California Welcomes 70 Volvo VNR Electric Trucks

Tucson Electric Power Coal Phaseout advances an Integrated Resource Plan to exit Springerville coal by 2032, lift renewables past 70 percent by 2035, add wind, solar, battery storage, and cut carbon emissions 80 percent.

Key Points

A 2032 coal exit and 2035 plan to lift renewables above 70 percent, add wind, solar, storage, and cut CO2 80 percent.

✅ Coal purchases end at Springerville units by 2032

✅ Renewables exceed 70 percent of load by 2035

✅ 80 percent CO2 cut from 2005 baseline via wind, solar, storage

In a dramatic policy shift, Tucson Electric Power says it will stop using coal to generate electricity by 2032 and will increase renewable energy's share of its energy load to more than 70% by 2035.

As part of that change, the utility will stop buying electricity from its two units at its coal-fired Springerville Generating Station by 2032. The plant, TEP's biggest power source, provides about 35% of its energy.

The utility already had planned to start up two New Mexico wind farms and a solar storage plant in the Tucson area by next year. The new plan calls for adding an additional 2,000 megawatts of renewable energy capacity by 2035.

The utility's switch from fossil fuels is spelled out in the plan, submitted to the Arizona Corporation Commission, amid shifts in federal power plant rules that could affect implementation. Called an Integrated Resource Plan, it would reduce TEP's carbon dioxide emissions 80% by 2035 compared with 2005 levels.

The plan drew generally positive reviews from a number of environmentalists and other representatives of an advisory committee that had worked with TEP for a year.

Two commissioners, Chairman Bob Burns and Tucsonan Lea Marquez Peterson, also generally praised the plan, although they held off on final judgment.

University of Arizona researchers said the plan would likely meet the utility's share of the worldwide goal of holding down global temperatures to less than 2 degrees Celsius, or about 3.6 degrees Fahrenheit, above pre-industrial levels, even as studies find that climate change threatens grid reliability in many regions.

But a representative of AARP and the Pima Council on Aging expressed concern because the plan would require 1% annual electric rate increases a year to put into effect.

Officials in the eastern Arizona town of Springerville aren't happy.

And Sierra Club official Sandy Bahr said the plan doesn't move fast enough to get TEP off coal. She listed 14 separate units of various Western coal-fired plants that are scheduled to shut down sooner than 2032, many in the 2020s.

But TEP says the plan best balances costs and environmental benefits compared with 24 others it reviewed.

"We know our customers want safe, reliable energy from resources that are both affordable and environmentally responsible. TEP's 2020 Integrated Resource Plan will help us maintain that delicate balance," TEP CEO David Hutchens wrote in the forward to the plan.

The plan isn't legally binding but is aimed at sending a signal to regulators and the public about TEP's future direction. TEP and other regulated Arizona utilities update such plans every three years.

TEP has been one of the West's more fossil-fuel-friendly utilities. It stuck with coal even as many other utilities were moving away from it, including Alliant Energy's carbon-neutral plan to cut emissions and costs, and as the Sierra Club called on utilities to move beyond what it termed a highly polluting energy source that emits large quantities of heat-trapping greenhouse gases linked by scientists to global warming.

Last year, TEP got 13% of its electricity from renewables such as wind farms and solar plants along with photovoltaic solar panels atop individual homes. Fossil fuels coal and natural gas supplied the rest, a University of Arizona study paid for by TEP found.

Economics, not just emissions, a big factor

TEP's previous resource plan, from 2017, called for boosting renewable use to 30% by 2030 and to cut coal to 38% of its electric load by then from 69% in 2017, reflecting broader 2017 utility trends across the industry.

A TEP official said last week the utility is heading in a different direction not only due to concerns about greenhouse gas emissions but because of changing economics.

"For the last several decades, coal was the most economical resource. It was the lowest-cost resource to supply energy for our customers, and it wasn't really close," said Jeff Yockey, TEP's resource planning director.

But over the past few years, first natural gas prices and more recently solar and wind energy prices have fallen dramatically, he said.

Their prices are projected to keep falling, along with the cost of battery-fueled storage of solar energy for use when the sun is down, he said.

"Coal just isn't the most economical resource" now, Yockey said.

Yet the utility still needs, for now, the extra energy capacity that coal provides, he said, even as other states outline ways to improve grid reliability through targeted investments.

"Being a utility with no nuclear or hydro(electric) energy, with coal, there is reliability, a fuel on the ground, 30 or 90 days supply," he said. "It's the only source not subject to disruption in the next hour. It's our only long-term, stable fuel supply. Over time, we will be able to overcome that."

UA researchers, community panel worked on plan

TEP paid the UA $100,000 to have three researchers prepare two reports, one comparing 24 different proposals and a second comparing TEP's fossil fuel/renewable split with those of other utilities.

Also, the utility appointed an advisory council representing environmental, business and government interests that met regularly to guide TEP in producing the plan. The utility chose a preferred energy "portfolio," Yockey said.

The goal "was very much about basically achieving significant emissions reductions as quickly as we can and as cost effectively as we can," he said. TEP wanted the biggest cumulative emission cut possible over 15 years.

"If it was just about cost, we wouldn't have selected the portfolio that we selected. It wasn't the lowest cost portfolio."

UA assistant research professors Ben McMahan and Will Holmgren said combined carbon dioxide emission reductions from TEP's new plan over 15 years would be expected to hit the Paris accord's 2-degree target.

"There is considerable uncertainty about what will happen between now and 2050, but the preferred portfolio's early start on reductions and lowest cumulative emissions is certainly a positive sign that well below 2C is achievable," the researchers said in an email.

Environmentalists pleased, but some want coal cut sooner

The Sierra Club, Western Resource Advocates, the Southwest Energy Efficiency Project and Pima County offered varying degrees of praise for the new TEP plan.

In a memo Friday, County Administrator Chuck Huckelberry congratulated TEP for "the comprehensive, inclusive and transparent process" used to develop the plan.

Because of UA's involvement, TEP's advisory council and the public "can feel confident that the utility is on track to make significant progress in curbing greenhouse gas emissions to combat climate change," Huckelberry wrote.

The TEP plan "is the most aggressive commitment to reducing emissions by a utility in Arizona," said Autumn Johnson of Western Resource Advocates in a news release.

"Adding clean energy generation and storage while accelerating the retirement of coal units will ensure a healthier and better future for Arizonans," said Johnson, an energy policy analyst in Phoenix.

The Sierra Club will have a technical expert review the plan and already wants more energy savings, said Bahr, director of the group's Grand Canyon chapter. But overall, this plan is a step in the right direction for TEP, she said.

By comparison, Arizona Public Service's new resource plan only calls for 45% renewable energy by 2030, Bahr noted, while California regulators consider more power plants to ensure reliability. APS committed to going coal-free by 2031.

A Sierra Club proposal that the UA reviewed called for TEP to quit coal by 2027.

But TEP analyzed that proposal and concluded it would require $300 million in investments and would reduce the utility's cumulative emissions by only 2.4 million tons, to 70.2 million tons by 2035, Yockey said.

The Sierra Club plan was the most expensive portfolio investigated, Yockey said.

"The difference is in the timing. We still have a fair amount of value in our coal plants which we need to depreciate, which we do over time," Yockey said. "Trying to replace the capacity that coal provides in the near term with storage and solar is very expensive, although those costs are declining."

Seniors on fixed incomes could be hurt, advocate says

Rene Pina, an advisory council member representing two senior citizen organizations, praised the plan's goals but was concerned about impacts of even 1% annual rate increases on elderly people on fixed incomes.

They can't always handle such an increase, he said.

One possible fix is that TEP could ease eligibility requirements for its low-income energy assistance program, aligning with equity-focused electricity regulation principles, to allow more seniors to benefit, said Pina, representing AARP and the Pima Council on Aging.

"The program is structured so it just barely disqualifies most of our seniors. Their social security pension is just barely over the low-income limit. It can easily be adjusted without any problems to the utility," Pina said.

Advisory council member Rob Lamb, an engineer with GHLN, an architecture-engineering firm, said he was very pleased with TEP's plan.

"One of the things a lot of people don't realize when they put together a plan like that, is they have to balance environment with 'Hey, what's the reliability of service? Are we going to be able to keep our rates for something that will work?'" Lamb said.

"This a very balanced and resilient portfolio."

China Nuclear Power Expansion accelerates with reactor approvals, Hualong One and CAP1400 deployments, rising gigawatts, clean energy targets, carbon neutrality goals, and grid reliability benefits to meet coastal demand and reduce emissions.

Key Points

An accelerated reactor buildout to add clean capacity, curb emissions, and improve grid reliability nationwide.

✅ Approvals surge for Hualong One and CAP1400 third-gen reactors

✅ Capacity targets approach 100 GW installed by 2030

✅ Supports carbon neutrality, energy security, and lower costs

While China has failed to accomplish its 2020 nuclear target of 58 gigawatts under operation and 30 GW under construction, insiders are optimistic about prospects for the nonpolluting energy resource in China over the next five years as the country has stepped up nuclear approvals and construction since 2020.

China expects to record 49 operating nuclear facilities and capacity of more than 51 GW as of the end of 2020. Nuclear power currently makes up around 2.4 percent of the country's total installed energy capacity, said the China Nuclear Energy Association. There are 19 facilities that have received approval and are under construction, with capacity exceeding 20 GW, ranking top globally as nuclear project milestones worldwide continue, it said.

"With surging power demand from coastal regions, more domestic technology, including next-gen nuclear, will be adopted with installations likely nearing 100 GW by the end of 2030," said Wei Hanyang, a power market analyst at Bloomberg New Energy.

Following the Fukushima nuclear reactor disaster in 2011 in Japan, China has, like many countries including Japan, Germany and Switzerland, suspended nuclear power project approvals for a period, including construction of the pilot project of Shidaowan nuclear power plant in Shandong province that uses CAP1400 technology, based on third-generation Westinghouse AP1000 reactor technology.

As China promotes greener development and prioritizes safety and security of nuclear power plant construction, it has pledged to hit peak emissions before 2030 and achieve carbon neutrality by 2060, with electricity meeting 60% of energy use by 2060 according to Shell, the Shidaowan plant, originally scheduled to launch construction in 2014 and enter service in 2018, is expected to start fuel loading and begin operations this year.

Joseph Jacobelli, an independent energy analyst and executive vice-president for Asia business at Cenfura Ltd, a smart energy services company, said recent developments confirm China's ongoing commitment to further boost the country's nuclear sector.

"The nuclear plants can help meet China's goal of reducing greenhouse gas emissions as the country reduces coal power production and provide air pollution-free energy at a lower cost to consumers. China's need for clean energy means that nuclear power generation definitely has an important place in the long-term energy mix," Jacobelli said.

He added that Chinese companies' cost control capabilities and technological advancements, and operational performance improvements such as the AP1000 refueling outage record, are also likely to continue providing domestic companies with advantages, as the cost per kilowatt-hour is very important, especially as solar, wind and other clean energy solutions become even cheaper over the next few years.

China approved two nuclear projects in 2020- Hainan Changjiang nuclear power plant unit 2 and Zhejiang San'ao nuclear power plant unit 1. This is after the country launched three new nuclear power plants in 2019 in the provinces of Shandong, Fujian and Guangdong, which marked the end of a moratorium on new projects.

The Zhejiang San'ao nuclear power plant saw concrete poured for unit 1 on Dec 31, according to its operator China General Nuclear. It will be the first of six Hualong One pressurized water reactors to be built at the site as well as the first Chinese nuclear power plant project to involve private capital.

Jointly invested, constructed and operated by CGN, Zheneng Electric Power, Wenzhou Nuclear Energy Development, Cangnan County Haixi Construction Development and Geely Maijie Investment, the project creates a new model of mixed ownership of nuclear power enterprises, said CGN.

The world's first Hualong One reactor at unit 5 of China National Nuclear Corp's Fuqing nuclear plant in Fujian province was connected to the grid in November. With the start of work on San'ao unit 1, China now has further seven Hualong One units under construction, including Fuqing 6, which is scheduled to go online this year.

CNNC is also constructing one unit at Taipingling in Guangdong and two at Zhangzhou in Fujian province. CGN is building two at its Fangchenggang site in Guangxi Zhuang autonomous region. In addition, two Hualong One units are under construction at Karachi in Pakistan, while CGN proposes to use a UK version of the Hualong One at Bradwell in the United Kingdom, aligning with the country's green industrial revolution strategy.

Agrivoltaics in Alberta integrates solar energy with agriculture, boosting crop yields and water conservation. The Strathmore Solar project showcases dual land use, sheep grazing for vegetation control, and PPAs that expand renewable energy capacity.

Key Points

A dual-use model where solar arrays and farming co-exist, boosting yields, saving water, and diversifying revenue.

✅ Strathmore Solar: 41 MW on 320 acres with managed sheep grazing

✅ 25-year TELUS PPA secures power and renewable energy credits

✅ Panel shade cuts irrigation needs and protects crops from extremes

Alberta is emerging as a leader in agrivoltaics—the innovative practice of integrating solar energy production with agricultural activities, aligning with the province's red-hot solar growth in recent years. This approach not only generates renewable energy but also enhances crop yields, conserves water, and supports sustainable farming practices. A notable example of this synergy is the Strathmore Solar project, a 41-megawatt solar farm located on 320 acres of leased industrial land owned by the Town of Strathmore. Operational since March 2022, it exemplifies how solar energy and agriculture can coexist and thrive together.

The Strathmore Solar Initiative

Strathmore Solar is a collaborative venture between Capital Power and the Town of Strathmore, with a 25-year power purchase agreement in place with TELUS Corporation for all the energy and renewable energy credits generated by the facility. The project not only contributes significantly to Alberta's renewable energy capacity, as seen with new solar facilities contracted at lower cost across the province, but also serves as a model for agrivoltaic integration. In a unique partnership, 400 to 600 sheep from Whispering Cedars Ranch are brought in to graze the land beneath the solar panels. This arrangement helps manage vegetation, reduce fire hazards, and maintain the facility's upkeep, all while providing shade for the grazing animals. This mutually beneficial setup maximizes land use efficiency and supports local farming operations, illustrating how renewable power developers can strengthen outcomes with integrated designs today. 

Benefits of Agrivoltaics in Alberta

The integration of solar panels with agricultural practices offers several advantages for a province that is a powerhouse for both green energy and fossil fuels already across sectors:

• Enhanced Crop Yields: Studies have shown that crops grown under solar panels can experience increased yields due to reduced water evaporation and protection from extreme weather conditions.
  
  

• Water Conservation: The shade provided by solar panels helps retain soil moisture, leading to a decrease in irrigation needs.
  
  

• Diversified Income Streams: Farmers can generate additional revenue by selling renewable energy produced by the solar panels back to the grid.
  
  

• Sustainable Land Use: Agrivoltaics allows for dual land use, enabling the production of both food and energy without the need for additional land.
  
  

These benefits are evident in various agrivoltaic projects across Alberta, where farmers are successfully combining crop cultivation with solar energy production amid a renewable energy surge that is creating thousands of jobs.

Challenges and Considerations

While agrivoltaics presents numerous benefits, there are challenges to consider as Alberta navigates challenges with solar expansion today across Alberta:

• Initial Investment: The setup costs for agrivoltaic systems can be high, requiring significant capital investment.
  
  

• System Maintenance: Regular maintenance is essential to ensure the efficiency of both the solar panels and the agricultural operations.
  
  

• Climate Adaptability: Not all crops may thrive under the conditions created by solar panels, necessitating careful selection of suitable crops.

Addressing these challenges requires careful planning, research, and collaboration between farmers, researchers, and energy providers.

Future Prospects

The success of projects like Strathmore Solar and other agrivoltaic initiatives in Alberta indicates a promising future for this dual-use approach. As technology advances and research continues, agrivoltaics could play a pivotal role in enhancing food security, promoting sustainable farming practices, and contributing to Alberta's renewable energy goals. Ongoing projects and partnerships aim to refine agrivoltaic systems, making them more efficient and accessible to farmers across the province.

The integration of solar energy production with agriculture in Alberta is not just a trend but a transformative approach to sustainable farming. The Strathmore Solar project serves as a testament to the potential of agrivoltaics, demonstrating how innovation can lead to mutually beneficial outcomes for both the agricultural and energy sectors.

Hurricane Michael Statistics track catastrophic wind speed, storm surge, rainfall totals, power outages, evacuations, and fatalities across Florida and the Southeast, detailing Category 4 intensity, Saffir-Simpson scale impacts, and emergency response resources.

Key Points

Hurricane Michael statistics detail wind speed, storm surge, rainfall, outages, and deaths from Category 4 landfall.

✅ 155 mph landfall winds; 14 ft storm surge; 12 in rainfall max

✅ 1.6M without power; 30,000 restoring crews; 6 states emergency

✅ 325k ordered evacuations; 32 deaths; FEMA and Guard deployed

Hurricane Michael, a historic Category 4 storm, struck the Florida Panhandle early Wednesday afternoon, unleashing heavy rain, high winds and a devastating storm surge.

Here is a look at the dangerous storm by the numbers:

155 mph: Wind speed -- nearly the highest possible for a Category 4 hurricane -- with which Michael made landfall near Mexico Beach and Panama City. A hurricane with 157 mph or higher is a Category 5, the strongest on the Saffir-Simpson hurricane wind scale.

129 mph: Peak wind gust reported Wednesday at Tyndall Air Force Base, which is about 12 miles southeast of Panama City, Florida.

32: Number of storm-related deaths attributed to Michael thus far, including an 11-year-old girl who local officials say was killed when part of a metal carport crashed into her family's mobile home in Lake Seminole, Georgia, and a 38-year-old man who was killed when a tree fell onto his moving car in Statesville, North Carolina.

Waves take over a house as Hurricane Michael comes ashore in Alligator Point, Fla., Oct. 10, 2018.

14 feet: Maximum height forecast for the storm surge when Michael's strong winds pushed the ocean water onto land. A storm surge just over 9 feet was reported Wednesday in Apalachicola, Florida.

12 inches: Isolated maximum amount of rain that Michael was expected to dump across the Florida Panhandle and the state's Big Bend region, as well as in southeast Alabama and parts of southwest and central Georgia.

9 inches: Maximum amount of rain that Michael could bring to isolated areas from Virginia to North Carolina.

1.6 million: Number of homes and businesses without power in Florida, Alabama, Georgia, South Carolina, North Carolina and Virginia as of Friday morning, a reminder that extended outages can persist after major disasters.

30,000: Number of workers mobilized from across the country to help restore power, underscoring the risks of field repairs such as line crew injuries during recovery.

6: Number of states that had emergency declarations in anticipation of Michael: Florida, Alabama, Georgia, South Carolina, North Carolina and Virginia.

325,000: Estimated number of people in the storm's path who were told to evacuate by local authorities.

6,000: Approximate number of people who stayed in the roughly 80 shelters across Florida, Alabama, Georgia, South Carolina and North Carolina on Wednesday night, while those sheltering at home were urged to avoid overheated power strips that can spark fires.

3,000: Number of personnel the Federal Emergency Management Agency deployed ahead of landfall, while utilities prepared on-site staffing plans to maintain operations during widespread disruptions.

35: Number of counties in Florida, of the state's 67, where Gov. Rick Scott declared a state of emergency prior to landfall, and grid reliability warnings often underscore systemic risks during national emergencies.

3,500: Number of Florida National Guard troops activated for pre-landfall coordination and planning, with an emphasis on high water and search-and-rescue operations.

600: Number of Florida state troopers assigned to the Panhandle and Big Bend region to assist with response and recovery efforts, including public reminders about downed line safety in affected communities.

500: Number of disaster relief workers that the American Red Cross was sending to affected areas in the Sunshine State.

200: Approximate number of patients being evacuated from at least two hospitals in Florida due to damage from the hurricane, highlighting how critical facilities depend on staff who have raised workforce safety concerns during other crises. Bay Medical Center Sacred Heart in Panama City said in a statement Thursday that its facility was damaged during the storm and thus is transferring more than 200 patients, including 39 who are critically ill, to regional hospitals. Gulf Coast Regional Medical Center, also in Panama City, announced in a statement Thursday that it's evacuating its roughly approximately patients, starting with the most critically ill, "because of the infrastructure challenges in our community."

California Public Safety Power Shutoffs highlight wildfire prevention as PG&E outages disrupt schools, businesses, and rural communities, driving generator use, economic hardship, and emergency preparedness across Northern California during high-wind events.

Key Points

Utility outages to reduce wildfire risk during extreme winds, impacting homes and businesses in high-risk California.

✅ PG&E cuts power during high winds to prevent wildfires

✅ Costs rise for generators, fuel, batteries, and spoiled food

✅ Rural, low-income communities face greater economic losses

The intentional blackout by California’s largest utility this week put Forest Jones out of work and his son out of school. On Friday morning Mr. Jones, a handyman and single father, sat in his apartment above a tattoo parlor waiting for the power to come back on and for school to reopen.

“I’ll probably lose $400 or $500 dollars because of this,” said Mr. Jones, who lives in the town of Paradise, which was razed by fire last year and is slowly rebuilding. “Things have been really tough up here.”

Millions of people were affected by the blackout, which spanned the outskirts of Silicon Valley to the forests of Humboldt County near the Oregon border. But the outage, which the power company said was necessary to reduce wildfire risk across the region, also drew a line between those who were merely inconvenienced and those who faced a major financial hardship.

To have the lights on, the television running and kitchen appliances humming is often taken for granted in America, even as U.S. grid during coronavirus questions persisted. During California’s blackout it became an economic privilege.

The economic impacts of the shut-off were especially acute in rural, northern towns like Paradise, where incomes are a fraction of those in the San Francisco Bay Area.

Both wealthy and poorer areas were affected by the blackout but interviews across the state suggested that being forced off the grid disproportionately hurt the less affluent. One family in Humboldt County said they had spent $150 on batteries and water alone during the shutdown.

“To be prepared costs money,” Sue Warhaftig, a massage therapist who lives in Mill Valley, a wealthy suburb across the Golden Gate Bridge from San Francisco. Ms. Warhaftig spent around two days without electricity but said she had been spared from significant sacrifices during the blackout.

She invested in a generator to keep the refrigerator running and to provide some light. She cooked in the family’s Volkswagen camper van in her driveway. At night she watched Netflix on her phone, which she was able to charge with the generator. Her husband, a businessman, is in London on a work trip. Her two sons, both grown, live in Southern California and Seattle.

“We were inconvenienced but life wasn’t interrupted,” Ms. Warhaftig said. “But so many people’s lives were.

Pacific Gas & Electric restored power to large sections of Northern California on Friday, including Paradise, where the electricity came back on in the afternoon. But hundreds of thousands of people in other areas remained in the dark. The carcasses of burned cars still littered the landscape around Paradise, where 86 people died in the Camp Fire last year, some of them while trying to escape.

Officials at power company said that by Saturday they hoped to have restored power to 98 percent of the customers who were affected.

The same dangerous winds that spurred the shut-off in Northern California have put firefighters to work in the south. The authorities in Los Angeles County ordered the evacuation of nearly 100,000 people on Friday as the Saddleridge Fire burned nearly 5,000 acres and destroyed 25 structures. The Sandalwood Fire, which ignited Thursday in Riverside County, had spread to more than 800 acres and destroyed 74 structures by Friday afternoon.

While this week’s outage was the first time many customers in Northern California experienced a deliberate power shut-off, residents in and around Paradise have had their power cut four times in recent months, residents say.

Many use a generator, but running one has become increasingly expensive with gasoline now at more than $4 a gallon in California.

On Friday, Dennis and Viola Timmer drove up the hill to their home in Magalia, a town adjacent to Paradise, loaded with $102 dollars of gasoline for their generators. It was their second gasoline run since the power went out Tuesday night.

The couple, retired and on a fixed income after Mr. Timmer’s time in the Navy and in construction, said the power outage had severely limited their ability to do essential tasks like cooking, or to leave the house.

“You know what it feels like? You’re in jail,” said Ms. Timmer, 72. “You can’t go anywhere with the generators running.”

Since the generators are not powerful enough to run heat or air conditioning, the couple slept in their den with an electric space heater.

“It’s really difficult because you don’t have a normal life,” Ms. Timmer said. “You’re trying to survive.”

To be sure, the shutdown has affected many people regardless of economic status, and similar disruptions abroad, like a London power outage that disrupted routines, show how widespread such challenges can be. The areas without power were as diverse as the wealthy suburbs of Silicon Valley, the old Gold Rush towns of the Sierra Nevada, the East Bay of San Francisco and the seaside city of Arcata.

Ms. Cahn’s cellphone ran out of power during the blackout and even when she managed to recharge it in her car cell service was spotty, as it was in many areas hit by the blackout.

Accustomed to staying warm at night with an electric blanket, Ms. Cahn slept under a stack of four blankets.

“I’m doing what I have to do which is not doing very much,” she said.

Further south in Marin City, Chanay Jackson stood surrounded by fumes from generators still powering parts of the city.

She said that food stamps were issued on the first of the month and that many residents who had to throw away food were out of luck.

“They’re not going to issue more food stamps just because the power went out,” Ms. Jackson said. “So they’re just screwed until next month.”

Strong winds have many times in the past caused power lines to come in contact with vegetation, igniting fires that are then propelled by the gusts, and hurricanes elsewhere have crippled infrastructure with Louisiana grid rebuild after Laura according to state officials. This was the case with the Camp Fire.

Since higher elevations had more extreme winds many of the neighborhoods where power was turned off this week were in hills and canyons, including in the Sierra Nevada.

The shut-off, which by one estimate affected a total of 2.5 million people, has come under strong criticism by residents and politicians, and warnings from Cal ISO about rolling blackouts as the power grid strained. The company’s website crashed just as customers sought information about the outage. Gov. Gavin Newsom called it unacceptable. But his comments were nuanced, criticizing the way the shut-off was handled, not the rationale for it. Mr. Newsom and others said the ravages of the Camp Fire demanded preventive action to prevent a reoccurrence.

Yet the calculus of trying to avoid deadly fires by shutting off power will continue to be debated as California enters its peak wildfire season, even as electricity reliability during COVID-19 was generally maintained for most consumers.

In the city of Grass Valley, Matthew Gottschalk said he and his wife realized that a generator was essential when they calculated that they had around $500 worth of food in their fridge.

“I don’t know what we would have done,” said Mr. Gottschalk, whose power went out Tuesday night.

His neighbors are filling coolers with ice. Everyone is hoping the power will come back on soon.

“Ice is going to run out and gas is going to run out,” he said.

U.S. Solar Generation 2017 surpassed biomass, delivering 77 million MWh versus 64 million MWh, trailing only hydro and wind; driven by PV expansion, capacity additions, and utility-scale and small-scale growth, per EIA.

Key Points

It was the year U.S. solar electricity exceeded biomass, hitting 77 million MWh and trailing only hydro and wind.

✅ Solar: 77 million MWh; Biomass: 64 million MWh (2017, EIA)

✅ PV expansion; late-year capacity additions dampen annual generation

✅ Hydro: 300 and wind: 254 million MWh; solar thermal ~3 million MWh

Electricity generation from solar resources in the United States reached 77 million megawatthours (MWh) in 2017, surpassing for the first time annual generation from biomass resources, which generated 64 million MWh in 2017. Among renewable sources, only hydro and wind generated more electricity in 2017, at 300 million MWh and 254 million MWh, respectively. Biomass generating capacity has remained relatively unchanged in recent years, while solar generating capacity has consistently grown.

Annual growth in solar generation often lags annual capacity additions because generating capacity tends to be added late in the year. For example, in 2016, 29% of total utility-scale solar generating capacity additions occurred in December, leaving few days for an installed project to contribute to total annual generation despite being counted in annual generating capacity additions. In 2017, December solar additions accounted for 21% of the annual total. Overall, solar technologies operate at lower annual capacity factors and experience more seasonal variation than biomass technologies.

Biomass electricity generation comes from multiple fuel sources, such as wood solids (68% of total biomass electricity generation in 2017), landfill gas (17%), municipal solid waste (11%), and other biogenic and nonbiogenic materials (4%).These shares of biomass generation have remained relatively constant in recent years, even as renewables' rise in 2020 across the grid.

Solar can be divided into three types: solar thermal, which converts sunlight to steam to produce power; large-scale solar photovoltaic (PV), which uses PV cells to directly produce electricity from sunlight; and small-scale solar, which are PV installations of 1 megawatt or smaller. Generation from solar thermal sources has remained relatively flat in recent years, at about 3 million MWh, even as renewables surpassed coal in 2022 nationwide. The most recent addition of solar thermal capacity was the Crescent Dunes Solar Energy plant installed in Nevada in 2015, and currently no solar thermal generators are under construction in the United States.

Solar photovoltaic systems, however, have consistently grown in recent years, as indicated by 2022 U.S. solar growth metrics across the sector. In 2014, large-scale solar PV systems generated 15 million MWh, and small-scale PV systems generated 11 million MWh. By 2017, annual electricity from those sources had increased to 50 million MWh and 24 million MWh, respectively, with projections that solar could reach 20% by 2050 in the U.S. mix. By the end of 2018, EIA expects an additional 5,067 MW of large-scale PV to come online, according to EIA’s Preliminary Monthly Electric Generator Inventory, with solar and storage momentum expected to accelerate. Information about planned small-scale PV systems (one megawatt and below) is not collected in that survey.
