- See how marine and hydrokinetic technologies harness the energy of the ocean's waves, tides, and currents and convert it into electricity to power our homes, buildings and cities.
this was great for my assignment, thank you
Please see the "Rock n roll wave energy device" developed in India. It has all the attributes for a good technology. It is still in development for want of resources.
Why don't they have a combined wind and underwater marine turbine. The offshore wind farms should also have on the same post an underwater turbine/fan since the structure for the wind farms are already there
Our teacher showed this to us today :3
Kawaii Kat me too!!! but yesterday
cool stuff, fam. thx.
I am researching Marine and Hydrokinetic Energy, and this video is great. Got any ideas that i can add to my presentation?

W video
AWESOME!!!
Marine Hydrokinetic energy is a very predictable energy application. Clean and Green. Wave, Tidal; and Run of the River Hydro in river drainage to oceanic bodies may all contribute to our National Renewable Energy Portfolio.
GOD bless Earth Science textbooks from the College Of dUpAGE
If want to protect ecosystem's fish, our suggestions had better establish artificial fish pond to carry on artificial aquaculture.

you're the U.S department of energy and you can't at least get 1440p HD for your videos?
👍👍🇺🇸🇵🇭🇺🇳👌
I think this stuff is irrelevant
Propaganda. This is a sales video, not introductory MHK presentation. We need electricity 24/7. The output from any MHK device other than tidal, varies greatly with the seasons and thus requires traditional (fossil fuel!) power plants to kick-in when production is low. Fossil fuel generating stations operate 24/7 and are down only for maintenance. Every 10 MW of MHK power probably requires and additional 5 MW of conventional power to keep the juice flowing 24/7. The combined cost is prohibitive.
Not really.
- We need electricity 24/7 - electricity demand is much lower at night than during the day. Conventional thought is that we need energy production that matches our consumption patterns. Solar works well for that since it produces when we use it. However, a better paradigm is using electricity when it's produced, such as storing thermal energy for HVAC when excess is produced / costs are low and then using that stored energy later when less is produced / rates are higher. A similar application is charging EVs when there is excess generation. Such events are forecasted, and EV owners can be alerted to charge their cars at the appropriate time(s).
- Intermittent production - Yes, each individual source is intermittent, but like an investment portfolio or diet, diversification reduces a lot of the variability. Wind doesn't always blow, but it is almost always blowing somewhere. Wind on land and wind at sea generally peak at different times. Wind and solar don't peak at the same time. And with either the paradigm shift of using when produced instead of producing when used or improving energy storage (such as pumped hydro), the overall variation in production can be managed.
- Fossil fuels are required - No, just an on-demand energy supply is needed. It can be hydroelectric (including pumped hydro storage), geothermal, or nuclear.
