The 54 cents are for gross production. Which sounds like a lot, but this for all WA made systems so you cant get cheap deals. I figure with the federal 30% tax credit and the 54 cents/kWH produced, I will recover my investment by the time the incentives run out in 2020. So in 2020 I will have paid $0 for the whole 4 kW array (minus interest not earned over that period, but I still have the panels, which I expect will produce maybe until 2040).
Over the lifetime of the system this makes it reasonable long term investment. If energy prices go above 25 c/kWH (which I am certaint they will, eventually even here in WA), and panel prices come further down, residential Solar will make sense for everyone, even here in WA.
If we assume a residential PV system produces for 30 years, in WA its ~ 1000 kWH per kW installed, then you can figure that
at a cost e.g. $ 6000 per kW installed you get 30000 kWH or 20 c/kWH for the lifetime of the system. In any sunnier location, this would be even less. I bet in places like CA, AZ or FL it is even now almost on par with utility generated power.

Andy, no one is building soviet era Chernobil reactors anymore, the new stuff is far far safer... and less than 40 people died at Chernobil, 4000 more may get cancer from all the radiation.. (those numbers are off the top of my head so dont hold me to them) and that was a horrible accident with a naked core actually burning in air.
Herm wrote:I have no idea how many people died building all those solar panels but I bet a lot since most of the power in China used to build them comes from coal. I'm not saying that solar panel factories should only be powered by solar but dont assume their innocence. The expense of solar panels also means that people starve and die of disease due to lack of funds.. how much money did the Germans divert from famine relief in Africa to build their infrastructure?
Cement production is one of the most energy intensive of all industrial manufacturing processes. Including direct fuel use for mining and transporting raw materials, cement production takes about six million Btus for every ton of cement (Table 2). ... The industry’s heavy reliance on coal leads to especially high emission levels of CO 2, nitrous oxide, and sulphur, among other pollutants. A sizeable portion of the electricity used is also generated from coal.
Maybe you're right about fusion, maybe not - but we don't need it now - we have all the tech we need today with ZERO R&D.Herm wrote:We need nukes, solar and wind when we stop using fossil fuels to generate electricity .. I dont think fusion will ever amount to much.
Others seem to disagree with you about wind's usefulness without storage (though it will be an improvement when it happens). But since we already have a continental wide grid, and we have grid-scale storage in use today, I'm thinking we're golden here!Herm wrote: Wind is useless without backup, storage or continental wide grids.
The hoped-for remedy is a battery, a Texas-size battery, which could eventually end up playing an important role in wider use of green power generation such as solar and wind. The U.S. $25 million system, which is now charging and is set to be dedicated April 8, will be the largest use of this energy storage technology in the United States.
American Electric Power (AEP) first tested the NaS system for stationary power at its Dolan Technology Center near Columbus, Ohio, and deployed it in a demonstration project in Gahanna, Ohio, in 2002. Since then, AEP has installed four NaS battery systems in West Virginia, Indiana, and Ohio.
A solution to improve wind power reliability is interconnected wind power. In other words, by linking multiple wind farms together it is possible to improve substantially the overall performance of the interconnected system (i.e., array) when compared with that of any individual wind farm. The idea is that, while wind speed could be calm at a given location, it will be noncalm somewhere else in the aggregate array
If you think the water on lawns is not to be a concerned affair, that may usually cost 20% of the total utility power of the region. That would be a fair figure to maintain lawns, 20% of your power is used in pumping water to maintain lawns. Lawns use 44% of the total water used in your home. If you think that is a slight thing, 13% of all energy is produced by atomic power - you make the next step yourself. Lawns cost you atomic power.

The contribution of nuclear power to climate protection is relativized when taking into account the declining ore grades: Nuclear power can be referred to as “low-carbon” when the ore grade are high (0,1 bis 2 %). However, ore grades around 0,01 % make the CO2 emissions increase up to 210 g CO2/kWhel. Those emission values are still lower than those of coal or oil (600–1200 g/kWhel), but significantly higher than for wind (2,8–7,4 g/kWhel), hydropower (17–22 g/kWhel) and photovoltaics (19–59 g/kWhel). Moreover it would be costly and slow to use nuclear power as means for reducing green house gas emission; it would take decades, until a net reduction of GHG would have occurred (Pasztor 1991; Findlay 2010). The CO2 avoiding costs of nuclear power are than for any other possible technology except traditional coal fired power plants. Wind power stations and cogeneration of heat and power are 1,5 times more cost-effective in reducing CO2 than nuclear power, energy efficiency measures are 10 times more cost-effective.
Further problems of nuclear power generation remain unsolved:
- Accident liability is unsolved. Worldwide, nuclear power plants are legally exempt from the liability for catastrophic accidents.
- Health risks from radiation of nuclear power plants cannot be excluded. In Germany, a study conducted by the German Deutschen Kinderkrebsregister (German Paediatric Cancer Registry) proves increased leucemia rates for children in the surroundings of nuclear power plants. (Kaatsch et al. 2007).
- While the Operationable uranium resources will not last longer than this century, the highly radioactive waste has to be stored safely for thousands of years. No storage concept was developed yet for the 245.000 tons of spent fuel elements nuclear power generated already worldwide.
- Nuclear power used for electricity generation is the biggest driver of proliferation of fissile material. Without nuclear power generation, proliferation attempts could be identified undisputedly, because each effort to acquire fissile material would clearly serve military purposes.
- Nuclear power leads to higher electricity prices, because direct and indirect subsidies cover up the enormous costs of nuclear energy. Worldwide no reactor was built, where private investors would have carried the financial risk. If nuclear power in a liberalised market would actually lead to low electricity prices, it should not be a problem to find private investment to build new reactors.
- Nuclear power is a high-risk technology due to the risks connected with it. However, in connection with the need of protecting the climate, this energy form is also called “lowcarbon”.

Declaration of the Occupation of New York City
This document was accepted by the NYC General Assembly on September 29, 2011
As we gather together in solidarity to express a feeling of mass injustice, we must not lose sight of what brought us together. We write so that all people who feel wronged by the corporate forces of the world can know that we are your allies.
As one people, united, we acknowledge the reality: that the future of the human race requires the cooperation of its members; that our system must protect our rights, and upon corruption of that system, it is up to the individuals to protect their own rights, and those of their neighbors; that a democratic government derives its just power from the people, but corporations do not seek consent to extract wealth from the people and the Earth; and that no true democracy is attainable when the process is determined by economic power. We come to you at a time when corporations, which place profit over people, self-interest over justice, and oppression over equality, run our governments. We have peaceably assembled here, as is our right, to let these facts be known.
They have taken our houses through an illegal foreclosure process, despite not having the original mortgage.
They have taken bailouts from taxpayers with impunity, and continue to give Executives exorbitant bonuses.
They have perpetuated inequality and discrimination in the workplace based on age, the color of one’s skin, sex, gender identity and sexual orientation.
They have poisoned the food supply through negligence, and undermined the farming system through monopolization.
They have profited off of the torture, confinement, and cruel treatment of countless animals, and actively hide these practices.
They have continuously sought to strip employees of the right to negotiate for better pay and safer working conditions.
They have held students hostage with tens of thousands of dollars of debt on education, which is itself a human right.
They have consistently outsourced labor and used that outsourcing as leverage to cut workers’ healthcare and pay.
They have influenced the courts to achieve the same rights as people, with none of the culpability or responsibility.
They have spent millions of dollars on legal teams that look for ways to get them out of contracts in regards to health insurance.
They have sold our privacy as a commodity.
They have used the military and police force to prevent freedom of the press.
They have deliberately declined to recall faulty products endangering lives in pursuit of profit.
They determine economic policy, despite the catastrophic failures their policies have produced and continue to produce.
They have donated large sums of money to politicians, who are responsible for regulating them.
They continue to block alternate forms of energy to keep us dependent on oil.
They continue to block generic forms of medicine that could save people’s lives or provide relief in order to protect investments that have already turned a substantial profit.
They have purposely covered up oil spills, accidents, faulty bookkeeping, and inactive ingredients in pursuit of profit.
They purposefully keep people misinformed and fearful through their control of the media.
They have accepted private contracts to murder prisoners even when presented with serious doubts about their guilt.
They have perpetuated colonialism at home and abroad.
They have participated in the torture and murder of innocent civilians overseas.
They continue to create weapons of mass destruction in order to receive government contracts.*
To the people of the world,
We, the New York City General Assembly occupying Wall Street in Liberty Square, urge you to assert your power.
Exercise your right to peaceably assemble; occupy public space; create a process to address the problems we face, and generate solutions accessible to everyone.
To all communities that take action and form groups in the spirit of direct democracy, we offer support, documentation, and all of the resources at our disposal.
Join us and make your voices heard!
