Floating solar technologies are creating major new opportunities to scale up solar energy around the world, particularly in countries with high population density and competing uses for available land.
The use of floating solar – deployment of photovoltaic panels on the surface of bodies of water – has grown more than a hundred-fold in less than four years, from a worldwide installed capacity of 10 megawatts at the end of 2014 to 1.1 gigawatts by September 2018, according to the first market report on floating solar, produced by the World Bank Group and the Solar Energy Research Institute of Singapore (SERIS).
The report estimates the global potential of floating solar, even under conservative assumptions, to be 400 gigawatts – roughly the total capacity of all solar photovoltaic installations worldwide at the end of 2017.
“Floating solar technology has huge advantages for countries where land is at a premium or where electricity grids are weak,” said Riccardo Puliti, Senior Director for Energy and Extractives at the World Bank. “Governments and investors are waking up to these advantages, and we are starting to see interest from a wide range of countries in Africa, Asia and Latin America.”
At some large hydropower plants, covering just 3-4 percent of the reservoir with floating solar could double the capacity of the plant, potentially allowing water resources to be more strategically managed by utilizing the solar output during the day. Combining solar and hydropower can also be used to smooth the variability of solar output.
In a number of countries, floating solar also allows power generation to be placed more closely to urban areas or other demand centers. And while up-front costs are slightly higher, the costs over time of floating solar are at par with traditional solar, because of floating solar’s higher energy yield – due to the cooling effect of water.
In water reservoirs, floating solar panels can reduce evaporation, improve water quality, and serve as an energy source for pumping and irrigation.
Asia is the epicenter for this new technology’s expansion, with large floating solar plants at either the tens or hundreds of megawatt scale being installed or planned in China, India and Southeast Asia.
“We fully expect demand to grow for this technology and for floating solar to become a larger part of countries’ plans for expanding renewable energy,” said Puliti. “It will be important to ensure that best practices are shared among countries and development minimizes any environmental impacts.”
The market report is the first in a series of reports on floating solar – titled “Where Sun Meets Water” – being produced by the World Bank Group and SERIS, with funding provided by the World Bank’s Energy Sector Management Assistance Program (ESMAP) and the Government of Denmark.
New systemic approach needed to tackle global challenges
The impacts of the coronavirus on people’s health and daily life, stock markets, and businesses illustrate the increasingly interconnected nature of the challenges facing governments around the world. Putting systemic thinking at the centre of policy making will be essential to address these issues in an era of rapid and disruptive change, according to a new joint report by the OECD and the International Institute for Applied Systems Analysis (IIASA).
Systemic thinking for policymaking: The potential of systems analysis for addressing global policy challenges in the 21st century aims to highlight to policymakers how systems research can be used to understand the complex issues facing society, anticipate the consequences of our decisions, and build resilience. The authors argue that, to tackle planetary emergencies linked to the environment, the economy, and sociopolitical systems, policymakers need to understand their systemic properties, including tipping points, interconnectedness, and resilience.
“The systems approach can promote cross-sectoral, multidisciplinary collaboration in the process of policy formulation by taking proper account of the crucial linkages between issues generally treated separately within different specialisations and scientific and institutional “silos””, said Gabriela Ramos, Chief of Staff. “The approach provides a methodology to achieve a better understanding of the non-linear behaviour of complex systems and improve the assessment of the consequences of policy interventions. The ultimate objective is to improve the capacity of policies to deliver better outcomes for people.”
“Unless we adopt a systems approach, unless we employ systems thinking, we will fail to understand the world we are living in. This is a world made up of complex systems, systems of systems interacting with each other, and changing each other by that interaction and the links between them. If we are to tackle these issues, governments must change the ways in which they make and implement policies. An acceptance of complexity shifts governments from a top-down siloed culture to an enabling culture where evidence, experimentation, and modeling help to inform and develop stakeholder engagement and buy-in,” concludes IIASA Director General Albert van Jaarsveld.
“The report shows the considerable potential of mainstreaming systemic thinking into policymaking, including within the OECD itself. As part of an agreed work program between the two organizations, the aim is to establish specific bilateral projects in the different areas of policymaking,” explains Acting Chief Operations Officer of IIASA, Jan Marco Müller.
The report highlights the application of systems thinking beyond the fields of analysis, modeling, and the formulation of policy, and that systems thinking has immediate application in developing human capital through education, training, and team building. Perspectives are drawn from a range of disciplines and methodologies including economics, social science, and policymaking, but also from the physical and biological sciences and engineering. The authors show how cross-sectoral, multidisciplinary collaboration can take account of the crucial linkages between issues generally treated within different specializations, and scientific and institutional silos.
Closer trade cooperation in combination with robust land use strategies could, for instance, increase the resilience of global food markets to the impacts of climate change, while an integrated approach to the management of water, energy, and land would provide experts and policymakers with a better understanding of the benefits and challenges of sustainably meeting future demand for resources. Another example cited in the report is the link between education and demographic change, where the authors highlight how lifelong education strategies, starting from early childhood, can promote productive working lives and healthy ageing.
Uganda Can Create Higher Labor Productivity Jobs by Improving Trade and Business Environment
Uganda’s economy needs to gradually create more jobs for its fast-growing and youth population. To accelerate economic growth and drive transformation, these jobs will need to bring higher labor productivity, says a new World Bank report launched today.
The report, “Uganda: Jobs Strategy for Inclusive Growth,” identifies ten challenges to achieving this, including slowing trends in economic growth. Labor force growth is quickening, urbanization is sluggish, as is the transition from non-wage to wage employment, notes the report.
With a median age of just 15.9, Uganda is the world’s second youngest country, whereas around 700,000 young people reach working age every year. This number will rise to an average of a million in the decade from 2030-2040, potentially exacerbating the mismatch between labor demand and supply. While Uganda’s youth are renowned for being highly enterprising, there is not enough demand for all of them to be producing for the domestic market. Fewer than 4 percent of the self-employed are employers (job creators), 52 percent are working for themselves, and 43 percent work as unpaid family workers.
Nearly two thirds of Ugandans remain employed in agriculture, and almost three quarters of young Ugandans enter the workforce on their family farm, according to data from the 2016/17 Uganda National Household Survey. Global experience published in a report by the World Bank Jobs Group titled, “Pathways to Better Jobs in IDA Countries,” suggests waged employment allows economies to grow faster; reduces poverty faster; and brings more reliable earnings and hours. Moreover, as people switch from agriculture they move to urban areas and shift from being self-employed to working for a wage.
The strategy recommends improving trade by investing in initiatives that enable businesses to compete favourably, grow and thrive; attract more foreign direct investment; implement policies that facilitate regional trade; promote urban development through investing in secondary cities; and incentivize commercial agriculture by encouraging collaboration across income-elastic value chains. The strategy also calls on government to realign youth employment programs to prepare graduates for semi-skilled work.
Agribusiness is particularly promising. Demand for food is rising, and as urbanization continues, and incomes rise, the demand for higher value produce; like meats, dairy produce, fresh vegetables, fresh fruits and juices will expand fast.
“Agribusiness and agro-processing can create many productive jobs in the food system, from transport, storage, and warehousing, to retail and restaurants. Blessed with good weather and soil, Uganda can be a food basket for Africa while closing the employment gap,” said Tony Thompson, World Bank Country Manager for Uganda.
First Road Safety Profile Report to Help Save Lives on the Road
The World Bank’s Global Road Safety Facility (GRSF) presented the Guide for Road Safety Opportunities and Challenges: Low- and Middle-income Country Profiles during the 3rd Global High-Level Conference on Road Safety in Stockholm. The guide gives a precise assessment on the magnitude and complexity of road safety challenges faced by low-and middle-income countries (LMICs) and helps policy makers understand the road safety framework in context of their own country systems and performance. The guide also helps countries to build and appreciate the business case for vital road safety investment.
LMICs are facing a major challenge in road safety. Each year, 1.35 million people are killed on the worlds’ roads, and a further 50 million are injured, with the vast majority of these (over 90 percent) occurring in LMICs.
One major barrier to improving this situation is a lack of understanding of the problem due to deficient information. Many vital metrics of road safety performance are not measured effectively in most LMICs, including the actual number of road crash fatalities and serious injuries. Measures of progress such as safety rating of roads, age and safety of vehicles, and safety behaviors such as helmet or seatbelt use are also commonly not known. This limits every aspect of road safety management and delivery, including resource allocation, advocacy, intervention selection, and prioritization of resources.
Information is required to guide progress across all pillars of road safety—management, roads, speed, vehicles, road users, and post-crash care— in order to understand deficiencies and opportunities, set ambitious targets for improvement, monitor progress and develop advocacy and commitment for interventions that work.
The Road Safety Country Profiles present information on all these pillars along with information on the current status for each country and region along with extensive information on key risk factors, issues and opportunities. This report provides a baseline for monitoring progress on vital metrics for road safety. It will be updated to measure progress on evidence-based road safety measures during the current decade.
The report also guides action: Clear advice and references regarding robust policies and other interventions are provided to countries facing specific challenges, allowing them to take direct action on priority issues and opportunities.
“The road safety agenda is critical for development, from building and maintaining human capital, to ensuring long-term growth and poverty reduction prospects. This groundbreaking report responds to the urgent need to collect and document road safety performance data—an important step toward a clear understanding of the problem,” said Makhtar Diop, Vice President for Infrastructure, World Bank. “As the road safety challenge moves into a new decade, this report will help build on achievements at the local, regional and national levels, and strengthen the foundation for a new phase of action.”
The guide was developed by GRSF together with the World Bank, with funding support from UK Aid and the World Bank. GRSF has been a leading global actor for the global road safety agenda and plays a vital role in providing guidance, leadership, and funding to LMICs, international partner organizations, academia, and NGOs via a wide range of research studies, guidance documents and technical support.
The GRSF gratefully acknowledges the many sources employed to calculate various measure. In particular, we thank to the World Health Organization (WHO); the Institute for Health Metrics and Evaluation (IHME); the International Road Assessment Programme (iRAP); and the United Nations Environment Programme (UNEP) for the significant use we have made of their data.
