Global solar PV market set for spectacular growth over next 5 years

MD Staff

The installation of solar PV systems on homes, commercial buildings and industrial facilities is set to take off over the next five years, transforming the way electricity is generated and consumed, according to the International Energy Agency’s latest renewable energy market forecast.

These applications – known collectively as distributed PV – are the focus of the IEA’s Renewables 2019 market report, which was released today.

The report forecasts that the world’s total renewable-based power capacity will grow by 50% between 2019 and 2024. This increase of 1,200 gigawatts – equivalent to the current total power capacity of the United States – is driven by cost reductions and concerted government policy efforts. Solar PV accounts for 60% of the rise. The share of renewables in global power generation is set to rise from 26% today to 30% in 2024.

The expected growth comes after renewable capacity additions stalled last year for the first time in almost two decades. The renewed expansion remains well below what is needed to meet global sustainable energy targets, however.

“Renewables are already the world’s second largest source of electricity, but their deployment still needs to accelerate if we are to achieve long-term climate, air quality and energy access goals,” said Dr Fatih Birol, the IEA’s Executive Director.

The report highlights the three main challenges that need to be overcome to speed up the deployment of renewables: policy and regulatory uncertainty, high investment risks and system integration of wind and solar PV.

Distributed PV accounts for almost half of the growth in the overall solar PV market through 2024. Contrary to conventional wisdom, commercial and industrial applications rather than residential uses dominate distributed PV growth, accounting for three-quarters of new installations over the next five years. This is because economies of scale combined with better alignment of PV supply and electricity demand enable more self-consumption and bigger savings on electricity bills in the commercial and industrial sectors.

Still, the number of solar rooftop systems on homes is set to more than double to some 100 million by 2024, with the top markets on a per capita basis that year forecast to be Australia, Belgium, California, the Netherlands and Austria.

“As costs continue to fall, we have a growing incentive to ramp up the deployment of solar PV,” said Dr Birol. The cost of generating electricity from distributed solar PV systems is already below retail electricity prices in most countries. The IEA forecasts that these costs will decline by a further 15% to 35% by 2024, making the technology more attractive and spurring adoption worldwide.

The report warns, however, that important policy and tariff reforms are needed to ensure distributed PV’s growth is sustainable. Unmanaged growth could disrupt electricity markets by raising system costs, challenging the grid integration of renewables and reducing the revenues of network operators. By reforming retail tariffs and adapting policies, utilities and governments can attract investment in distributed PV while also securing enough revenues to pay for fixed network assets and ensuring that the cost burden is allocated fairly among all consumers.

“Distributed PV’s potential is breathtaking, but its development needs to be well managed to balance the different interests of PV system owners, other consumers and energy and distribution companies,” Dr Birol said. “The IEA is ready to advise governments on what is needed to take full advantage of this rapidly emerging technology without jeopardising electricity security.”

According to the report’s Accelerated Case, improving economics, policy support and more effective regulation could push distributed PV’s global installed capacity above 600 GW by 2024, almost double Japan’s total power capacity today. Yet this accelerated growth is still only 6% of distributed PV’s technical potential based on total available rooftop area.

As in previous years, Renewables 2019 also offers forecasts for all sources of renewable energy. Renewable heat is set to expand by one-fifth between 2019 and 2024, driven by China, the European Union, India and the United States. The heat and power sectors become increasingly interconnected as renewable electricity used for heat rises by more than 40%. But overall, renewable heat potential remains vastly underexploited. The share of renewables in total heat demand is forecast to remain below 12% in 2024, calling for more ambitious targets and stronger policy support.

Biofuels currently represent some 90% of renewable energy in transport and their use is set to increase by 25% over the next five years. Growth is dominated by Asia, particularly China, and is driven by energy security and air pollution concerns.  Despite the rapid expansion of electric vehicles, renewable electricity only accounts for one-tenth of renewable energy consumption in transport in 2024. And the share of renewables in total transport fuel demand still remains below 5%. The Accelerated Case sees renewables in transport growing by an additional 20% through 2024 on the assumption of higher quota levels and enhanced policy support that opens new markets in aviation and marine transport.

Health spending set to outpace GDP growth to 2030

Newsroom

Published

on

Health expenditure will outpace GDP growth over the next 15 years in almost every OECD country, according to new OECD forecasts. Health spending per capita will grow at an average annual rate of 2.7% across the OECD and will reach 10.2% of GDP by 2030, up from 8.8% in 2018, according to a new OECD report.

‌Health at a Glance 2019: OECD Indicators says that the United States spent the most on health care in 2018, equivalent to 16.9% of GDP, above Switzerland, the next highest spending country, at 12.2%. Germany, France, Sweden and Japan all spent close to 11% of GDP, while a few countries spent less than 6% of their GDP on health care, including Mexico, Latvia, Luxembourg, and Turkey at 4.2%.

Health at a Glance outlines areas where spending could be more effective:

Increased use of generic drugs could save costs, but at the moment are only half  the volume of pharmaceuticals sold across OECD countries. Generics accounted for more than three-quarters of the volume of pharmaceuticals sold in Chile, Germany, New Zealand and the United Kingdom, but less than one-quarter in Luxembourg and Switzerland in 2017.

Health and social systems employ more workers now than ever before, with about one in every ten of all jobs in OECD countries found in health or social care. Shifting tasks from doctors to nurses and other health professionals can alleviate cost pressures and improve efficiency.

Increasing patient safety not only improves health, it can also save money. Almost 5% of hospitalised patients had a health care associated infection in 2015-17.

Health at a Glance 2019 highlights some worrying patterns in health outcomes and unhealthy lifestyles.

A  person born today can expect to live almost 81 years on average in OECD countries. But life expectancy gains have slowed recently in most OECD countries, especially in the United States, France and the Netherlands. 2015 was a particularly bad year, with life expectancy falling in 19 countries.

The causes include rising levels of obesity and diabetes that have made it difficult to maintain previous progress in cutting deaths from heart disease and stroke. Respiratory diseases such as influenza and pneumonia have also claimed more lives in recent years, notably amongst older people.

Opioid-related deaths have increased by about 20% across OECD countries since 2011, and have claimed about 400,000 lives in the United States alone. Opioid-related deaths are also relatively high in Canada, Estonia and Sweden.

Smoking, drinking and obesity continue to cause people to die prematurely and worsen quality of life:

Smoking rates are declining, but 18% of adults still smoke daily.

Alcohol consumption averaged 9 litres of pure alcohol per person per year across OECD countries, equivalent to almost 100 bottles of wine. Nearly 4% of adults were alcohol dependent.

Obesity rates continue to rise in most OECD countries, with 56% of adults overweight or obese and almost one-third of children aged 5-9 overweight.

Air pollution caused about 40 deaths per 100,000 people across OECD countries. Death rates were much higher in countries like India and China, at around 140 deaths per 100,000 people.

The report argues that more attention should be placed on patient-reported outcomes and experiences. Preliminary results from OECD’s new initiative on Patient Reported Indicator Surveys show that hip replacements improve an individual’s quality of life – mobility, activity, pain – by around 20%.

“Health systems can and must do better to improve the health of our populations. Measuring how health systems change people’s lives for the better is essential if we are to put resources where they can have most effect,” said Stefano Scarpetta, OECD Director for Employment, Labour and Social Affairs.

Africa’s energy future matters for the world

MD Staff

Published

on

Africa is set to become increasingly influential in shaping global energy trends over the next two decades as it undergoes the largest process of urbanisation the world has ever seen, according to a new report from the International Energy Agency.

Africa Energy Outlook 2019, a special in-depth study published today, finds that current policy and investment plans in African countries are not enough to meet the energy needs of the continent’s young and rapidly growing population. Today, 600 million people in Africa do not have access to electricity and 900 million lack access to clean cooking facilities.

The number of people living in Africa’s cities is expected to expand by 600 million over the next two decades, much higher than the increase experienced by China’s cities during the country’s 20-year economic and energy boom. Africa’s overall population is set to exceed 2 billion before 2040, accounting for half of the global increase over that period. These profound changes will drive the continent’s economic growth, infrastructure development and, in turn, energy demand, which is projected to rise 60% to around 1,320 million tonnes of oil equivalent in 2040, based on current policies and plans.

The new report is the IEA’s most comprehensive and detailed work to date on energy across the African continent, with a particular emphasis on sub-Saharan Africa. It includes detailed energy profiles of 11 countries that represent three-quarters of the region’s gross domestic product and energy demand, including Nigeria, South Africa, Ethiopia, Kenya and Ghana.

The report makes clear that Africa’s energy future is not predetermined. Current plans would leave 530 million people on the continent still without access to electricity in 2030, falling well short of universal access, a major development goal. But with the right policies, it could reach that target while also becoming the first continent to develop its economy mainly through the use of modern energy sources. Drawing on rich natural resources and advances in technology, the continent could by 2040 meet the energy demands of an economy four times larger than today’s with only 50% more energy.

“Africa has a unique opportunity to pursue a much less carbon-intensive development path than many other parts of the world,” said Dr Fatih Birol, the IEA’s Executive Director. “To achieve this, it has to take advantage of the huge potential that solar, wind, hydropower, natural gas and energy efficiency offer. For example, Africa has the richest solar resources on the planet but has so far installed only 5 gigawatts of solar photovoltaics (PV), which is less than 1% of global capacity.”

If policy makers put a strong emphasis on clean energy technologies, solar PV could become the continent’s largest electricity source in terms of installed capacity by 2040.

Natural gas, meanwhile, is likely to correspond well with Africa’s industrial growth drive and need for flexible electricity supply. Today, the share of gas in sub-Saharan Africa’s energy mix is the lowest of any region in the world. But that could be about to change, especially considering the supplies Africa has at its disposal: it is home to more than 40% of global gas discoveries so far this decade, notably in Egypt, Mozambique and Tanzania.

Africa’s natural resources aren’t limited to sunshine and other energy sources. It also possesses major reserves of minerals such as cobalt and platinum that are needed in fast-growing clean energy industries.

“Africa holds the key for global energy transitions, as it is the continent with the most important ingredients for producing critical technologies,” Dr Birol said. “For example, the Democratic Republic of the Congo accounts for two-thirds of global production of cobalt, a vital element in batteries, and South Africa produces 70% of the world’s platinum, which is used in hydrogen fuel cells. As energy transitions accelerate, so will demand for those minerals.”

African countries are on the front line when it comes to climate change, meaning the continent’s energy infrastructure planning must be climate resilient.

“Even though Africa has produced only around 2% of the world’s energy-related CO2 emissions to date, its ecosystems already suffer disproportionately from the effects of a changing climate,” Dr Birol said. “They are exposed to increased risks to food, health and economic security.”

By 2040, an additional half a billion people in Africa are expected to live in areas requiring some form of cooling as populations expand and average temperatures increase. Although Africa is expected to experience rapid economic growth over the next two decades, its contribution to global energy-related CO2 emissions rises to just 3% by 2040, based on current policies and plans.

For this report, the IEA developed a new scenario that analyses how the energy sector can spur Africa’s growth ambitions while also delivering key sustainable development goals by 2030, including full access to electricity and clean cooking facilities. The Africa Case is based on Agenda 2063, African leaders’ own strategic framework for the continent’s economic and industrial development. Economic growth in the Africa Case is significantly stronger over the next two decades than in the scenario based on today’s stated policies, but energy demand is lower. This is linked to an accelerated move away from the use of solid biomass (such as wood) as a fuel and to the wide application of energy efficiency policies.

The IEA has been monitoring Africa’s energy sector closely for a long time: IEA analysis of energy access issues on the continent began in 2002 and is set to expand significantly. This new report comes at an important time in the IEA’s deepening engagement with Africa. In May, the IEA and the African Union Commission co-hosted their first joint ministerial summit at which the two organisations signed a Memorandum of Understanding to guide future collaboration. A second ministerial forum will be held in 2020.

Africa Energy Outlook 2019 is an excerpt from the IEA’s flagship report World Energy Outlook 2019, which will be published in full on 13 November.

Report sheds light on regulatory reforms a decade after the global financial crisis

Newsroom

Published

on

A decade after the global financial crisis, developing countries have increased their minimum capital requirements to help improve the resilience of banking systems. However, countries are still falling short in disclosure of information and supervisory capacity to maintain a well-functioning banking sector, a new World Bank report says.

The Global Financial Development Report 2019/2020: Bank Regulation and Supervision a Decade after the Global Financial Crisis draws on ten years of data and analysis to show how the dual regulatory pillars of market discipline and capital regulation have evolved since the crisis. New data from the World Bank’s global Bank Regulation and Supervision Survey, a unique database covering regulation and supervision in 160 countries around the world, is available to the public.

In the wake of the crisis, much of the discussion on regulatory reforms has focused on advanced economies, while there is a lack of evidence on the reforms undertaken by developing countries and their impact on the stability and lending behavior of local banking sectors. The report aims to address this knowledge gap and contribute to policy discussions on bank regulation and supervision – the rules of the game and how they are enforced – which are critical for banking systems in all countries to function well.

“The right regulatory and supervisory environment is key to creating a financial system that can both attract private capital and align private incentives with the public good,” said lead author of the report, Asli Demirgüç-Kunt, World Bank Chief Economist for Europe and Central Asia. “The report shows that one size does not fit all, and less complex regulations may lead to more effective enforcement and better supervision in developing countries.”

In low-income countries, the report notes that capital ratios are particularly high, which is an encouraging sign as capital can play an important role in curbing risks and ensuring stability where supervisory capacity is low. More than 60 percent of low-income countries also have an explicit deposit insurance scheme. This means design and implementation will be crucial, since deposit insurance can lead to instability in weak institutional settings. The report emphasizes that regulations need to be designed taking into consideration a country’s institutional environment, supervisory capacity, and business model of banks.

Globally, bank regulations became more complex after the crisis, potentially reducing transparency, increasing regulatory arbitrage and taxing supervisory resources and capacity. The report analyzes two key pillars of regulatory reforms:

Market Discipline can contribute to financial stability, but major flaws were revealed by the financial crisis. Over the last decade, nearly 30 countries introduced legislation to ensure that large financial institutions can be resolved without resorting to taxpayer-funded bailouts in the event of a crisis. Still, large gaps remain. Little progress has been made to improve information disclosure about the health of banks. Deposit insurance schemes have also expanded dramatically. If designed and administered poorly, these arrangements may increase banks’ risk-taking incentives, which can lead to instability, particularly in settings with inadequate supervision.

Capital regulations are also central to managing risk. Data on 20,000 banks in 159 countries reveals that regulatory capital ratios—the ratio of capital to risk-weighted assets held by a bank—have improved since the financial crisis. However, this trend has largely been driven by a shift toward asset categories with lower risk weights, which may not adequately reflect real-world risk and could leave the financial sector vulnerable during a crisis.
