    Here's what it will look like:

    The country will desperately need greater utilization of Solar Electric Power in the future, as more controls are placed on the burning of fossil fuels....(my comment).

    "The race to build the world's largest solar power-plant is heating up. California-based energy company Solar Reserve announced plans for a massive concentrated solar power(CSP) plant in Nevada that claims to be the largest of its kind once built."

    "Solar Reserve CEO Kevin Smith told the Las Vegas Review-Journal that the $5 billion endeavor would generate between 1,500 and 2,000 megawatts of power, enough to power about 1 million homes. That amount of power is as much as a nuclear power-plant, or the 2,000-megawatt Hoover Dam and far bigger than any other existing solar facility on Earth, the Review-Journal pointed out."

    Solar Reserve's Sandstone project involves at least 100,000 mirrored heliostats that capture the sun's rays and concentrates it onto 10 towers equipped with a molten salt energy storage system. The molten salt, heated to more than 1,000 degrees, then boils water and creates a steam turbine that can drive generators 24/7."

    I spoke disparagingly about this type of Solar Power gathering in earlier discussions. Currently operating plants using this technique on a much smaller scale are killing birds, perhaps thousands annually.

    "The Center for Biological Diversity hired biologist Shawn Smallwood to estimate bird mortality at the Ivanpah plant. In what he called a "back of the napkin" estimate, due to limited data available, Smallwood arrived at 28,380 bird deaths per year caused by Ivanpah" (Ivanpah is an already-operating facility). This:

    is a photovoltaic solar plant being built only three miles from our home! It contains no mirrors, no concentrators of heat, or transmission of it of any kind. The Electric Power is produced directly from Silicon Solar Cells mounted on pivoting supports which "follow" the sun's location as it sweeps across the sky. I had difficulty finding info on it, and have driven over there several times. As I understand it, it will produce about 34 million (mega) watts of electric power. When the sun sets, the cells "rest", though some infrared radiation is available during the night, hardly any power will then be generated.

    THIS is the right way, IMO. Frank

    We are dreaming of a power source that is purely clean energy with solar, wind and geothermal. If we have the technology, I wonder what's keeping our governments from using that knowledge? I know that we have several wind power farms here, not just 1 or 2 but in several provinces where the most popular is the one in Ilocos Norte which is the project of the governor who is the daughter of our former president Marcos. With the solar, there is no solar farm here that is substantial in size. All I have seen are farms with several solar panels only. From our own research, the main issue in solar energy is the battery which is the storage of the collected solar power. And until the technology of the battery is not improved then solar power will not be economical.

    Corie, here is the part not well understood. Basic differences exist between powering a home using Solar, and using Solar to contribute to the energy available in a large "grid". The home has no way of immediately using all the power produced, so it is "stored" in batteries, or better yet, "dumped" back into the existing grid supplying power there. When that is done, one's electric meter actually runs backwards, creating a "credit" against the home-owner's bill!

    Now, with "Power Plants", those facilities intended to produce power and distribute it, no storage facility is provided. The power they produce is "dumped" continuously into the grid. The "thermal storage" concept above, "preserves" part of the power produced during daylight hours, by "storing" it in the form of heated liquid usually within tanks buried underground. Then, during the night, that stored heat may be released by allowing the hot liquid to flow out of the tank into a heat exchanger, where steam is produced, which drives the electric generators. In the "home storage unit", batteries accept the electric power delivered by the sunlight, and store it for use later.

    Am I too technical? I can try to explain further...........

    @Frank Sanoica, let's just be friends and quit the high tech talk, hahahaaah. I had already said that I have a bad cold which gives me weak knees and a bad cough. I forgot to say I have a headache too and it is getting aggravated by your posts, huh.

    But seriously, we really go for clean energy and we are hoping that in our lifetime, we will live to see solar powered homes, not one or some but all homes in our country.

    We need to look for new power sources. Ween us off dependency for oil and all the problems that come with that.

    Those who strongly oppose renewable energy have the most to gain from keeping the old energy resources, coal and oil. They also have the most powerful voices in governments. I think that's why progressive California leads in renewable energy projects.

    Here in BC, 93% of our electrical power is renewable energy, mostly from vast Hydro dams built in the past. We are fortunate in having a mountainous Province with lots of rivers for hydro dams.

    On a larger scale, Almost everywhere has vast renewable energy potential from wind farms and solar to tidal and wave power. More energy falls on the earth everyday from the sun than we can possibly use, we simply need the will to capture and use it.

    Hydro power is good, yes. It requires a reasonably continuous supply of stored water, such storage being subject to the whims of Mother Nature though. Thus, big reservoirs are necessary, requiring big dams. Big dams hastily implemented have caused disasters. Aside from those factors, the unknowns associated with global warming throw in additional questions. Nonetheless, I strongly support Hydro.

    Tidal and wave power generation have not been introduced on large reliable scale, to my knowledge. Desert sun seems to be very reliable over the long term. Frank
