Power generation in a post-nuclear and post-fossil fuel age is one of the key challenges facing the world. Climate change and geopolitical tensions are forcing an increase in investment in alternatives. While wind and solar power offer the most environmentally sustainable option, they cannot meet demand fully. There will always be a need for fuel-based heat and power generation. The sustainable options here include waste-to-energy units and biomass plants. In a market leaning ever further towards renewable fuel sources, energy utilities are turning increasingly to companies like Leroux & Lotz Technologies SAS in France.
