The Pros and Cons of Fossil Fuels

The First Law of Thermodynamics, also referred to as the Law of Conservation of Energy, states that energy can no longer undergo creation, not destruction. With that, it can only undergo transformation or change from one state to another. The Second Law of Thermodynamics states that the entropy of any system that is isolated always undergoes an increase. At that point, the systems that are isolated undergo evolution toward the thermal equilibrium ( Ciocan, Tazerout, Prisecaru & Durastanti, 2015). The above two scientific laws apply to energy use, energy conversions, and the need for energy efficiency. In specific, the definitions of the laws depict given ambiguities that indicate their applications to disciplines of energy. The laws illustrate the activities of lighting efficiency and thermal conduction as the laws state ( Ciocan et al., 2015) . The use of energy in different disciplines has to fit either of the laws. In its conservation, it is easily converted to another form hence not created nor destroyed. The pros of fossil fuels are that they are well-developed and also, they are reliable and cheap. The energy used in the harnessing of the energy from fossil fuels is developed. The fuels are excellent types of fuel for usage for energy based on load. On the other hand, fossil fuels have got some disadvantages. The energy sources have contributed to global warming ( Ciocan et al., 2015) . It is important to consider the source that will not affect the environment due to the cases of global warming. Also, they are non-renewable, unsustainable, incentivized, and in many cases accidents. The energy source produces low pollution, the operating cost is low, they are reliable, have high proficiency than fossil fuels, and interestingly, renewable. On the other hand, the energy source has an impact on the environment, a problem when it comes to the disposal of radioactive waste, high cases of nuclear accidents, the high cost of production, the presence of uranium which is finite, and high militants target ( Ciocan et al., 2015) . Solar energy is naturally available. It is sustainable, low impact on the environment, and has an energy that is readily independent. On the other hand, it comprises some disadvantages. It is intermittency, hence can only be generated through sunshine. Also, it may take a significant amount of land, and their materials are scarce in supply ( Ciocan et al., 2015) . Wind power is a clean energy and has no fuel to drill, mine, frank, burn, or transport. The source is sustainable and renewable, the costs are low and they decrease with time, they have a domestic supply in abundance, free when the infrastructure is paid for, the low life cycle of the footprint for carbon, and is used for most of the places ( Ciocan et al., 2015) . On the other hand, it is unpredictable as the wind is unsteady and inconsistent, it is not cheap when compared with other sources of energy they pollute the environment as they produce noise, cases of wildlife impact, and localized impact on weather and temperatures at night-time. The energy is renewable, it is green, it is highly reliable, it has a high rate of flexibility, and it is much safe when compared with other sources. On the other hand, it has got consequences for the environment, it is quite expensive, its availability depends on the availability of water, and easily affected by limited reservoirs ( Ciocan et al., 2015) . The characteristics of algae make it be most competitive as a fuel source. It is the most environmentally friendly. The algae are small aquatic organisms that help in the conversion of sunlight into a form of energy and the storage is facilitated in a form of oil. The energy source is so convincing hence attracting more attention. Advantageously, the algae-based biofuels drop in replacement for liquid fuels that are based on petroleum. Also, the fuel is inherently renewable and it stands to be a reliable source. It absorbs the carbon dioxide in its growth, and the waste carbon dioxide and wastewater can be utilized as nutrients. After a clear comparison of the algae source energy with other sources, it is evident that the new source is attentive ( Ciocan et al., 2015) . The source has a higher energy per acre than the bio-fuels. The source is reliable as it can be grown in areas where other types of agriculture are not possible. The production process is recently scaling high and the benefits are evident. Conclusively, when selecting a source of energy, there are things to consider. Reliability, renewability, the power delivered, sustainability, and the effects on the environment should be considered. Recently, it is important to consider the source that will not affect the environment due to the cases of global warming. It is important to consider that to protect the future. Technology advances resonate the best energy source for replicative outcomes. The advantages and disadvantages should be tabled as well so that to come up with the best option.
