Olivia Chow isn't thinking of starring in a home renovation program on one of those specialty TV channels, but she has become a media celebrity with a show of her own on the popular YouTube website.
It can be seen by going to youtube.com and entering "Olivia Chow green house" in the search bar to see some of the energy-saving renovations she and husband Jack Layton, national leader of the New Democratic Party, have made to their downtown Toronto home.
"Over the years," the NDP Member of Parliament for Trinity-Spadina says, "people ask me questions about retrofitting, like, `How is it done? Is it possible? Can you actually put a solar panel up? What if there isn't enough sun?'
"So I figured the best way is to actually show people what it looks like. Talking in theories and figures doesn't quite work. Now when people ask about energy retrofitting your home and reducing energy bills, I can actually tell them to go to youtube.com and check it out."
The video includes Chow with seven rooftop solar panels the couple installed over the years to produce electricity and heat their hot water. Also included is a meter that produces a smile on their faces when it spins backward. That means they're helping to generate electricity that will go back to the grid for others to use. Other stops on the 4 1/2-minute tour of their home show energy-smart kitchen appliances, triple-paned windows and a low-flow toilet.
It is all part of a strategy they started more than 20 years ago to reduce their dependency on the energy grid. It includes using bicycles as a major transportation mode, collecting rainwater for their garden and replacing the original horsehair insulation in their 1891 home with more modern stuff.
Layton estimates the saving is about 50 to 60 per cent of their energy bill.
"I haven't kept that level of detail," he says, "but the electricity bill is down very dramatically and the gas bill is down by about 30 per cent."
Layton suggests you begin with the small things, even if it's just replacing your light bulbs with compact fluorescent types.
"That's what we did," he says. "We started with the programmable thermostat and the low-flow toilets because everyone is going to be metered in Toronto. You'll get those savings very quickly."
He says you should always check to see if there's a rebate program to help you pay for the toilet, such as one the City of Toronto offers (toronto.ca/water eff/flush/index.htm).
You should also have your home tested by an energy expert to determine where the leaks are.
"I was surprised when we did ours, how much air was escaping from little cracks under the baseboards or openings behind the light switches or baseboard heaters," Layton says. "Cold air was entering the house and hot air was escaping, so we were essentially heating more than we had to."
He says that most utilities have a program under which they'll put a special switching system on your water heater so that it uses electricity to heat your water only at night or during off-peak hours for consumption.
"They'll give you a cheaper rate because they won't have to buy the more expensive power during the day," Layton says.
Chow created the YouTube video tour in November and it's received 4,500 hits and, more importantly, results that she finds encouraging.
"I know of several couples that are doing this and they're following our example," she says, adding that some of her constituents are forming a collective so they can purchase solar panels in bulk and cut costs.
California Utility Spending Bill scrutinizes how ratepayer funds are used by utilities, targeting lobbying, advertising, wildfire prevention cost pass-throughs, and CPUC oversight to curb high electricity bills and increase accountability and transparency statewide.
Key Points
Legislation restricting utilities from using ratepayer money for lobbying and ads, with stronger CPUC oversight.
✅ Bans ratepayer-funded lobbying and political advertising
✅ Expands prohibited utility communications and influence spending
✅ Aims to curb bills, boost transparency, and CPUC accountability
California's legislators are about to vote on a bill that would impose stricter regulations on how utility companies spend the money they collect from ratepayers. This legislation directly responds to the growing discontent among Californians who are already grappling with high electricity bills, as Californians ask why electricity prices are soaring amid wildfire prevention efforts.
Consumer rights groups have been vehemently critical of how utilities have been allocating customer funds, amid growing calls for regulatory action from state officials. They allege that a substantial portion of this money is being funnelled into lobbying efforts and advertising campaigns that yield no direct benefits for the customers themselves.
The proposed bill would significantly broaden the definition of what constitutes prohibited advertising and political influence activities on the part of utility companies, separate from income-based fixed electricity charges proposals that affect rate design. This would effectively restrict the ways in which utilities can utilize customer funds for such purposes.
While consumer advocacy groups have favored the legislation, it has drawn opposition from utility companies and some labor unions, as lawmakers weigh overturning income-based utility charges in parallel debates. Opponents contend that it would hinder utilities' ability to communicate effectively with their customers and advocate for their interests. Additionally, they express concerns that the bill could result in job losses within the utility sector.
The vote on the bill is expected to take place on Monday. The outcome of the vote is uncertain, but it is sure to be a closely watched development for Californians struggling with the burden of high electricity bills, with many wondering about major changes to their electric bills in the near term.
California's Electricity Rates: A Burden for Residents
A recent report by the California Public Utilities Commission (CPUC) revealed that the average Californian household spends a significantly higher amount on electricity compared to the national average. This disparity in electricity rates can be attributed to a number of factors, including the financial costs associated with wildfire prevention measures, investments in renewable energy infrastructure, and maintenance of aging electrical grids, even as the state considers revamping electricity rates to clean the grid.
Examples of Utility Company Spending that Raise Concerns
Consumer rights groups have specifically highlighted instances where utility companies have used customer money to fund lavish executive compensation packages, sponsor professional sports teams, and finance political campaigns. They argue that these expenditures do not provide any tangible benefits to ratepayers and should not be funded through customer bills.
The Need for Accountability and Prioritization
Proponents of the bill believe that the legislation is necessary to ensure that utility companies are held accountable for how they spend customer funds. They believe that the stricter regulations would compel utilities to prioritize investments that directly improve the quality and reliability of electricity services for Californians, alongside discussions of income-based flat-fee utility bills that could reshape rate structures.
The impending vote on the bill underscores the ongoing tension between the need for reliable electricity services and the desire to keep utility rates affordable for Californians. The outcome of the vote is likely to have a significant impact on how utility companies operate in the state and how much Californians pay for their electricity.
ITER Nuclear Fusion advances tokamak magnetic confinement, heating deuterium-tritium plasma with superconducting magnets, targeting net energy gain, tritium breeding, and steam-turbine power, while complementing laser inertial confinement milestones for grid-scale electricity and 2025 startup goals.
Key Points
ITER Nuclear Fusion is a tokamak project confining D-T plasma with magnets to achieve net energy gain and clean power.
✅ Tokamak magnetic confinement with high-temp superconducting coils
✅ Deuterium-tritium fuel cycle with on-site tritium breeding
✅ Targets net energy gain and grid-scale, low-carbon electricity
It sounds like the stuff of dreams: a virtually limitless source of energy that doesn’t produce greenhouse gases or radioactive waste. That’s the promise of nuclear fusion, often described as the holy grail of clean energy by proponents, which for decades has been nothing more than a fantasy due to insurmountable technical challenges. But things are heating up in what has turned into a race to create what amounts to an artificial sun here on Earth, one that can provide power for our kettles, cars and light bulbs.
Today’s nuclear power plants create electricity through nuclear fission, in which atoms are split, with next-gen nuclear power exploring smaller, cheaper, safer designs that remain distinct from fusion. Nuclear fusion however, involves combining atomic nuclei to release energy. It’s the same reaction that’s taking place at the Sun’s core. But overcoming the natural repulsion between atomic nuclei and maintaining the right conditions for fusion to occur isn’t straightforward. And doing so in a way that produces more energy than the reaction consumes has been beyond the grasp of the finest minds in physics for decades.
But perhaps not for much longer. Some major technical challenges have been overcome in the past few years and governments around the world have been pouring money into fusion power research as part of a broader green industrial revolution under way in several regions. There are also over 20 private ventures in the UK, US, Europe, China and Australia vying to be the first to make fusion energy production a reality.
“People are saying, ‘If it really is the ultimate solution, let’s find out whether it works or not,’” says Dr Tim Luce, head of science and operation at the International Thermonuclear Experimental Reactor (ITER), being built in southeast France. ITER is the biggest throw of the fusion dice yet.
Its $22bn (£15.9bn) build cost is being met by the governments of two-thirds of the world’s population, including the EU, the US, China and Russia, at a time when Europe is losing nuclear power and needs energy, and when it’s fired up in 2025 it’ll be the world’s largest fusion reactor. If it works, ITER will transform fusion power from being the stuff of dreams into a viable energy source.
Constructing a nuclear fusion reactor ITER will be a tokamak reactor – thought to be the best hope for fusion power. Inside a tokamak, a gas, often a hydrogen isotope called deuterium, is subjected to intense heat and pressure, forcing electrons out of the atoms. This creates a plasma – a superheated, ionised gas – that has to be contained by intense magnetic fields.
The containment is vital, as no material on Earth could withstand the intense heat (100,000,000°C and above) that the plasma has to reach so that fusion can begin. It’s close to 10 times the heat at the Sun’s core, and temperatures like that are needed in a tokamak because the gravitational pressure within the Sun can’t be recreated.
When atomic nuclei do start to fuse, vast amounts of energy are released. While the experimental reactors currently in operation release that energy as heat, in a fusion reactor power plant, the heat would be used to produce steam that would drive turbines to generate electricity, even as some envision nuclear beyond electricity for industrial heat and fuels.
Tokamaks aren’t the only fusion reactors being tried. Another type of reactor uses lasers to heat and compress a hydrogen fuel to initiate fusion. In August 2021, one such device at the National Ignition Facility, at the Lawrence Livermore National Laboratory in California, generated 1.35 megajoules of energy. This record-breaking figure brings fusion power a step closer to net energy gain, but most hopes are still pinned on tokamak reactors rather than lasers.
In June 2021, China’s Experimental Advanced Superconducting Tokamak (EAST) reactor maintained a plasma for 101 seconds at 120,000,000°C. Before that, the record was 20 seconds. Ultimately, a fusion reactor would need to sustain the plasma indefinitely – or at least for eight-hour ‘pulses’ during periods of peak electricity demand.
A real game-changer for tokamaks has been the magnets used to produce the magnetic field. “We know how to make magnets that generate a very high magnetic field from copper or other kinds of metal, but you would pay a fortune for the electricity. It wouldn’t be a net energy gain from the plant,” says Luce.
One route for nuclear fusion is to use atoms of deuterium and tritium, both isotopes of hydrogen. They fuse under incredible heat and pressure, and the resulting products release energy as heat
The solution is to use high-temperature, superconducting magnets made from superconducting wire, or ‘tape’, that has no electrical resistance. These magnets can create intense magnetic fields and don’t lose energy as heat.
“High temperature superconductivity has been known about for 35 years. But the manufacturing capability to make tape in the lengths that would be required to make a reasonable fusion coil has just recently been developed,” says Luce. One of ITER’s magnets, the central solenoid, will produce a field of 13 tesla – 280,000 times Earth’s magnetic field.
The inner walls of ITER’s vacuum vessel, where the fusion will occur, will be lined with beryllium, a metal that won’t contaminate the plasma much if they touch. At the bottom is the divertor that will keep the temperature inside the reactor under control.
“The heat load on the divertor can be as large as in a rocket nozzle,” says Luce. “Rocket nozzles work because you can get into orbit within minutes and in space it’s really cold.” In a fusion reactor, a divertor would need to withstand this heat indefinitely and at ITER they’ll be testing one made out of tungsten.
Meanwhile, in the US, the National Spherical Torus Experiment – Upgrade (NSTX-U) fusion reactor will be fired up in the autumn of 2022, while efforts in advanced fission such as a mini-reactor design are also progressing. One of its priorities will be to see whether lining the reactor with lithium helps to keep the plasma stable.
Choosing a fuel Instead of just using deuterium as the fusion fuel, ITER will use deuterium mixed with tritium, another hydrogen isotope. The deuterium-tritium blend offers the best chance of getting significantly more power out than is put in. Proponents of fusion power say one reason the technology is safe is that the fuel needs to be constantly fed into the reactor to keep fusion happening, making a runaway reaction impossible.
Deuterium can be extracted from seawater, so there’s a virtually limitless supply of it. But only 20kg of tritium are thought to exist worldwide, so fusion power plants will have to produce it (ITER will develop technology to ‘breed’ tritium). While some radioactive waste will be produced in a fusion plant, it’ll have a lifetime of around 100 years, rather than the thousands of years from fission.
At the time of writing in September, researchers at the Joint European Torus (JET) fusion reactor in Oxfordshire were due to start their deuterium-tritium fusion reactions. “JET will help ITER prepare a choice of machine parameters to optimise the fusion power,” says Dr Joelle Mailloux, one of the scientific programme leaders at JET. These parameters will include finding the best combination of deuterium and tritium, and establishing how the current is increased in the magnets before fusion starts.
The groundwork laid down at JET should accelerate ITER’s efforts to accomplish net energy gain. ITER will produce ‘first plasma’ in December 2025 and be cranked up to full power over the following decade. Its plasma temperature will reach 150,000,000°C and its target is to produce 500 megawatts of fusion power for every 50 megawatts of input heating power.
“If ITER is successful, it’ll eliminate most, if not all, doubts about the science and liberate money for technology development,” says Luce. That technology development will be demonstration fusion power plants that actually produce electricity, where advanced reactors can build on decades of expertise. “ITER is opening the door and saying, yeah, this works – the science is there.”
We Energies rate increase driven by nuclear energy costs at Point Beach, Wisconsin PSC filings, and rising utility rates, affecting electricity prices for residential, commercial, and industrial customers while supporting WEC carbon reduction goals.
Key Points
A 2021 utility rate hike to recover Point Beach nuclear costs, modestly raising Wisconsin electricity bills.
✅ Residential bills rise about $0.73 per month
✅ Driven by $55.82/MWh Point Beach contract price
✅ PSC review and consumer advocates assessing alternatives
Wisconsin's largest utility company is again asking regulators to raise rates to pay for the rising cost of nuclear energy.
We Energies says it needs to collect an additional $26.5 million next year, an increase of about 3.4%.
For residential customers, that would translate to about 73 cents more per month, or an increase of about 0.7%, while some nearby states face steeper winter rate hikes according to regulators. Commercial and industrial customers would see an increase of 1% to 1.5%, according to documents filed with the Public Service Commission.
If approved, it would be the second rate increase in as many years for about 1.1 million We Energies customers, who saw a roughly 0.7% increase in 2020 after four years of no change, while Manitoba Hydro rate increase has been scaled back for next year, highlighting regional contrasts.
We Energies' sister utility, Wisconsin Public Service Corp., has requested a 0.13% increase, which would add about 8 cents to the average monthly residential bill, which went up 1.6% this year.
We Energies said a rate increase is needed to cover the cost of electricity purchased from the Point Beach nuclear power plant, which according to filings with the Securities Exchange Commission will be $55.82 per megawatt-hour next year.
So far this year, the average wholesale price of electricity in the Midwestern market was a little more than $25.50 per megawatt-hour, and recent capacity market payouts on the largest U.S. grid have fallen sharply, reflecting broader market conditions.
Owned and operated by NextEra Energy Resources, the 1,200-megawatt Point Beach Nuclear Plant is Wisconsin's last operational reactor. We Energies sold the plant for $924 million in 2007 and entered into a contract to purchase its output for the next two decades.
Brendan Conway, a spokesman for WEC Energy Group, said customers have benefited from the sale of the plant, which will supply more than a third of We Energies' demand and is a key component in WEC's strategy to cut 80% of its carbon emissions by 2050, amid broader electrification trends nationwide.
"Without the Point Beach plant, carbon emissions in Wisconsin would be significantly higher," Conway said.
As part of negotiations on its last rate case, WEC agreed to work with consumer advocates and the PSC to review alternatives to the contracted price increases, which were structured to begin rising steeply in 2018.
Tom Content, executive director of the Citizens Utility Board, said the contract will be an issue for We Energies customers into the next decade
"It's a significant source (of energy) for the entire state," Content said. "But nuclear is not cheap."
WEC filed the rate requests Monday, one week after the withdrawing similar applications. Conway said the largely unchanged filings had "undergone additional review by senior management."
WEC last week raised its second quarter profit forecast to 67 to 69 cents per share, up from the previous range of 58 to 62 cents per share.
The company credited better than expected sales in April and May along with operational cost savings and higher authorized profit margin for American Transmission Company, of which WEC is the majority owner.
Wisconsin's other investor-owned utilities have reported lower than expected fuel costs for 2020 and 2021, even as emergency fuel stock programs in New England are expected to cost millions this year.
Alliant Energy has proposed using about $31 million in fuel savings to help freeze rates in 2021, aligning with its carbon-neutral electricity plans as it rolls out long-term strategy, while Xcel Energy is proposing to lower its rates by 0.8% next year and refund its customers about $9.7 million in fuel costs for this year.
Madison Gas and Electric is negotiating a two-year rate structure with consumer groups who are optimistic that fuel savings can help prevent or offset rate increases, though some utilities are exploring higher minimum charges for low-usage customers to recover fixed costs.
Pakistan Nuclear Energy advances clean power with IAEA guidance, supporting SDGs via electricity generation, nuclear security, and applications in healthcare, agriculture, and COVID-19 testing, as new 1,100 MW reactors near grid connection.
Key Points
Pakistan Nuclear Energy is the nation's atomic program delivering clean electricity, SDGs gains, and IAEA-guided safety.
Pakistan is utilising its nuclear technology to achieve its full potential by generating electricity, aligning with China's steady nuclear development trends, and attaining socio-economic development goals outlined by the United Nations Sustainable Development Goals.
This was stated by Pakistan Atomic Energy Commission (PAEC) Chairperson Muhammad Naeem on Tuesday while addressing the 64th International Atomic Energy Agency (IAEA) General Conference (GC) which is being held in Vienna from September 21, a forum taking place amid regional milestones like the UAE's first Arab nuclear plant startup as well.
Regarding nuclear security, the PAEC chief stated that Pakistan considered it as a national responsibility and that it has developed a comprehensive and stringent safety and security regime, echoing IAEA praise for China's nuclear security in the region, which is regularly reviewed and upgraded in accordance with IAEA's guidelines.
Many delegates are attending the event through video link due to the novel coronavirus (Covid-19) pandemic.
On the first day of the conference, IAEA Director General Rafael Mariano Grossi highlighted the role of the nuclear watchdog in the monitoring and verification of nuclear activities across the globe, as seen in Barakah Unit 1 at 100% power milestones reported worldwide.
He also talked about the various steps taken by the IAEA to help member states contain the spread of coronavirus such as providing testing kits etc.
In a recorded video statement, the PAEC chairperson said that Pakistan has a mutually beneficial relationship with IAEA, similar to IAEA assistance to Bangladesh on nuclear power development efforts. He also congratulated Ambassador Azzeddine Farhane on his election to become the President of the 64th GC and assured him of Pakistan's full support and cooperation.
Naeem stated that as a clean, affordable and reliable source, nuclear energy can play a key role, with India's nuclear program moving back on track, in fighting climate change and achieving the Sustainable Development Goals (SDGs).
The PAEC chief informed the audience that two 1,100-megawatt (MW) nuclear power plants are near completion and, like the UAE grid connection milestone, are expected to be connected to the national grid next year.
He also highlighted the role of PAEC in generating electricity through nuclear power plants, while also helping the country achieve the socio-economic development goals outlined under the United Nations SDGs through the application of nuclear technology in diverse fields like agriculture, healthcare, engineering and manufacturing, human resource development and other sectors.
Ford Oakville EV investment secures government funding, Unifor deal, and plant retooling, channeling $500 million plus $1.98 billion for Canadian electric vehicle manufacturing, Windsor engine contracts, and 2025 production, strengthening Ontario's auto industry.
Key Points
Government and Ford will retool Oakville for EVs, creating jobs under a Unifor deal and Windsor engine work.
✅ $500M government funding for plant retooling
✅ Ford commits $1.98B; five new EVs by 2025
✅ Unifor deal adds Windsor engine work, jobs
The federal government and Ontario have pledged to spend up to $500 million to make the Ford plant in Oakville, Ont., able to build electric vehicles, aligning with efforts to capitalize on the U.S. EV pivot underway.
The future of the plant has been a key question for Canada's automotive industry, as moves like GM's Ontario EV deal point to broader changes, ever since the Unifor union started negotiating with the automaker for a new three-year pact to cover the company's Canadian workforce.
The two sides struck a deal a few hours after a midnight strike deadline on Tuesday morning, one that will see the company commit $1.98 billion to build five new electric vehicles and an engine contract that could yield new EV jobs in Windsor, Ont.
Ford has previously committed to spending $11 billion US to develop and manufacture electric vehicles, but so far all of that money was earmarked for Ford plants in Mexico and the company's home state of Michigan.
"With Oakville gaining such a substantial portion of Ford's planned investment, the assembly plant and its workers are better set for employment going forward," said Sam Fiorani, vice-president of global forecasting at AutoForecast Solutions.
Unifor's 'unique' Ford deal includes 5 new electric vehicles in Oakville, engine for Windsor plants Currently, the plant builds the Ford Edge and Lincoln Nautilus, but concerns over the plant's future emerged earlier this year when a report suggested Ford was contemplating scrapping the Edge altogether. The new vehicles will come as welcome news for the plant, even as Fiorani says he worries that demand for the electric vehicles (EV) has so far not lived up to the hype.
"The EV market is coming, and Ford looks to be preparing for it. However, the demand is just not growing in line with the proposed investment from all vehicle manufacturers," he said.
Plant needs upgrade first And the plant can't simply flip a switch and start building an entirely new type of vehicle. It will require a major retooling, and that will require time — and cash — to happen, which is where government cash comes in, as seen with a Niagara Region battery plant supporting the EV supply chain.
As first reported by the Toronto Star, the two branches of government have committed to spent up to $500 million combined to upgrade the plant so that it can build electric vehicles.
"The retooling will begin in 2024 with vehicles rolling off the line in 2025," Unifor president Jerry Dias said. "So we know this is a decades-long commitment."
It's not clear what portion of the cash will come from what branch of government, but CBC News has previously reported that Wednesday's throne speech is expected to contain a number of policies aimed at beefing up Canada's electric vehicle industry, as EV assembly deals are putting Canada in the race, both on the consumer side and for businesses that build them.
Ontario's minister of economic development and trade welcomed the news of a tentative deal on Tuesday and confirmed that Queen's Park legislators stand ready to do their part, as shown by Honda's Ontario battery investment moves in the province.
"Our government will always work with our federal colleagues, workers and the auto sector to ensure the right conditions are in place for the industry to remain stable today and seize the new opportunities of tomorrow," a spokesperson for Vic Fedeli told CBC News in an emailed statement Tuesday.
Municipal Renewable Energy Procurement surged as cities contracted 3.7 GW of solar and wind, leveraging green tariffs, community solar, and utility partnerships across the Southeast, led by Houston, RMI, and WRI data.
Key Points
The process by which cities contract solar and wind via utilities or green tariffs to meet climate goals.
✅ 3.7 GW procured in 2020, nearly 25% year-over-year growth
✅ Houston runs city ops on 500 MW solar, a record purchase
✅ Southeast cities use green tariffs and community solar
Cities around the country bought more renewable energy last year than ever before, reflecting how renewables may soon provide one-fourth of U.S. electricity across the grid, with some of the most remarkable projects in the Southeast, according to new data unveiled Thursday.
Even amid the pandemic, about eight dozen municipalities contracted to buy nearly 3.7 gigawatts of mostly solar and wind energy — enough to power more than 800,000 homes. The figure is almost a quarter higher than the year before.
Half of the cites listed as “most noteworthy” in Thursday’s release — from research groups Rocky Mountain Institute and World Resources Institute — are in the region that stretches from Texas to Washington, D.C.
Houston stands out for the sheer enormity of its purchase: In July, it began powering city operations entirely from nearly 500 megawatts of solar power — the largest municipal purchase of renewable energy ever in the United States, as renewable electricity surpassed coal nationwide.
The groups also feature smaller deals in North Carolina and Tennessee, achieved through a utility partnership called a green tariff.
“We wanted to recognize that Nashville and Charlotte were really blazing a new trail,” said Stephen Abbott, principal at the Rocky Mountain Institute.
And the nation’s capital shows how renewable energy can be a source of revenue: It’s leasing out its public transit station rooftops for 10 megawatts of community solar.
All of these strategies will be necessary for scores of U.S. cities to meet their ambitious climate goals, researchers believe. An interactive clean energy targets tracker shows all 95 clean energy procurements from the year in detail.
Tracker Even before former President Donald Trump promised to remove the United States from the Paris Climate Accord, a lack of federal action on climate left a void that some cities and counties were beginning to fill, as renewables hit a record 28% in a recent month. In 2015, the first year tracked by researchers at the Rocky Mountain Institute and the World Resources Institute, municipalities contracted to buy more than 1 gigawatt of wind, solar and other forms of clean energy.
But when Trump officially set in motion the withdrawal from the climate agreement, the ranks of municipalities dedicated to 100% clean energy multiplied. Today there are nearly 200 of them. The growth in activity last year reflects, in part, that surge of new pledges.
“It takes a while to get city staff up to speed and understand the options, and create the roadmap and then start executing,” Abbott said. “There is a bit of a lag, but we’re starting to see the impact.”
Even in Houston — one of the earliest to begin procuring renewable energy — there has been a steep learning curve as market forces change and prices drop, including cheaper solar batteries shaping procurement strategies, said Lara Cottingham, Houston’s chief of staff and chief sustainability officer.
No matter how well resourced and educated their staff, cities have to clear a thicket of structural, political and economic challenges to procure renewable energy. Most don’t own their own sources of power. Nearly all face budget constraints. Few have enough land or government rooftops to meet their goals within city limits.
“Cities face a situation where it’s a square peg in a round hole,” Cottingham said.
The hurdles are especially steep in much of the Southeast, where only publicly regulated utilities can sell electricity to retail customers, even large ones such as major cities. That’s where a green tariff regime comes in: Cities can purchase clean energy from a third party, such as a solar company, using the utility as a go-between.
Early last year, Charlotte became the largest city to use such a program, partnering with Duke Energy and two North Carolina solar developers to build a solar farm 50 miles north in Iredell County. At first, the city will pay a premium for the energy, but in the latter half of the 20-year contract, as gas prices rise, it will save money compared to business as usual.
“Over the course of 20 years, it’s projected we would save about $2 million,” Katie Riddle, sustainability analyst with Charlotte, told the Energy News Network last year.
The growing size of projects, innovative partnerships like green tariff programs, and the improving economics all give Abbott hope that renewable energy investments from cities will only grow — even with the Trump presidency over and the country back in the Paris agreement.
And when cities meet their goals for procuring renewable energy for their own operations, they must then turn to an even bigger task: reducing the carbon footprint of every person in their jurisdiction with broader decarbonization strategies and community engagement.
“The city needs to do its part for sure,” said Houston’s Cottingham. “Then we have this challenge of how do we get everyone else to.”
