In the real world, solar often gets barely a passing grade

On September 18, 2007, in Blog, by Neal Dikeman

I’m a big fan of solar power. But as with anything, I like to know exactly what I’m getting. One of the big unspoken issues in the solar sector is the difference between the rated or estimated potential output of a solar system–and the actual production of kilowatt-hours. A range of factors from the margin […]

Reflections on Energy Policy

On September 17, 2007, in Blog, by Richard T. Stuebi

by Richard T. Stuebi At the beginning of my career in the mid-1980’s, I participated in numerous economic analyses pertaining to the “acid rain” debates that were then raging in DC.

The Problem With Polls

On July 23, 2007, in Blog, by Richard T. Stuebi

by Richard T. Stuebi Recently, I’ve been working more closely with people who are active in setting and shaping policies, and it’s clear that they’re wired differently from me. As an economist, my first question in considering policy usually is: “What are the costs and benefits?”. The policy-wonks tend to first ask: “What do the […]

On July 9, 2007, in Blog, by Richard T. Stuebi

by Richard T. Stuebi I reckon that relatively few readers have heard of the company called Preformed Line Products (NASDAQ: PLPC). I know I hadn’t, even though their headquarters is just a few miles from where I live in suburban Cleveland. A couple of months ago, I came across a press release indicating that PLPC […]

by Nick Bruse One of the most exciting aspects of the cleantech/sustainability sector are the opportunities presented to create completely new industries over the coming years.

The cleantech sector received a huge boost this week from the news that Portugal’s EDP anounced the acquisition of Texas based Horizon Wind for a price of over $2 Bil. EDP operates globally in Spain, Portugal and Brazil. One of the intriguing aspects of this deal is the history. Horizon Wind was formerly Zilkha Renewable […]

Will Small Wind Get the Love that Solar Has?

On March 2, 2007, in Blog, by Neal Dikeman

Investment and growth in the cleantech sector has been driven in the last 2 to 3 years by the solar photovoltaic, large scale wind, and ethanol sectors. For years solar PV has, on a per kw basis relative to other technologies, received massive rebates and tax credits that underpinned its growth, and large scale wind […]

Turns Me Off

On February 28, 2007, in Blog, by Heather Rae

by Heather Rae I drove along a dirt road to a place in the woods where the plow had left a berm of snow. Sasha, the cocker spaniel, and I continued on foot along a path, crunching through the ice-caked snow. The natural and architectural beauty of Sheepscot, Maine Hollywood could not hope to imitate.

RECs and Carbon Credits are a GOOD Thing

On February 27, 2007, in Blog, by Neal Dikeman

RECs and carbon credits are a GOOD thing, so stop bashing them. As an example a few months ago Inside Greentech had an article attacking renewable energy credits, singling out one such purchase by Wells Fargo, and comparing them to the indulgences sold by the Catholic Church to save your soul in the middle ages.

A (Re)Birth for Offshore Wind

On February 26, 2007, in Blog, by Richard T. Stuebi

by Richard T. Stuebi In the early 2000’s, much of the interest of the worldwide wind energy community was focused on offshore opportunities. This was because the world’s largest wind market — Europe — was getting developed towards saturation, and the best wind resources were offshore where population density was not going to be a […]

The more things change…

On February 21, 2007, in Blog, by Heather Rae

by Heather Rae My favorite book on clean energy is Energy for Survival: the Alternative to Extinction written by Wilson Clark and published in 1975. I was barely in high school then. It wouldn’t be for another 20 years that I would hear the words ‘compact fluorescent bulb’ and another 28 before I would discover […]
