Renewable energy generates a larger portion of the world’s electricity each year. But in relative terms, solar power generation is hardly a blip on the energy screen despite its long history of technological development.
In this Part I, we review the standard taxonomy of central solar power generating plants by focusing our attention on solar thermal technologies and demonstration projects. The technologies are reasonably well defined yet two formidable hurdles remain: large-scale energy storage technologies and first costs on the order of $5,000/kW, the same cost range as a Generation III+ nuclear plant.
Future posts will explore a number of interesting commercial projects that have either recently or will soon break ground and the latest developments in hybrid projects that combine many of the available solar energy conversion technologies with conventional fossil-fueled technologies.…

Renewable energy, particularly wind and solar, are packaged as “new” and “the energy future.” But on close inspection, as the quotations below will show, these technologies are very old and have had many decades of application.
And as sure as the sun shines, solar and wind fail the economics and product-quality tests as dilute, non-stored, intermittent energy sources. And why amid a boom in fossil fuel supplies–a stock of energy from the sun’s work over the ages–would one chose a far more costly and unreliable energy source from the sun’s weak flow?…

President Obama just returned from Copenhagen empty handed. His hometown will not get the 2016 Olympics, or as a representative of the Natural Resources Defense Council’s (NRDC) Chicago operation advertised it, the “Blue Green Olympics.”
Given the science, economics, and politics of the global warming, aka climate change, it can be hoped that Obama–and the heads of all governments around the world–come away ’empty handed’ in Copenhagen in December. No town, city, province, or country should be burdened with energy rationing when consumer-driven, conventional energy has become more sustainable, not less.
The real global issue is economic recovery and growth, which means expanded private property and enhanced market institutions to promote sustainable growth in place of abject poverty and economic underperformance.…
