Solar power

Prof. Christopher Knittel joins the Climate One podcast to discuss energy policy and his research on the costs associated with homeowners implementing rooftop solar. “Rooftop solar is raising people's rates,” says Knittel. We should continue to “subsidize rooftop solar in a way that's not regressive, that is not leaning harder on those homes that cannot install solar.” Thinking about: “what is the best, most efficient, and [the] fairest way to make that [equity] happen.”  

Fast Company’s Adele Peters highlights Firma Power, a clean energy developer co-founded by MIT alumni aimed at working with data centers to use clean alternatives to gas power. “We started the company with the hypothesis that despite the fact that 98% of what’s in the queue is wind, solar and storage, that’s not getting tapped as the default path to power for large loads—so there’s got to be some market frictions and barriers there,” says Jesse Jenkins SM ’14, PhD ’18.  

Writing for The Boston Globe, Prof. Christopher Knittel and graduate student Fischer Espiritu Argosino make the case that in Massachusetts the “current compensation structure for the electricity produced by solar panels turns a climate solution into an inequitable cost shift that burdens many residents.” They add: “The state needs to prioritize large-scale wind and solar deployment and fix how residential solar exporters are compensated…. Massachusetts has long been a clean-energy leader. It can remain one by showing that decarbonization and affordability can go hand in hand.”

Postdoctoral associate Stewart Isaacs SM ’19 PhD ’24 speaks with Physics Today reporter Toni Feder about his passion for the sport of jump roping, research into solar-powered egg incubators for use in West Africa, and his work at MIT focused on addressing climate change and social inequities through the development of clean energy systems. “In jump rope, you have the basic building blocks of tricks. You need to combine them in ways that look interesting and are creative and fun to do. In engineering, you have the basic building blocks of physics. When you need to solve a problem, you need to come up with a creative solution to get there,” says Isaacs of the intersection between jump roping and scientific research. “And jump rope is hard. To be really good at it takes a lot of effort. The habits of working hard and problem-solving are also very useful in engineering.”

Johanna Mayer and Katie Hafner from Scientific American’s “The Lost Women of Science podcast spotlight the late former Prof. Mária Telkes and her work focused on the development of solar energy. “Dr. Mária Telkes died in 1995, at age 94,” says Mayer. “But her legacy lives on. Today, the number of people installing solar panels in their homes is consistently rising – and in a recent Pew study, 39% of homeowners surveyed said they were seriously considering going solar.”

Ubiquitous Energy, an MIT startup, has created a transparent photovoltaic glass coating, called UE Power, that can turn any surface into a tiny solar panel, reports Teodosia Dobriyanova for Mashable. “The company, however, is prioritizing the use of UE Power on windows in an attempt to help buildings reduce their colossal climate footprint,” writes Dobriyanova.

Ross Trethewey, co-host of This Old House, visits Prof. Vladimir Bulović, director of MIT.nano, to learn more about the future of solar technology, including an electricity-generating film that can be applied to windows and other materials. “Dramatic advancements are on the horizon,” says Bulović. “We can make solar cells that don’t weigh very much at all so deployment of them on top of your roof could be as simple as unrolling a carpet and stapling it to the roof with a plug. Maybe your windows will be turned into solar cells.” 

Quaise Energy, a startup out of MIT’s Plasma Science and Fusion Center, has developed a millimeter wave drilling system to access layers of rock that reach over 700 degrees Fahrenheit, making geothermal power more accessible, reports Adele Peters for Fast Company. “Wind and solar [power] take up quite a bit of land,” writes Peters. “If geothermal power can be affordable anywhere, it could help fill an important gap in getting to 100% renewable electricity.”

Ubiquitous Energy, an MIT startup, is developing technology to transform windows into surfaces that capture solar energy, reports Catherine Clifford for CNBC. “Ubiquitous makes a coating for windows that uses semiconducting materials to convert sunlight into electricity,” writes Clifford. “The coating is just nanometers thick and tiny wires connect the solar window to electrical systems where the energy is used.”

MIT startup Ubiquitous Energy has created transparent solar panels that can also generate electricity, reports Adele Peters for Fast Company. “The windows, with two panes of glass that are sealed together, have wires that can be connected either directly to something next to the window – such as a light or electronic blinds – or connected to a battery in the building or back into the electric grid,” writes Peters.

Boston Globe correspondent Scott Kirsner spotlights CubicPV, an MIT startup, which is creating solar cells that more efficiently convert sunlight into energy.

MIT researchers have analyzed the role of long-duration energy storage technologies and found that large storage systems have the potential to lower electricity prices in a carbon-free grid by up to 40%, writes Eric Roston for Bloomberg. 

Fast Company reporter Kristin Toussaint writes that a study by MIT researchers finds shutdowns and lockdowns caused by the coronavirus pandemic led to clearer skies and increased solar output in Delhi. “I think we’ve been able to get a glimpse of how the world can look like if we actually have clean air,” says research scientist Ian Marius Peters.

A new study by MIT researchers finds that temperature increases caused by climate change could lead to a reduction in the energy produced by solar panels, reports Scott Snowden for Forbes. The researchers found that “on average, photovoltaic power output reduces by 0.45% for each degree increase in temperature.”

In an article for Bloomberg News, Noah Smith highlights a study by MIT researchers that examines the factors influencing the decline in solar prices. The researchers found that, “from 1980 to 2001, government-funded research and development was the main factor in bringing down costs, but from 2001 to 2012, the biggest factor was economies of scale,” Smith explains.
