The document discusses different energy sources such as fossil fuels, wind turbines, and solar panels. Fossil fuels release carbon dioxide into the atmosphere while wind turbines and solar panels do not pollute but have disadvantages of taking up space and not working without wind or sun. The consequences of global warming include wetter winters, warmer summers, melting ice caps which endangers Arctic and Antarctic animals. Individuals can help by recycling, conserving electricity and water, and not wasting energy.
