As global energy consumption continues to rise and non-renewable energy sources are being depleted, efforts are being made to explore and utilise alternative energy sources. The utilisation of alternative energy sources can bring benefits but also poses challenges.
One of the main benefits of renewable energy is its sustainability, ensuring a continuous and unlimited source of energy. Additionally, renewable energy generates minimal to no waste that could harm the environment through pollution or other negative impacts.
Countries that incorporate renewable energy as an additional energy source are experiencing economic advantages, particularly in numerous rural areas. The majority of their initiatives are situated outside urban hubs and capital cities.
One general drawback of utilising renewable energy is the challenge of producing significant amounts of electricity comparable to traditional fossil fuels. Another prevalent issue with alternative energy sources is the dependability of the energy supply, as renewable energy generation is dependent on weather conditions.
One more downside of alternative energy sources is that the equipment required for energy generation tends to be relatively costly to install (initially).
Below are the various pros and cons of alternative energy sources.
• Solar energy is a valuable source of energy as it is both cost-effective and efficient. By harnessing the power of the sun, it is feasible to increase the use of solar energy as an alternative to conventional electricity. However, certain limitations exist, such as regions with high latitudes and areas with frequent rainfall, which may not be suitable for efficient solar energy production.
• Wind energy is an effective source of electricity. It has the potential to account for up to 20 percent of total electricity consumption in the future. Additionally, it is an environmentally friendly energy source as it does not produce any harmful gases during the energy conversion process. The location plays a crucial role in harnessing wind energy; areas with high latitudes and coastlines are ideal for setting up windmills. Moreover, a considerable land area is required to install an adequate number of windmills.
• Hydroelectric and tidal energy both derive from water sources. Hydroelectric energy is primarily generated through dams, while tidal energy harnesses the natural tides of the ocean. Utilising water for energy production is an environmentally friendly approach. Nevertheless, there are drawbacks to consider. The construction of river dams for hydroelectric power is costly, and tidal energy is reliant on the unpredictable nature of the ocean. Furthermore, tidal energy facilities are believed to have adverse impacts on migratory birds and fish populations.
• Biomass - this renewable energy source includes fermented animal waste, agricultural crops, grains, and other natural products. It can be utilised for alcohol production and to reduce the dependency on gasoline. By utilising waste materials, it serves as an alternative energy source, although it still emits greenhouse gases.
Despite having some drawbacks, alternative energy sources, being renewable, have disadvantages that are outweighed by the negative impacts of traditional fossil fuels.
By investing in renewable energy sources, you not only benefit the environment as a whole but also support the local community.
