This is because it significantly contributes to pollution and triggers global warming. Therefore, it is not safe to use coal and other non-renewable energy as power source. Renewable energy sources are infinite energy resource and this implies that they never run out. This report compares and contrasts these two sources of energy in relation to cost and safety.
This report is well structured and coordinated to ensure that all the ideas presented flow smoothly. Both primary and secondary sources have been used exhaustively to acquire important and relevant information to write this report. The information has also been acquired though surveys, telephone, mail as well as internet surveys. Extensive research has also been conducted to make this report effective.
Coal is not expensive as compared to solar energy, but again solar energy costs are dropping. Coal may not be expensive but it requires expensive air pollution controls such as mercury because it emits higher levels of carbon dioxide. It has a higher environmental impact from mining and burning since the carbon dioxide released during the process contributes to global warming and creates acid rain (Evans 2005, p.138). Coal mining has always been known to be dangerous and associated with many problems (Britton 1977, p.118). Moreover, coal as a source of energy is a significant contributor to acid rain and global warming and this is directly linked to its pollution ability because it emits major greenhouse gases that play a leading role in triggering global warming and climate change. Solar energy is somehow cheap because sunlight is usually free when available (Chiras 2014, p.363). Solar energy does not generally cause pollution but there are some emissions associated with the manufacturing, ...Download file to see next pagesRead More

Solar energy the nearest and biggest star and the source of energy for the planet of Earth. The sun's energy has been in use for a lengthy time, and it is a critical part of life. The solar energy is a fundamental need for humans. The image of the sun has many theories, histories and myths associated with it. For centuries, it has been the God, or the holy part of different religions, for example, the American native tribes and Greeks worshipped it. It is also an essential part of many religions as they hold it dear to their worship, for example, Hinduism, Buddhism and druids of England hold the sun as the precedence of their...

Renewable Energy Future for the Developing World

...The introduction of nuclear energy for peaceful purposes, biogas, wind energy, solar energy and hydropower has certainly threatened the oil and gas industry; however, the influence of these substitutes is still not significant because of their high costs, less ease of use and other factors. However, obtaining energy through coal poses a significant threat which, however, is also conditional on technological advancements which would allow use of coal as sources of energy (Ernst & Young 2012).

...?Solar Energy in Arab Countries Most of the Arab countries have shown phenomenal and extraordinary development within a pace of few decades. Natural resources have always been doing wonders for a vast majority of the Arab countries. The way Arab countries have used oil to take their economies to the apogee of success is a potential example of this. In the recent times, more and more Arab countries are considering ways to become more environment friendly and greener. A very important idea of the Arab countries in the present age is to drive their plans of concentrated solar power (CSP). Two transmission projects and nine CSP plants with a total power of...

...itself is renewable. The maintenance costs of solar power are also quite low compared to other forms of energy (Thomas 11). It is also quite easy to install solar panels which are available at relatively low costs. Solar energy can also be used in any setting, be it at home or an industrial setting. Another main pro of solar energy is its reliability. This is an energy source that will never be affected by geographical, economic or political upheavals (13). One of the major disadvantages of solar power...

Solar Energy technology because it is not only cost effective in the long term but it is also very environmentally friendly. In comparison to coal energy, which needs large amounts of coal to produce, solar energy requires only proper technological structures designed to harness it in order to produce massive quantities of electricity, even more than what coal produces. Since the beginning of its usage, there has been a lot of debate about the use of solar power in many countries and this has recently intensified due to talk of a coming renaissance in its use. This form of...
