Solve for X: Danielle Fong on economical energy storage. Solve for X: Bill Gross on solar cheaper than natural gas. Jean-Marc Jancovici et le solaire. Billet publié initialement le 18 mai 2013. EDIT: TF1 Bouygues, EPR, UK: "c’est EDF qui opérera des centrales construites en grande partie par Bouygues avec des équipements Areva" ---- Jean-Marc Jancovici, président de "The Shift Project" financé par le groupe Bouygues-TF1 et Vinci Autoroutes, vient de signer une tribune dans Les Echos où il affirme que le solaire photovoltaique "demande de 10 à 30 fois plus d'investissement par kWh produit que le nucléaire (gestion de l'intermittence incluse)".
Un EPR de 1,6 GW, c'est un investissement d'au mois 8,5 milliards d'euros, c'est à dire 5,3 euros investis par watt installé, et un facteur de capacité de 90%. Concernant le solaire PV, c'est 1,5 euros par Watt installé, et un facteur de capacité moyen de 15%. En conclusion le solaire coûtait 40% plus cher que le nucléaire en 2011. Solar Power Much Cheaper to Produce Than Most Analysts Realize, Study Finds.
By Joe Romm on December 11, 2011 at 10:22 am "Solar Power Much Cheaper to Produce Than Most Analysts Realize, Study Finds" The public is being kept in the dark about the viability of solar photovoltaic energy, according to a study conducted at Queen’s University. “Many analysts project a higher cost for solar photovoltaic energy because they don’t consider recent technological advancements and price reductions,” says [co-author] Joshua Pearce, Adjunct Professor, Department of Mechanical and Materials Engineering. “Older models for determining solar photovoltaic energy costs are too conservative.”Dr. Pearce believes solar photovoltaic systems are near the “tipping point” where they can produce energy for about the same price other traditional sources of energy.
That’s the news release for a new journal article, “A review of solar photovoltaic levelized cost of electricity” (subs. req’d). Here’s more for the news release (plus some more must-have CP charts): (Chart from Emanuel Sachs of MIT. Solaire, quelles réaltiés pour 2020? 2011.pdf.
TEDxSacramento - Scott Brusaw - The Promise of Solar Roadways. Solar Roadways - A Real Solution. Twin Creeks Technologies - Less is More. Solar panel made with ion cannon is cheap enough to challenge fossil fuels. Twin Creeks, a solar power startup that emerged from hiding today, has developed a way of creating photovoltaic cells that are half the price of today’s cheapest cells, and thus within reach of challenging the fossil fuel hegemony. The best bit: Twin Creeks’ photovoltaic cells are created using a hydrogen ion particle accelerator. As it stands, almost every solar panel is made by slicing a 200-micrometer-thick (0.2mm) wafer from a block of crystalline silicon. You then add some electrodes, cover it in protective glass, and leave it in a sunny area to generate electricity through the photovoltaic effect (when photons hit the silicon, it excites the electrons and generates a charge).
This is where Twin Creeks’ ion cannon, dubbed Hyperion, comes into play. According to Technology Review, ion beams have been considered before, but particle accelerators were simply too expensive to be commercially viable. Read more at Twin Creeks.
Bient t des centrales solaires le long des voies de chemin de fer. Eolfi, filiale de Veolia Environnement, et Réseau ferré de France (RFF) ont annoncé ce lundi la création d’une société commune, dénommée «Airefsol Energies». Elle sera chargée de concevoir et développer des centrales de production d’électricité verte sur les espaces fonciers de RFF dont il ne se sert pas pour ses activités ferroviaires. Avec un patrimoine de 103.000 hectares, RFF est le deuxième propriétaire national. Airefsol Energies a recensé une vingtaine de sites, répartis sur l’ensemble du territoire national. «Les terrains ont été sélectionnés selon leur pertinence géologique et environnementale, le souci de préservation des milieux naturels, l’intérêt économique», indique la compagnie dans un communiqué. Une première tranche, destinée à la production d’électricité photovoltaïque, visera un objectif de 100 MW.
Eolfi est un producteur d’électricité verte, qui développe des parcs éoliens et solaires, en France, en Espagne, en Grèce, en Pologne ou aux Etats-Unis. 10 Myths Surrounding Solar Energy. “Solar panels are unsightly, have low efficiency, cost tons of subsidy money and have a high carbon footprint. " Edwin Koot addresses the 10 major myths surrounding solar energy. 1. Generating solar energy is only possible in countries with an abundance of sunshine The fact is, the sun's energy is the most evenly-spread source of energy in the world. In any part of the world where there is light, solar panels will work. Of course, when you’re developing systems in the Sahara region, your return on investment (ROI) will be higher - but many other factors come into play, such as the presence of a grid, the local consumer price for electricity, your energy usage pattern, the political stability in your country, your need for independence from external sources of energy, and much more. 2.
Solar energy is an attractive product in any place in which people need electricity - which nowadays is anywhere in the civilised world, globally. 3. “People will never buy laptops.” 4. 5. 6. 7. 8. 9. 10. Why Big Solar is a Colossally Bad Idea (10 Reasons Decentralized Solar is Much Better) – CleanTechnica: Cleantech innovation news and views. Clean Power Published on April 27th, 2011 | by Aaron Fown Of late there has been much talk about moving towards a solar energy future. This is a positive development (albeit one that is almost too late) and has been driven, no doubt, by recent studies that have shown that solar and wind power are now amongst the cheapest forms of power generation, several critical breakthroughs in related fields, and big moves by some major players. However, it seems that a lot of money is being thrown at a particular type of solar power plant; massive centralized solar plants.
We have an opportunity to build a new power system to replace our failing grid with something more resilient, more efficient and more egalitarian, and if we don’t take this opportunity we will be stuck with mild changes to the old system. In fairness, centralized solar does have a few benefits, so let’s start with them before I explain why a decentralized system would be a much better choice. 1. 2. 3. 1. 2. 3. 4. 5. 6. 7. 8. 9.
