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

Published

on

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.

Archipelagic Economies: Spatial Economic Development in the Pacific

Published

on

A new World Bank report on the challenges facing the Pacific region’s outer island communities identifies investment in people and livelihoods as a key for inclusive economic growth.    

Archipelagic Economies: Spatial Economic Development in the Pacific looks at the challenges Pacific governments must address to provide services and infrastructure to populations spread across hundreds of islands spanning the vast Pacific Ocean. The report puts forward a series of practical steps that countries can take to overcome these challenges in a way that supports resilient and inclusive economic growth.

“Many Pacific countries are faced with significant challenges in delivering services and connecting remote, outer island communities; with difficult decisions around resources and how to best invest often limited resources into outer island communities,” said the report’s lead author, World Bank Lead Economist for Fiscal Policy and Sustainable Growth Robert Utz.

“This report aims to provide Pacific governments, development partners and decision-makers with evidence to assess options for fostering development for the people in those outer islands, so they can make stronger contributions to the larger economic development of the whole country.”   

The report identifies six guiding economic policy principles:

1)     Policy solutions that seek to achieve equitable increases in living standards need to be grounded in an understanding of the economic implications of the Pacific region’s unique economic geography.

2)     Outer islands’ development should be assessed from a spatial perspective; one that considers interactions with the country’s main island and the region beyond.

3)     A balanced approach that combines investments in urban areas to accommodate migration from outer islands to main islands with support for outer island populations is likely to achieve better welfare and equity outcomes than an approach that neglects one side or the other.

4)     Growth-enhancing investments should be guided by clearly-identified opportunities, rather than by a desire to try to equalize economic opportunities across islands.

5)     With limited scope to close the gap in economic opportunities between outer and main islands investments to promote livelihoods and human development should be given preference.

6)     Outer islands are subject to a complex political economy of intra-island and outer island-main island relationships that need to be considered in development interventions.

“This is an important and timely study,” said Denton Rarawa, Senior Economic Advisor at the Pacific Islands Forum Secretariat. “The current COVID-19 crisis has highlighted the need to address the institutional, service delivery and capacity gaps of nations across the Pacific. As we strive for greater vaccination rates and begin to think about how we’d like to rebuild after the pandemic, I believe this report has a lot to offer the future of the Pacific, especially in our efforts to leave no one behind.”   

The Archipelagic Economies report is a companion publication to the World Bank’s Pacific Possible series, which in 2017 and 2018 looked at opportunities for economic growth in Pacific Islands Countries across key sectors including tourism, fisheries, and labour mobility. 

The World Bank works in partnership with 12 countries across the Pacific, supporting 87 projects totaling US$2.09 billion in commitments in sectors including agriculture, aviation and transport, climate resilience and adaptation, economic policy, education and employment, energy, fisheries, health, macroeconomic management, rural development, telecommunications and tourism.

Global economic recovery continues but remains uneven

Published

on

The global economy is growing far more strongly than anticipated a year ago but the recovery remains uneven, exposing both advanced and emerging markets to a range of risks, according to the OECD’s latest Interim Economic Outlook.

The OECD says extraordinary support from governments and central banks helped avoid the worst once the COVID-19 pandemic hit. With the vaccine roll-out continuing and a gradual resumption of economic activity underway, the OECD projects strong global growth of 5.7% this year and 4.5% in 2022, little changed from its May 2021 Outlook of 5.8% and 4.4% respectively.

Countries are emerging from the crisis with different challenges, often reflecting their pre-COVID 19 strengths and weaknesses, and their policy approaches during the pandemic. Even in the countries where output or employment have recovered to their pre-pandemic levels, the recovery is incomplete, with jobs and incomes still short of the levels expected before the pandemic.

Large differences in vaccination rates between countries are adding to the unevenness of the recovery. Renewed outbreaks of the virus are forcing some countries to restrict activities, resulting in bottlenecks and adding to supply shortages.  

There is a marked variation in the outlook for inflation, which has risen sharply in the US and some emerging market economies but remains relatively low in many other advanced economies, particularly in the euro area.

A rapid increase in demand as economies reopen has pushed up prices in key commodities such as oil and metals as well as  food, which has a stronger effect on inflation in emerging markets. The disruption to supply chains caused by the pandemic has added to cost pressures. At the same time, shipping costs have increased sharply.

But the Interim Outlook says that these inflationary pressures should eventually fade. Consumer price inflation in the G20 countries is projected to peak towards the end of 2021 and slow throughout 2022. Wage growth remains broadly moderate and medium-term inflation expectations remain contained.

The report warns that to keep the recovery on track stronger international efforts are needed to provide low-income countries with the resources to vaccinate their populations, both for their own and global benefits.

Macroeconomic policy support is still needed as long as the outlook is uncertain and employment has not yet recovered fully, but clear guidance is called upon from policymakers to minimise risks looking forward. Central banks should communicate clearly about the likely sequencing of moves towards eventual policy normalisation and the extent to which any overshooting of inflation targets will be tolerated. The report says fiscal policies should remain flexible and avoid a premature withdrawal of support, operating within credible and transparent medium-term fiscal frameworks that provide space for stronger public infrastructure investment.

Presenting the Interim Economic Outlook alongside Chief Economist Laurence Boone, OECD Secretary-General Mathias Cormann said: “The world is experiencing a strong recovery thanks to decisive action taken by governments and central banks at the height of the crisis. But as we have seen with vaccine distribution, progress is uneven. Ensuring the recovery is sustained and widespread requires action on a number of fronts – from effective vaccination programmes across all countries to concerted public investment strategies to build for the future.”

Ms Boone said: “Policies have been efficient in buffering the shock and ensuring a strong recovery; planning for more efficient public finances, shifted towards investment in physical and human capital is necessary and will help monetary policy to normalise smoothly once the recovery is firmly established.”

Financing Options Key to Africa’s Transition to Sustainable Energy

Published

on

A new whitepaper outlining the key considerations in setting the course for Africa’s energy future was released today at the 2021 Sustainable Development Impact Summit. The report, “Financing the Future of Energy,” outlines Africa’s electricity landscape and financing options in context with the global drive to reduce carbon emissions.

Africa’s power sector will play a central role in the transition from fossil fuel-driven power generation to a renewable-strong energy mix. According to the whitepaper written in collaboration with Deloitte, the migration to a multi-stakeholder-oriented net-zero power grid is being driven by “the 3Ds:”

  • Decarbonization: moving from fossil fuel sources to renewables
  • Decentralization: Shifting from centrally managed generation, transmission, and distribution to decentralized systems
  • Digitalization: Leveraging digital technology to advance the transition

The report contends that new coalitions and investments with developed nations and NGOs including the World Economic Forum must coordinate and enable countries to leapfrog existing technologies and infrastructure.

“The need for digitally smarter utility platforms and sustainable development programs will guide global leaders in helping to shape equitable and inclusive recovery programs,” said Chido Munyati, Head of Africa at the World Economic Forum. “The entire continent remains vulnerable, but this whitepaper offers a view on what are viable financing options that exist today for clean energy sustainability and equitable recovery for all of Africa.

Funding will be the biggest hurdle to ensuring Africa’s sustainable transition to Renewables at scale; there are many financing solutions available,” said Mario Fernandes, Director, Africa Power Utilities and Renewables, Deloitte. “Africa’s winners will be the ones that are able to leverage what exists while creating an enabling environment for the private sector through a Renewables Energy Investment facility.”

Case studies in China and India showed that financing solutions for a clean energy transition often involve long cycles. Economic booms in these countries resulted in a significant shift in carbon emissions. Since similar economic booms are expected across Africa, the report highlights how crucial it is to anchor growth in technologies that can enable lower emissions.

While Africa’s contribution to greenhouse gas emissions from fossil fuel significantly lags behind those of other continents, it still carries a huge potential to accelerate the transition to a net-zero future. Currently, half of the continent lives without adequate access to electricity. As energy demands increase, the energy gap could be bridged through clean energy alternatives, if the financing solutions are employed now.
