Renewable sources of electricity such as wind and solar grew at their fastest rate in two decades in 2020 and are set to expand in coming years at a much faster pace than prior to the pandemic, according to a new report by the International Energy Agency. The growth in Europe and the United States will be even brisker than previously forecast, compensating for China’s transitional slowdown after exceptional 2020 growth.

According to the IEA’s latest market update, the amount of renewable electricity capacity added in 2020 rose by 45% in 2020 to 280 gigawatts (GW), the largest year-on-year increase since 1999. That extra power is equal to the total installed capacity of ASEAN, a grouping of 10 dynamic South-East Asian economies.

The increase in 2020 is set to become the “new normal”, with about 270 GW of renewable capacity on course to be added in 2021 and almost 280 GW in 2022, despite a slowdown in China after an exceptional level of additions last year. Those forecasts have been revised upwards by more than 25% from the IEA’s previous estimates in November as governments around the world have auctioned record levels of renewable capacity and companies have signed record-level power purchase agreements, even as the pandemic spread macroeconomic uncertainties and supressed demand.

Shifting power generation to renewable sources is a key pillar of global efforts to reach carbon neutrality, but CO2 emissions are set to rise this year because of a parallel rise in coal use, underscoring the major policy changes and investments in clean energy needed to meet climate goals. 

“Wind and solar power are giving us more reasons to be optimistic about our climate goals as they break record after record. Last year, the increase in renewable capacity accounted for 90% of the entire global power sector’s expansion,” said Fatih Birol, the Executive Director of the IEA. “Governments need to build on this promising momentum through policies that encourage greater investment in solar and wind, in the additional grid infrastructure they will require, and in other key renewable technologies such as hydropower, bioenergy and geothermal. A massive expansion of clean electricity is essential to giving the world a chance of achieving its net zero goals.’’

Global wind capacity additions almost doubled last year to 114 GW. That growth will slow down a bit in 2021 and 2022, but the increases will still be 50% larger than the average expansion during the 2017-19 period. Solar PV installations will continue to break new records, with annual additions forecast to reach over 160 GW by 2022. That would be almost 50% higher than the level achieved in 2019 prior to the pandemic, affirming solar’s position as the “new king” of global electricity markets.

China is at the center of global renewable demand and supply, accounting for around 40% of global renewable capacity growth for several years. In 2020, China’s share rose to 50% for the first time due to a rush to complete projects before government subsidies were phased out. In 2021-22 renewables growth in China is set to stabilise at levels that are below the 2020 record but still over 50% above where it was during the 2017-19 period. Any slowdown in China in the coming years will be compensated for by strong growth in Europe, the United States, India and Latin America where government support and falling prices for solar PV and wind continue to drive installations.

China is the largest manufacturer of solar panels and wind turbines, as well as the biggest supplier of raw materials such as silicon, glass, steel, copper and rare earth materials needed to build them. Supply chain constraints, including due to a fire in a Chinese silicon factory last year, have recently pushed up prices of PV modules, highlighting the sector’s potential vulnerabilities in the longer term.

In the United States, renewable capacity growth this year and next is mainly spurred by the extension of federal tax credits. The forecast does not take into account the US administration’s new emissions reduction targets or its infrastructure bill. If enacted, the bill would drive a much stronger acceleration in the deployment of renewables after 2022.

India’s capacity additions declined by almost 50% last year compared with 2019. However, growth is set to rebound and renewable expansion is expected to set a new records by 2022, driven by the commissioning of delayed projects. However, the current surge in Covid‑19 cases in India has created short-term uncertainty for this year.

Transport biofuel production declined 8% globally in 2020 as the pandemic limited travel. Production is expected to recover this year to 2019 volumes, and expand another 7% in 2022 as biodiesel and hydrotreated vegetable oil (HVO) production increases globally and ethanol expands in India.

However, the ongoing effects of the Covid-19 crisis on demand, as well as price competition for sugar cane from sweetener manufacturers in Brazil, continue to keep ethanol production in both the United States and Brazil below 2019 levels. At the same time, global HVO production capacity is expected to nearly double in the next two years, significantly expanding the capability of producing biofuels from waste and residue feedstocks.

Surging electricity demand is putting power systems under strain around the world

Published

on

Global electricity demand surged in 2021, creating strains in major markets, pushing prices to unprecedented levels and driving the power sector’s emissions to a record high. Electricity is central to modern life and clean electricity is pivotal to energy transitions, but in the absence of faster structural change in the sector, rising demand over the next three years could result in additional market volatility and continued high emissions, according an IEA report released today.

Driven by the rapid economic rebound, and more extreme weather conditions than in 2020, including a colder than average winter, last year’s 6% rise in global electricity demand was the largest in percentage terms since 2010 when the world was recovering from the global financial crisis. In absolute terms, last year’s increase of over 1 500 terawatt-hours was the largest ever, according to the January 2022 edition of the IEA’s semi-annual Electricity Market Report.

The steep increase in demand outstripped the ability of sources of electricity supply to keep pace in some major markets, with shortages of natural gas and coal leading to volatile prices, demand destruction and negative effects on power generators, retailers and end users, notably in China, Europe and India. Around half of last year’s global growth in electricity demand took place in China, where demand grew by an estimated 10%. China and India suffered from power cuts at certain points in the second half of the year because of coal shortages.

“Sharp spikes in electricity prices in recent times have been causing hardship for many households and businesses around the world and risk becoming a driver of social and political tensions,” said IEA Executive Director Fatih Birol. “Policy makers should be taking action now to soften the impacts on the most vulnerable and to address the underlying causes. Higher investment in low-carbon energy technologies including renewables, energy efficiency and nuclear power – alongside an expansion of robust and smart electricity grids – can help us get out of today’s difficulties.”

The IEA’s price index for major wholesale electricity markets almost doubled compared with 2020 and was up 64% from the 2016-2020 average. In Europe, average wholesale electricity prices in the fourth quarter of 2021 were more than four times their 2015-2020 average.  Besides Europe, there were also sharp price increases in Japan and India, while they were more moderate in the United States where gas supplies were less perturbed.

Electricity produced from renewable sources grew by 6% in 2021, but it was not enough to keep up with galloping demand. Coal-fired generation grew by 9%, serving more than half of the increase in demand and reaching a new all-time peak as high natural gas prices led to gas-to-coal switching. Gas-fired generation grew by 2%, while nuclear increased by 3.5%, almost reaching its 2019 levels. In total, carbon dioxide (CO2) emissions from power generation rose by 7%, also reaching a record high, after having declined the two previous years.

“Emissions from electricity need to decline by 55% by 2030 to meet our Net Zero Emissions by 2050 Scenario, but in the absence of major policy action from governments, those emissions are set to remain around the same level for the next three years,” said Dr Birol. “Not only does this highlight how far off track we currently are from a pathway to net zero emissions by 2050, but it also underscores the massive changes needed for the electricity sector to fulfil its critical role in decarbonising the broader energy system.”

For 2022-2024, the report anticipates electricity demand growing 2.7% a year on average, although the Covid-19 pandemic and high energy prices bring some uncertainty to this outlook. Renewables are set to grow by 8% per year on average, serving more than 90% of net demand growth during this period. We expect nuclear-based generation to grow by 1% annually during the same period.

As a consequence of slowing electricity demand growth and significant renewables additions, fossil fuel-based generation is expected to stagnate in the coming years, with coal-fired generation falling slightly as phase-outs and declining competitiveness in the United States and Europe are balanced by growth in markets like China and India. Gas-fired generation is seen growing by around 1% a year.

Canada’s bold policies can underpin a successful energy transition

Published

on

Canada has embarked on an ambitious transformation of its energy system, and clear policy signals will be important to expand energy sector investments in clean and sustainable energy sources, according to a policy review by the International Energy Agency.

Since the IEA’s last in-depth review in 2015, Canada has made a series of international and domestic climate change commitments, notably setting a target to cut greenhouse gas emissions by 40-45% from 2005 levels by 2030 and a commitment to reach net zero emissions by 2050.

To support those climate and energy targets, governments in Canada have in recent years worked on a number of policy measures, including an ambitious carbon-pricing system, a clean fuels standard, a commitment to phase out unabated coal-fired electricity by 2030, nuclear plant extensions, methane regulations in the oil and gas sector, energy efficiency programmes and measures to decarbonise the transport sector.

“Canada has shown impressive leadership, both at home and abroad, on clean and equitable energy transitions,” said IEA Executive Director Fatih Birol, who is launching the report today with Jonathan Wilkinson, Canada’s Minister of Natural Resources. “Canada’s wealth of clean electricity and its innovative spirit can help drive a secure and affordable transformation of its energy system and help realise its ambitious goals. Equally important, Canada’s efforts to reduce emissions – of both carbon dioxide and methane – from its oil and gas production can help ensure its continued place as a reliable supplier of energy to the world.”

Canada’s profile as a major producer, consumer and exporter of energy presents both challenges and opportunities for reaching the country’s enhanced targets. Energy makes up 10% of gross domestic product and is a major source of capital investment, export revenue and jobs. Moreover, Canada’s highly decentralised system of government means that close coordination between federal, provincial and territorial governments is essential for a successful energy transition.

“This report acknowledges Canada’s ambitious efforts and historic investments to develop pathways to achieve net-zero emissions by 2050 and ensure a transition that aligns with our shared objective of limiting global warming to 1.5 degrees Celsius, “ said Minister Wilkinson. “These are pathways that make the most sense for our people, our economy and our country and will also yield technology, products and know-how that can be exported and applied around the world.”                              

The IEA finds that emissions intensity from Canada’s oil and gas production has declined in recent years, but the sector remains a major source of greenhouse gases, accounting for about a quarter of the country’s GHG emissions. Along with strong action to curb methane emissions, improving the rate of energy technology innovation will be essential for the deep decarbonisation that is needed in oil and gas production, as well as in the transport and industry sectors. Canada is actively advancing innovation in a number of key fields, including carbon capture, utilisation and storage; clean hydrogen; and small modular nuclear reactors, with a view to serving as a supplier of energy and climate solutions to the world. The IEA notes that further federal support for research, development and demonstration would help accelerate progress towards these goals.

The IEA is also recommending that Canada’s federal government promote a comprehensive energy efficiency strategy in consultation with provinces and territories that sets clear targets for energy efficiency in the buildings, industry and transport sectors

The IEA report highlights that Canada’s electricity supply is among the cleanest in the world, with over 80% of supply coming from non-emitting sources, thanks to the dominance of hydro and the important role of nuclear. To further support the expansion of clean power and electrification, the report encourages increased interconnections among provinces and territories to ensure balanced decarbonisation progress across the country.

The IEA commends Canada on its efforts to advance a people-centred approach to its clean energy transition, including initiatives to promote diversity and inclusion in clean energy sectors; programmes to increase access to clean energy in northern, remote and Indigenous communities; and actions to enable just transitions for coal workers and their communities.

“Canada has laid out a comprehensive set of policy measures and investments across sectors to meet its climate targets, including a strong clean energy component to its Covid-19 economic recovery efforts,” said Dr Birol. “I hope this report will help Canada navigate its path toward economy-wide emissions reductions and a net zero future.”

Iran to add 10GW to renewable energy capacity

Published

on

Iranian Energy Ministry and some of the country’s private contractors signed memorandums of understanding (MOU) on Sunday for cooperation in the construction of renewable power plants to generate 10,000 megawatts (10 gigawatts) of electricity across the country.

The signing ceremony was attended by senior energy officials including Energy Minister Ali-Akbar Mehrabian and Head of Renewable Energy and Energy Efficiency Organization (SATBA) Mahmoud Kamani, IRIB reported.

The MOUs were signed following the Energy Ministry’s public call for the contribution of private companies in a project for developing renewable power plants in the country.

According to SATBA, after the ministry’s public call, so far 153 requests for the generation of 90,000 megawatts (MW) have been submitted to the ministry by private companies.

Speaking in the signing ceremony, Energy Minister Ali-Akbar Mehrabian said: “When the private sector invests in this industry [the renewables], the government is obliged to return the equivalent of the investment plus its interests to the investor.”

Mehrabian noted that the government has allocated over 30 trillion rials (about $101 million) for the development of renewables in the budget bill for the next Iranian calendar year (begins on March 21), saying that it is an unprecedented budget in this area.

Further in the ceremony, SATBA Head Kamani mentioned some of the Energy Ministry’s plans for the development of the country’s renewable energy industry, saying: “Export of renewable energy is a goal that has been targeted by the government.”

“Constructing renewable power plants for the cryptocurrency miners is also being seriously considered,” he added.

Back in December 2021, Kamani had announced plans to create 10,000 MW capacity of new renewable power plants across the country within the next four years.

He had put the current capacity of the country’s renewable power plants at 905 MW, saying that such power plants account only for one percent of the country’s total power generation capacity.

“Currently, 30 percent of the world’s electricity needs are provided by renewable energy sources, and some countries have even declared 2030 as the final year of using fossil fuels,” he said.

“We are far behind the global standards in the development of renewable energy,” he regretted.

Referring to another program for the development of renewable energies in the domestic sector, Kamani noted that to encourage households for constructing such power plants the Energy Ministry has announced that it will buy their surplus generated electricity at a guaranteed price.

He further pointed to the indigenization of the knowledge for the construction of the equipment used in renewable power plants as another priority of the Energy Ministry and SATBA, saying: “Currently, the construction of solar panels and wind power plants is completely indigenized, and we must strengthen our producers to finally become able to build all the required equipment from start to finish, in this regard, of course, some enterprises have announced their readiness.”
