Why do I get the feeling that they are just going to subsidize electricity costs using general government revenue?

The root of the problem is that, for almost 14 years now, the government has been signing tons of poorly written and poorly thought out contracts.  They signed guaranteed deals with a huge number of electricity generators, often for power we don't even need, all in a vein attempt at proving how "green" they were.  In order to overpay for a multitude of solar and wind generating capacity they were forced to also overpay for natural gas fired capacity to be there for the times when the wind wasn't blowing.

Unfortunately there is very little that this, or any, government can do to get out of those contracts.  They can talk about "smoothing out" the contracts but that won't CHANGE the contracts, just subsidize the costs today at the expense of higher costs in the future (and by "future" I mean "after the next election").
