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

The most popular “green” energy source is solar power, which uses sunlight to generate electricity. Solar power is considered one of the safest forms of renewable energy because it does not produce any emissions or hazardous waste. Wind turbines are another popular green energy source that use wind to generate electricity. They are also generally considered safe as long as they are properly maintained. Biofuel is another type of “green” energy source that produces energy from organic materials such as plants or animal waste. This form of energy is considered sustainable because it can be produced in a way that doesn’t deplete natural resources.
