Infrastructure needs $15 billion annually: study

Renewables 2020 Global Status Report highlights renewable energy gaps beyond power, urging decarbonization in heating, cooling, and transport, greener COVID-19 recovery, market reforms, and rapid energy transition to cut CO2 emissions and fossil fuel dependence.

Key Points

REN21's annual report on renewable energy progress and policy gaps across power, heating, cooling, and transport.

✅ Calls for decarbonizing heating, cooling, and transport.

✅ Warns COVID-19 recovery must avoid fossil fuel lock-in.

✅ Urges market reforms to boost energy efficiency and renewables.

Growth in renewable power has been impressive over the past five years, with over 30% of global electricity now coming from renewables worldwide. But too little is happening in heating, cooling and transport. Overall, global hunger for energy keeps increasing and eats up progress, according to REN21's Renewables 2020 Global Status Report (GSR), released today. The journey towards climate disaster continues, unless we make an immediate switch to efficient and renewable energy in all sectors in the wake of the COVID-19 pandemic.

"Year after year, we report success after success in the renewable power sector. Indeed, renewable power has made fantastic progress. It beats all other fuels in growth and competitiveness. Many national and global organisations already cry victory. But our report sends a clear warning: The progress in the power sector is only a small part of the picture. And it is eaten up as the world's energy hunger continues to increase. If we do not change the entire energy system, we are deluding ourselves," says Rana Adib, REN21's Executive Director.

The report shows that in the heating, cooling and transport sectors, the barriers are still nearly the same as 10 years ago. "We must also stop heating our homes and driving our cars with fossil fuels," Adib claims.

There is no real disruption in the COVID-19 pandemic

In the wake of the extraordinary economic decline due to COVID-19, the IEA predicts energy-related CO2 emissions are expected to fall by up to 8% in 2020. But 2019 emissions were the highest ever, and the relief is only temporary. Meeting the Paris targets would require an annual decrease of at least 7.6% to be maintained over the next 10 years, and UN analysis on NDC ambition underscores the need for faster action. Says Adib: "Even if the lock-downs were to continue for a decade, the change would not be sufficient. At the current pace, with the current system and current market rules, it would take the world forever to come anywhere near a no-carbon system."

"Many recovery packages lock us into a dirty fossil fuel economy"

Recovery packages offer a once-in-a-lifetime chance to make the shift to a low-carbon economy, and green energy investments could accelerate COVID-19 recovery. But according to Adib there is a great risk for this enormous chance to be lost. "Many of these packages include ideas that will instead lock us further into a dirty fossil fuel system. Some directly promote natural gas, coal or oil. Others, though claiming a green focus, build the roof and forget the foundation," she says. "Take electric cars and hydrogen, for example. These technologies are only green if powered by renewables."

Choosing an energy system that supports job creation and social justice

The report points out that "green" recovery measures, such as investment in renewables and building efficiency, are more cost-effective than traditional stimulus measures and yield more returns. It also documents that renewables deliver on job creation, energy sovereignty, accelerated energy access in developing countries, and clean, affordable and sustainable electricity for all objectives worldwide, alongside reduced emissions and air pollution.

"Renewables are now more cost-effective than ever, and recent IRENA analysis shows their potential to decarbonise the energy sector, providing an opportunity to prioritize clean economic recovery packages and bring the world closer to meeting the Paris Agreement Goals. Renewables are a key pillar of a healthy, safe and green COVID-19 recovery that leaves no one behind," said Inger Andersen, Executive Director of the UN Environment Programme (UNEP). "By putting energy transition at the core of economic recovery, countries can reap multiple benefits, from improved air quality to employment generation."

This contrasts with the true cost of fossil fuels, estimated to be USD 5.2 trillion if costs of negative impacts such as air pollution, effects of climate change, and traffic congestion are counted.

Renewable energy systems support energy sovereignty and democracy, empowering citizens and communities, instead of big fossil fuel producers and consumers. "When spending stimulus money, we have to decide: Do we want an energy system that serves some or a system that serves many?", says Adib. "But it's not only about money. We must end any kind of support to the fossil economy, particularly when it comes to heating, cooling and transport. Governments need to radically change the market conditions and rules and demonstrate the same leadership as during the COVID-19 pandemic."

The report finds:

Total final energy demand continues to be on the rise (1.4% annually from 2013 to 2018). Despite significant progress in renewable power generation, the share of renewables in total final energy demand barely increased (9.6% in 2013 to 11% in 2018). Compared to the power sector, the heating, cooling and transport sectors lag far behind (renewable energy share in power, 26%, heating and cooling, 10%, transport, 3%).

Today's progress is largely the result of policies and regulations initiated years ago and focus on the power sector. Major barriers seen in heating, cooling and transport are still almost the same a decade on. Policies are needed to create the right market conditions.

The renewable energy sector employed around 11 million people worldwide in 2018

In 2019, the private sector signed power purchase agreements (PPAs) for a record growth of over 43% from 2018 to 2019 in new renewable power capacity.

The global climate strikes have reached unprecedented levels with millions of people across 150 countries. They have pushed governments to step up climate ambitions. As of April 2020, 1490 jurisdictions - spanning 29 countries and covering 822 million citizens - had issued "climate emergency" declarations, many of which include plans and targets for more renewable-based energy systems.

While some countries are phasing out coal, examples such as Europe's green surge show how renewables can soar as emissions fall, yet others continued to invest in new coal-fired power plants. In addition, funding from private banks for fossil fuel projects has increased each year since the signing of the Paris Agreement, totaling USD 2.7 trillion over the last three years.

"It is clear, renewable power has become mainstream and that is great to see. But the progress in this one sector should not lead us to believe that renewables are a guaranteed success. Governments need to take action beyond economic recovery packages. They also need to create the rules and the environment to switch to an efficient and renewables-based energy system, and action toward 100% renewables is urgently needed worldwide. Globally. Now." concludes Arthouros Zervos, President of REN21.

Polycrystalline Tin Selenide Thermoelectrics enable waste heat recovery with ZT 3.1, matching single crystals while cutting costs, powering greener car engines, industrial furnaces, and thermoelectric generators via p-type and emerging n-type designs.

Key Points

Low-cost tin selenide devices that turn waste heat into power, achieving ZT 3.1 and enabling p-type and n-type modules.

✅ Oxygen removal prevents heat-leaking tin oxide grain skins.

✅ Polycrystalline ingots match single-crystal ZT 3.1 at lower cost.

✅ N-type tin selenide in development to pair with p-type.

So-called thermoelectric generators turn waste heat into electricity without producing greenhouse gas emissions, providing what seems like a free lunch. But despite helping power the Mars rovers, the high cost of these devices has prevented their widespread use. Now, researchers have found a way to make cheap thermoelectrics that work just as well as the pricey kind. The work could pave the way for a new generation of greener car engines, industrial furnaces, and other energy-generating devices.

“This looks like a very smart way to realize high performance,” says Li-Dong Zhao, a materials scientist at Beihang University who was not involved with the work. He notes there are still a few more steps to take before these materials can become high-performing thermoelectric generators. However, he says, “I think this will be used in the not too far future.”

Thermoelectrics are semiconductor devices placed on a hot surface, like a gas-powered car engine or on heat-generating electronics using thin-film converters to capture waste heat. That gives them a hot side and a cool side, away from the hot surface. They work by using the heat to push electrical charges from one to the other, a process of turning thermal energy into electricity that depends on the temperature gradient. If a device allows the hot side to warm up the cool side, the electricity stops flowing. A device’s success at preventing this, as well as its ability to conduct electrons, feeds into a score known as the figure of merit, or ZT.

 Over the past 2 decades, researchers have produced thermoelectric materials with increasing ZTs, while related advances such as nighttime solar cells have broadened thermal-to-electric concepts. The record came in 2014 when Mercouri Kanatzidis, a materials scientist at Northwestern University, and his colleagues came up with a single crystal of tin selenide with a ZT of 3.1. Yet the material was difficult to make and too fragile to work with. “For practical applications, it’s a non-starter,” Kanatzidis says.

So, his team decided to make its thermoelectrics from readily available tin and selenium powders, an approach that, once processed, makes grains of polycrystalline tin selenide instead of the single crystals. The polycrystalline grains are cheap and can be heated and compressed into ingots that are 3 to 5 centimeters long, which can be made into devices. The polycrystalline ingots are also more robust, and Kanatzidis expected the boundaries between the individual grains to slow the passage of heat. But when his team tested the polycrystalline materials, the thermal conductivity shot up, dropping their ZT scores as low as 1.2.

In 2016, the Northwestern team discovered the source of the problem: an ultrathin skin of tin oxide was forming around individual grains of polycrystalline tin selenide before they were pressed into ingots. And that skin acted as an express lane for the heat to travel from grain to grain through the material. So, in their current study, Kanatzidis and his colleagues came up with a way to use heat to drive any oxygen away from the powdery precursors, leaving pristine polycrystalline tin selenide, whereas other devices can generate electricity from thin air using ambient moisture.

The result, which they report today in Nature Materials, was not only a thermal conductivity below that of single-crystal tin selenide but also a ZT of 3.1, a development that echoes nighttime renewable devices showing electricity from cold conditions. “This opens the door for new devices to be built from polycrystalline tin selenide pellets and their applications to be explored,” Kanatzidis says.

Getting through that door will still take some time. The polycrystalline tin selenide the team makes is spiked with sodium atoms, creating what is known as a “p-type” material that conducts positive charges. To make working devices, researchers also need an “n-type” version to conduct negative charges.

Zhao’s team recently reported making an n-type single-crystal tin selenide by spiking it with bromine atoms. And Kanatzidis says his team is now working on making an n-type polycrystalline version. Once n-type and p-type tin selenide devices are paired, researchers should have a clear path to making a new generation of ultra-efficient thermoelectric generators. Those could be installed everywhere from automobile exhaust pipes to water heaters and industrial furnaces to scavenge energy from some of the 65% of fossil fuel energy that winds up as waste heat.

SM-1A Nuclear Plant Decommissioning details the US Army Corps of Engineers' removal of the Fort Greely reactor, Cold War facility dismantling, environmental monitoring, remote-site power history, and timeline to 2026 under a deactivated nuclear program.

Key Points

Army Corps plan to dismantle Fort Greely's SM-1A reactor and complete decommissioning of remaining systems by 2026.

✅ Built for remote Arctic radar support during the Cold War

✅ High costs beat diesel; program later deemed impractical

✅ Reactor parts removed; residuals monitored; removal by 2026

The US Army Corps of Engineers has begun decommissioning Alaska’s only nuclear power plant, SM-1A, which is located at Fort Greely, even as new US reactors continue to take shape nationwide. The $17m plant closed in 1972 after ten years of sporadic operation. It was out of commission from 1967 to 1969 for extensive repairs. Much of has already been dismantled and sent for disposal, and the rest, which is encased in concrete, is now to be removed.

The plant was built as part of an experimental programme to determine whether nuclear facilities, akin to next-generation nuclear concepts, could be built and operated at remote sites more cheaply than diesel-fuelled plants.

"The main approach was to reduce significant fuel-transportation costs by having a nuclear reactor that could operate for long terms, a concept echoed in the NuScale SMR safety evaluation process, with just one nuclear core," Brian Hearty said. Hearty manages the Army Corps of Engineers’ Deactivated Nuclear Power Plant Program.

He said the Army built SM-1A in 1962 hoping to provide power reliably at remote Arctic radar sites, where in similarly isolated regions today new US coal plants may still be considered, intended to detect incoming missiles from the Soviet Union at the height of the Cold War. He added that the programme worked but not as well as Pentagon officials had hoped. While SM-1A could be built and operated in a cold and remote location, its upfront costs were much higher than anticipated, and it costs more to maintain than a diesel power plant. Moreover, the programme became irrelevant because of advances in Soviet rocket science and the development of intercontinental ballistic missiles.

Hearty said the reactor was partially dismantled soon after it was shut down. “All of the fuel in the reactor core was removed and shipped back to the Atomic Energy Commission (AEC) for them to either reprocess or dispose of,” he noted. “The highly activated control and absorber rods were also removed and shipped back to the AEC.”

The SM-1A plant produced 1.8MWe and 20MWt, including steam, which was used to heat the post. Because that part of the system was still needed, Army officials removed most of the nuclear-power system and linked the heat and steam components to a diesel-fired boiler. However, several parts of the nuclear system remained, including the reactor pressure vessel and reactor coolant pumps. “Those were either kept in place, or they were cut off and laid down in the tall vapour-containment building there,” Hearty said. “And then they were grouted and concreted in place.” The Corps of Engineers wants to remove all that remains of the plant, but it is as yet unclear whether that will be feasible.

Meanwhile, monitoring for radioactivity around the facility shows that it remains at acceptable levels. “It would be safe to say there’s no threat to human health in the environment,” said Brenda Barber, project manager for the decommissioning. Work is still in its early stages and is due to be completed in 2026 at the earliest. Barber said the Corps awarded the $4.6m contract in December to a Virginia-based firm to develop a long-range plan for the project, similar in scope to large reactor refurbishment efforts elsewhere. Among other things, this will help officials determine how much of the SM-1A will remain after it’s decommissioned. “There will still be buildings there,” she said. “There will still be components of some of the old structure there that may likely remain.”

UK Smart Export Guarantee enables households to sell surplus solar energy to suppliers, with dynamic export tariffs, grid payments, and battery-friendly incentives, boosting local renewable generation, microgeneration uptake, and decarbonisation across Britain.

Key Points

UK Smart Export Guarantee pays homes for exporting surplus solar power to the grid via supplier tariffs.

✅ Suppliers must pay households for exported kWh.

✅ Dynamic tariffs incentivize daytime solar generation.

✅ Batteries boost self-consumption and grid flexibility.

Britain’s biggest energy companies will have to buy renewable energy from their own customers through community-generated green electricity models under new laws to be introduced this week.

Homeowners who install new rooftop solar panels from 1 January 2020 will be able to lower their bills as many seek to cut soaring bills by selling the energy they do not need to their supplier.

A record was set at noon on a Friday in May 2017, when solar energy supplied around a quarter of the UK’s electricity, and a recent award that adds 10 GW of renewables indicates further growth.

However, solar panel owners are not always at home on sunny days to reap the benefit. The new rules will allow them to make money if they generate electricity for the grid.

Some 800,000 householders with solar panels already benefit from payments under a previous scheme. However, the subsidies were controversially scrapped by the government in April, with similar reduced credits for solar owners seen in other regions, causing the number of new installations to fall by 94% in May from the month before.

Labour accused the government last week of “actively dismantling” the solar industry. The sector will still struggle this summer as the change does not come in for another seven months, so homeowners have no incentive to buy panels this year.

Chris Skidmore, the minister for energy and clean growth, said the government wanted to increase the number of small-scale generators without adding the cost of subsidies to energy bills. “The future of energy is local and the new smart export guarantee will ensure households that choose to become green energy generators will be guaranteed a payment for electricity supplied to the grid,” he said. The government also hopes to encourage homes with solar panels to install batteries to help manage excess solar power on networks.

Greg Jackson, the founder of Octopus Energy, said: “These smart export tariffs are game-changing when it comes to harnessing the power of citizens to tackle climate change”.

A few suppliers, including Octopus, already offer to buy solar power from their customers, often setting terms for how solar owners are paid that reflect market conditions.

“They mean homes and businesses can be paid for producing clean electricity just like traditional generators, replacing old dirty power stations and pumping more renewable energy into the grid. This will help bring down prices for everyone as we use cheaper power generated locally by our neighbours,” Jackson said.

Léonie Greene, a director at the Solar Trade Association, said it was “vital” that even “very small players” were paid a fair price. “We will be watching the market like a hawk to see if competitive offers come forward that properly value the power that smart solar homes can contribute to the decarbonising electricity grid,” she said.

NDC Renewable Energy Ambition drives COP25 calls to align with the Paris Agreement, as IRENA urges 2030 targets toward 7.7 TW, accelerating decarbonization, energy transition, socio-economic benefits, and scalable renewables in Nationally Determined Contributions.

Key Points

Raised 2030 renewable targets in NDCs to meet Paris goals, reaching 7.7 TW efficiently and speeding decarbonization.

✅ Double current NDC renewables to align with 7.7 TW by 2030

✅ Cost effective pathway with jobs, growth, welfare gains

✅ Accelerates decarbonization and energy access per UN goals

We need an oracle to get us out of this debacle. The UN climate group has met for the 25th time. Will anything ever change?

Countries are being urged to significantly raise renewable energy ambition and adopt targets to transform the global energy system in the next round of Nationally Determined Contributions (NDCs), according to a new IRENA report by the International Renewable Energy Agency (IRENA) that will be released at the UN Climate Change Conference (COP25) in Madrid.

The report will show that renewable energy ambition within NDCs would have to more than double by 2030 to put the world in line with the Paris Agreement goals, cost-effectively reaching 7.7 terawatts (TW) of globally installed capacity by then. Today’s renewable energy pledges under the NDCs are falling short of this, targeting only 3.2 TW, even as over 30% of global electricity is already generated from renewables.

The reportNDCs in 2020: Advancing Renewables in the Power Sector and Beyondwill be released at IRENA’s official side event on enhancing NDCs and raising ambition on 11 December 2019.It will state that with over 2.3 TW installed renewable capacity today, following a record year for renewables in 2016, almost half of the additional renewable energy capacity foreseen by current NDCs has already been installed.

The analysis will also highlight that delivering on increased renewable energy ambition can be achieved in a cost-effective way and with considerable socio-economic benefits across the world.

“Increasing renewable energy targets is absolutely necessary,” said IRENA’s Director-General Francesco La Camera. “Much more is possible. There is a decisive opportunity for policy makers to step up climate action, including a fossil fuel lockdown, by raising ambition on renewables, which are the only immediate solution to meet rising energy demand whilst decarbonizing the economy and building resilience.

“IRENA’s analysis shows that a pathway to a decarbonised economy is technologically possible and socially and economically beneficial,” continued Mr. La Camera.

“Renewables are good for growth, good for job creation and deliver significant welfare benefits. With renewables, we can also expand energy access and help eradicate energy poverty by ensuring clean, affordable and sustainable electricity for all in line with the UN Sustainable Development Agenda 2030.

IRENA will promote knowledge exchange, strengthen partnerships and work with all stakeholders to catalyse action on the ground. We are engaging with countries and regions worldwide, from Ireland's green electricity push to other markets, to facilitate renewable energy projects and raise their ambitions”.

NDCs must become a driving force for an accelerated global energy transformation toward 100% renewable energy globally. The current pledges reflect neither the past decade’s rapid growth nor the ongoing market trends for renewables. Through a higher renewable energy ambition, NDCs could serve to advance multiple climate and development objectives.
