    It is currently illegal to resell electricity that you generate using 'waste'.

    So say you run a heat-treat process. You don't have much incentive to install a way to reprocess that heat. I wish I could remember the TLC/Discovery/History channel special that they had about it...

        Depends on your viewpoint. Waste heat from electronics is just the energy your purchased with it's form converted. If you convert it BACK to electrical energy, you could be considered to be REselling it. This is opposed to hydro, geothermal, solar etc where the original form was never actually purchased. Coal, nuclear, etc might still be considered "reselling" even for the power company though since in those cases you do buy a material with stored energy.

        Either way though, pointing out these differences is just being a pedantic ass, but I suppose turnabout is fair play.

      What? You better tell that to the thousands of dumps across the country burning 'waste' methane to produce electricity to sell.

      Many industrial facilities also produce energy from waste heat and manufacturing bi-products. It's called co-generation. For example, many cement manufacturers burn natural gas (among other things) to produce lime-ash. They take the waste heat and produce steam to turn generating turbines, often producing more electricity than they use.

          I simply read it as: they burn more natural gas for lime-ash, using the heat from the lime-ash process to turn turbines. This generates more electricity than is required by their day to day operations. Thus, more electricity than they use. The excess electricity is then sold. Nothing there violates your sacred law. I think you just skipped over the part about burning natural gas.

            Correct, especially when the natural gas could be contained within the limestone itself, thus unlocking it during processing. It would technically be possible to have more energy unlocked than it took to unlock it. However, it still took as much energy to put it there in the first place, however that was all done by biological and geological processes millions of years ago.

            • No need to come up with more examples. It's possible to make any industry produce more electricity than it generates as long as it uses an energy source other than electricity, or someone else is expending the energy on your behalf. For the former, just hook your machinery up to enough windmills or waterwheels to fully power it, then use any excess kinetic energy to drive a turbine.

            It may cost more up front to install the equipment, and it may cost more in a typical 3- to 5-year ROI, but over the long term the costs should be lower unless the maintenance and repair costs dominate.

      I'm curious how you think this could make them energy negative. The entire article was about the face that they have multi-year contracts to lock in their rates, and previously they either had to overlap the contracts (i.e. purchase something they're not using) or pass on good deals. Nowhere do they discuss generating extra electricity themselves, just reselling electricity that they aren't using.

      OP is technically correct but its a massive simplification, and not a serious problem for an organized well run company.

      It has to do with depreciation and losses. If IBM writes off an ancient server and sends it to the scrapyard, they don't have to pay any property tax on it anymore and can deduct the value of the server off their profits and balance sheets. Its a simplification, but you don't have to pay tax on a loss of money from giving up and scrapping that server.

      This applies to pretty much any industry. Let say you're a sawmill. And your accountant deducts the value of some screwed up scrap wood, so you don't have to pay tax on that wood anymore, or at least it offsets the gains/profits that you do have to pay taxes upon. Then, dude installs a cogeneration plant, burns the "worthless" scrap wood, and gets money for it. Unless they tell the accountant/IRS that wood is now a profit center instead of a loss center, big tax problems can develop. Its also complicates the situation if some "valuable" wood is freely given away in the trash can, and some is burned for profit, because its a money laundering/theft/fraud opportunity.

      This is one line of thinking that leads to scrapped computer equipment being pushed thru a chipper shredder to make sure no one can ever use it again.

        I'm an accountant, have read your post a few times, and still can't figure out what you're trying to say. (caveat: this post assumes U.S. tax law)

        "If IBM writes off an ancient server and sends it to the scrapyard, they don't have to pay any property tax on it anymore and can deduct the value of the server off their profits and balance sheets."

        (1) IBM probably doesn't pay much, if any, property taxes on server equipment. (state and local taxes on the current market value of installed equipment)

        (2) IBM has already deducted the cost of the server equipment from their U.S. income tax return as a depreciation expense - for such small costs, it is immediate-to-very-quickly. Scraping equipment results in a tax benefit only when you have not already 'written off' the cost of the equipment on a tax return, which tax accountants do as quickly as allowable.

        (3) Similarly, IBM shows server equipment on their balance sheet as 'equipment, net of depreciation', that is, the un-depreciated (or not-yet-'written-off' portion of acquisition cost). Scrapping already-expensed or fully-depreciated equipment generally doesn't change the balance sheet that much. (there are tax vs. book differences in depreciation and expensing equipment, but minor in the great scheme of things)

        ----------

        As to the Sawmill example:

        The entire plant is Revenues minus Costs = Profit. You bought the input wood, and produce wood products for sale. You deduct, as Cost of Goods Sold, all of the input wood as raw materials. If you previously threw away waste sawdust, that is your inefficiency, but doesn't change the fact that you would still deduct the full cost of the wood raw materials.

        If you start selling the waste sawdust, then you still deduct the same amount for the cost of raw materials - you bought the same amount of wood. Only now, you are selling another product for additional revenue, which used to be thrown in the trash. That the sawdust used to be thrown in the trash isn't what caused those taxes to be lower - it's that you didn't have as much revenue (and profit) which caused the lower taxes. Now that you are selling the sawdust: More Revenue, same Costs = more Profit due to a better sales model. More income taxes are owed as a result of the increase profit, not because you sold product out of a loss center (profit and loss center are not tax terms; they are used in management/operational accounting), or used to record some deduction for throwing the sawdust away (you didn't record any such deduction, you simply didn't record any revenue from the (non-existent) sale of the sawdust).

        There would be regulatory and special tax depreciation considerations if you are burning sawdust to generate electrical power for sale, and there might be a difference in how you would characterize and value a charitable contribution of sawdust in the two scenarios (due to differing evidence of value of the contribution), but those are both sidepoints to the main topic of characterizing the sawmill's economic transactions for tax purposes.
