Electricity still remains the most important energy source in the present world driven by information and communications. There are quite a number of energy sources but under two broad categories - renewable and non-renewable energy source. The non-renewable energy sources include coal, gas, crude oil etc. The renewable energy sources include solar energy, wind energy etc. Non-renewable energy sources are burnt and cannot be replenished but renewable sources are not diminished when they are used.
One down side of non-renewable energy sources which have been widely used in the past centuries up till now is the air pollution they ...

It used to be so easy. For tens of thousands of years, humans used wood-burning fire to heat their dwellings, to cook their food, to forge simple tools. Tens of thousands of years before that, human’s ancestors harnessed the power of fire, giving them a hunting advantage over other animals. Then, the population started to increase, especially after the Plague had ravaged much of the world’s population. Wood became scarce, especially in places of dense population, such as England. The increasing rarity of the resource made the demand for another source of energy greater than the demand ...

Elimination of Subsidies for all Energy Alternatives

I agree with the proposal to eliminate government subsidies for all energy alternatives so that all energy providers can compete in a free market economy. My rationale for agreeing with this proposal is that providing subsidies is a retrogressive economic policy that allows the government to prop one sector of the energy industry at the expense of other sectors. Rather than foster competition, government subsidies will give alternative energy investors unfair price advantages over other energy providers. Moreover, subsidies will cause the alternative energy sector to become less cost competitive and encourage unhealthy dependency on preferential treatment from the ...

Papua New Guinea, Indonesia, New Zealand, and The Philippines

Four countries that rely on fossil fuels are also four countries racing to learn how to utilize more renewable energy than they have done in the past. Each country has the ability to use geothermal, wind, solar, and hydroelectricity power and rely less on oil, coal, and natural gas reserves. Each country has the opportunity to change and there is support for these changes to reduce greenhouse gas production by the middle of the twenty-first century.
Philippines have been switching to more renewable energy than before, while still relying on non-renewable energy sources, such as gas and oil. However, ...

If you pay attention to too much of the mass media, you might think that renewable energy is a pipe dream proposed to solve a nonexistent problem. After all, the presumptive nominee for the Republican Party in the upcoming U.S. presidential election, Donald Trump, sat down with the editorial board of the Washington Post back in March and told them, “If you look, they had global cooling in the 1920s and now they have global warming, although now they don’t know if they have global warming” (Leber & Aldern 2016, web). Trump has even gone so far as to ...

Sustainable Technology – Solar Power Generation
Power Generation from Fossil Fuels and Global Warming
Global warming, as defined by Lineman, Do, Kim and Joo (2015), is the long-term trend of increasing average temperature of the lower atmosphere. It is widely known that this phenomenon is related to the concentration of greenhouse gases that trap heat in the atmosphere, such as carbon dioxide, methane, nitrous oxide, among others.
Activities related to human development such as industrial processes, agriculture, cattle raising for meat consumption, transportation, deforestation and power generation are the major causes of greenhouse gases emissions. Specifically, power generation based on ...

Whether Renewable Energies Can Make a Major Contribution to the Global Energy Budget and Further Policies Needed To Achieve This.

The question of whether investment in renewable energy production will help reduce the global expenditure on energy production should be viewed on economic, social, and environmental perspective. Economically, expenditure on renewable energy production is currently higher than energy production from most non-renewable sources (Wengenmayr and Bührke, 2011). This explains why subsidies are often being offered to promote production from renewable sources. A study by the institute of physics at the University of Oldenburg found that the ...

Introduction

While non-renewable energy sources, notably fossil fuels, comprise the main sources of energy today, concerns over sustainability, high oil prices and climate change, have forced the issue on need for alternative energy sources. The increased contribution of renewable energy sources across all economic sectors means that these technologies can assist countries to meet their respective policy objectives for secure, affordable and reliable energy. Renewable energy technologies remain in their infancy, but are fast gaining ground because of the unsustainably high costs, carbon footprint and pollution caused by fossil fuels.

Introduction
Some scholars view energy as an abstract concept that could not be defined by any physical parameters (Lehrman 15). There are those who even admit that they do not know the scientific meaning of energy because it cannot be seen or touched or smelled except that it can only be imagined through its effects. For the same reason, some scholars refrain to define energy to avoid being misconstrued. Engineers, however, need an operational definition for energy in order to apply its concept in many engineering applications such as in mechanics, thermodynamics and electromagnetism. Engineers, especially during ...
