Renewable power has constantly had a cost issue, because it is more expensive than fossil fuels. Researchers have now produced a solar cell that is efficient enough to be financially competitive with fossil fuels. Article resource: New solar cells could make solar power mass-market cheap
Cell created
By capturing heat from photovoltaic cells, plastic semiconductors produced by the National Renewable energy Laboratory are much more effective than previous solar cells. These solar panels create more energy with fewer cells, reducing the cost drastically. The process allows a rise in theoretical efficiency of a solar cell from 31 percent to 66 percent.

My original hypotheses on this blog, were derived from an inspection of various graphs about the evolution of the climate over the last 65 Myrs, and I based my conclusions on this and knowledge I had about geology and human evolution.
I came to the conclusion that AGW was both an integral component of the earth system and a desirable outcome. I have appended some references below, with links. Link 3 is a discussion of human evolution in Africa, and the contention that human evolution was driven by climate (ice ages). Link 4 is a new in-depth paper with new correlations to changes in climate specifically transitions between wet and dry climates.
These are not new contentions, although the second paper has a detailed set of evidence based correlations. I do not intend to discuss either of these papers in any more depth but urge the reader to check them.
The information in the links 1 & 2 contain new information to me which I believe supports my previous ideas.
With the continuous increasing energy demand and the depleting supply of fossil fuel sources, Renewables will become a major energy source in the future. In order to integrate Renewables, our society is facing several major challenges, e.g. coping with the intermittency, transporting electricity cross large distances and demand side management.
There are several scenarios that offer possible solutions
Renewables cost reduction and reaching grid parity
Energy storage technologies available for both generation side and grid side
Large scale high voltage transmission
Using fossil fuel (mainly gas) to bridge the intermittency
To utilize these solutions, energy storage solutions will play an important role in all possible scenarios.
Overview of Energy Storage Technologies by category
Depending on applications, the energy storage solutions can be segmented based on the discharging time, typically

Monday NASA announced the detection of the first Earth-like planet in the habitable "Goldilocks zone." Researchers say is could be able to support life as we know it. The world, called Kepler 22-b, is 600 light-years from us. It was found using the Kepler orbiting space telescope. Researching this world will be the next large NASA project if it is viable for humans. http://www.newsytype.com/
All about the zone
The so-called "Goldilocks zone," refers to a planet's distance from the star it orbits. If it is "not too hot and not too cold," it might be capable of sustaining liquid water, which is necessary for life as we know it. It is a comfortable 72 degrees on Kepler 22-b.
The Astrophysical Journal will be where this is published.
It is easy to transpose the terms positive and negative feedbacks when discussing a dynamic system, I have managed to fall into this trap myself on several occasions while writing this blog, so for the sake of clarity I will define the terms and then apply these terms to the climate system.
Negative Feedback: is processes within a system that oppose change by applying a opposition to the force making the change thereby reducing the amplitude/attenuating the output of the system. By extrapolation any dynamic system such as the earths climate, which has existed for billions of years, is dominated by negative feedback, otherwise our climate would have shown extreme behaviour.
Positive Feedback: is that process which amplifies the change and in the most extreme instance causes runaway change.
Is AGW Religion, Politics or Science
I have developed a theoretical model of climate change against which I will attempt to quantify the reactions of others.
The greenhouse effect is sound science and has a measured effect on temperature approximately equal to 0.8 deg C for a doubling of CO2 concentration. AGW proponents then try to equate additional warming of up to 5 deg C to CO2, attributed to accumulative effects, this is both anti-scientific and analogous to an article of faith. Politicans and business then use these hysterical projections to obtain either huge profit, Global domination or both, all sane men should be suspicious of all but the science.
My model suggests that large reactions to parametric changes are only driven by ice induced negative incursions, where positive feedbacks will amplify the negative Insolation lobes or CO2 reductions such that a halving of CO2 from current levels is the only forcing which will be amplified by the system.
A CO2NVENIENT LIE (apologies to Al Gore)

CO2 has been the environmental bogeyman of the last 25 years. Green activists have been bemoaning the loss of global ice coverage, polar bear extinction, and rising sea levels etc.
THE LIE is that CO2 is an unnatural consequence of human civilisation, because it is easy to measure its effects, and blame all civilisations ills on CO2 as a pollutant.
THE TRUTH is anthropogenic CO2 has ballanced falling insolation and achieved the following positive effects.
1. Maintaining average global temperatures above 0degC Vostok
2.
