What are the pros and cons to water wheel energy?

Answer 1

There are really few disadvantages to wave energy, save the fact that the locations are very few and limited in terms of possible size of equipment. It is a true green energy with no carbon dioxide emissions.

Answer 2

PROS:

• Dams can store rain water or water directly from the river itself. Then, in case of a Drought, the dam will still have a relatively constant supply of water.

• Producing Power.

• Controls flooding & provides recreational activities such as boating fishing and swimming, if the lake is not being used for drinking water (Dam Society).

• Simple design makes for inexpensive repairs and maintenance costs (Dam Society).

• Produce inexpensive (after completion) and clean power.

• Renewable energy source, because the water is not destroyed by passing through the dam.

• If needed, dams can be shut down instantly, where thermal plants take hours, and nuclear plants can take days! (Dam Society).

• Very few breakdowns.

CONS:

• Hydroelectric power production require flooding of entire valleys and scenic areas.

• Disrupts natural seasonal changes in he river, and ecosystems can be destroyed.

• Ends flooding that help to clean out the silt in rivers, causing them to clog (Energy Laboratory).

• The silt that usually flows down to the Beaches and Estuaries is block by the dam.

• Studies show that the plant decay caused downstream of major dams produces as many greenhouse gasses as more conventional methods of producing electricity.

• Dams are expensive to build, and due to drought may become useless, or produce much less power than originally planned.

• A dam being build in Quebec will end up flooding an area as large as Switzerland (Energy Laboratory).

• Dams can break in a massive flash flood.

Answer 3

what are the pros and cons of water wheels

Answer 4

they produce loads of energy and you can't really see them in the see, they will stop if there are no waves.

Answer 5

if everyone flushed the toilet at the same time. we would all drown in urine
