One option for renewable energy producers that has been open to utility companies but rarely utilized, is the installation of both wind and solar power plants together at the same location, which results in a doubling in the amount of electricity produced. Prior to a study done by Reiner Lemoine Institut and Solarpraxis AG, it was (incorrectly) thought that the huge towers upon which the wind turbines are mounted would cast huge shadows over the photovoltaic solar panel array, thereby reducing their efficiency by a significant factor. It turns out that when solar and wind power generation are combined on the same site, such hybrid power plants complement each other better, than had been imagined. Approximately twice the power generation is available from any such hybrid power plant site, when compared to wind or solar only. The landmark study took into account the amount of sunlight loss (shading) which would occur in a carefully designed hybrid power plant. Energy losses were less than 2 percent of total output. This is a lower energy loss percentage, than compared to conventional power plant energy, such as coal — where up to 10 percent of the coal can be lost during transport from North America to China, or from Australia to China, and later storage, for example. A major benefit of such hybrid power plants is that due to the relative intermittency of both wind power and solar power is they tend to cancel out the others weaknesses. Grid expansion, is therefore not required for hybrid power plants. Wind power peaks at night, during cool days, and in the colder seasons of the year — while solar produces power during the daylight hours, the warmer parts of the day and most especially during the warmer seasons, when the Sun is high in the sky, directly over the solar panel array...

WARP Wind Amplified Rotor Platforms

This technology and others like it along with the use of recent PV thin film, solar paint material options and onsite storage innovations is where we should be headed. They could prove to be cost effective solutions that can make significant strides to reduce our reliance of fossil fuel power generation. Of course slight modifications may be required to provide reliable safety measures for installation and maintenance personnel as well as producing a safe environment for our wildlife population.

Flexible Hybrid Smart Structure Energy Systems

Finally, someone who's on to it!, (partially anyway) Very interesting research. 

Readers: if you happen to know of additional organizations or individuals with research in developing flexible hybrid smart structure systems that can generate energy from movement (also known as: vibration energy harvesting), as well as solar, Genergy (gravity energy) and / or hydro please post a link here. Especially if there are plans to utilize the height and overall structure of our current larger power grid towers that are located in high exposure areas like along the I-5 corridor. Not to mention, what about utilizing other newer sound infrastructure already in place like guard rails, bridges, etc... in this way? Excess energy can be stored underground in many cases with newly discovered technologies for later use during peak hours. I realize power companies own a portion if not all of the current power grid tower structures. Why not utilize them in this way as a viable addition to home alternative energy systems? It would give power companies an additional way to keep a piece of the pie for themselves without having to rely so heavily on fossil fuels. Lets get off the oil already!

Green energy invention showcases at House of Commons

Thursday 26 May 2011

The Rt Hon David Willetts MP, Minister of State for Universities and Science opened the event with other speakers including Mr David Sweeney, HEFCE Director for Research, Innovation and Skills, and Mr Liam Burns, President Elect, NUS.

Among those to visit the University's presentation were Lord Haskel, (pictured centre) and Bolton MPs Julie Hilling (left) and Yasmin Hussain (right). With them is PhD student Derman Vatansever and Director of Research, Professor Elias Siores.

Research That Matters looks at how modern universities contribute to national research, innovation and economic growth. The think tank says modern universities have a distinctive and valuable approach to research, working closely with business, public and third sector organisations. It is urging Government to support new universities' research, maintaining public investment.

Derman and Professor Siores, who are based in the University's Institute for Materials Research and Innovation (IMRI), were showcasing a new green-energy material.

The IMRI scientists have created a unique product – a flexible piezoelectric fibre that can be woven to create natural energy-harnessing fabrics. Energy is created as the material is moved. The researchers have added to it, patenting a method for creating a photovoltaic- piezoelectric fibre which would also harness the power of the sun, meaning the material could be a solar energy source as well.

Why the Success of the Smart Energy Grid Requires a Multipronged Approach

by Eric Dresselhuys

Eric Dresselhuys is the executive vice president and chief marketing officer for Silver Spring Networks and has more than 13 years of experience in developing smart grid solutions to address the industry’s most pressing challenges.
The prevailing discussion surrounding the smart grid is rightly focused on customer engagement. Sadly, that discussion has turned into an argument of gadgets versus behavioral modification tools — in-home displays and programmable thermostats versus community comparisons and social media. This argument creates a false dichotomy and runs the risk of keeping whole segments of people from engaging with their energy consumption habits. The reality is that energy efficiency is too important and broad for any one-size-fits-all solution. A portfolio of choices needs to be available, including some that haven’t even been thought of yet read the full article...

Vibration energy harvesting device for low frequency operation - IOP Science

 SUPPORTED AFFILIATE:

FEATURED ARTICLE
by Lei Gu and Carol Livermore

The "Impact-driven, frequency up-converting coupled vibration energy harvesting device for low frequency operation - IOP Science" paper presents experiments and models of an energy harvesting device in which a low frequency resonator impacts a high frequency energy harvesting resonator, resulting in energy harvesting predominantly at the system's coupled vibration frequency. Analysis shows that a reduced mechanical damping ratio during coupled vibration enables increased electrical power generation as compared with conventional technology. read more
