Barriers to Solar Energy's Blockbuster Promise

Nice level-headed article on the state of solar photovoltaics (PV) today. I know I get antsy sometimes with respect to PV and want it now and want it cheap. But there are some other positive renewable energy technologies out there that are inexpensive and overlooked. Yes I want solar panels on every house in the Denver metro area, but at what expense to the market and to the consumer? Silicon production is not up to speed and today cannot meet the entire demand for PV. Tax credits may expire at the end of this year. The public hasn't been educated enough on the use of renewable technologies in the home. And legislation is all over the map, state by state. I know this will work itself out, as there are many intelligent and passionate people studying and working on these issues in every state. Bottom line is that we (me!) need to have some patience while consumers; private enterprise; and local, state, and federal governments work out some smart renewable energy policy.
