twelve reasons to exclude large hydro
from renewables initiatives
governments must reduce non-renewable
energy production, but are large
hydro-electric dams part of the
solution?
Read the 12 reasons why they are not, or
find them
fully explained in the report
(pdf,
419kb).
1. Large hydro does not have the poverty
reduction benefits of decentralized
renewables
2. Including large hydro in renewables
initiatives would crowd out funds for new
renewables
3. Promoters of large hydro regularly
underestimate costs and exaggerate
benefits
4. Large hydro will increase vulnerability
to climate change
5. There is no technology transfer benefit
from large hydro
6. Large hydro projects have major
negative social and ecological impacts
7. Efforts to mitigate the impacts of
large hydro typically fail
8. Most large hydro developers and funders
oppose measures to prevent the construction
of destructive projects
9. Large reservoirs can emit significant
amounts of greenhouse gases 10. Large hydro
is slow, lumpy, inflexible and getting more
expensive
11. Many countries are already
overdependent on hydropower
12. Large hydro reservoirs are often
rendered non-renewable by sedimentation
