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.
COVID-19 has reshaped last-mile logistics, with e-commerce deliveries rising 25% in 2020
COVID-19 has shifted the way people buy goods, accelerating the rise in online shopping and e-commerce deliveries. According to a new report from the World Economic Forum, this has led to a 25% rise in consumer e-commerce deliveries in 2020.
The new report, Pandemic, Parcels and Public Vaccination: Envisioning the Next Normal for the Last-Mile Ecosystem, explores changes seen over the last year which will greatly influence last mile deliveries in the future. For example, it’s expected that 10%-20% of the recent increase in e-commerce deliveries will continue after the pandemic and the lifting of COVID-19 restrictions.
“Covid-19 shutdowns have completely reshaped how we live and of course this includes how and what we’re buying,” said Christoph Wolff, Head of Mobility, World Economic Forum. “Leaders must consider and respond to the effects COVID-19 has had on e-commerce deliveries and what impact these changes will have on their cities and communities.”
Beyond rising demand, the past year has also seen a large shift to greener delivery options, with wider spread EV across the industry and more stringent carbon emission rules from cities expected to shape delivery networks in the near future.
Overall, the report finds six main structural changes to the delivery and logistics sector that are expected to last:
Six structural changes
The pandemic has caused an increase in last-mile deliveries that are likely to persist.
In 2020, business-to-consumer parcel deliveries have risen by about 25%. The report suggests that part of this increased demand will be durable, with at least 10%-20% of the growth remaining post-pandemic.
Consumers increasingly buy new types of products online and consider environmental and health impact when buying.
As consumers continue to buy a wider array of goods online, they are also becoming more ecologically aware. For example, 56% of millennials cite environmental protection as the reason for choosing alternatives to home delivery.
Decarbonization of last-mile deliveries has accelerated.
Companies and cities have ramped up commitments to make emission-free deliveries, while many pandemic-related economic stimulus packages, especially in the European Union and China, contain provisions to support green mobility and goods transport.
Faced with budget challenges and increased transport needs, cities steer last-mile transitions.
Many cities, like Seattle and Boston, have started to repurpose kerb space to designated delivery pick-up. Others, including Santa Monica and Amsterdam, are taking bold action on cleaner delivery with “zero-emission delivery zones” and electric vehicle charging infrastructure.
Proven technologies are fuelling the last-mile ecosystem revolution.
While disruptive new technologies, such as drones and delivery robots, will continue to emerge, the last-mile revolution is happening now as proven technologies scale up. The likes of parcel lockers and data sharing for load pooling are being adopted around the world as the costs of implementation decrease
New business models emerge to meet increased demand for sustainable delivery vehicles.
Certain logistics companies are now offering services to online retailers, which will help them identify the delivery routes most suited to make the immediate transition to electric delivery vehicles.
Last mile for vaccines
While ensuring equitable access to COVID-19 vaccines remains the most pressing issue in global vaccine distribution, effective last-mile delivery is another critical issue for countries. The key challenges are cold storage, second vaccine dose needs, and a disconnect between the vaccine and patient journey.
“Governments and logistics companies could think about teaming up with players who are experienced in managing very local, capillary demand and with integrating a large number of local retail outlets,” says Anja Huber, Engagement Manager, McKinsey & Company. “Examples include large online retailers, eGrocery giants and technology platform players”
Potential solutions countries can implement for efficient vaccine delivery include real-time logistics planning, data integration, centralized management of delivery strategies at the national level and many more.
There are also early examples of countries that have handled this challenge particularly well. While there are many factors in vaccine distribution success, broadly speaking, countries with tight integration of healthcare and logistics stakeholders seem to show the highest national vaccination rates two months into 2021.
These include Israel, the UK and Chile outperforming other countries with more decentralized healthcare systems, like the US and Germany, which had slower initial vaccine rollouts.
Clearly, much still needs to be done to ensure developed countries overcome operational issues with vaccine delivery. However, mobility solutions should not overshadow an even larger ethical challenge in the differences of vaccine access between the global north and global south, which is a priority for greater equity.
Future of the last mile
The impact of COVID-19 on the last-mile delivery has accelerated existing trends across the sector, leading to six structural changes expected to shape the future of last mile deliveries.
These will be part of a broader urban mobility transition, driven by public policy and company actions. As cities and logistics leaders continue the sustainable urban delivery transition, close public-private coordination will be critical. Zero Emissions Urban Fleets (ZEUF) network, for example, provides a relevant dedicated stakeholder platform for this work.
Asian Ports Dominate Global Container Port Performance Index
Asian container ports are the most efficient in the world, dominating the Top 50 spots according to the new global Container Port Performance Index (CPPI) launched by the World Bank and IHS Markit. The report scored ports against different metrics, making the efficiency ranking comparable around the globe by assessing and standardizing for different ship sizes and container moves per call. The CPPI is intended to identify gaps and opportunities for improvement that will benefit stakeholders from shipping lines to national governments to consumers.
More than four-fifths of global merchandise trade by volume are carried by sea, and approximately 35 percent of total volumes and over 60 percent of commercial value is shipped in containers.
“The development of high-quality and efficient container port infrastructure is a key contributor to successful, export-led growth strategies both in developing and developed countries”, said Martin Humphreys, Lead Transport Economist and Global Lead for Transport Connectivity and Regional Integration in the World Bank. “Efficient ports also ensure business continuity and improve the resilience of the maritime gateways as crucial nodes in the global logistical system.”
“Inefficient port operations have a very direct impact on supplies across the country and their populations. During the COVID-19 pandemic we saw port delays causing shortages of essential goods and higher prices. Over the longer term such bottlenecks can mean slower economic growth, higher costs for importers and exporters and even resulting in less employment,” added Turloch Mooney, Associate Director, Maritime and Trade at IHS Markit.
East Asian ports dominate the CPPI, led by Yokohama in Japan ahead of King Abdullah Port in Saudi Arabia and Qingdao in China.Algeciras in Spain is the highest ranked European port, in 10th place. Colombo in Sri Lanka is the top-ranked port in South Asia at 17th place and Mexico’s Lazaro Cardenas leads the Americas at 25th. Canada’s Halifax is the only other North American port in the Top 50. Djibouti, in 61st place, is the top-ranked African port.
Key port performance metrics such as minutes per container move show large discrepancies in global port efficiency, with top performers such as Yokohama taking just 1.1 minutes on average to load or unload a container in a standard port call while the average for equivalent workloads in African ports is more than three times that at 3.6 minutes.
The Container Port Performance Index is based on total port hours per ship call, defined as the elapsed time between when a ship reaches a port to its departure from the berth having completed its cargo exchange. Greater or lesser workloads are accounted for by examining the underlying data within ten different call size ranges. Five distinct ship size groups are accounted for in the methodology given the potential for greater fuel and emissions savings on larger vessels.
Labour market disruption & COVID-19 support measures contribute to widespread falls in taxes
The COVID-19 crisis has resulted in the largest decrease in taxes on wages since the global financial crisis of 2008-09, according to a new OECD report.
Taxing Wages 2021 shows that declining household incomes coupled with tax reforms linked to the pandemic are driving widespread declines in effective taxes on wages across the OECD.
The report highlights record falls across the OECD during 2020 in the tax wedge – the total taxes on labour paid by both employees and employers, minus family benefits, as a percentage of the labour cost to the employer.
The tax wedge for a single worker at the average wage was 34.6% in 2020, a decrease of 0.39 percentage points from the previous year. This is a significant fall, but is smaller than the decreases seen in the global financial crisis – 0.48 percentage point in 2008, and 0.52 percentage points in 2009. The tax wedge increased in 7 of the 37 OECD countries over the 2019-20 period and fell in 29, mainly due to lower income taxes.
The drop in the tax wedge was even more significant for households with children, bringing tax rates on these family types to new lows. The average tax wedge for a one-earner couple at the average wage with children in 2020 was 24.4%, a decrease of 1.1 percentage points versus 2019. This is the largest fall and lowest level seen for this household type since the OECD started producing Taxing Wages in 2000.
Between 2019 and 2020, the tax wedge for this household type decreased in 31 countries, and rose in only 6. It decreased by more than 1 percentage point in 16 countries. The largest decreases were in Lithuania, the United States, Poland, Italy, Canada and Korea. The only increase over 1 percentage point was in New Zealand.
The gap between the OECD average tax wedge for the single average worker (34.6%) and the one-earner couple with children (24.4%) has widened by 0.7 percentage points since 2019, reflecting policy changes that provided additional support to families with children during the COVID-19 crisis.
The falls in country tax wedges for the single worker, the one-earner couple with two children, and the single parent resulted predominantly from changes in tax policy settings, although falling average wages also contributed in some countries. By contrast, increases in the tax wedge were almost all driven by rising average wages, offset only slightly by policy changes.
Of the ten countries where specific COVID-19 measures affected the indicators, support was primarily delivered through enhanced or one-off cash benefits, with a focus on supporting families with children.
The report shows that labour taxation continues to vary considerably across the OECD, with the tax wedge on the average single worker ranging from zero in Colombia to 51.5% in Belgium.
