Tapping into the Sahara Desert's vast solar power potential (not to mention wind power) seems like a great idea -- and the first solar power project of the massive Desertec project is scheduled to start construction soon. But should concentrating solar

Solar panels i think are a better option

Solar, wind, geothermal, and ocean wave/tide/current are likely to be all there is left when the oil runs out. Will we be connected and survive or will a new Dark Age of humanity depopulate us and leave behind legends of magickal burning rocks (coal and tar shale), lightning-fast vehicles, and trips to the moon?

Well, at least people are looking into this stuff now. Hopefully they will figure these things out soon.

solar and wind - the way to go..... instead of wasting time on nuclear, and war - focus on this stuff governments of the world....

Lets not forget the amount of shadow the solar panels create in a desertic region. This shadow can be used to protect both humans and crops, protecting difficult terrains/crops from to much sunlight and serving local communities for income and export.

I understand why power companies want large arrays, they want us to stay on their grid and pay them. My hope is that we will go very local with solar and wind on homes and buildings, no need to build billions of dollars in infrastructure to move the energy. There are so many great ideas, like solar panels in parking lots...shade the cars, make energy and when we go fully electric with cars....a plug for your car while you're at work or shopping...what could be better than that! In CA an onion processing plant converted to using its organic waste to methane and now they are completely independent, and they no longer need to truck their waste to fallow fields to get rid of it, which used fuel of course, and created a methane problem in those fields. Now THAT is smart! but, of course the big power companies hate that! Thanks for sharing this, Agnes. Love all your articles on renewable energy.

Exactly right Bonnie, No Body (I assume you mean rooftop panels?). In addition to the corporate control point Bonnie makes, absolutely renewables should be subjected to the scrutiny for negative environmental impacts as dirtier technologies. It ain't about cowboys and Indians, white versus black hats; it's about saving the planet and anything that harms Gaia should be avoided as much as possible. And, of course, humans and other living things can live without electricity, but not without water. (However, dirty energy forces will sometimes exaggerate the negatives. Be watchful for that, but not knee-jerk dismissive of possible real problems.) Finally, as in so much of life, as E.F. Schumacher said, small (and decentralized) is beautiful.

Live simply, that others may simply live.

We appear to be on the same wave length, Myron. I do mean rooftop solar panels, or wind if your region is best for that, or windows or curtains, whatever cool stuff smart people come up with. I live in San Diego, and you may have heard about the big blackout in September. The only homes with power in a huge region including AZ and Mexico, were homes with solar panels, in conjunction with storage batteries. One little oops from one guy in AZ and millions of homes and businesses go down. Now THAT's a message for "national security" and decentralization of power if ever I came across one! SDG&E is currently asking for permission to charge solar homeowners who sell their excess back to them a $20 to 30 fee for use of the grid! How's that for a reason to tell these guys (a sub of SEMPRA) take the grid and hey...put it where the sun don't shine! He he.

Storage is often a problem because once people pay for all the tech, they have no money for storage tech and therefore are stuck on the gird. However, I met a man who was working with 3 others on recycling batteries from hybrid cars for use as home energy storage. You see, a car needs over 70% recharge capacity, but that's just fine in a home. There really are lot of people working on things like this and making the tech better...we just need to keep an eye on the big utility companies trying to undermine the work being done. The local chapter of MoveOn I belong to, is keeping an eye on SEMPRA and working with other orgs to put a monkey wrench in several of their shifty plans. You are very right, it's about saving the planet...not for me and you so much as, for my grandbabies and everyone's grandbabies.
