What You'll Learn
Solar power is a renewable energy source
Solar power is a clean and environmentally friendly energy source. It produces little to no emissions during the electricity generation process, in stark contrast to coal-fired power, which releases large amounts of carbon dioxide and other harmful pollutants. Solar power has a significantly smaller carbon footprint than coal over its entire life cycle, even when considering the emissions associated with the manufacturing and disposal of solar panels.
The renewable nature of solar energy also means that it does not contribute to the depletion of natural resources. Coal mining, on the other hand, leads to land degradation, water pollution, and social and health issues for local communities. Additionally, the process of extracting and burning coal causes substantial environmental degradation.
Solar power has become increasingly cost-effective over the years, with manufacturing costs decreasing significantly. The decentralised nature of solar power systems allows for installation on rooftops, in remote areas, or even on mobile platforms, reducing the need for extensive transmission infrastructure. While solar power currently has lower energy density and reliability compared to coal, advancements in solar technology are continuously being made to improve efficiency and accessibility.
In summary, solar power is a renewable energy source that offers a clean, sustainable, and cost-effective alternative to coal. With its minimal environmental impact, infinite resource availability, and decreasing costs, solar power is an attractive option for a world seeking to reduce its dependence on non-renewable fossil fuels.

Coal mining has negative social and health impacts
Solar power is a clean, renewable energy source with minimal environmental impact. In contrast, coal mining can have severe negative social and health impacts on local communities.
Firstly, coal mining can lead to the displacement of local communities. The process of establishing mining sites often involves significant construction, deforestation, and the destruction of wildlife habitats and biodiversity. This can force communities to leave their homes and lose access to clean water and land, causing social unrest and hardship.
Secondly, coal mining can cause pollution and health issues for workers and nearby residents. Mining operations produce toxic waste and release pollutants into the atmosphere, including heavy metals and carbon. This pollution contaminates water and air sources, leading to increased health problems for surrounding communities.
Thirdly, the transient male workforce associated with coal mining can lead to social issues in local communities, such as increased alcohol consumption, violence, and the presence of sex workers. This can further impact the health and safety of women and families in these communities.
Additionally, coal mining can cause land degradation and soil erosion, undermining women's ability to provide food and clean water for their families and increasing their workload.
The negative social and health impacts of coal mining are well-documented, and the core issues appear to be universally consistent. These impacts are exacerbated when mining companies do not consult with local communities or respect human rights and abide by regulations. While coal mining can provide economic benefits and employment opportunities, these do not offset the potential negative consequences for the health and well-being of affected communities.

Solar energy is more environmentally friendly
Solar energy has a significantly lower environmental impact than coal. Solar panels generate electricity without emitting greenhouse gases, and their manufacturing and disposal processes produce minuscule emissions compared to coal. Solar power is approximately 20 times more environmentally friendly per kilowatt-hour (kWh) generated than coal, which releases pollutants like heavy metals and requires around 700 grams of fuel per kWh.
The environmental benefits of solar energy are further enhanced by its cost-effectiveness. Solar power systems have low operating costs and require minimal maintenance once installed, generating electricity for decades. Technological advancements have also improved the efficiency and affordability of solar panels, making solar energy a viable alternative to coal.
While solar energy has lower energy density and reliability issues due to weather conditions and storage needs, its environmental advantages are undeniable. Solar power represents a clean, sustainable choice, minimising land degradation, water pollution, and harmful emissions associated with coal.
Additionally, solar energy does not cause the same social and health impacts as coal mining, which can include displacement, pollution, and health issues for local communities and workers. Solar power's ability to be installed in various locations reduces the need for extensive transmission infrastructure, further decreasing its environmental footprint. Overall, solar energy is a much greener option than coal, offering a cleaner and more sustainable future.

Solar power has lower installation and maintenance costs
Solar power has become increasingly cost-effective over the years, with installation and manufacturing costs decreasing significantly. This has made solar power more accessible and a viable alternative to coal. Solar panels are easy to install on rooftops or ground mounts, and they harness an already-available resource—sunlight. This decentralised nature of solar power systems means they can be set up in various locations, including remote areas, providing energy access to a wide range of places.
The cost-effectiveness of solar power is further enhanced by its minimal operating costs. Once solar power systems are installed, they generally require little maintenance and can generate electricity for decades. This is in contrast to coal-based power systems, which require substantial capital investment to establish large power plants and the associated infrastructure.
The levelised cost of electricity (LCOE) from solar power has become competitive with, and often cheaper than, traditional fossil fuel sources like coal. In 2016, a major commercial solar installation bid an extremely low price for photovoltaic (PV) power, levelling the playing field between solar and fossil fuels. Today, solar PV projects can deliver energy at half the cost of coal, even without considering the costly negative impacts of coal, such as environmental degradation, carbon pollution, and health issues for local communities.
While solar power may have had higher upfront installation costs in the past, technological advancements and economies of scale have driven down the price of solar panels and improved their efficiency. This has made solar power more affordable for residential and commercial properties, challenging the argument that solar energy is too expensive.
Additionally, solar power is eligible for various rebates, feed-in tariffs, and tax credits, further reducing the financial burden on adopters. These financial incentives, combined with the decreasing costs of solar technology, make solar power an economically attractive option for individuals, businesses, and energy companies.
