There do exist large subsidies for remote installations, it's called the Renewable Remote Power Generation Program

"Rebates of up to 50 per cent of the capital cost of renewable generation and essential enabling equipment are available to applicants that fully comply with the eligibility requirements and procedures outlined in the RM sub-program guidelines. The maximum rebate available is $200,000."

WA, Tas and NT have their own state programmes administered separately to this federal one.

As I understand it, the RRPGP was budgeted with a certain amount of funds; when they run out, the thing is over. The Department of the Environment has privately stated that the programme has "only a matter of months" before it runs out of funds. First come, first served.

I think it's useful to know that when it comes to renewable energy, the government rebates are always going over-budget due to high demand. That tells us that there is a strong demand in the community for renewable energy, but that price is the major obstacle. If by public subsidy, carbon taxes, economies of scale or whatever we can get the prices of conventionally-generated and renewably-generated energy to match, people will take it up.

I don't see why we shouldn't. In the Western world we worked for a century on getting food prices down, taking them from one-third or even one-half the average household income to one-tenth. That was a deliberate effort by government, corporations and agriculture working together. It takes time but it can be done.
