Springtime in Arizona is a great time for yard work, swimming and many other outdoor activities. No matter whatÂ’s on your outdoor agenda, electrical safety should be an important part of your plans.

UniSource Energy Services offers 10 tips to help you play it safe around electricity when youÂ’re outdoors this spring.

1. Always keep power cords and electrical equipment away from water or other wet areas.

2. Look up and look out for overhead power lines. Be sure youÂ’re aware of any nearby lines before you climb a ladder or extend the handle of a pool-cleaning tool.

3. Call before you dig. Whether youÂ’re a homeowner landscaping your yard or a professional contractor digging utility trenches, remember to call 811 or Arizona Blue Stake at 1-800-STAKE-IT (1-800-782-5348) at least two working days before you dig. ItÂ’s a free service, and itÂ’s required by state law.

4. Keep materials, tools and all parts of your body at least 15 feet away from any overhead power lines at all times, including during the installation of antennas or satellite dishes. If you plan to get any closer, state law requires you to make arrangements with UES – at your expense – that will allow your work to proceed safely. Contact Arizona Blue Stake at the number listed above to make these arrangements.

5. Never fly kites or model airplanes near power lines or radio or TV antennas. If a kite does get tangled with overhead lines, donÂ’t try to get it down yourself, as a kite string can conduct electricity. Instead, call UES for assistance.

6. Before every use, inspect power tools and electric lawn mowers for frayed power cords, broken plugs and weathered or damaged housings. DonÂ’t use damaged equipment until it has been repaired properly. Keep tools unplugged and stored in dry areas when they are not in use.

7. Before you trim tree limbs and shrubs, watch out for power lines that could be hidden by foliage. Contact UES if there are concerns about tree limbs growing into or around overhead power lines on your property.

8. Keep vegetation and permanent structures away from the green, ground-level boxes that house components of an underground electrical system. UES workers may need to access the lines and equipment near these boxes during power outages or for routine maintenance.

9. Do not use electric-powered mowers on wet grass or around water. Always use an insulated extension cord designed for outdoor use with the correct power rating for that equipment.

10. Treat all electric lines with caution and respect. Even low-voltage electric lines and cords can be hazardous if damaged or improperly handled.

UES, a subsidiary of UniSource Energy Corporation, provides natural gas and electric service to about 236,000 customers across Arizona. For more information about UES, visit uesaz.com. For more information about UniSource Energy, visit uns.com.

U.S. Electric Vehicle Market Share Dips in Q1 2024

U.S. EV Market Share Dip Q1 2024 reflects slower BEV adoption, rising PHEV demand, affordability concerns, charging infrastructure gaps, tax credit shifts, range anxiety, and automaker strategy adjustments across the electric vehicle market.

 

Key Points

Q1 2024 EV and hybrid share slipped as BEV sales lag, PHEVs rise, and affordability and charging concerns temper demand.

✅ BEV share fell to 7.0% as affordable models remain limited

✅ PHEV sales rose 50% YoY, easing range anxiety concerns

✅ Policy shifts and charging gaps weigh on consumer adoption

 

The U.S. electric vehicle (EV) market, once a beacon of unbridled growth, appears to be experiencing a course correction. Data from the U.S. Energy Information Administration (EIA) reveals that the combined market share of electric vehicles (battery electric vehicles, or BEVs) and hybrids dipped slightly in the first quarter of 2024, marking the first decline since the onset of the COVID-19 pandemic, even as EU EV share rose during lockdowns in 2020.

This news comes as a surprise to many analysts who predicted continued exponential growth for the EV market. While overall sales of electric vehicles surged into 2024 and did increase by 7% compared to Q1 2023, this growth wasn't enough to keep pace with the overall rise in vehicle sales. The result: a decline in market share from 18.8% in Q4 2023 to 18.0% in Q1 2024.

Several factors may be contributing to this shift. One potential culprit is a slowdown in battery electric vehicle sales. BEVs saw their share of the market dip from 8.1% to 7.0% in the same period. This could be attributed to a lack of readily available affordable options, with many popular EV models still commanding premium prices and concerns that EV supply may miss demand in the near term.

Another factor could be the rising interest in plug-in hybrid electric vehicles (PHEVs). PHEV sales witnessed a significant jump of 50% year-over-year, reflecting how gas-electric hybrids are getting a boost from major automakers, potentially indicating a consumer preference for vehicles that offer both electric and gasoline powertrain options, addressing concerns about range anxiety often associated with BEVs.

Industry experts offer mixed interpretations of this data. Some downplay the significance of the dip, attributing it to a temporary blip, even though EVs remain behind gas cars in total sales. They point to the ongoing commitment from major automakers to invest in EV production and the potential for new, more affordable models to hit the market soon.

Others express more concern, citing Europe's recent EV slump and suggesting this might be a sign of maturing consumer preferences. They argue that simply increasing the number of EVs on the market might not be enough. Automakers need to address issues like affordability, charging infrastructure, and range anxiety to maintain momentum.

The role of government incentives also remains a question mark. The federal tax credit for electric vehicles is currently set to phase out gradually, potentially impacting consumer purchasing decisions in the future. Continued government support, through incentives or infrastructure development, could be crucial in maintaining consumer interest.

The coming quarters will be crucial in determining the long-term trajectory of the U.S. EV market, especially after the global electric car market's rapid expansion in recent years. Whether this is a temporary setback or a more lasting trend remains to be seen. Addressing consumer concerns, ensuring a diverse range of affordable EV options, and continued government support will all be essential in ensuring the continued growth of this critical sector.

This development also presents an opportunity for traditional automakers. By capitalizing on the growing PHEV market and addressing consumer concerns about affordability and range anxiety, they can carve out a strong position in the evolving automotive landscape.

Solar PV and wind power in the US continue to grow amid favourable government plans

US Renewable Power Outlook 2030 projects surging capacity, solar PV and wind growth, grid modernization, and favorable tax credits, detailing market trends, CAGR, transmission expansion, and policy drivers shaping clean energy generation and consumption.

 

Key Points

A forecast of US power capacity, generation, and consumption, highlighting solar, wind, tax credits, and grid modernization.

✅ Targets 48.4% renewable capacity share by 2030

✅ Strong growth in solar PV and onshore wind installations

✅ Investment and tax credits drive grid and transmission upgrades

 

GlobalData’s latest report, ‘United States Power Market Outlook to 2030, Update 2021 – Market Trends, Regulations, and Competitive Landscape’ discusses the power market structure of the United States and provides historical and forecast numbers for capacity, generation and consumption up to 2030. Detailed analysis of the country’s power market regulatory structure, competitive landscape and a list of major power plants are provided. The report also gives a snapshot of the power sector in the country on broad parameters of macroeconomics, supply security, generation infrastructure, transmission and distribution infrastructure, about a quarter of U.S. electricity from renewables in recent years, electricity import and export scenario, degree of competition, regulatory scenario, and future potential. An analysis of the deals in the country’s power sector is also included in the report.

Renewable power held a 19% share of the US’s total power capacity in 2020, and in that year renewables became the second-most prevalent source in the U.S. electricity mix by generation; this share is expected to increase significantly to 48.4% by 2030. Favourable policies introduced by the US Government will continue to drive the country’s renewable sector, particularly solar photovoltaics (PV) and wind power, with wind now the most-used renewable source in the U.S. generation mix. Installed renewable capacity* increased from 16.5GW in 2000 to 239.2GW in 2020, growing at a compound annual growth rate (CAGR) of 14.3%. By 2030, the cumulative renewable capacity is expected to rise to 884.6GW, growing at a CAGR of 14% from 2020 to 2030. Despite increase in prices of renewable equipment, such as solar modules, in 2021, the US renewable sector will show strong growth during the 2021 to 2030 period as this increase in equipment prices are short term due to supply chain disruptions caused by the Covid-19 pandemic.

The expansion of renewable power capacity during the 2000 to 2020 period has been possible due to the introduction of federal schemes, such as Production Tax Credits, Investment Tax Credits and Manufacturing Tax Credits. These have massively aided renewable installations by bringing down the cost of renewable power generation and making it at par with power generated from conventional sources. Over the last few years, the cost of solar PV and wind power installations has declined sharply, and by 2023 wind, solar, and batteries made up most of the utility-scale pipeline across the US, highlighting investor confidence. Since 2010, the cost of utility-scale solar PV projects decreased by around 82% while onshore wind installations decreased by around 39%. This has supported the rapid expansion of the renewable market. However, the price of solar equipment has risen due to an increase in raw material prices and supply shortages. This may slightly delay the financing of some solar projects that are already in the pipeline.

The US will continue to add significant renewable capacity additions during the forecast period as industry outlooks point to record solar and storage installations over the coming years, to meet its target of reaching 80% clean energy by 2030. In November 2021, President Biden signed a $1tr Infrastructure Bill, within which $73bn is designated to renewables. This includes not just renewable capacity building, but also strengthening the country’s power grid and laying new high voltage transmission lines, both of which will be key to driving solar and wind power capacity additions as wind power surges in the U.S. electricity mix nationwide.

The US was one of the worst hit countries in the world due to the Covid-19 pandemic in 2020. With respect to the power sector, the electricity consumption in the country declined by 2.5% in 2020 as compared to 2019, even as renewable electricity surpassed coal in 2022 in the generation mix, highlighting continued structural change. Power plants that were under construction faced delays due to unavailability of components due to supply chain disruptions and unavailability of labour due to travel restrictions.

According to the US Energy Information Administration, 61 power projects, having a total capacity of 2.4GWm which were under construction during March and April 2020 were delayed because of the Covid-19 pandemic. Among renewable power technologies, solar PV and wind power projects were the most badly affected due to the pandemic.

In March and April 2020, 53 solar PV projects, having a total capacity of 1.3GW, and wind power projects, having a total capacity of 1.2GW, were delayed due to the Covid-19 pandemic. Moreover, several states suspended renewable energy auctions due to the pandemic.

For instance, New York State Energy Research and Development Authority (NYSERDA) had issued a new offshore wind solicitation for 1GW and up to 2.5GW in April 2020, but this was suspended due to the Covid-19 pandemic. In July 2020, the authority relaunched the tender for 2.5GW of offshore wind capacity, with a submission deadline in October 2020.

To ease the financial burden on consumers during the pandemic, more than 1,000 utilities in the country announced disconnection moratoria and implemented flexible payment plans. Duke Energy, American Electric Power, Dominion Power and Southern California Edison were among the major utilities that voluntarily suspended disconnections.

ABO to build 10MW Tunisian solar park

ABO Wind Tunisia 10MW Solar Project will build a photovoltaic park in Gabes with a STEG PPA, fixed tariff, 2,500 m grid connection, producing 18 million kWh annually, targeted for 2020 commissioning with local partners.

 

Key Points

A 10MW photovoltaic park in Gabes with a 20-year STEG PPA and fixed tariff, slated for 2020 commissioning.

✅ 18 million kWh/year; 2,500 m grid tie, 20-year fixed tariff

✅ Electricity supplied to STEG under PPA; 2020 commissioning

✅ Located in Gabes; built with local partners, 10MW capacity

 

ABO Wind has received a permit and a tariff for a 10MW photovoltaic project in Tunisia, amid global activity such as Spain's 90MW wind project now underway, which it plans to build and commission in 2020.

The solar park, in the governorate of Gabes, is 400km south of the country’s capital Tunis and aligns with renewable funding initiatives seen across developing markets.

The developer said it plans to build the project next year in close cooperation with local partners, as regional markets from North Africa to the Gulf expand, with Saudi Arabia boosting wind capacity as well.

ABO Wind department head Nicolas Konig said: “The solar park will produce more than 18 million kilowatt hours of electricity per year and will feed it into the grid at a distance of 2500 metres.”

The developer will conclude an electricity supply contract with the state-owned energy supplier (Societe tunisienne de l’electricite et du gaz (STEG), which will provide a fixed remuneration over 20 years, a model echoed by Germany's wind-solar tender for the electricity fed into the grid.

Earlier this year, ABO Wind had already secured a tariff for a wind farm with a capacity of 30MW in a tender, 35km south-east of Tunis, underscoring Tunisia's wind investments under its long-term plan.

The company is working on half a dozen Tunisian wind and solar projects, as institutions like the World Bank support wind growth in developing countries.

“We are making good progress on our way to assemble a portfolio of several ready-to-build wind and solar projects attractive to investors, as Saudi clean energy targets continue to expand globally,” said ABO Wind general manager responsible for international business development Patrik Fischer.

Climate Solution: Use Carbon Dioxide to Generate Electricity

Methane Hydrate CO2 Sequestration uses carbon capture and nitrogen injection to swap gases in seafloor hydrates along the Gulf of Mexico, releasing methane for electricity while storing CO2, according to new simulation research.

 

Key Points

A method injecting CO2 and nitrogen into hydrates to store CO2 while releasing methane for power.

✅ Nitrogen aids CO2-methane swap in hydrate cages, speeding sequestration

✅ Gulf Coast proximity to emitters lowers transport and power costs

✅ Revenue from methane electricity could offset carbon capture

 

The world is quickly realizing it may need to actively pull carbon dioxide out of the atmosphere to stave off the ill effects of climate change. Scientists and engineers have proposed various carbon capture techniques, but most would be extremely expensive—without generating any revenue. No one wants to foot the bill.

One method explored in the past decade might now be a step closer to becoming practical, as a result of a new computer simulation study. The process would involve pumping airborne CO2 down into methane hydrates—large deposits of icy water and methane right under the seafloor, beneath water 500 to 1,000 feet deep—where the gas would be permanently stored, or sequestered. The incoming CO2 would push out the methane, which would be piped to the surface and burned to generate electricity, whether sold locally or via exporters like Hydro-Que9bec to help defray costs, to power the sequestration operation or to bring in revenue to pay for it.

Many methane hydrate deposits exist along the Gulf of Mexico shore and other coastlines. Large power plants and industrial facilities that emit CO2 also line the Gulf Coast, where EPA power plant rules could shape deployment, so one option would be to capture the gas directly from nearby smokestacks, keeping it out of the atmosphere to begin with. And the plants and industries themselves could provide a ready market for the electricity generated.

A methane hydrate is a deposit of frozen, latticelike water molecules. The loose network has many empty, molecular-size pores, or “cages,” that can trap methane molecules rising through cracks in the rock below. The computer simulation shows that pushing out the methane with CO2 is greatly enhanced if a high concentration of nitrogen is also injected, and that the gas swap is a two-step process. (Nitrogen is readily available anywhere, because it makes up 78 percent of the earth’s atmosphere.) In one step the nitrogen enters the cages; this destabilizes the trapped methane, which escapes the cages. In a separate step, the nitrogen helps CO2 crystallize in the emptied cages. The disturbed system “tries to reach a new equilibrium; the balance goes to more CO2 and less methane,” says Kris Darnell, who led the study, published June 27 in the journal Water Resources Research. Darnell recently joined the petroleum engineering software company Novi Labs as a data scientist, after receiving his Ph.D. in geoscience from the University of Texas, where the study was done.

A group of labs, universities and companies had tested the technique in a limited feasibility trial in 2012 on Alaska’s North Slope, where methane hydrates form in sandstone under deep permafrost. They sent CO2 and nitrogen down a pipe into the hydrate. Some CO2 ended up being stored, and some methane was released up the same pipe. That is as far as the experiment was intended to go. “It’s good that Kris [Darnell] could make headway” from that experience, says Ray Boswell at the U.S. Department of Energy’s National Energy Technology Laboratory, who was one of the Alaska experiment leaders but was not involved in the new study. The new simulation also showed that the swap of CO2 for methane is likely to be much more extensive—and to happen quicker—if CO2 enters at one end of a hydrate deposit and methane is collected at a distant end.

The technique is somewhat similar in concept to one investigated in the early 2010s by Steven Bryant and others at the University of Texas. In addition to numerous methane hydrate deposits, the Gulf Coast has large pools of hot, salty brine in sedimentary rock under the coastline. In this system, pumps would send CO2 down into one end of a deposit, which would force brine into a pipe that is placed at the other end and leads back to the surface. There the hot brine would flow through a heat exchanger, where heat could be extracted and used for industrial processes or to generate electricity, supporting projects such as electrified LNG in some markets. The upwelling brine also contains some methane that could be siphoned off and burned. The CO2 dissolves into the underground brine, becomes dense and sinks further belowground, where it theoretically remains.

Either system faces big practical challenges, and building shared CO2 storage hubs to aggregate captured gas is still evolving. One is creating a concentrated flow of CO2; the gas makes up only .04 percent of air, and roughly 10 percent of the smokestack emission from a typical power plant or industrial facility. If an efficient methane hydrate or brine system requires an input that is 90 percent CO2, for example, concentrating the gas will require an enormous amount of energy—making the process very expensive. “But if you only need a 50 percent concentration, that could be more attractive,” says Bryant, who is now a professor of chemical and petroleum engineering at the University of Calgary. “You have to reduce the [CO2] capture cost.”

Another major challenge for the methane hydrate approach is how to collect the freed methane, which could simply seep out of the deposit through numerous cracks and in all directions. “What kind of well [and pipe] structure would you use to grab it?” Bryant asks.

Given these realities, there is little economic incentive today to use methane hydrates for sequestering CO2. But as concentrations rise in the atmosphere and the planet warms further, and as calls for an electric planet intensify, systems that could capture the gas and also provide energy or revenue to run the process might become more viable than techniques that simply pull CO2 from the air and lock it away, offering nothing in return.

PG&E keeps nearly 60,000 Northern California customers in the dark to reduce wildfire risk

PG&E Public Safety Power Shutoff reduces wildfire risk during extreme winds, triggering de-energization across the North Bay and Sierra Foothills under red flag warnings, with safety inspections and staged restoration to improve grid resilience.

 

Key Points

A utility protocol to de-energize lines during extreme fire weather, reducing ignition risks and improving grid safety.

✅ Triggered by red flag warnings, humidity, wind, terrain

✅ Temporary de-energization of transmission and distribution lines

✅ Inspections precede phased restoration to minimize wildfire risk

 

PG&E purposefully shut off electricity to nearly 60,000 Northern California customers Sunday night, aiming to mitigate wildfire risks from power lines during extreme winds.

Pacific Gas and Electric planned to restore power to 70 percent of affected customers in the North Bay and Sierra Foothills late Monday night. As crews inspect lines for safety by helicopter, vehicles and on foot, the remainder will have power sometime Tuesday.

While it was the first time the company shut off power for public safety, PG&E announced its criteria and procedures for such an event in June, said spokesperson Paul Doherty. After wildfires devastated Northern California's wine country last October, he added, PG&E developed its community wildfire safety program division to make power grids and communities more resilient, and prepares for winter storm season through enhanced local response. 

Two sagging PG&E power lines caused one of those wildfires during heavy winds, killing four people and injuring a firefighter, the California Department of Forestry and Fire Protection determined earlier this month. Trees or tree branches hitting PG&E power lines started another four wildfires in October 2017. Altogether, the power company has been blamed for igniting 13 wildfires last year.

"We're adapting our electric system our operating practices to improve safety and reliability," Doherty said of the safety program. "That's really the bottom line for us."

Turning off power to so many customers was a "last resort given the extreme fire danger conditions these communities are experiencing," Pat Hogan, senior vice president of electric operations, said in a statement. Conditions that led the company to shut off power included the National Weather Service's red flag fire warnings, humidity levels, sustained winds, temperature, dry fuel and local terrain, Doherty said, amid possible rolling blackouts during grid strain.

The company de-energized more than 78 miles of transmission lines and more than 2,150 miles of distribution power lines Sunday night. Many schools in the area were closed Monday because of the planned power outage, highlighting unequal access to electricity across communities.

Late Saturday and early Sunday, PG&E warned 97,000 customers in 12 counties that the shut off might go into effect. Through automated calls, texts and emails, the company encouraged customers to have drinking water, canned food, flashlights, prescriptions and baby supplies on hand.

Power was also turned off in Southern California on Monday.

San Diego Gas & Electric turned off service to about 360 customers near Cleveland National Forest, where multiple fires have scorched large swaths of land in recent years.

SDG&E has pre-emptively shut off power to customers in the past, most recently in December when 14,000 customers went without power.

Southern California Edison, the primary electric provider across Southern California — including Los Angeles — has a similar power shutoff program. As of Monday night, SCE had yet to turn off power in any of its service areas, a spokesperson told USA TODAY.

Mines found at Ukraine's Zaporizhzhia nuclear plant, UN watchdog says

Zaporizhzhia Nuclear Plant Mines reported by IAEA at the Russian-occupied site: anti-personnel devices in a buffer zone, restricted areas; access limits to reactor rooftops and turbine halls heighten nuclear safety and security concerns in Ukraine.

 

Key Points

IAEA reports anti-personnel mines at Russian-held Zaporizhzhia, raising nuclear safety risks in buffer zones.

✅ IAEA observes mines in buffer zone at occupied site

✅ Restricted areas; no roof or turbine hall access granted

✅ Safety systems unaffected, but staff under pressure

 

The United Nations atomic watchdog said it saw anti-personnel mines at the site of Ukraine's Zaporizhzhia nuclear power plant which is occupied by Russian forces.

Europe's largest nuclear facility fell to Russian forces shortly after the invasion of Ukraine in February last year, as Moscow later sought to build power lines to reactivate it amid ongoing control of the area. Kyiv and Moscow have since accused each other of planning an incident at the site.

On July 23 International Atomic Energy Agency (IAEA) experts "saw some mines located in a buffer zone between the site's internal and external perimeter barriers," agency chief Rafael Grossi said in a statement on Monday.

The statement did not say how many mines the team had seen.

The devices were in "restricted areas" that operating plant personnel cannot access, Mr Grossi said, adding the IAEA's initial assessment was that any detonation "should not affect the site's nuclear safety and security systems".

Laying explosives at the site was "inconsistent with the IAEA safety standards and nuclear security guidance" and, amid controversial proposals on Ukraine's nuclear plants that have circulated internationally, created additional psychological pressure on staff, he added.

Ukrainians in Nikopol are out of water and within Russia's firing line. But Zaporizhzhia nuclear power plant could pose the biggest threat, even as Ukraine has resumed electricity exports to regional grids.

Last week the IAEA said its experts had carried out inspections at the plant, without "observing" the presence of any mines, although they had not been given access to the rooftops of the reactor buildings, while a possible agreement to curb attacks on plants was being discussed.

The IAEA had still not been given access to the roofs of the reactor buildings and their turbine halls, its latest statement said, even as a proposal to control Ukraine's nuclear plants drew scrutiny.

After falling into Russian hands, Europe's biggest power plant was targeted by gunfire and has been severed from the grid several times, raising nuclear risk warnings from the IAEA and others.

The six reactor units, which before the war produced around a fifth of Ukraine's electricity, have been shut down for months, prompting interest in wind power development as a harder-to-disrupt source.
