Energy costs money, energy IS money, and the love of money is the root of all evil. What I'm referring to is the naive assumption that wind/solar/green energy will somehow replace CO2 emitting CxHx sources, thus reducing global warming. The problem is a lack of self discipline. You bring on line your green sources and CxHx useage rates won't go down, it will just be more total energy to play with, I know human nature too well. How many people wisely save/invest excess capital vs how many max out credit cards with no hope of repayment? It's like a cocaine addiction, the addict must always have more, more, MORE; instead of self control. Better a dry morsel and peace therein than plenty...with strife......Thus it is laudable that texans are developing alternate energy sources as REPUBLICAN entrepreneuers, but hand in hand must go WISE use of energy. You don't leave a loaded gun in a nursery for children to play with, nor let a 5 year old drive a semitruck on the freeway. What if a fantastic new energy source became available, far beyond the ones you mention? Do you see my point?
