Of Cabbages, and Kings, and Tariff Feed-ins


“The time has come,” the Walrus said,
“To talk of many things:
Of shoes–and ships–and sealing-wax–
Of cabbages–and kings–
And why the sea is boiling hot–
And whether pigs have wings.”

The Walrus and The Carpenter, Lewis Carroll, from Through the Looking-Glass and What Alice Found There, 1872

Once upon a time there was a land where cabbages were very popular. People used them for all sorts of things. There were central farms where they were grown, and distributed to supermarkets from where people bought them. The subjects in this land could buy the cabbages for about 17 cents each.

One day the King decided that it was a bad thing for the cabbages to be produced by these large farms. He said it hurt the environment to have them transported all the way to the supermarkets. He also said too much water was used on those farms.

Solar Power Realities – Addendum


By Peter Lang

This paper compares the capital cost of three electricity generation technologies based on a simple analysis. The comparison is on the basis that the technologies can supply the National Electricity Market (NEM) demand without fossil fuel back up…

The three technologies compared are:

1. Nuclear power;
2. Solar photo-voltaic with energy storage; and
3. Solar thermal with energy storage.

Solar Power – a Subsidised Appendage


By Viv Forbes, Chairman, The Carbon Sense Coalition.

Australian electricity consumers can look forward to soaring charges for electricity and blackouts if state and federal politicians continue to undermine the power grid by mandating and subsidising solar power generation.

Solar power can never produce continuous, predictable low cost power. It must always be supported by expensive power storage systems or by reliable power sources such as coal, gas, hydro or nuclear.

No matter how many millions of taxpayer money is poured into “research”, it can never solve the two fatal flaws of solar power.

Solar Power Realities


Supply-Demand Characteristics, Storage and Capital Costs
By Peter Lang

This paper provides a simple analysis of the capital cost of solar power and energy storage sufficient to meet the demand of Australia’s National Electricity Market. It also considers some of the environmental effects. It puts the figures in perspective…

Conclusions: solar power is uneconomic. Government mandates and subsidies hide the true cost of renewable energy but these additional costs must be carried by others.

Solar Energy Costs & Economics


As an interesting fact on solar, I had a quote done for my house in Florida for a 2.5kw array (not enough to power the whole house, about 1/3 of the average requirement). The cost benefit worked out as follows:

Cost to purchase and install: $25,000 – this yielded a return of less than 1% on investment (about 0.7%)
Federal tax credit of $7,500
State rebate of about $9,600
Yield after subsidies (if qualified) – a total net cost of $7,900 with a return on my investment of just over 6%.

In other words the state and federal governments (taxpayers) would pay $17,100 in subsidies to support an overall yield on the total investment (theirs and mine) of 0.7%.

Every scrap of the product installed is of foreign manufacture sending the bulk of the taxpayer money overseas.

As a business person, if my company invested in 0.7% return projects, I would be out of business. I wonder if that applies to the Feds and States?

Is solar energy a viable solution to reducing oil dependence?


by Allan Taylor
From

No, solar energy is not the solution to reducing US oil dependency.

Considerable progress has been made in the development and use of solar energy world wide over the last decade. This is a good thing and no doubt will continue. But where does solar energy fit into the overall energy crisis problem?
