Comment on Hydro Power; the end or here to stay? by mogens

Yep, you are absolutely right. Regarding California installed hydro capacity; it’s interesting to note that given unlimited water supply, we have enough turbine capacity to provide 50% of annual California electricity usage.

Solar is still an expensive option at the wholesale level, but has tremendous potential. If you were to plaster a app 600 square mile (20 x 30 miles, 30 x 50km) area with today’s standard PV panels, you would on an annual basis generate enough energy to meet the annual California electricity demands. Try to pencil out such a farm on a California map. It’s insignificant. Clearly nobody would in his right mind consider that today, but it tells us of the solar PV potential. This is going to happen. Just let the technology mature.

You are absolutely correct about car batteries which can become a grid stabilizer. As with anything, there’s got to be an economical advantage, and somehow there has to be an incentive for you to participate in this system. Surely no electric car owner would let the utility company charge/discharge ones battery at will given battery degradation per such cycle. With large scale hydro pump-up, you loose about 15% energy per cycle. Thus, for car batteries to be viable, they have to match that loss rate, and hopefully also be able to squeeze out a small profit for the car owner. If not, I just don’t see this happening.

All power sources have dacwbraks. The two you mention, like nuclear, are relatively clean, which is a plus.Hydro is very cheap for the amount of energy we get, but our rivers are basically all dammed up already there isn’t a lot more hydropower we can get.Solar is one of the most expensive ways to generate electricity on a utility scale, but could be the cheapest way to generate electricity on a homeowner scale, at least for many urban homes. Unless one has a stream running through their property to run a water wheel, or strong steady wind, the other choices for getting power are using a gas- or oil-powered generator, or buying retail electricity from the grid. The generator will cost more per kWh over the life of the system, and the grid electricity could be more or less expensive, depending on where one lives. At the moment, the grid is usually cheaper, but not in all parts of the country.
