Presentation Transcript

  • There are many renewable energy sources that are alternatives to fossil fuels, but some are not without controversy.

  • For instance, nuclear power is used to generate about 25 percent of the world’s electricity, but it has inherent risks, especially in the disposal of radioactive waste.

  • In our everyday lives, we can also work to conserve energy. which draws upon the earth’s natural heat, and biomass, which produces an alternative to gasoline, are being considered in the movement away from fossil fuel dependence.

    • Insulating, turning off lights and only using appliances like dishwashers when they are full are just some of the ways people can limit energy use in their homes.

    • Also, carpooling, bicycling, and taking public transportation are effective energy-saving ideas.
