World’s Alternative Energy Sources

gdfgAlternative energy sources; also known as green energy, are renewable energy sources that can be replenished at a comparable to the rate of consumption: This means that renewable energy sources are at no risk of getting completely depleted in the near future; as compared to non-renewable resources. As the global population increases, the world’s energy consumption is rising every day. The rise in world’s energy consumption has a direct impact on the available energy resources; especially non-renewable energy sources such as coal, oil, and natural gas; which are the world’s primary energy supplier today.

Today; non-renewable energy sources face a strong opposition from environmental policy makers across the world, due to negative impacts they impose on the environment. Coal, oil, and natural gas; also known as fossils, are associated with production of dangerous natural gases such as carbon dioxide and nitrogen that are causing significant rise in global temperatures.

Consequently; governments, environmental policy makers, and investors across the world are working extra hard to control the global temperatures; by promoting green energy technologies such as wind energy, solar energy, and hydro power: These renewable energy sources have several advantages over fossils; which are not environmentally friendly and are also expected to get exhausted in the foreseeable future because they cannot replenish.
Major Alternative Energy Sources.
solar-energy1. Solar Energy.
Solar energy is energy generated from the sun. Solar energy is one of the most recommended green energy technologies due to a number of factors: To begin, solar energy widely available and it is free to use once the energy converting technologies like solar panels are in place. On the other hand; solar energy imposes no environmental dangers to the habitats of the earth, since its production is not associated with emission of natural gases such as carbon dioxide and nitrogen. Besides; solar energy technologies need trained technicians to operate and run them; this means that apart from being environmentally friendly, solar energy also boosts the global economy by providing employment.

Solar panels are the most common technologies that Home owners and businesses use to generate solar energy. Once the solar panel is installed, solar energy will be automatically transformed into useful form. PV, or photovoltaic cell is the technology used to convert the solar energy into heat and electricity. Solar panels come in different sizes and capacity; and there are a number of factors that need to be considered before purchasing a solar panel as follows:

– Cost: Cost of the solar panel is among the most important things to consider. Depending on your energy requirements; compare prices offered at different online stores such as Amazon and select the one with the price that fits your budget, and at the same time will satisfy your energy needs.

– Rated Watts: You need to consider the number of watts a given solar panel will be able to supply once you purchase and install it to generate power. The wattage of a solar panel is directly proportional to the power that it will generate; such that a 200 wattage solar panel will produce the same 200 watts per hour. After estimating your power needs and you have the estimate amount of power that you need, you should be able to select the solar panel with right wattage for you.

– Solar Cells: Solar panels are made of different solar cells; and one needs to be sure which solar cells are used on a given solar panel. The two types of solar cells are Monocrystalline and Polycrystalline cells; monocrystalline solar panels are made of a single large cell module, while polycrystalline solar cells are made of several adjustable cell modules. Polycrystalline solar panels are always larger in size and also in wattage rating; making it a superior choice over the monocrystalline solar panels depending on your energy needs.

– Durability: Durability is yet another important deciding factor that must be put into consideration when buying a solar panel. Ensure that the solar panel you select to buy has a longer warranty period of 25 years or more. The durability of a solar panel largely depends on its manufacturer: Make certain that you only purchase solar panels from recognized dealers and manufacturers who have quality and original solar panels.

– Tolerance and the Efficiency of the Panel: Solar panels have different efficiency and tolerance: A solar panel tolerance is the accuracy of a solar panel, or a degree to which a given solar panel will provide power according to the rated power. Most poor quality solar panels are overrated and will not provide the amount of power it is rated. Ensure that if a solar panel is rated 100 watts; it will be able to provide that amount of wattage per hour once it is installed.

– Temperature Co-efficiency: Solar panel coefficient rating is among the very important factors to consider, since it will determine how poor or effective your solar panel will behave with changing temperatures. Some poor quality solar panels are known to respond negatively when exposed to too much heat. A good co-efficiency rating will be lower per degree Celsius; the lower the co-efficiency rating in percentage, the better the solar panel.

wind-power2. Wind Power.
Wind power is yet another important green energy technology that is strongly supported by investors, governments and environmental policy makers. Wind energy has several merits over non-renewable energy sources such as coal and natural gases. Wind energy is a green energy power source since it is not associated with dangerous natural gases that is causing global warming; which has remained among the major environmental issue for a long period of time.

Wind energy technology is an economic booster since trained professionals are employed to maintain the machines and other technologies related to wind power generation. Besides; wind power fields can also be used for different purposes such as grazing grounds and farming fields to support the economy of the areas where they are installed.

Moreover; energy companies are today emerging with the latest wind turbine technologies that have much higher efficiencies and capacities; and the future of wind energy as an alternative power source is very promising. Like solar panels; wind turbines are available in different prices; sizes, capacity and efficiency. You need to research and find the best wind turbine company with quality turbines that will last and be efficient in providing the estimated power once installed.

Alternative Energy Source Pros and Cons3. Other Alternative Energy sources.
Apart from solar and wind energy sources as the major green energies; there are a couple of other alternative energy sources; namely hydro-electric power, geothermal power, and biomass energy. These energy sources are renewable and are classified among the green technologies that are recommended to help control the global temperature issues.

Hydro-electric Energy.
This is energy or power generated from water sources, including rivers and dams. Like wind power, hydro-electric power uses turbines to convert energy into electricity. Wind turbines come in different sizes and capacity depending on the amount of energy needed from a hydro-electric power source.

However, as much as hydro energy is considered a green power technology, it faces criticism since it interferes with aquatic life: The water turbines used to generate power may kill aquatic animals and plants that are useful for the ecosystem. Besides; the cost of setting up these turbines is always high due the high installation cost of the hydro-power dams and strong water source. Moreover, hydro power can only be used easily in areas with moving water sources such as waterfalls and rivers; which are not easily available or accessible  in some regions or countries.

Geothermal Power.

Geothermal power is another source of alternative energy; which is developing at a very significant rate in some countries around the world. This source of energy is a considered a green energy source too, since it has no emission of natural gases that cause temperature changes. Geothermal is readily available and is free to use like other alternative energy sources; and as the technology advances in efficiency, it may soon become a major energy supplier in some countries where geothermal energy is widely available.

Biomass Energy.
Biomass energy is yet another green energy technology that is gradually becoming popular due to its availability: Bio energy is produced animals and plants waste or remains. This means that this alternative energy source is widely available and free to use. Many homes are today utilizing bio-energy to produce electricity in a similar way fossils produces energy; however, the amount of green gas emission of this energy source is much less as compared to fossils and that is why it is considered a green energy technology.

Non-renewable vs Alternative Energy Sources: Why Alternative Energy?
Ideally; non-renewable energy sources such as oil, coal, and natural gas are the major world energy suppliers today: Due to the fact that these fossil fuels are not renewable; this has caused a big fear in the world as a whole since they are expected to come out of supply in some years to come. However, this should not be the main concern as fossils are still abundant: The following are the primary factors to consider when compare non-renewable and alternative energy sources.

1. Production and Other Costs.
Among the major things to consider when evaluating energy sources is the general cost associated with the energy sources: Fossils or non-renewable energy sources are known to be very costly to set up. Firstly, fossils are associated with extraction costs that are incurred when drilling energy resources such oil and coal from beneath the ground. Secondly; fossils are also associated with transportation costs that are incurred when transporting crude resources to the manufacturing sites. Finally; since the overall cost of producing non-renewable energy is always high; the consumption cost will be high in order to off-set the costs incurred in the production.

Alternative energy sources such as solar, wind, and hydro powers are considered the most cost effective energy resources due to the low cost of production: These energy sources are not associated with extraction, transportation and other costs associated with fossils. Consequently; alternative energy sources are always affordable for the consumers.

2. Efficiency.
Efficiency of an energy source is another important factor to consider. Although non-renewable energy sources are still more efficient than alternative sources; the efficiency of alternative energy sources such as solar power and wind power is increasing significantly. The latest emerging alternative energy technologies are improved, and a solar panel or wind turbine efficiency is no longer a factor that hinders the development of these renewable energy sources.

3. The Environmental Factors.
The environment is also a very vital factor that must be considered when evaluating energy sources: Since the global temperature has remained an issue for several years without clear solutions to help control it; alternative energy sources that are considered green power sources need to be utilized to the maximum. Green energy sources are always associated with little or no emission of dangerous natural gases that degrade the environment by raising the global temperature and sea levels.

Transportation of fossils such as oil through water may cause water pollution due to spills and consequently interfere with the lives of aquatic animals and plants. Moreover; drilling fossils beneath the ground has soil erosion and land deformation in some areas; causing wastage of useful lands that could have been used for something else. As such; alternative energy sources are recommended due to their environment friendly nature.

alterConclusion.
Due to the cost effectiveness of alternative energy sources such as solar and wind powers; governments, environmental policy makers and investors across the world need to play their respective roles; to ensure that common citizens can access and use easily available alternative energy sources. Besides, with the rapid growth of green technologies, the efficiency of wind and solar powers are expected to increase and compare to the efficiency of fossils such as oil and coal among others.

Also on the plus side; alternative energy sources are considered a green technology and do not impose lots of environmental threats such as global warming and rising sea levels; which is the case with fossils or non-renewable energy sources. Finally; alternative energy sources are world economy boosters, and they provide employment to the citizens of the countries where they are available, to run and maintain energy generating machines.
