Different activities in the society today require the use of energy. There are different energy sources in the world, but their sustainability is in question. One cannot avoid using energy in their daily activities, with the most commonly used energy being electricity. It is evident that electric energy has the majority of uses in the society, either domestic or commercial. The resolve of this thesis is to take an in-depth analysis of the alternative sources of energy and determining their sustainability. There are various dynamics to sustainability, the most common being renewability of the energy source. Electricity uses water but is not a sustainable source. This is because when the water reserve levels drop, there is scarcity in this form of energy. This paper seeks to analyze the different sources of energy and their level of sustainability relative to their uses.

Some of the most common sustainable alternative sources of energy include solar power, wing energy and thermodynamic power. Some of these energy sources remain vastly untapped because of the difficulty in accessibility and conversion of the raw energy into the energy for consumption by the society. There is a strong argument for sustainability of the different sources of energy mostly because they are renewable. Hybrid cars have recently gained popularity amongst the youth in the society because they are affordable and they do not depend on the non- renewable energy source that is gasoline and petroleum. They run on electricity, a sustainable energy source because there will always be ways to produce it (Tester, 56).

Wind and solar energy are naturally occurring energies, therefore, their sustainability is guaranteed. The use of these energies ensures that individuals will use up to 1/20 of the energy that was consumed over two decades ago (United Nations). Sustainability aims at reducing the energy consumption and increasing the accessibility of the new energy sources. Renewable energy is sustainable because there is no end to the naturally occurring forces of nature. Today, there is only a limited amount of fossil fuels such as coal, natural gas and oil. Their existence and use is limited hence they cannot be categorized as sustainable.

Overreliance on coal, natural gas and oil is unsustainable because it leads to depletion of the amount available for use by future generations. Once these reserves and resources are used up, there is no other way of producing them. This is because they are not naturally occurring in nature. If the events of the recent past are anything to go b, sustainable energy is the fuel of future generations. This is the age of new energy. Coal, natural gas and oil are some of the non-renewable energy sources. One of the reasons they are unsustainable is the amount of pollution they cause in nature. They are non-environmentally friendly due to the gases and fumes they produce in the atmosphere. Renewable energy sources are not pollutants, and they do not emit any toxic gases and fumes (Sioshansi, 27-28)

Majority of the energy sources used today were undiscovered two decades ago. If they were discovered, there was no way of tapping into them yet.  Instead of using electricity in households and other small scale plants that need minimal amounts of energy, they could have shingled and panels for the conversion of solar energy into power. They are sustainable mostly because there are minimal costs for the solar panel and installation charges. This leaves the household financially sustainably by freeing them of the monthly electricity bill.

Windmills have also grown to be a popular occurrence in the society because wind energy remains untapped and unused in modern day society. Similar to solar energy, the sustainability of with energy is pegged on the fact that it is renewable and finds its use across a large pool of uses. There are different ways to use solar energy, most of which are diverse. New and renewable energy sources are found in water, wing and solar. They have no pollution, and dissimilar to oil, coal and natural gas, are renewable. With time and the effects of population pressure, earth will run out of non-renewable energy sources, leaving the generations of the time relying on naturally occurring energy sources (Orr, Bent and Baker, 156-158).

Sustainability means that the society has to meet their energy needs by reducing their reliance on non-renewable energy sources, and shifting their focus towards the renewable energy sources. Renewable energy sources are those sources whose supply will never deplete. This means that nature finds a way of reproducing them. Other renewable energy sources include energy efficiency, geothermal energy, biomass, hydroelectric power and water energy. Pollutants from the naturally occurring energy sources have led to global warming, a phenomenon that threatens the earth’s atmosphere and environment (Tester, 87). The sustainability of the renewable energy sources ensures that there are no pollutants from these sources, and the effects of global warming are reduced, if not eliminated.

Society today is changing the ways and manner with which it uses energy by using less of it. There is a development of new and sustainable energy tools that aid in the reduction of the quantity of energy consumed. A typical example is the florescent bulb that uses only a quarter of the energy used by a normal bulb. Windmills produce energy at a lesser cost than burning coal. Solar panels make electricity directly from energy, dissimilar to water which has to go through different stages before it can finally be transmitted as electricity.  Efficiency in the energy sector and production of clean energy is one of the measures of ensuring sustainability in the energy sector.
