Pros:
Wind Power:
There are many pros for using wind power. Creating energy from wind is very
inexpensive these days (compared to other sources of energy) Wind turbines can be
very simple (which means very affordable) and could still generate a good amount
of energy.

Solar Power:
With global warming, and the Earth getting closer to the sun year after year, this
is considered a very important way of creating energy. Solar technologies are
broadly characterized as either passive solar or active solar depending on the
way they capture, convert and distribute solar energy. Active solar techniques
include the use of photovoltaic panels and solar thermal collectors to harness
the energy. Passive solar techniques include orienting a building to the Sun,
selecting materials with favorable thermal mass or light dispersing properties,
and designing spaces that naturally circulate air.
Pricing for example is an excellent pros for this energy. Average pricing
information divides in three pricing categories: those buying small quantities
(modules of all sizes in the kilowatt range annually), mid-range buyers (typically
up to 10 MWp annually), and large quantity buyers (self explanatory—and with
access to the lowest prices). Over the long term—and only in the long-term--
there is clearly a systematic reduction in the price of cells and modules. For
example in 1998 it was estimated that the quantity cost per watt was about
$4.50, which was 33 times lower than the cost in 1970 of $150.
Wave Energy:
Traditional sources of energy such as oil, gas, and coal are non-
renewable. They also create pollution by releasing huge quantities of
carbon dioxide and other pollutants into the atmosphere. In contrast,
waves are a renewable source of energy that doesn't cause pollution. The
energy from waves alone could supply the world's electricity needs. The
total power of waves breaking on the world's coastlines is estimated at 2
to 3 million megawatts. In some locations, the wave energy density can
average 65 megawatts per mile of coastline.

Geothermal Energy:
Geothermal energy is the heat from the Earth. It's clean and
sustainable. Resources of geothermal energy range from the
shallow ground to hot water and hot rock found a few miles beneath
the Earth's surface, and down even deeper to the extremely high
temperatures of molten rock called magma.
