   Well, I say we do …
   Well, I say we do it all, including hydrogen, tidal, natural gas and other methods. We should also double our investment in fusion. I know it seems like a pipedream, but IMHO at this point it’s not a matter of if, but when. And sooner if better than later. I’m a Progressive and I have no problem with fission either. Second generation reactors can now use spent fuel from other reactors, which is a cool development. I’d like as broad an energy portfolio as possible for our country.

   Exactly. Wind and …
   Exactly. Wind and solar make great supplements but they will never be able to provide base load power. Wind turbines are nearing their theoretical efficiency and solar panels may ideally reach 30-40% efficiency, but are still limited by a capacity factor of about 12-20% (~30-40%) for wind.

   Compare this with an average capacity factor of 92% for nuclear power combined with its high power density, and you will quickly see that wind and solar cannot begin to compete with it

   The good thing is …
   The good thing is that “dirty power” is only a startup cost and not inherent in the power generation itself.

   PV cells are …
   PV cells are excellent for desert or dry climates. Notsogood in the Midwest or Northeast. Current solar tech is good for supplementing your power source, not replacing it. There are a few breakthroughs recently, but it’s a matter of getting the right capital to bring these things to market, and we all know how difficult that is, so…

   Good luck powering your home on Solar unless you have lots of land.

   Power output ~250 Watts per square metre. (about 2 to 4 light bulbs). But then you have to figure in night time and cloudy time and morning and night, which will reduce the net output by about a factor of seven (look up “capacity factor”), will give you about 30 w

   yeh it uses nuclear fusion or something? pretty sure humans be trying to make a nuclear fusion reactor by 2035 (so we can have our own little sun on earth) lol

   I just wonder how much DIRTY power (mining, transport, manufacturing, embly) it takes to produce a facility like this, or even a home sized one. Anyone have those figures? How long will it take for this facility to neutralize that?

    Go GREEN or get ready to pay more and more and more…. Home owner generated not Power Company generated. Run your own lives and live free breath easier and for less.

    Why are we not replacing illicit opium in Afghanistan with this “alternative” solar industry? Afghanistan creates 0 kWh of energy and tons of illicit opium.

    Agree wind energy can help too.

    you know how like …
    you know how like there’s no sunlight during cloudy day and night time. and how we also used windmills as a source of energy, why not just create jobs where people’s energy can be used to store energy: muscle powers man. that would be like working out and getting payed at the same time… put that on the list as “renewable energy”… lol.

    one mans conquest is another man liberation. Hawaii is an occuied territory, illegally annexed. It amazes me how some people think history is so one sided, Americas hands are not clean.

    Also, what a silly discussion to have on a video about solar energy

    Not really, most energy we use is released in the form of heat anyway. Look at a light bulb for example - 85% thermal energy (in an efficent one) and 15% light energy.

    These don’t need to …
    These don’t need to turn the deserts into a vast dust bowl, no! And turning it into a giant black field (of PV) is obviously a no no. Using billions of post driven COOL mirrors (without the need to bulldoze) is the final solution to UNLIMITED SOLAR thermal power with heat storage.

    The CPV concept allows thousands of times of the energy production than normal one sun PV. Why? Cause the mirrors extend the rare (such as CIGS material) “range”! CPV is twice as eff as thermal, but needs storage…
