We will never run out of power to supply and deliver energy across the world for years to come. We have experience in hydro, natural gas, coal and renewable energy power generation facilities and substations. Power generating systems are generally treated as heat engines to convert heat input into work, hence to produce electricity at a sustained rate. Heat input is supplied by burning fossil fuels (coal, oil and natural) and biomass, or processing nuclear fuel, or harvesting thermal energy from renewable energy sources.
