Clean, cheap long distance electricity transmission? Worth investigating.

I recently stumbled upon some High Voltage Direct Current (HVDC) technology that seems promising to me for long distance transmission. It is not existing technology; it is a detailed proposal with no prototype and not even a computer simulation behind it. Nonetheless it looks like a less expensive and more environmentally friendly way to move […]

CDM study defending CDM against charges of being a miserable failure is a miserable failure

My last post was a reminder that the Clean Development Mechanism(CDM) remains a miserable failure. The evidence that it does not actually contribute to solving the climate crisis included data that showed that the overwhelming majority of offsets certificates issued and approved by the program are generated by scandal ridden projects, and are widely acknowledged […]

Colorado to achieve 30% renewables 8 years early, ratepayer savings of $409 million

Advocates say that massive amounts of renewable energy are feasible and will save money in the long run. But how do we know that’s true? Because that’s exactly what’s happening.  Let’s take Colorado. The state has a 30 percent renewable energy requirement. How are things going? Xcel, the largest utility in the state, says it […]

CDM still a miserable failure

Since there seems to be resurgence of attempts to defend the Clean Development Mechanism (CDM) offset system, it seems time for a reminder of how badly the idea has failed. The fundamental idea behind CDM is that greenhouse gas polluters in rich nations could continue to release greenhouse gases, but pay polluters in poor nations […]

Is the pipeline victory a turning point for the climate movement?

Two days ago, I was convinced that the amazing Keystone XL pipeline victory won by the North American climate movement on Nov. 10 was going to be, without question, a pivotal turning point. Today, having thought more about it, I’d say it’s more like somewhere between “maybe” and “probably.” I’m reminded of another “victory” that […]

Friday music blogging: Portugal. The Man (exclusive world premiere videos!)

The annoyingly punctuated Portugal. The Man is a psychedelic rock band originally from Wasilla, Alaska, home of … oh, what was that crazy lady’s name again? They made their way down to their current home, Portland, Oregon, in the mid-2000s and have been cranking out albums ever since, gathering momentum and popularity along the way. […]

Using Sustainable Water to Plan for the Next Billion

Last week, Danica May Camacho of the Philippines became the world’s symbolic seven billionth person. The occasion drew mixed feelings in the policy world — what does a booming global population mean for climate risks? To cite one issue, leaders are worried about the declining supply of water in regions vital to economic growth. This isn’t […]

California study is NOT about technological limits. Why glass is 100% full

A recent state sponsored study shows that California could reduce its greenhouse gas emissions 60% compared to 1990 by 2050 with today’s technology(pdf).  That has sparked a debate.  The glass-half-full crowd, among whom I usually count myself would argue that if we have the technology today to achieve a 60% reduction, if we start implementing […]

Another Congressional Attack on Clean Air

Why should you care about the Cross State Air Pollution Rule? Because it could save your life, or the life of someone you love. Congress is continuing its attacks on clean air this week, and the latest target in their crosshairs is the life-saving Cross State Air Pollution Rule. This clean air safeguard would require […]

Solar Industry Executives Talk About Massive Solar Jobs Growth

In mid-October, my Tigercomm colleague Mark Sokolove and I took Scaling Green’s Communicating Energy lecture series on the road to the Solar Power International 2011 (SPI) conference and trade show in Dallas, Texas. With so many articulate, knowledgeable, clean energy thought leaders and company representatives in attendance, the opportunity to interview several of these folks on the state of the solar […]
