“MIT researchers concluded wood burns dirtier than coal, and determined it takes at least 44 years for replanted trees to adsorb the carbon released from burning the ones they replaced,” reports CBS News correspondent Jonathan Vigliotti.

Bruce Anderson ’73, founder and CEO of MIT spinout 247 Solar, speaks with Bloomberg Baystate Business Hour host Janet Wu about the power of solar energy and growing climate concerns for the future. “We are facing dire circumstances here,” says Anderson. “We have no clue what the climate’s tipping point is where it all of sudden goes in a direction that we cannot recover from, no matter how much carbon we remove from the air."

MIT President L. Rafael Reif and Special Presidential Envoy for Climate John Kerry discussed the urgency of addressing climate change during the Climate Grand Challenges Showcase event, reports Chris Lisinski for the State House News Service. “Climate change has been called a ‘super wicked’ problem. In Boston, that might sound like a local way of saying ‘really hard,’ but this phrase is actually a technical term,” Reif said. “It describes any enormously complex societal problem that has no single right answer and no clear finish line as well as multiple stakeholders with conflicting priorities and no central authority empowered to solve it.”

Fast Company reporter Connie Lin spotlights how Algorand, an MIT startup founded by Prof. Silvio Micali, dimmed the lights in Times Square on April 21 to help conserve energy and demonstrate how cryptocurrency could reduce energy consumption. Algorand has developed a carbon-negative blockchain protocol and “utilizes a pure proof-of-stake consensus mechanism to verify authentic transactions.”

Bloomberg News reporter Janet Wu speaks with President L. Rafael Reif and Special Presidential Envoy for Climate John Kerry during the Institute’s Climate Grand Challenges showcase event. “If you can capture the emissions -- literally, genuinely -- then you’re reducing the problem,” said Kerry of the importance of eliminating greenhouse gas emissions.

Prof. Jessika Trancik speaks with ABC News about the urgent need to transition to renewable energy sources, and how we can build a future powered by alternative energy. “Up until recently there were really significant questions about whether we could transition to another [energy] foundation,” says Trancik. “This question has now been answered in that we now have cost competitive renewable primary energy in the form of solar and wind energy and also in other types of renewable energy.”

A team of researchers from MIT and the National Renewable Energy Laboratory successfully reached a 30% jump in thermophotovoltaic (TPV) efficiency, reports Robert F. Service for Science. “[TPV] is a semiconductor structure that concerts photons emitted from a heat source to electricity, just as a solar cell transforms sunlight into power,” explains Service.

MIT announced five projects "targeting the world's toughest climate riddles" that were selected following a rigorous two-year competition, reports Benjamin Kail for Boston Business Journal. “Climate Grand Challenges represents a whole-of-MIT drive to develop game-changing advances to confront the escalating climate crisis, in time to make a difference,” says President L. Rafael Reif.

Prof. Jessika Trancik speaks with Wall Street Journal reporter Nidhi Subbaraman about the dramatic drops in costs to manufacture and sell renewable technologies. Subbaraman notes that Trancik’s research shows that “the steep drop in solar and lithium-ion battery technology was enabled by market expansion policies as well as investment in research and development by governments and the private sector.”

The MIT AI Hardware Program seeks to bring together researchers from academia and industry to “examine each step of designing and manufacturing the hardware behind AI-powered technologies,” reports Emily Bamforth for EdScoop. “This program is about accelerating the development of new hardware to implement AI algorithms so we can do justice to the capabilities that computer scientists are developing,” explains Prof. Jesús del Alamo.

The MIT AI Hardware Program is aimed at bringing together academia and industry to develop energy-optimized machine-learning and quantum-computing systems, reports Katyanna Quach for The Register. “As progress in algorithms and data sets continues at a brisk pace, hardware must keep up or the promise of AI will not be realized,” explains Professor Jesús del Alamo. “That is why it is critically important that research takes place on AI hardware."

Mashable reporter Emmett Smith spotlights how MIT researchers have developed a new technique to clear dust from solar panels without using water. The new method uses “electrostatic repulsion, where an electrode that glides above the panel electrically charges dust particles and subsequently repels them.”

Research engineer Paul Woskov speaks with Bloomberg Radio host Tom Moroney and Joe Shortsleeve about his work with Quaise Energy in developing a laser to drill holes into the earth. “There is a lot of heat contained within our planet. The amount of heat that is present, if tapped, could supply all of our energy needs for several million years,” says Woskov.

MIT engineers have developed a new contactless method to clean solar panels that could save billions of gallons of water, reports Anuradha Varanasi for Popular Science. “I was amazed at the sheer amount of pure water that is required for cleaning solar panels,” says Prof. Kripa Varanasi. “The water footprint of the solar industry is only going to grow in the future. We need to figure out how to make solar farms more sustainable.”

Researchers from MIT and MIT spinoff Quaise Energy speak with Boston Globe reporter David Abel about their work developing a new way to drill as deep as 12 miles into the Earth’s crust, using a special laser, which could provide a way to tap the geothermal energy in the rocks. “This is game-changing,” Woskov said. “We now have the potential to exploit an energy source that . . . could unleash the virtually limitless supply of energy beneath our feet.”
