The world has to add or replace 49.7 million miles of transmission lines by 2040 in order for countries to meet their climate goals and to achieve energy security priorities, according to a new report published by the International Energy Agency on Tuesday.
That amount is roughly equivalent to the total number of miles of electric grid that currently exists in the world currently, according to the IEA.
This remarkable scale up in the construction of transmission lines across the globe will require the annual investment in electric grids of more than $600 billion per year by 2030, which is double what current global investment levels are in transmission lines, the IEA says.
It will also require changes in how the electric grid in each country is operated and regulated.
The global focus on some clean energy technologies — including wind, solar, electric vehicles and heat pumps — is impressive, but investment in transmission lines has been insufficient and will ultimately become an ever larger bottleneck, the IEA says.
“The recent clean energy progress we have seen in many countries is unprecedented and cause for optimism, but it could be put in jeopardy if governments and businesses do not come together to ensure the world’s electricity grids are ready for the new global energy economy that is rapidly emerging,” Fatih Birol, executive director of the IEA, said in a written statement published alongside the new report.
“This report shows what’s at stake and needs to be done. We must invest in grids today or face gridlock tomorrow,” Birol said.
There are currently 1,500 gigawatts of renewable clean energy projects in what the IEA calls “advanced stages of development” that are waiting to get connected to the electric grid around the world. For some sense of perspective, a mid-size city needs a gigawatt of electricity, Microsoft co-founder and climate investor Bill Gates said in his book, “How to Avoid a Climate Disaster.”
The 1,500 gigawatts of renewable clean energy projects waiting to be connected to the electric grid is five times the total wind and solar power added around the globe in 2022, the IEA says.
Demand for electricity is going to continue to rise as more sectors of the global economy transition to electric power.
Also, the electric grids were constructed to bring electricity from locations where fossil fuels were burned to where that electricity was needed. As the world works to transition toward a clean energy economy, the electric grid will increasingly need to run from where wind and solar farms are constructed to where electricity is used.
The consequences of falling further behind in building transmission lines is dire, the IEA says.
If the electric grid grows slowly, a scenario which the IEA called the “Grid Delay Case,” then an extra almost 60 billion metric tons of carbon dioxide emissions will be released between 2030 and 2050, the IEA says. That is equal to the amount of emissions the power sector across the entire world has released over the past four years, the IEA says.
In this case, global temperature averages in 2050 would be “well above” 1.5 degrees Celsius over pre-industrial levels — the goal of the 2015 Paris Climate Agreement — and there would be a 40% chance of overshooting 2 degrees, the IEA says.
Part of the challenge is that transmission lines take so long to build, especially compared to other parts of the energy infrastructure.
Building new transmission lines takes between five and 15 years, with planning and permitting included. By contrast, new renewable energy projects take between one and five years, and new infrastructure for charging electric vehicles takes less than two years, the IEA says. Therefore, investing in transmission line infrastructure improvement and growth must happen now or it will become an ever larger and more limiting factor in global decarbonization plans.
Building transmission lines globally needs to be an issue of international cooperation, the IEA says. “Ensuring the developing world has the resources it needs to build and modernize electricity grids is an essential task for the international community,” Birol said in the written statement.
Ava Community Energy just rolled out a new program in California that pays EV and plug-in hybrid drivers for charging their cars when electricity on the grid is cleaner and cheaper.
The new Ava SmartHome Charging program, launched in partnership with home energy analytics platform Optiwatt, offers up to $100 in incentives in the first year. And because the program helps shift home charging to lower-cost hours, Ava says drivers could save around $140 a year on their energy bills.
EV and PHEV owners who are Ava customers can download the Optiwatt app for free, connect their vehicle, and let the app handle the rest. The app uses an algorithm to automatically schedule charging when demand is low and more renewable energy is available, typically overnight or during off-peak hours.
“Ava is on a mission to provide 100% clean energy to our customers by 2030,” said CEO Howard Chang. “This new program helps us get there by giving people an easy way to charge on more renewable energy while simultaneously saving money.”
Drivers who enroll get a $75 bonus for joining, and can earn an extra $25 per year if they stay enrolled. Optiwatt shifts charging to off-peak times, and it takes into account the customer’s individual schedules and preferences.
Casey Donahue, who founded Optiwatt, says this program is a win for everyone. “We can move a lot of energy use to cleaner, more affordable times by using smart algorithms and the growing EV base,” he said. “That benefits every Ava customer.”
The program is available to most EVs and plug-in hybrids. All it takes is signing up through the Optiwatt app (iOS, Android, or web) and completing a quick verification process. Savings and rewards start right away.
The Oakland-based not-for-profit public power provider aims to enroll at least 5,000 vehicles by the end of 2025. The company says this program is the first step in a broader virtual power plant (VPP) strategy. It’s powered by Lunar Energy’s Distributed Energy Resource Management System (DERMS) platform, Gridshare, which will help Ava coordinate energy from EVs, home batteries, and more.
Ava Community Energy was founded in 2018 and now serves 2 million people in Alameda County, California, and the cities of Tracy, Stockton, and Lathrop.

Jeep is teasing the new Grand Cherokee, but where’s the EV version of its best-selling SUV?
The Grand Cherokee is due for a refresh, and we just got our first look at it. Jeep claimed “the next chapter in the story of America’s best-selling full-size SUV begins” after releasing the first official images of the updated model. When will we see the Jeep Grand Cherokee as an EV?
2026 Jeep Grand Cherokee first look
Days after revealing the new Compass, Jeep is teasing another refreshed model, its best-selling Grand Cherokee.
Although it was the best-selling full-size SUV in the US last year, the Grand Cherokee is due for an update. The latest model was launched in 2021, but Jeep added a two-row version in 2022.
It remained Jeep’s top seller in the US last year with over 216,000 models sold, but sales were down 12% compared to 2023. It was also one of the best-selling plug-in hybrid (PHEV) vehicles, with over 27,500 4xe models
Jeep is giving us our first official look at the updated 2026 Grand Cherokee, inside and out. The first image previews the front end, which features new LED headlights and a revamped seven-slot grille, similar to the new Compass.
The interior is restyled with a simplified setup and other minor infotainment and climate control display adjustments. The preview also shows an added passenger screen.
When will Jeep launch the Grand Cherokee EV?
Jeep will continue to assemble the updated SUV in Detroit. The new 2026 Jeep Grand Cherokee will be available as a two-row, three-row L, and a plug-in hybrid 4xe, but when will we see an EV version? The outgoing 4xe model is already one of the top three selling PHEVs in the US, so a fully electric version would make sense.
As part of its 2023 agreement with the UAW, Jeep revealed plans to launch the Grand Cherokee EV in 2027. It was scheduled to be built at the Detroit Assembly Complex, but plans have likely changed since then.
Jeep’s new Compass will be available as an EV, but only in Europe. At least for now. Stellantis halted operations at its Brampton Assembly plant earlier this year, where the Compass is built, as it “reassesses its product strategy in North America.”
For those in the US, Jeep currently offers one EV. The Wagoneer S (pictured on the left above), Jeep’s first global electric SUV, starts at $65,200 and has a range of up to 294 miles.
Later this year, Jeep is expected to launch the Recon EV (pictured on the right above), a rugged electric SUV like a Wrangler.
Jeep is currently offering employee pricing plus an extra $1,500 cash allowance on top of the $7,500 EV tax credit on 2025 Wagoneer S models. If you’re looking to snag some savings, you can use our link to find Jeep Wagoneer S models in your area today.

Can Kia’s first electric sedan live up to the hype? After launching the EV4 in Korea, we are finally seeing it in action. A new test drive of the EV4 gives us a closer look at what to expect as Kia prepares to take it global. Here’s how it went down.
Kia EV4 test drive: The good, the bad, and the ugly
Kia claims the EV4 will “set a new standard in electric vehicles” with long-range capabilities, fast charging, and a sleek new design.
The electric sedan features a unique, almost sports-car-like profile with a long-tail silhouette and added roof spoiler.
Kia claims it is “the new look of a sedan fit for the era of electrification.” Despite its four-door design, the company is calling it a new type of sedan.
The design is not only eye-catching, but it’s also super efficient. With a drag coefficient of just 0.23, the EV4 is Kia’s most aerodynamic vehicle so far, enabling maximum driving range and efficiency.
Kia opened EV4 orders in South Korea in March, starting at about $29,000 (41.92 million won). It’s available with two battery options: 58.2 kWh and 81.4 kWh. The entry-level “Standard Air” model, powered by the 58.2 kWh battery, is rated with up to 237 miles of driving range.
The “Long-Range Air” variant starts at 46.29 million won ($31,800) and has a driving range of up to 331 miles (533 km) in Korea.
With charging speeds of up to 350 kW, the EV4 can charge from 10% to 80% in around 29 minutes. The long-range battery will take about 31 minutes.
The interior boasts Kia’s latest ccNC infotainment system with a 30″ Ultra-wide Panoramic Display. The setup includes dual 12.3″ driver displays, navigation screens, and a 5″ air conditioning panel.
With deliveries kicking off, we are seeing some of the first test drives come out. A review from HealerTV gives us a better idea of what it’s like to drive the EV4 in person.
Sitting next to Kia’s first pickup, the Tasman, the reviewer mentions the EV4 feels “particularly newer.” The test drive starts around the city with a ride quality similar to that of the K5, if not even better.
As you can see from the camera shaking, the ride feels “a bit uncomfortable” on rough roads. However, on normal surfaces and speed bumps, Kia’s electric sedan “feels neither too soft nor too hard,” just normal. The reviewer calls the EV4’s overall ride quality “quite ordinary” with “nothing particularly special about it.”
When accelerating, the electric car was smooth in the beginning but felt “a little lacking in later stages.” Overall, it should be enough for everyday use.
One of the biggest issues was that the rear window appeared too low. The rear brake lights also stick out, making it hard to see clearly through the rearview.
Keep in mind that the test drive was the Korean-spec EV4. Kia will launch the EV4 in Europe later this year and in the US in early 2026.
In the US, the EV4 will include a built-in NACS port for charging at Tesla Superchargers and a driving range of up to 330 (EPA-est) miles. Prices will be revealed closer to launch, but the EV4 is expected to start at around $35,000 to $40,000.
Would you buy Kia’s electric sedan for around $35,000? Or would you rather have the Tesla Model 3, which starts at $42,490 in the US and has up to 363 miles of range? Let us know in the comments.
