Did you ever see Dallas from a DC-9 at night?

Well Dallas is a jewel, oh yeah, Dallas is a beautiful sight. And Dallas is a jungle, but Dallas gives a beautiful light. Songwriter Jimmie Dale Gilmore's love letter to Big D's skyline evokes visions of Reunion Tower's blinking bulbs, the Bank of America building's green neon glow and the blazing red hues of Pegasus, perched atop downtown's Magnolia Hotel.

But these and thousands of other city lights could fall dark four hours each night under an ordinance Dallas City Council members will consider as part of a broader effort to conserve energy and reduce power plant emissions. According to an ordinance draft, businesses citywide would be required to switch off most of their exterior and signage lighting between 2 a.m. and 6 a.m. That includes:

- Decorative lighting, "such as lighting that illuminates or outlines a building's facades or elements";

- Lighting used to illuminate fountains, sculptures, flagpoles and other similar structures;

- Landscape illumination lighting;

- Lighting that illuminates premise signs, whether attached to or separate from a building.

Violators could face fines of up to $2,000. Among the ordinance's exemptions are security, hospital, traffic control, residential and transportation lighting. State and federal government facilities, as well as businesses open and operating between 2 a.m. and 6 a.m., would also be exempt, according to the ordinance.

"I applaud any of the efforts the city is trying to implement to try and get us to conserve. But we are a home for people who come from outside - a beacon for location," said Steve Vissotzky, general manager of the Hyatt Regency Dallas, which includes Reunion Tower - perhaps the city's best-known structure.

"It's really a landmark, and it gives people direction to my hotel. I would hope they'd include an exception for that." Said John Crawford, executive director of the business organization Downtown Dallas: "Dallas has a very unique skyline, and for that to go dark would take away from how people perceive the city.

If this is going to be a 24-7 downtown, I don't think that his ordinance will go over well with the people and businesses here." But Ann Drum, chairwoman of the Dallas Sierra Club, argues the benefits of slashing energy consumption citywide far outweigh the potential drawbacks of businesses going dark during hours when most Dallasites are sound asleep. "Are we trying to get more people on the streets between 2 a.m. and 6 a.m.? Is that a priority in this city?" Ms. Drum asked. "We should do anything we can do to reduce our usage of energy or emission that cause greenhouse gases so long as it doesn't significantly harm our quality of life. It sounds like a pretty commonsense plan to me."

Several city council members agree that Dallas must attempt to implement aggressive environmental regulations in a time when Dallas County's air quality is consistently poor during summer months. The council Wednesday will also consider strict regulations on idling trucks, pollutant-belching vehicles and where the city purchases its cement, among other measures. But even the council's most strident environmentalists say the lighting ordinance as written may require tweaking.

"The lighting ordinance would save an enormous amount of money and energy citywide," said Mayor Laura Miller, who's led efforts to prevent TXU Corp. from building traditional, coal-fired power plants in Texas that she says will degrade the region's air quality. "But you don't want to lop off your nose to spite your face. We may be more likely to require that premise signs be turned off. We'll have a good discussion about the rest" of the draft ordinance. City officials could not immediately provide estimates of how much energy Dallas would save, or how many tons of emissions would be prevented, through its ordinance.

At this juncture, the council should remain open to all energy reduction ideas, Deputy Mayor Pro Tem Elba Garcia said. "Dallas has been in the forefront of environmental issues recently, and this is a first good step in an effort to conserve energy - and it's a great opportunity for the council to discuss the issue," Dr. Garcia said.

District 11 City Council member Linda Koop, chairwoman of the council's Transportation and Environment Committee, says she expects the council to vote on portions of the overall emissions reduction plan Wednesday, but may further study elements of the ordinance. "We'll just have to have that conversation and see," Ms. Koop said.

"Obviously, there are benefits to the ordinance, in that it decreases energy consumption, which decreases emissions. There are probably some things we can do to address decorative lighting, though." The Tucson, Ariz.-based International Dark-Sky Association estimates more than 1,000 U.S. cities have passed some sort of "dark skies" ordinance. District 12 City Council member Ron Natinsky, for one, isn't convinced Dallas needs to join in.

Energy-hungry Europe to brighten profit at US solar equipment makers

European Solar Inverter Demand surges as photovoltaics and residential solar expand during the clean energy transition, driven by high natural gas prices; Germany leads, boosting Enphase and SolarEdge sales for rooftop systems and grid-tied installations.

 

Key Points

Rising European need for solar inverters, fueled by residential PV growth, high energy costs, and clean energy policies.

✅ Germany leads EU rooftop PV installations

✅ Enphase and SolarEdge see revenue growth

✅ High gas prices and policies spur adoption

 

Solar equipment makers are expected to post higher quarterly profit, benefiting from strong demand in Europe for critical components that convert energy from the sun into electricity, amid record renewable momentum worldwide.

The continent is emerging as a major market for solar firms as it looks to reduce its dependence on the Russian energy supply and accelerate its clean energy transition, with solar already reshaping power prices in Northern Europe across the region, brightening up businesses of companies such as Enphase Energy (ENPH.O) and SolarEdge Technologies (SEDG.O), which make solar inverters.

Wall Street expects Enphase and SolarEdge to post a combined adjusted net income of $323.8 million for the April-June quarter, a 56.7% jump from a year earlier, even as demand growth slows in the United States.

The energy crisis in Europe is not as acute as last year when Western sanctions on Russia severely crimped supplies, but prices of natural gas and electricity continue to be much higher than in the United States, Raymond James analyst Pavel Molchanov said.

As a result, demand for residential solar keeps growing at a strong pace in the region, with Germany being one of the top markets and solar adoption in Poland also accelerating in recent years across the region.

About 159,000 residential solar systems became operational in the first quarter in Germany amid a solar power boost that reflects policy and demand, a 146% rise from a year earlier, according to BSW solar power association.

Adoption of solar is also helping European homeowners have greater control over their energy costs as fossil fuel prices tend to be more volatile, Morningstar analyst Brett Castelli said.

SolarEdge, which has a bigger exposure to Europe than Enphase, said its first-quarter revenue from the continent more than doubled compared with last year.

In comparison, growth in the United States has been tepid due to lukewarm demand in states like Texas and Arizona where cheaper electricity prices make the economics of residential solar less attractive, even though solar is now cheaper than gas in parts of the U.S. market.

Higher interest rates following the U.S. Federal Reserve's recent actions to tame inflation are also weighing on demand, even as power outage risks rise across the United States.

Analysts also expect weakness in California where a new metering reform reduces the money credited to rooftop solar owners for sending excess power into the grid, underscoring how policy shifts can reshape the sector. The sunshine state accounts for nearly a third of the U.S. residential solar market.

Enphase will report its results on Thursday after the bell, while SolarEdge will release its second-quarter numbers on Aug. 1.

Scientists Built a Genius Device That Generates Electricity 'Out of Thin Air'

Air-gen Protein Nanowire Generator delivers clean energy by harvesting ambient humidity via Geobacter-derived conductive nanowires, generating continuous hydrovoltaic electricity through moisture gradients, electrodes, and proton diffusion for sustainable, low-waste power in diverse climates.

 

Key Points

A device using Geobacter protein nanowires to harvest humidity, producing continuous DC power via proton diffusion.

✅ 7 micrometer film between electrodes adsorbs water vapor.

✅ Output: ~0.5 V, 17 uA/cm2; stack units to scale power.

✅ Geobacter optimized via engineered E. coli for mass nanowires.

 

They found it buried in the muddy shores of the Potomac River more than three decades ago: a strange "sediment organism" that could do things nobody had ever seen before in bacteria.

This unusual microbe, belonging to the Geobacter genus, was first noted for its ability to produce magnetite in the absence of oxygen, but with time scientists found it could make other things too, like bacterial nanowires that conduct electricity.

For years, researchers have been trying to figure out ways to usefully exploit that natural gift, and they might have just hit pay-dirt with a device they're calling the Air-gen. According to the team, their device can create electricity out of… well, almost nothing, similar to power from falling snow reported elsewhere.

"We are literally making electricity out of thin air," says electrical engineer Jun Yao from the University of Massachusetts Amherst. "The Air-gen generates clean energy 24/7."

The claim may sound like an overstatement, but a new study by Yao and his team describes how the air-powered generator can indeed create electricity with nothing but the presence of air around it. It's all thanks to the electrically conductive protein nanowires produced by Geobacter (G. sulfurreducens, in this instance).

The Air-gen consists of a thin film of the protein nanowires measuring just 7 micrometres thick, positioned between two electrodes, referencing advances in near light-speed conduction in materials science, but also exposed to the air.

Because of that exposure, the nanowire film is able to adsorb water vapour that exists in the atmosphere, offering a contrast to legacy hydropower models, enabling the device to generate a continuous electrical current conducted between the two electrodes.

The team says the charge is likely created by a moisture gradient that creates a diffusion of protons in the nanowire material.

"This charge diffusion is expected to induce a counterbalancing electrical field or potential analogous to the resting membrane potential in biological systems," the authors explain in their study.

"A maintained moisture gradient, which is fundamentally different to anything seen in previous systems, explains the continuous voltage output from our nanowire device."

The discovery was made almost by accident, when Yao noticed devices he was experimenting with were conducting electricity seemingly all by themselves.

"I saw that when the nanowires were contacted with electrodes in a specific way the devices generated a current," Yao says.

"I found that exposure to atmospheric humidity was essential and that protein nanowires adsorbed water, producing a voltage gradient across the device."

Previous research has demonstrated hydrovoltaic power generation using other kinds of nanomaterials – such as graphene-based systems now under study – but those attempts have largely produced only short bursts of electricity, lasting perhaps only seconds.

By contrast, the Air-gen produces a sustained voltage of around 0.5 volts, with a current density of about 17 microamperes per square centimetre, and complementary fuel cell solutions can help keep batteries energized, with a current density of about 17 microamperes per square centimetre. That's not much energy, but the team says that connecting multiple devices could generate enough power to charge small devices like smartphones and other personal electronics – concepts akin to virtual power plants that aggregate distributed resources – all with no waste, and using nothing but ambient humidity (even in regions as dry as the Sahara Desert).

"The ultimate goal is to make large-scale systems," Yao says, explaining that future efforts could use the technology to power homes via nanowire incorporated into wall paint, supported by energy storage for microgrids to balance supply and demand.

"Once we get to an industrial scale for wire production, I fully expect that we can make large systems that will make a major contribution to sustainable energy production."

If there is a hold-up to realising this seemingly incredible potential, it's the limited amount of nanowire G. sulfurreducens produces.

Related research by one of the team – microbiologist Derek Lovley, who first identified Geobacter microbes back in the 1980s – could have a fix for that: genetically engineering other bugs, like E. coli, to perform the same trick in massive supplies.

"We turned E. coli into a protein nanowire factory," Lovley says.

"With this new scalable process, protein nanowire supply will no longer be a bottleneck to developing these applications."

Russian state atomic energy corporation Rosatom and the Russian State Academy of Sciences are to cooperate on joint scientific, technical and innovative activities in areas including nuclear energy, nuclear medicine and other areas of the electricity sector under an agreement signed in Moscow on 7 February.

The cooperation agreement was signed by Rosatom Director General Alexei Likhachov and President of the Russian Academy of Sciences Alexander Sergeev during a joint meeting to mark Russian Science Day. Under its terms, the partners will cooperate in organising research and development activities aimed at providing technological advantages in various sectors of the domestic industry, as well as creating and developing interdisciplinary scientific and technological centres and organisations supporting energy sector training and innovation. They will also jointly develop strategic planning documents, improve the technical and scientific regulatory and legal framework, and carry out expert evaluations of scientific and technical projects and scientific consultations.

Rosatom said the main areas of cooperation in the agreement are: the development of laser technologies and particle accelerators; the creation of modern diagnostic equipment, nuclear medicine and radiation therapy; controlled thermonuclear fusion; nuclear energy of the future; new materials; the nuclear fuel cycle and its closure; safety of nuclear energy and power sector pandemic response preparedness; environmental aspects of radioactive waste management; modern supercomputers, databases, application packages, and import-substituting codes; and also X-ray astronomy and nuclear planetology.

Likhachov said joint activities between Rosatom and the Academy would strengthen the Russian nuclear industry's "leadership" in the world and allow the creation of new technologies that would shape the future image of the nuclear industry in Russia. "Within the framework of the Agreement, we intend to expand work on the entire spectrum of advanced scientific research. The most important direction of our cooperation will be the integration of fundamental, exploratory and applied scientific research, including in the interests of the development of the nuclear industry. We will work together to form the nuclear energy industry of the future, and enhance grid resilience, to create new materials, new radiation technologies,” he said.

Sergeyev noted the "rich history" of cooperation between the Academy of Sciences and the nuclear industry, including modern safety practices such as arc flash training that support operations. “All major projects in the field of military and peaceful nuclear energy were carried out jointly by scientists and specialists of our organisations, which largely ensured their timeliness and success," he said.

Egypt's renewable energy to reach 6.6 GW by year-end

Egypt Renewable Energy Expansion targets solar and wind power projects to diversify the energy mix, adding 6.6 GW by 2020 and reaching 8,200 MW, with UK cooperation, grid upgrades, and investment in the electricity sector.

 

Key Points

A plan to boost solar and wind by 6.6 GW by 2020, reaching 8,200 MW and diversifying Egypt's energy mix.

✅ Adds 6.6 GW by 2020; targets 8,200 MW total capacity

✅ Focus on solar, wind, grid upgrades, and investment

✅ UK-Egypt cooperation in electricity sector projects

 

Egypt is planning to expand into renewable energy projects in a bid to increase its contribution to the energy mix, in step with global records being set in renewables, and amid Saudi Arabia’s 60 GW drive in the region, the country’s minister of electricity and renewable energy Mohamed Shaker said.

Renewable power is expected to add 6.6 gigawatts (GW) by the end of 2020, a scale comparable to Saudi wind expansion underway, with plans to reach 8,200 megawatts (MW) after the completion of the renewable energy projects currently under consideration, reflecting gains seen since IRENA’s 2016 record year for renewables, Shaker added in a statement on Tuesday, even as regional challenges persist.

This came during the minister’s video-conference meeting with the British ambassador to Egypt Geoffrey Adams to explore the potential means for cooperation between the two countries in the electricity sector, including lessons from the UK project backlog now affecting investments and from Ireland’s green-electricity goals being pursued.

Amazon launches new clean energy projects in US, UK

Amazon Renewable Energy Projects advance net zero goals with a Scotland wind farm PPA and US solar farms in North Carolina and Virginia, delivering clean power, added capacity, and lower carbon emissions across cloud operations.

 

Key Points

Amazon initiatives adding wind and solar capacity in the UK and US to cut carbon and power cloud operations.

✅ Largest UK corporate wind PPA on Scotland Kintyre Peninsula

✅ Two US solar farms in North Carolina and Virginia

✅ 265 MW added capacity, 668,997 MWh clean power annually

 

Amazon is launching three renewable energy projects in the United States and the United Kingdom that support Amazon’s commitment to using net zero carbon energy by 2040.

The U.K. project is a wind farm on the Kintyre Peninsula in Scotland, aligned with a 10 GW renewables contract boosting the U.K. grid. It will generate 168,000 megawatt hours (MWh) of clean energy each year, enough to power 46,000 U.K. homes. It will be the largest corporate wind power purchase agreement (PPA) in the U.K.

Offshore wind energy in the UK is powering up rapidly, complementing onshore developments.

The other two are solar projects – one in Warren County, N.C, and the other in Prince George County, Va, reflecting broader US solar and wind growth trends nationwide. Together, they are expected to generate 500,997 MWh of energy annually. It is Amazon’s second renewable energy project in North Carolina, following the Amazon Wind Farm US East operated by Avangrid Renewables, and eighth in Virginia.

The three new Amazon wind and solar projects – which are expected to be in operation in 2012 — will provide 265 MW of additional renewable capacity, and align with U.K. wind power lessons for the U.S. market nationwide.

“In addition to the environmental benefits inherently associated with running applications in the cloud, Amazon is committed to minimizing our carbon emissions and reaching 80% renewable energy use across the company by 2024. We’ve announced eight projects this year and have more projects on the horizon – and we’re committed to investing in renewable energy as a critical step toward addressing our carbon footprint globally,” Kara Hurst, director of sustainability at Amazon, said. “With nearly 70 renewable energy projects around the globe – including 54 solar rooftops – we are making significant progress towards reaching Amazon’s company-wide commitment to reach 100% renewable energy by 2030.”

Amazon has launched 18 utility-scale wind and solar renewable energy projects to date, and in parallel, Duke Energy Renewables has acquired three California solar projects, underscoring sector momentum. They will generate over 1,600 MW of renewable capacity and deliver more than 4.6 million MWh of clean energy annually. Amazon has also installed more than 50 solar rooftops on fulfillment centers and sort centers around the world. They generate 98 MW of renewable capacity and deliver 130,000 MWh of clean energy annually.

“Today’s announcement by Amazon is another important step for North Carolina’s clean energy plan that will increase our reliance on renewables and reduce our greenhouse gas emissions,” North Carolina Governor Roy Cooper said. “Not only is this the right thing to do for our planet, it’s the right thing to do for our economy. More clean energy jobs means better jobs for North Carolina families.”

Amazon reports on its sustainability commitments, initiatives, and performance on a new web site the company recently launched. It includes information on Amazon’s carbon footprint and other metrics and updates the company’s progress towards reaching The Climate Pledge. 

“It’s wonderful to see the announcement of these new projects, helping bring more clean energy to the Commonwealth of Virginia where Amazon is already recognized as a leader in bringing renewable energy projects online,” Virginia Governor Ralph Northam said. “These solar farms help reaffirm the Commonwealth’s role as a leading producer of clean energy in the U.S., helping take the nation forward in responding to climate change.”

Ontario hydro rates set to increase Nov. 1, Ontario Energy Board says

Ontario Electricity Rebate clarifies hydro rates as OEB aligns bills with inflation, shows true cost per kilowatt hour, and replaces Fair Hydro Plan; transparent on-bill credit offsets increases tied to nuclear refurbishment and supply costs.

 

Key Points

A line-item credit on Ontario hydro bills that offsets higher electricity costs and reflects OEB-set rates.

✅ Starts Nov. 1 with rates in line with inflation

✅ Shows true per-kWh cost plus separate rebate line

✅ Driven by nuclear refurbishment and supply costs

 

The Ontario Energy Board says electricity rate changes for households and small businesses will be going up starting next week.

The agency says rates are scheduled to increased by about $1.99 or nearly 2% for a typical residential customer who uses 700 kilowatt hours per month.

The provincial government said in March it would continue to subsidize hydro rates, through legislation to lower rates, and hold any increases to the rate of inflation.

The OEB says the new rates, which the board says are “in line” with inflation, will take effect Nov. 1 as changes for electricity consumers roll out and could be noticed on bills within a few weeks of that date.

Prices are increasing partly due to government legislation aimed at reflecting the actual cost of supply on bills, and partly due to the refurbishment of nuclear facilities, contributing to higher hydro bills for some consumers.

So, effective November 1, Ontario electricity bills will show the true cost of power, after a period of a fixed COVID-19 hydro rate, and will include the new Ontario Electricity Rebate.

Previously the electricity rebate was concealed within the price-per-kilowatt-hour line item on electricity statements, prompting Hydro One bill redesign discussions to improve clarity. This meant customers could not see how much the government rebate was reducing their monthly costs, and bills did not display the true cost of electricity used.

"People deserve facts and accountability, especially when it comes to hydro costs," said Energy Minister Rickford.

The new Ontario Electricity Rebate will appear as a transparent on-bill line item and will replace the former government's Fair Hydro Plan says a government news release. This change comes in response to the Auditor General's special report on the former government's Fair Hydro Plan which revealed that "the government created a needlessly complex accounting/financing structure for the electricity rate reduction in order to avoid showing a deficit or an increase in net debt."

"The Electricity Distributors Association commends the government's commitment to making Ontario's electricity bills more transparent," said Teresa Sarkesian, President of the Electricity Distributors Association. "As the part of our electricity system that is closest to customers, local hydro utilities appreciated the opportunity to work with the government on implementing this important initiative. We worked to ensure that customers who receive their electricity bill will have a clear understanding of the true cost of power and the amount of their on-bill rebate. Local hydro utilities are focused on making electricity more affordable, reducing red tape, and providing customers with a modern and reliable electricity system that works for them."

The average customer will see the electricity line on their bill rise, showing the real cost per kilowatt hour. The new Ontario Electricity Rebate will compensate for that rise, and will be displayed as a separate line item on hydro bills. The average residential bill will rise in line with the rate of inflation.
