Replacement for Non-Renewable energy
By:Danilo Villaruz
Over the last
three years publicly traded alternativeenergy have been very rolatile with some
2007 returns in excess of 100% some 2008 returns down 90%or more and peak to
through returns again over 100%. In general there are three subsegment of “alternative
energy” investment solar energy, wind energy, and hybrid electic vehicles. Alternative
energy sources which are renewable free and have a lower carbon emission than
what we have how are wind energy, solar energy, geothermal energy and bio
fuels. Each of these four segments involve very different technologies and
investments concern.
For example photovoltaic solar energy based
on semi conductor processing and accordingly, benefits from steep cost
reductions similar to those realized in the microprocessor industry larger
scale higher module efficiency and improving processing technologies. Pv solar
energy perhaps the only energy technology whose electicity generation cost
could be reduce by half or over the next 5 years. Better and more efficient
manufacturing process and new tecnologysush as advanced thin film solar cell is
a good example of that helps to reduced industry cost.
The economics of solar pv electricity are
highly dependent and silicon pricing and even companies whose tecnologies are
based on the materials are impacted by the balance of supply and demand in the
silicon market. In addition because som companies cells on the open market,
this create an irrational pricing environment.
In contrast
, because wind power has been harnesser for over 100 years it undeliying
technology is relatively stable. It economics prices of steel (the largest
componant of a wind turbine) and select composites (used for blades) because
current wind torbines are often in excess of 100 meter high logistics and a
global of competitive advantage. These issues andothers were explored in a
research report by Sanford Bernstein
