I've been hearing a lot about the new "green" energy sources. What are they and are they safe?

The most common “green” energy sources are wind, solar, geothermal, and biomass. Wind is generated by rotating turbines that convert wind energy into electricity. Solar panels use sunlight to generate electricity directly. Geothermal energy comes from the heat of the Earth's core, which is used to generate electricity through steam turbines. Biomass refers to any organic matter such as wood, plant material, or agricultural waste that can be burned to produce energy. All these sources are considered “green” because they don't produce pollution or greenhouse gases when used. They also offer many other benefits, like creating jobs and reducing dependence on fossil fuels.
