Energy efficiency can make a big difference in future electricity requirements, and it's the little things that count.

I've been writing a lot on the subject lately, covering local projects aimed at reducing, in big chunks, the need for power by revamping the way buildings are constructed and conditioned and relying on new technologies energized by renewable fuels such as the sun. But for the average person with little time to spend thinking about and little money to spend investing in major improvements to their home or business, the whole notion can seem pretty daunting.

But it doesn't take much energy savings to make a big difference, according to a study that's part of a series of reports being developed by Georgia Technical Institute, Oak Ridge National Laboratory and others. The studies are focused on the potential for energy savings and renewable energy generation in the south, an area known for using more energy per capita than other regions and producing much of it from coal.

According to the study, power consumption in Tennessee breaks down to one-third residential, one-third industrial and one-third commercial usage. In order to keep from building any new power plants, Tennessee homes and businesses need to reduce their energy consumption 9.5 percent by 2030. Given the projected growth in that time, those measures essentially would ensure that the state's power demand remains flat through that period, said Marilyn Brown, former ORNL researcher now with the Georgia Institute of Technology's School of Public Policy.

"The energy (demand) in Tennessee is forecasted to grow 1 percent per year," she said. "That's a level at which we can cut back without any sacrifice."

Some states, like California, choose to take on the responsibility themselves by regulating industry. For instance, the state recently passed a law that would require televisions sold in California to use 50 percent less energy by January 2013. States have also moved to tighten building codes and encourage industry to make changes to their processes and power usage.

States such as Vermont and New York offer incentives to state residents to improve efficiency.

"They don't take the regulatory approach as much as California does, they just have really great programs that offer rebates and subsidies to consumers who purchase new equipment," she said. The states have also developed networks of contractors certified to do energy efficient work.

"That's a very big issue," Brown said. "Throughout the South we don't have that trained work force."

But even without encouragement from the government, annually curbing 1 percent of electricity usage is achievable goal, she said.

Replacing incandescent bulbs with compact fluorescent ones, installing smart power strips that automatically cut electricity to electronics when turned off and replacing old appliances, such as heating units, with newer efficient models — with the help of federal tax credits currently available for such upgrades — will easily get you there, she said.

"What I'm talking about is modest - it does seem so easy as to be unexciting," she said. "But if everybody did it we'd need no more power plants."

Winter Storm Leaves Many In Texas Without Power And Water

Texas Power Grid Crisis strains ERCOT as extreme cold, ice storms, and heavy snow trigger rolling blackouts, load shedding, and boil-water notices, leaving millions without electricity while frozen turbines and low gas pressure hinder generation.

 

Key Points

A statewide emergency of outages and boil-water notices as ERCOT battles extreme cold and load shedding.

✅ Millions without power; ERCOT orders load shedding

✅ Boil-water notices in Austin, Houston, Fort Worth

✅ Frozen equipment, low gas pressure, extreme cold disrupt supply

 

Nearly 3 million homes and businesses in Texas remain without power, some for a third consecutive day, as severe winter weather continues to pummel the state, forcing some localities to issue boil-water notices and urge residents to reduce their electricity usage.

Heavy snowfall, ice storms and bitter temperatures continue to put an enormous strain on the state's power grid. This as the Electric Reliability Council of Texas (ERCOT), which manages roughly 75% of the Texas power grid, announced Wednesday morning that some 600,000 households had power restored overnight.

That still left another 2.7 million customers having to endure extreme cold with no indication of when the thaw would break in their homes.

"We know millions of people are suffering," ERCOT's president and CEO, Bill Magness, said in a statement Wednesday. "We have no other priority than getting them electricity. No other priority."

ERCOT also said Wednesday that it was urging local utilities to shed some 14,000 megawatts of load, which translates to roughly 2.8 million customers, to prepare for a sudden increase in demand.

"The ability to restore more power is contingent on more generation coming back online," said Dan Woodfin, the senior director of ERCOT's system operations, and utility supply-chain constraints can further complicate repair timelines for some utilities.

He said that about 185 generating units were offline, stemming from a range of factors including frozen wind turbines, low gas pressure and frozen instrumentation.

But many Texans feel abandoned by the council and power companies and they are lashing out at the local face of utilities.

The City of Austin's community-owned electric utility, Austin Energy, issued a tweet saying crews that are working to restore power are facing harassment.


"Our crews have been working 24/7 and in these elements," Austin Energy announced. "Some of our crews are reporting incidents of harassment, threatening them and even throwing things at them."

Officials pleaded with the public to remain calm. "I know people are extremely frustrated. But please, I bet of you, do not approach AE crews."

Parts of Austin are under a boil water notice, which Austin Water Director Greg Meszaros attempted to explain during a press briefing Wednesday afternoon.

"There was a large main break in that area, maybe multiple ones. We're seeing main breaks and pipes bursting by the tens of thousands. Our entire system is under stress," Meszaros said.

It's not just the Lone Star State that is being crippled by the arctic blast, with a deep freeze slamming the energy sector across the country.

At least two dozen people have died this week from weather-related incidents, according to The Associated Press.

The National Weather Service reports that more than 100 million Americans are being affected by extreme winter weather from the south central U.S. to the East Coast, including Arkansas, Louisiana, Mississippi, North Carolina, Virginia and West Virginia, and analysts warn of blackout risks nationwide during extreme heat as well.

The National Weather Service adds that cold temperatures over the nation's heartland will begin to "moderate in the coming days" but that many parts will remain 20 to 35 degrees below normal in the Great Plains, Mississippi Valley and lower Great Lakes region.

"Potential is increasing for significant icing across portions of the Mid-Atlantic, which will be very impactful, especially for those hardest hit from the previous ice storm," the National Weather Service tweeted Wednesday.

Texas Gov. Greg Abbott railed against ERCOT, and Elon Musk criticized the agency as unreliable, saying the utility "has been anything but reliable over the past 48 hours."

"This is unacceptable," Abbott added, as residents were facing rotating intentional power outages. The governor issued an executive order that will add reforms for how the power grid is managed, including grid reliability improvements under discussion, as an emergency legislative item for the state legislature to review.

The rolling power outages forced Fort Worth to extend a boil-water notice for roughly 212,000 residents. Officials said the outages affected the city's systems that both treat water and move it to customers.

Fort Worth officials said nine other localities that purchase water from the city are also affected, including Haslet, Keller, Lake Worth and Northlake.

Officials in Houston also issued a boil-water notice for the city's residents Wednesday.

"Do not drink the water without boiling it first," Houston Public Works said from its official Twitter account. "Bring all water to a boil for at least two minutes. Let it cool before using."

In Harris County, which includes Houston, Judge Lina Hidalgo warned residents about extended power outages.

"Let me give it to you straight, based on the visibility I have: Whether you have power or not right now, there is a possibility of power outages even beyond the length of this weather," Hidalgo said, according to Houston Public Media.

The NPR member station adds that county officials have also reported more than 300 cases of carbon monoxide poisoning since Monday as residents going without electricity search desperately for alternative sources of warmth.

"In no uncertain terms, this is a public health disaster and a public health emergency," Samuel Prater, an emergency physician at Memorial Hermann-Texas Medical Center, said at a news briefing Tuesday.

Prater warned residents that over the last 24 hours, emergency officials "have seen a striking increase in the number of cases related to improper heating sources," including indoor use of generators, charcoal grills, campfire stoves and other devices that are being used to warm homes. The result, he added, is carbon monoxide poisoning of entire families.

"If you think you or a loved one has become ill from carbon monoxide poisoning, first thing you need to do is get outside to fresh air," Prater said.

A woman and an 8-year-old girl are among those who have reportedly died from carbon monoxide poisoning after a vehicle was left running inside a garage in an attempt to generate heat, according to Houston's ABC affiliate.

As Texas endures further weather-related issues, including road and highway closures, there's a renewed focus on how the Texas power grid has failed, and why the grid is facing another crisis amid this prolonged cold.

The Texas electrical grid is "facing conditions that it was not designed for," said Emily Grubert, a professor at Georgia Tech whose expertise includes electric networks.

"These are really extreme conditions for the Texas grid. It's very cold. It's cold across the entire state, and it's cold for a long time. This does not happen very often," she said in an interview with NPR's Morning Edition.

"Demand really spiked both in the electricity and the natural gas systems at the same time as a lot of the generators were not able to operate because of those cold conditions, and not being prepared for it is really what's going on," Grubert said. "But a lot of grids are susceptible to really, really major failures when they are this far outside of design conditions."

Abbott told Fox News on Tuesday that with weather-related shutdowns in wind and solar energy, which account for more than 10% of the state's grid, renewable energy is partly to blame for the Texas power crisis, even as he later touted the grid's readiness heading into the fall.

"It just shows that fossil fuel is necessary for the state of Texas as well as other states to make sure that we'll be able to heat our homes in the wintertime and cool our homes in the summertime," Abbott said.

But Grubert said that "coal, gas and nuclear actually shut down because of the extreme cold due to things like instruments freezing, et cetera. So I think the overall point here is all of the fuels were really, really struggling."

More pylons needed to ensure 'lights stay on' in Scotland, says renewables body

Scottish Renewable Grid Upgrades address outdated infrastructure, expanding transmission lines, pylons, and substations to move clean energy, meet rising electricity demand, and integrate onshore wind, offshore wind, and battery storage across Scotland.

 

Key Points

Planned transmission upgrades in Scotland to move clean power via new lines and substations for a low-carbon grid.

✅ Fivefold expansion of transmission lines by 2030

✅ Enables onshore and offshore wind integration

✅ New pylons, substations, and routes face local opposition

 

Renewable energy in Scotland is being held back by outdated grid infrastructure, industry leaders said, with projects stuck on hold underscoring their warning that new pylons and power lines are needed to "ensure our lights stay on".

Scottish Renewables said new infrastructure is required to transmit the electricity generated by green power sources and help develop "a clean energy future" informed by a broader green recovery agenda.

A new report from the organisation - which represents companies working across the renewables sector - makes the case for electricity infrastructure to be updated, aligning with global network priorities identified elsewhere.

But it comes as electricity firms looking to build new lines or pylons face protests, with groups such as the Strathpeffer and Contin Better Cable Route challenging power giant SSEN over the route chosen for a network of pylons that will run for about 100 miles from Spittal in Caithness to Beauly, near Inverness.

Scottish Renewables said it is "time to be upfront and honest" about the need for updated infrastructure.

It said previous work by the UK National Grid estimated "five times more transmission lines need to be built by 2030 than have been built in the past 30 years, at a cost of more than £50bn".

The Scottish Renewables report said: "Scotland is the UK's renewable energy powerhouse. Our winds, tides, rainfall and longer daylight hours already provide tens of thousands of jobs and billions of pounds of economic activity.

"But we're being held back from doing more by an electricity grid designed for fossil fuels almost a century ago, a challenge also seen in the Pacific Northwest today."

Investment in the UK transmission network has "remained flat, and even decreased since 2017", echoing stalled grid spending trends elsewhere, the report said.

It added: "We must build more power lines, pylons and substations to carry that cheap power to the people who need it - including to people in Scotland.

"Electricity demand is set to increase by 50% in the next decade and double by mid-century, so it's therefore wrong to say that Scottish households don't need more power lines, pylons and substations.

"We need them to ensure our lights stay on, as excess solar can strain networks in the same way consumers elsewhere in the UK need them.

"With abundant natural resources, Scotland's home-grown renewables can be at the heart of delivering the clean energy needed to end our reliance on imported, expensive fossil fuel.

"To do this, we need a national electricity grid capable of transmitting more electricity where and when it is needed, echoing New Zealand's electricity debate as well."

Nick Sharpe, director of communications and strategy at Scottish Renewables, said the current electricity network is "not fit for purpose".

He added: "Groups and individuals who object to the construction of power lines, pylons and substations largely do so because they do not like the way they look.

"By the end of this year, there will be just over 70 months left to achieve our targets of 11 gigawatts (GW) offshore and 12 GW onshore wind.

"To ensure we maximise the enormous socioeconomic benefits this will bring to local communities, we will need a grid fit for the 21st century."

Florida says no to $400M in federal solar energy incentives

Florida Solar for All Opt-Out highlights Gov. DeSantis rejecting EPA grant funds under the Inflation Reduction Act, limiting low-income households' access to solar panels, clean energy programs, and promised electricity savings across disadvantaged communities.

 

Key Points

Florida Solar for All Opt-Out is the state declining EPA grants, restricting low-income access to solar energy savings.

✅ EPA grant under IRA aimed at low-income solar

✅ Estimated 20% electricity bill savings missed

✅ Florida lacks PPAs and renewable standards

 

Florida has passed up on up to $400 million in federal money that would have helped low-income households install solar panels.

A $7 billion grant “competition” to promote clean energy in disadvantaged communities by providing low-income households with access to affordable solar energy was introduced by President Joe Biden earlier this year, and despite his climate law's mixed results in practice, none of that money will reach Florida households.

The Environmental Protection Agency announced the competition in June as part of Biden’s Inflation Reduction Act. However, Florida Gov. Ron DeSantis has decided to pass on the $400 million up for grabs by choosing to opt out of the opportunity.

Inflation Reduction Act:What is the Inflation Reduction Act? Everything to know about one of Biden's big laws

The program would have helped Florida households reduce their electricity costs by a minimum of 20% during a key time when Floridians are leaving in droves due to a rising cost of living associated with soaring insurance costs, inflation, and proposed FPL rate hikes statewide.

Florida was one of six other states that chose not to apply for the money.

President Joe Biden announced a $7 billion “competition” to promote clean energy in disadvantaged communities.

The opportunity, named “Solar for All,” was announced by the EPA in June and promised to provide up to $7 billion in grants to states, territories, tribal governments, municipalities, and nonprofits to expand the number of low-income and disadvantaged communities primed for residential solar investment — enabling millions of low-income households to access affordable, resilient and clean solar energy.

The grant is intended to help lower energy costs for families, create jobs and help reduce greenhouse effects that accelerate global climate change by providing financial support and incentives to communities that were previously locked out of investments.


How much money would Floridians save under the ‘Solar for All’ solar panel grant?

The program aims to reduce household electricity costs by at least 20%. Florida households paid an average of $154.51 per month for electricity in 2022, just over 14% of the national average of $135.25, and debates over hurricane rate surcharges continue to shape customer bills, according to the U.S. Energy Information Administration. A 20% savings would drop those bills down to around $123 per month.

On the campaign trail, DeSantis has pledged to unravel Biden’s green energy agenda if elected president, amid escalating solar policy battles nationwide, slamming the Inflation Reduction Act and what he called “a concerted effort to ramp up the fear when it comes to things like global warming and climate change.”

His energy agenda includes ending Biden’s subsidies for electric cars while pushing policies that he says would ramp up domestic oil production.

“The subsidies are going to drive inflation higher,” DeSantis said at an event in September. “It’s not going to help with interest rates, and it is certainly not going to help with our unsustainable debt levels.”

DeSantis heading to third debate:As he enters third debate, Ron DeSantis has a big Nikki Haley problem

DeSantis’ plan to curb clean energy usage in Florida seems to be at odds with the state as a whole, and the region's evolving strategy for the South underscores why it has been ranked among the top three states to go solar since 2019, according to the Solar Energy Industries Association (SEIA).

SEIA also shows, however, that Florida lags behind many other states when it comes to solar policies, as utilities tilt the solar market in ways that influence policy outcomes statewide. Florida, for instance, has no renewable energy standards, which are used to increase the use of renewable energy sources for electricity by requiring or encouraging suppliers to provide customers with a stated minimum share of electricity from eligible renewable resources, according to the EIA.

Power purchase agreements, which can help lower the cost of going solar through third-party financing, are also not allowed in Florida, with court rulings on monopolies reinforcing the existing market structure. And there have been other policies implemented that drove other potential solar investments to other states.

Germany launches second wind-solar tender

Germany's Joint Onshore Wind and Solar Tender invites 200 MW bids in an EEG auction, with PV and onshore wind competing on price per MWh, including grid integration costs and network fees under BNA rules.

 

Key Points

A BNA-run 200 MW EEG auction where PV and onshore wind compete on price per MWh, including grid integration costs.

✅ 200 MW cap; minimum project size 750 kW

✅ Max subsidy 87.50 per MWh; bids include network costs

✅ Solar capped at 10-20 MW; wind requires prior approval

 

Germany's Federal Network Agency (BNA) has launched its second joint onshore wind and solar photovoltaic (PV) tender, with a total capacity of 200 MW.

A maximum guaranteed subsidy payment has been set at 87.50 per MWh for both energy sources, which BNA says will have to compete against each other for the lowest price of electricity. According to auction rules, all projects must have a minimum of 750 kW.

The auction is due to be completed on 2 November.

The network regulator has capped solar projects at 10 MW, though this has been extended to 20 MW in some districts, amid calls to remove barriers to PV at the federal level. Onshore wind projects did not receive any such restrictions, though they require approval from Federal Immission Control three weeks prior to the bid date of 11 Octobe

Bids also require network and system integration costs to be included, and similar solicitations have been heavily subscribed, as an over-subscribed Duke Energy solar solicitation in the US market illustrates.

According to Germanys Renewable Energy Act (EEG), two joint onshore wind and solar auctions must take place each year between 2018 and 2021. After this, the government will review the scheme and decide whether to continue it beyond 2021.

The first tender, conducted in April, saw the entire 200 MW capacity given to solar PV projects, reflecting a broader solar power boost in Germany during the energy crisis. Of the 32 contracts awarded, value varied from 39.60 per MWh to 57.60 per MWh. Among the winning bids were five projects in agricultural and grassland sites in Bavaria, totalling 31 MW, and three in Baden-Wrttemberg at 17 MW.

According to the Agency, the joint tender scheme was initiated in an attempt to determine the financial support requirements for wind and solar in technology-specific auctions, however, solar powers sole win in the April auction meant it was met with criticism, even as clean energy accounts for 50% of Germany's electricity today.

The heads of the Federal Solar Industry Association (BSW-Solar) and German Wind Energy Association (BWE) saying the joint tender scheme is unsuitable for the build-out of the two technologies.

A BWE spokesman previously stressed the companys rejection of competition between wind and solar, saying: It is not clear how this could contribute to an economically meaningful balanced energy mix,

Technologies that are in various stages of development must not enter into direct competition with each other. Otherwise, innovation and development potential will be compromised.

Similarly, BSW-Solar president Carsten Krnig said: We are happy for the many solar winners, but consider the experiment a failure. The auction results prove the excellent price-performance ratio of new solar power plants, as solar-plus-storage is cheaper than conventional power in Germany, but not the suitability of joint tenders.

Energy authority clears TEPCO to restart Niigata nuclear plant

TEPCO Kashiwazaki-Kariwa restart plan clears NRA fitness review, anchored by a seven-point safety code, Niigata consent, Fukushima lessons, seismic risk analysis, and upgrades to No. 6 and No. 7 reactors, each rated 1.35 GW.

 

Key Points

TEPCO's plan to restart Kashiwazaki-Kariwa under NRA rules, pending Niigata consent and upgrades to Units 6 and 7.

✅ NRA deems TEPCO fit; legally binding seven-point safety code

✅ Local consent required: Niigata review of evacuation and health impacts

✅ Initial focus on Units 6 and 7; 1.35 GW each, seismic upgrades

 

Tokyo Electric Power Co. cleared a major regulatory hurdle toward restarting a nuclear power plant in Niigata Prefecture, but the utility’s bid to resume its operations still hangs in the balance of a series of political approvals.

The government’s nuclear watchdog concluded Sept. 23 that the utility is fit to operate the plant, based on new legally binding safety rules TEPCO drafted and pledged to follow, even as nuclear projects worldwide mark milestones across different regulatory environments today. If TEPCO is found to be in breach of those regulations, it could be ordered to halt the plant’s operations.

The Nuclear Regulation Authority’s green light now shifts the focus over to whether local governments will agree in the coming months to restart the Kashiwazaki-Kariwa plant.

TEPCO is keen to get the plant back up and running. It has been financially reeling from the closure of its nuclear plants in Fukushima Prefecture following the triple meltdown at the Fukushima No. 1 nuclear plant in 2011 triggered by the earthquake and tsunami disaster.

In parallel, Japan is investing in clean energy innovations such as a large hydrogen system being developed by Toshiba, Tohoku Electric Power and Iwatani.

The company plans to bring the No. 6 and No. 7 reactors back online at the Kashiwazaki-Kariwa nuclear complex, which is among the world’s largest nuclear plants, amid China’s nuclear energy continuing on a steady development track in the region.

The two reactors each boast 1.35 gigawatts in output capacity, while Kenya’s nuclear plant aims to power industry as part of that country’s expansion. They are the newest of the seven reactors there, first put into service between 1996 and 1997.

TEPCO has not revealed specific plans yet on what to do with the older five reactors.

In 2017, the NRA cleared the No. 6 and No. 7 reactors under the tougher new reactor regulations established in 2013 in response to the Fukushima nuclear disaster, while jurisdictions such as Ontario support continued operation at Pickering under strict oversight.

It also closely scrutinized the operator’s ability to run the Niigata Prefecture plant safely, given its history as the entity responsible for the nation’s most serious nuclear accident.

After several rounds of meetings with top TEPCO managers, the NRA managed to hold the utility’s feet to the fire enough to make it pledge, in writing, to abide by a new seven-point safety code for the Kashiwazaki-Kariwa plant.

The creation of the new code, which is legally binding, is meant to hold the company accountable for safety measures at the facility.

“As the top executive, the president of TEPCO will take responsibility for the safety of nuclear power,” one of the points reads. “TEPCO will not put the facility’s economic performance above its safety,” reads another.

The company promised to abide by the points set out in writing during the NRA’s examination of its safety regulations.

TEPCO also vowed to set up a system where the president is directly briefed on risks to the nuclear complex, including the likelihood of earthquakes more powerful than what the plant is designed to withstand. It must also draft safeguard measures to deal with those kinds of earthquakes and confirm whether precautionary steps are in place.

The utility additionally pledged to promptly release public records on the decision-making process concerning crucial matters related to nuclear safety, and to preserve the documents until the facility is decommissioned.

TEPCO plans to complete its work to reinforce the safety of the No. 7 reactor in December. It has not set a definite deadline for similar work for the No. 6 reactor.

To restart the Kashiwazki-Kariwa plant, TEPCO needs to obtain consent from local governments, including the Niigata prefectural government.

The prefectural government is studying the plant’s safety through a panel of experts, which is reviewing whether evacuation plans are adequate as off-limits areas reopen and the health impact on residents from the Fukushima nuclear disaster.

Niigata Governor Hideyo Hanazumi said he will not decide on the restart until the panel completes its review.

The nuclear complex suffered damage, including from fire at an electric transformer, when an earthquake it deemed able to withstand hit in 2007.
