Got a Prius? Got spare parts and some extra time?

Auto engineers, like everyone else, need things to do in their spare time to keep themselves amused. If you are part of Toyota, this might mean you belong to the Toyota Engineering Society (TES). And if you belong to TES, you are likely using parts from the brand to build, say, a Prius like plug-in hybrid roadster on steroids.

Vertical urban gardening hits new heights

Patrick Blanc might have invented vertical gardens, as he claims, or perhaps he simply popularized an earlier concept, as editors at Wikipedia confidently attest. In any case, Blanc is the reason these “green walls” are popping up with increasing frequency, so there’s nobody better to explain what it is they bring to the world.

New technique makes "biogasoline" from plant waste

Gasoline-like fuels can be made from cellulosic materials such as farm and forestry waste using a new process invented by chemists at the University of California, Davis. The process could open up new markets for plant-based fuels, beyond existing diesel substitutes.

Toyota unveils new hybrid racer

Toyota, ahead of the forthcoming 2014 FIA World Endurance Championship season, has announced plans to enter a new car this year to take part in events like the Le Mans 24 Hours.

Honda's Micro electric car is going solar

Honda, which unveiled in Japan this past November a micro electric car undergoing urban field trials, has now added an option to allow the MC-β to be powered via solar energy. Rather then directly sporting its own solar panels, like this Ford plug-in hybrid concept, however, it will instead get charged cleanly at a special solar panel equipped recharging station.

Expanding wind power's reach with taller turbines

Wind power is pretty easy to do in the gusty Great Plains, and through passes and other breezy corridors in the mountainous West – and that’s where the fast-growing renewable energy source has made its greatest strides.

Is Obama an energy realist?

We saw an interesting evolution of Barack Obama as an energy president on display earlier this week in his fifth official State of the Union address. You might say the president got real.

Solar takes the lead as wind lags in 2013 (US) installs

The first look at comprehensive data on energy generation infrastructure added in the United States in 2013 shows a big jump in solar, a massive decline in wind, and natural gas dominant.

How to control EV charging costs

What is the optimal way to charge electric vehicles that will keep the costs associated with electricity down? Researchers at Carnegie Mellon University may have found one possibility, optimally varying the charging speed of plug-in electric vehicles to cut the electricity cost in half and make it ultimately much more affordable to own one of these forms of green transportation.

Icelandic magma marks geothermal heat milestone

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.

DoE wants fuel effcient American vehicles

One thing sure to help the continued expansion of automotive innovation that focuses on greener outcomes is continued public/private partnerships.

Texas moves forward wind power

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.

This bridge is covered in solar panels

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.

Report: Suburban sprawl accounts for 50 percent of US household carbon footprint

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.

Solar energy helps the military save

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.

Boeing moves forward with biofuels

There’s no technological challenge to flying commercial airliners on fuels with a substantial renewable component. It’s been done, done and done again.

Report: Zero net energy is here

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.

Solar goes FTW in North Carolina

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.

Scientists eye sunlight-to-fuel goal

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 unveils Qin plug-in hybrid

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.”
