  While renewable energy sources have minimal fuel costs, they incur operational and maintenance (O&M) expenses throughout their lifespan. These expenses include equipment maintenance, repairs, monitoring, and labor costs. For example, wind turbines require regular inspection and maintenance to ensure optimal performance and prevent component failures. Geothermal power plants may experience scaling or corrosion issues that necessitate periodic maintenance shutdowns. Effective O&M strategies and technological advancements that reduce maintenance frequency and costs are essential for improving the long-term economic viability of renewable energy projects.

• Levelized Cost of Energy (LCOE)

  The Levelized Cost of Energy (LCOE) is a metric used to compare the cost-effectiveness of different energy sources over their entire lifecycle. LCOE incorporates all relevant costs, including capital expenditures, operational expenses, fuel costs (if any), and decommissioning costs, and divides them by the total energy output. Renewable energy technologies have seen significant reductions in LCOE in recent years, making them increasingly competitive with fossil fuels. Solar and wind energy, in particular, have achieved LCOE levels comparable to or lower than those of conventional power plants in many regions. Continued reductions in LCOE are vital for accelerating the transition to a sustainable energy system.

• Externalities and Societal Benefits

  Economic feasibility assessments should also account for the externalities associated with different energy sources. Fossil fuels impose significant external costs on society, including air and water pollution, greenhouse gas emissions, and health impacts. Renewable energy resources offer substantial societal benefits, such as reduced pollution, improved public health, climate change mitigation, and energy security. Monetizing these externalities and incorporating them into economic evaluations can provide a more accurate assessment of the true economic value of renewable energy. For example, carbon pricing mechanisms, such as carbon taxes or cap-and-trade systems, can internalize the cost of carbon emissions from fossil fuels, making renewable energy sources more economically attractive.

In summary, the economic feasibility is a multifaceted consideration in the deployment of energy resources that are not depleted when used. Addressing high initial investment costs, reducing operational expenses, improving LCOE, and accounting for externalities are essential for ensuring the economic competitiveness and widespread adoption of these renewable energy sources. Continued technological innovation, supportive government policies, and a comprehensive assessment of societal benefits are crucial for unlocking the full economic potential and transitioning towards a sustainable energy future.
