Renewable Energy Thesis Statement – Unlike fossil fuels, which deplete slowly due to their unconventional nature, renewables can be easily replenished. Air is an inexhaustible resource because it is created by the daily heating and cooling of the earth by the sun. Hydropower is the main source of renewable energy in the world. It depends on the water cycle which includes rain or snow, river water, ground water and water vapour. Therefore, the water on Earth is constantly replenished by rain and snow.
Therefore, the water used to run the turbines can be reused to generate electricity. Renewable sources emit little or no greenhouse gases during energy production. Geothermal energy emits almost 50 times less carbon dioxide, nitrogen oxides and sulfur than conventional fossil fuel power plants. According to Jacqueline Longwith (“Renewable Energy”), wind turbines and solar photovoltaic cells can help reduce carbon dioxide emissions significantly. Hydroelectric plants are also non-polluting because they do not emit greenhouse gases or other pollutants during the generation of electricity.

The costs and financial risks associated with installing efficient wind turbines or biogas plants are high because the current demand for renewable energy in the market is insufficient. This makes such resources a difficult commodity to find, even for “green”-minded consumers. Also, renewable resources may be environmentally friendly, but there are no facilities to exploit them. For example, dams are required to generate hydroelectricity, which can have severe impacts on local wildlife. As reserves of crude oil, coal and natural gas are still high, conventional resources are cheaper than renewables.
They are the easiest resources to use, as well as the most effective; For example, all alternatives to gas in transportation are short-term or have very poor outcomes. Less competition means it’s easier for consumers to top-up, unlike renewables, which require you to find specialist service providers.
Most of the energy infrastructure in the industrial world is designed to run on fossil fuels. According to Andy Darvill’s Science website, non-renewable fossil fuels provide 66 percent of the world’s electricity, while meeting 95 percent of our total energy needs. This includes heat, transport and power generation. This existing infrastructure makes the use of fossil fuels much easier than renewable alternatives that require large initial investments. Photovoltaic solar cells or wind turbines, for example, cost a lot of money to install. But the current building can draw electricity from the grid and existing natural gas pipelines without any new equipment. Non-conventional energy sources are capable of generating a more stable power supply as long as their fuel lasts. Renewable energy sources can rely on erratic or less frequent conditions such as sunlight to generate solar power or wind to turn turbines.
A long-standing concern about the use of non-renewable resources is their unsustainability. Eventually, these limited resources will run out or become too difficult to mine, and our energy infrastructure will lack the fuel resources we need. Pollution from the mining, processing and consumption of these fuel sources is of great concern. Harmful levels of air pollution are caused by coal-fired power plants and energy generated by the combustion of petroleum products. Another concern when using this type of fuel is the possibility of an accident, which can destroy human lives and the environment. Although relatively rare, the consequences of an accident in a coal mine, oil mine, or nuclear reactor can be very serious. I believe renewables will be great for El Paso.
The reasons I support this are all the sunlight we have. El Paso could easily run its city on solar power. Also, you have a lot of free space to install solar panels, which will ultimately provide a huge space for energy storage. Since we are not near water and there is not much wind, we benefit from the sun. There will be some disadvantages, but they are outweighed by the advantages of solar power.

Health care, communication, mobility and many activities and services aimed at meeting even basic human needs cannot be accomplished without a secure energy supply. Hence, the energy sector is experiencing a boom these days, while fossil-based energy generation dominates the market. However, the extraction and burning of coal, oil and gas is associated with carbon dioxide (CO2) emissions and therefore contributes significantly to climate change (Owusu & Asumadu-Sarkodie 2016). As global energy demand is projected to increase by approximately 27% or 3,743 million tons of oil equivalent from 2017 to 2040 (Eule 2018), adverse environmental impacts of fossil extraction and use may intensify. It is clear that it is impossible to maintain energy security and environmental sustainability by continuing to use non-renewable energy sources. With this in mind, turning to alternative energy seems like a good solution.

“Alternative energy” refers to energy sources other than fossil fuels, including renewable sources such as solar and wind, as well as nuclear energy (Taylor n.d.). It is important to distinguish nuclear energy from other types of alternative energy sources because the former is produced using inorganic natural elements and is non-renewable. This presentation focuses primarily on renewable energy sources, considering the differences between them and the inherent risks of nuclear power generation.
Although the production of alternative energy will not solve all existing environmental problems, the transition to the global use of alternative energy will have a significant positive impact on the environment, mainly because power plants using renewable sources are associated with low CO2 emissions. Soil and water pollution and waste etc.
The transition to alternative energy can have a positive impact on the environment, mainly because energy plants using renewable sources emit less CO2 than fossil energy plants (Vezmar et al. 2014). In addition, renewable energy production is less harmful to water conservation than coal and other fossil fuel power plants and may be associated with lower levels of soil and water pollution (Tripathi et al. 2015). However, it must be said that the use of alternative energy sources does not solve all existing environmental problems. In this presentation I will outline some of the major controversies regarding the potential environmental impacts of renewable energy sources.
The diagram developed by Vezmar et al. (2014) showed that all plants producing energy using renewable sources emit less CO2 than fossil plants. Coal is the most polluting energy source, accounting for 900 kg/megawatt hour (MWh) of energy emissions, while wind energy, thermal energy and solar thermal energy are the least polluting forms of energy production, resulting in only 17, 14 and 12 kg/MWh, respectively. respectively. It is worth noting that although plants operating in photovoltaic (PV) systems cause some air pollution, the production of PV energy itself does not emit greenhouse gases and is very safe (Vezmar et al. 2014).
Data presented by Vezmar et al. (2014) explain that switching to alternative energies can help significantly reduce CO2 emissions because they are associated with less air pollution compared to shale gas, which is known to be the cleanest energy source among all fossil fuels.
According to Ted Trainor, “While previous figures are neither precise nor reliable, their magnitude suggests that the energy target of 1000 EJ/year for 2050 cannot be met from alternative energy sources within safe levels of greenhouse gas emissions. Such a goal cannot be achieved without changes” (Pike, 2017, paragraph 7).
However, with the expected substantial growth in world population and the resulting increase in energy demand, some experts and researchers do not believe that alternative energy will be a good solution. According to Australian academic and economic degradation advocate Ted Traynor, “the energy target of 1000 EJ/year for 2050 cannot be achieved from alternative energy sources within safe levels of greenhouse gas emissions” (Pike, 2017, para. 7) . This means that the global community is geared towards economic growth and continuous improvement
