Is Ocean Energy More Trouble Than Its Worth?

The video discusses the potential and challenges of marine power, focusing on wave and tidal energy. Wave energy faces significant hurdles due to harsh environmental conditions and economic setbacks, while tidal stream energy shows more promise. The video compares these with other renewable sources like wind and solar, highlighting the difficulties in making wave energy viable. The future of tidal stream energy looks promising, but wave energy may take longer to develop.

What are the two main types of marine power discussed in the video?

• Solar power and wind energy

• Wave energy and solar power

• Tidal stream and wind energy

• Wave energy and tidal stream

Why are wave energy companies facing difficulties according to the video?

• Because of a typical capitalist shakeout

• Because of the harsh environmental conditions

• Due to lack of interest from investors

• Due to the abundance of tidal stream energy

Which renewable energy technologies have become cheaper and set an example?

• Wave energy and tidal stream

• Onshore wind and solar

• Nuclear and hydroelectric

• Geothermal and biomass

What is one of the main challenges for marine energy technologies?

• Competition from fossil fuels

• Lack of energy resources

• Incredibly harsh environmental conditions

• High population pressure

What is the potential future of tidal stream energy according to the video?

• It will be replaced by wave energy

• It is expected to decline in importance

• It could emerge as an important market in the next 10 years

• It may not be significant for another 20 years
