There’s no question that some homeowners feel a twinge of envy when they see solar panels appearing on homes in their neighborhood. The twin benefits of cutting utility costs and participating in renewable energy are alluring to many.

But as those homeowners consider going solar, many never take the plunge because of concerns about affordability, maintenance and uncertainties around qualifying for tax credits and other state and local rebates. For all its appeal, going solar can seem a bit daunting.

But there are more plentiful financing options available to many Texas homeowners that offer accommodating paths for acquiring solar. They also provide solutions to concerns around maintenance and affordability.

Two innovative strategies for switching to solar

Solar energy providers have been working diligently to deliver more convenient pathways for consumers to make the switch. Recently, two new strategies were introduced in Texas: direct, loan-based ownership, and third-party ownership.

Direct system ownership

With this option, homeowners take out a loan to cover the cost of their solar system and its installation. They can then repay that loan over timeframes ranging from five to twenty-five years.

There are varying rates and terms available to accommodate the preferences and goals of individual homeowners. And while manufacturer warranties and installer workmanship warranties have been available to homeowners, it is important to look for companies that offer guarantees for an extended period of time given that most systems can last several decades. For example, Freedom Forever offers a 25-year production guarantee that provides consumers with a measure of comfort around the long-term costs of owning these systems.

Third-party ownership

Another solar financing option involves third-party ownership using a Power Purchase Agreement (PPA) or lease. With a PPA option, a third-party owns the system, and homeowners either agree to buy power at a pre-defined rate per kWh or through a set monthly payment. Homeowners also have the option of leasing the panels for comparable pre-defined rates or monthly payments. (Maybe add one more sentence that explains the difference between PPAs vs lease).

With these two options, the third party insures and maintains the system. This alleviates some of the maintenance and up front cost concerns that have held some back from solar.

Issues to consider before making the switch

Even with the availability of these new options, solar power doesn’t always make sense for everyone. Your personal energy goals and preferences, as well as your tax situation, are important factors to consider when making this decision. Here are some questions folks should ask before making the switch:

  • Would I prefer owning the system outright or relying on a third-party to handle insurance and maintenance?
  • Am I looking for monthly savings now through a PPA or lease or would I prefer the quickest payback and return on investment?
  • Do I have a tax liability that enables me to get a Federal Tax Credit?

The answers to these questions will help you determine which option, if any, makes sense for you. It’s important to remember there is no “best solution for everyone” when considering your options; there’s only the question of what’s right for you.

Other important considerations

Keep in mind that not everyone will qualify for one of the solar options described above. Even in these cases, your state, local utility or a regional credit union may offer alternative financing options that can help you access solar.

Home equity lines of credit may also be a fitting option for some. Dsireusa.org is an excellent resource to help you investigate what incentives and programs are available in your area.

Final tips

As with any important financial decision, it’s a homeowner’s’ responsibility to practice due diligence in terms of assessing what they can afford and who they buy from. Here are some recommended best practices:

  1. Always get several quotes from various companies.
  2. Ask about production guarantees and warranties.
  3. Ask about the need of a service panel upgrade at the start.
  4. Verify that the company you choose offers products that will work with your home construction and roof.
  5. Prioritize solar providers with an extensive list of authorized dealers, such as Freedom Forever.
  6. Confirm that your prospective solar partner has purchasing options around loans and financing and can help you identify the option that best suits your needs.

The good news is that more homeowners than ever before can now feel more comfortable moving to solar. The new options described above for financing and maintenance can make that switch considerably less daunting than it seemed only a few years ago.

Houston researchers develop heating method to recover critical minerals from e-waste

hot new research

Researchers at Rice University have developed a new technique to efficiently recycle electronic waste and harvest critical minerals using rapid heating.

Most electronic devices use flame-retardant plastic. The plastic is formulated from a critical metal called antimony.

However, recapturing antimony is typically a challenging task since it first has to be released from the plastic. As it is released, other compounds can form, such as organic bromides, which are toxic and difficult to capture. However, the organic bromides can also be reused and have applications in industrial chemicals when safely captured.

“Conventionally heating the plastic releases the antimony in a volatile and difficult-to-collect form as well as creating and releasing hazardous organic bromide compounds,” Leo Haoxin Ye, first author of the paper and a graduate student at Rice, said in a news release. “Other options are risky or more impractical, such as using strong acids, organic solvents or multistep treatment options.”

To address this issue, leading Rice chemistry professor James Tour, Ye and their team adapted Tour’s flash Joule heating technique, which heats materials to hundreds of degrees Celsius in milliseconds, according to Rice.

The team ground up flame-retardant plastic waste and placed it between two sheets of electrically heated carbon paper before using what’s known as isothermal-clamped flash Joule heating to release and collect the antimony.

The team found that limiting the time the plastic spent in the high temperature range dramatically reduced the production of the hazardous organic bromide compounds. The plastic remained between 200 degrees and 500 degrees Celsius for only 9.4 milliseconds, according to Rice.

Through the process, the team recovered 90 percent of antimony from tested materials and converted 83 percent of the bromide into hydrogen bromide. Their findings were published this month in the journal Nature Chemical Engineering.

“Isothermal-clamped flash Joule heating could improve the speed, safety and practicality of antimony recovery from discarded flame-retardant plastics,” Tour added in the release. “This represents an important step forward to conserving and reusing our critical antimony supply while also regenerating bromide salts for reuse.”

The study noted that the world is currently trending toward producing 82 million metric tons of flame-retardant plastic waste by 2030, which adds to the fact that e-waste is the fastest-growing solid waste stream in the world.

The research was funded by the Air Force Office of Scientific Research and the U.S. Army Corps of Engineers.

Tesla unveils new Roadster sports car, which can thrust itself in the air

Tesla Talk

Tesla has unveiled its new Roadster sports car, which can thrust itself in the air, among other engineering bells and whistles. But drivers shouldn't expect to take it for a spin anytime soon.

Elon Musk's electric car company rolled out its second-generation Roadster at a Thursday event, showing off a set of cold gas thrusters and a “multi-mode” suction system that can fling the car in the air for short spurts and spin the vehicle mid-flight.

“Turns out the future does have flying cars,” Musk, Tesla's CEO, wrote on his social media platform X shortly after.

That future could be a ways off, however, given the regulatory hurdles for flying vehicles and the tangle of state rules that still need to be met.

“I’m not sure every state is going to allow a driver in the middle of traffic to suddenly elevate himself and fly," said David Vladeck, a Georgetown Law professor and former director of the FTC’s Bureau of Consumer Protection. “There is going to be a long process to let anything like that on a road.”

Thursday's event was hosted at the Texas rocket testing and development center for SpaceX — Musk's publicly-traded rocket company — and Tesla's executives noted that they “borrowed” some SpaceX technology to get the new Roadster in the air. Beyond quick jumps and flips, Tesla also said the car can accelerate from zero to 60 miles (96.6 km) an hour in less than a second.

This launch arrived after years of delays and anticipation around the new Roadster — and Tesla shares climbed in morning trading on Friday before falling amid a sell-off in companies tied to artificial intelligence.

The wait isn't completely over. Musk said production for consumers won't begin until 2028. Tesla also didn't immediately set a price tag on its latest EV.

Tesla was taking reservations for Roadster “rocket” car purchases on its website Friday morning, though the fine print said there was no guarantee when the vehicle would be delivered — or whether it would be delivered at all.

Bryant Walker Smith, former vice chair of a Department of Transportation advisory group on innovation, was unimpressed — though he did note Musk's ability to keep Tesla's stock high.

“This was a demonstration of a one-off car using a technology around for many years and will not be coming to public roads in 2028," said Smith, a law professor at the University of South Carolina. “Tesla pretty uniquely has been able to sell itself on a future that is an order of magnitude greater than reality.”

Musk has repeatedly said that the future of driving will be autonomous — and Austin-based Tesla has focused much of its business on building out self-driving features for its vehicles and, more recently, launching its own (still limited) robotaxi business.

But the company maintains that the Roadster will be made to have humans behind the wheel, calling the EV the “best of the last human-driven cars.”

Thursday's demo was technically autonomous “to make sure we don’t kill anyone,” Musk noted. But long-term, he said, the new Roadster will be “the only manually driven car that Tesla makes.”

“This is not necessarily a safety-optimized car,” Musk later added, met by laughter from the audience. But “it takes the fun meter to 11 out of 10.”

Tesla's first Roadster was launched back in 2008. And in 2018, Musk went as far as placing one on a rocket — with a mannequin dubbed “Starman” in the driver's seat — and launching it into space.

Again, the second-generation Roadster isn't immediately hitting the market. And whether the ambitious new vehicle boosts the company's bottom line remains to be seen.

In second-quarter earnings reported over the summer, Tesla's profits fell as the company spent more on research and development for its robotaxi and robotics businesses — which cut into money made from an otherwise sharp increase in vehicle sales. Net income totaled $1.11 billion for the period, while revenue climbed to $28.24 billion.

Texas Exchange for Energy & Climate Entrepreneurship (TEX-E) has named its latest expert in residence.

The Houston-based energy transition nonprofit recently announced that New Climate Ventures will join the newly established program. The Expert-in-Residence partnership aims to connect TEX-E Fellows with "the people and organizations shaping the future of energy and entrepreneurship," the nonprofit previously announced.

Taylor Chapman, an investment principal at New Climate Ventures, sits on TEX-E's board of directors. New Climate Ventures invests in early-stage startups building next-gen technologies in the energy, materials and fuels sectors. The venture capital firm's portfolio includes Houston-based clean energy startups like Solidec, Syzygy Plasmonics and Rheom Materials.

“If you know me, you know that I'm passionate about ensuring that my beloved hometown, Houston, is the energy capital of the future — not just of the past," Chapman said in a LinkedIn post. "TEX-E is building a key piece to ensure that's the case: a strong pipeline of graduate and college students immersed [and] versed in the world of energy [and] climate entrepreneurship."

TEX-E says the partnership with New Climate Ventures will allow its fellows opportunities to learn from investors that work with emerging companies and understand how they evaluate new technologies.

TEX-E announced Houston-based geothermal unicorn Fervo Energy and venture capital firm Mercury Fund as its first experts in residence in August. At the time, it said the partnerships would allow its fellows to network and work with Tim Latimer, CEO of Fervo; Sarah Jewett, COO of Fervo; and Blair Garrou, managing partner of Mercury Fund.

The nonprofit was founded in 2022 through partnerships with MIT Martin Trust Center for Entrepreneurship and Greentown Labs. It works with university students from six schools: Rice University, University of Houston, Prairie View A&M University, The University of Texas at Austin, Texas A&M University and MIT.
