Give people the power to live a greener lifestyle

--Craig Boundy is UK CEO of Logica. The opinions expressed are his own.--

Recent research by Logica showed that only 22 per cent of individuals feel the onus is on them to deliver a sustainable future. Individuals want more guidance on how to live a more sustainable lifestyle, with 18 per cent of respondents saying they had no idea what changes they need to make, and only 22 per cent feeling a responsibility to take the initiative. Central and local government need to put the power into consumers’ hands by equipping them with the knowledge and the technologies to make change a reality – and ultimately to get them excited about living a greener lifestyle.

How many politicians does it take to NOT change a light bulb?

July 13, 2011

Some stories, no matter how serious, are just joke-prone. So it was this week with the proposed U.S. BULB act, which aimed to repeal light bulb efficiency standards that became law in 2007. Sponsored by Joe Barton, a Texas Republican congressman, the BULB bill failed to receive the two-thirds vote of those present in the House of Representatives that would have been needed to suspend House rules and pass the measure.

Starting big, thinking small in batteries

May 12, 2009
Carmakers and regulators look at the adoption of electric vehicles, which draw their power from the electric grid rather than engines and thus emit no carbon dioxide from their tailpipes, as a necessarily gradual process, limited by battery technology.
 
But General Electric thinks its new battery technology, based on sodium, could radically speed up that process.
 
“The way the roadmap has been laid out as I’ve seen it is a lot of evolutionary steps,” with technological development taking years if not decades to replace traditional gasoline powered cars with hybrids, followed by plug-in hybrids, followed by pure electric vehicles said Glen Merfeld, who runs the chemical energy lab at GE’s global research center in Niskayuna, New York.
 
The reason for that long timeframe is that current battery technology limits the range of a car that draws its power solely from an internal battery.
 
“The sodium battery is potentially disruptive to that evolutionary look,” Merfeld said. The technology that we are commercializing will solve some of those problems.”
 
GE on Tuesday said it plans to build a new factory outside Albany, New York, where it will initially focus on producing sodium-metal halide batteries for railroad locomotives. That technology differs from the lithium-ion batteries being developed for the next generation of hybrid autos in that it is better suited for releasing small amounts of energy over time, rather than a lot at once.
 
Eventually, by pairing the sodium battery with a lithium-ion one, such as those made by A123 Systems, which GE owns a stake in, the company could design a power train for an all-electric car that would allow a range of hundreds of miles and cost 30 to 40 percent less than a single-battery power train, Merfeld said.
 
“You’d probably want to start with larger (vehicles) because that’s where you need to store more energy than in the smaller ones,” added Mark Little, a GE senior vice president who runs its research center. “We could imagine a day where you could go to the future and have a small lithium-ion system for the power side and a larger sodium battery for the energy side. But that will take some time to get to.”
 
 
 

Long payback takes shine off LEDs, at least at home

April 1, 2009

Thinking about making your home more energy efficient by installing hyper-efficient, long-lasting LED lighting? Not so fast.

How much electricity do you use in a year?

January 16, 2009

It was a disarmingly simple question but, embarrassingly, I didn’t have a clue when first asked that 18 months ago. Even though I’d have to describe myself as a genuine tightwad when it comes to expenditures, I simply had no idea, strangely enough, about how much money my four-person household was spending on electricity — nor how much carbon dioxide was being produced.

Germany’s ‘Sun King’ Asbeck explains solar power for Vatican

December 11, 2008

Every once in a while you run into someone with so much energy that you find yourself wishing you could plug something into them to tap a bit of that excess power. On a dark, cloudy December afternoon, I spoke to Frank Asbeck, the chairman of SolarWorld and dubbed the “Sonnenkoenig” (Sun King) by a leading newspaper in his native Germany for turning an idea (mass use of photovoltaic) into a multi-billion euro corporation with 2,500 employees — in little over a decade.

How many jobs does it create to screw in a lightbulb?

October 21, 2008

Change to an energy-saving lightbulb – create a job? lightbulb.jpg

Energy efficiency efforts in California over the past three decades have created or saved 1.5 million jobs and added $45 billion to payrolls in the state, according to a report from David Roland-Holst of the Center for Energy, Resources and Economic Sustainability at the University of California, Berkeley.

A Silver Bullet or just ‘Greenwash’?

September 9, 2008

A truck with a CO2 tank stands in front of the mini plant “Schwarze Pumpe” before the first official run in Spremberg SeptemberCan carbon capture and storage (CCS) save the world?

Is this the silver bullet everyone’s been waiting for? Or just pie in the sky? Is capturing and storing carbon dioxide the technology breakthrough to cut greenhouse gas emissions without getting in the way of economic growth and industry’s “addiction” to fossil fuels? Or is it just a “greenwash” — a token gesture by some of the utilities responsible for so much of the world’s CO2 to try to persuade an increasingly green public that the great emitters are doing something to fight climate change?
