Transitioning to a world powered by renewable energy is key to tackling climate change. Here you can find the latest good news related to our clean energy transition, covering wind, solar, green hydrogen, hydropower, and more.
Ultrathin "honeycomb" solar panels achieve record efficiency
One day, cities and hopefully everything else will be powered by renewable resources like wind and solar. To do that, though, we will need to continue to improve on our renewable tech, like creating solar panels that can absorb solar energy in many different levels of sunlight. A new development Read More...
How do solar panels break? And how do we fix them?
At the National Renewable Energy Laboratory (NREL) in Golden, Colorado, teams of scientists and researchers spend large parts of their day jumping on, twisting, smashing, and generally coming up with various ways of breaking solar panels. It’s not malice, it’s not incompetence. It's not Read More...
Refueling on Mars: making biofuel from astronaut wastewater
As space exploration develops further, scientists and engineers are innovating more outlandish ways for humans to survive beyond our planet. What was once magic becomes science as experts think outside the box and brilliantly repurpose resources in closed environments, such as growing lettuce in Read More...
Quantum charging could cut EV charging from hours to minutes
Current owners of electric vehicles can cruise along knowing that they’re not adding any CO2 emissions into the atmosphere. While they can ride guilt-free, these joy rides can still be inconvenienced by the headache of having to wait around half an hour at a high-powered public charger, or even Read More...
Oregon wastewater facility makes its own power with human waste
Two weeks ago, we wrote a piece on upcycling your “business,” going into the green uses some companies found for human waste. Innovation and recycling mean looking everywhere possible for solutions, and The Optimist Daily loves writing about the ones that are found… even if they come out of Read More...
The James Dyson Award: a call to young inventors
The Optimist Daily has written about many winners of the James Dyson Award. This is an international design award that celebrates, encourages, and inspires the next generation of design engineers. It is open to current and recent design engineering students and is run by the James Dyson Foundation, Read More...
These battery-free sensors fly like dandelion seeds
Wireless sensors are a versatile technology used to measure all sorts of conditions, without the restraint of being attached to a stationary object the whole time. They have many applications such as in medicine - like this wireless sensor which monitors bone health - or in measuring environmental Read More...
How green hydrogen is taking off
Hydrogen is key to a major energy shift in our society. Many sectors of the economy and the power grid can decarbonize by switching to green hydrogen. The market for hydrogen is expected to grow to $2.5 trillion by 2050, and many industries, such as air travel, see the writing on the wall. Read More...
This is how we could clean our solar panels without water
The water footprint of solar power may rarely come to mind. It should because cleaning the dust off of photovoltaic panels requires hundreds of millions of gallons of water per year. In a bid to come up with a solution, MIT scientists have recently invented an alternative cleaning system that Read More...
To save money and gas, driving slower helps
Many of us take the speed limits on the side of the road as, well, more of a suggestion than a hard line never to cross. Whether on the highway or in midtown, many of us feel we’re losing time or just plain bored if we’re not in the fast lane. Gas prices are rising, though, and even when we Read More...
