1) The sun doesn't compete directly with oil (at least, not all that much)
2) Electricity prices are still going up
3) Solar prices are still going down (some analysts predict a further 40% fall in solar prices in the next 2 years!)
4) Sales of plug-in vehicles are doing just fine (I told you so!)
5) Pump prices haven't dropped as much as oil prices (partially because other countries are doing what we should be doing—raising gas taxes and cutting fossil fuel subsidies while oil is cheap)
6) Oil prices won't stay this low forever
7) Global investment in clean energy keeps flowing
