Topic problems

1.Competitiveness of REfossil fuelsand their conventional consumption technologies is

lessexpensive than REtoday.

2.Little amount of independent REproducersand small enterprises.

3. Lackof stable government support and absence oflongterm program

in the REdevelopment in Latvia .


10th June 2009



15/40

As a result insufficient development of appliedresearches in RE

and market oriented design of REecotechnologies,

e.g.wind and solar energy conservation and

balancing systems.

4. Incomplete information for employers on RE

resourcesand their exploiting technologies .

5.Insufficient number of specialists .

Education in RE in LatviaNoone university in Latvia has special study programs

on renewable energy

they do not prepare specialists in RE .

Study programs in environmental sciences have

6universities, but

the study courses in renewable energy are

offered only in three Universities :

At the moment the best way for Latvia is

significantly to supplementexisting study

programs with deepened special courses

and modules in RE physics and

engineering

to provide young specialists with

theoretical and practical knowledge in the

RE, necessary for successive work on RE

problems

It is necessary :-Tostimulate higher and technical education in RE,

and to

prepare specialists for RE

industry .

-To work out education materials ,textbooks specially

for REoriented target groups .

-Toencourage progressive teaching methods toprovide

linkage between education and REindustry.
