Parking lots are becoming as important as cars in climate change efforts

It’s not just cars that will be going through energy transition in the years ahead. The parking lots where EVs recharge are a growing focus of construction efforts linked to climate change and carbon reduction.
A law approved in France last month requires that parking lots with 80 or more spaces be covered by solar panels within the next five years. For the biggest parking lots, those with more than 400 spaces, three years has been granted to have at least half of the parking lot’s surface area covered by solar.
Similar renewable energy design ideas are expected to gain more market share in the U.S. if not necessarily through a federal mandate.
“You’ll see a lot of the same stuff that you’re seeing in France and other countries, but it probably won’t necessarily play out the same way, in terms of federal action versus state action,” said Bill Abolt, vice president and lead of energy business for infrastructure consulting firm AECOM.
As local and state governments create mandates for renewable energy deployment, and the federal government takes an incentive-based approach to encourage climate technology through measures like the Inflation Reduction Act, major corporations are making their own commitments to solar power.
Target, Home Depot, Walmart and renewable energy
Target revamped one of its California stores with solar panel carports this spring. Home Depot is making efforts to have all of its stores use only renewable energy by 2030, while Walmart hopes to achieve this by 2040. These efforts won’t only come through producing renewable power on-site — procurement of renewable energy from utility-scale projects is among strategic options to meet these goals — but investing in solar power for store locations will become more prevalent.
“You have a lot of significant companies that have stepped up and made commitments to renewable energy and similar things with local governments and institutions. So, there’s no doubt that that level of investment has accelerated the development of technology, the deployment of more cost effective solar,” Abolt said.
The cost to install solar has dropped by more than 60% over the past decade, according to the Solar Energy Industries Association.
“There’s no doubt that the cost curve of solar gets better and better all the time and will continue to do so. Private business has done a lot, and we’re seeing even more private investment likely to happen as a result,” Abolt said.
Global commercial real estate company CBRE is partnering with renewable energy company Altus Power to work with clients including many Fortune 500 companies on solar projects.
“The topics that are top of mind for these corporations right now are decarbonization and energy efficiency and energy resiliency,” said Lars Norell, co-founder and co-CEO of Altus Power. “The No. 1 answer is building-sited clean energy,” he said.
Norell said it has now become possible for businesses of all sizes to consider renewable energy projects.
“Something that Walmart or IKEA or Amazon does, smaller family-owned businesses come to us and say ‘Should we do the same thing? Could our roof hold solar?’ The answer in almost all those cases is absolutely yes,” he said.
Public expectations and pressure from boards are key factors in why major corporations tend to act quicker than smaller companies when it comes to renewable energy. “In many cases, smaller companies don’t have quite such an audience that is expecting them to act, but many of them are acting sort of out of self-interest or because they would like to save money,” Norell said.
Solar power and commercial real estate
Solar carports and rooftop solar are the primary solar designs being adopted in the world of commercial real estate.
“We find that there is almost no debate around the wisdom of putting solar in a parking lot,” Norell said. “We believe that rooftop solar and carport solar are going to be easier for most communities to not only accept but embrace as a way to make clean energy.”
In recent years, an increasing number of solar projects have been built over commercial parking lots, and state governments have created incentives specifically for solar carports, including the 2018 Solar Massachusetts Renewable Target, and the Maryland Energy Administration Solar Canopy Grant Program, which provides funding to incentivize the use of solar carports and parking garages, with EV chargers included on site. It has provided up to $250,000 per solar carport project, creating an incentive for commercial businesses to invest in the projects.
“Increasing power prices and more government support, like in France where they mandated it, we think will mean that more parking lots are going to have carports,” Norell said.
Commercial retail centers and logistics buildings are prime targets for solar. Commercial retail centers, like grocery stores, consume higher levels of energy and often feature big parking lots. Logistics buildings like warehouses feature large rooftops that are optimal places to implement rooftop solar energy.
Altus Power forecasts that most buildings will have a solar power system over the next decade.
With the growing production and consumption of EVs — the International Energy Agency reported that U.S. electric car sales doubled in market share to 4.5% in 2021, reaching 630,000 EVs sold — solar-powered commercial businesses become more beneficial to consumers requiring EV chargers in parking lots.
The same will be the case for warehouses and distribution centers.
“Once we start getting good at having electrical-powered van fleets and trucks, all those trucks come to those logistical buildings, and that’s an excellent spot to put up fleet chargers, so that when the truck is busy … we take the opportunity to charge its electrical battery as well,” Norell said. “We can charge it with clean electricity because we’re making solar power on the roof, and that’s then going into the truck.”
Renewables increased their output by almost 10% and provided nearly a quarter of US electrical generation in 2024, according to newly released US Energy Information Administration (EIA) data.
Solar was still No 1
Solar remained the US’s fastest-growing source of electricity in 2024. Utility-scale and “estimated” small-scale (e.g., rooftop) solar combined increased by 26.9% in 2024 compared to the same period in 2023, according to the SUN DAY Campaign, which reviewed EIA’s “Electric Power Monthly” report data.
Utility-scale solar thermal and photovoltaic expanded by 32%, while small-scale solar increased by 15.3%. Together, solar was nearly 7% (6.91%) of total US electrical generation for the year.
In December alone, electrical generation by utility-scale solar expanded by 42% compared to December 2023.
Small-scale solar (systems <1 MW) accounted for 27.9% of all solar generation and provided 1.9% of the US electricity supply in 2024. In fact, small-scale solar PV generates over five times more electricity than utility-scale geothermal.
2024 renewables milestones
The electrical output of US wind farms in 2024 grew by 7.7% year-over-year. Wind remains the largest source of electrical generation among renewable energy sources, accounting for 10.3% of the US total.
Wind and solar combined provided more than 17.2% of US electrical generation during 2024. The mix of all renewables – wind, solar, hydropower, biomass, geothermal – provided 24.2% of total US electricity production in 2024 compared to 23.2% of electrical output a year earlier.
Between January and December, electrical generation by renewables grew by 9.6% compared to the same period the year before – nearly three times the growth rate of natural gas (3.3%) and over 10 times that of nuclear power (0.9%).
In December alone, electrical generation by renewables grew by 10.1% compared to December 2023.
Wind and solar together produced 15.9% more electricity than coal and came close to matching nuclear power’s share of total generation (17.2% vs. 17.8%).
The mix of renewables reinforced their position as the second largest source of electrical generation, behind only natural gas.
“Renewable energy sources now provide a quarter of the nation’s electricity,” said the SUN DAY Campaign’s executive director, Ken Bossong. “Consequently, the rash efforts of the Trump Administration to undermine wind, solar, and other renewables will have serious negative consequences for the nation’s electricity supply and the economy.”

Tesla has applied for a permit to operate a ride-hailing service in California, but it will be using human drivers rather than the promised robotaxi.
Last year, Tesla CEO Elon Musk claimed that Tesla would launch “unsupervised self-driving in Texas and California in Q2 2025.”
However, we suspected that this would not be “unsupervised self-driving’ in customer vehicles like Tesla has been promising since 2016, but an internal fleet with teleoperation support in a geo-fenced area for ride-hailing services, much like Waymo has been doing for years.
Sure enough, Musk confirmed last month that this was the plan for Austin in June. We describe this as a “moving of the goal post” for Tesla.
With the focus on Austin in June, Tesla stopped talking about California, which was announced to happen at the same time as Texas last year.
Now, Bloomberg reports that Tesla has applied for a ride-hailing permit in California:
The electric vehicle manufacturer applied late last year for what’s known as a transportation charter-party carrier permit from the California Public Utilities Commission, according to documents viewed by Bloomberg. That classification means Tesla would own and control the fleet of vehicles.
But this application is for a regular ride-hailing service, like Uber, albeit for an internal fleet rather than vehicles operated by customers.
Tesla has yet to apply for a permit to operate driverless vehicles:
In its communications with California officials, Tesla discussed driver’s license information and drug-testing coordination, suggesting the company intends to use human drivers, at least initially. Tesla is applying for the same type of permit used by Waymo, Alphabet Inc.’s robotaxi business. While Tesla has approval to test autonomous vehicles with a safety driver in California, it doesn’t have, nor has applied for, a driverless testing or deployment permit from the state’s Department of Motor Vehicles, according to a spokesperson.
Musk claimed that he believes Tesla will be able to achieve “unsupervised self-driving” in California by “the end of the year”, but he has claimed that every year for the past decade.
The latest available data shows that Tesla’s Full Self-Driving system is achieving about 500 miles between critical disengagement. Tesla has stated that it believes it needs to reach 700,000 miles between critical disengagement to be safer than humans.
Electrek’s Take
This is just a step for Tesla to test ride-hailing services ahead of autonomy. A nothing burger, really, since ride-hailing has obviously been solved already by several companies, Lyft, Uber, Didi, etc.
What needs to be solved is autonomous driving.
As I have been saying for the last year, I am sure Tesla will be able to launch an internal fleet with teleoperation support in a geo-fenced area for a ride-hailing service in California later this year like it plans to do in Austin in June, but that’s nowhere near what Tesla promised since 2016.
It’s a moving of the goal post, and it’s basically just proving that Tesla is able to do something similar to Waymo – 5 years later.

Tesla drivers in China are using the new Full Self-Driving update and are racking up fines as the system drives in bike lanes and makes illegal turns.
As we reported earlier this week, Tesla has started to release advanced driver-assist features sold under its Full Self-Driving (FSD) package in China.
The feature is called “Autopilot automatic assisted driving on urban roads” as Tesla seems more cautious about using the term “Full Self-Driving” in China, but it is a feature known for being in the FSD package everywhere else.
Tesla has been facing a lot of issues in releasing FSD features in China. The automaker has been limited in its neural net training due to restrictions about data coming in and out of the country, and it found it difficult to adapt to regulations regarding bus lanes and other China-specific road rules.
CEO Elon Musk warned that FSD in China would be a problem during Tesla’s earnings call last month due to the different rules. He mentioned bus lanes as an example:
By the way, were about the biggest challenges in making FSD work in China is the bus lanes are very complicated. And there’s like literally like hours of the day that you’re allowed to be there and not be there. And then if you accidentally go in that bus lane at the wrong time, you get an automatic ticket instantly. So, it’s kind of a big deal, bus lanes in China.
The automated ticketing system is not just for bus lanes and Tesla owners are learning about it the hard way.
Tesla owners have been testing out the features in live streams on social media and some of them are reporting getting numerous tickets for using FSD.
For example, this Tesla driver received 7 tickets in the space of a single drive because the FSD drove in bike lanes and made illegal maneuvers:
Car News China tracked several live streams and customer feedback on Chinese social media, and the consensus appears to be that it’s “pretty good, but with lots of bugs”.
The drivers are particularly impressed with how “natural” FSD drives, but they also noted that it still
Where the system lacks is the understanding of local traffic rules (such as no use of shoulder/bike lanes on turns, similar to the bus lane rules that Elon talked about in the most recent earnings call) and the sporadic use of wrong lanes (e.g. going straight in a left or right turn only lane) or navigation showing the vehicle in one lane when in fact it’s in another or wrong perception of objects (red balloons as traffic lights). Many of the live streams counted the number of traffic violations from the vehicle and the number of points that would have been taken off or licenses suspended (12 points = suspension) as a result.
Chinese media websites are now getting flooded with Tesla vehicles running red traffic lights, failing to recognize green lights, and driving on restricted lanes, like the video above.
The report also highlights how Tesla is facing strong competition in ADAS in China, with competitors like Nio, Xpeng, BYD, and others launching competitive products, which is not necessarily the case in other markets for Tesla.
Electrek’s Take
I feel like this is likely going to result in bad PR for Tesla in China. You can’t have drivers losing their licenses because FSD doesn’t recognize bike lanes.
Now, of course, Tesla will say that the driver remains responsible, but I don’t know how good Tesla’s messaging is on that front in China.
It’s going to be an interesting story to track in the coming months.
