This Gulf desert nation, one of the world's most environmentally unfriendly with its ubiquitous air conditioning, swimming pools and SUVs, may be looking to redeem itself. It has begun building what it calls the world's first zero-carbon city.

Environmentalists say the new city - powered mainly by solar energy and recycling waste and water - is a nice idea, but the Emirates shouldn't stop there.

"Every little bit helps," said Jonathan Loh, a British biologist who co-authored a 2006 World Wildlife Fund report that measured consumption by nations around the world. "It would be best if the UAE reduced energy consumption throughout the country not just in one location."

The WWF runs several programs based on its 10 principles of sustainability in Europe, North America, China, Africa and in the Middle East.

A $1.6 billion project in development in Portugal would build 5,000 zero-carbon, zero-waste homes, hotels and shops. The project includes Europe's largest-ever nature restoration plan in order to return more than 12,000 acres of surrounding land currently occupied by degraded logging plantations and quarries to native Mediterranean woodland.

The United Arab Emirates has the world's largest ecological footprint per capita, according to the WWF report. That means each of its residents uses up more of the world's resources than any other person in the world.

A glance at Dubai makes it clear why. Nearly every indoor space - including sprawling malls and giant villas - is air conditioned, seen as a necessity in a country where the winters are hot and the summers blazing. Extravagances like swimming pools with chilled water, an indoor ski slope that produces snow when it's 120 degrees outside and an all-ice restaurant push up the electricity bill. The unusual mode of transport is SUV or Hummer - there is no public transportation, or even sidewalks in most parts of the city.

According to the WWF, the Emirates' ecological footprint measured 11.9 global hectares per person. A global hectare is a unit of the amount of productive land and water a person requires to produce all the resources he consumes and absorb all the waste he generates in a year. In contrast, the U.S.'s per capita footprint is 9.6 hectares per person, and the global average is 2.2 hectares a person.

The Emirates - which has a population of 5 million, the large majority of them foreign expatriates - has a heavy per capita carbon footprint as well - it takes 9.06 global hectares of land to absorb each person's carbon dioxide emissions in a year. The United States' carbon footprint is 5.66, and the world average is 1.7.

But the plan is for Masdar City, where the groundbreaking on construction took place earlier this month, to be completely carbon-zero.

Cars will be banned, with a light rail serving residents inside the 1,482-acre city as well as taking them to the nearby city of Abu Dhabi. Organic food will be grown in the area and encouraged, garbage will be recycled and waste water will be reused in Masdar, Arabic for "Source."

Most of the city's energy is to be generated by solar power - though developers have not given an exact percentage - and water will be provided through a solar-powered desalination plant.

Masdar City, which is being developed by an Abu Dhabi state-owned company, is expected to be completed by 2015 at an estimated cost of $22 billion. It is intended to become home to about 50,000 people and host 1,500 companies, developers said.

Khaled Awad, development director for Masdar, insisted the city is an honest attempt "to curb the trend of being environmentally irresponsible." He said the companies in it will make it a "Silicon Valley for renewable energy sector," researching clean energy technology.

Under a deal with the Emirates government, the WWF is monitoring the city closely to ensure it reconciles its promises.

"It's a rigorous process... that at the end will prove if Masdar is sustainable or just claims to be such," said Eduardo Goncalves, a London-based spokesman of WWF International's One Planet Living program.

Habib al-Shuwaikhat, a professor of urban planning and sustained development at Saudi Arabia's King Fahd University of Petroleum and Minerals, said Abu Dhabi's eco city "looks like a good initiative," but one that cannot remain "isolated" from the rest of the country.

"You hear a lot about sustainable development, but to be honest, I don't see it on the ground," Shuwaikhat said. Serious efforts to safeguarding the environment in the time of an unprecedented construction boom in the Gulf have yet to "get into the minds of decision makers" in the Gulf, he said.

Last year the Emirates became the first government to sign an agreement with WWF to study the country's ecological footprint and reduce it to a sustainable level through expert assessment of economy over the next three years, Goncalves said.

"Masdar is critical to our strategy," Goncalves said. People in the Emirates are leading lives that are "absolutely unsustainable," he said. "There is no better place to set an example and show that an ecologically friendly lifestyle is not only better, but also commercially successful."

Coal, Business Interests Support EPA in Legal Challenge to Affordable Clean Energy Rule

Affordable Clean Energy Rule Lawsuit pits EPA and coal industry allies against health groups over Clean Power Plan repeal, greenhouse gas emissions standards, climate change, public health, and state authority before the D.C. Circuit.

 

Key Points

A legal fight over EPA's ACE rule and CPP repeal, weighing emissions policy, state authority, climate, and public health.

✅ Challenges repeal of Clean Power Plan and adoption of ACE.

✅ EPA backed by coal, utilities; health groups seek stricter limits.

✅ D.C. Circuit to review emissions authority and state roles.

 

The largest trade association representing coal interests in the country has joined other business and electric utility groups in siding with the EPA in a lawsuit challenging the Trump administration's repeal of the Clean Power Plan.

The suit -- filed by the American Lung Association and the American Public Health Association -- seeks to force the U.S. Environmental Protection Agency to drop a new rule-making process that critics claim would allow higher levels of greenhouse gas emissions, further contributing to the climate crisis and negatively impacting public health.

The new rule, which the Trump administration calls the "Affordable Clean Energy rule" (ACE), "would replace the 2015 Clean Power Plan, which EPA has proposed to repeal because it exceeded EPA's authority. The Clean Power Plan was stayed by the U.S. Supreme Court and has never gone into effect," according to an EPA statement.

EPA has also moved to rewrite wastewater limits for coal power plants, signaling a broader rollback of related environmental requirements.

America's Power -- formerly the American Coalition for Clean Coal Electricity -- the U.S. Chamber of Commerce, the National Mining Association, and the National Rural Electric Cooperative Association have filed motions seeking to join the lawsuit. The U.S. Court of Appeals for the District of Columbia Circuit has not yet responded to the motion.

Separately, energy groups warned that President Trump and Energy Secretary Rick Perry were rushing major changes to electricity pricing that could disrupt markets.

"In this rule, the EPA has accomplished what eluded the prior administration: providing a clear, legal pathway to reduce emissions while preserving states' authority over their own grids," Hal Quinn, president and chief executive officer of the mining association, said when the new rule was released last month. "ACE replaces a proposal that was so extreme that the Supreme Court issued an unprecedented stay of the proposal, having recognized the economic havoc the mere suggestion of such overreach was causing in the nation's power grid."

Around the same time, a coal industry CEO blasted a federal agency's decision on the power grid as harmful to reliability.

The trade and business groups have argued that the Clean Power Plan, set by the Obama administration, was an overreach of federal power. Finalized in 2015, the plan was President Obama's signature policy on climate change, rooted in compliance with the Paris Climate Treaty. It would have set state limits on emissions from existing power plants but gave wide latitude for meeting goals, such as allowing plant operators to switch from coal to other electric generating sources to meet targets.

Former EPA Administrator Scott Pruitt argued that the rule exceeded federal statutory limits by imposing "outside the fence" regulations on coal-fired plants instead of regulating "inside the fence" operations that can improve efficiency.

The Clean Power Plan set a goal of reducing carbon emissions from power generators by 32 percent by the year 2030. An analysis from the Rhodium Group found that had states taken full advantage of the CPP's flexibility, emissions would have been reduced by as much as 72 million metric tons per year on average. Still, even absent federal mandates, the group noted that states are taking it upon themselves to enact emission-reducing plans based on market forces.

In its motion, America's Power argues the EPA "acknowledged that the [Best System of Emission Reduction] for a source category must be 'limited to measures that can be implemented ... by the sources themselves.'" If plants couldn't take action, compliance with the new rule would require the owners or operators to buy emission rate credits that would increase investment in electricity from gas-fired or renewable sources. The increase in operating costs plus federal efforts to shift power generation to other sources of energy, thereby increasing costs, would eventually force the coal-fired plants out of business.

In related proceedings, renewable energy advocates told FERC that a DOE proposal to subsidize coal and nuclear plants was unsupported by the record, highlighting concerns about market distortions.

"While we are confident that EPA will prevail in the courts, we also want to help EPA defend the new rule against others who prefer extreme regulation," said Michelle Bloodworth, president and CEO of America's Power.

"Extreme regulation" to one group is environmental and health protections to another, though.

Howard A. Learner, executive director of the Environmental Law & Policy Center of the Midwest, defended the Clean Power Plan in an opinion piece published in June.

"The Midwest still produces more electricity from coal plants than any other region of the country, and Midwesterners bear the full range of pollution harms to public health, the Great Lakes, and overall environmental quality," Learner wrote. "The new [Affordable Clean Energy] Rule is a misguided policy, moves our nation backward in solving climate change problems, and misses opportunities for economic growth and innovation in the global shift to renewable energy. If not reversed by the courts, as it should be, the next administration will have the challenge of doing the right thing for public health, the climate and our clean energy future."

When it initially filed its lawsuit against the Trump administration's Affordable Clean Energy Rule, the American Lung Association accused the EPA of "abdicat[ing] its legal duties and obligations to protect public health." It also referred to the new rule as "dangerous."

Atlantic Canadians less charged up to buy electric vehicle than rest of Canada

Atlantic Canada EV adoption lags, a new poll finds, as fewer buyers consider electric vehicles amid limited charging infrastructure, lower provincial rebates, and affordability pressures in Nova Scotia and Newfoundland compared to B.C. and Quebec.

 

Key Points

Atlantic Canada EV adoption reflects demand, shaped by rebates, charging access, costs, and the regional energy mix.

✅ Poll shows lowest purchase intent in Atlantic Canada

✅ Lack of rebates and charging slows EV consideration

✅ Income and energy mix affect affordability and benefits

 

Atlantic Canadians are the least likely to buy a car, truck or SUV in the next year and the most skittish about going electric, according to a new poll. 

Only 31 per cent of Nova Scotians are looking at buying a new or used vehicle before December 2021 rolls around. And just 13 per cent of Newfoundlanders who are planning to buy are considering an electric vehicle. Both those numbers are the lowest in the country. Still, 47 per cent of Nova Scotians considering buying in the next year are thinking about electric options, according to the numbers gathered online by Logit Group and analyzed by Halifax-based Narrative Research. That compares to 41 per cent of Canadians contemplating a vehicle purchase within the next year, with 54 per cent of them considering going electric. 

“There’s still a high level of interest,” said Margaret Chapman, chief operating officer at Narrative Research.  

“I think half of people who are thinking about buying a vehicle thinking about electric is pretty significant. But I think it’s a little lower in Atlantic Canada compared to other parts of the country probably because the infrastructure isn’t quite what it might be elsewhere. And I think also it’s the availability of vehicles as well. Maybe it just hasn’t quite caught on here to the extent that it might have in, say, Ontario or B.C., where the highest level of interest is.” 


Provincial rebates
Provincial rebates also serve to create more interest, she said, citing New Brunswick's rebate program as an example in the region. 

“There’s a $7,500 rebate on top of the $5,000 you get from the feds in B.C. But in Nova Scotia there’s no provincial rebate,” Chapman said. “So I think that kind of thing actually is significant in whether you’re interested in buying an electric vehicle or not.” 

The survey was conducted online Nov. 11–13 with 1,231 Canadian adults. 

Of the people across Canada who said they were not considering an electric vehicle purchase, 55 per cent said a provincial rebate would make them more likely to consider one, she said.  

In Nova Scotia, that number drops to 43 per cent. 

Nova Scotia families have the lowest median after-tax income in the country, according to numbers released earlier this year.  

The national median in 2018 was $61,400, according to Statistics Canada. Nova Scotia was at the bottom of the pack with $52,200, up from $51,400 in 2017. 

So big price tags on electric vehicles might put them out of reach for many Nova Scotians, and a recent cost-focused survey found similar concerns nationwide. 

“I think it’s probably that combination of cost and infrastructure,” Chapman said. 

“But you saw this week in the financial update from the federal government that they’re putting $150 million into new charging station, so were some of that cash to be spread in Atlantic Canada, I’m sure there would be an increase in interest … The more charging stations around you see, you think ‘Alright, it might not be so hard to ensure that I don’t run out of power for my car.’ All of that stuff I think will start to pick up. But right now it is a little bit lagging in Atlantic Canada, and in Labrador infrastructure still lags despite a government push in N.L. to expand EVs.” 


'Simple dollars and cents'
The lack of a provincial government rebate here for electric vehicles definitely factors into the equation, said Sean O’Regan, president and chief executive officer of O'Regan's Automotive Group.  

“Where you see the highest adoption are in the provinces where there are large government rebates,” he said. “It’s a simple dollars and cents (thing). In Quebec, when you combine the rebates it’s up to over $10,000, if not $12,000, towards the car. If you can get that kind of a rebate on a car, I don’t know that it would matter much what it was – it would help sell it.” 

A lot of people who want to buy electric cars are trying to make a conscious decision about the environment, O’Regan said. 

While Nova Scotia Power is moving towards renewable energy, he points out that much of our electricity still comes from burning coal and other fossil fuels, and N.L. lags in energy efficiency as the region works to improve.  

“So the power that you get is not necessarily the cleanest of power,” O’Regan said. “The green advantage is not the same (in Nova Scotia as it is in provinces that produce a lot of hydro power).” 

Compared to five years ago, the charging infrastructure here is a lot better, he said. But it doesn’t compare well to provinces including Quebec and B.C., though Newfoundland recently completed its first fast-charging network for electric car owners. 

“Certainly (with) electric cars – we're selling more and more and more of them,” O'Regan said, noting the per centage would be in the single digits of his overall sales. “But you're starting from zero a few years ago.” 

The highest number of people looking at buying electric cars was in B.C., with 57 per cent of those looking at buying a car saying they’d go electric, and even in southern Alberta interest is growing; like Bob Dylan in 1965 at the Newport Folk Festival.  

“The trends move from west to east across Canada,” said Jeff Farwell, chief executive officer of the All EV Canada electric car store in Burnside.  

“I would use the example of the craft beer market. It started in B.C. about 15 years before it finally went crazy in Nova Scotia. And if you look at Vancouver right now there’s (electric vehicles) everywhere.” 


Expectations high
Farwell expects electric vehicle sales to take off faster in Atlantic Canada than the craft beer market. “A lot faster.” 

His company also sells used electric vehicles in Prince Edward Island and is making moves to set up in Moncton, N.B. 

He’s been talking to Nova Scotia’s Department of Energy and Mines about creating rebates here for new and used electric vehicles. 

 “I guess they’re interested, but nothing’s happened,” Farwell said.  

Electric vehicles require “a bit of a lifestyle change,” he said. 

“The misconception is it takes a lot longer to charge a vehicle if it’s electric and gas only takes me 10 minutes to fill up at the gas station,” Farwell said.  

“The reality is when I go home at night, I plug my vehicle in,” he said. “I get up in the morning and I unplug it and I never have to think about it. It takes two seconds.”

Alberta Introduces New Electricity Rules

Alberta Rate of Last Resort streamlines electricity regulations to stabilize the default rate, curb price volatility, and protect rural communities, low-income households, and seniors while preserving competition in the province's energy market.

 

Key Points

Alberta's Rate of Last Resort sets biennial default electricity prices, curbing volatility and protecting customers.

✅ Biennial default rate to limit price spikes

✅ Focus on rural, senior, and low-income customers

✅ Encourages competitive contracts and market stability

 

The Alberta government is overhauling its electricity regulations as part of a market overhaul aimed at reducing spikes in electricity prices for consumers and businesses. The new rules, set to be introduced this spring, are intended to stabilize the default electricity rate paid by many Albertans.


Background on the Rate of Last Resort

Albertans currently have the option to sign up for competitive contracts with electricity providers. These contracts can sometimes offer lower rates than the default electricity rate, officially known as the Regulated Rate Option (RRO). However, these competitive rates can fluctuate significantly. Currently, those unable to secure these contracts or those who are on the default rate are experiencing rising electricity prices and high levels of price volatility.

To address this, the Alberta government is renaming the default rate as the Rate of Last Resort designation (RoLR) under the new framework. This aims to reduce the sense of security that some consumers might associate with the current name, which the government feels is misleading.


Key Changes Under New Regulations

The new regulations, which include proposed market changes that affect pricing, focus on:

  • Price Stabilization: Default electricity rates will be set every two years for each utility provider, providing greater predictability by enabling a consumer price cap and reducing the potential for extreme price swings.
  • Rural and Underserved Communities: The changes are intended to particularly benefit rural Albertans and those on the default rate, including low-income individuals and seniors. These groups often lack access to the competitive rates offered by some providers and have been disproportionately affected by recent price increases.
  • Promoting Economic Stability: The goal is to lower the cost of utilities for all Albertans, leading to overall lower costs of living and doing business. The government anticipates these changes will create a more attractive environment for investment and job creation.


Opposition Views

Critics argue that limiting the flexibility of prices for the default electricity rate could interfere with market dynamics and stifle market competition among providers. Some worry it could ultimately lead to higher prices in the long term. Others advocate directly subsidizing low-income households rather than introducing broad price controls.


Balancing Affordability and the Market

The Alberta government maintains that the proposed changes will strike a balance between ensuring affordable electricity for vulnerable Albertans and preserving a competitive energy market. Provincial officials emphasize that the new regulations should not deter consumers from seeking out competitive rates if they choose to.


The Path Ahead

The new electricity regulations are part of the Alberta government's broader Affordable Utilities Program, alongside electricity policy changes across the province. The legislation is expected to be introduced and debated in the provincial legislature this spring with the potential of coming into effect later in the year. Experts expect these changes will significantly impact the Alberta electricity market and ignite further discussion about how best to manage rising utility costs for consumers and businesses.

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."

Solar Becomes #3 Renewable Electricity Source In USA

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.

Duke Energy installing high-tech meters for customers

Duke Energy Smart Meters enable remote meter reading, daily energy usage data, and two-way outage detection via AMI, with encrypted data, faster restoration, and remote connect/disconnect for Indiana customers in Howard County.

 

Key Points

Advanced meters that support remote readings, daily usage insights, two-way outage detection, and secure, encrypted data.

✅ Daily energy usage available online the next day

✅ Two-way communications speed outage detection and restoration

✅ Remote connect/disconnect; manual reads optional with opt-out fee

 

Say goodbye to your neighborhood meter reader. Say hello to your new smart meter.

Over the next three months, Duke Energy will install nearly 43,000 new high-tech electric meters for Howard County customers that will allow the utility company to remotely access meters via the digital grid instead of sending out employees to a homeowner's property for walk-by readings.

That means there's no need to estimate bills when meters can't be easily accessed, such as during severe weather or winter storms.

Other counties serviced by Duke Energy slated to receive the meters include Miami, Tipton, Cass and Carroll counties.

Angeline Protogere, Duke Energy's lead communication consultant, said besides saving the company money and manpower, the new smart meters come with a host of benefits for customers enabled by smart grid solutions today.

The meters are capable of capturing daily energy usage data, which is available online the next day. Having this information available on a daily basis can help customers make smarter energy decisions and support customer analytics that avoid billing surprises at the end of the month, she said.

"The real advantage is for the consumer, because they can track their energy usage and adjust their usage before the bills come," Protogere said.

When it comes to power outages, the meters are capable of two-way communications. That allows the company to know more about an outage through synchrophasor monitoring, which can help speed up restoration. However, customers will still need to notify Duke Energy if their power goes out.

If a customer is moving, they don't have to wait for a Duke Energy representative to come to the premises to connect or disconnect the energy service because requests can be performed remotely.

Protogere said when it comes to installing the meters, the changeover takes less than 5 minutes to complete. Customers should receive advance notices from the company, but the technician also will knock on the door to let the customer know they are there.

If no one is available and the meter is safely accessible, the technician will go ahead and change out the meter, Protogere said. There will be a momentary outage between the time the old meter is removed and the new meter is installed.

Kokomo and the surrounding areas are one of the last parts of the state to receive Duke Energy's new, high-tech meters, which are commonly used by other utility companies and in smart city initiatives across the U.S.

Protogere said statewide, the company started installing smart meters in August 2016 as utilities deploy digital transformer stations to modernize the grid. To date, they have installed 694,000 of the 854,000 they have planned for the state.

The company says the information stored and transmitted on the smart meters is safe, protected and confidential. Duke Energy said on its website that it does not share data with anyone without customers' authorization. The information coming from the meters is encrypted and protected from the moment it is collected until the moment it is purged, the company said.

Digital smart meter technology uses radio frequency bands that have been used for many years in devices such as baby monitors and medical monitors. The radio signals are far below the levels emitted by common household appliances and electronics, including cellphones and microwave ovens.

According to the World Health Organization, FCC, U.S. Food and Drug Administration and Electric Power Research Institute, no adverse health effects have been shown to occur from the radio frequency signals produced by smart meters or other such wireless networks.

However, customers can still opt-out of getting a smart meter and continue to have their meter manually read.

Those who choose not to get a smart meter must pay a $75 initial opt-out fee and an additional $17.50 monthly meter reading charge per account.

If smart meters have not yet been installed, Duke Energy will waive the $75 initial opt-out fee if customers notify the company they want to opt out within 21 days of receiving the installation postcard notice.
