such as natural gas and diesel. This situation poses several challenges. For example, the lack of enough clean water for domestic use could lead to serious problems such as waterborne diseases, such as cholera or typhoid. Also, water shortages can affect businesses such as agriculture and hospitality businesses. On the other hand, over reliance on ...

Executive summary

In the past, we have seen a considerable number of children born prematurely succumb to death shortly after delivery (Koletzco, 2014). This is most prominent in the developing countries for obvious reasons where infant mortality rates are more pronounced. Babies born underweight or premature are in dire need of someone to come up with innovation to bridge this gap. The innovation of infant warmers would go a great mile to help these infants. An infant warmer is a sleeping bag for infants which serves the purpose of an incubator. One thing about the infant warmer is the fact that ...

Introduction

Over time, the growth of a city of a locality leads to the increase in the demand for electricity. The growth in population and the commercial activity puts pressure on the national grid. Without commensurate investments in the generation of power, the increase in demand results in shortages. To supplement the shortage of electricity in the region, more power can be brought in from the generation sources. However, this is complicated if the power generation plants are located far away. This is because more high voltage overhead transmission lines would be required. The Ministry for the Environment (2010) finds ...

REPORT SECTIONS

Annually, infant mortality is recorded at 1million globally with 98% of this cases being in the developing world (National Center for Health Statistics -US. 2014). The documented cause for these deaths includes preventable and treatable complications which are linked to prematurity and low birth weight together with hypothermia. The proposed innovation thus seeks to solve this problem using the product- infant warmer.

Product or service description

The proposed innovation is an infant warmer. An infant warmer is a portable sleeping bag for infants which serves the purpose of an incubator. One thing about the infant warmer is the fact that it does not ...

- Introduction Solar cells function by converting solar light energy into electricity. It functions on the basis of the photovoltaic effect. “Photo” stands for light and “voltaic” means electricity (light–electricity). A solar cell is capable of providing DC current. This DC current can be used to light bulbs and power DC motors. Rechargeable batteries also use this DC current, which can be utilized later on when the sun is not available. Also, these batteries, when fully charged, are portable and can be used wherever and whenever you want them (De Vos, 1980). Solar cells are comparable ...

Abstract

The project deals with the problem of solar power that is an environmentally safe alternative to the currently used sources of energy, such as oil, gas and coal. It is proved that renewability, an ecological safety and a relatively constant availability of this energy sources are the main advantages of solar power. However, technological expensiveness of energy retrieving appliances, especially in the case of space-based solar power, is cited as one of the main disadvantage that prevents the USA from putting solar energy to a good use unlike Germany where state dotation and solar program flexibility allow the unrestrained installation of ...

Sun plays crucial role in the life of the Earth. The entire organic world of our planet is obliged to the Sun for its existence. It is not only the source of light and heat, but also the original source of many other types of energy (oil, coal, water, wind). Since people appeared on the Earth, they began using the sun's energy. According to archaeological data, it is known that housing preference was given to quiet places, closed from the cold winds and open to the sun's rays. Perhaps the earliest known solar system can be considered the ...
