Interesting article from New Science describing how a "coronal mass ejection" from the Sun could melt down the electrical power gird. ".... Over the last few decades, western civilisations have busily sown the seeds of their own destruction. Our modern way of life, with its reliance on technology, has unwittingly exposed us to an extraordinary danger: plasma balls spewed from the surface of the sun could wipe out our power grids, with catastrophic consequences..." The article does offer a solution: upgrade the ACE solar satellite, to detect an electro magnetic surge and provide power grid operators with about 15 minutes to shut down their systems. The article does not discuss another possible option: stop building centralized power sources that demand increasingly massive power grids. Instead, concentrate on meeting energy needs using localized sources of power; like the highly portable Hyperion Power Module.

Two strong potential candidates for the Next Big Thing in cleantech venture capital are nuclear and carbon capture and storage. I've spoken with numerous VCs recently who are looking for innovative ways to play in nuclear power. Bets have already been made by VCs in small-scale nukes, hot fusion, and technologies related to big-scale nukes. The hope is to find a low-cost solution that is practically zero carbon emissions and also provides reliable "base load" power. So in other words, the hope is for a lower-carbon replacement for coal power. The challenges are also significant, however, not least of which being time to market for any new innovations, as this interesting article illustrates. With the recent news that the DOE will be putting $2.4B into carbon capture and storage, and its inclusion in emerging climate legislation, it's also clear that CCS will be leaned upon as a hoped-for way of making our existing coal-fired generation infrastructure less impactful on the atmosphere, while still preserving its value as low-cost baseload power. So in other words, the hope is for a lower-carbon "fix" for coal power.

Alpha Energy recently introduced its enhanced integrated solar power uninterruptible power supply. "As a UPS, the Solaris is the ideal solution for people or organizations wanting to minimize their carbon footprint, but have a critical power need. The Solaris lets you take advantage of free and clean solar power, and at the same time you can rest assured that in the event of a power outage, a supply of that solar energy is available for future use." The Solaris is a single-box solution providing up to 3.5kW of continuous power.

As part of the "Metropolitan Solutions" exhibition at the Hanover Fair, Siemens Energy will present four selected projects providing energy-efficient, ecofriendly power supply solutions for megacities.

In the spectrum of the simplest solutions (turning lights off) and the most complex (fusion), you've categorised this solution at the right end of the spectrum

The micro inverters are used in the solar industry where you can easily install the components much better than the central inverters

There are many energy conservation tips taken to have the green power in your surrounding region. Also the charges for the fossil fuels are increasing a lot and creates harm for the environment too.

Switch to the future power generation of SOLAR energy for office, warehouse, etc..

Sure, regenerative braking - the process that converts the energy typically wasted as heat when slowing down and storing it as electrical power in batteries - is a terrific energy saving solution. Many hybrid cars, such as the Prius, use regenerative braking and it's starting to appear aboard hybrid diesel/electric trains as well. But more efficient still is to maintain your momentum and dispense with a train's need to make stops

all the matter from those next solutions... no more than oil loss again ! ... what's next real good solutions ?

but what's to find ? new nanomaterials ?

"Generating 20 percent of America's electricity with wind, which is crucial to our future safety, growth and prosperity, would require building up to 22,000 miles of new high-voltage transmission lines."

Shell highlights the view that renewable energy solutions are some way from offering a large-scale solution to our planets growing energy needs. The matters of finance and technology development breakthroughs appear to be the largest barriers to market, according to Shell. This view supports the notion that the world will be powered by a mix of fossil fuel, nuclear and renewable energy for the forseeable future.
