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.
The global public overwhelmingly favours multilateral cooperation
A global opinion poll published today by the World Economic Forum finds that a clear majority of people in all regions of the world say they believe cooperation between nations is either extremely or very important. It also finds that a large majority rejects the notion that national improvement is a zero-sum game, and that most people feel that immigrants are mostly good for their adopted country.
The research, covering a sample size of over 10,000 people from every region of the world, was commissioned ahead of next week’s World Economic Forum Annual Meeting in Davos-Klosters, Switzerland. The findings can be viewed as an endorsement by the public of the key principles of the multilateral system. It also roundly debunks the negative notion of immigrants that has raced to the top of the news agenda across Europe, North America and elsewhere.
However, regional viewpoints differ. Asked how important it is that countries work together towards a common goal, a global average of 76% said they believe it is either extremely important or very important. These sentiments are felt most strongly in South Asia and sub-Saharan Africa, where 88% share the same view. At the other end of the scale, only 61% of Western Europeans and 70% of North Americans say they consider cooperation to be extremely or very important.
Asked whether their country has a responsibility to help other countries in the world, South Asians again registered the highest levels of concurrence, with 94% answering positively compared to a global average of 72%. Again, North Americans and Western Europeans were the least effusive, with only 61% and 63% respectively answering in the affirmative.
While a global majority of respondents – 57% – say they believe that immigrants are “mostly good” for their new country, only 40% of those living in Eastern Europe and Central Asia and 46% of respondents in Western Europe subscribe to the same opinion. Perhaps unsurprisingly given its history, North Americans trailed only South Asians in their approval of immigrants, with 66% saying they believe immigrants are mostly good.
The data, which came about as a result of a collaboration with Qualtrics, will be used in panel discussions and workshops at the Annual Meeting as a guide for participants as they explore how to build an architecture for global governance that is capable of fostering the international collaboration necessary to solve the world’s most critical challenges.
One finding that will surely prove valuable to the discussions is the fact that, while most people still believe in the power of international cooperation, they share a much less positive view of their own country when it comes to social progress. This despondency at the lack of upward mobility is felt most acutely in Western Europe, where only 20% of respondents said they feel it is either extremely common or somewhat common for someone to be born poor and become rich through hard work. Respondents in the United States, where the ideal of the American Dream is deeply rooted in the national consciousness, were only a little more positive with 34% saying they believe the statement to be either extremely or very common.
“The combination of climate change, income inequality, technology and geopolitics pose an existential threat to humanity. What we see with this research is that, while the international community’s capacity for concerted action appears constrained, the overwhelming desire of the global public is for leaders to find new ways to work together that will allow them to cooperate on these critical shared challenges we all face,” said Klaus Schwab, Founder and Executive Chairman of the World Economic Forum.
“This is a bold reminder that listening is critical to leadership,” said Bill McDermott, CEO of SAP. “If we just have the courage to ask, the people always know what problems need solving. I’m proud we will enter this annual meeting with such a compelling view of the human experience, unfiltered, from the people who are actually living it.”
As well as providing insight into the global public’s attitudes on opportunity and international relations, the survey also shines a light on other important matters of global importance in 2019. For example, on the subject of sustainability, 54% of respondents said they have either a “great deal” or “a lot” of trust in what climate scientists say. At the other end of the spectrum, the region in the world where most respondents have little or no trust in climate scientists is North America, with only 17% responding positively.
When it comes to the role of technology in society, the number of people that say they believe technology does more good than harm outnumber those who say they think it does more harm than good by a factor of nearly four to one. However, when asked whether they agree with the statement that technology companies are more interested in making the world a better place rather than simply making money, responses differed markedly between regions. The region of the world where respondents take the most positive view of technology is sub-Saharan Africa, where 66georg% of those surveyed agree that technology companies want to make the world a better place, followed by South Asia (64%) and East Asia and the Pacific (63%). This compares to only 39% of Western Europeans and 40% of North Americans and respondents from Eastern Europe and Central Asia.
Oil Market Report: A marathon, not a sprint
Last month, we asked if there was a floor under prices following the signing of a new Vienna Agreement that aims to re-balance the oil market. Following an initial burst of enthusiasm for the deal, scepticism set in, alongside worries about the global economic background. Prices fell by $10/bbl with Brent crude oil bottoming out on 24 December at just above $50/bbl. For the producers, this was unwelcome, but for consumers it provided a nice present for the holidays. In the US Gulf Coast, gasoline prices in early January averaged $1.89/gal versus the summer peak of $2.79/gal and in India, prices are about 14% below the early October peak. Recently, leading producers have restated their commitment to cut output and data show that words were transformed into actions. In December, OPEC production fell by almost 600 kb/d and Saudi Arabia has signalled that, for its part, further significant cutbacks will take place in January and beyond.
The Brent price has moved back above $60/bbl, so the answer to our question posed last month seems to be a qualified yes, at least for now. However, the journey to a balanced market will take time, and is more likely to be a marathon than a sprint. While Saudi Arabia is determined to protect its price aspirations by delivering substantial production cuts, there is less clarity with regard to its Russian partner. Data show that Russia increased crude oil production in December to a new record near 11.5 mb/d and it is unclear when it will cut and by how much. Other non-OPEC countries joining in the output deal saw higher output, including Mexico.
Elsewhere, there are signs that market re-balancing will be gradual. The trajectory of Iran’s production and exports remains important. In December, total exports increased slightly to over 1.3 mb/d. With US waivers allowing Iran’s major customers to buy higher volumes than was previously thought, more oil will remain in the market in the early part of 2019. Venezuela has seen the collapse of its oil industry slow during the second half of 2018 with production falling recently by about 10 kb/d each month rather than by the 40 kb/d we saw earlier in the year. The level of output in the world’s biggest liquids producer, the United States, will once again be a major factor in 2019. We saw incredible and unexpected growth in total liquids production of 2.1 mb/d in 2018. For this year, we have left unchanged for now our forecast for growth of 1.3 mb/d. While the other two giants voluntarily cut output, the US, already the biggest liquids supplier, will reinforce its leadership as the world’s number one crude producer. By the middle of the year, US crude output will probably be more than the capacity of either Saudi Arabia or Russia.
For oil demand, there is a mixed picture. Falling prices in 4Q18 helped consumers and there are signs that trade tensions might be easing. In many developing countries, lower international oil prices coincide with a weaker dollar as the likelihood of higher US interest rates fades for now. However, the mood music in the global economy is not very cheerful. Confidence is weakening in several major economies. In the short term, there is added uncertainty about oil demand due to the onset of the northern hemisphere winter season, with low temperatures seen in the past few days in many places. For now, we retain our view that demand growth in 2018 was 1.3 mb/d, and this year it will be slightly higher at 1.4 mb/d, mainly due to average prices being below year-ago levels.
In the meantime, refiners face a challenging year. Processing capacity will increase by 2.6 mb/d, the biggest growth for four decades, while margins are already pressured by low gasoline cracks due to oversupply and weak demand. The well-trailed changes to the International Maritime Organisation’s marine fuel regulations due in 2020 are another big issue for some refiners as they seek to find outlets for unwanted high sulphur fuel oil. By the end of the year, all industry players, upstream and downstream, may feel as if they have run a marathon.
Macroeconomic Stability in Lao PDR Amidst Uncertainty
Economic growth in Lao PDR is estimated at 6.5 percent in 2018, down from 6.9 percent in 2017, in part due to the adverse impact of the recent widespread floods. The construction of infrastructure, export of electricity, and service sector have been the main drivers of growth in 2018. The medium-term economic outlook is favorable but subject to risks, including a volatile global economic environment, according to the latest edition of the World Bank’s Lao Economic Monitor, released today.
“Economic growth remains robust in Lao PDR, and the government has made important inroads on the reform front, notably on revenue collection. The path of fiscal consolidation, despite the recent natural disasters, is welcome,” said Nicola Pontara, World Bank Country Manager for Lao PDR. “Looking forward, Lao PDR should continue to invest in its human capital to boost productivity, which is key to support both long-term growth and further poverty reduction.”
According to the report, the fiscal deficit is estimated to narrow from 5.3 percent of GDP in 2017 to 4.7 percent of GDP in 2018. The government is committed to reducing public debt, estimated at around 60 percent of GDP, by following a path of fiscal consolidation, with emphasis on raising revenue collection, tighter control of public spending, and better management of public debt. Inflation is estimated at around 2.1 percent in 2018 from an average of 0.8 percent in 2017 driven by both higher average domestic food and fuel prices and a depreciation of Lao Kip against major currencies.
The report includes a thematic section on human capital, which highlights the importance of investing in people. A child born today in Lao PDR is only 45 percent as productive as she could be if she enjoyed full education and healthcare. Stunting levels among Lao children are higher, and the probability of survival to age five is lower, than those of countries at similar income levels. Moreover, despite an average of actual 10.8 years accumulated in school by age 18, once adjusted for the quality of learning, children in Lao PDR only complete 6.4 years of schooling.
The report concludes that improving human development outcomes in health and education in Lao PDR requires a combination of systemic and sector-specific interventions. For instance, better and greater investments in mother and child health, as well as improved quality of education since early childhood are important interventions to increase the productivity and well-being of new generations. Combined with institutional reforms to improve service delivery mechanisms in health and education, these policies can support the country’s long-term economic prospects.
