    solar and wind power

    I hate to burst your baloon concerning solar and windpower but the facts are as follows:

    The USA has 1049 megawatts of total power capacity. Of that solar and windpower to date has 68 megawatts of maximum capacity.. Broken down further, of the 68, 8.5 megawatts is solar and about 60 megawatts of wind. However you must consider the available capacity. Hydro is nearly 100 %, Coal is 95%, nuke 94%, gas is 92%, solar is 24% and wind averages 15%. So of the 1049 megawatts of total capacity, the hydro and other categories have an average availability of about 935 megawatts. Solar represents only 2.1 megawatts and wind comes in at 9 megawatts for a total of 11.1 megawatts out of 946 megawatts of available capacity. This represents 1.2% of available capacity.

    . The US economy needs power 24/7. It is that simple. Solar and wind are non starters will probably remain nonstarters for our lifetime.

    And if you decide to jump on hydroelectric bandwagon = just remember = hydroelectric power is maxed out and has been maxed out for the last half century.

    The above data was obtained from James Barends who obviously has a pretty good handle on where our power comes from.

    • You obviously do not understand energy. Solar is a on-site distributed gen(DG) resource. Most new solar generation is now rooftop - both residential and commercial. I just installed a 7kw system on my home producing about 14,000 kwh per year. Most of this production(75%) is immediately consumed behind the meter, so there is no record of it for the EIA, my utility, or anyone...All this new solar will not be included in macro data.

      You will start to see this on-site solar DG, in the EIA's macro electric usage for the US - at first you will very low or no growth in electricity demand, then start to see falling demand...This has just started, and with free markets can grow exponentially. The ave. cost of electricity today in the US is .12 per kwh. I produce my own solar electricity for under .06 a kwh. Also solar DG takes the most expensive kwh off your bill making the economic case even stronger...

    • Brawn, he's a propagandist. Facts are irrelevant. He's an Obama and DNC drone. He's incapable of logic and reason.

    • One of the articles I referenced below said we had only 1.1 GW in 2008. Now we have 10GW.
      That is a huge jump!

      To put the numbers in perspective, I pulled up the online 2008 Solar Technologies Market Report from the National Renewable Energy Laboratories (there is nothing like reading an ancient historical tract from five years ago to put the current day’s events in perspective). That report celebrated U.S. cumulative installed capacity in 2008 of 1.1 GW

      • Vivi: Interesting that you only seem to post once a month starting in Dec last year.
        I am honored that you would take the time to respond multiple times to me.
        How many yahoo accounts do you have? Isn't one enough?
        Do you like to hide behind multiple IDs?

        Does it make you feel good to paint the world black and white and seek only opinions that reinforce your bias? Do you watch FAUX news all the time?

        Did you ever find the WMDs in IRAQ?
        Was IRAQ/AFGHAN worth $3 trillion and bankrupting the US?
        What did Bush say IRaq would cost? 2 Billion?

        Why does the US need a $1000 billion defense budget when CHINA only spends $200 billion?

        Is it because there are a lot of afraid little boys that got draft deferrals themselves, real chicken hawks? Are you one of them?

        Since you obviously have some influence with the inner circles of the Obama Administration - please pass along this suggestion.

        Forget solar and forget windpower. Both total losers. Put a bug in their ear. Hamster power. We put super speedy little hamsters into tiny treadmills and run them non stop. My guess is that within several months we will produce more power than solar or wind has produced in the last 100 years

        What do you think????

    • Multiple sites says the US passed 10 GW and will hit 18 GW solar installed capacity by end of 2014.
      These numbers are different than yours. These numbers don't even include wind or water.

      My solar balloon not burst.
      Coal, oil, NG been around long time.
      I am happy with solar capacity growing 10% every year for decades.
      At that rate the solar capacity would double every 7 years.
      You shouldn't feel threatened about coal. Why the worry?

      Improvements in battery storage technology could change the 24/7 power argument. Of course I am in no hurry, I can wait 21 years for batteries to improve while capacity increases 300%. Though I think in 21 years, installed solar capacity in US will be higher than 80GW; the number implied by 10% annual growth from here.

      Here are references from two different stes:
      The US is just the fourth country to pass the 10,000,000,000-watt (10-gigawatt) solar power capacity milestone.

      Solarbuzz notes that solar photovoltaics have been one of the fastest growing energy source in the country over the past six years, growing at over 50% annually. Projected installations for the next year and a half are expected to add another 80%, getting the country close to 18 GW by the end of 2014.

    • Is "available capacity" the percentage of total capacity that is used on average?
