The film would replace the sheet of glass currently used with solar PV panels. “With HyperSolar as the top layer, manufacturers can use significantly fewer […]

Californian electricity to be 33 % renewables


One of the main hindrances of solar energy is that when there is no more sun, there is no more electricity as well. This problem is being solved with the molten salt technology which stores energy for seven hours. A Californian company is willing to build a 150 Megawatt plant […]

In these times of heat waves – it was 37°C here in France yesterday  – we all know that solar energy can heat places but it seems the sun could also cool them down thanks to air conditioning. Even if this is not entirely new as I read about such […]

Why solar air conditioning is a fantastic idea



I never write about renewable energy projects who will bring only a few megawatts to the grids.  I prefer to focus on huge plants that will bring at least several hundreds megawatts which are more interesting in a global scope. This is the case of two projects I heard about […]
