Floating Solar Plus Wave Energy Smackdown For Fossil Fuels
Everybody is talking about a new EU clean power project that pairs floating solar with offshore wind turbines, but they’re missing half the story. Wave energy is also part of the project. The wave part is not getting much attention, probably because wave-to-electricity conversion has fallen behind wind and solar in the renewable energy race. Nevertheless, if all goes according to plan, the waters of the EU will be peppered with wave conversion devices as well as floating solar panels.
More Offshore Solar & Wind Turbines With Wave Energy, Too
The EU project is tackling the problem of how to make room for new offshore energy industries in busy coastal waters. Finding sites for new offshore wind farms can be a tough row to hoe, as offshore wind fans in the US can testify.
The new project is called EU-SCORES for “European SCalable Offshore Renewable Energy Sources.” The idea is to pair wind turbines with other clean power systems, with the aim of reducing the overall footprint of marine energy development.
EU-SCORES comes under the umbrella of the Dutch Marine Energy Centre, which will assess two sites for hybrid marine energy systems. One is a solar-plus-wind site in Belgium, which has been getting a lot of attention, and rightfully so. Floating solar is a relatively new idea that has been catching on fast for application to inland water bodies including reservoirs as well as natural lakes and ponds. The idea of setting solar panels afloat in the open sea poses new technology challenges.
In that regard, EU-SCORES shares some similarities with the CrossWind offshore wind project under way in the Netherlands, which is also on track to receive floating solar panels.
However, EU-SCORES seems to be taking a much more aggressive approach to hybridizing offshore wind farms. As DMEC describes it, the “full-scale demonstrations are intended to prove how the increased power output and capacity installed per km2 will reduce the amount of marine space needed, thereby leaving more space for aquaculture, fisheries, shipping routes and environmentally protected zones.”
“Additional benefits achieved by co-using critical electrical infrastructures and exploring advanced operation and maintenance methodologies supported by innovative autonomous systems should lower the costs per MWh,” DMEC adds.
Wave Energy: It’s All About Co-Location, Location, Location
Where were we? Oh right, wave energy. If you caught that thing about co-using, that’s a critical issue for wave energy stakeholders. Translating the infinite, 24/7 motion of waves into electricity is a tantalizing goal, but one of the factors holding back the wave energy field is the relatively high cost of shunting clean kilowatts from seagoing wave energy generators over to coastal communities.
Back in 2014, the United Nations’ International Renewable Energy Agency took a look at the wave energy field and recorded 100 projects around the world, all of which were still in the pilot and demonstration phases. The early-stage nature of the technology made it difficult to project future costs for commercial-level projects. However, IRENA did come up with the figure of 22% for the proportion of lifetime costs that could be ascribed to power take-off systems.
IRENA also estimated that installation, operation, and maintenance, and mooring would account for another 41% of lifetime costs for wave energy projects. Co-location with offshore wind turbines would presumably shave away some of those costs as well.
About Those Locations…
Another kind of challenge for the wave energy industry is that the recovery potential varies considerably from one place to another. The one-size-fits-all nature of wind turbines and solar panels does not apply as much to the wave energy field, and that has slowed the development of more mature, efficient supply chains.
In 2016, the US Department of Energy’s National Renewable Energy Laboratory looked at the problem and noted that “wave energy technology is still an emerging form of renewable energy for which large-scale grid-connected project costs are currently poorly defined.”
“Ideally, device designers would like to know the resource conditions at economical project sites so they can optimize device designs. On the other hand, project developers need detailed device cost data to identify sites where projects are economical. That is, device design and siting are, to some extent, a coupled problem,” the lab continued.
A New Burst Of Energy For Wave Energy
Regardless of the challenges, wave energy fans have persisted, and it looks like all that hard work is about to pay off. The wave energy harvesting end of the EU-SCORES project is being attached to an offshore wind farm in Portugal, using buoy-type wave harvesting devices developed by the Swedish company CorPower Ocean, as the firm’s Commercial Director Kevin Rebenius is happy to explain.
“We see great value in showcasing the highly consistent and complementary power profile of wave energy, and how this can be combined with wind and solar to deliver a more stable and predictable electricity system based purely on renewables,” Rebenius said.
CorPower Ocean’s contribution to the wave energy field is a pumping system modeled on natural pumps such as those found in the human heart.
According to CorPower, its device can produce 5 times more electricity per ton than other wave energy harvesters, partly by enabling superior performance during calm periods and partly by maintaining performance during storms. Here, let’s have them explain.
“CorPower WECs can harvest the same amount of Annual Energy from a buoy with 1/10 volume compared to conventional point absorber WEC. 1. As comparison, a 300kW CorPower WEC has a diameter of 9m and weighs 60 tonnes. Getting large amounts of electricity from a small device significantly reduces CAPEX. The compact lightweight devices are also less costly to transport, install and service, bringing down OPEX.”
There Had To Be A Green Hydrogen Angle In There Somewhere…
CorPower is aiming to make the case for commercial viability by 2024. Meeting that goal will also provide a boost to other companies involved with EU-SCORES. For those of you keeping score at home, that includes the offshore floating solar company Oceans of Energy along with the familiar names of RWE, EDP, ENEL Green Power, and Simply Blue Group.
EU-SCORES could also add another notch in the belt of green hydrogen fans. CorPower, for one, is already making the pitch.
“The multi-source demonstrations in EU-SCORES will showcase the benefits of more consistent power output harnessing complementary power sources including waves, wind and sun, creating a more resilient and stable power system, higher capacity factors and a lower total cost of the power system. These aspects will also improve the business case for green hydrogen production, by allowing electrolysers to run at higher utilisation,” CorPower enthuses.
For those of you new to the topic, electrolysis refers to electrical systems that pop hydrogen gas out of water. That doesn’t make any sense at all from a climate action perspective if the electricity is sourced from fossil energy, but sub in renewables and the whole picture shifts.
The renewable energy angle is also a rather significant improvement over the current state of affairs, in which the global supply of hydrogen is sourced primarily from natural gas and coal. With the addition of seagoing solar panels and wave energy devices envisioned by EU-SCORES, it looks like end of the fossil grip on the global hydrogen economy is in sight.

GM may have decided to pull the plug on the forward-looking Chevy Brightdrop electric van a few months ago, but don’t let that stop you, but don’t let that fool you. Right now might be the best time ever to get your hands on one.
SKIP THE STORY: jump right to the deals (trusted affiliate link).
It’s hard to overstate how good the deals on Chevy’s Brightdrop got while GM was still trying to build up demand for its fleet-focused van, and now that the company has decided to stop production, the deals have gotten even better, with a newly announced $699 lease for 39 mo. with $2,999 down through January 2nd — and that’s before you factor in an additional $3,000 discount reserved for Costco Executive Members!
Despite that, I’ve heard more than one fleet manager express hesitation at the thought of adding a discontinued product to their fleet, even if it is a killer discount. To them, I offer the following, model-agnostic rebuttal:
Legacy brands support their products
Companies like GM aren’t going anywhere soon, and neither are the customers they’ve spent millions of dollars acquiring over the past several decades. They’ll keep building parts and offering service and maintenance on vehicles like the Brightdrop for at least a decade — not least of which because they have to!
GM sells each Brightdrop with a minimum 8 year/100,000 mile warranty on the battery and other key components, which can be extended either through GM itself or through reputable third-party companies like Xcelerate Auto for seven more.
There are precious few large fleets out there looking at 15 year, 200-plus thousand mile vehicle replacement cycles. For those that are, however, all indications so far are that the vehicle’s battery health and general performance will still be well within usable limits.
So, yes: parts longevity and manufacturer support will be there (something I’d be less confident about with a startup like Rivian or Bollinger, for example), but there’s more.
Section 179 and local incentives
The One Big, Beautiful Bill Act (OBBBA) of 2025 gutted America’s energy independence goals and ensuring its auto industry would fall even further behind the Chinese in the EV race, but the loss of Section 45W wasn’t the only change written into the IRS’ rulebook. Section 179, an immediate expense reduction that business owners can take on depreciable equipment assets, has been made significantly more powerful for 2025.
The section 179 expense deduction is limited to such items as cars, office equipment, business machinery, and computers. This speedy deduction can provide substantial tax relief for business owners who are purchasing startup equipment.
The revised Section 179 tax credit (or, more accurately, expense reduction) allows for a 100% deduction for equipment purchases has doubled to $2.5 million, with a phase-out kicking in at $4 million of capital investments that drops to zero at $6.5 million. That credit and can be applied to new and used vehicles, as well as charging infrastructure, battery energy storage systems, specialized tools, and more (as long as they’re new to you).
What’s more, with regional incentives like the up to $15,000 off a new medium-duty van available from Illinois utility ComEd, the net cost of GM’s $699 promo lease drops to ~$315/mo., and there is still state money out there, as well, depending on where you live.
All of which is to say: don’t let a little thing like GM discontinuing the Brightdrop convince you to skip it. If you do that, the bean counters that killed off the Buick Grand National, GMC Syclone, and Pontiac Fiero win.

US Energy Information Administration (EIA) data released on November 25 and reviewed by the SUN DAY Campaign reveal that, during the first nine months of 2025 and for the past year, solar and battery storage have dominated growth among competing energy sources, while fossil fuels and nuclear power have stagnated.
Solar set new records in September
EIA’s latest “Electric Power Monthly” report (with data through September 30, 2025), once again confirms that solar is the fastest-growing source of electricity in the US.
In September alone, electrical generation by utility-scale solar (>1 megawatt (MW)) ballooned by well over 36.1% compared to September 2024, while “estimated” small-scale (e.g., rooftop) solar PV increased by 12.7%. Combined, they grew by 29.9% and provided 9.7% of US electrical output during the month, up from 7.6% a year ago.
Moreover, generation from utility-scale solar thermal and photovoltaic systems expanded by 35.8%, while that from small-scale systems rose by 11.2% during the first nine months of 2025 compared to the same period in 2024. The combination of utility-scale and small-scale solar increased by 29.0% and produced a bit over 9.0% (utility-scale: 6.85%; small-scale: 2.16%) of total US electrical generation for January-September, up from 7.2% a year earlier.
And for the third consecutive month, utility-scale solar generated more electricity than US wind farms: by 4% in July, 15% in August, and 9% in September. Including small-scale systems, solar has outproduced wind for five consecutive months and by over 40% in September.
Wind leads among renewables
Wind turbines across the US produced 9.8% of US electricity in the first nine months of 2025 – an increase of 1.3% compared to the same period a year earlier and 79% more than that produced by US hydropower plants.
During the first nine months of 2025, electrical generation from wind plus utility-scale and small-scale solar provided 18.8% of the US total, up from 17.1% during the first three quarters of 2024.
Wind and solar combined provided 15.1% more electricity than did coal during the first nine months of this year, and 9.8% more than the US’s nuclear power plants. In fact, as solar and wind expanded, nuclear-generated electricity dropped by 0.1%.
Renewables are now only second to natural gas
The mix of all renewables (wind, solar, hydropower, biomass, and geothermal) produced 8.7% more electricity in January-September than they did a year ago, providing 25.6% of total US electricity production compared to 24.2% 12 months earlier.
Renewables’ share of electrical generation is now second to only that of natural gas, which saw a 3.8% drop in electrical output during the first nine months of 2025.
Solar + storage have dominated 2025
Between October 1, 2024, and September 30, 2025, utility-scale solar capacity grew by 31,619.5 MW, while an additional 5,923.5 MW was provided by small-scale solar. EIA foresees continued strong solar growth, with an additional 35,210.9 MW of utility–scale solar capacity being added in the next 12 months.
Strong growth was also experienced by battery storage, which grew by 59.4% during the past year, adding 13,808.9 MW of new capacity. EIA also notes that planned battery capacity additions over the next year total 22,052.9 MW.
Wind also made a strong showing during the past 12 months, adding 4,843.2 MW, while planned capacity additions over the next year total 9,630.0 MW (onshore) plus 800.0 MW (offshore).
On the other hand, natural gas capacity increased by only 3,417.1 MW and nuclear power added 46.0 MW. Meanwhile, coal capacity plummeted by 3,926.1 MW and petroleum-based capacity fell by an additional 606.6 MW.
Thus, during the past year, renewable energy capacity, including battery storage, small-scale solar, hydropower, geothermal, and biomass, ballooned by 56,019.7 MW while that of all fossil fuels and nuclear power combined actually declined by 1,095.2 MW.
The EIA expects this trend to continue and accelerate over the next 12 months. Utility-scale renewables plus battery storage are projected to increase by 67,806.1 MW (a forecast for small-scale solar is not provided). Meanwhile, natural gas capacity is expected to increase by only 3,835.8 MW, while coal capacity is projected to decrease by 5,857.0 MW, and oil capacity is anticipated to decrease by 5.8 MW. EIA does not project any new growth for nuclear power in the coming year.
SUN DAY Campaign’s executive director Ken Bossong said:
The Trump Administration’s efforts to jump-start nuclear power and fossil fuels are not succeeding. Capacity additions from solar, wind, and battery storage continue to dramatically outpace those from gas, coal, and nuclear, and by growing margins.

The bZ3X is off to a strong start as Toyota’s most affordable electric SUV, starting at around $15,000 in China.
The bZ3X is a $15,000 Toyota electric SUV in China
Toyota’s joint venture, GAC Toyota, launched the bZ3X in China this March, an affordable, compact electric SUV aimed at young families.
The bZ3X is Toyota’s “first 100,000 yuan-level pure electric SUV,” starting at just 109,800 yuan, or roughly $15,000.
By May, the electric SUV was the best-selling foreign-owned EV in China, beating out the Volkswagen ID.3, Nissan N7, BMW i3, and Volkswagen ID.4 CROZZ.
According to the latest update, the bZ3X remains a hot seller. GAC Toyota announced that bZ3X sales exceeded 10,000 units for two consecutive months, with 10,010 units sold in November. Cumulative deliveries have now surpassed 62,000 units.
GAC Toyota recently put the electric SUV through rigorous testing on a winter road trip across China, “showcasing its impressive capabilities as a 100,000-yuan-class pure electric vehicle.”
Measuring 4,645 mm in length, 1,885 mm in width, and 1,625 mm in height, the bZ3X is about the same size as BYD’s popular Yuan Plus (sold as the Atto 3 overseas).
Inside, the electric SUV is a major upgrade over the Toyota vehicles we’re accustomed to, with advanced ADAS features, smart storage, and large digital screens.
The bZ3X is available in seven different trims in China, two of which include a LiDAR. Upgrading to the LiDAR version costs 149,800 yuan ($20,500).
Toyota’s electric SUV is available with 50.04 kWh and 67.92 kWh battery pack options, providing a CLTC range of 430 km (267 miles) and 610 km (379 miles), respectively.
Less than two weeks ago, GAC Toyota launched pre-sales for the bZ7, a new flagship electric sedan. According to Toyota, the new flagship EV “possesses a higher level of intelligence than any of Toyota’s offerings in global markets,” as the automaker fights to regain market share in China’s fierce auto market.
