Patrick Harvie, Scottish Green Party Co-Convenor | Patrick Harvie. Transparent solar collectors may replace conventional windows. Researchers working at Michigan State University (MSU) have created a completely transparent solar collector which is so clear that it could replace conventional glass in windows. The new devices – dubbed transparent luminescent solar concentrators – have the potential to not only turn windows into solar electric generators, but the screens of smartphones, vehicle glazing, and almost anything else that has a see-through surface. Experiments with transparent solar collectors have been conducted for quite some time now, but they have resulted in variable success and many poor results – particularly around the inefficient production of energy. More to the point, most of the produced materials weren't completely transparent, rather being brightly-colored or too darkly tinted.
"No one wants to sit behind colored glass," said Richard Lunt, assistant professor of chemical engineering and materials science at MSU. The research recently featured in the journal Advanced Optical Materials. Share. End fuel poverty.
© 2011 McCamley Ltd. How to get lower energy bills: thePeoplesPower. The concept is simple. Energy bills are really expensive for everyone, but as individual households we have no power to negotiate. thePeoplesPower believes that by negotiating together, we have the power to get a cheaper, fairer deal. (October 2013) At present we think people are better off switching NOW - and not waiting for another collective switch. (Find out more) We are offering £10 per fuel cashback whether you switch by internet or phone (Ofgem had said that all cashback were supposed to end by October 23nd – however, it seems that Ofgem have allowed cashback incentives to remain till December 31st). If this situation changes we will have to stop the cashback offer with no notice. Switch Now! Switch Now! ThePeoplesPower is a UK website where people can sign up their household for the cheapest electricity and gas.
ThePeoplesPower and our switching partner energyhelpline ask energy companies (the big ones as well as most of the smaller ones) to give us their cheapest energy deal. Ofgem guidance on collective purchasing & switching: thePeoplesPower. 1st May 2012. Yesterday afternoon (30/4/2012) Ofgem wrote an open letter offering guidance on the legality of collective switching schemes. In general Ofgem “generally welcome” the development of collective purchasing schemes. In particular, schemes which place an emphasis on involving vulnerable or currently non engaged customers were singled out as being particularly welcome. This is good for thePeoplesPower as we place a special emphasis on trying to help people switch their electricity or their main gas when they are at risk of or suffering from fuel poverty (see our work with Housing Associations) Ofgem’s General conclusions All quotes on this page can be found in the Ofem Open letter on their website (PDF file) and (RMR – is Ofgem’s Retail Market Review – a consultation that has just been completed by Ofgem with the energy industry on how domestic supply should be reformed.)

Energy Purchase & Sales — Community Renewable Energy.
A community renewable developer can recoup some, if not all, of its costs by entering into agreements with utilities to purchase the output of the project. In addition to energy, a utility may place value on, and hence be willing to pay for, capacity, identified distribution or transmission benefits, and environmental benefits. Some typical arrangements are described in more detail below. For more on the value of renewables to utilities, click here. Power Purchase Agreements Power Purchase Agreements (PPAs) are legal contracts between buyers and sellers of energy and capacity, and specify important details of the transaction, including the term of the contract and price paid for energy. When negotiating a PPA, environmental attributes, often called Green Tags or Renewable Energy Credits are usually sold with the power, but this must be specified in the PPA or it will be assumed that they are owned by the project owner.
PURPA and Avoided Costs Net Metering. Summary: Neighbourhood or community group purchase and distribution of energy saving equipment | Community Pathways. Installation or use of energy saving equipment reduces household's energy bills as well as reducing their carbon emissions. Providing community members directly with the physical means to improve the energy efficiency of their homes overcomes barriers of inertia and feelings of hassle, which enables them to take action. At the same time, working together on a shared agenda strengthens social norms, which can reinforce the low carbon activities being undertaken, and increase the potential for future actions. Purchasing in bulk may also be a way to get discounts, or at least an efficient way to seek 'best buys' on behalf of the community. It may also be more effective as a group to seek funding than as separate individuals, for example from energy suppliers or other commercial bodies with new products to promote or environmental or social objectives and targets to meet.
Piezoelectricity. A piezoelectric system (without contact tabs) Piezoelectricity is found in useful applications such as the production and detection of sound, generation of high voltages, electronic frequency generation, microbalances, and ultrafine focusing of optical assemblies. It is also the basis of a number of scientific instrumental techniques with atomic resolution, the scanning probe microscopies such as STM, AFM, MTA, SNOM, etc., and everyday uses such as acting as the ignition source for cigarette lighters and push-start propane barbecues. History[edit] Discovery and early research[edit] The pyroelectric effect, by which a material generates an electric potential in response to a temperature change, was studied by Carl Linnaeus and Franz Aepinus in the mid-18th century.
A piezoelectric disk generates a voltage when deformed (change in shape is greatly exaggerated) The Curies, however, did not predict the converse piezoelectric effect. World War I and post-war[edit] World War II and post-war[edit]
