Introduction energy Alternatives Fracking energy Alternatives Fracking Introduction Energy Alternatives Fracking Energy Alternatives Fracking, or hydraulic fracturing, is a process used to extract natural gas from once unreachable shale rock layers deep in the earth. To release the natural gas, highly pressurized fracking fluids (water mixed with various chemicals and sand) are injected, via steel pipe, into the ground to create cracks or fractures. This releases gas that flows to the surface to be collected in wells. Environmental concerns associated with fracking include water use, toxic chemicals, health concerns, surface and ground water contamination, soil contamination, air quality, and waste disposal. One of the most important aspects of any energy policy is energy conservation.
As consumer demand for oil drops, prices decline; the time the oil can be relied on is extended. To help reduce oil use, government regulations, NHTSA (2014), have required greater fuel efficiency in cars through the creation of the Corporate Average Fuel Economy (CAFE) standards. Congress has also required the phasing out of incandescent light bulbs in favor of the more energy efficient compact fluorescent bulbs. Like many new technologies, the upside of the compact fluorescent's energy saving capacity is countered by the downside that compact fluorescents require the toxic chemical, mercury, for their production. There are many alternatives to using petroleum and coal for energy, but each comes with a unique set of problems.
Most new technologies, like solar and wind power, are very costly to start up. Nuclear energy has its own unique drawbacks. Using nuclear energy is attractive to many because the technology is already in place, and it can generate large amounts of electricity from one plant. But the risks associated with nuclear energy are high. For example, there is no current solution as to how to deal with nuclear waste.
No matter how carefully a nuclear plant is built and maintained, there is always the risk of an accident. Further, nuclear plants can also be a target for terrorist activity, and the nuclear waste can be used to power nuclear weapons. It is certain that we will see the emergence of new energy technology, but it seems unlikely at this point that there will be one simple answer. Wind, solar, and geothermal energy are useful in certain geographic areas, but it will take many different solutions to fulfill the energy demands of the worldwide population.
Paper For Above instruction
Renewable energy sources present both promising solutions and complex challenges in addressing global energy needs. Among these, solar energy has gained significant attention due to its abundant availability and technological advancements. This paper evaluates solar power's economic considerations, environmental benefits and downsides, health risks, and overall viability as a sustainable energy source.
Economic Considerations
The economic landscape of solar energy has evolved considerably over recent years. Initial installation costs for solar photovoltaic (PV) systems remain relatively high; however, the decreasing costs of photovoltaic panels and improvements in manufacturing efficiency have made solar power more economically viable (International Renewable Energy Agency [IRENA], 2020). The levelized cost of electricity (LCOE) for solar has declined substantially, often falling below traditional fossil fuels in many regions (Lazard, 2021). Nonetheless, upfront capital investment, including the costs of photovoltaic panels, inverters, and installation, can be prohibitive for individual consumers or smaller entities. Large-scale solar farms benefit from economies of scale, reducing per-unit costs substantially (Baker, 2019).
Additionally, government incentives and tax credits play a critical role in offsetting initial expenses. For example, solar investment tax credits in the United States have accelerated adoption (U.S. Department of Energy [DOE], 2021). Maintenance and operational costs for solar systems are relatively low, primarily involving cleaning and occasional component replacements, making solar energy financially attractive over its lifespan. Despite these positives, the intermittent nature of solar power requires storage solutions or complementary energy sources to ensure reliability, which can increase overall costs (Huang et al., 2018).
Environmental Benefits
Solar energy offers notable environmental advantages over conventional fossil fuels. It produces no greenhouse gas emissions during operation, thereby significantly reducing the carbon footprint associated with energy generation (IPCC, 2018). Solar panels do not emit air pollutants such as sulfur dioxide or nitrogen oxides, which contribute to smog and acid rain. Moreover, solar power generation requires minimal water compared to fossil fuel plants, alleviating pressure on water resources (Schaefer et al., 2019). The reduction of air pollution is particularly beneficial for urban areas suffering from smog and respiratory health issues, making solar power a crucial component in improving air quality.
Environmental Downsides
Despite its advantages, solar energy entails certain environmental downsides. Manufacturing photovoltaic panels involves the extraction of raw materials like silicon, aluminum, and rare earth metals, which can have ecological impacts from mining operations (Gartmann & Pohl, 2019). The production process also involves hazardous chemicals and significant energy consumption, which can offset some of the environmental benefits if not managed properly. Additionally, large-scale solar farms require extensive land use, which might lead to habitat disruption or loss of biodiversity, particularly if placed in ecologically sensitive areas (Dorahy et al., 2020). Decommissioning and recycling of solar panels pose further environmental challenges, as many contain toxic materials such as lead and cadmium, potentially contaminating soil and water if not properly handled (Tao et al., 2021).
Health Risks
The health risks associated with solar energy are relatively minimal compared to fossil fuels and nuclear power. The primary health concern revolves around the manufacturing process, where workers may be exposed to toxic chemicals and fine particulates involved in panel production. However, these risks are largely confined to manufacturing settings with proper safety protocols (Gartmann & Pohl, 2019). During operation, solar panels do not emit air pollutants, noise, or radiation, making them a safe choice for surrounding communities (Luthra & Khanduja, 2020). Challenges related to disposal and recycling of panels with hazardous materials require strict regulations, but overall, solar energy’s health footprint remains significantly lower than other energy sources.
Conclusion
In evaluating solar energy as a renewable resource, its economic viability is steadily improving, driven by technological advances and supportive policies. Environmentally, solar power offers substantial benefits, particularly in reducing greenhouse gases and air pollution. Nonetheless, considerations regarding resource extraction, land use, and waste management highlight the need for sustainable manufacturing and recycling practices. The health risks linked to solar are minimal, primarily limited to manufacturing phases. Overall, solar energy presents a promising avenue for sustainable development, provided that environmental and social concerns are managed appropriately. As technological innovation continues and costs decrease, solar energy is poised to play an integral role in meeting global energy demands while minimizing environmental and health impacts.
