Since diving into the deep end when it comes to energy issues, almost every day sees new fascinating concepts, approaches, and technologies.  Fascinating ... exciting ... even hope inspiring at times.  And, as well, as the passion builds, so many of these are truly Energy COOL.  

One of the most powerful images for a renewable energy future, a burning hot one we might suggest, is TREC, which is a grand vision for connecting solar power in North Africa, wind power from the Eastern Mediterranean to the North Sea, bio-mass, and hydropower with a high-voltage direct current (HVDC) system of power lines to provide assured renewable electricity for the Mediterranean basin and Europe.

This concept, which has seemed ever so Renewable Energy COOL to me from the first time I encountered it, looks to be moving down a path from fantastic innovative concept to potential reality as Europe is heading toward an initial investment of $10 billion dollars in DESERTEC.

According to a recent Guardianarticle,

Europe is considering plans to spend more than £5bn on a string of giant solar power stations along the Mediterranean desert shores of northern Africa and the Middle East.

More than a hundred of the generators, each fitted with thousands of huge mirrors, would generate electricity to be transmitted by undersea cable to Europe and then distributed across the continent to European Union member nations, including Britain.

One of the benefits of this, the HVDC, is to help cover the intermittency challenges of, for example, wind power by linking with very low transmission losses wind in the Mediterranean to North Sea wind. And, distant hydropower stations used for pumped hydro storage. And, the extended distance east-to-west of the solar plants connected in the grid would extend, in essence, the "day" in which the grid would be directly collecting solar radiation. (And, the CSPs would store heat to enable power generation after sunset.)

Billions of watts of power could be generated this way, enough to provide Europe with a sixth of its electricity needs and to allow it to make significant cuts in its carbon emissions.

This is an amazing conception, a path for making reality of dreams for lighting our lives with the sun.

At the same time, the stations would be used as desalination plants to provide desert countries with desperately needed supplies of fresh water.

The benefits are, as suggested here, multifacted. Regions of the world signficantly short of water (even drinking water) would get significant new freshwater supplies almost as what we could call a 'by-product' of the primary product ... clean electricity.

Trans-Mediterranean Renewable Energy Cooperation (TREC) will not be a small project. The rough estimate: £200 ($US 400 or so) billion investment over a 30 year period.  And, at the end of the day, the kilowatt hour cost for this electricity could likely be more than today's coal electricity; that is, more expensive than coal-electricity that does not consider "external" costs of pollution.

The concept is to build 1000 concentrating solar power (CSP) plants on "cheap" land in North Africa.  

The massive construction program, the need for maintenance workers and operators, renewable energy for their economies, and the fresh water supplies  all point to great benefits for North Africa from seeing DESERTEC bloom into reality.

Systems of Systems

DESERTEC is appealing on many levels. In addition to the low (non) carbon electricity, water supplies, and economic benefits, consider these points:

  • Shaded areas under the mirrors of CSP plants are protected from the full glare of harsh tropical sunlight and may be used for many purposes, including horticulture using desalinated sea water.

  • Reduced tensions arising from shortages of energy and water.

  • Improved relations amongst people in EUMENA via a collaboration that yields benefits for all. This is a positive alternative to the confrontational policies of recent years.

While DESERTEC's electricity would likely be more expensive than simple coal-fired electricity without any "external costs" (costs external to the contract, like CO2, mercury, and particulate pollution), with DESERTEC it looks like we should be speaking of external benefits and seeking to incorporate those benefits into the cost just as we seek to incorporate polluting (and other external) costs to the costs of fossil energy use.

Could DESERTEC be a path for changing North Africa's trajectory and offering economic progress and opportunities across the region?

Might it be a tool to help change the direction of the "Global War on Terrorism" through creation of hope and economic opportunity?

Could the greening of areas around CSP plants in North Africa lead to the regreening of North Africa and, even more optimistically, start to lead to North Africa as a carbon sink with newly flourishing green zones?

Just the briefest of overviews

This discussion is, of course, only the briefest introduction to TREC. For years, this has been in the Energy COOL category for me. The discussion of $10 billion in coming investment suggests that others might find this Energy COOL as well. And, well, that perhaps this is an Energy COOL concept that might merit bringing over the pond as part of the Americas' move away from a carbon-energy society toward an Energy Smart future.

We can all help make


Energy Smart.

You must add at least one tag to this diary before publishing it.

Add keywords that describe this diary. Separate multiple keywords with commas.

More Tagging tips:

A tag is a way to search for this diary. If someone is searching for "Barack Obama," is this a diary they'd be trying to find?

Use a person's full name, without any title. Senator Obama may become President Obama, and Michelle Obama might run for office.

If your diary covers an election or elected official, use election tags, which are generally the state abbreviation followed by the office. CA-01 is the first district House seat. CA-Sen covers both senate races. NY-GOV covers the New York governor's race.

Tags do not compound: that is, "education reform" is a completely different tag from "education". A tag like "reform" alone is probably not meaningful.

Consider if one or more of these tags fits your diary: Civil Rights, Community, Congress, Culture, Economy, Education, Elections, Energy, Environment, Health Care, International, Labor, Law, Media, Meta, National Security, Science, Transportation, or White House. If your diary is specific to a state, consider adding the state (California, Texas, etc). Keep in mind, though, that there are many wonderful and important diaries that don't fit in any of these tags. Don't worry if yours doesn't.
