Renewable Energy is a source of energy that is not depleted by use, such as water, wind, or solar power. The world currently relies heavily on coal, oil and natural gases for its energy. Fossil fuels are non-renewable, they draw a finite resource that will eventually deplete, becoming too expensive and too environmentally damaging to retrieve. Although many renewable energy resources like wind and solar energy are constantly renewed and will never run out. South Africa has a large abundance of coal and get 77% of it energy through coal and the remaining 28% is exported around the world. I think that the high percentage of coal that is exported is of a result of the country in need of funds and i think that the remaining 77% that is distributing through South Africa will not be enough as the demand for energy is growing by the day and its not going to stop growing. The coal that we burn to create energy is very bad for our environment as it releases carbon dioxide into our atmosphere and if we don't be careful our country might not be as beautiful in decades to come. Our country can depend on coal as our main source of energy but i do not think it is a viable option for the future as it is non-renewable and will eventually run out. Renewable energy is an option that South Africa needs to consider as it provides a source that our country can rely on forever. That is not the only benefit that it has as it provides an economically viable option as this project can create jobs and allow us to sell more of our coal to other countries who are short of coal. I think that because of these facts and benefits, renewable energy would solve a lot of South Africa’s problems.

Semantically fossil fuels are a renewable source of energy, however given that it takes millions of years for the organic materials to be broken down and converted, it is wholly unrealistic to consider them as renewable. As the demand for fossil fuels increases and source diminish faster than they are replentished, the United States must work towards a renewable energy independent state using truly renable sources, both technically and in practice. With changes in the home, as consumers in buying goods and with alternative fuel sources backed by public trust and governmental involvement, the United States could drastically lessen its dependence on fossil fuels, foreign and domestic.

Our country is currently suffering energy-wise, we have been powering with inefficient sources for years now and the harm that it is doing to the country has started to become apparent. Renewable energy is the only way to stop, or at the very least set back the inevitable downfall of our ecosystem. I think that the next big breakthrough for renewable energy is implementing off-grid communities that use renewable sources as their main sources of power, so that we can potentially escape the energy rut that we got ourselves stuck in.
The year is 2200. The world is going through a fossil fuel shortage. Oil reserves are almost completely consumed and it is becoming impossible to find new fossil fuel sources. Not prepared for this event to occur, The United States, has no alternative options. As a result of the oil shortage, the standard of living deteriorates. Heat in homes, supermarkets full of food, and transportation, all basic necessities taken for granted, will be depleted because fossil fuels are used to power almost everything. The key to the prevention of this future is renewable energy. Unfortunately the support for the use of renewable energy is weak and ineffective. Unless the US puts forth effort to research and promote the use of renewable energy to consumers, conversion from fossil fuels to renewable energy will no longer be an option.
Energy is the basic necessity of daily life. Nowadays, dependence on fossil fuels for energy needs becoming lower in numerous countries due to the potential of renewable energy to supply sustainable energy to the huge populations in many developing countries who are short of clean and continues energy. Generally, renewable energy can be defined as energy that is derived from natural resources which are constantly replenished and theoretically inexhaustible. Fossil fuels on the other hand can be described as energy that cannot be renewed and will eventually diminish. Thus, in many developing countries renewable energy is the alternative energy to replace non-renewable energy or commonly known as fossil fuels. In addition, according to Sorensen (2004), there is a greater demand for renewable energy sources nowadays due to the uncertainty of fuel price rise in living expenses. Commonly, there are many types of renewable energy available in our world such as wind power, biomass energy, solar energy, hydroelectric power and geothermal energy. However, the main three example of renewable energy are hydroelectric power, solar and biomass energy (Refer to Figure 1 in Appendix 1).
In the debate of traditional energy vs. renewable energy the clear winner is renewable energy. Renewable energy is vastly superior over traditional energy because it decreases dependence on foreign resources, produces no emissions, and is not limited in quantity. Opponents of renewable energy are likely to argue that this is not the case and that instead, traditional energy is better because it creates job growth, is reliable during all hours and climates, and comes with a lower cost. These advantages however are either misconstrued or hardly outweigh the long-term positive benefits of renewable energy.

The United States currently relies heavily on coal, oil, and natural gas for its energy. While the price of natural gas per barrel continues to plummet, the United States is constantly seeking new sources of renewable energy. Renewable energy consists of any type of natural resource (solar power, ocean power, wind power, rain, snow, etc.). that naturally and automatically replenishes itself. Renewable energy is important because it is infinite and everlasting, meaning our children and our children’s children will be able to utilize these resources long after we are gone.
“Is Renewable energy an economically viable option for South Africa?” “Renewable Energy is a source of energy that is not exhausted when used.” “Economical means giving good value in relation to the resources used or money spent.” “Viable means capable of working successfully; feasible.” (Soanes, Hawker & Elliot et al., 2005)
One of the most compelling arguments for the use of renewable energy is how many forms exist of it. Nuclear power, solar power, wind power, tidal power, hydroelectric power, pumped storage, wave power, geothermal power, biomass, and biogas are the most widely known renewable energy sources (Darvill, 2013). This large selection of fuels supports the idea of renewable fuels one day powering the entire planet. All the sources of energy have different niches and benefits. Solar energy is extremely effective when providing energy for small establishments such as a house or small store, but hydrothermal power would be a more plausible solution for factories or large establishments....
Why do we need to rely on renewable sources? Most of the energy that we use today comes from fossil fuels such as natural gas, coal, and oil. All of these resources are non-renewable, so you can finish one day. In order to have a better world and a healthy environment for the future, people are trying to obtain energy from natural resources instead of non-renewable sources. In the lecture “Renewable energy resources” (2014), Mistry focuses on some advantages and disadvantages of renewable energy.

With the depletion of fossil fuel resources comes speculations and debates about alternative energy sources. The world, including the Philippines, is practically dependent on a dwindling non-renewable source of energy. Today, experts are debating about and considering three options: Nuclear, Solar, or Wind Energy. Everyone has been accustomed to the bad image of nuclear energy as a result of the Chernobyl and Fukushima incidents above all others. The popular belief is that radiation from a nuclear meltdown is very harmful to humans and other living things—which is true—and that nuclear power plants are very dangerous and not ideal—which is not. According to Smith, et. al (n.d), all the nuclear disasters that ever occurred were caused by human error and natural disasters like tsunamis, not one because of system failure. Putting the false beliefs aside, with proper engineering and adequate maintenance by experts, a nuclear power plant is a very ideal and viable source of energy for the following reasons:

Using fossil fuels such as coal and oil is inefficient, dangerous, and otherwise a process that is known to eventually fail as a long lasting energy source. Yet, there is hope for the future of energy, this new hope has many shapes and forms, but requires a chance to be fully implemented in our everyday life. Such energy sources like solar energy, wind energy, geothermal energy, and hydro power are the key to our future. These energy sources are proven to be long lasting, safe, more reliable, and the next innovation. In short, all Americans should switch to renewable energy, resulting in a safer and more efficient world.
