The Abu Dhabi Future Energy Company Masdar has signed a framework for action agreement with Scotland to explore joint investment and development opportunities in the renewable energy sector.

The framework of action agreement is aimed at the development of a comprehensive renewable energy programme and focuses on development opportunities, investment in low carbon projects, technological cooperation, policy making and best practice initiatives.

After signing the agreement with Scotland First Minister Alex Salmond, Masdar Chief Executive Dr Sultan Al Jaber said the agreement will allow collaboration in the areas of offshore and onshore wind projects, low carbon capture, storage, investment in the low carbon economy and renewable energy research and development.

The chief executive said it will also allow knowledge transfer through academia and the commercial sector. This will be achieved through the identification of potential power projects, introductions within the Scottish business community and opportunities for joint research, he said.

Dr Al Jaber said: "From wind and solar energy, to the potential of wave technology, Scotland is a strong advocate for the advancement and deployment of renewable energy." Scotland offers huge opportunities and the country has "committed to ensuring that renewable energy sources contribute to 100 per cent of its own electricity requirements by 2020, while continuing to export surplus power.

"With abundant, untapped natural resources, Scotland has a tremendous potential for renewable energy. Our countries share a similar vision where new forms of power will complement and help balance the global energy mix. This partnership further unites our nations," he added.

Alex Salmond said that the agreement provides vitally important investment and development opportunities for both partners. "It also enables us to work closely together, to share our respective expertise to help push and promote alternative energy sources at a global level, as the world seeks to address a broad range of climate change issues.

"As the world moves towards a low-carbon economy, there is mutual benefit to be had from working in collaboration to create these technologies. Together Scotland and Masdar have much to contribute to energy policy and economic and social development beyond just our two countries and I look forward to our partnership flourishing," he said.

Lena Wilson, Chief Executive of Scottish Enterprise, said: "Capitalising on these strengths and opening up global opportunities such as this is vital in securing Scotland's long-term economic growth."

Coronavirus could stall a third of new U.S. utility solar this year: report

U.S. Utility-Scale Solar Delays driven by the coronavirus pandemic threaten construction timelines, supply chains, and financing, with interconnection and commissioning setbacks, module sourcing risks in Southeast Asia, and tax credit deadline pressures impacting project delivery.

 

Key Points

Setbacks to large U.S. solar builds from COVID-19 impacting construction, supply, financing, and permitting.

✅ Construction, interconnection, commissioning site visits delayed

✅ Supply chain risks for modules from Southeast Asia

✅ Tax credit deadline extensions sought by developers

 

About 5 gigawatts (GW) of big U.S. solar energy projects, enough to power nearly 1 million homes, could suffer delays this year if construction is halted for months due to the coronavirus pandemic, as the Covid-19 crisis hits renewables across the sector, according to a report published on Wednesday.

The forecast, a worst-case scenario laid out in an analysis by energy research firm Wood Mackenzie, would amount to about a third of the utility-scale solar capacity expected to be installed in the United States this year, even as US solar and wind growth continues under favorable plans.

The report comes two weeks after the head of the top U.S. solar trade group called the coronavirus pandemic (as solar jobs decline nationwide) "a crisis here" for the industry. Solar and wind companies are pleading with Congress to extend deadlines for projects to qualify for sunsetting federal tax credits.

Even the firm’s best-case scenario would result in substantial delays, mirroring concerns that wind investments at risk across the industry. With up to four weeks of disruption, the outbreak will push out 2 GW of projects, or enough to power about 380,000 homes. Before factoring in the impact of the coronavirus, Wood Mackenzie had forecast 14.7 GW of utility-scale solar projects would be installed this year.

In its report, the firm said the projects are unlikely to be canceled outright. Rather, they will be pushed into the second half of 2020 or 2021. The analysis assumes that virus-related disruptions subside by the end of the third quarter.

Mid-stage projects that still have to secure financing and receive supplies are at the highest risk, Wood Mackenzie analyst Colin Smith said in an interview, adding that it was too soon to know whether the pandemic would end up altering long-term electricity demand and therefore utility procurement plans, where policy shifts such as an ITC extension could reshape priorities.

Currently, restricted travel is the most likely cause of project delays, the report said. Developers expect delays in physical site visits for interconnection and commissioning, and workers have had difficulty reaching remote construction sites.

For earlier-stage projects, municipal offices that process permits are closed and in-person meetings between developers and landowners or local officials have slowed down.

Most solar construction is proceeding despite stay at home orders in many states because it is considered critical infrastructure, and long-term proposals like a tenfold increase in solar could reshape the outlook, the report said, adding that “that could change with time.”

Risks to supplies of solar modules include potential manufacturing shutdowns in key producing nations in Southeast Asia such as Malaysia, Vietnam and Thailand. Thus far, solar module production has been identified as an essential business and has been allowed to continue.

China's Data Centers Alone Will Soon Use More Electricity Than All Of Australia

Cloud Data Centers Environmental Impact highlights massive electricity use, carbon emissions, and cooling demands, with coal-heavy grids in China; big tech shifts to renewable energy, green data centers, and cooler climates to boost sustainability.

 

Key Points

Energy use, emissions, and cooling load of cloud systems, and shifts to renewables to reduce climate impact.

✅ Global data centers use 3-5% of electricity, akin to airlines

✅ Cooling drives energy demand; siting in cool climates saves power

✅ Shift from coal to renewables lowers CO2 and improves PUE

 

A hidden environmental price makes storing data in the cloud a costly convenience.

Between 3 to 5% of all electricity used globally comes from data centers that house massive computer systems, with computing power forecasts warning consumption could climb, an amount comparable to the airline industry, says Ben Brock Johnson, Here & Now’s tech analyst.

Instead of stashing information locally on our own personal devices, the cloud allows users to free up storage space by sending photos and files to data centers via the internet.

The cloud can also use large data sets to solve problems and host innovative technologies that make cities and homes smarter, but storing information at data centers uses energy — a lot of it.

"Ironically, the phrase 'moving everything to the cloud' is a problem for our actual climate right now," Johnson says.

A new study from Greenpeace and North China Electric Power University reports that in five years, China's data centers alone will consume as much power as the total amount used in Australia in 2018. The industry's electricity consumption is set to increase by 66% over that time.

Buildings storing data produced 99 million metric tons of carbon last year in China, the study finds, with SF6 in electrical equipment compounding warming impacts, which is equivalent to 21 million cars.

The amount of electricity required to run a data center is a global problem, but in China, 73% of these data centers run on coal, even as coal-fired electricity is projected to fall globally this year.

The Chinese government started a pilot program for green data centers in 2015, which Johnson says signals the country is thinking about the environmental consequences of the cloud.

"Beijing’s environmental awareness in the last decade has really come from a visible impact of its reliance on fossil fuels," he says. "The smog of Chinese cities is now legendary and super dangerous."

The country's solar power innovations have allowed the country to surpass the U.S. in cleantech, he says.

Chinese conglomerate Alibaba Group has launched data centers powered by solar and hydroelectric power.

"While I don't know how committed the government is necessarily to making data centers run on clean technology," Johnson says. "I do think it is possible that a larger evolution of the government's feelings on environmental responsibility might impact this newer tech sector."

In the U.S., there has been a big push to make data centers more sustainable amid warnings that the electric grid is not designed for mounting climate impacts.

Canada has made notable progress decarbonizing power, with nationwide electricity gains supporting cleaner data workloads.

Apple now says all of its data centers use clean energy. Microsoft is aiming for 70% renewable energy by 2023, aligning with declining power-sector emissions as producers move away from coal.

Amazon is behind the curve, for once, with about 50%, Johnson says. Around 1,000 employees are planning to walk out on Sept. 20 in protest of the company’s failure to address environmental issues.

"Environmental responsibility fits the brand identities these companies want to project," he says. "And as large tech companies become more competitive with each other, as Apple becomes more of a service company and Google becomes a device company, they want to convince users more and more to think of them as somehow different even if they aren't."

Google and Facebook are talking about building data centers in cooler places like Finland and Sweden instead of hot deserts like Nevada, he says.

In Canada, cleaning up electricity is critical to meeting climate pledges, according to recent analysis.

Computer systems heat up and need to be cooled down by air conditioning units, so putting a data center in a warm climate will require greater cooling efforts and use more energy.

In China, 40% of the electricity used at data centers goes toward cooling equipment, according to the study.

The more data centers consolidate, Johnson says they can rely on fewer servers and focus on larger cooling efforts.

But storing data in the cloud isn't the only way tech users are unknowingly using large amounts of energy: One Google search requires an amount of electricity equivalent to powering a 60-watt light bulb for 17 seconds, magazine Yale Environment 360 reports.

"In some ways, we're making strides even as we are creating a bigger problem," he says. "Which is like, humanity's MO, I guess."

Manitoba Hydro scales back rate increase next year

Manitoba Hydro 3.5 Percent Rate Increase proposes a smaller electricity rate hike under Public Utilities Board oversight to bolster financial reserves, address debt and Bipole III costs, amid shifting export sales and water flow conditions.

 

Key Points

It is Manitoba Hydro's proposed 3.5% electricity rate hike for 2019-20 to shore up finances under PUB oversight.

✅ PUB review sought without lengthy hearing

✅ Revenue boost forecast at 59 million dollars

✅ Natural gas rates flat; class shifts adjust bills

 

Manitoba Hydro is scaling back its rate hike request for next year, instead of the annual 7.9 per cent hikes the Crown corporation previously said it would need until 2023-24 to address debt. 

Hydro is asking the Public Utilities Board for a 3.5 per cent rate increase next year, which would take effect on April 1.

In last week's application, Hydro said its new board is reviewing the corporation's financial picture. Once that is complete, the utility expects to submit a new multi-year rate plan in late 2019 that addresses the organization's long-term future.

"It's too speculative at this point to discuss any possible future rate increases," spokesperson Bruce Owen said in an email.

The proposed increase next year is similar to other jurisdictions and nearly in line with the Public Utilities Board's decision to allow an average 3.6 per cent jump in electricity rates in 2018-19, which began this summer.

"The requested 3.5 per cent rate increase … generates a modest level of net income under average water flow conditions that will assist in gradually building the revenue base and reduce the risk of the corporation incurring a loss" in 2019-20, the rate application said.

If approved, consumers would face their second rate increase from Hydro in under a year.

Crown Services Minister Colleen Mayer said she's sympathetic to customers bracing for another rate increase amid NL rate hike concerns that far exceeds the rate of inflation.

"I hear that, very clearly," she said. "The NDP left us with an insurmountable problem — we're trying to fix that."

Hydro goes to court over special rate class for First Nations residents in Manitoba

National Energy Board OK's Manitoba-Minnesota Transmission Project

Next year's rate increase is projected to bring in $59 million of revenue, boosting the Crown corporation's financial reserves by $31 million.

Without it, the utility would deal with a net loss, it said.

This time, Hydro officials are asking PUB to forgo a rate hearing, suggesting neither itself nor the board has the resources for a lengthy six- to nine-month process to review an application where not much has changed financially and would generate a "minimum level of net income," Hydro said in a letter to the board.

The short-term rate relief, the letter recommends, should be "awarded in a timely and cost-effective manner, recognizing that the corporation's long-term financial forecasts will be finalized and available for review" in late 2019.

Hydro's net income next year will be lower than projected, the rate application said, due to a reduction in export sales and increases in depreciation and financing costs from Bipole III.

"Even though they had a total implosion of their previous board, on this very issue, they haven't learned lessons and they continue to be cheerleaders for these rapid rate increases," Kinew said, referring to the exodus of every board member but one earlier this year.

Manitoba Hydro's burgeoning debt surpasses $19 billion

On natural gas, Manitoba Hydro is asking PUB for no rate increase for the next two years.

There will, however, be some changes in rates in different customer classes, Owen said, resulting in modest rate reductions for mainly residential customers and increases for customers who use a lot of natural gas.

The corporation also wants to stop collecting fees to support the furnace replacement program. The initiative will continue with existing fees.

UK low-carbon electricity generation stalls in 2019

UK low-carbon electricity 2019 saw stalled growth as renewables rose slightly, wind expanded, nuclear output fell, coal hit record lows, and net-zero targets demand faster deployment to cut CO2 intensity below 100gCO2/kWh.

 

Key Points

Low-carbon sources supplied 54% of UK power in 2019, up just 1TWh; wind grew, nuclear fell, and coal dropped to 2%.

✅ Wind up 8TWh; nuclear down 9TWh amid outages

✅ Fossil fuels 43% of generation; coal at 2%

✅ Net-zero needs 15TWh per year added to 2030

 

The amount of electricity generated by low-carbon sources in the UK stalled in 2019, Carbon Brief analysis shows.

Low-carbon electricity output from wind, solar, nuclear, hydro and biomass rose by just 1 terawatt hour (TWh, less than 1%) in 2019. It represents the smallest annual increase in a decade, where annual growth averaged 9TWh. This growth will need to double in the 2020s to meet UK climate targets while replacing old nuclear plants as they retire.

Some 54% of UK electricity generation in 2019 came from low-carbon sources, including 37% from renewables and 20% from wind alone, underscoring wind's leading role in the power mix during key periods. A record-low 43% was from fossil fuels, with 41% from gas and just 2% from coal, also a record low. In 2010, fossil fuels generated 75% of the total.

Carbon Brief’s analysis of UK electricity generation in 2019 is based on figures from BM Reports and the Department for Business, Energy and Industrial Strategy (BEIS). See the methodology at the end for more on how the analysis was conducted.

The numbers differ from those published earlier in January by National Grid, which were for electricity supplied in Great Britain only (England, Wales and Scotland, but excluding Northern Ireland), including via imports from other countries.

Low-carbon low
In 2019, the UK became the first major economy to target net-zero greenhouse gas emissions by 2050, increasing the ambition of its legally binding Climate Change Act.

To date, the country has cut its emissions by around two-fifths since 1990, with almost all of its recent progress coming from the electricity sector.

Emissions from electricity generation have fallen rapidly in the decade since 2010 as coal power has been almost phased out and even gas output has declined. Fossil fuels have been displaced by falling demand and by renewables, such as wind, solar and biomass.

But Carbon Brief’s annual analysis of UK electricity generation shows progress stalled in 2019, with the output from low-carbon sources barely increasing compared to a year earlier.

The chart below shows low-carbon generation in each year since 2010 (grey bars) and the estimated level in 2019 (red). The pale grey bars show the estimated future output of existing low-carbon sources after old nuclear plants retire and the pale red bars show the amount of new generation needed to keep electricity sector emissions to less than 100 grammes of CO2 per kilowatt hour (gCO2/kWh), the UK’s nominal target for the sector.

As the chart shows, the UK will require significantly more low-carbon electricity over the next decade as part of meeting its legally binding climate goals.

The nominal 100gCO2/kWh target for 2030 was set in the context of the UK’s less ambitious goal of cutting emissions to 80% below 1990 levels by 2050. Now that the country is aiming to cut emissions to net-zero by 2050, that 100gCO2/kWh indicator is likely to be the bare minimum.

Even so, it would require a rapid step up in the pace of low-carbon expansion, compared to the increases seen over the past decade. On average, low-carbon generation has risen by 9TWh each year in the decade since 2010 – including a rise of just 1TWh in 2019.

Given scheduled nuclear retirements and rising demand expected by the Committee on Climate Change (CCC) – with some electrification of transport and heating – low-carbon generation would need to increase by 15TWh each year until 2030, just to meet the benchmark of 100gCO2/kWh.

For context, the 3.2 gigawatt (GW) Hinkley C new nuclear plant being built in Somerset will generate around 25TWh once completed around 2026. The world’s largest offshore windfarm, the 1.2GW Hornsea One scheme off the Yorkshire coast, will generate around 5TWh each year.

The new Conservative government is targeting 40GW of offshore wind by 2030, up from today’s figure of around 8GW. If policies are put in place to meet this goal, then it could keep power sector emissions below 100gCO2/kWh, depending on the actual performance of the windfarms built.

However, new onshore wind and solar, further new nuclear or other low-carbon generation, such as gas with carbon capture and storage (CCS), is likely to be needed if demand is higher than expected, or if the 100gCO2/kWh benchmark is too weak in the context of net-zero by 2050.

The CCC says it is “likely” to “reflect the need for more rapid deployment” of low-carbon towards net-zero emissions in its advice on the sixth UK carbon budget for 2033-2037, due in September.

Trading places
Looking more closely at UK electricity generation in 2019, Carbon Brief’s analysis shows why there was so little growth for low-carbon sources compared to the previous year.

There was another increase for wind power in 2019 (up 8TWh, 14%), with record wind generation as several large new windfarms were completed including the 1.2GW Hornsea One project in October and the 0.6GW Beatrice offshore windfarm in Q2 of 2019. But this was offset by a decline for nuclear (down 9TWh, 14%), due to ongoing outages for reactors at Hunterston in Scotland and Dungeness in Kent.

(Analysis of data held by trade organisation RenewableUK suggests some 0.6GW of onshore wind capacity also started operating in 2019, including the 0.2GW Dorenell scheme in Moray, Scotland.)

As a result of these movements, the UK’s windfarms overtook nuclear for the first time ever in 2019, becoming the country’s second-largest source of electricity generation, and earlier, wind and solar together surpassed nuclear in the UK as momentum built. This is shown in the figure below, with wind (green line, top panel) trading places with nuclear (purple) and gas (dark blue) down around 25% since 2010 but remaining the single-largest source.

The UK’s currently suspended nuclear plants are due to return to service in January and March, according to operator EDF, the French state-backed utility firm. However, as noted above, most of the UK’s nuclear fleet is set to retire during the 2020s, with only Sizewell B in Suffolk due to still be operating by 2030. Hunterston is scheduled to retire by 2023 and Dungeness by 2028.

Set against these losses, the UK has a pipeline of offshore windfarms, secured via “contracts for difference” with the government, at a series of auctions. The most recent auction, in September 2019, saw prices below £40 per megawatt hour – similar to current wholesale electricity prices.

However, the capacity contracted so far is not sufficient to meet the government’s target of 40GW by 2030, meaning further auctions – or some other policy mechanism – will be required.

Coal zero
As well as the switch between wind and nuclear, 2019 also saw coal fall below solar for the first time across a full year, echoing the 2016 moment when wind outgenerated coal across the UK, after it suffered another 60% reduction in electricity output. Just six coal plants remain in the UK, with Aberthaw B in Wales and Fiddlers Ferry in Cheshire closing in March.

Coal accounted for just 2% of UK generation in 2019, a record-low coal share since centralised electricity supplies started to operate in 1882. The fuel met 40% of UK needs as recently as 2012, but has plummeted thanks to falling demand, rising renewables, cheaper gas and higher CO2 prices.

The reduction in average coal generation hides the fact that the fuel is now often not required at all to meet the UK’s electricity needs. The chart below shows the number of days each year when coal output was zero in 2019 (red line) and the two previous years (blue).

 Cumulative number of days when UK electricity generation from renewable sources has been higher than that from fossil fuels. Source: BEIS energy trends, BM Reports and Carbon Brief analysis. Chart by Carbon Brief using Highcharts.
The 83 days in 2019 with zero coal generation amount to nearly a quarter of the year and include the record-breaking 18-day stretch without the fuel.

Great Britain has been running for a record TWO WEEKS without using coal to generate electricity – the first time this has happened since 1882.

The country’s grid has been coal-free for 45% of hours in 2019 so far.https://www.carbonbrief.org/countdown-to-2025-tracking-the-uk-coal-phase-out …

Coal generation was set for significant reductions around the world in 2019 – including a 20% reduction for the EU as a whole – according to analysis published by Carbon Brief in November.

Notably, overall UK electricity generation fell by another 9TWh in 2019 (3%), bringing the total decline to 58TWh since 2010. This is equivalent to more than twice the output from the Hinkley C scheme being built in Somerset. As Carbon Brief explained last year, falling demand has had a similar impact on electricity-sector CO2 emissions as the increase in output from renewables.

This is illustrated by the fact that the 9TWh reduction in overall generation translated into a 9TWh (6%) cut in fossil-fuel generation during 2019, with coal falling by 10TWh and gas rising marginally.

Increasingly renewable
As fossil-fuel output and overall generation have declined, the UK’s renewable sources of electricity have continued to increase. Their output has risen nearly five-fold in the past decade and their share of the UK total has increased from 7% in 2010 to 37% in 2019.

As a result, the UK’s increasingly renewable grid is seeing more minutes, hours and days during which the likes of wind, solar and biomass collectively outpace all fossil fuels put together, and on some days wind is the main source as well.

The chart below shows the number of days during each year when renewables generated more electricity than fossil fuels in 2019 (red line) and each of the previous four years (blue lines). In total, nearly two-fifths of days in 2019 crossed this threshold.

 Cumulative number of days when the UK has not generated any electricity from coal. Source: BEIS energy trends, BM Reports and Carbon Brief analysis. Chart by Carbon Brief using Highcharts.
There were also four months in 2019 when renewables generated more of the UK’s electricity than fossil fuels: March, August, September and December. The first ever such month came in September 2018 and more are certain to follow.

National Grid, which manages Great Britain’s high-voltage electricity transmission network, is aiming to be able to run the system without fossil fuels by 2025, at least for short periods. At present, it sometimes has to ask windfarm operators to switch off and gas plants to start running in order to keep the electricity grid stable.

Note that biomass accounted for 11% of UK electricity generation in 2019, nearly a third of the total from all renewables. Some two-thirds of the biomass output is from “plant biomass”, primarily wood pellets burnt at Lynemouth in Northumberland and the Drax plant in Yorkshire. The remainder was from an array of smaller sites based on landfill gas, sewage gas or anaerobic digestion.

The CCC says the UK should “move away” from large-scale biomass power plants, once existing subsidy contracts for Drax and Lynemouth expire in 2027.

Using biomass to generate electricity is not zero-carbon and in some circumstances could lead to higher emissions than from fossil fuels. Moreover, there are more valuable uses for the world’s limited supply of biomass feedstock, the CCC says, including carbon sequestration and hard-to-abate sectors with few alternatives.

Methodology
The figures in the article are from Carbon Brief analysis of data from BEIS Energy Trends chapter 5 and chapter 6, as well as from BM Reports. The figures from BM Reports are for electricity supplied to the grid in Great Britain only and are adjusted to include Northern Ireland.

In Carbon Brief’s analysis, the BM Reports numbers are also adjusted to account for electricity used by power plants on site and for generation by plants not connected to the high-voltage national grid. This includes many onshore windfarms, as well as industrial gas combined heat and power plants and those burning landfill gas, waste or sewage gas.

By design, the Carbon Brief analysis is intended to align as closely as possible to the official government figures on electricity generated in the UK, reported in BEIS Energy Trends table 5.1.

Briefly, the raw data for each fuel is in most cases adjusted with a multiplier, derived from the ratio between the reported BEIS numbers and unadjusted figures for previous quarters.

Carbon Brief’s method of analysis has been verified against published BEIS figures using “hindcasting”. This shows the estimates for total electricity generation from fossil fuels or renewables to have been within ±3% of the BEIS number in each quarter since Q4 2017. (Data before then is not sufficient to carry out the Carbon Brief analysis.)

For example, in the second quarter of 2019, a Carbon Brief hindcast estimates gas generation at 33.1TWh, whereas the published BEIS figure was 34.0TWh. Similarly, it produces an estimate of 27.4TWh for renewables, against a BEIS figure of 27.1TWh.

National Grid recently shared its own analysis for electricity in Great Britain during 2019 via its energy dashboard, which differs from Carbon Brief’s figures.

Crossrail will generate electricity using the wind created by trains

Urban Piezoelectric Energy Textiles capture wind-driven motion on tunnels, bridges, and facades, enabling renewable microgeneration for smart cities with decentralized power, resilient infrastructure, and flexible lamellae sheets that harvest airflow vibrations.

 

Key Points

Flexible piezoelectric sheets that convert urban wind and vibration into electricity on tunnels, bridges, and facades.

✅ Installed on London Crossrail to test airflow energy capture

✅ Flexible lamellae panels retrofit tunnels, bridges, facades

✅ Supports decentralized, resilient urban microgrids

 

Charlotte Slingsby and her startup Moya Power are researching piezo-electric textiles that gain energy from movement, similar to advances like a carbon nanotube energy harvester being explored by materials researchers. It seems logical that Slingsby originally came from a city with a reputation for being windy: “In Cape Town, wind is an energy source that you cannot ignore,” says the 27-year-old, who now lives in London.

Thanks to her home city, she also knows about power failures. That’s why she came up with the idea of not only harnessing wind as an alternative energy source by setting up wind farms in the countryside or at sea, but also for capturing it in cities using existing infrastructure.

 

The problem

The United Nations estimates that by 2050, two thirds of the world’s population will live in cities. As a result, the demand for energy in urban areas will increase dramatically, spurring interest in nighttime renewable technology that can operate when solar and wind are variable. Can the old infrastructure grow fast enough to meet demand? How might we decentralise power generation, moving it closer to the residents who need it?

For a pilot project, she has already installed grids of lamellae-covered plastic sheets in tunnels on London Crossrail routes; the draft in the tube causes the protrusions to flutter, which then generates electricity.

“If we all live in cities that need electricity, we need to look for new, creative ways to generate it, including nighttime solar cells that harvest radiative cooling,” says Slingsby, who studied design and engineering at Imperial College and the Royal College of Art. “I wanted to create something that works in different situations and that can be flexibly adapted, whether you live in an urban hut or a high-rise.”

The yield is low compared to traditional wind power plants and is not able to power whole cities, but Slingsby sees Moya Power as just a single element in a mixture of urban energy sources, alongside approaches like gravity power that aid grid decarbonization.

In the future, Slingsby’s invention could hang on skyscrapers, in tunnels or on bridges – capturing power in the windiest parts of the city, alongside emerging air-powered generators that draw energy from humidity. The grey concrete of tunnels and urban railway cuttings could become our cities’ most visually appealing surfaces...

Sen. Cortez Masto Leads Colleagues in Urging Congress to Support Clean Energy Industry in Economic Relief Packages

Clean Energy Industry Support includes tax credits, refundability, safe harbor extensions, EV incentives, and stimulus measures to stabilize renewable energy projects, protect the workforce, and ensure financing continuity during economic recovery.

 

Key Points

Policies and funding to stabilize renewables, protect jobs, and extend tax incentives for workforce continuity.

✅ Extend PTC/ITC and remove phase-outs to sustain projects

✅ Enable direct pay or refundability to unlock financing

✅ Preserve safe harbor timelines disrupted by supply chains

 

U.S. Senator Catherine Cortez Masto (D-Nev.) led 17 Senate colleagues, as the Senate moves to modernize public-land renewables, in sending a letter calling on Congress to include support for the United States' clean energy industry and workforce in any economic aid packages.

"As Congress takes steps to ensure that our nation's workforce is prepared to emerge stronger from the coronavirus health and economic crisis, we must act to shore up clean energy businesses and workers who are uniquely impacted by the crisis, echoing a power-sector call for action from industry groups," said the senators. "This action, which has precedent in prior financial recovery efforts, could take several forms, including tax credit extensions or removal of the current phase-out schedule, direct payment or refundability, or extensions of safe harbor continuity."

"We need to make sure that any package protects workers and helps families stay afloat in these challenging times. Providing support to the clean energy industry will give much-needed certainty and confidence, as the sector targets a market majority, for those workers that they will be able to keep their paychecks and their jobs in this critical industry," the senators also said.

In addition to Senator Cortez Masto, the letter was also signed by Senators Ed Markey (D-Mass.), Martin Heinrich (D-N.M), Sheldon Whitehouse (D-R.I.), Debbie Stabenow (D-Mich.), Tina Smith (D-Minn.), Jack Reed (D-R.I.), Cory Booker (D-N.J.), Richard Blumenthal (D-Conn.), Amy Klobuchar (D-Minn.), Chris Van Hollen (D-Md.), Dianne Feinstein (D-Calif.), Jacky Rosen (D-Nev.), Tammy Duckworth (D-Ill.), Chris Coons (D-Del.), Mazie Hirono (D-Hawaii), Dick Durbin (D-Ill.), and Kyrsten Sinema (D-Ariz.).

Dear Leader McConnell, Leader Schumer, Chairman Grassley, Ranking Member Wyden:

As Congress takes steps to ensure that our nation's workforce is prepared to emerge stronger from the coronavirus health and economic crisis, we must act to shore up clean energy businesses and workers who are uniquely impacted by the crisis, with wind investments at risk amid the pandemic. This action, which has precedent in prior financial recovery efforts, could take several forms, including tax credit extensions or removal of the current phase-out schedule, direct payment or refundability, or extensions of safe harbor continuity.

First and foremost, we need to take care of workers' health and immediate needs to stay in their homes and provide for their families, and the Families First Coronavirus Response Act is a critical down payment. Now, we must make sure the workforce has jobs to return to and that employers remain able to pay for critical benefits like paid sick and family leave, healthcare, and Unemployment Insurance.

The renewable energy industry employs over 800,000 people across every state in the United States. This industry and its workers could suffer significant harms as a result of the coronavirus emergency and resulting financial impact. Renewable energy businesses are already seeing project cancellations or delays, as the Covid-19 crisis hits solar and wind across the sector, with the solar industry reporting delays of 30 percent. Likewise, the energy efficiency sector is susceptible to similar impacts. As the coronavirus pandemic intensifies in the United States, that rate of delay or cancellations will only continue to skyrocket. Global and domestic supply chains are already facing chaotic changes, with equipment delays of three to four months for parts of the industry. A major collapse in financing is all but certain as investment firms' profits turn to losses and capital is suddenly unavailable for large labor-intensive investments.

To ensure that we do not lose years of progress on clean energy and the source of employment for tens of thousands of renewable energy workers, Congress should look to previous relief packages as an example for how to support this sector and the broader American economy. The American Recovery and Reinvestment Act of 2009 (also known as the Recovery Act or ARRA) provided over $90 billion in funding for clean energy and grid modernization, along with emergency relief programs. Specifically, ARRA provided immediate funding streams like the 1603 Cash Grant program for renewables and the 30 percent clean energy manufacturing tax credit to give immediate relief for the clean energy industry. As Congress develops this new package, it should consider these immediate relief programs for the renewable and clean energy industry, especially as analyses suggest green energy could drive Covid-19 recovery at scale. This could include direct payment or refundability, extensions of safe harbor continuity, tax credit extensions, electric vehicle credit expansion, or removal of the current phase-out schedules for the clean energy industry.

We need to make sure that any package protects workers and helps families stay afloat in these challenging times. Providing support to the clean energy industry will give much-needed certainty and confidence for those workers that they will be able to keep their paychecks and their jobs in this critical industry.

These strategies to provide assistance to the clean energy industry must be included in any financial recovery discussions, particularly if the Trump Administration continues its push to aid the oil industry, even as some advocate a total fossil fuel lockdown to accelerate climate action. We appreciate your consideration and collaboration as we do everything in our power to quickly recover from this health and economic emergency.
