1.0 Introduction
1.1 Background of Study
The history of government incentives and policies promoting renewable energy investment dates back to the late 20th century, driven by the growing awareness of environmental issues and the need for sustainable energy solutions. The oil crises of the 1970s were pivotal, highlighting the vulnerabilities associated with dependence on fossil fuels and prompting governments to seek alternative energy sources. in the 1980s and 1990s, early adopters such as Denmark and Germany began to implement significant policies to support renewable energy. Denmark's focus on wind energy and Germany's Energiewende (energy transition) strategy laid the foundation for large-scale renewable energy adoption. Germany's Renewable Energy Sources Act (EEG) of 2000 introduced feed-in tariffs, guaranteeing fixed payments for renewable energy producers and significantly boosting investments in wind and solar energy.
The early 2000s saw a proliferation of renewable energy policies globally. The United States, under the Energy Policy Act of 2005, introduced production tax credits and investment tax credits to support renewable energy projects. China, recognizing the dual benefits of energy security and pollution reduction, launched its Renewable Energy Law in 2005, leading to rapid growth in wind and solar installations.
In recent years, the Paris Agreement of 2015 has further galvanized international efforts to promote renewable energy. Countries have set ambitious targets for renewable energy deployment, supported by various incentives such as subsidies, grants, and research funding. The European Union's Green Deal and the United States' Inflation Reduction Act of 2022 exemplify current large-scale policy frameworks aimed at accelerating the transition to renewable energy.
The global push towards sustainability has placed renewable energy at the forefront of modern energy strategies. Governments worldwide recognize the critical role of renewable energy in reducing greenhouse gas emissions, enhancing energy security, and fostering economic development. Consequently, a variety of incentives and policies have been implemented to promote investment in renewable energy sources such as solar, wind, hydro, and bio-energy. These incentives include tax credits, subsidies, feed-in tariffs, renewable portfolio standards, and research and development support. Understanding the impact of these government measures is crucial for evaluating their effectiveness and for designing future policies that can further accelerate the transition to a sustainable energy future.
The transition from fossil fuels to renewable energy sources is essential to address climate change and achieve sustainable development. Renewable energy technologies, such as solar, wind, hydro, and bio-energy, offer significant environmental benefits by reducing greenhouse gas emissions and decreasing dependence on finite fossil fuels. However, the initial investment costs for renewable energy projects are often high, creating financial barriers for widespread adoption. Governments worldwide have recognized the need to support renewable energy development through various incentives and policy measures. These interventions aim to create a favorable investment climate, reduce financial risks, and ensure a stable return on investment for renewable energy projects. Common government incentives include tax credits, subsidies, feed-in tariffs, renewable portfolio standards, and grants for research and development. Therefore, in Nigeria where the research was carried out, the activities that was conducted is to know the impact of government incentives and policies in promoting renewable energy investment.
1.2 Statement of Problems
Investigation revealed that the effectiveness of government incentives and policies often varies due to inconsistencies and frequent changes in policy frameworks. Such instability can create uncertainty for investors, undermining confidence in long-term returns and deterring investment in renewable energy projects. While financial incentives such as tax credits, subsidies, and feed-in tariffs have been instrumental in promoting renewable energy, they are often insufficient to cover the high initial capital costs associated with these projects.
Additionally, the integration of renewable energy into existing power grids poses significant technical and logistical challenges. Renewable energy sources, such as solar and wind, are intermittent and require advanced grid management and storage solutions. Inadequate infrastructure and technological support can lead to inefficiencies and increased costs, affecting the overall feasibility of renewable energy investments.
Furthermore, complex and cumbersome regulatory procedures can delay project approvals and increase costs. Streamlining regulatory processes and ensuring clear, transparent, and supportive regulatory environments are essential for attracting investment and accelerating renewable energy deployment. In many regions, small and medium-sized enterprises and local communities face difficulties accessing government incentives compared to larger corporations. This disparity can hinder the equitable distribution of renewable energy benefits and limit community-led renewable energy initiatives. Hence, it is against this backdrop that this study aims to examine the impact of government incentives and policies in promoting renewable energy investment.

1.9 Definition of Terms
Renewable Energy:
It refers to energy derived from natural sources that are replenished constantly. Common examples include solar, wind, hydro, geothermal, and biomass energy. These sources of energy are considered environmentally friendly as they produce little to no greenhouse gas emissions compared to fossil fuels (IRENA, 2020).
Government Incentives:
They are financial or policy measures implemented by governments to encourage the development and adoption of renewable energy. These can include tax credits, subsidies, grants, feed-in tariffs, and renewable portfolio standards (Bird, L., Bolinger, M., et al., 2005).
Feed-in Tariffs (FiTs):
Feed-in tariffs are policies designed to accelerate investment in renewable energy technologies by offering long-term contracts to renewable energy producers, typically based on the cost of generation of each technology. They guarantee a fixed price for the energy produced, providing stability and financial security to investors (Couture, T., & Gagnon, Y. 2010).
Subsidies:
They are financial contributions provided by the government to support renewable energy projects. These can come in the form of direct cash grants, low-interest loans, or other financial benefits that reduce the overall cost of renewable energy investments (Sawin, 2004).
Tax Credits:
Tax credits are deductions from a taxpayer's liability that are offered by the government to encourage investment in renewable energy. Examples include the Investment Tax Credit (ITC) and the Production Tax Credit (PTC) in the United States, which reduce the cost burden on renewable energy developers (Carley, 2009).
Renewable Portfolio Standards (RPS):
Renewable Portfolio Standards are regulatory mandates to increase the production of energy from renewable sources. RPS requires utilities to ensure that a specified percentage of the electricity they sell comes from renewable resources (Yin, H., & Powers, N. 2010).
Grid Integration:
Grid integration refers to the process of incorporating renewable energy sources into the existing power grid. This involves managing the variable output from renewable sources and ensuring reliability and stability in the power supply (Lund et al., 2006).
Investment Risk:
Investment risk in the context of renewable energy refers to the uncertainties and potential financial losses associated with investing in renewable energy projects. These risks can arise from regulatory changes, market fluctuations, and technological challenges (Wüstenhagen, R., & Menichetti, E. 2012).
