Coal remains a source of energy for power generation to this day. Despite facing opposition from various quarters, its use continues.
At the same time, calls for renewable energy are growing as a means to generate clean energy for the future. Furthermore, coal supplies are projected to run out in the coming years.
Therefore, alternative energy sources are needed to meet future electricity demands. One such option is harnessing solar energy.
Coal Usage
Coal has long been used as a source for power generation. However, its use gives rise to several issues, as outlined below.
a. Environment
Coal is a fossil fuel that emits greenhouse gases, contributing to climate change. Coal-fired power plants are under pressure to mitigate their environmental impact, often facing pollution taxes.
b. Limited Resources
Coal is a non-renewable natural resource. This means its availability diminishes with use; the more frequently coal is consumed, the sooner it will be depleted.
c. Infrastructure
Many coal-fired power plants are experiencing declining efficiency due to aging. Investing in coal presents a dilemma, given that supplies will dwindle over time.
There is also the issue of the high initial costs associated with establishing coal-fired power plants.
Market Uncertainty
Market uncertainty surrounding coal-fired power plants arises from factors such as price fluctuations, pollution tax policies, and the transition toward renewable energy. These factors indirectly impact long-term business viability.
Solar Power Usage
Solar power is gaining popularity because it relies on sunlight—an inexhaustible energy source. However, implementing this system presents certain challenges.
a. Intermittency
Solar power generation is heavily dependent on sunlight. Cloudy weather, the rainy season, or any obstruction of sunlight can disrupt energy supply, thereby affecting the performance of the solar power system.
b. Costs
The initial installation of solar power plants remains expensive. This can hinder widespread adoption and prevents mass implementation.
c. Grid Integration
Solar power plants need to be integrated into the electrical grid, which presents both technical and policy challenges. Issues include grid stability, power output, and grid connection requirements, all of which can add to installation costs.
d. Energy Storage
Solar power systems generate electricity during the day when demand is low, and excess energy is fed back into the grid. Storing solar energy is challenging because it requires batteries, which inevitably increases costs.
Conclusion
Overall, solar power is far superior to coal. Emissions associated with solar power stem from the manufacturing of solar panels, yet these amounts are far lower than those produced by coal.
In recent years, the cost of solar power has become comparable to that of coal, dispelling the argument that solar power plants are too expensive for commercial energy needs.
Solar power is expected to replace coal-fired power plants, helping to reduce emissions and provide sustainable, clean energy for the future.
