For any society to survive in an effective manner, it needs two fundamental, natural resources. These resources are fresh water and energy. According to Black and Flared (2010), a normal human being may never survive if the body lacks water for a few days. The existence of energy in the universe takes many forms. This includes gasoline used to fuel a car, sunshine for growth of human and animal plants, and electricity that finds application as a source of power in most of the industries. As such, without energy, human beings would starve and consequently their bodies would stop functioning (Black, & Flared, 2010). Utilization of this energy costs money. There is a need of adopting effective measures that would safeguard from prevalence of an energy crisis, as a result of increment in the cost of energy.

Challenges experienced in the supply and demand of energy, in general, and considering fossil energy source, in particular, are many (Simon, 2007). These challenges include the effect of energy on the environment, and cost of energy. To overcome the challenges, there is a need of adopting alternative energy strategies. In addition, adoption of green building leads to a reduction of the energy consumption levels.

Term Definition

Alternative energy depicts all kinds of energy used in place of coal, fossil fuels, and natural gas. Alternative energy incorporates renewable energy. Renewable energy refers to energy sources, which find regeneration from natural process that, occur in the universe. Alternative energy sources include solar energy, biomass energy, energy from methane gas, wind power energy, geothermal energy, and hydroelectric power energy (Simon, 2007).

Energy Forms

The sun is the key source of energy. Energy from the sun finds absorption by the plants. Consumption of plants parts disseminates this energy to the human body. The plant energy may also find use directly through conversion into the form of ethanol. Living plants and tiny organisms acts as the major sources of fossil fuels. Fossil fuels include coal, natural gas, and oil, and they form part of the nonrenewable energy found in planet earth. Forms of renewable energy include solar energy, geothermal energy, and wind energy. These forms of energy have the ability of regenerating themselves in a rate equivalent to the extraction rate.

Reasons for Alternative Energy

The global supply of nonrenewable energy is facing circumstances of depletion of the energy source. The nonrenewable energy facing depletion includes oil, natural gas, and coal. Despite the fact that nuclear energy is available, the use of the energy is too dangerous. According to Simon (2007), it does not matter the degree of research that will aid in refilling the reserves of nonrenewable energy, shortfalls on demand and supply of energy will occur. He further claims that the consumption rate of energy exceeds the number of available reserves, or additional reserve discoveries. As such, without an alternative energy source, energy crisis will emerge in the universe. This depicts that there is a need of exploring possible alternative energy sources, to safeguard the future industrial and commercial sectors.

The existing nonrenewable energy (oil and natural gas) have a characteristic of environmental pollution. This results in altering the ecosystem and affects fauna and flora directly. In addition, the wastes from these energy sources find their way to the atmosphere where they contribute significantly to global warming. This has side effects of changing the climatic patterns of planet earth. Moreover, the wastes are effective agents of air pollution. Therefore, in order to limit these side effects of nonrenewable energy, there is a need to shift to other alternatives for energy sources.

According to Simon (2007), alternative energy is a key contributor to promotion of economic and social justice. This also includes promotion of the development of an energy independent universe. This provides a normative answer to the need of adopting alternative energy sources.

Overview and Types of Renewable Alternative Energy

Alternative energy sources have a characterization of development as the technology sector appreciates a myriad of dynamics. The changes in level of technology globally have led to discovery of these energy sources that remained undiscovered for a long period. The alternative energy sources represent future expectations of the global energy. However, most people have not yet discovered the alternative forms of energy. Nevertheless, as the technology level changes and globalization take place, people will appreciate the alternative forms of energy.

The cost of alternative energy has an element of affordability. Considering alternative energy sources such as solar and wind, the cost associated with the use of these types of energy are relatively small in comparison to cost of use of fossil fuels. This result in adoption, in the use of alternative energy sources since they are economically feasible. Consequently, the demand for alternative energy has increased globally (Simon, 2007).

Simon (2007) claim that, in many regions, in the universe, the government provides tax incentives and grants to aid producers of alternative energy sell the energy in power grid. This makes many individuals venture in alternative energy as a form of business. The result of this is extensive innovation and development of alternative energy. This has also led to the emergence of firms that concentrate on producing or manufacturing alternative sources of energy. The firms have further established a competitive environment for their individual alternative energy. However, this has benefitted the public since these firms carry out extensive advertising. Therefore, the public gets the information with regard to alternative energy.

Solar Energy

Solar energy has source from the sun. The energy harnessing occurs via the use of solar collector cells or solar cells. The harnessing process of sunlight is quite easy and free. However, for large-scale energy plants, the harnessing of sunlight is quite difficult. The harnessing of solar energy finds application in generation of electricity in homes. With regard to cost of solar energy, the cost has proved affordability level since it involves acquirement of the solar panels and installation. Solar energy has received global acceptance as a “green future” since the energy is environmentally friendly and has no pollution effects to the environment.

The most common technologies of solar energy include solar thermal, silicon, and thin-film. These technologies produce solar panels, which appear in the market in different sizes. These sizes of the solar panels have different solar energy harnessing capacities, as well as the rate of electrical energy generation potential. Thus, individuals choose the solar panels based on the amount of electrical energy they desire to generate for their homes.

However, solar energy has inherent limitations. The material used in the manufacture of solar panels, for example, tin oxide (SnO2) has a significant effect in contamination of water and soil. Tin oxide finds application in the manufacture of solar panels in production of electron collector grids. Installation of solar energy systems that need use of concrete footings results in land clearing. This has side effects distracting the native plants and animals of their natural setting. Finally, solar collectors of most systems trap dust and any other kind of dirt, which minimizes the area of solar collectors exposed to the sun. This results into collection of a limited amount of solar energy. Consequently, cleaning of the solar collectors takes place with the use of industrial solvent cleaners or water. The products of cleaning have the side effect of destroying native streams through contamination. In addition, the soil receives a considerable amount of contamination from these products.

Wind Energy

Simon (2007) argues that wind energy is probably as old as the discovery of the wheel during the era of the agricultural revolution. Wind energy calls for use of blades to make propellers that collect the energy in a rotary motion. Despite the fact that wind energy has vulnerability to changes in weather conditions, the alternative energy source has proved feasible globally. Some areas, such as high altitudes on the land mass and coastal offshore in the oceans, experience a steady flow of wind. Therefore, these locations depict areas that need exploitation to harness the wind energy. The harnessing process of the wind occurs through the installation of wind turbines, which receive a rotary motion from the wind in order to generate electrical energy. Wind turbines installations may take the form of small homes windmills or commercial windmills. In commercial windmill, numerous-wind turbines find installation in a central place and results, in development of a wind plant. The wind plant then generates electricity sold to the national grid of a given region, in order for the electrical energy to reach the esteemed consumers.

Although, wind energy falls in the category of alternative energy, the energy poses a potential environmental damage. This environmental comes in the form of noise and visual pollution. In noise pollution, wind energy systems impair the comfort of both human beings and animals within the area in which wind generation systems installation has taken place. The noise has side effects of leading to relocation of the native animals. Consequently, the nature cycle of new locations and abandoned locations of the animals receives a myriad of dynamics. In addition, a conflict develops between animals and human beings on location habituating. On the other hand, visual pollution affects the sight of an individual. This occurs is situations in which the wind carries with it dust, or the wind velocity is too high for the normal human eyesight to withstand.

Geothermal Energy

Geothermal energy makes use of earth’s internally generated heat to produce energy. In the earth mantle, there are superheated elements such as iron. The means in which the superheated heat finds a way to the earth’s surface has variability, due to variability of the structure of the earth’s crust in many geographical locations,. In some regions, the molten material of the earth’s crust finds way to locations near ground water supplies. This result in drilling of wells to extract geothermal steam or water produced as a result of contact between the molten material from the earth’s crust and the ground water supply. The geothermal products extracted find use in running high-efficiency turbines, which aid in producing electrical energy. The geothermal product after running the turbine, finds its way into a rejection aquifer, which has proximity to the location of the geothermal extraction well (Simon, 2007).

The grading of geothermal energy resources takes into consideration the size of the geothermal locality and temperature obtained from the extracted geothermal products. Simon (2007) claims that geothermal products temperatures of above 200oC represent high-grade resource, 150-200oC medium grade resource, and 100-150oC low-grade resource. However, geothermal products may exhibit high temperatures up to 700oC. Heat exchangers find application in the installed system of geothermal energy generation, due to this high-temperature generation in geothermal energy resource;. The heat exchangers make use of low-boiling temperature fluids. These fluids exist as gases in room temperature. The fluids include pentane (boiling temperature of 36.1oC) and butane (boiling temperature of -1oC). As such, altering of these process conditions in a geothermal plant results, in a tremendous effect on heat transfer and turbine operation.

Geothermal plants have potential of environmental pollution. This pollution occurs through the process of airborne emissions. The gases emitted include hydrogen sulfide, carbon dioxide, methane, toxic sludge, and ammonia. These emissions occur in situations in which the geothermal plant makes use of open-loop system. However, the emission problem minimization occurs through adoption of a closed-loop system. In a closed-loop, the byproducts of geothermal process remain within the piping system of the plant, and there are no products, which find their way to the atmosphere or ground water. Geothermal resource plant location presents another key potential issue of concern. This occurs since the plant location may occupy public parcels of land or environmentally sensitive areas.

Hydroelectricity Energy

Hydroelectricity energy depicts energy withdrawn from natural waters in the rivers. Water dams find an establishment in the proximity of rivers. The dams get water from the rivers, which find application in rotating high-speed turbines located in the basement of the dam. The rotating turbines then generate electrical energy sold to the grid system for distribution to consumers.

Hydroelectric energy generation has advantages of not polluting the environment, and being a clean source of energy. However, the energy has a limitation of depletion of water levels in the rivers as a result of global warming. In addition, most of industrial firms damp waste products in the rivers. This result in a reduction of water level in the rivers and affecting the quality of hydroelectric energy generated.

Tidal Energy

Tides and waves in the ocean present an alternative form of energy that needs effective exploitation. The energy source is free and clean. Therefore, there are no possibilities of environmental pollution from the energy source. Tidal energy extraction takes place at the instance a tide flows through a turbine. The turbine rotates and consequently generates electrical energy, which finds its way to the national electrical grid system. On the other hand, wave energy capturing occurs through use equipments to trap waves. The equipment in turn, converts the waves into electrical energy. In general, oceanic energy presents an alternative source of energy that needs exploitation. Apart from tidal and wave energy, there is a need of focusing into the possibility energy generation from the oceanic water salt and ocean water temperature.


Biodiesel acts as a replacement of petroleum-based diesel. Virgin seed oils, vegetables and animal fats, or used cooking grease act as sources of biodiesel energy. The energy has low-emission and finds application in all standard engines with no side effects of power reduction capacity. The energy source is quite cost effective.

Biomass Energy

Biomass energy depicts energy derived from all forms of organic biological matter. Biomass includes plant material parts or fecal wastes from animals and human beings. Production of energy from biomass provides a clean way generating energy that has no effects of environmental pollution. The method cleans the environment since what would have been waste ends up a being energy. The cost for this method of energy generation has proved affordable since the raw materials have wide availability in the universe.

Hydrogen Energy

Hydrogen has proved to be a significant source of fuel. In this, hydrogen, fuel finds application in running cars. Hydrogen fuel has minimal environmental pollution effects and acts as an agent of establishing a “green future”. The technology involved makes use of a chemical reaction between oxygen and hydrogen to generate electricity. The byproduct produced from the chemical reaction is water. However, hydrogen energy has a limitation the limitation of the cost incurred in the production process of the fuel from hydrogen.

Alternative Energy for Oil and Natural Gas

The alternative sources for energy for the oil and natural gas that have exhibited a possibility of depletion include sand and shale oil, and coal bed methane. Oil sand demonstrates a type of sand in which oil extraction has a possibility. Shale oil represents the form of energy in which the shale produces oil after pressing.

Perceptions on Alternative Energy

According to Simon (2007), the public supports venturing into alternative sources of energy since the public see all the alternative energy sources as viable means for attaining energy independence. The public knows the cost associated with alternative energy. Consequently, many people have a desire to pay for the cost in order to attain independence in the energy sector. In addition, the public evaluates the available energy, not based on the cost of energy, but on the availability and “greenness” of the energy. In general, alternative energy gains support globally with a view that is “green” and safe.

Correlation Between Alternative Energy and Green Building

Green building depicts an area of adopting measures that lead to the establishment of environment-friendly system. Green building calls for erection of energy efficient and environmentally sound buildings. This occurs through the installation of heat insulating devices in the buildings and use of electrical appliances and structural elements, which are electrically efficient. Green building contributes effectively in the reduction of energy consumption levels.


Alternative energy depicts a measure that needs adoption in order to safeguard a region from side effects of possible energy crisis. This occurs since the nonrenewable energy sources are depleted throughout. The cost for adoption of alternative energy sources is quite high. However, the result of adoption of alternative energy is outstanding energy independence. Most people globally have proved to understand the benefits of alternative energy. Consequently, most people have proved ready to pay for the cost of alternative energy in order to attain energy independence. Green building is not a form of energy, but it acts as an effective means of reducing energy consumption rate and at the same time creating a clean environment. In general, alternative energy is a basic need in meeting the global energy demand level.
