The alternative energy source should enable humans to reduce carbon dioxide emissions. The energy sources should be capable of meeting the energy needs of the current society without compromising the needs of the future generations. Additionally, the sources should be cheaper than the existing sources to reduce the cost of production that industries have to undergo. This paper focuses on identifying potential alternative energy sources, which can be used to substitute fossil fuels in the future. Currently, there are quite a number of energy sources. However, humans have not maximized their utilization. Fossil fuels are the most exploited sources of energy. However, these energy sources are disadvantageous since they lead to excessive pollution of the environment. Additionally they have other negative impacts such as increasing global warming since they emit greenhouse gases. Moreover, the fossil fuels may become depleted in future since they are being utilized rapidly. Other alternative energy sources that humans should consider exploiting in future include thorium, solar energy, hydropower, wind energy, geothermal energy, biomass, and nuclear energy (Ayres & Ayres, 2010). Solar power is derived through transformation of sunlight in electricity. The conversion process makes use of photovoltaic as well as heat engines. Solar power is increasingly becoming a popular source of energy due to its efficiency and transportability. Additionally, solar energy is inexhaustible hence affordable source

of energy. Utilizing solar power will result in reduced pollution in addition to reducing energy related conflicts. However, solar power is disadvantageous since sunlight can only be harvested when it is sunny. Additionally, it must be stored for usage in times when it is cloudy such as during winter. There are limited technologies for energy storage, which makes it hard to invest on solar power (Ayres & Ayres, 2010). Wind energy is another energy source that is considered sustainable. Wind power is generated through harnessing of wind and converting it to electricity. Wind power is capable of meeting the global energy needs. However, most countries have invested less on harnessing of wind power. Therefore, wind power is a possible alternative to fossil fuels. The advantages of investing in use of wind power include its renewability, its plentiful, its usage does not lead to environmental pollution or global warming, and it is widely distributed hence easy and cheap to produce. The main disadvantage of harnessing wind power for energy generation is that the turbines produce a lot of noise leading to noise pollution (Ayres & Ayres, 2010). Hydroelectricity is another possible source of energy. Hydroelectricity comprises of power generated through harnessing the energy of falling water. Hydroelectricity is generated in hydro power plants and the process results in no direct waste. It is thus appropriate since it encourages environmental conservation. However, water resources are limited thus enough hydroelectric power stations cannot be constructed (Morgan, 2009). Geothermal energy is another alternative energy that can be used to replace fossil fuels. To produce geothermal energy, renewable heat is extracted from the earth and use to create electricity. Investing in geothermal energy would advantageous because geothermal power is reliable, sustainable, and cheap to generate. Additionally, geothermal power is environmentally friendly. Although drilling to trap
