Our tides provide a predictable source of renewable energy
Tides provide stable, predictable renewable energy sources which can compliment other less predictable sources like wind and solar. As this CNN video shows, costs are dropping for these technologies, with this report noting US$0.3 cents per kwh, which is lower than large-scale solar in the US.
As the world's largest island continent, we should be harnessing the natural energy bounty that surrounds us. Mako (https://www.mako.energy/) is a member of the Australian Ocean Energy Group (AOEG) (https://oceanenergygroup.org.au/), an industry cluster, working to commercialise wave and tidal tech.
"We have the lowest energy costs in a zero emissions world and it becomes an advantage in processing Australian minerals. That can become a huge industry.We also have big advantages in our huge areas of land for capturing carbon in plants, in the soil, exporting carbon credits, growing biomass for industry because we won't be making plastics and petrochemicals out of oil, gas and coal, we'll be making them out of biomass and if we get our act together we can do that more cheaply than others."...https://www.abc.net.au/7.30/what-will-the-post-covid-economy-look-like/13194362
