Solar Power: Promises and Subsidies


Harnessing sunlight for heating and other power purposes is not new. Solar collection devices were developed in the 17th century to protect plants brought from the tropics to northern countries, and both the first solar water heater and the first solar oven were developed the 18th century. Indeed, the solar power revolution has been on the verge of taking off for centuries.

In response to the Arab Oil Embargo, in part, the relatively new U.S. Department of Energy (along with other agencies) began a slew of programs to fund solar energy research, deployment and commercialization. Based strictly on performance, these programs have failed at the cost of billions of dollars of taxpayers’ money.

Is Solar Power the Answer?


By Don Aitkin

“I object to having to pay more for electricity that is produced inefficiently and erratically because some people are worried about the end of the world. In the 1980s, solar energy looked a possible way in the future of protecting our small and diminishing reserves of oil – because even then there were experts telling us that ‘Peak Oil’ had already arrived. It would never have occurred to me that we would be considering it as a source of baseline power. How would we store overnight the energy gained during the day? No one had the answer then, and no one has produced an efficient working model of the answer today. For isolated settlements and properties? Yes. For the grid? No.”

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.

Part Time Power


Solar power only works while the sun shines – it is part-time power.

Wind power only works when suitable winds blows – also part-time power.

Batteries only work when charged – part-time power again.

Hydro fails in droughts – more part-time power.

And using full-time power like gas to fill the inevitable supply gaps from part-time power forces backup gas to operate like part-time power.

Moreover, on sunny windy days, wind and solar generators spew out electricity at little extra cost. These erratic surges of part-time power drive short-term electricity prices so low that even low-cost full-time producers like coal cannot operate profitably at those times. They are throttled back and forced to operate as yet another part-time power plant.

24/7 electricity users such as hospitals, trains, factories, refineries, fuel and water pumps, cash registers, infrastructure and mines cannot operate on part-time electricity.

Moreover, every part-time power producer (using sun, wind, batteries, hydro, gas or coal) consumes money full-time for operations, standby, maintenance and replacement. Each also has to fund its own specialised generators, transmission lines, access roads and workforce. Electricity becomes both unreliable and expensive, and consumers suffer.

Using taxes, subsidies, dictates and mandates to replace a full-time power producer like coal with up to five part-time power producers only makes sense in the part-time minds that inhabit Greentopia.

Canberra cannot improve any of this with more laws and regulations – they must REPEAL all the legislation, regulations, subsidies and taxes that created the mess in the first place. State governments too should repeal their silly energy laws, and stop shutting and destroying power stations. More laws and regulations can only make things worse.

HYDRO ELECTRIC POWER, PUMP STORAGE AND BATTERY STORAGE


HYDRO ELECTRIC POWER, PUMP STORAGE AND BATTERY STORAGE.

Terence Cardwell

TUMUT 1 HYDRO ELECTRIC POWER STATION.

There has been so much talk and false information about Hydro Electric Power Stations, pump storage and System battery storage that I felt it was time to put the facts straight.

Some of the most incorrect and misleading information is from self appoint university experts who have made all sorts of ridiculous statements. As well as from some politicians who either live in fairy land or are deliberately lying. You decide.

Do I know what I’m taking about; I was with the Electricity Commission of N.S.W. for 26 years in a number of positions including the commissioning and in charge of the Coal Fired Thermal Generators at Tallawarra, Wallerawang and Munmorah Power Stations.

Why Wind Power does not Greatly Reduce Consumption of Hydrocarbon Energy


The problem with wind power is that electric utilities have to be prepared at any time for their power production to just stop on short notice. So they must keep fossil fuel plants on hot standby, meaning they are basically burning fuel but not producing any power. Storage technologies and the use of relatively fast-start plants like gas turbines mitigates this problem a bit but does not come close to eliminating it. This is why wind power simply as a source contributing to the grid makes very little sense.

Parasitic Power Producers


Promoting Parasitic Power Producers

Wind and solar are parasitic power producers, unable to survive in a modern electricity grid without the back-up of stand-alone electricity generators such as hydro, coal, gas or nuclear. And like all parasites, they weaken their hosts, causing increased operating and transmission costs and reduced profits for all participants in the grid.

Without subsidies, few large wind/solar plants would be built; and without mandated targets, few would get connected to the grid.

Green zealots posing as energy engineers should be free to play with their green energy toys at their own expense, on their own properties, but the rest of us should not be saddled with their costs and unreliability.

We should stop promoting parasitic power producers. As a first step, all green energy subsidies and targets should be abolished.

A Rational Look at Renewable Energy and the Implications of Intermittent Power


By Kimball Rasmussen | President and CEO, Deseret Power | November 2010
With Acknowledgement to: John Droz at the Alliance for Wise Energy: http://www.wiseenergy.org/

“Wind energy has a highly intermittent output that significantly mismatches demand and delivers energy largely when it is less needed. Wind cannot satisfy the demand requirements of a utility unless it is backed up with fossil fuel plants and/or energy storage projects. This results in duplication of resources and additional costs, with little, if any, carbon mitigation. Further, the steep increases and declines in power delivery of wind put the reliability of the grid in question. The tactic of switching off excess wind supply only diminishes the already weak pattern of intermittency and adds to the per kWh cost of wind. Typically, wind resources are located far away from where the power is needed and require significant additional costs of building new transmission. Intermittency, duplication and grid operations all significantly increase the already high cost of wind energy.

“Wind becomes even more questionable when proven solutions like natural gas can deliver even greater reductions in emissions at half the cost.

“While solar power is much more grid friendly than wind, it is generally the most expensive form of renewable energy. Solar energy quasi-matches system peak load periods, but the peak solar output significantly misses actual electric system load peaks. In addition, solar facilities still produce only about 18 to 25 percent of the time. Without electricity storage, solar energy will not be able to do more than serve as a supplement to other forms of energy. It is not currently a full-scale alternative to baseload energy.

“A Renewable Portfolio Standard, or mandate of 20 percent, can result in a utility-scale duplication of net investment in generating plant of 100 percent or more. The mandate can also cause the wide variation of rate impacts, depending on availability of renewable energy projects and other utility specific parameters.”
