The legislative debate over the future of alternative energy in Florida has come down to, not surprisingly, jobs. The question is whose jobs.

Will it be jobs for Florida Power & Light and its parent company NextEra Energy, which has quietly lined up lobbyists and campaign contributions to push legislation to allow it to raise rates for all of its 4 million customers to pay for solar power plants?

Will it be jobs for a consortium of alternative energy companies, including agriculture giant Florida Crystals, that say they can produce solar and biomass at less cost to customers than the utility giants?

Or will it be jobs for solar panel manufacturers and installers, who mount rooftop assemblies on homes and businesses? They say they can feed energy into the existing power grid and offset the need for utility companies to build expensive power plants.

All hope the legislative solution being crafted in the House and Senate will include each of them, but none has any guarantees. In each of the last three years, a bill to encourage renewable energy development has been proposed and died. Florida's new governor also is no fan of renewables.

Gov. Rick Scott told voters during the campaign that he doesn't believe in climate change and is not persuaded that investing in renewable energy is a good deal. His proposed budget would eliminate the Florida Energy & Climate Commission, the volunteer board that administers state and federal energy grants and makes recommendations on state climate policy.

"There's room for the utilities to produce electricity and get it paid for, and there's room for small and midsize companies as well," said Richard Pinsky, a lobbyist for the Distributed Energy Coalition, a group of companies seeking an alternative to utility-only generation of renewable energy.

But even the chief promoter of the renewables legislation for the last two years believes that anything short of giving the utility industry the ability to control the market is derided as deregulation.

"It'll be a tough sell," said Sen. Mike Bennett, a Bradenton Republican and sponsor of the bill to allow utilities to bypass the Public Service Commission and raise their rates to build renewable energy plants. "The power companies have always been able to convince the legislative process that deregulating power is bad."

Bennett's bill, SB 1336, would not only open the door to expanded renewables, it could allow FPL to earn more than $1 billion in profits over four years by allowing its rates to increase by a percentage of its annual revenue to pay for the new solar energy plants. The company and its parent, NextEra Energy, have made passage of the bill its top legislative priority, steered $2.4 million into legislative political coffers, and hired Mike Sole, former Gov. Charlie Crist's top environmental regulator, to be its top lobbyist.

"They are guaranteed a profit based on their capital investment," Bennett explained. "So the more solar plants they build, the more equipment they buy and the more money they are allowed by law to make. They don't want somebody else building the solar because they don't get to profit."

In a recent meeting with the Miami Herald editorial board, FPL chief executive Armando Olivera said that while "there is very little growth" in customer demand right now, the company wants the Legislature to allow it to build 500 megawatts of solar-powered energy because "the fuel diversity can bring a lot of jobs here."

FPL was the only utility company to benefit from the 2008 bill that allowed it to charge customers for 101 megawatts of solar-generated energy. It cost $643 million to its customers, or $1 a month for the average customer who uses 1,200 kilowatt hours a month.

Speaking to a House committee in February, Buck Martinez, head of FPL's renewable energy division, said that the company's solar projects have earned international acclaim, come in under budget and have dropped significantly in price.

He said that while his company supports rooftop solar projects, the only people who benefit are those who have the money to install solar panels on their buildings and homes.

"The benefits would not be borne by the state," he said. "They would only benefit the individual that can afford to put it on their rooftop."

But Etan Gumerman, a Duke University professor who presented the report, Renewable Energy in the South, to the House and Senate energy committees, countered that all FPL customers benefit when others install rooftop solar because it avoids the need to build more expensive power plants in the future.

"Just because I may be a freeloader, I can still benefit if you put something on your roof," he said.

Renewable energy proponents say the Legislature should set a target for the amount of renewable energy it wants distributed in Florida and a time line for achieving it, as 29 other states have done.

"Florida is missing out on an enormous opportunity to attract clean energy to the state," said Susan Glickman of the Southern Alliance for Clean Energy, a consortium of alternative energy companies.

Bennett also agrees with the argument against his bill, saying he doesn't like the idea of giving the utilities the so-called early cost recovery that asks customers to pay for their construction costs. But he says he's a pragmatist and is not convinced that the Legislature will do anything to encourage a system that allows for more people to distribute energy by installing rooftop systems.

"Power companies do not want to give up control," he said. "I'm a huge fan of the power companies, but I'm also a huge fan of what's fair."

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

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

 

Key Points

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

✅ 7 micrometer film between electrodes adsorbs water vapor.

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

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

 

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Electricity blackouts spark protests in Iranian cities

Iran Power Outage Protests surge as electricity blackouts, drought, and a looming heat wave spark unrest in Tehran, Shiraz, and more, with chants against leadership, strikes, and sanctions-driven economic pressures mounting.

 

Key Points

Protests across Iran over blackouts, drought, and economic strain challenge authorities and demand accountability.

✅ Rolling blackouts blamed on drought, heat wave, and surging demand.

✅ Chants target leadership amid strikes and wage, water shortages.

✅ Legitimacy questioned after low-turnout election and sanctions.

 

There have been protests in a number of cities in Iran amid rising public anger over widespread electricity blackouts.

Videos on social media appeared to show crowds in Shar-e Rey near Tehran, Shiraz, Amol and elsewhere overnight.

Some people can be heard shouting "Death to the dictator" and "Death to Khamenei" - a reference to Supreme Leader Ayatollah Ali Khamenei.

The government has apologised for the blackouts, which it has blamed on a severe drought and high demand.

Elsewhere, similar outages have had political repercussions, as a widespread power outage in Taiwan prompted a minister's resignation earlier this year.

President Hassan Rouhani explained in televised remarks on Tuesday morning that the drought meant most of the country's hydroelectric power plants were not operating, placing more pressure on thermal power plants, and that electricity consumption had surged as people used air conditioning to cope with the intense summer heat.

"I apologise to our dear people who have faced problems and suffering in the past few days and I urge them to co-operate [by cutting their electricity use]. People complain about power outages and they are right," Mr Rouhani said.

A video that has gone viral in recent days shows a woman complaining about the blackouts and corruption at a government office in the northern city of Gorgan and demanding that her comments be conveyed to "higher-ups like Mr Rouhani". "The only thing you have done is forcing hijab on us," she shouts.

The president has promised that the government will seek to resolve the problems within the next two or three weeks.

However, a power sector spokesman warned on Monday that consumption was exceeding the production capacity of Iran's power plants by 11GW, and said a "looming heat wave" could make the situation worse, as seen in Iraq's summer electricity crunch this year.

Iranians have also been complaining about water shortages and the non-payment of wages by some local authorities, while thousands of people working in Iran's oil industry have been on strike over pay and conditions, as officials discuss further energy cooperation with Iraq to ease supply pressures.

There was already widespread discontent at government corruption and the economic hardship caused by sanctions that were reinstated when the US abandoned a nuclear deal with Iran three years ago, even as Iran supplies about 40% of Iraq's electricity through cross-border sales.

Analysts say that after the historically low turnout in last month's presidential election, when more than half of the eligible voters stayed at home, the government is facing a serious challenge to its legitimacy.

Mr Rouhani will be succeeded next month by Ebrahim Raisi, a hard-line cleric close to Ayatollah Khamenei who won 62% of the vote after several prominent contenders were disqualified, while Iran finalizes power grid deals with Iraq to bolster regional ties.

The 60-year-old former judiciary chief has presented himself as the best person to combat corruption and solve Iran's economic problems, including ambitions to transmit electricity to Europe as a regional power hub.

But many Iranians and human rights activists have pointed to his human rights record, accusing him of playing a role in the executions of thousands of political prisoners in the 1980s and in the deadly crackdowns on mass anti-government protests in 2009 and 2019.

New rules give British households right to sell solar power back to energy firms

UK Smart Export Guarantee enables households to sell surplus solar energy to suppliers, with dynamic export tariffs, grid payments, and battery-friendly incentives, boosting local renewable generation, microgeneration uptake, and decarbonisation across Britain.

 

Key Points

UK Smart Export Guarantee pays homes for exporting surplus solar power to the grid via supplier tariffs.

✅ Suppliers must pay households for exported kWh.

✅ Dynamic tariffs incentivize daytime solar generation.

✅ Batteries boost self-consumption and grid flexibility.

 

Britain’s biggest energy companies will have to buy renewable energy from their own customers through community-generated green electricity models under new laws to be introduced this week.

Homeowners who install new rooftop solar panels from 1 January 2020 will be able to lower their bills as many seek to cut soaring bills by selling the energy they do not need to their supplier.

A record was set at noon on a Friday in May 2017, when solar energy supplied around a quarter of the UK’s electricity, and a recent award that adds 10 GW of renewables indicates further growth.

However, solar panel owners are not always at home on sunny days to reap the benefit. The new rules will allow them to make money if they generate electricity for the grid.

Some 800,000 householders with solar panels already benefit from payments under a previous scheme. However, the subsidies were controversially scrapped by the government in April, with similar reduced credits for solar owners seen in other regions, causing the number of new installations to fall by 94% in May from the month before.

Labour accused the government last week of “actively dismantling” the solar industry. The sector will still struggle this summer as the change does not come in for another seven months, so homeowners have no incentive to buy panels this year.

Chris Skidmore, the minister for energy and clean growth, said the government wanted to increase the number of small-scale generators without adding the cost of subsidies to energy bills. “The future of energy is local and the new smart export guarantee will ensure households that choose to become green energy generators will be guaranteed a payment for electricity supplied to the grid,” he said. The government also hopes to encourage homes with solar panels to install batteries to help manage excess solar power on networks.

Greg Jackson, the founder of Octopus Energy, said: “These smart export tariffs are game-changing when it comes to harnessing the power of citizens to tackle climate change”.

A few suppliers, including Octopus, already offer to buy solar power from their customers, often setting terms for how solar owners are paid that reflect market conditions.

“They mean homes and businesses can be paid for producing clean electricity just like traditional generators, replacing old dirty power stations and pumping more renewable energy into the grid. This will help bring down prices for everyone as we use cheaper power generated locally by our neighbours,” Jackson said.

Léonie Greene, a director at the Solar Trade Association, said it was “vital” that even “very small players” were paid a fair price. “We will be watching the market like a hawk to see if competitive offers come forward that properly value the power that smart solar homes can contribute to the decarbonising electricity grid,” she said.

Alberta shift from coal to cleaner energy

Alberta Coal-to-Gas Transition will retire coal units, convert plants to natural gas, boost renewables, and affect electricity prices, with policy tools like a price cap and carbon tax shaping the power market.

 

Key Points

Shift retiring coal units and converting to natural gas and renewables, targeting coal elimination by 2030.

✅ TransAlta retires Sundance coal unit; more units convert to gas.

✅ Forward prices seen near $40 to low $50/MWh in 2018.

✅ 6.8-cent cap shields consumers; carbon tax backstops costs.

 

The turn of the calendar to 2018 saw TransAlta retire one of its coal power generating units at its Sundance plant west of Edmonton and mothball another as it begins the transition to cleaner sources of energy across Alberta.

The company will say goodbye to three more units over the next year and a half to prepare them for conversion to natural gas.

This is part of a fundamental shift in Alberta, which will see coal power retired ahead of schedule by 2030, replaced by a mix of natural gas and renewable sources.

“We’re going to see that transition continue right up from now until 2030, and likely beyond 2030 as wind generation starts to outpace coal and new technologies become available.”

Coal has long been the backbone of Alberta’s grid, currently providing nearly 40 per cent of the provinces power. Analysts believe removing it will come with a cost to consumers, according to a report on coal phase-out costs published recently.

“The open question over the next couple of years is whether they’re going to inch up gradually, or whether they’re going to inch up like they did in 2012 and 2013, by having periods of very high power prices.”

Albertans are currently paying historically low power prices, with generation costs last year averaging below $23/MWh, less than half of the average of the past 10 years.

A report released in mid-December by electricity consultant firm EDC Associates showed forward prices moving from the $40/MWh in the first three months of 2018, to the low $50/MWh range.

“The forwards tend to take several weeks to fully react to announcements, so its anticipated that prices will continue to gradually track upwards over the coming weeks,” the report reads.

The NDP government has taken steps to protect consumers against price surges. Last spring, a price cap of 6.8 cents/MWh was put in place until the spring of 2021, with any cost above that to be covered by carbon tax revenue.

Enel kicks off 90MW Spanish wind build

Enel Green Power España Aragon wind farms advance Spain's renewable energy transition, with 90MW under construction in Teruel, Endesa investment of €88 million, 25-50MW turbines, and 2017 auction-backed capacity enhancing grid integration and clean power.

 

Key Points

They are three Teruel wind projects totaling 90MW, part of Endesa's 2017-awarded plan expanding Spain's clean energy.

✅ 90MW across Sierra Costera I, Allueva, and Sierra Pelarda

✅ €88m invested; 14+7+4 turbines; Endesa-led build in Teruel

✅ Part of 2017 tender: 540MW wind, 339MW solar, nationwide

 

Enel Green Power Espana, part of Enel's wind projects worldwide, has started constructing three wind farms in Aragon, north-east Spain, which are due online by the end of the year.

The projects, all situated in the Teruel province, are worth a total investment of €88 million.

The biggest of the facilities, Sierra Costera I, will have a 50MW and will feature 14 turbines.

The wind farm is spread across the municipalities of Mezquita de Jarque, Fuentes Calientes, Canada Vellida and Rillo.

The Allueva wind facility will feature seven turbines and will exceed 25MW.

Sierra Pelarda, in Fonfria, will have four turbines and a capacity of 15MW, as advances in offshore wind turbine technology continue to push scale elsewhere.

The projects bring the total number of wind farms that Enel Green Power Espana has started building in the Teruel province to six, equal to an overall capacity of 218MW.

Endesa chief executive Jose Bogas said: “These plants mark the acceleration on a new wave of growth in the renewable energy space that Endesa is committed to pursue in the next years, driving the energy transition in Spain.”

The six wind farms under construction in Teruel are part of the 540MW that Enel Green Power Espana was awarded in the Spanish government's renewable energy tender held in May 2017.

In Aragon, the company will invest around €434 million euros, reflecting broader European wind power investment trends in recent years, to build 13 wind farms with a total installed capacity of more than 380MW.

The remaining 160MW of wind capacity will be located in Andalusia, Castile-Leon, Castile La Mancha and Galicia, even as some Spanish turbine factories closed during pandemic restrictions.

Enel Green Power Espana was also awarded 339MW of solar capacity in the Spanish government's auction held in July 2017, while other Spanish developers advance CSP projects abroad in markets like Chile.

Once all wind and solar under the 2017 tender are complete they will boost the company’s capacity by around 52%.

Electricity Market Headed for a Reshuffle as Province Vows Overhaul

Alberta Electricity Market Overhaul will add renewables like wind and solar, curb price volatility tied to natural gas, boost competition, and reward energy efficiency, while safeguarding grid reliability and investor confidence through a transition roadmap.

 

Key Points

Alberta's 2027 market redesign adds renewables, boosts competition, and cuts volatility to protect reliability.

✅ Integrates wind and solar to meet climate and affordability goals.

✅ Increases competition and efficiency; reduces price volatility.

✅ Plans transition measures to maintain reliability and investment.

 

Alberta's electricity market is on the precipice of a significant transformation. The province, long reliant on fossil fuels for power generation, has committed to a market overhaul by 2027. This ambitious plan promises to shake up the current system, but industry players are wary of a lengthy period of uncertainty that could stifle much-needed investment in the sector.

The impetus for change stems from a confluence of factors. Soaring energy bills for consumers, reflecting rising electricity prices across the province, coupled with concerns about Alberta's environmental footprint, have pressured the government to seek a more sustainable and cost-effective electricity system. The current market, heavily influenced by natural gas prices, has been criticized for volatility and a lack of incentive for renewable energy development.

The details of the new electricity market design are still being formulated. However, the government has outlined some key objectives. One priority is to incorporate more renewable energy sources like wind and solar power into the grid. This aligns with Alberta's climate change goals and could lead to cleaner electricity generation, supporting the province's path to clean electricity in the coming years.

Another objective is to introduce more competition within the market. The current system is dominated by a few large players, and the government hopes increased competition will drive down prices for consumers, as the market needs more competition to function efficiently.

While the potential benefits of the overhaul are undeniable, industry leaders are apprehensive about the transition period, with a Calgary retailer urging the government to scrap the overhaul amid uncertainty. The lack of clarity surrounding the new market design creates uncertainty for power companies. This could discourage investment in new generation facilities, both renewable and traditional, potentially leading to supply shortages in the future.

John Kousinioris, CEO of TransAlta, a major Alberta power generator, expressed these concerns. "We need a clear roadmap for the future," he stated. "Uncertainty makes it difficult to justify significant investments in new power plants, which are essential to ensure a reliable electricity supply for Albertans."

The government acknowledges the need to minimize disruption during the transition. They have promised to engage in consultations with industry stakeholders throughout the redesign process, as the province changes how it produces and pays for electricity to support long-term stability. Additionally, measures may be implemented to ensure a smooth transition and provide some level of certainty for investors.

The success of Alberta's electricity market overhaul will depend on several factors. Striking a balance between environmental sustainability, affordability, and energy security will be crucial. The government must design a system that incentivizes investment in new, cleaner power generation while maintaining reliable electricity supply at a reasonable cost for consumers.

The role of natural gas, a dominant player in Alberta's current electricity mix, is another point of contention. While the government aims to incorporate more renewables, natural gas is likely to remain a part of the equation for some time. Determining the appropriate role for natural gas in the future market will be a critical decision.

The upcoming years will be a period of significant change for Alberta's electricity market. The province's commitment to a cleaner and more competitive system holds promise, but navigating the transition effectively will be a complex challenge. Open communication, collaboration between stakeholders, and a well-defined roadmap for the future will be essential for ensuring a successful electricity market overhaul and a brighter energy future for Alberta.
