President Biden has ordered that all federal buildings and vehicles switch to renewable energy by 2050.
Wind and solar could meet 85 percent of current US electricity needs
Renewable sources may meet most power demands in 'advanced, industrialized nations,' according to a study.
Google says it offset all of the emissions it has ever generated
Google eliminates its 'entire carbon legacy' and plans to use only clean energy by 2030.
House Democrats’ climate plan calls for 100 percent EV sales by 2035
House Democrats want to eliminate the US economy’s greenhouse gas emissions, in part by pushing for 100 percent electric passenger vehicles.
Denmark's ambitious wind power plans include giant 'energy islands'
Denmark's new wind power project could boost Europe's offshore wine capacity by 54 percent.
Amazon plans new solar and wind farms in Ireland and Virginia
Months after Amazon shareholders turned down a plea by employees to do more about climate change, the company announced two new renewable energy projects. Today, Amazon shared plans for a wind farm in Ireland and a solar farm in Pittsylvania County, Virginia. When completed sometime in 2020, these projects are expected to generate a combined 168,000 MWh of clean energy annually, helping Amazon reach its goal to power 100 percent of its operations with renewable power.
China wants to put a solar farm in space by 2025
Humanity uses a lot of energy, and while solar power here on Earth is doing a reasonable job of contributing to the electricity mix, scientists have long hypothesized that gathering the sun's energy from space would be a lot more effective. And now China says it's going to be the first to do exactly that, announcing plans to build an interstellar power station that will orbit the Earth at 36,000 kilometers.
Alphabet's hot salt energy-storage project becomes its own company
Alphabet's X division has played host to a string of experimental ideas, and another one is spinning out as an independent business. Malta uses cheap, abundant materials including salt, anti-freeze and steel to store power at grid scale.
A major UK energy supplier is now 100 percent wind power
Scottish Power has become the first of the UK's "big six" energy companies to completely drop fossil fuels for electricity generation, after selling off its remaining gas plants to power company Drax in a £702 million deal. In a statement, Scottish Power said the move supported its vision to leave "carbon generation behind for a renewable future powered by cheaper green energy."
China bumps up renewable energy target to reduce reliance on coal
China, the world's biggest energy consumer, is stepping up its push into clean power with a revised renewable energy target. The nation is now aiming for renewables to account for at least 35 percent of energy consumption by 2030, whereas its previous target only stipulated "non-fossil fuels" making up 20 percent of energy use within the same time frame.
Renault is creating France's first 'smart island'
Back in February, Renault helped electrify the Portuguese islands of Madeira and Porto Santo -- a move not dissimilar to Tesla's efforts in Hawaii. Now it's at work again bringing power to the French island of Belle-Île-en-Mer, in a bid to create the first "smart island" in its home country.
Samsung targets 100 percent renewable energy use by 2020
Samsung has announced plans to power its US, Europe and China operations entirely by renewable energy sources within two years. It's already making good on its sustainability commitment in Korea, where the company is installing 42,000 square meters of solar panels in its Digital City, and is working on generating geothermal power at Pyeongtaek campus and Hwaseong campus by 2020.
Microsoft’s deep sea data center is now operational
Data centers are hot, noisy and usually inefficiently located. Microsoft's solution? Put them at the bottom of the sea. Following initial prototype testing, the company's years-long Project Natick is finally delivering Microsoft's vision of sustainable, prepackaged and rapidly deployed data centers that operate from the seafloor. Yep. Underwater.
Graphene film makes dirty water drinkable in a single step
Every year, millions of people around the world die from drinking unclean water. Now, researchers have developed a process that can purify water, no matter how dirty it is, in a single step. Scientists from Australian research organization CSIRO have created a filtration technique using a graphene film with microscopic nano-channels that lets water pass through, but stops pollutants. The process, called "Graphair", is so effective that water samples from Sydney Harbor were safe to drink after being treated.
Tesla’s big battery is undercutting Australia’s energy cartels
When Tesla installed the world's largest lithium-ion battery in South Australia last year, it came with the promise that it would revolutionize the way electricity is produced, stored and sold in a region known for blackouts and market monopolizing. Less than two months later, that promise has been delivered to the tune of a multimillion-dollar saving, as the Tesla big battery essentially noped an attempt by Australia's energy cartel to capitalize on power fluctuations and send the market into overdrive.
Nearly all new US electricity capacity was renewable in 2017
Renewable energy played an important role in the US last year... although you might not want to cheer too loudly. Data from both the Rhodium Group and the Energy Information Administration shows that solar and wind power represented 94.7 percent of the net new electricity capacity (15.8GW out of 16.7GW) added in 2017. However, that's mainly because fossil fuel power continued to fade away. Electrek noted that plant closures removed 11.8GW of utility-scale fossil fuel power from the equation -- this was more a testament to the decline of coal than a triumph for green tech.
Your solar panels could power the neighborhood during a blackout
A new set of algorithms could make it possible for renewable energy-generating homes to not only access their power reserves during outages, but share their resources with their neighbours -- a move which could play a significant role in disaster relief efforts. Self-sufficiency is an attractive factor when it comes to domestic renewable energy, but even though it's the sun generating electricity, owners of solar panels are still beholden to the grid. During an outage, their equipment powers down for safety reasons, and it's impossible to draw on the renewably-generated electricity that's waiting to be used. We've seen companies produce kit to overcome this before -- Tesla's Powerwall home battery system can untether a home from the grid for a few hours, for example -- but researchers from the University of California San Diego want to scale up the technology to have a wider and more meaningful impact.
Alphabet is using salt and antifreeze to store power from wind farms
The latest from Alphabet's experimental X division? A storage solution for renewable energy. Code named "Malta," the system uses tanks of salt and antifreeze (or another hydrocarbon liquid) to create and store energy.
Saving bats from wind turbines is easy
Renewable energy like wind power is touted as a great way to reduce our impact on the environment. Tech companies like Google and Tesla, along with cities like San Francisco, understand the need to go green. Still, even renewable sources of energy can have hidden effects on local animal populations. The world's largest solar power plant, in fact, kills thousands of birds annually at its Ivanpah, California site. A new study in Sweden found that the country's wind turbines kill tens of thousands of bats annually -- an average of 10 to 15 bats per turbine. The answer? Halt the spinning of the fans during the summer evenings when wind is low anyway.
World's largest offshore windfarm to be built in the UK
Britain is set to become home to two of the world's largest offshore wind farms after ministers approved plans for a new 1,800-megawatt project capable of supplying 1.8 million UK homes. Hornsea Project Two will be built 55 miles off the coast of Grimsby and could feature up to 300 turbines -- each one taller than the Gherkin building in London.
