    The Falling Costs of Renewable Energy

    The Falling Costs of Renewable Energy

    Historically, cost was cited as one of the primary barriers to switching from fossil-based energy sources like oil, coal and gas to renewable energy sources like solar, wind and geothermal.
    But the narrative has now changed. Plummeting costs for renewable energy technologies are making a global energy transition not only possible, but actually less expensive than the alternative.
    So, let's subsidize coal.

    OK

    The world currently subsidizes fossil fuels to the tune of more than US$500 billion a year, dwarfing support for renewable energy by a factor of five.

    And this is why those coal jobs simply aren't coming back.

    But, we'll be on oil and natural gas for a loooooong time.

    Far past our lifetimes.

    But green energy is getting better and better.

    I'll be glad when it becomes economically feasible for me.

    Economics is the key for many Americans.

    Make it cheaper than petro energy and we'll go to it.

    Solar electricity is cheap. Much cheaper than the power grid. I know as i have solar and am very happy i get no surprise electricity rate increases or even a bill.

    We need to start thinking outside the box with some of these new systems, Solar, in particular.

    WIND power is great, but, probably not feasible in more urban areas (Although....if a wind turbine is placed in the right position---ANYONE who has lived in a city, can tell you how strong air flow can get in between certain buildings. In fact, I think all of that is taken into consideration when the structure is designed....)

    SOLAR panels of all sizes, can go....EVERYWHERE (at least, every where you do not wish to "shade" with the panels themselves). Roofs, on the sides of Highways/interstates, on the SIDE of many buildings, Auto Rooftops, etc.)

    Geothermal seems like a great idea, and I can't think of any limitations, other than cost, and PERHAPS that some ground soils may not be fitting for what ever reason (ie, would it work in Southern California? On the one hand, you probably have GREATER energy sources under Southern Cal, but, due to so many Earthquakes (many of them very small), I am wondering if the ground, itself would not 'cut' many of the geothermal ports...???

    But, what we REALLY need, are not better ways to HARNESS energy, but, to STORE it, and send it through the GRID. This is where we lose an immense amount of power.....

    Coal still has a purpose, and we should keep with it, but...it is dirty, and there are better systems.

    A friend of mine works for an Energy Company, and he specializes in Coal power plants. Basically, he is often "on call" for emergency energy spikes in usage, or if another NON coal plant has to be taken down. He told me that most of the Coal burning plants are for redundancy. He (and his team) may be called to work, in which they "reopen" a mothballed Coal Plant, start her up, and put out energy, until the need is over. Then, they clean it all up, mothball it, and, prepare it to be re-opened, when needed. In between, his company has he and his team do all sorts of other duties.

    Eventually, we may not even need that, but it would be CRAZY to destroy all of our coal plants, because we have an IMMENSE coal reserve.

    What would greatly help Coal MINING jobs, would be to find other uses for the coal. (People often forget the multitude of uses we have for things like Petroleum, OTHER then just energy production...)

    You made me do some research and I found this article. But even doing what is suggested in this article won't bring back a substantial number of coal mining jobs.

    Maybe on a remote island in the Caribbean, but not true in the continental US.

    Whut?



    I have noticed a substantial increase in the number of houses with solar panels on them in just the past couple of years.

    I looked at going solar a few months ago. A system to meet my needs with out storage was $50,000 and that would save me $2,000 a year in electricity. Solar PV is cheaper than it was, but still much more than fossil fuel generated electricity.

    It is very expensive to generate electricity on islands, so solar PV is economical in those places, while electricity is cheap here in the US.
