Abstract The research investigated tenant understanding and preparedness to embrace renewable energy practice as an alternative to public power supply during an outage from the national grid. International standards of sustainable building occupation from Building Research Establishment Environmental Assessment Methods (BREEAM) and Leadership in Energy and Environmental Design (LEED) were adopted to form the parameters of the investigation. The study covered knowledge and utilization of the solar energy system amongst tenants and their readiness to embrace alternative energy systems as well as incentives from the management Company of Turaki Ali House to encourage sustainable occupation. A qualitative and quantitative technique was employed; the interview conducted covered two members of the tenants’ committee and a member of the staff from the management company who has been the desk officer responsible for the property for twenty years. Fifty-six questionnaires were distributed among tenants with forty-one questionnaires returned and used for the analysis. Results from the research revealed limited knowledge of the advantages of the solar energy system over generators; in addition, there was apprehension to embracing the solar system due to the higher initial costs of acquisition and substandard solar systems and components. Managers of the property are reported not have been performing their contractual obligation of the lease, thus justifying the use of individual generators by tenants despite the inherent dangers associated with the practice. The research concluded with a recommendation to raise awareness and encourage the use of sustainable energy sources by means of reviewing the content of tenancy agreements to ensure compliance with sustainable building occupation standards.

Leading Position

The article aims to study current trends in the use of solar energy in Ukraine and the world as one of the main directions of decarbonization of the national economy. The authors systematize the prospects, advantages and disadvantages of the development of renewable energy sources. They conducted a comparative analysis of the "efficiency" of solar energy in some countries and Ukraine. The authors determined that the leading position in terms of the share of energy consumed from renewable sources is occupied by countries with developed economies due to the availability of effective motivational mechanisms. From the experience of EU countries, the authors concluded that renewable energy sources form a prerequisite for obtaining additional socio-economic and environmental effects. In the presence of favorable market conditions, renewable energy sources can increase the level of energy security in the country and its energy independence. The article analyzes the legislation of Ukraine on stimulating the development of alternative energy. The authors proposed two opposed ways of further developing solar energy in Ukraine. In particular, the country can implement methods of using alternative energy, which developed countries have successfully implemented. Another area involves increasing research and innovation in implementing, using, maintaining, and utilizing energy-generating devices from alternative energy sources. Despite the polarity of the proposed directions for further development of renewable energy, in both cases, the state policy on attracting investment and promoting the use of energy from alternative energy sources is crucial. In addition, the authors noted the benefits for society from the development and implementation of alternative energy sources. The scaling up and promotion of energy production technologies from alternative sources can reduce carbon emissions, which has been an urgent problem globally.

The Impact

The transition towards a renewable energy system is essential in order to reduce greenhouse gas emissions. The increase in the share of variable renewable energy sources (VRES), which mainly comprise wind and solar energy, necessitates storage technologies by which the intermittency of VRES can be compensated for. Although hydrogen has been envisioned to play a significant role as a promising alternative energy carrier in a future European VRES-based energy concept, the optimal design of this system remains uncertain. In this analysis, a hydrogen infrastructure is posited that would meet the electricity and hydrogen demand for a 100% renewable energy-based European energy system in the context of 2050. The overall system design is optimized by minimizing the total annual cost. Onshore and offshore wind energy, open-field photovoltaics (PV), rooftop PV and hydro energy, as well as biomass, are the technologies employed for electricity generation. The electricity generated is then either transmitted through the electrical grid or converted into hydrogen by means of electrolyzers and then distributed through hydrogen pipelines. Battery, hydrogen vessels and salt caverns are considered as potential storage technologies. In the case of a lull, stored hydrogen can be re-electrified to generate electricity to meet demand during that time period. For each location, eligible technologies are introduced, as well as their maximum capacity and hourly demand profiles, in order to build the optimization model. In addition, a generation time series for VRES has been exogenously derived for the model. The generation profiles of wind energy have been investigated in detail by considering future turbine designs with high spatial resolution. In terms of salt cavern storage, the technical potential for hydrogen storage is defined in the system as the maximum allowable capacity per region. Whether or not a technology is installed in a region, the hourly operation of these technologies, as well as the cost of each technology, are obtained within the optimization results. It is revealed that a 100 percent renewable energy system is feasible and would meet both electricity demand and hydrogen demand in Europe.

California is one of the most climate-challenged regions of North America and is considered the vanguard of climate action in the United States. California's climate policy framework has strongly promoted the expansion of renewable energy infrastructure, and the state generates more solar energy than any other in the nation. Using the case of Lancaster, a city of 170,000 residents in northern Los Angeles County seeking to position itself as the “alternative energy capital of the world,” this article examines private investments in solar energy infrastructure as a response to California's entwined economic and ecological crises. Drawing on recent scholarship on socioecological fix, we argue that private accumulation through renewable energy infrastructures in California has required both the presence of crisis conditions and innovations in financial risk mitigation that manage tensions between mobility and fixity inherent in the formation of fixed capital. However, a narrow focus on short-term financial risk obviates other forms of risk, including future impacts of extreme weather on grid infrastructure and electricity supply. While this does not foreclose opportunities for solar energy infrastructure to support positive social and ecological transformation, we argue that such opportunities may be constrained under a mode of energy transition predicated on private accumulation.

Fact Finding

The DESERTEC project, a European Union (EU) initiative to harness solar energy by means of Concentrated Solar Power (CSP) from Africa for use in Europe, shows the enormous potential that exists in alternative energy sources for the sub-region once there is political will. The Trans-Mediterranean Renewable Energy Corporation (TREC), a network of scientists and politicians who have taken it upon themselves to solve Europe’s energy problem using sun from Africa, conducted three studies which evaluated the potential of renewable energy resources in the Middle East and North Africa (MENA), the expected needs for water and power in EU-MENA between now and 2050 and issues relating to the construction of an electricity transmission grid connecting the EU and MENA (EU-MENA-Connection), with a formula to turn the North African desert sun into electricity and transport same to Europe. This paper harnesses the TREC fact-finding studies in order to estimate how much the same ideas can be applied in many other parts of the world, Nigeria in particular. Investigation reveals that this association exists with huge potentials for an energy-starved country like Nigeria in harnessing her abundant hot sun in the north, which could go a long way in meeting the energy needs in that part of the country and beyond. Other benefits include unlimited supplies of clean electricity, agricultural gains, and creation of new industries, new jobs and new sources of income.

Game Changer

Sun provides abundant source of renewable energy that can be integrated with the electrical grid. Climate change issues have compelled policy makers to look into various ways to reduce carbon footprint and use green, renewable energy. Solar power, along with other alternative sources for energy, is quite popular these days. Talking about Solar, the primary disadvantage of solar power is that it obviously cannot be created during the night and power generated is also reduced during times of cloud cover. Energy Storage is a flexible asset that provides unprecedented flexibility in grid optimization. Cost effective solar energy storage methods are urgently needed due to the increased demand for solar power and due to its variability. But in today’s scenario, energy storage systems are not commercially economic for all customers, and that to more work needs to be done by industry, government, and regulators to support the continuing cost reductions. It is expected that the Energy Storage costs would slide to 41% by 2020.The value that solar and storage can together add to the energy system is leading to a more efficient, cleaner, and more secure future. However, solar energy storage becomes critical when unsteady sources of energy provide. Thus, affordable energy storage system along with the cheaper Solar energy would be lethal combination making an ultimate Game Changer for the Power Industry and Sustainability.
