Gary, spot on.

Please add to your list:

- Want to cut down on energy consumption? Here's a tax break on home insulation, solar thermal, PV, wind and geothermal installations (and rain-water harvesting, for different reasons).
- Want to install wind turbines, but it doesn't make sense because you live in a city? Here's a tax efficent fund for people to invest in pre-permitted offshore wind farms with domestic electricity comsumption offset against pro-rate production.
- Road Tax? Replace with a miles-driven scheme calculated according to the emissions of your car, lower emissions, oower rate per mile.
- Remove (or at least reduce) fuel duty on properly renewable fuels (recycled vegetable oils, jatropha-biodiesel, etc)

- the list is endless

The problem with subsidies is that they encourage irrational activity and miss many better options.  If you get paid to install wall insulation and solar heat but not windows, when your major problem is leaky windows, the money will be mostly wasted.

Energy taxes are THE market solution.  They give certainty and reward EVERY successful method of savings.
