The scoring scheme should not be taken too seriously. Abundance is more important than whether something is backyard-compatible, for instance. Yet devising a weighting scheme struck me as adding unwarranted complexity and perhaps even increasing the subjectivity of the exercise. If you are so motivated, generate your own weighting scheme and change box colors while you're at it. Post it on a blog! Treat us to your biases.
Rather than fostering infighting among renewables, I hope the main points are not lost: that fossil fuels are qualitatively superior on the matrix categories, and that transportation without fossil fuels will be hard. The world is not static, and neither is the matrix. Reds can become yellow and green, with development. Greens could become yellow with depletion, etc.
