Geothermal power development has traditionally been about drilling down into subsurface reservoirs of hot water. Enhanced geothermal is expanding the field to include dry, permeable hot rock where water can be added.
One thing sure to help the continued expansion of automotive innovation that focuses on greener outcomes is continued public/private partnerships.
Wind power generation in Texas continued its steady upward march in 2013, and it’s now on the doorstop of 10 percent of the state’s electricity supply.
They’re calling it the “world’s largest solar powered bridge,” and who’s to argue? We haven’t seen a bigger one than 4,400-panel-covered Blackfriars rail bridge that spans the Thames in central London.
Many U.S. cities are taking steps to grow urban centers in an attempt to reduce greenhouse gas emissions. But a challenge is the significant carbon footprint of spacious suburban living, which in many areas, may be cancelling out these efforts.
Security, predictability, climate change, safety – all of these are cited by the U.S. Department of Defense as motivating factors for its embrace of energy-efficient and renewable technologies. But a new report from the Pew Charitable Trusts puts just as much emphasis on another factor that might come as a surprise: cost.
There’s no technological challenge to flying commercial airliners on fuels with a substantial renewable component. It’s been done, done and done again.
Zero net energy, once a wild-eyed, seemingly unattainable vision, isn’t exactly mainstream, but the concept is definitely taking root in North America: A new report says the number of buildings either at or reaching for the standard has more than doubled in the past two years.
Who’s the rising star in U.S. solar? It’s North Carolina. The state isn’t quite challenging California as the U.S. leader for solar development – the hugely populous, sun-splashed Golden State is most likely a permanent fixture at No. 1. But North Carolina appears to be nosing past the likes of Arizona, New Jersey, Nevada and Massachusetts to claim the No. 2 spot.
As work to make solar power more efficient and affordable proceeds – important work that can boost solar’s share of the electricity we consume – some scientists are off on an entirely different research path. This is the effort to turn sunlight into fuel.
BYD continues its plot for world domination of green vehicle technologies, mostly seen in the mass transit sector, with the recent unveiling of a new plug-in hybrid “intended to target key world markets.”
A new plug-in hybrid concept car debuted from Audi this week at the Detroit Auto Show that is described initially in just a few simple words – sporty, compact and versatile. Whether or not this is actually the case for the new allroad shooting brake car remains to be seen, but it does impress with its green vehicle specifications at the least.
Flow batteries – more akin to fuel cells, really – are getting increasing attention as researchers press to meet a need for energy storage brought on by the rise of intermittent renewable sources like solar and wind.
Daimler’s small city car brand smart has unveiled a new model known as fortwo edition citybeam that is available in an electric only option. The price of the zero emissions option offering will run over $27,000 at start (over $31,000 for a convertible), and does not include a monthly battery rental fee.
When it comes to biofuels, corn leads the all-important category of biomass yield. However, focusing solely on yield comes at a high price. In the current issue of the Proceedings for the National Academy of Sciences, Michigan State University researchers show that looking at the big picture allows other biofuel crops, such as native perennial grasses, to score higher as viable alternatives.
Tesla Motors, already dealing with a public relations issue related to some of its Model S electric sedans catching fire last year, now has another hot under the collar technology problem to deal with that this time is centered around some of its in-home wall chargers. This new problem reportedly has led to some severe overheating, among other concerns.
issan this week announced pricing for the American edition of its 2014 all-electric Leaf. The car, which will be available in three trim levels, set all time sales records last year and its expected to have a repeat performance for this go around.
That renewable energy “first” that way back in April we said was on its way? It’s here. Power from a geothermal plant in northern Nevada is flowing to Southern California.
The Silicon Valley gives birth to many innovative green technology ideas, and now one of the latest is the rather unique Onewheel, a “self-balancing electric skateboard that lets you fly over pavement on only a single wheel using self-balancing technology.”
Renewable energy critics harp on the variability of wind and solar production, suggesting (or pretending) that this increasingly manageable challenge is some kind of fatal flaw.
