While the risk of power cuts this winter is gradually fading, the importance of diversifying the electricity supply in France and Europe remains a key subject at the start of the year. This may be an opportunity to bring your solar installation projects out of the closet!! Especially since the advantages of this type of electricity: renewable, inexhaustible and storable, […]

Photovoltaic solar: comparisons around Alma Solar's "I'm solar 400W" panel
The increase in energy bills is the unavoidable subject of the moment, especially since the increase affects many daily services. In this context, we find it interesting to recall the advantages of photovoltaic solar energy. Especially since the prices of solar panels, such as the I'm solar 400W panel, seem to remain rather stable despite the […]
Énergie Thermique des Mers (ETM) or Ocean Thermal Energy Conversion (OTEC): renewable energy with great energy potential
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 […]
Photovoltaic wins the agricultural sector
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 […]
How to choose a solar battery for your photovoltaic installation in 2022?
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 […]
All about photovoltaic solar panels in 2022 and their specificities
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 […]
Install photovoltaic panels in 2022? An interesting solution towards energy independence
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 […]
Prosumer tariff: technical and legal argument justifying its elimination
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, […]
Prosumer tax: the CWAPE and the Walloon Region retroactively tax small solar producers
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 […]
Calculation of the Prosumer Tax: the tariff simulator calculator
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 […]

Renewable energies: advantages and disadvantages
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 […]
UN: get the right to energy autonomy on the UDHR
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 […]

Energy transition: Portugal powered for 4 days entirely with renewable electricity!
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 […]
