Power Transmission is a Real Problem for Renewable Energy
| August 24, 2010 | Posted by Craig Shields under Renewables - Politics |
I like to post articles on Renewable Energy World, as they have pretty decent traffic among people interested in a wide range of clean energy topics. Today, I commented on Stephen Lacey’s piece Is the Transmission ‘Problem’ Real? in which I indicated that he’s correct: to some degree, the argument that the grid needs to be upgraded in order to accommodate more clean energy is specious.
I go on to mention that I’m more interested in renewables on a national or continental scale. And, while I’m aware that Bill McKibben and thousands of other smart people see a future dominated by individual energy farmers, each, putting his unused electrons back onto the grid, I question whether this adequately addresses the matter of scale. With our growing population of energy-hungry consumers, utility-scale renewables appears to me to be the only way to get this done.
And this is where transmission really is an issue. As we know, renewable resources are localized: the sun shines hottest in the southwestern deserts, the wind blows hardest in the plains, the mountains have the best geothermal resources, etc. A significant upgrade to the grid — preferably to high-voltage DC — is required to make this happen.
Yet, as usual, the difficulty here is almost exclusively political. In particular, we’re being told that, for legal reasons, we can’t have a national high-voltage grid. And unfortunately, the US Supreme Court didn’t help the cause in its recent ruling, either.
I really don’t understand the problem. We have national pathways for the transportation of automobiles, railway cars, natural gas, etc. Can someone provide a reason — other than sleezy politics — that we can’t use our crystal clean eminent domain laws to get this done? There should be nothing new or scary about this.
