As the leaders of 196 countries negotiate a carbon emissions goal for the planet to prevent an environmental apocalypse, the real work will fall to the companies that will need to deliver change to consumers. And no single person is doing as much to help change our energy consumption as one Elon Musk.
Earlier this year, the Clean Power Plan pledged to cut US power plant carbon emissions by 32 percent by 2050. A new study says the US can do way better than that: reducing all greenhouse gas emissions by 80 percent and running the country entirely on renewable energy by 2050.
·The giant Ivanpah solar power plant in the California Mojave Desert recently detailed how much natural gas it burned to generate power when the sun wasn’t sufficient – the equivalent to 46,000 tons of CO2 emissions in its first year, according to reports.
Solar cells suffer a strange problem: the hotter they get as the sun pours down on them, the less efficient they become at converting light into electricity. But now a team of Stanford researchers have developed a new transparent coating that can help them keep a little cooler—and more efficient.
It’s the drought but it’s not just the drought: California is currently facing unprecedented environmental challenges. It might not seem like they have a lot in common, but Saudi Arabia can teach California how to deal with its current water, energy, and transportation crises. Because, in a way, looking at Saudi…
The vast majority of solar cells sit fixed in place on top of buildings — but that means they miss out on absorbing some energy, as the sun moves through the sky. Now, researchers suggest that a few simple cuts could help create simple solar cells that track the sunlight throughout the day.
Solar cells are becoming increasingly efficient, but many still fail to make full use of the radiation that falls upon them. A new hybrid cell, however, converts unused light into heat to boost its efficiency by 20 percent.
The Solar Impulse solar-powered airplane has set off from Nagoya in Japan on its 120-hour flight to Hawaii—one the most perilous legs of its round-the-world flight.
If it’s good enough for Apple, it’s clearly good enough for Amazon. Bezos & Co. has announced that it’s channeling money into the construction and running of an 80 megawatt solar farm in Virginia.
There are many things holding up the US’s move towards renewable energy, but one of those things is not science: We already have all the technology we need to make this happen. A new study claims that a completely clean energy future is possible by 2050, and it plots roadmaps for all 50 states to achieve this goal.
Graphene, already a plenty weird wondermaterial, has an unexpected new property that could one day play a role in space exploration: When hit with light, it propels forward. Huh!
Solar power is getting much, much better. Now, a team of scientists has created the world’s most efficient nanostructured black silicon solar cell—which converts an impressive 22.1 percent of incident light into electricity.
A Swedish company claims that this small-scale concentrated solar energy system—which leans on ideas from a 19th-century Scottish clergyman—converts 34 percent of sunlight into electricity. That could make it the most efficient solar system in the world.
Tesla unveiled a new product line at its design studio in LA tonight. It’s called Tesla Energy and it’s a suite of batteries for homes and for businesses. The existence of the batteries has been one of the worst kept secrets of all time. But we are here at the announcement event and finally have some details. And…
So far, specific details are thin on the new battery designed for home use that Tesla’s announcing next week. But just based on what we do know, it’s a pretty big deal. The quest for a good battery that can store home-generated power is kind of like the holy grail for a renewable energy future. This one product might…
Key price indicators in the clean tech industry are about six years ahead of estimates, and it’s mostly thanks to companies like Tesla that are pioneering cheaper, smarter solutions for mass-market consumption which can be used across a wide range of applications. This is a very good thing for Earth.
Early this morning, Solar Impulse took off form Mandalay, headed to toward China—after more than a week spent waiting in Myanmar for weather conditions to improve for flight.
The solar eclipse that covered much of Europe today was the continent’s first in 16 years. After the last one, back in 1999, as soon as people stopped staring at the sun and got back on with their day, they caused a power surge that still stands as a UK record.
California has long been on the cutting edge of solar power, and now it has what be its most interesting plan yet: a vast solar array floating on top of wastewater ponds. The project will be built in Sonoma County, which you may know better as wine country.
Inspiration lies in the strangest of places—and for researchers at the Agency for Science, Technology & Research in Singapore, that includes the eye of moth. A new antireflective coating inspired by the creature's ocular faculties could help bump up the efficiency of solar cells.
