Increasing Demand

Renewable energy is one of the critical solutions to address the ever-increasing demand for energy. In developing countries such as Zimbabwe where the conventional generation hardly sustains half of the nation’s energy demands, renewable energy solutions are compensating for the deficit. Among these renewables, solar energy technologies have witnessed rapid growth. In most cases, solar energy installers assume to have all the knowledge required in the field. However, many technical barriers still exist within the field of solar energy systems. For solar energy systems which are synchronized to the grid, the integration of these renewables pose a serious stability and protection threat to the already unstable and even stable grids. In this paper, some of the technical problems being faced are discussed. Policy issues as well as the possible solutions needed in order to realize full, unhindered growth of solar energy are addressed.

Electrical Loads

The millions of users in developing countries often live far off the electric grid (rural areas) which seems not very cost effective extending the national grid to these rural areas as per respective governments. Africa’s total primary energy supply has seen an increasing annual rate of about 3%, seeming to be the highest among all other continents. The African continent as a whole is endowed with large renewable energy potential, varying in type across diverse geographic locations. These resources, and the settings in which they exist, can point to country or regional specific renewable energy solutions to fit each nation’s strengths and needs. In Sub-Saharan Africa, reliable access to electric power must be consider a basic precondition to improve people’s lives as it further promote education, health care and economic growth via the creation of sustainable and clean energy jobs. Until recently, renewable energy technologies (RETs) have been confronted with a huge up-front cost and technologies in development but massive and global deployment of renewable energy systems has led to significant cost reductions and performance improvements and the hope is to see increasing uptake of RETs by African countries. Cameroon a Central African country is heavily reliant on hydropower, which contributes an estimated 60% to the country’s total installed 1,400MW capacity in 2015. In addition, there is constants power failure due to the non-reliability of the electric grid and load shedding to meet increasing demand. However, climate change poses additional huge risk (large reservoirs and dams drying up) and to meet the increasing demand, Cameroon is being forced to seek alternative power sources. This paper proposes the need for a sustainable hybrid energy system design and the development of an effective design, simulation and analysis approach of stand-alone off-grid in Cameroon as a potential optimal solution to help power community electrical loads. Finding an optimized mix of renewable energy technologies for Bandjoun and Muyuka were the goals of this paper.

Policy And Planning

Since 2007, large and unexpected declines in generation costs for renewable energy systems, particularly solar but also wind, combined with policy measures designed to limit greenhouse gas emissions, have created a paradigm shift in energy systems. Variable renewable energy now dominates total investment in electricity power generation systems. This dominance of variable renewable energy in investment has thrust the systems integration task of matching electricity supply with demand to center stage, presenting new challenges for energy policy and planning as well as for the institutional organization of power systems. Despite these challenges, there is ample reason to believe that variable renewables will attain very high levels of penetration into energy systems, particularly in regions well endowed with solar and wind potential. Similar to their success with mobile phone telephony, many developing countries have a significant opportunity to leapfrog directly to more advanced energy technologies that are low cost, reliable, environmentally more benign, and well suited to serving dispersed rural populations.

Proposed Model

The purpose of this study is to identify the most relevant renewable energy technologies for buildings and to assess the effectiveness of their implementation in the long term for Kuwait. Methods of analogies and comparisons were used to determine the features of energy efficiency based on the technologies under study. The study proposes the methodological approach to assessing the effectiveness of the introduction of renewable energy technologies, determining the direction of increasing the energy efficiency of buildings and the investment efficiency of introducing these technologies. Renewable energy efficiency analysis for buildings in Kuwait confirms that solar energy systems have been the most widely available for widespread use of solar energy over the past three years. An increasing level of energy efficiency with a decrease in the notional cost of increasing energy savings is characteristic of solar collectors with booster reflectors. The proposed model for assessing the level of energy saving provides an opportunity for economic justification of introducing renewable energy technology in buildings.

Energy Production System

: A sustainable energy production system fulfills its goal while being environmentally, socially, and technically sound. The intermittent availability and viability of renewable energy makes this vision a gradual and long-suffering process. In the rapid result-oriented economy, concerns regarding the environment are treated with desperate solutions that may add fuel to the fire. Although substantial research has been going on in the development of emerging technologies and refinement of established systems, we need to be reminded of the larger goal in mind: a benign and sustainable environment. Closing a door on a problem and not opening several new ones is what we must yearn to achieve. Renewable energy systems and their utility may unintentionally harm a different subset of the ecosystem. Solar energy systems are a more recent candidate with a high annual growth rate and thus, are still in the nascent stage to realise the bruised potential of the technology. By 2050, 60 million tons of solar waste will be produced if it is not resolved efficiently. To achieve environmental sustainability, it is imperative to work towards recycling redundant systems, establishing producer responsibility, fulfilling social needs and optimising future technology. By integrating aspects of the research on solar energy systems, their environmental risks, and their potential to create a sustainable ecosystem, this review article attempts to cater to environmental decision making and direct the eventual research and analysis towards their original unified objective.

Means Of Production

The adoption of renewable energies contributes to sustainable development worldwide. Entrepreneurs are key agents in facilitating their promotion, as they improve the mix of the means of production and thus transform renewable energy technologies into viable energy systems. Nonetheless, the literature tends to treat entrepreneurs as a homogeneous group, thus preventing comprehensive understanding of their motivations, behaviors, capabilities, and effects. This study addresses this research gap by identifying and categorizing the various characteristics of these entrepreneurs and developing an integrated classification method. Four examples of renewable energy entrepreneurs, in China, Denmark, Germany, and India, are analyzed according to the proposed classification method, while demonstrating their differences. Thus, through proposing a new analytical typology, this study improves our understanding of renewable energy entrepreneurs and their significant role in the promotion of renewable energy worldwide.
