make electricity or to heat buildings. Finally, biomass
comes from plants, wood, or even waste materials.

energy is important because it helps us use
fossil fuel. Fossil fuels are limited and will
out one day, but renewable sources will always
here. They also create less air pollution, which
cleaner air and a healthier planet.
In the
, more countries will use renewable energy to meet
power needs. It will take time and money
build the technology, but it is worth it.
energy is the key to a cleaner and
world.
