Renewable Energy Information
ETM (also known by its English acronym OTEC for Ocean Thermal Energy Conversion) is a relatively unknown renewable energy but with considerable energy potential! The ETM had already been approached a few years ago on the forum energies. Brought back to the fore by the legislative elections in Polynesia, in particular […]
Photovoltaics, which consists of transforming energy produced by the sun into electricity, has experienced significant development in recent years. It has even spread to the agricultural sector and is adopted in most agricultural regions of the world. This merger between photovoltaics and the agricultural sector is known by different names […]
After having approached the installation of photovoltaic panels, it seems logical to us to cover the subject of batteries, essential for the realization of an autonomous solar installation or to increase its solar self-consumption. Indeed, if you have opted for an off-grid installation therefore not connected to the electricity grid, the electricity produced by your solar panels will have to […]
Since the demonstration of the photovoltaic effect by Antoine Becquerel in 1839 and the presentation of the first photovoltaic cell by Bell Laboratories in 1954, photovoltaic technology has come a long way before reaching this astonishing level such as it is today. currently knows. Nowadays, the equipment born from this […]
The transition to solar energy production in France should accelerate for companies and public buildings thanks to the solar plan in 2022. This energy production involves the installation of photovoltaic panels allowing the production of solar electric energy carbon-free. But what about individuals? With the collapse of solar photovoltaic prices, divided by […]
In developing the prosumer tariff (falsely called tariff but it is a tax), the CWAPE limited itself to taking over in full, like a copy and paste, the “network costs” part of the price per kWh invoiced to consumers, by ultimately and erratically putting prosumers on the same footing as ordinary consumers, which, on top of that, […]
The Walloon Region (French-speaking part of Belgium) has implemented a retroactive prosumer tax for all solar photovoltaic installations in Wallonia. This tax concerns more than 150 installations and at the rate of a fixed floor price of € 000 to € 200 per year for a 300 kWp installation, it weighs more than […]
The prosumer tax, falsely and fraudulently called the prosumer tariff, is a fixed part tax (from 200 to 300 € per year depending on your GRD on a basis of 3 kWp) and variable on all photovoltaic installations in Wallonia. And it is because there is an incompressible fixed part that it is not a […]
LESBAT adsorption solar refrigeration: Catherine Hildbrand, Olivier Cherbuin, Julien Mayor. Project manager: Philippe Dind The aim of this article is to present the principle of adsorption solar refrigeration, which quite simply makes it possible to cool with solar radiation. What is solar refrigeration? The laboratory […]
What is the solar energy potential in your region? Two maps of France showing average sunshine showing the energy potential of solar energy. Keywords: solar energy, photovoltaic, thermal, water heater, potential, France, region, kwh / year, m2, m². You will find a more detailed map here: DNI solar map of France and some solar panels and products […]
Nowadays, no one is unaware of the existence of renewable energies. Indeed; they have developed significantly in recent years and offer impressive advantages, particularly economic ones since, for example, in 2021, solar electricity is now cheaper to produce than nuclear electricity! Thus, so-called renewable energies are increasingly favored […]
This text proposes to add the notion of access to energy autonomy to article 25 of the Declaration of Human Rights. This is so that access to energy no longer depends exclusively (or almost) on multinationals, some of which have become richer than many countries! This text should be addressed to political decision-makers, institutional and not […]
Sizing of an Archimedes screw for hydroelectricity - INSA Strasbourg. Optimization of an Archimedean screw for energy production in micro-hydroelectric power stations. by Guilhem DELLINGER, Abdelali TERFOUS, Abdellah GHENAIM, Pierre-André Garambois KEYWORDS: Fluid mechanics, Renewable energy, Micro hydroelectric power station, Archimedean screw, Experimentation Summary The use of Archimedes screw in micro hydroelectric power stations is a way […]
While France continues to bet (almost) everything on nuclear electricity… countries are currently breaking records for renewable electricity production! This month it's Portugal's turn to achieve a real tour de force of renewable energy! A few days after Germany produced so much renewable electricity that producers […]
The Fourth Revolution: Towards Energy Autonomy Documentary by Carl-A. Fechner (Germany, 2010, 1h22mn) Going beyond the pessimistic warnings on climate change, this documentary shows that solutions are possible to switch to renewable energies in the next thirty years. In various regions of the planet, the film goes to meet […]

Making a geodesic solar parabola This document presents the manufacture of a parabola for satellite traffic but also enables the manufacture of a solar parabola because the dimensioning is the same. Only the surface coating changes in the case of a solar dish. Find out more: - Manufacture of a solar oven - Calculations and design of a […]
Presentation of our solar-recharged electric-assist bicycle This assembly is based on the foldable electric-assist bicycle that we bought in the spring of 2009. Here is a subject which presents this foldable electric bicycle. We have equipped it with a small “trailer” to increase the load carrying capacity (almost zero without except bag […]
Online publication of a legal database on renewable electric energies in the EU-25 Since 13 August 2008, any interested person can access free of charge an online database containing, for the Member States of the Union European Union of 27, important legal information on the national measures currently in force in […]
Memo guide to a photovoltaic solar installation for the industrialist and the installer 4-page memo document edited by Ademe for installers, which allows them to "know everything" about a photovoltaic solar installation made in France. To read absolutely if you have a solar PV project in progress in order to verify the information provided by your […]
