During the COP28 climate conference held in Dubai last month, world leaders from over 130 governments agreed to set a goal to triple world renewable energy installations by 2030. While more effort is needed to reach that goal, one energy organization has predicted that renewables will overtake coal generation as the world’s largest electricity source in early 2025.
The International Energy Agency (IEA) released its Renewables 2023 report earlier this month, marking the first of the organization’s comprehensive climate analyses released since the 2030 goal was set at the COP28 conference. The report contains countless important insights about the next several years in renewable energy, as well as details about the sector’s expansion in 2023.
“The report shows that under existing policies and market conditions, global renewable power capacity is now expected to grow to 7,300 GW over the 2023-28 period covered by the forecast,” the IEA wrote in a press release. “Solar PV and wind account for 95% of the expansion, with renewables overtaking coal to become the largest source of global electricity generation by early 2025.”
In addition to the 2025 prediction, the agency notes that global renewable energy capacity added to energy systems increased by 50 percent in 2025, and it expects the industry to enter the largest growth period yet over the next five years.
Despite the optimistic tone, the IEA also says that renewable energy expansion will need to accelerate even more to reach the COP28 2030 goal, and the world faces the primary barrier of financing for these projects in emerging and developing economies.
“But despite the unprecedented growth over the past 12 months, the world needs to go further to triple capacity by 2030, which countries agreed to do at COP28,” the release continues.

Renewable energy sources detailed in the report include both utility-scale solar photovoltaic (PV) systems and distributed solar PV systems (like Tesla’s Virtual Power Plant pilots using Powerwalls), hydro power, onshore and offshore wind, and other smaller sources like H2 production, concentrating solar power, ocean, bioenergy and geothermal.
“Onshore wind and solar PV are cheaper today than new fossil fuel plants almost everywhere and cheaper than existing fossil fuel plants in most countries,” says Faith Birol, IEA executive director. “There are still some big hurdles to overcome, including the difficult global macroeconomic environment.”
“For me, the most important challenge for the international community is rapidly scaling up financing and deployment of renewables in most emerging and developing economies, many of which are being left behind in the new energy economy. Success in meeting the tripling goal will hinge on this.”
IEA Renewables 2023 report: a few key insights
The details in this report are vast, though we’ll highlight just a few key insights the IEA points out.
- Global solar PV prices declined by nearly 50 percent year over year in 2023, and the IEA expects cost reductions and accelerated deployment to continue.
- Last year, China commissioned as much solar PV as the entire world did in 2022, while the country’s wind power increased 66 percent year over year.
- In the U.S., the European Union (EU), India, and Brazil, solar PV and onshore wind projects are expected to more than double between now and 2028 compared to the past five years.
- Solar PV and wind account for 95 percent of the predicted 7,300 GW renewable expansion between 2023 and 2028.
- The IEA recommends more rapid policy implementation with accelerated case breakdown, which would boost renewable power capacity growth by 21 percent in the coming years, if implemented.

Tesla called ‘biggest meme stock we’ve ever seen’ by Yale associate dean

Tesla (NASDAQ: TSLA) is being called “the biggest meme stock we’ve ever seen” by Yale School of Management Senior Associate Dean Jeff Sonnenfeld, who made the comments in a recent interview with CNBC.
Sonnenfeld’s comments echo those of many of the company’s skeptics, who argue that its price-to-earnings ratio is far too high when compared to other companies also in the tech industry. Tesla is often compared to companies like Apple, Nvidia, and Microsoft when these types of discussions come up.
Fundamentally, yes, Tesla does trade at a P/E level that is significantly above that of any comparable company.
However, it is worth mentioning that Tesla is not traded like a typical company, either.
Here’s what Sonnenfeld said regarding Tesla:
“This is the biggest meme stock we’ve ever seen. Even at its peak, Amazon was nowhere near this level. The PE on this, well above 200, is just crazy. When you’ve got stocks like Nvidia, the price-earnings ratio is around 25 or 30, and Apple is maybe 35 or 36, Microsoft around the same. I mean, this is way out of line to be at a 220 PE. It’s crazy, and they’ve, I think, put a little too much emphasis on the magic wand of Musk.”
Many analysts have admitted in the past that they believe Tesla is an untraditional stock in the sense that many analysts trade it based on narrative and not fundamentals. Ryan Brinkman of J.P. Morgan once said:
“Tesla shares continue to strike us as having become completely divorced from the fundamentals.”
Dan Nathan, another notorious skeptic of Tesla shares, recently turned bullish on the stock because of “technicals and sentiment.” He said just last week:
“I think from a trading perspective, it looks very interesting.”
Nathan said Tesla shares show signs of strength moving forward, including holding its 200-day moving average and holding against current resistance levels.
Sonnenfeld’s synopsis of Tesla shares points out that there might be “a little too much emphasis on the magic wand of Musk.”
Elon Musk just bought $1 billion in Tesla stock, his biggest purchase ever
This could refer to different things: perhaps his recent $1 billion stock buy, which sent the stock skyrocketing, or the fact that many Tesla investors are fans and owners who do not buy and sell on numbers, but rather on news that Musk might report himself.
Tesla is trading around $423.76 at the time of publication, as of 3:25 p.m. on the East Coast.

Tesla makes big change to Full Self-Driving doghouse that drivers will like
Now, it is changing the timeframe of which strikes will be removed, cutting it in half. The strikes will be removed every 3.5 days, as long as no strikes are received during the time period.

Tesla is making a big change to its Full Self-Driving doghouse that drivers will like.
The doghouse is a hypothetical term used to describe the penalty period that Tesla applies to drivers who receive too many infractions related to distracted driving.
Previously, Tesla implemented a seven-day ban on the use of Full Self-Driving for those who received five strikes in a vehicle equipped with a cabin camera and three strikes for those without a cabin camera.
It also forgave one strike per week of Full Self-Driving use, provided the driver did not receive any additional strikes during the seven-day period.
Now, it is changing the timeframe of which strikes will be removed, cutting it in half. The strikes will be removed every 3.5 days, as long as no strikes are received during the time period.
The change was found by Not a Tesla App, which noticed the adjustment in the Owner’s Manual for the 2025.32 Software Update.
The system undoubtedly helps improve safety as it helps keep drivers honest. However, there are definitely workarounds, which people are using and promoting for monetary gain, and you can find them on basically any online marketplace, including TikTok shop and Amazon:

These devices are NOT to be used when operating Tesla Full Self-Driving and I’d love to see Tesla take action here.

People are marketing the product as an FSD cheat device, which the cabin-facing camera will not be able to detect, allowing you to watch something on a phone or look through the windshield at the road.
The safeguards implemented by Tesla are designed to protect drivers from distractions and also protect the company itself from liability. People are still using Full Self-Driving as if it were a fully autonomous product, and it is not.
Tesla even says that the driver must pay attention and be ready to take over in any scenario:
“Yes. Autopilot is a driver assistance system that is intended to be used only with a fully attentive driver. It does not turn a Tesla into a fully autonomous vehicle.
Before enabling Autopilot, you must agree to “keep your hands on the steering wheel at all times” and to always “maintain control and responsibility for your vehicle.” Once engaged, Autopilot will also deliver an escalating series of visual and audio warnings, reminding you to place your hands on the wheel if insufficient torque is applied or your vehicle otherwise detects you may not be attentive enough to the road ahead. If you repeatedly ignore these warnings, you will be locked out from using Autopilot during that trip.
You can override any of Autopilot’s features at any time by steering or applying the accelerator at any time.”
It is good that Tesla is rewarding those who learn from their mistakes with this shorter timeframe to lose the strikes. It won’t be needed forever, though, as eventually, the company will solve autonomy. The question is: when?

Elon Musk teases the capabilities of the Tesla Roadster once again

Elon Musk has once again teased the capabilities of the Tesla Roadster, fueling the anticipation that many have for the vehicle, despite it still having no public production or delivery date.
The Roadster is among the most anticipated vehicles in the automotive sector currently, and as Tesla has teased its capabilities, from a lightning-fast 1.1-second 0-60 MPH acceleration to potential hovering with cold-gas thrusters, people are eager to see it.
Although the design seemed to be finalized, there was still more work to be done. Earlier this year, as Tesla was showcasing some of the Roadster’s capabilities to Musk, he stated that it was capable of even more.
This pushed back its production date even further, much to the chagrin of those who have been waiting years for it.
Musk continues to tease us all, and as we sit here waiting hopelessly for it to be revealed, he said today that it is “something special beyond a car.”
The new Roadster is something special beyond a car
— Elon Musk (@elonmusk) September 17, 2025
Musk’s words were in response to a video posted by Tesla China, showing the Roadster in a new promotional video created by a fan.
The Roadster was planned to be released in 2020, but here we are in 2025, and there is still no sign of the vehicle entering production. However, Tesla did say earlier this year that it would host a demo event for the Roadster, where the company would showcase its capabilities.
Lars Moravy said earlier this year:
“Roadster is definitely in development. We did talk about it last Sunday night. We are gearing up for a super cool demo. It’s going to be mind-blowing; We showed Elon some cool demos last week of the tech we’ve been working on, and he got a little excited.”
Tesla exec gives big update on Roadster, confirming recent rumor
The delays have been attributed to “radically increased design goals” for the vehicle, which have, without a doubt, improved its capabilities, but at the same time, we just want to know if it’s ever going to come.
Tesla can always make it “better,” but at what point do you say, “Okay, it’s time to show this thing off.” They could always build another, even more capable supercar in the next ten years.
