The Modern Hero of Energy Production
Natural catastrophes seem to be happening more and more frequently these days: flooding, tsunamis, earthquakes, hurricanes, landslides, and so many more. Every television station displays the same sensational headlines—“the west coast of America slammed with rain”; “the east coast buried in snow.” The catastrophes are no different than they have always been, but many people are now concerned about the frequency of these catastrophes. There are many scientists out there who are pointing the finger at global warming. Because of global warming, our weather patterns are changing quite dramatically and it is Continue reading...

The wind is a clean and plentiful source of renewable energy that is currently being explored worldwide. It offers a reliable alternative not only for non-renewable sources of energy but also renewable energy including solar energy (Thomas 119). Wind energy is used for various purposes including sailing vessels, powering factory machinery, pumping water as well as grinding grain. Turbines are used to generate wind energy in a process called Wind power. Wind power is widely recognized for its ability to generate power that can be utilized feasibly and economically in large quantities. It is an environmentally friendly process since Continue reading...

Since the earliest moments of civilization, wind energy had been implemented. The mentioned wind got used for grinding grain, powering sailboats and pumping water from wells. Categorically, before the installation of electric infrastructure in the United States, both little wind power turbines and water pumping windmills were essential. The mentioned were vital for the development of American Great Plains, as well as, the west and farming. Prevalently, the United States enjoys the resource of strong wind in the entire nation. Currently, the potential of wind energy is around ten times the quantity of electricity being consumed in the whole Continue reading...

The wind power is a system of a natural energy production. The wind turbines use an energy of a wind to generate electricity. Energy production from the wind is a complicated topic. Having both the advantages and disadvantages, the wind power should be evaluated thoroughly on such vitally important criteria as: an influence on human health, a creation of the new working places, a choice of the wind turbines locations, а search for the new, alternative renewable energy sources.
Human health, the priceless treasure, must stay first in the wind power evaluation list. The wind power production may cause the Continue reading...

- The Causes of Global Warming
Global Warming has always been an issue of debate, with environmentalists vehemently raising their voice against it. The main reason cited for global warming by researchers is the emission of greenhouse gases largely because of ever-increasing population and related changes in standard of living (Derek Markham, 2009). The main greenhouse gases causing this effect are carbon dioxide, Chlorofluorocarbons (CFCs) and methane (WMO, 2011). These are caused mainly by burning of fossil fuels such as coal, oil and natural gases for generation of electricity, running vehicles, warming and other industrial processes.

Sustenance of the environment is a key pillar in the growth of the European Union and other economies in the world. Continue reading...

Energy is a requirement for the creation of finished goods from natural resources and for the provision of various services. It is therefore, a major building block for any society (Hinrich and Kleinbach, 2006 p.1).
In the world we live in, about 85% of energy resources used commercially come from fossil fuels such as natural gas and crude oil (Hinrich and Kleinbach, 2006 p.26). Asphund (2008) says that fossil fuels have provided great service to the world by providing a cheap fuel supply that has driven two centuries of industrialization.
However, fossil fuels have several problems associated with them Continue reading...

Renewable Energy

Global warming continues to present problems not just for developing countries but also to developed countries as natural calamities worsen, man-kind continuously abusing and depleting the environment’s many gifts and the world continuously becoming either warmer or colder in seasons which should not be possible. Eastwood (2011) stressed that many factors have been attributed as to how global warming continues to persist; one of them being the use of non-renewable energies, such as fossil fuel, which releases carbon enough to reduce the ozone layer. In turn of this massive emissions, it traps more ultraviolet rays inside the earth; Continue reading...

Outline

Wind energy can be used as an alternative energy source but the question is whether it is really cheap, effective, and practical.
Science is of wind energy is by convention where cold air moves down and hot air up causing a cyclic motion that can drive turbines.
It is also very effective as remote and rural areas can be supplied with energy due to their vast land spaces.

Furthermore, it has no emissions hence does not lead to global warming and environmental pollution.

Major shortfall is that it is hard to be predicted by meteorologists making it highly Continue reading...

There is no doubt that the negative effects of non-renewable energy have increased the need to adopt policies that encourage wider utilization of renewable sources of energy. This can be in part due to the necessity of minimizing dramatic costs associated with advancement in technology and as well, in part due to the need to reduce carbon dioxide emissions (Gasch, and Twele 20). Similarly, the increasing global energy demands have also increased the attention given to non-renewable sources of energy. Among other sources, wind energy is among the leading sources of renewable energy. Being a clean natural resource, wind Continue reading...

Abstract

Saudi Arabia, one of the most developing countries in the world is gifted with massive natural resources, in the form of oil. It is the country which has actually made its GDP rise high because of exporting oil to other parts of the country. However, with the rise in demand for oil in the local market itself, it needs to decrease the overall oil export quantity. The increasing population has given a threatening alarm to the nation that very soon they will be facing the scenario of oil scarcity. This will hamper growth as well as exports of the Continue reading...

The past couple of centuries saw industry developed at a rapid pace especially following the Industrial Revolution when manual labor was rendered nearly useless when replaced with machines. In order for machines to operate at peak capacity, intense energy use was required. Little has changed over these two centuries in terms of high energy consumption, which has two negative implications. While the most abundant and extractable energy sources, oil, gas, and coal are exhaustible, which means they will run dry at some point in the future, especially seeing as how world population surplus is palpable these days. More importantly Continue reading...

Wind energy is developing more rapidly than any other type of alternative energy. This means that the amount of wind turbines in the world is significantly growing. The market growth rate of wind turbines in the world over the past few years is about 25-30%.
