In his inaugural address President Barack Obama reinforced his commitment to a new "green" energy future for America. He has stated that this will be strongly reliant on solar and wind as major, if not predominant, sources for electrical energy in our future. In his vision this transformation of the basis for modern industrial life will occur in less than a decade. I cannot see how this transformation can occur scientifically and industrially much less socially and politically. Currently power is supplied to the user grid from what one may term power plants. These are large facilities that generate power from fairly large generating machine systems. There is much efficiency in this approach as the physical footprint of the system is smaller and maintenance and repair are more efficient as the necessary personnel are at the point-source sites. These sites serve as hubs in a power supply grid designed, owned and maintained by the companies involved. These are generally coal fired, water power or nuclear powered. We are apparently now offending Mother Gaia and dooming the world to massive sudden global warming by continued use of these methods.
Enter the new age of wind and solar power. I admit I am somewhat behind on my reading, but I missed the massive increase in our industrial capability of building hundreds of thousands, if not millions of smaller wind and solar installations. This is the only possible solution, as large solar and wind "farms" can only be constructed in certain areas. Given the NIMBY syndrome, most of us would not want these in our pristine locals. We certainly cannot put them on federal lands since we can't drill for oil in a few acres of ANWAR, much less have hundreds of square miles of wind and solar farms in the wilderness or off the seacoast.
Thus the "personal power plant" with solar panels on your roof and a windmill with a 200 foot tower on your back yard. Who pays for these and maintains them? The solar panels have an initial cost of $30,000-$80,000. Despite assurances, they are not maintenance free. Who pays for the repairs? What if you generate more power than your needs? What if you generate less? What about the massive multistory condo or apartment that sucks energy like a thirsty camel to run all those TVs and internet?
Ideas in the absence of a full understanding of their consequences can be be expensive and chaotic.
