Last week, the nation of Portugal achieved something remarkable. For 107 hours—about four days—the country ran on nothing but wind, solar and hydro power.
Congratulations, kilt-wearers, and descendants of William Wallace! Your country’s seas are about to become the proud guardians of the world’s largest floating wind farm.
Now this is a gadget. Just look at the 6-megawatt direct-drive generator, equipped with a huge permanent magnet rotor: it was designed by General Electric’s engineers and it is one of the largest of its kind that ever built.
There’s a growing demand for greener, safer renewable energy sources. Sun, wind, water, biomass, waves and tides, and the heat of the soil, all provide alternatives to non-renewable energy.
The price of wind and solar is steadily dropping, leading researchers to conclude that CO2 emissions from power production in the US could be significantly reduced within 15 years. And to distribute this energy, they’re calling on America to build an “electron superhighway.”
Construction for the first phase of Morocco’s Noor 1 power plant is nearing completion. Once complete in 2020, the solar farm will be the largest of its kind in the world. But even now, the plant’s half-million solar mirrors are already visible from space.
As the world’s top carbon offenders attempt to one-up each other with commitments in Paris this week, one country is quietly snickering from the sidelines. That’d be Uruguay, which already sources a staggering 94.5% of its electricity from renewables.
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.
Fusion power has seemed like science fiction — a boundless energy source that would light up the world forever, if only we could figure out how to contain it. And yet we’re always about thirty years away from solving that mystery. Until now.
Earlier this week, Amazon Web Services announced that it was contracting the construction of a 208 megawatt wind farm in North Carolina.
When it comes to renewable energy, Denmark is officially kicking ass. Yesterday, Denmark’s wind farms produced 116% of national electricity demands, allowing the country to export power to Norway, German, and Sweden. According to The Guardian, that figure had risen to 140% by early Friday morning.
Golf is a dying sport, and country club memberships are seen as an elitist relic of the past. But cultural changes are only one reason golf courses are falling out of favor: The chemical-laden, water-guzzling greens are especially irresponsible for areas hit by drought. Here’s an idea from Japan for those sunny green…
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.
I don’t go to shopping malls much these days–in fact, they kinda terrify me. But if a geothermally heated, solar powered, sky-garden capped extravaganza like this ever made its way into my neighborhood, okay, I’d probably check it out.
As Elon Musk revealed in an earnings call earlier this week, people preordered a shit-ton of Tesla’s new batteries: Over 50,000 Powerwall units were reserved. Now some interesting math, courtesy of Bloomberg: The five million square-foot Gigafactory planned outside of Reno probably isn’t big enough to make them all.
There’s something serene about this panoramic view of the large scale construction site lit by the morning sun. The Smithland hydroelectric facility in Kentucky has been under construction since 2010—but as of this year it will generate 72 MW of new, renewable energy for the region.
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…
Facebook's first data center powered solely by renewable energy is now in operation in Altoona, Iowa. The center was expected to open in 2015, so it's ahead of schedule.
If you've visited Helsinki, you've probably spent time in its leafy Esplanade Park at the center of the city. Now Helsinki has turned the ground below the park into a subterranean lake which can keep buildings and other civic operations cool as part of a growing network that replaces traditional air conditioning…
