A Balanced Energy Portfolio

What is that anyway? A "Balanced Energy Portfolio?" It sounds so good! It sounds so rational, so reasonable, so measured, safe and deliberate. But what is it beyond a truely brilliant phrase?

It means whatever you want it to mean.

Cats would say a well-balanced energy policy (for people) would focus:

50% on Supply Side stuff like this:

• 75% on Solar Energy
• 15% on Geothermal Energy
• 5% on Tidal Energy
• 5% on Nuclear Energy
  

50% on Demand Side stuff like this:

• 40% on Transportation Energy Efficiency
• 30% on Building Energy Efficiency
• 10% on Industrial Energy efficiency
• 20% on Research into benign restrain wasteful consumerism
  

What would you want it to mean?
