It's important to consider the management of battery-based wind energy systems. Reference has been made to solar energy systems, but we all know that solar panels do not work at night. In Quebec City, there were five meters of snow on the ground at one point. Solar panels had to be heated so that snow would not accumulate on them. And we haven't even talked about the energy required to produce those same solar panels. You may have a solar panel, but the fact is that twice as much energy is required to make a photovoltaic cell with silicone than what a solar panel produces, in terms of energy, in ten years. Some colleagues were saying earlier that they were having trouble understanding what I was saying. It's called the enthalpy principle. It's a chemical principle whereby you calculate the energy generated by a product, as compared to the energy required to initiate the process…
