But you are incorrect, it is the best way. Domestic photovoltaics does not produce a large amount of power but it produces the most power during times of high demand and price. PV should be priced as "Peaking Plant" , people think that $0.60 /KWh is dear. The market can and does sell electricity up to $10.00 per KWh wholesale ($10,000 MWh). It is not a subsidy to renewable energy but an investment in infrastructure. Two years ago, last time I looked there were about 8 days when spot electricity prices were over $3,000 MWh ($3 KWh). Currently, the NSW electricity network needs over $10 Billion of upgrades. Installing a large amounts domestic PV would save at least $1 Billion in network charges. After 10 years of not owning coal mines, the NSW is going to open a new mine because they fear that if the coal-fired electricity plants had to pay the market price for coal (USD 104/Tonne) it would make electricity too expensive. A large-scale (1Gigawatt) coal plant cost between $5 -$10 Billion and at least 10-15 years to build. The associated distribution network is 2-3 times that price. Fuel (coal) cost per MWh circa $35 Carbon price (NZ price A$15 - Europe A$21) Capital cost ?????? Current National Wholesale Electricity Price (aka Pool price) $20.44 MWh (Yesterday) So, solar is much cheaper and installing on 'every' building would save a lot money but would upset many existing people including the government who is trying to sell the retailers, the unions, existing power companies and is not concerned with non-entities such as voters or customers.
