The 130 giant wind turbines that sprout from the peaks, slicing the air with a rhythmic sigh, have helped Portugal to a remarkable achievement. For four and a half days in May the country ran entirely on electricity from renewable sources: wind, hydro and solar power.
Despite fears of a blackout, the lights stayed on for a record 107 hours between 6.45am on Saturday 7 May and 5.45pm the following Wednesday. — The Guardian
After a large solar array, Boulder Solar 1, came online on Dec. 12, the city was able to buy enough carbon-free electricity to power its 140 buildings, streetlights and other facilities. [...]
The renewables, plus energy efficiency savings, are estimated to save the city roughly $5 million per year [...]
The Vegas city council, after threatening to leave the grid entirely in 2015, struck a deal with NV Energy that would help the city get to 100% renewable. — qz.com
For four decades, the problem of how to create an economically viable business producing power from waves has fascinated a specialized group of engineers, many of whom are concentrated around the sea-beaten coast of Scotland. Inventors have created all sorts of strange and wonderful devices to coax energy out of the water; investors have poured millions of pounds into the effort. — Quartz
In Tijuana, another architect is devising a plan to turn the Tijuana River channel into a solar farm that could provide power to as many as 30,000 homes.
Rene Peralta, co-founder of the Tijuana firm Generica and director of an architecture master's program at San Diego's Woodbury University, thinks that his city can transform this unwieldy piece of infrastructure into a renewable energy plant and water-cleaning station. — The Los Angeles Times
A US government agency says it has attained the “holy grail” of energy – the next-generation system of battery storage, that has has been hotly pursued by the likes of Bill Gates and Elon Musk.
Advanced Research Projects Agency-Energy (Arpa-E) – a branch of the Department of Energy – says it achieved its breakthrough technology in seven years. — The Guardian
The Advanced Research Projects Agency-Energy (Arpa-E) was founded back in 2009 as part of President Obama's economic recovery plan. So-called "moonshot projects" are often too risky for private investors, but this state-run initiative may have unlocked a new technology that others, from Elon Musk...
Vancouver has become the latest city to commit to running on 100% renewable energy...The city’s ambition is to be the world’s greenest city by 2020 despite the fact Canada has had one of 'the most environmentally irresponsible national governments' for the last 10 years, [said Vancouver deputy mayor Andrea Reimer.] — The Guardian
Because of its size and intense radiation, Texas leads the nation in solar energy potential, but the solar industry has long struggled to get a foothold in the state... and solar energy currently makes up a tiny percentage of the state’s energy portfolio. That’s beginning to change. Improving technology has driven down the price of solar power, making it more competitive with other resources — even without incentives, developers say. — The Texas Tribune
Burlington’s switch to renewable energy will reduce greenhouse gas emissions, save $20 million over the next 20 years and keep energy prices stable [...]
The move is only one part of a solution for climate change, according to Taylor Ricketts, professor of Environmental Science at the University of Vermont. “Climate change is the biggest problem we face, maybe the biggest problem we’ve ever faced. But there’s no silver bullet to fix it,” he said. — pbs.org
El Hierro, the most remote of Spain's Canary Islands, is now billing itself as the world's first energy self-sufficient island that has never been hooked up to a power grid [...] This past summer, El Hierro inaugurated the Gorona del Viento power plant, a $110 million wind and water turbine farm. By the end of this year, the plant will generate all of the island's energy needs of up to 48 gigawatt hours per year. — NPR
The rainy season coincides with summer in Dakar, which means it’s the power-cut days. The heat goes up, A/Cs kick into gear and the power utility, Senelec, cannot cope. [...]
Enter solar. This potential renewable savior is a latecomer to Dakar because until recently solar power was banned in cities, as it was considered what the French pointedly call “compétition déloyale” – unfair competition.
But under pressure from Dakar’s own citizens, the ban was lifted under the last government [...]. — nextcity.org
"SolarLeaf" has been described as the world's first bioreactive façade that can help further research into algae as a potential renewable energy source. Designed by ARUP, SSC Strategic Science Consult, and Colt International, the façade was recently selected as one of 15 nominees for the prestigious Zumtobel Group Award 2014 in the award program's newest category, "Applied Innovations". — bustler.net
Soundscrapers could soon turn urban noise pollution into usable energy to power cities.
An honourable mention-winning entry in the 2013 eVolo Skyscraper Competition, dubbed Soundscraper, looked into ways to convert the ambient noise in urban centres into a renewable energy form.
Noise pollution is currently a negative element of urban life but it could soon be valued and put to good use. — DesignBuild Source
