You seem quite upset about my posts which contain valuable information aimed at trying to advance a real solution to our energy/climate change issue. You make unfounded accusations yet do not provide any useful information of your own.

I am an environmental & process engineer and I do work on all kinds of energy projects so I have no special allegiance to coal-fired energy. If you had read all my posts you would know this.

The basic problems with using wind energy to replace fossil fuels are the following:
- Low and erratic availability (22-26%)
- No practical means of storing the energy on the scale required if wind energy becomes more than the minute portion of our energy production it is now.
- Extremely expensive capital costs/kwh compared to other energy production methods (more than triple coal/gas generation). This makes wind projects non-profitable without massive government subsidies which means no private investments.
- Short equipment lifespan compared to conventional energy production equipment.
- Currently requires back-up through conventional fossil fuel generation, such as NG combustion turbines, making the net GHG emission reduction quite small.

If you want to contribute in a useful manner please tell me how you address the above concerns.

In regard to my comments on hydrogen production you completely misunderstood my position. I suggested that future large scale hydrogen production was one of the potential means by which we could store energy produced by non dispatch-able sources such as wind and solar and make them viable. If hydrogen could be produced and stored at the wind generation site and then used to power fuel cells to produce power when the wind dies down the erratic nature of the wind energy could be overcome, contrary to the current method which consists of firing up NG gas turbines to replace the missing wind power. If you want to say that this is not currently viable then I will agree and tell you that’s why there is no useful application of wind-energy on a large scale today.
