Renewable energy
Wood chips, manure, and garbage are dried
out and compressed into squares called
"briquettes."
Biomass can also be converted into biofuel.
A major advantage of biomass is that it can
be stored and used when it is needed.
Negative aspects of biomass energy
Growing crops for biofuels requires large
amounts of land and pesticides.
Some pesticides could pollute the air and
water.
Biomass energy can also be a non
renewable energy source.
If people do not replant biomass feedstocks
as fast as they use them, biomass energy
becomes a nonrenewable energy source.
Conclusion
Renewable energy is generated from
natural resources. Renewable energy
sources are sunlight, wind, geothermal
heat, water and various forms of biomass.
These renewable sources cannot be
exhausted and they are constantly renewed.
They do not harm the environment. Using
renewable energy you can save your money
and protect the environment.
