Efficient un-allocation of cloud resources
Cloud services require the outward appearance of unlimited resources with flexible availability for varying demand. However, while on-demand allocation and deallocation of resources may seem efficient, there are significant cases where simply allocating and deallocating resources just in response to demand results in inefficiencies. As discussed herein, cloud services can be made more efficient by deallocating resources based on delays incurred between when resources are requested to be deallocated and reallocated and when they actually are deallocated and allocated, and for how long the resource would be returned to the cloud before needing to be reallocated. Deallocating resources more efficiently not only gives a direct performance improvement, but also indirect, since deallocated resources may not be available again when demand increases. |

Personal power plant system and methods of inverse energy generation
A personal power plant stores energy at the load site from renewable sources and through connection with a utility, enabling the personal power plant to support real time or near real time system load balancing and to eliminate net-metering. The personal power plant determines a charging profile based on predicted energy usage for a next 24-hour period. The personal power plant can provide an indication of the excess amount of electrical energy stored, but not needed for the next 24-hour period. When times of high demand are anticipated, the utility can reallocate energy to other users which it would otherwise provide to participating personal power plants aggregating the excess energy from a plurality of personal power plants. At such times, inverse power generation occurs as the personal power plants do not draw power from the grid which, in aggregation, reduces grid load. |
