Type of energy 3D Model or Animation Renewable or non-renewable? Why? How is electricity generated? Advantages (3) Disadvantages (3) Sustainability (Real example) Energy demand in Colombia Coal Coal is non-renewable because it takes millions of years to form and does not regenerate on a human scale. The coal is pulverized and burned in a boiler to heat water, generating high-pressure steam that drives a turbine connected to a generator, transforming mechanical energy into electrical energy through electromagnetic induction, while the combustion gases are filtered and released through the chimney. High energetic power (a lot of heat per ton). Low cost (economical compared to other sources). Global availability (reserves in many countries). High environmental impact (significant emissions of CO₂ and other atmospheric pollutants). Low energy efficiency (only uses between 30% and 40% of its potential). Public health risks (contributes to respiratory and cardiovascular diseases). The Cerrejón mine in Colombia is the largest open-pit coal mine in Latin America, with an annual production of 25 million tons, operated by multinationals and subject to environmenta...
