ADVANTAGES AND DISADVANTAGES OF USING FOSSIL FUELS ØDecide which statements are advantages and which are disadvantages. Explain why. • Very large amounts of electricity can be generated • Non renewable: Their supply is limited and they will eventually run out (finish) • Cheap energy resources • Easy to transport to the power stations • They release carbon dioxide (CO 2) when they burn (greenhouse effect and global warming) • Gas-fired power stations are very efficient • A fossil-fuelled power station can be built almost anywhere • They release sulfur dioxide gas when they burn (acid rain) Susana Amorós
