Confronting climate change and poverty, a new crop of city farmers comes of age in Africa. Table of Contents | Digital Edition

I'd argue that plenty of energy (not finance) experts offer some reason to believe that baseload from clean, renewable energy is possible. Talking concentrated solar alone (which many are even referring to as "solar baseload," there are more than a dozen new CSP plants being planned right now in the United States, with some 3,100 megawatts expected to come online by 2012. Just a couple of projects in the works include the 553-megawatt Mojave Solar Park in California, the 500-megawatt Solar One and 300-megawatt Solar Two projects in California, a 300-megawatt facility in Florida, and the 280-megawatt Solana plant in Arizona. This is a far cry from the 75-MW ceiling cited by the interviewee. Wind potential is even greater. By the end of 2007, Texas installed 4.4 GW (Gigawatts!); California, 2.4 GW. By the end of March, Texas had 5.3 GW. This has been driven by the wind tax credit and a strong state mandate. A year ago, the Texas Public Utility Commission approved transmission lines that could deliver up to 25 GW of wind by 2012. This is all just the start and is clearly baseload potential.

I think the interviewee focuses on the dollars and cents (indicated in the original title "$cared to ¢are") of renewable energy equity investment, as opposed to the technical plausibility of the utility projects. And though the market has begun to swing, coal sadly remains the best investment -- in the short-term at least.

I agree that she expresses investors' anxieties with exaggerated pessimism, and the present funding of enormous alternative energy projects contradicts her.

But with her arguable assertions, she plunges an interesting cultural thermometer into a gun-shy financial sector biased against its better judgment.

The logic of convincing environmental concerns has consistently fallen victim to the irrationality of conventional wisdom, especially among the decadent "experts" of Wall Street. This misguided flock -- thinned by self-predation in recent days -- presents a fortunate opportunity for independent investors interested in making money after an inevitable pricing of carbon emissions. Failing to recognize such overarching patterns promises to punish those beholden to a blindly anti-ecological bias.

Finally, and arguably her best point, she bemoans a wasteful culture of consumption and consequently fears future power shortages in this country. This double-edged sword demands both responsible investment -- in SmartPower for greater efficiency and battery technology for better storage -- and universal energy efficiency education, from neo-natal to the nursing home.

Excuse the irony of hogging the share of comments on my own blog, but I couldn't resist quoting our own government on this. Setting aside details of private equity investment, the US Department of Energy explains Photovoltaics and the aspirational baseload:

"PV technology can meet electricity demand on any scale. The solar energy resource in a 100-mile-square area of Nevada could supply the United States with all its electricity (about 800 gigawatts) using modestly efficient (10%) commercial PV modules.

"A more realistic scenario involves distributing these same PV systems throughout the 50 states. Currently available sites—such as vacant land, parking lots, and rooftops—could be used. The land requirement to produce 800 gigawatts would average out to be about 17 x 17 miles per state. Alternatively, PV systems built in the 'brownfields' —the estimated 5 million acres of abandoned industrial sites in our nation's cities—could supply 90% of America's current electricity.

"These hypothetical cases emphasize that PV is not 'area-impaired' in delivering electricity. The critical point is that PV does not have to compete with baseload power. Its strength is in providing electricity when and where energy is most limited and most expensive. It does not simply replace some fraction of generation. Rather, it displaces the right portion of the load, shaving peak demand during periods when energy is most constrained and expensive."
