    Too funny! They have me Bugged.. Just got an email from edison re: power shut offs. Part of it.... JR

    "SCE also implements Public Safety Power Shutoffs (PSPS) as a measure of last resort to reduce the threat of wildfires. During the last wildfire season, we know that PSPS had a significant impact to our communities with some customers experiencing multiple PSPS outages. We are committed to reducing the use and impact of PSPS to our customers.

    Thank you,

      Going back to the start of the thread "excess solar generated power", thats the problem, we are nowhere near that point.

        Maybe not a scam, but certainly a lot of fluff. & buzz words. Never mentions a working prototype system. And there would be no innovation in such a system - just stringing together at-hand technologies. I.e., nothing to create a competitive advantage.

          Walmart has already been using hydrogen power:

            We have been using solar electric power generation in NZ for more than 100 years and it still accounts for the majority of electricity generation in this country.

              That is easy to do. For a total population of 5 million. The State I live in (calif) has 40 million people. Just one state. Heck, Alabama has as many people as NZ.. JR

                That battery is made in Vietnam. Im not sure I will be buying a battery thats made in Vietnam. No offence intended to the great people of Vietnam. More to the issue of quality control. Not always great to buy the least expensive electrical devices. JR

                  Ah, but earlier this week I saw an item in the SF Chronicle that for a short time (hour or two in the afternoon) California (the whole state) was running 100% on renewable power. Solar, wind, and I suppose hydroelectric.

                  So what'll we see in ten years?

                  There are no stupid questions. But there are lots of stupid answers. This is the internet.

                    I didnt see that one. That is significant seeing how Calif. has a large population but also a large manufacturing base which probably uses more energy than the people themselves.

                    Also, I wanna make sure I was not diminishing what NZ is doing, very commendable.. What did surprise me was the 100 year point. I had no idea solar was around for that long. And that they dont use wind as the primary power generator. I thought it was windy there JR

                      Hydro power is solar power. Wind power too is of course solar. I suppose one could say oil and gas is stored solar energy but not nuclear which is energy left over from the creation of the universe.

                      Wind power is about 6% of NZ power production.

                        I bet that is an old picture, and that they are made in China.
                        I just went through trying to replace a bunch of the ubiquitous 12v SLA batteries, and in looking at actual descriptions, they were virtually all made in China or India. I don't have a particular problem with them being made in China, but the quality control is often quite hit or miss, and I very much avoided any made in India.
                        I have used many that were made in Vietnam, and have had very good luck with them - so they are now my preferred country of origin. Go figure.
                        I didn't even see anything made in any western countries, but if I had, seriously doubt that I could afford them, or that they would be cost effective in any way (factoring life vs cost).

                          Are you sure about that part of Solar ? Not to be argumentative, but how was it done before say 50 years ago ?
                          My understanding is that NZ has huge Geothermal assets and along with Hydro-electric , you have a lot of natural energy, but still use gas turbines in some instances
                          I have no idea about wind or solar - Had a friend work there 30 years ago

                            Hydro and wind power are both solar, the sun shines and makes the wind blow and the rain fall.

                            Natural gas reserves in NZ are not great and will probably be gone by 2050. Yes, geothermal with a few areas well supplied with natural heat and geothermal power providing about 17% of electricity.

                              By no stretch of the imagination can Hydro electric be called solar, nor can wind. We are discussing solar PV or electric here directly sourced from sunlight. Yes there are solar water heaters used where you folks have warm sunshine year around.

                                Furthermore, there were no practical solar cell one hundred years ago.
