This Energy Insights post comes from a recent Intechange podcast Steal This Decarbonization Plan! with Hal Harvey, who is talking about his excellent new book Designing Climate Solutions: A Policy Guide for Low-Carbon Energy
- stable, long term goals that don’t rely on repassing legislation
- rates of change, not fixed targets
- prices where consumers are price sensitive (i.e. industry)
- don’t set prices - use reverse actions to auction the subsidy
- performance standards where consumers aren’t price sensitive (i.e. transport)
Divergent learning curves
Figure 1 - The costs of solar photovoltaic modules have decreased apace with deployment - Figure 2.1 from Designing Climate Solutions: A Policy Guide for Low-Carbon Energy
Harvey defines a learning curve as how fast prices drop as volume increases.
Interestingly, Harvey notes that while component costs in solar and batteries have reduced significantly, much slower progress has been made on system prices. There is also variance in system costs across regions - with Germany being half of the US!
Methane - the quick fix
Methane leaks are a large and immediate climate change problem - a leak of only 3-4% makes gas as bad as coal! It’s also an easy fix - it’s a plumbing problem.
Better than batteries
While storage will be crucial in the decarbonization journey, interconnection and demand side response as seen as quicker wins.
Interconnection is especially effective if the grids are already physically connected, and the only work needed is to interconnect the markets.
