Volkswagen flipped a large ceremonial switch yesterday that signaled the official launch of a huge array of photovoltaic solar cells at its Chattanooga assembly plant, which builds the Volkswagen Passat mid-size sedan. The new solar field can supply up to 12.5 percent of the plant’s total...

When it comes to service costs and fuel, everyone knows that electric cars are far cheaper to run than gasoline cars. Even with a plug-in car, however, you still have to pay your local utility company for the electricity used to charge it. Like gas prices, electricity prices are on a steady, upward...

Renewable energy, especially solar, is making inroads into the U.S. power grid, but it's a very slow process. And especially in the wake of the Solyndra collapse, it's one fraught with political wrangling. But there's another country that plans to invest heavily in solar power, hoping to provide...

Electric cars are only as green as the means by which they get their power. While producing zero local emissions and propelled using efficient electric motors, ideally that electricity would be from a renewable source, rather than by burning fossil fuels or even using nuclear. That's not always...

The Sun Cup Challenge sounds like something you might find in a Mario Kart video game, next to the Mushroom Cup and Star Cup, but the reality is much more significant. This year, the Sun Cup Challenge is a competition within the mighty Baja 1000 race, where competitors tackle a thousand miles of...

While solar has its place in the electric car world, it's not yet suitable for powering an electric car directly. A Prius or Leaf may come with a small solar panel mounted in the roof, but that's just to power accessories. And if you want to run your car on solar electricity, your best bet is...

"Yeah, but where does the electricity come from, huh?" comes the oft-sneering question when the subject of electric cars is brought up in polite conversation. Sneery it may be, but there's an underlying point if your main source of power is something like coal. However, BMW ActiveE drivers will...

A southern California Prius owner learned the hard way that energy-efficient building windows can reflect enough sunlight to melt plastic.

So often in the world of Industrial design, form follows function. Then once in a while, a design comes along that turns a mundane object like an electric car charging station into something a little more artistic. Enter the leaf-shaped Lotus solar-powered electric car charging station. Designed by...

Yesterday, GE Industrial Solutions announced the latest in a line of solar-powered initiatives and partnerships designed to help electric car owners power their cars with solar power: a distribution agreement with photovoltaic solar power specialist REC Solar. The agreement, which will see REC...

The University of Michigan team is preparing for the upcoming World Solar Challenge by driving their Quantum Solar Racer on a thousand-mile loop around Michigan.

It's moving from an innovation to a fad, this business of solar-powered charging stations for electric cars. The latest car company to jump on the bandwagon is Mitsubishi, which will launch the diminutive four-door, four-seat 2012 Mitsubishi 'i' electric minicar in November at a price of just...

Mike Koenigs is also a true Tesla and clean power activist

In this day and age, when it comes to being green, looking at the end result is never enough. You have to take a life cycle approach to assessing how green something is, which in the case of cars, means looking at how they are manufactured and delivered to your driveway. Unfortunately, most cars...

You hardly need us to tell you that there’s been an ongoing race to become the king of plug-in vehicles between Nissan and General Motors ever since the two firms launched their 2011 Nissan Leaf and 2011 Chevrolet Volt. But with both cars battling it out on the forecourt both firms can worry...

A green roof is not at its most photogenic in a Michigan winter. In fact, it's hardly green at all--more like gray and brown--though it still insulates the building below just as well. But while some of the green aspects of Ford's showcase Rouge assembly plant have succumbed to the January weather...

Audi is demonstrating the use of solar energy for future mobility by converting the roof of one of its factories in Ingolstadt, Germany to solar panels. Here, Audi e-tron models will in future have their batteries charged with current obtained directly from the photovoltaic equipment installed on...

We've discussed before the issue of how clean electric cars really are when you take into consideration the source of the electricity you use to charge them - they're only as clean as the grid powering them. It's usually one of the first things EV dissenters bring up... "Yeah, but where does the...

Cape Town in South Africa has just hosted the end of a journey of almost 2,500 miles on solar, hydrogen or electric power. The race, the South African 2010 Solar Challenge, was won by Japan's Tokai Challenger, a solar-powered vehicle with a top speed of 100mph which has previously won the 2009...

Pretty much everyone loves renewable energy. The problem is that wind usually blows at night--often sporadically, at that--and solar power is unpredictable. Suppose the secret to harnessing their potential was ... used electric-car batteries? GM said today that it would work with ABB Group to...
