The fear of global warming has led to some interesting
alternative energy ideas for the future that would
have less impact on the environment. Constant research
takes place daily for sources of energy that utilize
our natural resources, have little repercussion on our
atmosphere, cost less and are naturally renewable.

There has been much research in the area of solar
power, tapping geothermal heat inside the earth,
harnessing the power of the tides as an energy sources
and wind turbines, but scientists are going further
into their imaginations to develop energy from sources
never thought of before.

For instance; scientists are studying marine algae in
the hopes that they could generate power from the
methane given off by rotting algae; the methane could
then be harnessed to provide methane for burning to
power industrial needs for energy. Corn is being
tested as a fuel (ethanol) for cars, as well as home
heating sources, and there are many other areas that
you may not have thought about.

Early studies are looking at falling rain and how it
might be used to generate power (same premise as
harnessing wave power). I
