energy is a term that incorporates many different technologies
and techniques for harnessing the energy and potential power
that exists all around us in nature.
are four types of alternative power; solar power, hydro electric
power, wind power, and nuclear power.
Each are particularly
promising for a variety of reasons, and could become the dominant forms of energy production in a generation or two.
power comes from the harnessing of the sun's energy.
The sun is the biggest source of energy in our world, and
all other forms of energy on Earth, with the exception of
energy, originate with the sun.
In fact, the entire
energy consumption needs of the planet for an entire year
are produced by the sun in just one hour, which makes the
sun a massively untapped alternative energy resource.
Hydro electric power is power produced by the movement of
water. The most obvious and common form of hydro electric
power is dams, but energy can also be taken from the force
exerted by tides and deep sea currents. Because hydro electric
power is so easy to tap in to, it is the most common type
of alternative energy production today.
Alternative sources not only
mean clean, sustainable
energy, but green jobs to
help power the economy.
is power generated by a wind turbine. Wind power is a relatively
under-used form of alternative energy, but it is growing rapidly,
in part because wind turbines require little maintenance,
have such a tiny footprint, and do no real harm to the surrounding
Unlike other more environmentally friendly forms of alternative
power can potentially be an extremely toxic undertaking,
and is a hotly debated subject.
point out that nuclear power reduces carbon emissions and
technological developments are reducing the amount of toxic
waste produced while also making nuclear power plants more
meanwhile, counter that nuclear waste may often be not properly
disposed of and - perhaps more dangerously - that nuclear
materials can also be used for more insidious purposes than
The future of alternative energy
the hunt for alternative energy has taken many forms such
as research into man-made cyanobacteria (also known as blue-green
algae) that has also shown much promise.
passing day, more and more experts are predicting it will
be in the not-too-distant future when alternative energy may
evolve rapidly from the drawing board to urgent real-world
world waits and watches, keep an eye on which of these alternative
sources may rise to meet the planet's energy needs as coal
and big oil once did.
