100% clean energy is decades away, I'm not such a pessimist to presume we will have no grid improvements by then. Marketplaces themselves are already straining due to the cheapness of renewables at certain times. Batteries plus renewables will avoid some of this, but overbuilding capacity and demand response with EVs and industry should be another component. I also expect utilities to buy access to appliances and heating and cooling and dynamically control their customers' use.
- whatshisface 7y agoI really, really don't want the power company to control my thermostat. Big companies are invading my home and violating my agency enough as it is. If past behavior is any indication of future behavior, smart appliances are more likely to be snuck in like the phone-home misfeatures on smart TVs than they are to be a willing contract between the home owner and the power company.
- brandmeyer 7y agoThere is another approach that could also alleviate some of the pressure. Instead of keeping the consumer price fixed and allowing the utility to control your load, you can allow the consumer price to float. Most of these markets have a 24hr-ahead clearing price for energy. I think you aught to be able to expose retail consumers to fluctuations based on the day-ahead market to let people make their own choices for energy usage. Given that exposure, enough consumers will change their behavior to soften the variability in price. It might also make distributed energy storage Just Work (TM) if individual battery owners have a vector to profit from supporting the grid.
- nerdponx 7y agoIn the USA I thought the price already floated based on market rates. Yes, absolutely this is the way to go. It works well for gasoline, for instance.
- brandmeyer 7y agoRetail consumer prices don't float in most markets. Some markets have time-of-use pricing for some part of the year, but even those have a fixed peak/off-peak rate that is fixed well in advance.

What prevents an electric company from significantly raising prices for a day to catch people off guard? I can't exactly switch electric companies to punish them.
- benj111 7y agoThe UK can manage to have competing power companies, so its clearly possible.
- Hello71 7y agowhat prevents them from significantly raising rates permanently?
- minikites 7y agoPeople would notice, protest, lobby government for regulation, the usual methods of expressing civil discontent. I'm talking about a situation where people don't notice until after the fact.
- brandmeyer 7y agoThere are other futures markets that are bootstrapped off of the day-ahead market. Weeks/months out are used to schedule maintenance operations. Years out are used to schedule construction/decommissioning. So if the extended market prices are high enough, then this acts as a signal to add generation and/or distribution capacity. Likewise, if the extended market prices are low enough, this acts as a signal to retire capacity that has a higher operating cost/lower profit margins.
- aqme28 7y agoIsn't that basically what Enron did to California? Theoretically they are already doing this, just not to retail customers.

- toomuchtodo 7y agoNest partners with utilities to support demand shedding/load response [1]; you get a utility bill credit for allowing the utility to send Nest demand shedding signals when local power demand is high (which suspends your AC cooling cycle for 1-3 hours), but you can override the thermostat setting if you must (you just don't get the credit). Cheaper than firing up a single cycle gas peaker (super expensive, comparatively speaking to base load and renewables). You don't have to allow the utility to control your consumption automatically, but then you'll be exposed to the real time price of power (not a regulated average as occurred in the past because of dumb meters).

- HeWhoLurksLate 7y agoSo then could I hook up a load to a Nest and have a regular, dumb thermostat control my house and get those credits without actually doing anything? That doesn't seem too hard to pull off.
- grimjack00 7y agoUntil the utility upgrades to the next version of demand response software, which notices that you were sent a control message, but your consumption didn't change, so you're no longer eligible for the credit.
- briffle 7y agoI have this on my nest, and one interesting feature, is it turns down the AC to a lower temp a few hours before the 'energy rush hour' so that your house doesn't get as warm. IE, I have it at 72 deg, a 'energy rush hour' is declared, the nest automatically turns my thermostat to 70 deg an hour or two before, then to 75 deg during the rush hour.

- solarkraft 7y agoThen your electricity will probably be more expensive than that of the people who will utilize the night's cheaper rates and will get rebates for installing a device that will turn some devices down on unexpected peaks. If you still "really don't want the power company to control my thermostat" after seeing your potential savings, that is.
- ThomPete 7y agoIt's centuries away. So much legacy technology and machinery, buildings, installations, infrastructure not to mention the fact that neither wind nor solar and not even hydro are anywhere close to being able to provide that it's only a few percentages of world energy usage and have upper limits. In my view the only real fundamental progress when it comes to energy, within sight (and it's still far away if ever) is Thorium and Fusion. Furthermore the externalities of things like wind and solar isn't calculated today and would make two things very clear. You can't have wind and solar without the backup of oil/nuclear/coal and they will never be able to provide us with enough energy to meet our needs to not talk about meeting our future needs (which will be many times higher than it is today) I am all for green energy but i share your pessimism.
- headcanon 7y agoAt current rate of adoption it may be centuries, but I'm willing to bet that by the end of this century (possibly earlier) there will be a great deal more public pressure to revamp the underlying infrastructure. We could do it in a few decades if we decided to spend the capital on it, its ultimately a question of political willpower. I do agree that fusion would be the ultimate form of power generation and would have the least impact on the current grid. But regardless, the future of energy generation is in diversity of sources.
- ThomPete 7y agoThere already is pressure today to do that. However, I am unconvinced it will actually get done on any significant scale unless there will be fundamental improvements with regards to energy sources. Otherwise, fossil fuels are simply going to be too valuable in no small part due to its multiple applications which none of the other types of energy provides. Otherwise, it will come down to economics. So I agree we will diversify but fossil fuels aren't going anywhere anytime soon.
- headcanon 7y agoHonestly I don't even think it would be as complicated as all that. Its all down to what becomes more valuable. Here is a breakdown of energy generation in the US: https://www.eia.gov/tools/faqs/faq.php?id=427&t=3 https://www.eia.gov/tools/faqs/faq.php?id=427&t=3 63% of power generation comes from "fossil fuels", but half of that comes from natural gas. If we focus purely on carbon emissions and ignore implications of fracking, natural gas can be considered "clean". Also assuming all renewables are zero-emission, this means roughly 30% of our power generation has the potential for carbon emissions. By simply instituting a carbon tax, or even requiring coal plants to sequester emissions would make burning coal expensive enough that other forms of power will become cheaper, and thus the market would align appropriately. These are things being talked about right now, so its not unrealistic. The coal lobby won't like this of course and will continue to push us away from that, but I believe in 50 years when Miami and New Orleans have turned into Venice and the new generation of people won't be working in coal, American conservatives, as well as other nations, will stop complaining about the coal industry so much. All that has to happen is a few percentage points in a certain direction and the machinations will start to work.
