Clean energy has become an even more divided topic in the US

While the majority of Americans would like to see more clean energy from solar and wind farms — support for new renewable energy projects has started to wane, according to a recent Pew Research Center survey. It also found a drop in interest in electric vehicles following Biden administration policies to slash greenhouse gas emissions and Republican backlash.

The share of people who favor more solar power has dropped from 90 to 78 percent since 2020, the survey found. Support for wind power among survey participants similarly dropped more than 10 percentage points to 72 percent over the past four years. And just 29 percent of adults said they’d consider an EV as their next car purchase, compared to 38 percent last year.

A widening partisan divide on clean energy technologies seems to be driving those changes. The biggest drop in support has been among Republicans in recent years, even though there are differences between how older and younger generations of the GOP view climate change and renewable energy.

The Pew Research Center surveyed 8,638 adults in the US in May of this year. It tries to include participants representative of the US population when it comes to race, ethnicity, gender, education, political affiliation, and more.

The biggest drop in support has been among Republicans in recent years

Back in 2020, 84 percent of Republican survey participants said they’d like to see more solar farms, and 75 percent said they’d favor more wind farms in the US. That support has fallen to 64 and 56 percent, respectively, for solar and wind farms this year. More than 80 percent of Republicans surveyed, compared to 35 percent of Democrats, oppose the Environmental Protection Agency’s new standards for greenhouse gas emissions from tailpipes expected to make more than half of car sales EVs by 2032.

Those shifts in opinion coincide with the Biden administration’s push to incentivize new renewable energy projects since he was elected in 2020. President Biden signed the nation’s biggest investment in climate action and clean energy into law in 2022, the $369 billion Inflation Reduction Act (IRA). Republican lawmakers, meanwhile, have tried to slow EV adoption by attempting to roll back tax credits for EVs and block the tailpipe pollution rule.

While many Republican lawmakers have lambasted the IRA investments in EVs and renewables, a lot of the funding it created for clean tech manufacturing is actually flowing into their districts. Of $206 billion in investments so far, $161 billion is slated for projects in Republican districts, according to a recent Bloomberg analysis. Most of that money supports EV and battery manufacturing. A separate analysis by CNN similarly found that nearly 78 percent of IRA investments go to congressional Republican districts.

We’ll have to wait and see if that infusion of cash happens to shift Republicans’ views on renewables. But the tides could also turn again with younger Republicans, who are far more optimistic about solar and wind energy than their older counterparts. Only 22 percent of Republicans aged 65 or older in the survey said that expanding renewable energy production should be a priority. In contrast, 67 percent of Republicans between the ages of 18 and 29 said renewable energy ought to be the priority over coal, oil, and gas production. In general, young adults are more likely to think climate change will cause more harm in the US in their lifetime, according to another Pew survey published in October.

Threads hits 175 million users after a year

Threads hits 175 million users after a year

A year and a half ago, Threads was but a twinkle in Mark Zuckerberg’s eye.

Now, the rival to Elon Musk’s X has reached more than 175 million monthly active users, the Meta CEO announced on Wednesday.

As with any social network, and especially for Threads, monthly users only tell part of the growth story. It’s telling that, unlike Facebook, WhatsApp, and Instagram, Meta hasn’t shared daily user numbers yet. That omission suggests Threads is still getting a lot of flyby traffic from people who have yet to become regular users.

I’ve heard from Meta employees in recent months that much of the app’s growth is still coming from it being promoted inside Instagram. Both apps share the same account system, which isn’t expected to change.

Even still, 175 million monthly users for a one-year app is nothing to turn your nose up at, especially given Meta’s spotty track record of launching standalone app experiments over the years. Zuckerberg has been open to me and others that he thinks Threads has a real shot at being the company’s next billion-user app. To keep the growth story going, I’m told, Meta is focused on markets where it thinks there’s an opening to take more market share from X — Japan, for example.

For now, Threads is still a loss leader for Meta financially, though it can certainly afford to fund it indefinitely. Internally, I’m told execs are thinking about turning on ads in Threads sometime next year, though the exact plan is still up in the air. It’s easy to see how Threads could plug into Instagram’s existing ads system. And given Meta’s intentional decision to deprioritize politics and encourage lighthearted content, it could be a compelling place for advertisers looking for a more brand-safe alternative to X.

“It would be great if it gets really, really big, but I’m actually more interested in if it becomes culturally relevant and if it gets hundreds of millions of users,” the head of Instagram, Adam Mosseri, told me when Threads first launched. A year later, the app definitely has more progress to make on the cultural front. But the fact that it’s still growing means Meta has the runway to make that happen.

A designer's wild 'wind turbine wall' idea is actually becoming reality

You may have seen renderings of an eye-catching wall covered in vertical wind turbines making the rounds online. That bold concept is finally spinning into reality with a product called Airiva from designer Joe Doucet.

The initial vision was ambitious: a mesmerizing array of 25 vertical-axis turbines each connected to a generator for a combined peak output of 10 kilowatts.

While that’s an attractive figure on paper, the intermittent nature of wind means actual daily energy production could be significantly lower.

Years of refinement and testing

But Doucet didn’t just run with that initial concept. Over the past few years, his team has tweaked and tested 16 different blade configurations before settling on a helical design. They’ve refined Airiva into a modular system made up of sizable turbine units.

Each unit houses eight turbines and is expected to produce around 2,200 kWh annually. Not a massive amount on its own, but it’s enough to put a dent in domestic energy bills. In fact, an average U.S. home would need around five units to meet all its electricity needs, though that’s quite a large footprint.

4. Energy-efficient windows: Advanced window controls and materials can minimize heat loss during winter and reduce heat gain during summer, improving overall energy efficiency.

5. Reflective roofing materials: These materials can reflect more sunlight and absorb less heat, leading to lower cooling costs.

6. LED lighting: LED bulbs use up to 80% less energy than incandescent bulbs and last up to 25 times longer. They also produce less heat, which can help keep your home cooler in the summer. By replacing the most-used bulbs in your home with LEDs, you can save about $75 per year.

Also, consider using smart light bulbs, which are LED light bulbs that connect to the internet through Wi-Fi or a hub. When connected to the internet, you can control when, how long, how often and how brightly (and even what color) your bulb shines from the comfort of your cellphone, tablet, smartwatch or voice assistant. Smart light bulbs use at least 75% less energy and last 25 times longer than incandescent bulbs. Be sure to check out my top smart bulb picks here.

7. Geothermal systems: Geothermal heat pumps use the stable temperature of the ground to provide heating, cooling and hot water at high efficiencies.

8. Wind turbines: Residential wind turbines can be installed on properties to generate electricity, though they require a suitable location with enough wind.

9. Hydropower systems: Microhydropower systems can be a viable option for homes near flowing water, converting the energy of flowing water into electricity.

These technologies, along with Airiva’s wind turbines, represent a growing trend towards greener, more sustainable living. They not only help in reducing energy bills but also contribute to a lower carbon footprint, aligning with global efforts to combat climate change.

DJI expands into e-bikes and drive systems

DJI expands into e-bikes and drive systems

DJI is expanding into electric bikes in a big way with its new Avinox drive system and Amflow e-bike brand. The company best known for its drones is launching its first e-bike — the carbon fiber Amflow PL electric mountain bike — before the end of the year, complete with the mid-drive Avinox motor and fast-charging battery. It has so many smart and powerful features packed into a relatively lightweight e-bike that it should catch the attention of competitors like Bosch and Specialized.

As a showcase for DJI’s new Avinox drive system, the Amflow PL e-bike features a very impressive 120Nm of max torque and 1000W of on-demand boost power to overcome even the steepest inclines. Otherwise, its “remarkably quiet” mid-drive motor is rated for 250W of nominal output with an 850W peak. Its removable 800Wh battery can fast-charge from zero to 75 percent in a speedy 1.5 hours when using Amflow’s 2A/508W GaN charger.

Despite all that power and battery capacity, the Amflow PL weighs just 19.2kg (just over 42 pounds), thanks in part to a 2.27kg carbon fiber frame and 2.52kg Avinox drive system.

The bike features a two-inch color OLED touchscreen display integrated into the frame and an Avinox app for wireless access to the bike and all the riding data. The bike will sound an alarm in case of trouble and alert you of its location in the app. It has four pedal-assist modes, including an auto mode that adapts power delivery based on riding resistance. Rounding out the highlights is a USB charging port for your phone or bike computer, a full suspension system from Fox, and a frame that can accommodate both 27.5-inch and 29-inch rear wheels.

“Our expertise in battery and motor technology accumulated in drones and camera stabilization systems, have led us to the creation of Avinox,” says Christina Zhang, senior director of corporate strategy at DJI. “It is a natural move for DJI to expand into this field as we have been mastering the technologies essential to an electric bike system, in terms of reliable motor development, battery management, mechanical design and engineering.”

The company has also been developing intelligent driving solutions for automobiles in China over the last few years, some of which can already be found in several car models. More recently, the company expanded into the large consumer battery market with the launch of its first power stations.

The Amflow PL is expected to ship in Q4. DJI tells me to expect a pricing somewhere between €7,000 and €12,000 ($7,500 and $12,850), which puts it into direct competition with premium electric sport bikes like Specialized’s Turbo series. DJI says the Amflow PL will be available from authorized dealers in Germany, the UK, and Australia “amongst others.”
