The
generation of green energy around the houses entails not only the use of
renewable natural resources as power source; green energy must also be
harnessed with as little pollution as possible, preferably with zero pollution.
Interestingly, there is an exemplary form of sustainable energy generation that
uses polluting by-products as fuel – the production of biogas from
biodegradable wastes. This technology is especially famous for its use in farms
and other rural places. Even some urban settlements have used biogas and
similar biomass-related energy sources as a greener alternative for a household’s
power source. This is in stark contrast to the fossil-fueled energy which still
dominates the world’s energy pool.
Biogas is generally a type of
biofuel produced by anaerobic digestion or fermentation of biodegradable
materials, ranging from farm and kitchen wastes to sewage sludge. This characteristic
makes the production of biogas as a green energy source around the houses of
people not only practical, but also immensely environment-friendly.
Biogas is produced through anaerobic
digesters, air-tight tanks that transform biomass wastes into methane. This can
in turn be used for a wide variety of purposes, including heating, electricity,
and fuel for various modifications of the internal combustion engine.
Furthermore, this raw kind of biogas can be upgraded for use as fuel in
industrial machinery. In 2005, world energy supplied by biogas totaled 44 GW, and
another 264 GW for heating.
Overall, the use of biogas as an
alternative energy source proves very beneficial, especially in areas with
livestock or plantations which require the control of biodegradable wastes. It
is very versatile, and a positive investment in the field of providing green
energy around the houses of people around the globe.
In recent years there has been a paradigm shift towards new, renewable energy resources and away from fossil ...
