Paying for what we want

“One of the problems in the United States is that we haven’t been willing to confront the tough questions,” said Paul Gipe, who sits on the steering committee of the Alliance for Renewable Energy, a group advocating energy policy reform.

“We have to ask ourselves, ‘Do we really want renewables?’ ” he said. “And if the answer to that is yes, then we’re going to have to pay for them.”

This was the closing of today’s NY Times piece titled “Cost of Green Power Makes Projects Hard to Sell.” Written by Matthew L. Wald and Tom Zeller Jr., this article discusses how a few additional cents on an individual’s monthly electric bill are being used to argue against increased renewables for electricity generation in the United States.



Vampires – they’re not just out at night

October 27, 2010 2 comments

You may have turned off your TV, unplugged your cell phone from its charger, and clicked off the radio you were listening to as you left the house this morning – but chances are that they did not stop consuming electricity while you were away. According to the Department of Energy standby (or “vampire”) power is responsible for 5 to 10 percent of residential electric bills in the United States, costing consumers approximately $4 billion per year.

But, according to a Green Blog post in the New York Times, new developments in nanotechnology might revolutionize the very device that is responsible for this slow bleeding away of power – the transistor. I.B.M, in partnership with several European companies, is looking to redesign the transistors found in many of our consumer electronics.

If their plan is successful…

…we could have “cellphone batteries that last 10 times longer than today’s models, and computers and other devices that use virtually no power when in stand-by mode”.

This would be quite an accomplishment, both from a consumer standpoint (no more mid-day charging of cell phones) and from an energy efficiency point-of-view. Eliminating 5-10% of residential electricity consumption could translate into large economic savings, through not only smaller electric bills in the short-term, but also by reducing the need for new power plants in the long-term.


In Fuel-Efficient Auto Contest – Gasoline trumps Electricity

September 20, 2010 1 comment

The Edison2 Very Light Car won the prize for best “mainstream” car in the Progressive Automotive X Prize – while I would argue against its merits in the style department, the 100 mpg rating it boasts is pretty sweet.

The first Progressive Automotive X Prize was a one year race to design fuel-efficient cars that are “safe, affordable, and desirable” that ended last Friday. As reported in this NY Times piece , the competition produced a group of finalists with vehicles that could achieve 80, 100, or even 180 miles-per-gallon, while still looking stylish (at least to the designer) and being affordable.

The winner of this competition might surprise you because it wasn’t an all-electric car produced by one of big guys – that is Ford, Chevy, Toyota and their cousins – but instead was a gasoline-powered vehicle created by Virginia-based company Edison2, running on E85 (a blend of 85% ethanol and 15% gasoline).  The “Very Light Car” gets about 100 mpg and had the lowest carbon footprint of the cars in the competition. While I am personally not a fan of the car’s style, 100 mpg does sound pretty great.

According to David Friedman, Director of the Clean Vehicle Program at the Union of Concerned Scientists, it is energy density that led to the Very Light Car’s triumph. The high density of energy in gasoline (or in this case gasoline/ethanol blend) has made it the king among transportation fuels – because, what fun is driving if you have to fill up every 50 miles?

More to come on the concept of energy density in future posts…

So, why do we care about fuel-efficient cars?

Money… air…. water… money….

About 2/3 of the petroleum used in the United States is dedicated to the transportation sector – our cars, buses, planes, and trains – which currently runs almost exclusively on this fossil fuel. Today, we require that the gasoline used to power a large portion of this sector be blended with ethanol, a biofuel derived from corn (at least in this country). But, this has done little to curb our total petroleum consumption.

Interestingly, the same fraction (2/3) of the petroleum that we use is imported from other countries.

With concerns about the economics and environmental impacts of our transportation sector, the efficiency of the transportation has gained focus – resulting in hybrid electric vehicles like the Toyota Prius and electric-only vehicles like the Chevy Volt and Nissan Leaf. The Progressive Automotive X Challenge was designed to bring the industry another leap forward. While I’m not sure it achieved that goal (i still can’t picture myself driving a Very Light Car down 6th street), the spirit behind the competition is still a great one… and maybe the $5 million prize will act as a good catalyst to push us into the future.
