CONCLUSIONS
While
there are many options available for sustainable energy
development, they all have some common advantages and
disadvantages, aside from sustainability. All the
methods, with the possible exception of biological
energy, contribute far less greenhouse gases to the
atmosphere than traditional fossil fuels. They tend to
level the playing field between developed nations and
the developing world; since the technology is new for
everyone, no one has to play catch up (similar to
Internet and cellphone penetration in the last decade).
Because nearly every nation can utilize at least one of
these methods, dependence on foreign energy production
is less, decreasing political competition and conflict.

However, all of these methods have one major
disadvantage as well: cost. Because they are newer
technologies, the implementation of renewable energy
sources is extremely capital intensive. Many dams,
barrages, and wind farms take decades to pay off the
initial investment. However, as the example of
wind-energy has demonstrated, improving technology can
drastically reduce the required financial investment. In
time, perhaps all of these options will surpass fossil
fuels as an economic alternative, and everyone can enjoy
the benefits of sustainable energy.
