Geothermal only works in certain places
I never posited that it works everywhere and that wasn't my point anyway.
and wind and tidal (not even mentioning potential damage to local ecosystems by putting tidal generators all over the coastline)
An environmental study should always be done before implementing tidal energy in an area. But, are you implying that the cons outweigh the overall benefits?
Tidal Energy Benefits:
• Tidal Energy is a renewable energy source which means that it does not depend on fossil fuel, does not pollute the environment with CO2 emissions and it is renewed continuously.
• As a renewable energy source, Tidal energy is green since it does not pollute the environment.
• Tidal power plants are more efficient than many fossil operated plants. For example a tidal plant converts into useful energy, electricity, about 80% of the kinetic energy while a coal plant achieves only 30% efficiency.
• Tidal Power plants have a high construction cost but they have low operating expenses, OPEX, and labor costs since they can virtually operate unattended.
• Tidal power plants have a long expected life span, about 75-100 years
we can make breeder reactors now, and if we start a massive shift now
It's a moot point. Nuclear is too expensive and that's why it's on the way out.
