In Clean Tech Revolution, the authors give a compelling case for investing in new energy technologies. Environmental concerns are giving way to economic incentives. Investment includes time and work in addition to money. That's good, since time is all I have to offer.
One of the points in the book is that the energy grid will change from being a one-way system, from utility company to houses, to a two-way web much like the internet. Energy will be consumer generated.
How will energy ownership work? Will it be an open commons of electricity? Will it chart borrowing and loaning by volumes of KWs? If all the energy is integrated, will corporations be able to own sectors of the grid the way telecommunication giants control current wireless networks?
Either we'll end up with socialized electricity, or we'll have to pay corporations for the right to use energy produced from our own rooftops. There'll certainly be other economic models. And they'll certainly be bought or forced out by the most successful competitors, and those will be the most aggressive.
Somehow, I don't think we have a shot at free or even substantially cheaper energy. The technology is there, the infrastructure will soon be in place, and the natural resources are limitless. But, there are simply too many business minds churning out new ways to privatize the sun, air, and water that sustain us.
