13.10.4 Availability of Alternate Energy for Irrigation and Its Cost
Availability of alternate energy for irrigation and its cost is a major factor influencing
the use of renewable energy.
13.10.5 Alternate Use of Renewable Energy
If there is alternate use of renewable energy from where the farmers may achieve
higher return, will be easily motivated to that direction.
13.11 Renewable Energy Commercialization: Problems
and Prospects
The need for community support for renewable energy is clear. Several of the tech-
nologies, especially wind energy, but also small-scale hydro power, energy from
biomass, and solar thermal applications, are economically viable and competitive.
The others, especially photovoltaic (silicon module panels directly generating elec-
tricity from the sun's light rather than heat), depend only on (how rapidly) increasing
demand and thus production volume to achieve the economy of scale necessary for
competitiveness with central generation. In fact, looking at the various sector mar-
kets in early 2003, it is probably not over-optimistic to conclude that the lion's share
of remaining market resistance to renewables penetration relates to factors other
than economic viability. This should be seen against the rapidly improving fiscal
and economic environment being created in the EU both by European legislation
itself swinging into full implementation and the Member States' own programs and
support measures, which despite the short-term macro-economic background, are
accelerating rapidly.
The problems (constraints) associated with the renewable energy commercializa-
tion and popularization are
•
cost
•
market size
•
fluctuating energy supply
•
aesthetics
•
environmental and social considerations
•
land area required
•
incapability of generating large amount of energy
•
reliability
•
longevity issues
•
sustainability
•
transmission
