[...] Tidal and wind power is incredibly expensive. There is a good reason why tidal and wave power has not taken off like solar and wind – it’s too expensive. A report by infrastructure consulting firm Black and Veatch says that wave and marine current power generation can cost as much between $410 – $445 per megawatt-hour, while other renewables like wind, solid biomass, hydroelectric and geothermal have costs nearing $150 per megawatt-hour.

Here in NZ we had big headlines in the newspaper yesterday about water being spilled from hydrolakes as demand has decreased and we had too much rainfall.
“During May, the inflows into South Island hydro lakes were among the highest recorded and storage nationally was 1.36 times the historical mean”.
Still, we are paying the usual prices and the gas fires are still running……

Biomass electricity is also constant, so does not require any fossil-fired backup. As a baseload source, biopower is also cost-competitive with new coal, and less expensive than new nuclear.

Where I live in the Southeast, we have massive potential for renewable electricity from biomass. This must be why the utilities are fighting it so hard: It directly threatens their existing business model of very large, highly centralized new coal and nuclear plants.

"wave and tidal CAN cost as much as". There are no commercial scale plants yet just a few test stations, we are just at the beginning of this technology. Ocean currents are constant, so it could meet peak demand.

but are there any other alternatives or ways which we can use or carry out rather than using those conventional energy source, i actually thought for a developing country like namibia its very good to have those rather than asking for help from our fellow counterparts.
