James Crabb Posted over 1 year ago What is the intersection of renewable energy and an individual person? I was thinking as I read the latest interest about Ivanpah that there is an "efficiency" that is often ignored in renewables. Its space-efficiency. (http://www.ted.com/talks/david_mackay_a_reality_check_on_renewables.html) If we have to sprawl our renewables (more wind turbines in the prairie, more solar concentrators in the desert) for every given amount of urban sprawl... then we are bound to make the problem worse, not better (at least in terms of land use). So there is some logic to what you are saying - That we need are as many structures as possible with an energy surplus. ...But how?
